Konzept
Im vorigen Artikel habe ich die Steuerelemente für die Verwaltung von Ankerpunkten für grafische Basisobjekte hinzugefügt, um zusammengesetzte grafische Objekte zu handhaben. Meine Idee ist, dass das Verschieben solcher Steuerelemente eine Verlagerung des Ankerpunkts des grafischen Basisobjekts nach sich zieht, wodurch sich seine räumliche Ausrichtung innerhalb eines Charts ändert. Um diese Kontrollpunkte mit der Maus zu verschieben, müssen wir die Ereignisbehandlung der Maus für die Hintergrundobjekt (canvas, grafisches Element und Formularobjekt) erstellen. Wenn der Mauszeiger über dem Formularobjekt schwebt, soll es das wissen und seine Eigenschaften ändern. Zusätzlich sollte berücksichtigt werden, ob der Nutzer die Maustaste gedrückt hält. Wenn wir die Maustaste innerhalb eines Formularobjekts drücken und es zu bewegen beginnen, sollte das Scrollen des Charts mit der Maus deaktiviert werden (zusammen mit dem Fadenkreuz-Werkzeug und dem Kontextmenü des Charts), während das Formular selbst dem Cursor folgen sollte.
Die übrigen Formularobjekte sollten nicht reagieren, wenn die Maus mit gedrückter Taste sie erreicht. Wenn wir die Maustaste außerhalb eines Formulars drücken und den Cursor bewegen, wird das gesamte Chart verschoben (sofern dies in den Einstellungen erlaubt ist), während Formularobjekte nicht reagieren sollten, wenn der Cursor mit gedrückter Taste sie erreicht, um eine Verschiebung von Formularen zu vermeiden.
In den kommenden Artikeln werde ich nach und nach die gleiche Funktionsweise für Formularobjekte schaffen und die Entwicklung von zusammengesetzten grafischen Objekten fortsetzen.
Außerdem werde ich die Symbolobjektklasse verbessern, da die Chart-Symbole jetzt neue Eigenschaften haben, die berücksichtigt und verfolgt werden müssen. Die neuen Eigenschaften sind nicht so zahlreich, aber der Inhalt einiger Eigenschaften ist ziemlich beträchtlich in Bezug auf die Anzahl der Enumerationskonstanten, die diese Eigenschaften beschreiben (ENUM_SYMBOL_SECTOR, ENUM_SYMBOL_INDUSTRY). Daher wird es mehrere neue Nachrichtenindizes für die Nachrichtenklasse der Bibliothek geben, und die Methoden, die die Eigenschaftsbeschreibungen zurückgeben, werden ebenfalls recht umfangreich sein.
Verbesserung der Klassenbibliothek

Jedes Formularobjekt soll nun eine neue Eigenschaft "Interaktion mit der Umgebung" haben. Ist die Eigenschaft gesetzt, bedeutet dies, dass das Objekt auf Mausaktionen entsprechend seinem Status reagieren soll. Die übrigen Formularobjekte sollen das Flag in einer zurückgesetzten Form haben. Dies ermöglicht es uns, das Formular auszuwählen, über dem der Cursor mit der gedrückten Taste schwebte, sowie alle anderen notwendigen Aktionen, die nur mit einem einzigen Formular durchgeführt werden können, damit das Chart nicht auf Mausaktionen reagiert.

Zunächst wird der gültige Präfixwert hier in der Initialisierungsliste gesetzt. Weiterhin wurde im Konstruktorkörper der Wert als leere Zeichenkette gesetzt, was zu Fehlern bei der Identifizierung von grafischen Objekten bei deren Handhabung führte.
Wir löschen die Zeichenkette und entfernen das Setzen des Verschiebungs- und Sichtbarkeitsflags aus der Initialisierungsliste, da sie im Konstruktorkörper gesetzt sind:
//+------------------------------------------------------------------+ //| Constructor | //+------------------------------------------------------------------+ CGBaseObj::CGBaseObj() : m_name_prefix(::MQLInfoString(MQL_PROGRAM_NAME)+"_"),m_belong(GRAPH_OBJ_BELONG_PROGRAM) { this.m_list_events.Clear(); // Clear the event list this.m_list_events.Sort(); // Sorted list flag this.m_type=OBJECT_DE_TYPE_GBASE; // Object type this.m_type_graph_obj=WRONG_VALUE; // Graphical object type this.m_type_element=WRONG_VALUE; // Graphical object type this.m_belong=WRONG_VALUE; // Program/terminal affiliation this.m_group=0; // Graphical object group this.m_name=""; // Object name this.m_chart_id=0; // Object chart ID this.m_object_id=0; // Object ID this.m_zorder=0; // Priority of a graphical object for receiving the mouse click event this.m_subwindow=0; // Subwindow index this.m_shift_y=0; // Subwindow Y coordinate shift this.m_timeframes_visible=OBJ_ALL_PERIODS; // Visibility of an object on timeframes (a set of flags) this.m_visible=true; // Object visibility this.m_back=false; // "Background object" flag this.m_selected=false; // "Object selection" flag this.m_selectable=false; // "Object availability" flag this.m_hidden=true; // "Disable displaying the name of a graphical object in the terminal object list" flag this.m_create_time=0; // Object creation time } //+------------------------------------------------------------------+
Im öffentlichen Abschnitt der Klasse schreiben wir die Methode, die den Präfix des grafischen Objektnamens zurückgibt:

Verbessern wir die grafische Elementobjektklasse auf der Leinwand in \MQL5\Include\DoEasy\Objects\Graph\GCnvElement.mqh.
Zuvor habe ich auch hier einige Fehler gemacht. Wir müssen also die Methoden für die Handhabung der neuen Eigenschaft "Interaktion" hinzufügen.
Verschieben wir die Methoden, die die Cursorposition relativ zum gesamten Element oder seinem aktiven Bereich zurückgeben, aus dem geschützten Bereich in den öffentlichen Bereich:
//+------------------------------------------------------------------+ //| Class of the graphical element object | //+------------------------------------------------------------------+ class CGCnvElement : public CGBaseObj { protected: CCanvas m_canvas; // CCanvas class object CPause m_pause; // Pause class object bool m_shadow; // Shadow presence color m_chart_color_bg; // Chart background color uint m_duplicate_res[]; // Array for storing resource data copy //--- Return the cursor position relative to the (1) entire element and (2) the element's active area bool CursorInsideElement(const int x,const int y); bool CursorInsideActiveArea(const int x,const int y); //--- Create (1) the object structure and (2) the object from the structure virtual bool ObjectToStruct(void); virtual void StructToObject(void); private: //--- (1) Save the graphical resource to the array and (2) restore the resource from the array bool ResourceStamp(const string source); virtual bool Reset(void); //--- Return the cursor position relative to the (1) entire element and (2) the element's active area bool CursorInsideElement(const int x,const int y); bool CursorInsideActiveArea(const int x,const int y); //--- Create the element bool Create(const long chart_id, const int wnd_num, const string name, const int x, const int y, const int w, const int h, const color colour, const uchar opacity, const bool redraw=false); //--- Return the pointer to a canvas object
Wir werden sie brauchen, um ein externes Objekt in der Klasse der grafischen Elementsammlung zu verwalten.
Im privaten Teil der Klasse erhält die Struktur, die die Objekteigenschaften speichert, um das Objekt zu speichern und aus ihm zu lesen die neue Eigenschaft:
//+------------------------------------------------------------------+ //| Class of the graphical element object | //+------------------------------------------------------------------+ class CGCnvElement : public CGBaseObj { protected: CCanvas m_canvas; // CCanvas class object CPause m_pause; // Pause class object bool m_shadow; // Shadow presence color m_chart_color_bg; // Chart background color uint m_duplicate_res[]; // Array for storing resource data copy //--- Create (1) the object structure and (2) the object from the structure virtual bool ObjectToStruct(void); virtual void StructToObject(void); private: struct SData { //--- Object integer properties int id; // Element ID int type; // Graphical element type int number; // Element index in the list long chart_id; // Chart ID int subwindow; // Chart subwindow index int coord_x; // Form's X coordinate on the chart int coord_y; // Form's Y coordinate on the chart int width; // Element width int height; // Element height int edge_right; // Element right border int edge_bottom; // Element bottom border int act_shift_left; // Active area offset from the left edge of the element int act_shift_top; // Active area offset from the top edge of the element int act_shift_right; // Active area offset from the right edge of the element int act_shift_bottom; // Active area offset from the bottom edge of the element uchar opacity; // Element opacity color color_bg; // Element background color bool movable; // Element moveability flag bool active; // Element activity flag bool interaction; // Flag of interaction with the outside environment int coord_act_x; // X coordinate of the element active area int coord_act_y; // Y coordinate of the element active area int coord_act_right; // Right border of the element active area int coord_act_bottom; // Bottom border of the element active area //--- Object real properties //--- Object string properties uchar name_obj[64]; // Graphical element object name uchar name_res[64]; // Graphical resource name }; SData m_struct_obj; // Object structure uchar m_uchar_array[]; // uchar array of the object structure long m_long_prop[ORDER_PROP_INTEGER_TOTAL]; // Integer properties double m_double_prop[ORDER_PROP_DOUBLE_TOTAL]; // Real properties string m_string_prop[ORDER_PROP_STRING_TOTAL]; // String properties
Im öffentlichen Abschnitt der Klasse deklarieren wir die virtuelle Ereignisbehandlung:
protected: //--- Protected constructor CGCnvElement(const ENUM_GRAPH_ELEMENT_TYPE element_type, const long chart_id, const int wnd_num, const string name, const int x, const int y, const int w, const int h); public: //--- Event handler virtual void OnChartEvent(const int id,const long& lparam,const double& dparam,const string& sparam); //--- Parametric constructor CGCnvElement(const ENUM_GRAPH_ELEMENT_TYPE element_type, const int element_id, const int element_num, const long chart_id, const int wnd_num, const string name, const int x, const int y, const int w, const int h, const color colour, const uchar opacity, const bool movable=true, const bool activity=true, const bool redraw=false); //--- Default constructor/Destructor CGCnvElement() : m_shadow(false),m_chart_color_bg((color)::ChartGetInteger(::ChartID(),CHART_COLOR_BACKGROUND)) { this.m_type=OBJECT_DE_TYPE_GELEMENT; } ~CGCnvElement() { this.m_canvas.Destroy(); }
Da andere Objekte, einschließlich des Formularobjekts, von diesem abgeleitet werden sollen, benötigen wir eine virtuelle Ereignisbehandlung. Die Kollektionsliste der grafischen Elemente speichert die Objekte der Klasse CGCnvElement. Aber auch ihre Nachkommen können dort abgelegt werden. Wenn also das Objekt der Klasse CForm aus der Liste geholt wird, wird beim Zugriff auf die Ereignisbehandlung des Objekts die Ereignisbehandlung der Klasse CForm aufgerufen, da er auch die virtuelle Ereignisbehandlung enthält.
Im Methodenblock für einen vereinfachten Zugriff auf die Objekteigenschaften, setzen wir zwei neue Methoden für die Behandlung der Eigenschaft "Interaktion":

Im parametrischen Konstruktor wird das Vorhandensein einer Teilzeichenkette mit dem Programmnamen in der Zeichenkette des in den Konstruktorparametern übergebenen Namens überprüft. Ist keine Teilzeichenkette vorhanden, erhält der an die Methode übergebene Name den Programmnamen als Präfix des Objektnamens. Wenn die Teilzeichenkette vorhanden ist, wird nichts hinzugefügt. Auf diese Weise lässt sich die Verdoppelung des Objektnamens-Präfixes vermeiden, wenn er bereits in den Konstruktorparametern innerhalb des Namens in der Variablen Name übergeben wurde:

Ganz am Ende der Dateiliste implementieren wir die virtuelle Ereignisbehandlung:
//+------------------------------------------------------------------+ //| Event handler | //+------------------------------------------------------------------+ void CGCnvElement::OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam) { //--- In case of a chart change event, recalculate the shift by Y for the subwindow if(id==CHARTEVENT_CHART_CHANGE) { this.m_shift_y=(int)::ChartGetInteger(this.ChartID(),CHART_WINDOW_YDISTANCE,this.WindowNum()); } } //+------------------------------------------------------------------+
Hier ist alles einfach. Wenn das Ereignis einer Änderung des Chartfensters eintrifft, müssen wir den Wert der vertikalen Verschiebung der Teilfensterkoordinate neu berechnen, da sich seine Größe ändern kann. Das bedeutet, dass wir die Anzahl der Pixel für die Anpassung der Y-Koordinate entsprechend ändern sollten.
Formularobjekte. Entwicklung der Funktionsweisen zur Handhabung der Maus
Als eigenständiges Element grafischer Konstruktionen sollte das Formularobjekt Zugriff auf die Parameter des Mauszeigers und einer eigenen Ereignisbehandlung haben, der einige Formulareigenschaften setzt, wenn es auf verschiedene Weise mit der Maus interagiert.
Um dies zu erreichen, enthält die Datei \MQL5\Include\DoEasy\Objects\Graph\Form.mqh des Formularobjekts die Maus-Statusdatei, während im privaten Klassenteil die Variablen deklariert werden, die für die Handhabung des Objekts der Maus-Eigenschaften notwendig sind:

Im öffentlichen Abschnitt der Klasse deklarieren wir die Methoden für die Behandlung des Mausstatusobjekts und den virtuellen Ereignishandler des Formularobjekts:
public: //--- Return the mouse status relative to the form ENUM_MOUSE_FORM_STATE MouseFormState(const int id,const long lparam,const double dparam,const string sparam); //--- Set the flags of mouse scrolling, context menu and the crosshairs tool for the chart void SetChartTools(const bool flag); //--- (1) Set and (2) return the shift of X and Y coordinates relative to the cursor void SetOffsetX(const int value) { this.m_offset_x=value; } void SetOffsetY(const int value) { this.m_offset_y=value; } int OffsetX(void) const { return this.m_offset_x; } int OffsetY(void) const { return this.m_offset_y; } //--- Return the (1) X and (2) Y coordinate of the cursor int MouseCursorX(void) const { return this.m_mouse.CoordX(); } int MouseCursorY(void) const { return this.m_mouse.CoordY(); } //--- Event handler virtual void OnChartEvent(const int id,const long& lparam,const double& dparam,const string& sparam); //--- Constructors CForm(const long chart_id, const int subwindow, const string name, const int x, const int y, const int w, const int h); CForm(const int subwindow, const string name, const int x, const int y, const int w, const int h); CForm(const string name, const int x, const int y, const int w, const int h); CForm() { this.m_type=OBJECT_DE_TYPE_GFORM; this.Initialize(); } //--- Destructor ~CForm();
In der Methode zur Initialisierung der Klassenvariablen setzen wir die Standardvariablen für die Maustasten- und Cursorbewegungsflags und rufen wir die übergeordnete Klassenmethode auf, um das Flag für die Interaktion zwischen dem Formular und der Maus zu setzen:
//+------------------------------------------------------------------+ //| Initialize the variables | //+------------------------------------------------------------------+ void CForm::Initialize(void) { this.m_list_elements.Clear(); this.m_list_elements.Sort(); this.m_shadow_obj=NULL; this.m_shadow=false; this.m_frame_width_right=2; this.m_frame_width_left=2; this.m_frame_width_top=2; this.m_frame_width_bottom=2; this.m_mouse_state_flags=0; this.m_offset_x=0; this.m_offset_y=0; CGCnvElement::SetInteraction(false); this.m_animations=new CAnimations(CGCnvElement::GetObject()); } //+------------------------------------------------------------------+
Schreiben wir noch die Methode, die den Mausstatus relativ zum Formular zurückgibt:
//+------------------------------------------------------------------+ //| Return the mouse status relative to the form | //+------------------------------------------------------------------+ ENUM_MOUSE_FORM_STATE CForm::MouseFormState(const int id,const long lparam,const double dparam,const string sparam) { //--- Get the mouse status relative to the form, as well as the states of mouse buttons and Shift/Ctrl keys ENUM_MOUSE_FORM_STATE form_state=MOUSE_FORM_STATE_OUTSIDE_NOT_PRESSED; ENUM_MOUSE_BUTT_KEY_STATE state=this.m_mouse.ButtonKeyState(id,lparam,dparam,sparam); //--- Get the mouse status flags from the CMouseState class object and save them in the variable this.m_mouse_state_flags=this.m_mouse.GetMouseFlags(); //--- If the cursor is inside the form if(CGCnvElement::CursorInsideElement(m_mouse.CoordX(),m_mouse.CoordY())) { //--- Set bit 8 responsible for the "cursor inside the form" flag this.m_mouse_state_flags |= (0x0001<<8); //--- If the cursor is inside the active area, set bit 9 "cursor inside the active area" if(CGCnvElement::CursorInsideActiveArea(m_mouse.CoordX(),m_mouse.CoordY())) this.m_mouse_state_flags |= (0x0001<<9); //--- otherwise, release the bit "cursor inside the active area" else this.m_mouse_state_flags &=0xFDFF; //--- If one of the mouse buttons is clicked, check the cursor location in the active area and //--- return the appropriate value of the pressed key (in the active area or the form area) if((this.m_mouse_state_flags & 0x0001)!=0 || (this.m_mouse_state_flags & 0x0002)!=0 || (this.m_mouse_state_flags & 0x0010)!=0) form_state=((this.m_mouse_state_flags & 0x0200)!=0 ? MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_PRESSED : MOUSE_FORM_STATE_INSIDE_PRESSED); //--- otherwise, if not a single mouse button is pressed else { //--- if the mouse wheel is scrolled, return the appropriate wheel scrolling value (in the active area or the form area) if((this.m_mouse_state_flags & 0x0080)!=0) form_state=((this.m_mouse_state_flags & 0x0200)!=0 ?

MOUSE_FORM_STATE_OUTSIDE_PRESSED : MOUSE_FORM_STATE_OUTSIDE_NOT_PRESSED); } return form_state; } //+------------------------------------------------------------------+
Wir haben diese Methode ausführlich im Artikel 73 beim Erstellen eines Testformularobjekts betrachtet. Jetzt wurde die Methode leicht erweitert, um den Zustand der Maustasten zu verfolgen, wenn der Cursor außerhalb des Formulars platziert wird. Die Logik der Methode ist im Programm detailliert beschrieben. In jedem Fall können Sie gerne den Abschnitt Kommentare verwenden.
Die Ereignisbehandlung des Formularobjekts:
//+------------------------------------------------------------------+ //| Event handler | //+------------------------------------------------------------------+ void CForm::OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam) { CGCnvElement::OnChartEvent(id,lparam,dparam,sparam); //--- Get the status of mouse buttons, as well as of Shift and Ctrl keys this.m_mouse_form_state=this.MouseFormState(id,lparam,dparam-this.m_shift_y,sparam); //--- Check, at which chart location the mouse button has been (and is still) pressed – outside the form or inside it //--- If the left mouse button is pressed, consider it pressed bool pressed=(this.m_mouse.ButtonKeyState(id,lparam,dparam,sparam)==MOUSE_BUTT_KEY_STATE_LEFT ? true : false); //--- If the left mouse button is pressed outside the form, set its pressed_chart variable to 'true' bool pressed_chart=(this.m_mouse_form_state==MOUSE_FORM_STATE_OUTSIDE_PRESSED && this.m_mouse.ButtonKeyState(id,lparam,dparam,sparam)==MOUSE_BUTT_KEY_STATE_LEFT ? true : false); //--- If the left mouse button is pressed inside the form, set the pressed_form variable to 'true' bool pressed_form=(pressed_chart ? false : this.m_mouse_form_state==MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_PRESSED && this.m_mouse.ButtonKeyState(id,lparam,dparam,sparam)==MOUSE_BUTT_KEY_STATE_LEFT ? true : false); //--- If the button was pressed on the chart for its relocation, if(pressed_chart) { //--- reset the interaction flag and allow scrolling the chart using the mouse wheel, the context menu and the Crosshairs tool this.SetInteraction(false); this.SetChartTools(true); } //--- Otherwise, if the button inside the form is pressed and the interaction flag is not set yet, else if(pressed_form && !this.Interaction()) { //--- move the form above all the rest, set the interaction flag, //--- disable scrolling the chart with the mouse wheel, the chart context menu and the Crosshairs tool, //--- and set the mouse cursor shift values inside the form relative to its coordinate origin in the upper left corner this.BringToTop(); this.SetInteraction(CGCnvElement::Active() ? true : false); this.SetChartTools(CGCnvElement::Active() ? false : true); this.m_offset_x=this.m_mouse.CoordX()-this.CoordX(); this.m_offset_y=this.m_mouse.CoordY()-this.CoordY(); } //--- In case of the cursor movement event if(id==CHARTEVENT_MOUSE_MOVE) { //--- If the interaction flag is set for the form if(this.Interaction()) { //--- If the left mouse button is pressed inside the form active area if(this.MouseFormState(id,lparam,dparam,sparam)==MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_PRESSED) { //--- If the form follows the cursor if(this.Move(this.m_mouse.CoordX()-this.m_offset_x,this.m_mouse.CoordY()-this.m_offset_y,true)) { //--- Set the new cursor movement values relative to the form coordinate origin this.m_offset_x=this.m_mouse.CoordX()-this.CoordX(); this.m_offset_y=this.m_mouse.CoordY()-this.CoordY(); } } } //--- Display the comment with the control variable values on the chart Comment ( this.Name(),":\n", EnumToString((ENUM_CHART_EVENT)id),"\n", EnumToString(this.m_mouse.ButtonKeyState(id,lparam,dparam,sparam)), "\n",EnumToString(this.m_mouse_form_state), "\npressed=",pressed,", pressed_chart=",pressed_chart,", pressed_form=",pressed_form,", Interaction=",Interaction() ); } } //+------------------------------------------------------------------+
Die Methode ist ebenfalls ausführlich kommentiert. Bei einem Chart-Ereignis prüft die Ereignisbehandlung zunächst den Maustastenstatus und die Cursorposition. Danach werden die Flags des allgemeinen Mausstatus gesetzt (linke Maustaste auf dem Chart oder innerhalb des aktiven Formularbereichs gedrückt). Dann werden die Flags für die Verzweigung der Logik der Ereignisbehandlung verwendet. Die Idee ist, dass, wenn die Maustaste außerhalb des Formulars gedrückt wird, zusätzliche Werkzeuge für das Chart zugelassen werden (Maus-Scrolling, Kontextmenü und Fadenkreuz), während das Flag für die Interaktion des Formulars mit der Maus zurückgesetzt wird.
Wenn die linke Maustaste innerhalb des aktiven Formularbereichs gedrückt wird, werden zusätzliche Werkzeuge für das Chart deaktiviert, während das Flag der Interaktion mit der Maus für das Formular gesetzt wird.
Dies sollte letztendlich zu folgendem Verhalten führen: wenn wir das Formular mit der Maustaste halten, können wir es verschieben, ohne den gesamten Chart zu bewegen. Wenn wir mit dem Mausrad innerhalb des Formulars scrollen, sollte das Diagramm fixiert bleiben (da das Formular andere Elemente enthalten soll, die das Scrollen mit dem Mausrad unterstützen, während das Diagramm nicht darauf reagieren soll).
Gleichzeitig sollte nur ein Formular für die Interaktion mit der Maus aktiv bleiben (das Formular im Vordergrund, das von der Schaltfläche gehalten wird oder über dem der Mauszeiger schwebt). All dies werde ich später schrittweise implementieren.
Die Methode zum Setzen der Flags für das Scrollen des Charts mit der Maus, das Kontextmenü und das Fadenkreuz-Werkzeug für den Chart:
//+------------------------------------------------------------------+ //| Set the flags of mouse scrolling, | //| context menu and crosshairs for the chart | //+------------------------------------------------------------------+ void CForm::SetChartTools(const bool flag) { ::ChartSetInteger(this.ChartID(),CHART_MOUSE_SCROLL,flag); ::ChartSetInteger(this.ChartID(),CHART_CONTEXT_MENU,flag); ::ChartSetInteger(this.ChartID(),CHART_CROSSHAIR_TOOL,flag); } //+------------------------------------------------------------------+
Die Methode erhält das Flag. Der Flag-Wert wird für jede Chart-Eigenschaft gesetzt.
Da die zusammengesetzten grafischen Objekte auch Formularobjekte als Steuerobjekte für die Ankerpunkte des grafischen Basisobjekts enthalten, wollen wir die erweiterte Standard-Grafikobjekt-Toolkit-Klasse in \MQL5\Include\DoEasy\Objects\Graph\Extend\CGStdGraphObjExtToolkit.mqh leicht verbessern.
In der Ereignisbehandlung wird die Behandlung der Mausbewegungen hinzugefügt:
//+------------------------------------------------------------------+ //| Event handler | //+------------------------------------------------------------------+ void CGStdGraphObjExtToolkit::OnChartEvent(const int id,const long& lparam,const double& dparam,const string& sparam) { if(id==CHARTEVENT_CHART_CHANGE) { for(int i=0;i<this.m_list_forms.Total();i++) { CForm *form=this.m_list_forms.At(i); if(form==NULL) continue; int x=0, y=0; if(!this.GetControlPointCoordXY(i,x,y)) continue; form.SetCoordX(x-this.m_shift); form.SetCoordY(y-this.m_shift); form.Update(); } ::ChartRedraw(this.m_base_chart_id); } if(id==CHARTEVENT_MOUSE_MOVE) { for(int i=0;i<this.m_list_forms.Total();i++) { CForm *form=this.m_list_forms.At(i); if(form==NULL) continue; form.OnChartEvent(id,lparam,dparam,sparam); } ::ChartRedraw(this.m_base_chart_id); } } //+------------------------------------------------------------------+
Hier rufen wir die Ereignisbehandlung jedes nachfolgenden Formularobjekts in einer Schleife durch die Liste der Formularobjekte eines zusammengesetzten grafischen Objekts auf. Die Methode wird verbessert werden, wenn ich meine Arbeit an den zusammengesetzten grafischen Objekten fortsetze.
Das Objekt der Klasse wird in das erweiterte Standard-Grafikobjekt eingebunden. Um auf die oben erwähnte Ereignisbehandlung zugreifen zu können, werde ich die entsprechende Ereignisbehandlung in der Klasse des Standard-Grafikobjekts verbessern.
Wir öffnen die Datei der Standard-Grafikobjekt-Klasse \MQL5\Include\DoEasy\Objects\Graph\Standard\GStdGraphObj.mqh und fügen einige Verbesserungen hinzu.
Im geschützten parametrischen Konstruktor wird überprüft, ob das Objekt erweitert ist. Wenn ja, setze die Auswahl- und Verfügbarkeitsflags dafür auf false. Im Falle eines gewöhnlichen Standard-Grafikobjekts werden die Flags dieser Eigenschaften direkt aus dem Grafischen Objekt übernommen:

In der Ereignisbehandlung des Standard-Grafikobjekts senden wir den Namen des aktuellen Grafikobjekts im Parameter sparam an die Ereignisbehandlung des Hilfsobjekts für das erweiterte Grafikobjekt. Außerdem fügen wir die Behandlung von Mausbewegungsereignissen hinzu:
//+------------------------------------------------------------------+ //| Event handler | //+------------------------------------------------------------------+ void CGStdGraphObj::OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam) { if(GraphElementType()!=GRAPH_ELEMENT_TYPE_STANDARD_EXTENDED) return; string name=this.Name(); if(id==CHARTEVENT_CHART_CHANGE) { if(ExtToolkit==NULL) return; for(int i=0;i<this.Pivots();i++) { ExtToolkit.SetBaseObjTimePrice(this.Time(i),this.Price(i),i); } ExtToolkit.SetBaseObjCoordXY(this.XDistance(),this.YDistance()); ExtToolkit.OnChartEvent(id,lparam,dparam,name); } if(id==CHARTEVENT_MOUSE_MOVE) { if(ExtToolkit!=NULL) ExtToolkit.OnChartEvent(id,lparam,dparam,name); } } //+------------------------------------------------------------------+
Dies sind alles Änderungsentwürfe, auf die ich jetzt nicht näher eingehen werde. Ich werde mich mit ihnen befassen, wenn ich an zusammengesetzten grafischen Objekten arbeite.
Die Formularobjekte werden von der Klasse für die Kollektion grafischer Elemente verwaltet. Dieselbe Klasse enthält die Liste zum Speichern der Zeiger auf grafische Elemente. Die Liste soll alle erstellten Formulare aufnehmen. Im Moment werden wir dies manuell tun. Später werde ich die Funktionsweise implementieren, durch die die Objekte sofort nach ihrer Erstellung in die Liste aufgenommen werden.
Die Klassendatei \MQL5\Include\DoEasy\Collections\GraphElementsCollection.mqh enthält eine weitere Klasse zur Verwaltung von Chart-Objekten. Fügen wir noch die überladenen Methoden zum Setzen der Flags hinzufügen, die das Chart-Toolkit erlauben — drehen des Rads, Mausbewegung, Kontextmenü und das Fadenkreuz:
//+------------------------------------------------------------------+ //| Chart object management class | //+------------------------------------------------------------------+ class CChartObjectsControl : public CObject { private: CArrayObj m_list_new_graph_obj; // List of added graphical objects ENUM_TIMEFRAMES m_chart_timeframe; // Chart timeframe long m_chart_id; // Chart ID long m_chart_id_main; // Control program chart ID string m_chart_symbol; // Chart symbol bool m_is_graph_obj_event; // Event flag in the list of graphical objects int m_total_objects; // Number of graphical objects int m_last_objects; // Number of graphical objects during the previous check int m_delta_graph_obj; // Difference in the number of graphical objects compared to the previous check int m_handle_ind; // Event controller indicator handle string m_name_ind; // Short name of the event controller indicator string m_name_program; // Program name //--- Return the name of the last graphical object added to the chart string LastAddedGraphObjName(void); //--- Set the permission to track mouse events and graphical objects void SetMouseEvent(void); public: //--- Return the variable values ENUM_TIMEFRAMES Timeframe(void) const { return this.m_chart_timeframe; } long ChartID(void) const { return this.m_chart_id; } string Symbol(void) const { return this.m_chart_symbol; } bool IsEvent(void) const { return this.m_is_graph_obj_event; } int TotalObjects(void) const { return this.m_total_objects; } int Delta(void) const { return this.m_delta_graph_obj; } //--- Set the flags of scrolling the chart with the mouse, context menu and crosshairs tool for the chart void SetChartTools(const bool flag); void SetChartTools(const bool mouse_scroll,const bool context_menu,const bool crosshair_tool); //--- Create a new standard (or extended) graphical object CGStdGraphObj *CreateNewGraphObj(const ENUM_OBJECT obj_type,const string name,const bool extended); //--- Return the list of newly added objects CArrayObj *GetListNewAddedObj(void) { return &this.m_list_new_graph_obj;} //--- Create the event control indicator bool CreateEventControlInd(const long chart_id_main); //--- Add the event control indicator to the chart bool AddEventControlInd(void); //--- Check the chart objects void Refresh(void); //--- Constructors CChartObjectsControl(void) { this.m_name_program=::MQLInfoString(MQL_PROGRAM_NAME); this.m_chart_id=::ChartID(); this.m_chart_timeframe=(ENUM_TIMEFRAMES)::ChartPeriod(this.m_chart_id); this.m_chart_symbol=::ChartSymbol(this.m_chart_id); this.m_chart_id_main=::ChartID(); this.m_list_new_graph_obj.Clear(); this.m_list_new_graph_obj.Sort(); this.m_is_graph_obj_event=false; this.m_total_objects=0; this.m_last_objects=0; this.m_delta_graph_obj=0; this.m_name_ind=""; this.m_handle_ind=INVALID_HANDLE; this.SetMouseEvent(); } CChartObjectsControl(const long chart_id) { this.m_name_program=::MQLInfoString(MQL_PROGRAM_NAME); this.m_chart_timeframe=(ENUM_TIMEFRAMES)::ChartPeriod(chart_id); this.m_chart_symbol=::ChartSymbol(chart_id); this.m_chart_id_main=::ChartID(); this.m_list_new_graph_obj.Clear(); this.m_list_new_graph_obj.Sort(); this.m_chart_id=chart_id; this.m_is_graph_obj_event=false; this.m_total_objects=0; this.m_last_objects=0; this.m_delta_graph_obj=0; this.m_name_ind=""; this.m_handle_ind=INVALID_HANDLE; this.SetMouseEvent(); } //--- Destructor ~CChartObjectsControl() { ::ChartIndicatorDelete(this.ChartID(),0,this.m_name_ind); ::IndicatorRelease(this.m_handle_ind); } //--- Compare CChartObjectsControl objects by a chart ID (for sorting the list by an object property) virtual int Compare(const CObject *node,const int mode=0) const { const CChartObjectsControl *obj_compared=node; return(this.ChartID()>obj_compared.ChartID() ? 1 : this.ChartID()<obj_compared.ChartID() ? -1 : 0); } //--- Event handler void OnChartEvent(const int id, const long &lparam, const double &dparam, const string &sparam); }; //+------------------------------------------------------------------+
Schreiben wir ihre Implementierung außerhalb des Klassenkörpers:
//+------------------------------------------------------------------+ //| Set the flags of mouse scrolling, | //| context menu and crosshairs for the chart | //+------------------------------------------------------------------+ void CChartObjectsControl::SetChartTools(const bool flag) { ::ChartSetInteger(this.ChartID(),CHART_MOUSE_SCROLL,flag); ::ChartSetInteger(this.ChartID(),CHART_CONTEXT_MENU,flag); ::ChartSetInteger(this.ChartID(),CHART_CROSSHAIR_TOOL,flag); } //+------------------------------------------------------------------+ //| Set the flags of mouse scrolling, | //| context menu and crosshairs for the chart | //+------------------------------------------------------------------+ void CChartObjectsControl::SetChartTools(const bool mouse_scroll,const bool context_menu,const bool crosshair_tool) { ::ChartSetInteger(this.ChartID(),CHART_MOUSE_SCROLL,mouse_scroll); ::ChartSetInteger(this.ChartID(),CHART_CONTEXT_MENU,context_menu); ::ChartSetInteger(this.ChartID(),CHART_CROSSHAIR_TOOL,crosshair_tool); } //+------------------------------------------------------------------+
Ähnliche Methoden wurden bereits oben betrachtet. Hier besteht der Unterschied darin, dass eine von ihnen die Flaggen für jedes Instrument separat erhält. Diese Methoden können später für die Verwaltung von Charts aus der Klasse der Kollektion der Grafikelemente von Nutzen sein, in der die Methode
bool IsPresentGraphElmInList(const int id,const ENUM_GRAPH_ELEMENT_TYPE type_obj); umbenannt wird in etwas, das vom Grundgedanken her besser geeignet ist und andere Parameter hat.
Außerdem fügen wir die (vorübergehend) öffentliche Methode zum Hinzufügen grafischer Elemente zur Kollektionsliste hinzu:
//+------------------------------------------------------------------+ //| Collection of graphical objects | //+------------------------------------------------------------------+ #resource "\\"+PATH_TO_EVENT_CTRL_IND; // Indicator for controlling graphical object events packed into the program resources class CGraphElementsCollection : public CBaseObj { private: CArrayObj m_list_charts_control; // List of chart management objects CListObj m_list_all_canv_elm_obj; // List of all graphical elements on canvas CListObj m_list_all_graph_obj; // List of all graphical objects CArrayObj m_list_deleted_obj; // List of removed graphical objects bool m_is_graph_obj_event; // Event flag in the list of graphical objects int m_total_objects; // Number of graphical objects int m_delta_graph_obj; // Difference in the number of graphical objects compared to the previous check //--- Return the flag indicating the graphical element class object presence in the collection list of graphical elements bool IsPresentCanvElmInList(const long chart_id,const string name); //--- Return the flag indicating the presence of the graphical object class in the graphical object collection list bool IsPresentGraphObjInList(const long chart_id,const string name); //--- Return the flag indicating the presence of a graphical object on a chart by name bool IsPresentGraphObjOnChart(const long chart_id,const string name); //--- Return the pointer to the object of managing objects of the specified chart CChartObjectsControl *GetChartObjectCtrlObj(const long chart_id); //--- Create a new object of managing graphical objects of a specified chart and add it to the list CChartObjectsControl *CreateChartObjectCtrlObj(const long chart_id); //--- Update the list of graphical objects by chart ID CChartObjectsControl *RefreshByChartID(const long chart_id); //--- Check if the chart window is present bool IsPresentChartWindow(const long chart_id); //--- Handle removing the chart window void RefreshForExtraObjects(void); //--- Return the first free ID of the graphical (1) object and (2) element on canvas long GetFreeGraphObjID(bool program_object); long GetFreeCanvElmID(void); //--- Add (1) the standard graphical object and (2) the graphical element on canvas to the collection bool AddGraphObjToCollection(const string source,CChartObjectsControl *obj_control); public: bool AddCanvElmToCollection(CGCnvElement *element); private:
Im Moment bleibt die Methode öffentlich. Später, wenn implementiert wird, dass neu erstellte grafische Elemente auf der Leinwand sofort nach ihrer Erstellung zur Liste hinzugefügt werden, wird die Methode privat gemacht.
Im privaten Abschnitt der Klasse deklarieren wir die Methode, die die bereits bekannten Chart-Flags setzt:
public: bool AddCanvElmToCollection(CGCnvElement *element); private: //--- Find an object present in the collection but not on a chart CGStdGraphObj *FindMissingObj(const long chart_id); CGStdGraphObj *FindMissingObj(const long chart_id,int &index); //--- Find the graphical object present on a chart but not in the collection string FindExtraObj(const long chart_id); //--- Remove the graphical object class object from the graphical object collection list: (1) specified object, (2) by chart ID bool DeleteGraphObjFromList(CGStdGraphObj *obj); void DeleteGraphObjectsFromList(const long chart_id); //--- Move the graphical object class object to the list of removed graphical objects: (1) specified object, (2) by index bool MoveGraphObjToDeletedObjList(CGStdGraphObj *obj); bool MoveGraphObjToDeletedObjList(const int index); //--- Move all objects by chart ID to the list of removed graphical objects void MoveGraphObjectsToDeletedObjList(const long chart_id); //--- Remove the object of managing charts from the list bool DeleteGraphObjCtrlObjFromList(CChartObjectsControl *obj); //--- Set the flags of scrolling the chart with the mouse, context menu and crosshairs tool for the specified chart void SetChartTools(const long chart_id,const bool flag); public:
In jeder der öffentlichen Methoden zur Erstellung des grafischen Objekts, setzen wir die Auswahl- und Verfügbarkeitsflags auf die gleiche Weise wie oben beschrieben. Nehmen wir die Methode zur Erstellung einer vertikalen Linie als Beispiel:
public: //--- Create the "Vertical line" graphical object bool CreateLineVertical(const long chart_id,const string name,const int subwindow,const bool extended,const datetime time) { //--- Set the name and type of a created object string nm=this.m_name_program+"_"+name; ENUM_OBJECT type_object=OBJ_VLINE; //--- Create a new graphical object and get the pointer to the chart management object CChartObjectsControl *ctrl=this.CreateNewStdGraphObjectAndGetCtrlObj(chart_id,nm,subwindow,type_object,time,0); if(ctrl==NULL) return false; //--- Create a new class object corresponding to the newly created graphical object CGStdVLineObj *obj=ctrl.CreateNewGraphObj(type_object,nm,extended); if(obj==NULL) { ::Print(DFUN,CMessage::Text(MSG_GRAPH_STD_OBJ_ERR_FAILED_CREATE_CLASS_OBJ),StdGraphObjectTypeDescription(type_object)); return false; } //--- Set the necessary minimal parameters for an object obj.SetBelong(GRAPH_OBJ_BELONG_PROGRAM); obj.SetFlagSelected(obj.GraphElementType()==GRAPH_ELEMENT_TYPE_STANDARD_EXTENDED ? false : obj.Selected(),false); obj.SetFlagSelectable(obj.GraphElementType()==GRAPH_ELEMENT_TYPE_STANDARD_EXTENDED ? false : true,false); obj.SetObjectID(this.GetFreeGraphObjID(true)); obj.PropertiesCopyToPrevData(); //--- Return the result of adding the object to the list return this.AddCreatedObjToList(DFUN,chart_id,nm,obj); }
Alle anderen ähnlichen Methoden zur Erstellung von grafischen Objekten wurden bereits in ähnlicher Weise verbessert. Es macht keinen Sinn, sie hier zu besprechen.
Die Methode, die das grafische Element auf der Leinwand zur Kollektion hinzufügt:
//+------------------------------------------------------------------+ //| Add the graphical element on canvas to the collection | //+------------------------------------------------------------------+ bool CGraphElementsCollection::AddCanvElmToCollection(CGCnvElement *element) { if(element==NULL) return false; if(this.IsPresentCanvElmInList(element.ChartID(),element.Name())) { CMessage::ToLog(DFUN+element.Name()+": ",MSG_LIB_SYS_OBJ_ALREADY_IN_LIST); return false; } if(!this.m_list_all_canv_elm_obj.Add(element)) { CMessage::ToLog(DFUN+element.Name()+": ",MSG_LIB_SYS_FAILED_OBJ_ADD_TO_LIST); return false; } return true; } //+------------------------------------------------------------------+
Die Methode erhält den Zeiger auf das grafische Element, das in die Liste eingefügt werden soll.
Wenn das gleiche Objekt bereits in der Liste vorhanden ist, — informiere darüber und gib false zurück.
Wenn der Zeiger nicht in die Liste eingefügt werden konnte, wird dies gemeldet und false zurückgegeben.
Bei Erfolg wird true zurückgegeben.
Die Methode gibt das Flag zurück, das das Vorhandensein des Objekts der grafischen Elementklasse in der Kollektionsliste der grafischen Elemente anzeigt:
//+-------------------------------------------------------------------------------+ //| Return the flag indicating the presence of the graphical element class object | //| in the graphical element collection list | //+-------------------------------------------------------------------------------+ bool CGraphElementsCollection::IsPresentCanvElmInList(const long chart_id,const string name) { CArrayObj *list=CSelect::ByGraphCanvElementProperty(this.GetListCanvElm(),CANV_ELEMENT_PROP_CHART_ID,chart_id,EQUAL); list=CSelect::ByGraphCanvElementProperty(list,CANV_ELEMENT_PROP_NAME_OBJ,name,EQUAL); return(list==NULL || list.Total()==0 ? false : true); } //+------------------------------------------------------------------+
Der Methode werden eine Chart-ID und der Name des Objekts übergeben, dessen Vorhandensein in der Liste geprüft werden soll.
Als Nächstes wird die Liste der Objekte mit der angegebenen Chart ID ermittelt und die erhaltene Liste nach dem erforderlichen Namen sortiert.
Wenn die Liste nicht erhalten werden konnte oder die Liste leer ist, wird false zurückgegeben — das Objekt ist nicht in der Liste, andernfalls wird true zurückgegeben — das Objekt wurde gefunden.
Ereignisbehandlung. Hier fügen wir den Aufruf der Ereignisbehandlung aus der Liste der Standard-Grafikobjekte und Behandlung von Mausereignissen im Zusammenhang mit grafischen Elementen auf der Leinwand:
//+------------------------------------------------------------------+ //| Event handler | //+------------------------------------------------------------------+ void CGraphElementsCollection::OnChartEvent(const int id, const long &lparam, const double &dparam, const string &sparam) { CGStdGraphObj *obj_std=NULL; // Pointer to the standard graphical object CGCnvElement *obj_cnv=NULL; // Pointer to the graphical element object on canvas ushort idx=ushort(id-CHARTEVENT_CUSTOM); if(id==CHARTEVENT_OBJECT_CHANGE || id==CHARTEVENT_OBJECT_DRAG || id==CHARTEVENT_OBJECT_CLICK || idx==CHARTEVENT_OBJECT_CHANGE || idx==CHARTEVENT_OBJECT_DRAG || idx==CHARTEVENT_OBJECT_CLICK) { //--- Calculate the chart ID //--- If the event ID corresponds to an event from the current chart, the chart ID is received from ChartID //--- If the event ID corresponds to a user event, the chart ID is received from lparam //--- Otherwise, the chart ID is assigned to -1 long param=(id==CHARTEVENT_OBJECT_CLICK ? ::ChartID() : idx==CHARTEVENT_OBJECT_CLICK ? lparam : WRONG_VALUE); long chart_id=(param==WRONG_VALUE ? (lparam==0 ? ::ChartID() : lparam) : param); //--- Get the object, whose properties were changed or which was relocated, //--- from the collection list by its name set in sparam obj_std=this.GetStdGraphObject(sparam,chart_id); //--- If failed to get the object by its name, it is not on the list, //--- which means its name has been changed if(obj_std==NULL) { //--- Let's search the list for the object that is not on the chart obj_std=this.FindMissingObj(chart_id); //--- If failed to find the object here as well, exit if(obj_std==NULL) return; //--- Get the name of the renamed graphical object on the chart, which is not in the collection list string name_new=this.FindExtraObj(chart_id); //--- set a new name for the collection list object, which does not correspond to any graphical object on the chart, //--- and send an event with the new name of the object to the control program chart if(obj_std.SetNamePrev(obj_std.Name()) && obj_std.SetName(name_new)) ::EventChartCustom(this.m_chart_id_main,GRAPH_OBJ_EVENT_RENAME,obj_std.ChartID(),obj_std.TimeCreate(),obj_std.Name()); } //--- Update the properties of the obtained object //--- and check their change obj_std.PropertiesRefresh(); obj_std.PropertiesCheckChanged(); } //--- Handle standard graphical object events in the collection list for(int i=0;i<this.m_list_all_graph_obj.Total();i++) { //--- Get the next graphical object and obj_std=this.m_list_all_graph_obj.At(i); if(obj_std==NULL) continue; //--- call its event handler obj_std.OnChartEvent((id<CHARTEVENT_CUSTOM ? id : idx),lparam,dparam,sparam); } //--- Handling mouse events of graphical objects on canvas if(id==CHARTEVENT_MOUSE_MOVE || idx==CHARTEVENT_MOUSE_MOVE) { //--- Get the list of graphical elements with a specified interaction flag (there should be only one object) CArrayObj *list=CSelect::ByGraphCanvElementProperty(GetListCanvElm(),CANV_ELEMENT_PROP_INTERACTION,true,EQUAL); //--- If failed to obtain the list or it is empty if(list==NULL || list.Total()==0) { //--- In the loop by the list of graphical elements for(int i=0;i<this.m_list_all_canv_elm_obj.Total();i++) { //--- Get the next element and call its event handler obj_cnv=this.m_list_all_canv_elm_obj.At(i); if(obj_cnv==NULL) continue; //--- In the event handler, set the interaction flag if the cursor hovers over the form with the pressed mouse button obj_cnv.OnChartEvent(CHARTEVENT_MOUSE_MOVE,lparam,dparam,sparam); } } //--- If the list is received if(list!=NULL) { //--- Get the only object from it obj_cnv=list.At(0); //--- If the object has been received and it is a form object if(obj_cnv!=NULL && obj_cnv.TypeGraphElement()==GRAPH_ELEMENT_TYPE_FORM) { //--- Create the pointer to the obtained form object. If the pointer is received, CForm *form=obj_cnv; if(form!=NULL) { //--- disable moving the chart with a mouse, the chart context menu and the crosshairs tool form.SetChartTools(false); form.OnChartEvent(CHARTEVENT_MOUSE_MOVE,lparam,dparam,sparam); } } } } //--- Handle chart changes for extended standard objects if(id==CHARTEVENT_CHART_CHANGE || idx==CHARTEVENT_CHART_CHANGE) { CArrayObj *list=this.GetListStdGraphObjectExt(); if(list!=NULL) { for(int i=0;i<list.Total();i++) { obj_std=list.At(i); if(obj_std==NULL) continue; obj_std.OnChartEvent(CHARTEVENT_CHART_CHANGE,lparam,dparam,sparam); } } } } //+------------------------------------------------------------------+
Der Codeblock wurde im Programmcode ausführlich kommentiert. Die Idee dahinter ist, dass wir nur ein Formularobjekt haben sollten, mit dem die Maus interagieren kann. Daher prüfen wir zunächst, ob das Objekt vorhanden ist. Ist dies der Fall, arbeiten wir strikt in seiner Ereignisbehandlung.
Die Methode setzt die Flags für das Scrollen des Charts mit der Maus, das Kontextmenü und das Fadenkreuz-Werkzeug für das angegebene Chart:
//+------------------------------------------------------------------+ //| Set the flags of scrolling a chart | //| context menu and crosshairs for the chart | //+------------------------------------------------------------------+ void CGraphElementsCollection::SetChartTools(const long chart_id,const bool flag) { ::ChartSetInteger(chart_id,CHART_MOUSE_SCROLL,flag); ::ChartSetInteger(chart_id,CHART_CONTEXT_MENU,flag); ::ChartSetInteger(chart_id,CHART_CROSSHAIR_TOOL,flag); } //+------------------------------------------------------------------+
Wir kennen diese Methode bereits von den ähnlichen Methoden, die wir zuvor betrachtet haben. Neben dem Flag erhält sie auch die ID des gewünschten Charts.
Um die Kollektionsliste der grafischen Elemente zu handhaben, müssen wir auch den Zugriff auf sie vom Programm aus ermöglichen. Dies geschieht immer in der Hauptklasse der CEngine-Bibliothek in \MQL5\Include\DoEasy\Engine.mqh.
Derzeit reichen zwei öffentliche Methoden zum Testen aus:
//--- Return the class of the object of the extended standard graphical object by chart name and ID CGStdGraphObj *GraphGetStdGraphObjectExt(const string name,const long chart_id) { CArrayObj *list=this.m_graph_objects.GetListStdGraphObjectExt(); string nm=(::StringFind(name,this.ProgramName()+"_")==WRONG_VALUE ? this.ProgramName()+"_"+name : name); list=CSelect::ByGraphicStdObjectProperty(list,GRAPH_OBJ_PROP_NAME,0,nm,EQUAL); return(list!=NULL ? list.At(0) : NULL); } //--- Return the list of graphical elements on canvas CArrayObj *GetListCanvElement(void) { return this.m_graph_objects.GetListCanvElm(); } //--- Add the graphical element on canvas to the collection bool GraphAddCanvElmToCollection(CGCnvElement *element) { return this.m_graph_objects.AddCanvElmToCollection(element); } //--- Fill in the array with IDs of the charts opened in the terminal void GraphGetArrayChartsID(long &array_charts_id[]) { CArrayObj *list=this.m_graph_objects.GetListChartsControl(); if(list==NULL) return; ::ArrayResize(array_charts_id,list.Total()); ::ArrayInitialize(array_charts_id,WRONG_VALUE); for(int i=0;i<list.Total();i++) { CChartObjectsControl *obj=list.At(i); if(obj==NULL) continue; array_charts_id[i]=obj.ChartID(); } }
Eine der Methoden gibt die Liste der grafischen Elemente an die Kollektion zurück, während die zweite Methode ein neu erstelltes grafisches Element zur Kollektion hinzufügt.
Das ist alles, was wir derzeit brauchen, um die neue Funktionsweise zu überprüfen.
Test
Um den Test durchzuführen, verwenden wir den EA aus dem vorherigen Artikel und speichern ihn unter \MQL5\Experts\TestDoEasy\Part96\ als TestDoEasyPart96.mq5.
Entfernen wir noch die Formularobjektliste aus der Liste der globalen EA-Variablen:
//--- global variables CEngine engine; CArrayObj list_forms; color array_clr[];
Wir brauchen die Liste nicht, da die neu erstellten Formulare nun in der Liste der Bibliothekssammlung zu finden sind.
In OnInit() fügen wir den Codeblock mit der Schleife zum Erstellen von zwei Formularobjekten ein:

Hier ist alles ausführlich kommentiert. Außerdem habe ich eine ähnliche Erstellung von Formularobjekten bereits in einigen früheren Artikeln betrachtet.
In der Schleife werden zwei Formulare erstellt. Für sie werden Anzeigeparameter gesetzt, während die Zeiger auf die Formulare in die Sammelliste der Bibliothek gestellt werden.
Kompilieren Sie den EA und starten Sie ihn auf dem Chart. Es werden zwei Formulare erstellt, die unabhängig voneinander mit der Maus gezogen werden können. Das jeweils aktuelle Formular befindet sich immer über anderen Objekten — im Vordergrund, während die Daten eines ausgewählten Formulars in den Kommentaren des Charts angezeigt werden:
Man sieht, dass die Formulare unabhängig voneinander verschoben werden können, während das Chart fixiert bleibt. Jedes aktive Formular befindet sich immer im Vordergrund. Allerdings gibt es auch erhebliche Nachteile: Wenn wir den Chart mit der Maus verschieben und der Cursor den Formularbereich berührt, wird dieser aktiv und kann verwaltet werden. Änderungen der Cursor-Koordinaten in Bezug auf den Formularbezugspunkt können gelegentlich falsch berechnet werden, nachdem das Chart mit der Maus gezogen wurde.
Ich werde alle diese Nachteile bei der weiteren Entwicklung aufspüren und beheben.
Was kommt als Nächstes?
Im nächsten Artikel werde ich meine Arbeit an Ereignissen und Interaktionen zwischen Formularen und Maus fortsetzen.
Alle Dateien der aktuellen Bibliotheksversion, des Test-EA und des Chart-Event-Control-Indikators für MQL5 sind unten zum Testen und Herunterladen angehängt. Stellen Sie Ihre Fragen, Kommentare und Vorschläge bitte im Kommentarteil.

Mathematik im Handel: Sharpe- und Sortino-Ratio
Die Kapitalrendite ist der offensichtlichste Indikator, den Anleger und unerfahrene Händler für die Analyse der Handelseffizienz verwenden. Professionelle Händler verwenden zuverlässigere Instrumente zur Analyse von Strategien, wie z.B. die Sharpe- oder die Sortino-Ratio.
Lernen Sie, wie man ein Handelssystem mit Momentum-Indikator entwickelt
In diesem Artikel werde ich versuchen, eines der wichtigsten Konzepte und Indikatoren zu erläutern, nämlich den Momentum-Indikator, und ich werde erklären, wie man ein Handelssystem mit diesem Momentum-Indikator entwickelt.
MVC-Entwurfsmuster und seine Anwendung (Teil 2): Diagramm der Interaktion zwischen den drei Komponenten
Dieser Artikel ist eine Fortsetzung und Vervollständigung des im vorherigen Artikel behandelten Themas: das MVC-Muster in MQL-Programmen. In diesem Artikel werden wir ein Diagramm der möglichen Interaktion zwischen den drei Komponenten des Musters betrachten.
Grafiken in der DoEasy-Bibliothek (Teil 95): Steuerelemente für zusammengesetzte grafische Objekte
In diesem Artikel befasse ich mich mit den Hilfsmitteln zur Verwaltung zusammengesetzter grafischer Objekte - Steuerelemente zur Verwaltung eines erweiterten grafischen Standardobjekts. Heute werde ich ein wenig vom Verschieben eines zusammengesetzten grafischen Objekts abweichen und den Handler für Änderungsereignisse in einem Chart mit einem zusammengesetzten grafischen Objekt implementieren. Außerdem werde ich mich auf die Steuerelemente für die Verwaltung eines zusammengesetzten grafischen Objekts konzentrieren.
