Inhalt


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

In \MQL5\Include\DoEasy\Data.mqh, fügen wir die neue Nachrichtenindizes hinzu:

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.

Im Artikel 73 habe ich die Statusklasse der Maus implementiert. Ändern wir den Methodennamen in \MQL5\Include\DoEasy\Services\MouseState.mqh.

ButtKeyState() wird in ButtonKeyState() umbenannt:

//--- Return (1-2) the cursor coordinates, (3) scroll wheel value, (4) status of the mouse buttons and Shift/Ctrl keys
   int               CoordX(void)                        const { return this.m_coord_x;            }

   int               DeltaWheel(void)                    const { return this.m_delta_wheel;        }
   ENUM_MOUSE_BUTT_KEY_STATE ButtonKeyState(const int id,const long lparam,const double dparam,const string flags);

...

   return (ENUM_MOUSE_BUTT_KEY_STATE)this.m_state_flags;
  }

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:

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 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:

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:

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:

//+------------------------------------------------------------------+

void CForm::OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam)

//+------------------------------------------------------------------+

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:

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:

Schreiben wir ihre Implementierung außerhalb des Klassenkörpers:

//+------------------------------------------------------------------+
//| Set the flags of mouse scrolling,                                |

   ::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
  {

   CListObj          m_list_all_canv_elm_obj;   // List of all graphical elements on canvas

   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);

   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                                                    |

            if(form!=NULL)
              {
               //--- disable moving the chart with a mouse, the chart context menu and the crosshairs tool

           }
        }
     }
  }
//+------------------------------------------------------------------+

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 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.

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.
