Konzept
Im vorigen Artikel habe ich die Klasse des abstrakten grafischen Standardobjekts Terminal erstellt. Das Klassenobjekt beschreibt die Eigenschaften, die allen grafischen Objekten gemeinsam sind. Es ist also einfach eine Art grafisches Objekt. Um seine Zugehörigkeit zu einem realen grafischen Objekt zu verdeutlichen, müssen wir die Eigenschaften, die diesem speziellen grafischen Objekt eigen sind, in der Klasse des Nachfolgeobjekts festlegen. Im Gegenteil, der Zugriff auf einige andere Eigenschaften sollte eingeschränkt werden, da sie nicht zu den Parametern dieses speziellen grafischen Objekts gehören, sondern in der Menge der abstrakten Objekteigenschaften enthalten sind.
Dieses Konzept der Objektbildung wird für fast alle Bibliotheksobjekte akzeptiert. Die grafischen Objektklassen bilden da keine Ausnahme.
Um die Zugehörigkeit des Objekts zu einer Gruppe von grafischen Objekten zu spezifizieren, verwenden wir eine Reihe von Standardgruppen für grafische Objekte aus dem Terminal und fügen dem abstrakten grafischen Objekt eine neue Eigenschaft hinzu — die Gruppe, zu der das grafische Objekt gehört, das durch die Nachfolgeklasse beschrieben wird:
In diesem Artikel werde ich Objektklassen erstellen, die zu den Gruppen Linien, Kanäle, Gann, Fibo und Elliott gehören. Die übrigen Objektgruppen werden im nächsten Artikel vorgestellt. Der Grund dafür ist, dass nicht alle Eigenschaften dieser Objekte mit der bestehenden abstrakten grafischen Objektfunktionalität beschrieben werden können. Daher werde ich hier die Funktionalität der im vorherigen Artikel erstellten Klasse verwenden. Im nächsten Artikel werde ich die Möglichkeit hinzufügen, alle Objekteigenschaften zu lesen und zu schreiben, sowie die Klassen der übrigen grafischen Objektgruppen implementieren.
Dazu gehören zum Beispiel die Ankerpunkte der grafischen Objekte. Die im abstrakten grafischen Objekt gespeicherten Eigenschaften werden in den Arrays der Objekteigenschaften gespeichert, wobei jedes Array-Feld eine einzelne Eigenschaft beschreibt, zum Beispiel die Zeit. Standardmäßig wird die Zeit dem ersten Ankerpunkt des grafischen Objekts entnommen. Alle anderen Ankerpunkte können über die Funktion ObjectGetInteger() abgerufen werden, indem der Index des erforderlichen Punktes über den Eigenschaftsmodifikator angegeben wird. Die Klasse, die ich derzeit in Betracht ziehe, kann nur einen Wert speichern. So sollten wir ein Array gleichartiger Eigenschaften erstellen und auf die erforderlichen Eigenschaften auf die gleiche Weise zugreifen, wie wenn wir einen Eigenschaftsmodifikator verwenden.
Da der Artikel begrenzt ist, werde ich die Entwicklung in mehrere Phasen unterteilen.
Verbesserung der Klassenbibliothek
In \MQL5\Include\DoEasy\Defines.mqh fügen wir die Enumeration der grafischen Standardobjektgruppen hinzu:
//+------------------------------------------------------------------+ //| The list of graphical element types | //+------------------------------------------------------------------+ enum ENUM_GRAPH_ELEMENT_TYPE { GRAPH_ELEMENT_TYPE_STANDART, // Standard graphical object GRAPH_ELEMENT_TYPE_ELEMENT, // Element GRAPH_ELEMENT_TYPE_SHADOW_OBJ, // Shadow object GRAPH_ELEMENT_TYPE_FORM, // Form GRAPH_ELEMENT_TYPE_WINDOW, // Window }; //+------------------------------------------------------------------+ //| Graphical object group | //+------------------------------------------------------------------+ enum ENUM_GRAPH_OBJ_GROUP { GRAPH_OBJ_GROUP_LINES, // Lines GRAPH_OBJ_GROUP_CHANNELS, // Channels GRAPH_OBJ_GROUP_GANN, // Gann GRAPH_OBJ_GROUP_FIBO, // Fibo GRAPH_OBJ_GROUP_ELLIOTT, // Elliott GRAPH_OBJ_GROUP_SHAPES, // Shapes GRAPH_OBJ_GROUP_ARROWS, // Arrows GRAPH_OBJ_GROUP_GRAPHICAL, // Graphical objects }; //+------------------------------------------------------------------+ //| Integer properties of a standard graphical object | //+------------------------------------------------------------------+
Fügen wir eine neue Eigenschaft zur Liste der ganzzahligen Objekteigenschaften hinzu und erhöhen die Anzahl der ganzzahligen Eigenschaften um 1 (von 51 auf 52):

Das grafische Objekt verfügt über die Integer-Eigenschaft OBJPROP_TIMEFRAMES, die es uns ermöglicht, das Objektbild in beliebigen Zeitrahmen zu setzen und zu empfangen. Die Zeitrahmen, in denen das Objekt angezeigt wird, können durch eine Kombination von Objektsichtbarkeitsflags definiert oder gesetzt werden.
Um die Beschreibung der für das grafische Objekt gesetzten Sichtbarkeitsflags anzuzeigen, fügen wir in der Datei der Servicefunktionen \MQL5\Include\DoEasy\Services\DELib.mqh die Funktion hinzu, die den Status des aktivierten/deaktivierten Flags für einen angeforderten Zeitrahmen zurückgibt:
//+------------------------------------------------------------------+ //| Return the flag of displaying the graphical | //| object on a specified chart timeframe | //+------------------------------------------------------------------+ bool IsVisibleOnTimeframe(const ENUM_TIMEFRAMES timeframe,const int flags) { if(flags==OBJ_ALL_PERIODS) return true; if(flags==OBJ_NO_PERIODS) return false; int flag=0; switch((int)timeframe) { case PERIOD_M1 : flag=0x00000001; break; case PERIOD_M2 : flag=0x00000002; break; case PERIOD_M3 : flag=0x00000004; break; case PERIOD_M4 : flag=0x00000008; break; case PERIOD_M5 : flag=0x00000010; break; case PERIOD_M6 : flag=0x00000020; break; case PERIOD_M10 : flag=0x00000040; break; case PERIOD_M12 : flag=0x00000080; break; case PERIOD_M15 : flag=0x00000100; break; case PERIOD_M20 : flag=0x00000200; break; case PERIOD_M30 : flag=0x00000400; break; case PERIOD_H1 : flag=0x00000800; break; case PERIOD_H2 : flag=0x00001000; break; case PERIOD_H3 : flag=0x00002000; break; case PERIOD_H4 : flag=0x00004000; break; case PERIOD_H6 : flag=0x00008000; break; case PERIOD_H8 : flag=0x00010000; break; case PERIOD_H12 : flag=0x00020000; break; case PERIOD_D1 : flag=0x00040000; break; case PERIOD_W1 : flag=0x00080000; break; case PERIOD_MN1 : flag=0x00100000; break; default: break; } return((flags & flag)==flag); } //+------------------------------------------------------------------+
Wenn der an die Funktion übergebene Wert die Flags aller Zeitrahmen enthält (OBJ_ALL_PERIODS), ist das Objekt auf allen Timeframes deutlich sichtbar und wir geben sofort true ohne Überprüfung der Flags zurück.
Wenn alle Flags aller Zeitrahmen deaktiviert sind (OBJ_NO_PERIODS), wird das Objekt in allen Timeframes komplett ausgeblendet. Es wird sofort false zurückgegeben.
Als Nächstes wird der Variablen Flag je nach dem an die Funktion übergebenen Zeitrahmenwert ein entsprechender Wert zugewiesen, mit dem die Bits der Variable flags verglichen werden sollen. Nach Erhalt einer Bitmaske wird ihr Wert mit dem Wert verglichen, den man erhält, wenn man der Variablen 'flags' eine Bitmaske auferlegt und das Ergebnis dieses bitweisen Vergleichs zurückgibt. Die Funktion gibt nur dann wahr zurück, wenn die Variable 'flags' das von der Maske geprüfte Bit enthält.
Ich habe die Gruppen von grafischen Objekten definiert. Fügen wir nun diesen neuen Wert zu den Eigenschaften der grafischen Objekte hinzu.
In der Datei des Basisobjekts aller grafischen Objekte der Bibliothek \MQL5\Include\DoEasy\Objects\Graph\GBaseObj.mqh (in ihrem geschützten Abschnitt), deklarieren wir die Variable zum Speichern der grafischen Objektgruppe:
//+------------------------------------------------------------------+ //| Class of the base object of the library graphical objects | //+------------------------------------------------------------------+ class CGBaseObj : public CObject { private: protected: ENUM_OBJECT m_type_graph_obj; // Graphical object type ENUM_GRAPH_ELEMENT_TYPE m_type_element; // Graphical element type ENUM_GRAPH_OBJ_BELONG m_belong; // Program affiliation ENUM_GRAPH_OBJ_GROUP m_group; // Graphical object group string m_name_prefix; // Object name prefix string m_name; // Object name long m_chart_id; // Object chart ID long m_object_id; // Object ID long m_zorder; // Priority of a graphical object for receiving the mouse click event int m_subwindow; // Subwindow index int m_shift_y; // Subwindow Y coordinate shift int m_type; // Object type int m_timeframes_visible; // Visibility of an object on timeframes (a set of flags) int m_digits; // Number of decimal places in a quote bool m_visible; // Object visibility bool m_back; // "Background object" flag bool m_selected; // "Object selection" flag bool m_selectable; // "Object availability" flag bool m_hidden; // "Disable displaying the name of a graphical object in the terminal object list" flag datetime m_create_time; // Object creation time
Wir setzen im öffentlichen Teil der Klasse die Methode zum Setzen der grafischen Objektgruppe:
public: //--- Set the values of the class variables void SetObjectID(const long value) { this.m_object_id=value; } void SetBelong(const ENUM_GRAPH_OBJ_BELONG belong){ this.m_belong=belong; } void SetTypeGraphObject(const ENUM_OBJECT obj) { this.m_type_graph_obj=obj; } void SetTypeElement(const ENUM_GRAPH_ELEMENT_TYPE type) { this.m_type_element=type;} void SetGroup(const ENUM_GRAPH_OBJ_GROUP group){ this.m_group=group; } void SetName(const string name) { this.m_name=name; } void SetChartID(const long chart_id) { this.m_chart_id=chart_id; } void SetDigits(const int value) { this.m_digits=value; }
und die Methode zur Rückgabe der Gruppe:
//--- Return the values of class variables ENUM_GRAPH_ELEMENT_TYPE TypeGraphElement(void) const { return this.m_type_element; } ENUM_GRAPH_OBJ_BELONG Belong(void) const { return this.m_belong; } ENUM_GRAPH_OBJ_GROUP Group(void) const { return this.m_group; } ENUM_OBJECT TypeGraphObject(void) const { return this.m_type_graph_obj; } datetime TimeCreate(void) const { return this.m_create_time; } string Name(void) const { return this.m_name; } long ChartID(void) const { return this.m_chart_id; } long ObjectID(void) const { return this.m_object_id; } long Zorder(void) const { return this.m_zorder; } int SubWindow(void) const { return this.m_subwindow; } int ShiftY(void) const { return this.m_shift_y; } int VisibleOnTimeframes(void) const { return this.m_timeframes_visible; } int Digits(void) const { return this.m_digits; } bool IsBack(void) const { return this.m_back; } bool IsSelected(void) const { return this.m_selected; } bool IsSelectable(void) const { return this.m_selectable; } bool IsHidden(void) const { return this.m_hidden; } bool IsVisible(void) const { return this.m_visible; }
Die zuvor implementierte Methode, die das Sichtbarkeitskennzeichen des Objekts für den angegebenen Zeitrahmen zurückgibt, wurde aus dem öffentlichen Klassenteil entfernt:
//--- Return the object visibility flag on a specified timeframe bool IsVisibleOnTimeframe(const ENUM_TIMEFRAMES timeframe) const { return((this.m_timeframes_visible & timeframe)==timeframe); } //--- Return the graphical object type (ENUM_OBJECT) calculated from the object type (ENUM_OBJECT_DE_TYPE) passed to the method ENUM_OBJECT GraphObjectType(const ENUM_OBJECT_DE_TYPE obj_type) const { return ENUM_OBJECT(obj_type-OBJECT_DE_TYPE_GSTD_OBJ-1); }
Erstens ist es nicht optimal. Zweitens habe ich bereits die obige Dienstfunktion implementiert, die das Gleiche tut.
Als Nächstes deklarieren wir die Methode, die die Beschreibung der grafischen Objektgruppe zurückgibt:
//--- Return the graphical object type (ENUM_OBJECT) calculated from the object type (ENUM_OBJECT_DE_TYPE) passed to the method ENUM_OBJECT GraphObjectType(const ENUM_OBJECT_DE_TYPE obj_type) const { return ENUM_OBJECT(obj_type-OBJECT_DE_TYPE_GSTD_OBJ-1); } //--- Return the description of the type of the graphical object (1) type, (2) element, (3) affiliation and (4) group string TypeGraphObjectDescription(void); string TypeElementDescription(void); string BelongDescription(void); string GroupDescription(void); //--- The virtual method returning the object type virtual int Type(void) const { return this.m_type; } //--- Constructor/destructor CGBaseObj(); ~CGBaseObj(){;} }; //+------------------------------------------------------------------+
Schreiben wir seine Implementierung außerhalb des Klassenkörpers:
//+------------------------------------------------------------------+ //| Return the description of the graphical object group | //+------------------------------------------------------------------+ string CGBaseObj::GroupDescription(void) { return ( this.Group()==GRAPH_OBJ_GROUP_LINES ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_LINES) : this.Group()==GRAPH_OBJ_GROUP_CHANNELS ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_CHANNELS) : this.Group()==GRAPH_OBJ_GROUP_GANN ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_GANN) : this.Group()==GRAPH_OBJ_GROUP_FIBO ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_FIBO) : this.Group()==GRAPH_OBJ_GROUP_ELLIOTT ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_ELLIOTT) : this.Group()==GRAPH_OBJ_GROUP_SHAPES ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_SHAPES) : this.Group()==GRAPH_OBJ_GROUP_ARROWS ? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_ARROWS) : this.Group()==GRAPH_OBJ_GROUP_GRAPHICAL? CMessage::Text(MSG_GRAPH_OBJ_PROP_GROUP_GRAPHICAL) : "Unknown" ); } //+------------------------------------------------------------------+
Hier ist alles einfach. Je nach dem in m_group eingestellten und von der Methode Group() zurückgegebenen Wert wird die entsprechende Textmeldung zurückgegeben.
Verbessern wir die abstrakte grafische Objektklasse in \MQL5\Include\DoEasy\Objects\Graph\Standart\GStdGraphObj.mqh.
Da einige Objekteigenschaften für verschiedene Objekte unterschiedlich sind, sollte auch die Implementierung der Methoden, die diese Eigenschaften zurückgeben, unterschiedlich sein. Solche Eigenschaften sollten virtuelle Methoden mit einer gemeinsamen Implementierung in der abstrakten grafischen Objektklasse haben. Für Nachfolgeobjekte wird diese Implementierung in der Nachfolgeklasse neu definiert.
Fügen Sie im öffentlichen Teil der Klasse drei virtuelle Methoden hinzu, die die Beschreibungen des grafischen Objekttyps sowie den Preis und die Zeit des ersten Ankerpunkts des Objekts zurückgeben:
//--- Display the description of the object properties in the journal (full_prop=true - all properties, false - supported ones only - implemented in descendant classes) virtual void Print(const bool full_prop=false,const bool dash=false); //--- Display a short description of the object in the journal virtual void PrintShort(const bool dash=false,const bool symbol=false); //--- Return the object short name virtual string Header(const bool symbol=false); //--- Return the description of the graphical object (1) type (ENUM_OBJECT), price coordinate (2) and (3) time virtual string TypeDescription(void) const { return CMessage::Text(MSG_GRAPH_STD_OBJ_ANY); } virtual string PriceDescription(void) const { return ::DoubleToString(this.GetProperty(GRAPH_OBJ_PROP_PRICE),this.m_digits); } virtual string TimeDescription(void) const { return ::TimeToString(this.GetProperty(GRAPH_OBJ_PROP_TIME),TIME_DATE|TIME_MINUTES); } //--- Compare CGStdGraphObj objects by a specified property (to sort the list by an object property) virtual int Compare(const CObject *node,const int mode=0) const; //--- Compare CGStdGraphObj objects with each other by all properties (to search for equal objects) bool IsEqual(CGStdGraphObj* compared_req) const; //--- Default constructor
Redefinieren wir die Methoden in den Nachfolgeobjekten zur Anzeige von Daten auf einem bestimmten grafischen Objekt, das durch das Nachfolgeobjekt beschrieben wird.
Im Konstruktor der geschützten parametrischen Klasse fügen wir einen neuen formalen Parameter hinzu — die Gruppe des grafischen Standardobjekts, während der Standardkonstruktor sofort den Gruppenwert -1 erhält:
//--- Default constructor CGStdGraphObj(){ this.m_type=OBJECT_DE_TYPE_GSTD_OBJ; m_group=WRONG_VALUE; } protected: //--- Protected parametric constructor CGStdGraphObj(const ENUM_OBJECT_DE_TYPE obj_type, const ENUM_GRAPH_OBJ_BELONG belong, const ENUM_GRAPH_OBJ_GROUP group, const long chart_id, const string name); public: //+--------------------------------------------------------------------+ //|Methods of simplified access and setting graphical object properties| //+--------------------------------------------------------------------+
Ganz am Ende der Liste der Methoden für einen vereinfachten Zugriff auf die Klasseneigenschaften fügen wir die Methoden hinzu, die die Sichtbarkeitsflags des Objekts für einen bestimmten Zeitrahmen zurückgeben. Jeder Zeitrahmen soll seine eigene Methode haben. Deklaration der Methode, die die Beschreibung der Objektsichtbarkeit für alle Zeitrahmen zurückgibt:

//+------------------------------------------------------------------+ //| Return description of object's real property | //+------------------------------------------------------------------+ string CGStdGraphObj::GetPropertyDescription(ENUM_GRAPH_OBJ_PROP_DOUBLE property) { int dg=(this.m_digits>0 ? this.m_digits : 1); return ( property==GRAPH_OBJ_PROP_PRICE ?

Für die Methode, die die Beschreibung der String-Eigenschaft des Objekts zurückgibt, fügen wir die Anzeige von Anführungszeichen hinzu, die die angezeigten String-Eigenschaften einschließen. Zur Beschreibung eines Tooltips eine Meldung anzeigen, dass der Tooltip vom Terminal automatisch gebildet wird, wenn er nicht gesetzt ist und nicht das "\n" Steuersymbol ist, das den Tooltip deaktiviert:
//+------------------------------------------------------------------+ //| Return description of object's string property | //+------------------------------------------------------------------+ string CGStdGraphObj::GetPropertyDescription(ENUM_GRAPH_OBJ_PROP_STRING property) { return ( property==GRAPH_OBJ_PROP_NAME ? CMessage::Text(MSG_GRAPH_OBJ_PROP_NAME)+ (!this.SupportProperty(property) ?

": "+CMessage::Text(MSG_LIB_PROP_NOT_SUPPORTED) : ": "+this.GetProperty(property) ) : "" ); } //+------------------------------------------------------------------+
Die Methode, die die Beschreibung der Objektsichtbarkeit auf Zeitrahmen zurückgibt:
//+------------------------------------------------------------------+ //| Return the description of the object visibility on timeframes | //+------------------------------------------------------------------+ string CGStdGraphObj::VisibleOnTimeframeDescription(void) { string res=""; int flags=(int)this.GetProperty(GRAPH_OBJ_PROP_TIMEFRAMES); if(flags==OBJ_NO_PERIODS) return CMessage::Text(MSG_LIB_TEXT_OBJ_NO_PERIODS); if(flags==OBJ_ALL_PERIODS) return CMessage::Text(MSG_LIB_TEXT_OBJ_ALL_PERIODS); for(int i=1;i<=21;i++) { ENUM_TIMEFRAMES timeframe=TimeframeByEnumIndex((uchar)i); if(!IsVisibleOnTimeframe(timeframe,flags)) continue; res+=TimeframeDescription(timeframe)+", "; } ::StringSetCharacter(res,::StringLen(res)-2,' '); ::StringTrimRight(res); return res; } //+------------------------------------------------------------------+
Hier erhalten wir die Bitflags der Objektsichtbarkeit auf Zeitrahmen aus der Objekteigenschaft.
Wenn keines der Flags gesetzt ist, wird die Meldung zurückgegeben, dass das Objekt in jedem einzelnen Zeitrahmen unsichtbar ist.
Wenn hingegen alle Flags aller Zeitrahmen gesetzt sind, wird die Meldung zurückgegeben, dass das Objekt in allen Zeitrahmen sichtbar ist.
Sind nur einige der Flags gesetzt, dann holen wir uns in der Schleife von 1 bis 21 den Zeitrahmen per Index mit der Servicefunktion TimeframeByEnumIndex(), die ich vor langer Zeit implementiert habe und die sich in der Servicefunktionsdatei befindet.
Wenn das Objekt in einem empfangenen Zeitrahmen unsichtbar ist, gehe weiter zur nächsten Iteration, um den nächsten Zeitrahmen zu erhalten.
Wenn wir das Objekt sehen können, fügen wir seine Kurzbeschreibung zum res Variablenwert hinzu, indem wir Komma und Leerzeichen am Ende hinzufügen.
Nach Abschluss der Schleife ersetzen wir das Komma am Ende der resultierenden Zeichenkette durch ein Leerzeichen und entfernen alle Leerzeichen und Steuerzeichen rechts von der Zeichenkette. Die resultierende Zeichenkette wird von der Methode zurückgegeben.
Alle Klassenverbesserungen sind abgeschlossen. Nun ist es an der Zeit, Nachfolgeklassen der abstrakten grafischen Objektklasse zu erstellen.
Abgeleitete Objekte des abstrakten grafischen Objekts
In diesem Artikel werde ich die Klassen mehrerer grafischer Objektgruppen erstellen: Linien, Kanäle, Gann, Fibo und Elliott.
In \MQL5\Include\DoEasy\Objects\Graph\Standart\ werde ich eine neue Datei GStdHLineObj.mqh der horizontalen Linienklasse StdHLineObj erstellen.
Die Klasse soll von dem abstrakten grafischen Objekt abgeleitet werden, während die übergeordnete Klassendatei selbst mit der erstellten Klasse verbunden werden soll:
//+------------------------------------------------------------------+ //| GStdHLineObj.mqh | //| Copyright 2021, MetaQuotes Ltd. | //| https://mql5.com/en/users/artmedia70 | //+------------------------------------------------------------------+ #property copyright "Copyright 2021, MetaQuotes Ltd." #property link "https://mql5.com/en/users/artmedia70" #property link "https://mql5.com/en/users/artmedia70" #property version "1.00" //+------------------------------------------------------------------+ //| Include files | //+------------------------------------------------------------------+ #include "GStdGraphObj.mqh" //+------------------------------------------------------------------+ //| "Horizontal line" graphical object | //+------------------------------------------------------------------+ class CGStdHLineObj : public CGStdGraphObj { }
Im öffentlichen Abschnitt der Klasse fügen wir den Konstruktor hinzu, deklarieren drei Methoden, die die Flags der vom Objekt unterstützten Eigenschaften zurückgeben, und die Methode zur Anzeige der Objektbeschreibungen und -eigenschaften:
//+------------------------------------------------------------------+ //| "Horizontal line" graphical object | //+------------------------------------------------------------------+ class CGStdHLineObj : public CGStdGraphObj { private: public: //--- Constructor CGStdHLineObj(const long chart_id,const string name) : CGStdGraphObj(OBJECT_DE_TYPE_GSTD_HLINE,GRAPH_OBJ_BELONG_NO_PROGRAM,GRAPH_OBJ_GROUP_LINES,chart_id,name) {} //--- Supported object properties (1) real, (2) integer virtual bool SupportProperty(ENUM_GRAPH_OBJ_PROP_DOUBLE property); virtual bool SupportProperty(ENUM_GRAPH_OBJ_PROP_INTEGER property); virtual bool SupportProperty(ENUM_GRAPH_OBJ_PROP_STRING property); //--- Display a short description of the object in the journal virtual void PrintShort(const bool dash=false,const bool symbol=false); //--- Return the object short name virtual string Header(const bool symbol=false); //--- Return the description of the graphical object price (1) type (ENUM_OBJECT) and (2) price coordinate virtual string TypeDescription(void) const { return StdGraphObjectTypeDescription(OBJ_HLINE); } virtual string TimeDescription(void) const { return ::TimeToString(this.GetProperty(GRAPH_OBJ_PROP_TIME),TIME_DATE|TIME_MINUTES)+" "+ CMessage::Text(MSG_GRAPH_OBJ_TEXT_CLICK_COORD); } }; //+------------------------------------------------------------------+
Der Zweck der Methoden sollte aus ihren Namen ersichtlich sein. Außerdem habe ich ähnliche Methoden in anderen Klassen oft in Betracht gezogen.
In der Initialisierungsliste des Klassenkonstruktors übergeben wir den Objekttyp — horizontale Linie an den geschlossenen parametrischen Konstruktor der Elternklasse, Zugehörigkeit — gehört nicht zum Programm, Objektgruppe — Zeilen sowie Chart-ID- und Objektnamenwerte, die an den Klassenkonstruktor übergeben werden:
CGStdHLineObj(const long chart_id,const string name) : CGStdGraphObj(OBJECT_DE_TYPE_GSTD_HLINE,GRAPH_OBJ_BELONG_NO_PROGRAM,GRAPH_OBJ_GROUP_LINES,chart_id,name) {}
Die virtuelle Methode TypeDescription() gibt die Beschreibung des grafischen Objekts zurück, das von der zuvor eingeführten Dienstfunktion StdGraphObjectTypeDescription() zurückgegeben wird, die den Objekttyp empfängt — horizontale Linie:
virtual string TypeDescription(void) const { return StdGraphObjectTypeDescription(OBJ_HLINE); }
Die virtuelle Methode TimeDescription(), die die Zeitbeschreibung zurückgibt, zeigt die in den Eigenschaften der horizontalen Linie eingestellte Zeit an. Da die horizontale Linie keinen Zeitbezug hat, wird die Koordinate des Mauszeigers in die Eigenschaft eingetragen, wenn man beim Platzieren des Objekts auf das Diagramm klickt. Die entsprechende Zusatzmeldung erscheint in der Zeitbeschreibung, die im Journal angezeigt wird:
virtual string TimeDescription(void) const { return ::TimeToString(this.GetProperty(GRAPH_OBJ_PROP_TIME),TIME_DATE|TIME_MINUTES)+" "+ CMessage::Text(MSG_GRAPH_OBJ_TEXT_CLICK_COORD); }
Die Methoden, die die Flags zurückgeben, die die Objektunterstützung für die Eigenschaften integer, real und string angeben:
//+------------------------------------------------------------------+ //| Return 'true' if an object supports a passed | //| integer property, otherwise return 'false' | //+------------------------------------------------------------------+ bool CGStdHLineObj::SupportProperty(ENUM_GRAPH_OBJ_PROP_INTEGER property) { switch((int)property) { //--- Supported properties case GRAPH_OBJ_PROP_ID : case GRAPH_OBJ_PROP_TYPE : case GRAPH_OBJ_PROP_ELEMENT_TYPE : case GRAPH_OBJ_PROP_GROUP : case GRAPH_OBJ_PROP_BELONG : case GRAPH_OBJ_PROP_CHART_ID : case GRAPH_OBJ_PROP_WND_NUM : case GRAPH_OBJ_PROP_NUM : case GRAPH_OBJ_PROP_CREATETIME : case GRAPH_OBJ_PROP_TIMEFRAMES : case GRAPH_OBJ_PROP_BACK : case GRAPH_OBJ_PROP_ZORDER : case GRAPH_OBJ_PROP_HIDDEN : case GRAPH_OBJ_PROP_SELECTED : case GRAPH_OBJ_PROP_SELECTABLE : case GRAPH_OBJ_PROP_TIME : case GRAPH_OBJ_PROP_COLOR : case GRAPH_OBJ_PROP_STYLE : case GRAPH_OBJ_PROP_WIDTH : return true; //--- Other properties are not supported //--- Default is 'false' default: break; } return false; } //+------------------------------------------------------------------+ //| Return 'true' if an object supports a passed | //| real property, otherwise return 'false' | //+------------------------------------------------------------------+ bool CGStdHLineObj::SupportProperty(ENUM_GRAPH_OBJ_PROP_DOUBLE property) { switch((int)property) { //--- Supported properties case GRAPH_OBJ_PROP_PRICE : return true; //--- Other properties are not supported //--- Default is 'false' default: break; } return false; } //+------------------------------------------------------------------+ //| Return 'true' if an object supports a passed | //| string property, otherwise return 'false' | //+------------------------------------------------------------------+ bool CGStdHLineObj::SupportProperty(ENUM_GRAPH_OBJ_PROP_STRING property) { switch((int)property) { //--- Supported properties case GRAPH_OBJ_PROP_NAME : case GRAPH_OBJ_PROP_TEXT : case GRAPH_OBJ_PROP_TOOLTIP : return true; //--- Other properties are not supported //--- Default is 'false' default: break; } return false; } //+------------------------------------------------------------------+
Die Eigenschaft wird an jede Methode übergeben. Dann, wenn eine solche Eigenschaft in der Liste der unterstützten Eigenschaften ist, wird true zurückgegeben, sonst — false.
Die Listen der unterstützten Eigenschaften sind für jede Klasse unterschiedlich, da jedes grafische Objekt seinen eigenen Satz an Eigenschaften besitzt. Auch die Klassenkonstruktoren sind für jedes von dem abstrakten grafischen Objekt abstammende Objekt eindeutig.
Die Methoden für die Anzeige des kurzen Objektnamens und des Sendens der kurzen Objektbeschreibung an das Journal:
//+------------------------------------------------------------------+ //| Return the object short name | //+------------------------------------------------------------------+ string CGStdHLineObj::Header(const bool symbol=false) { return this.TypeDescription(); } //+------------------------------------------------------------------+ //| Display a short description of the object in the journal | //+------------------------------------------------------------------+ void CGStdHLineObj::PrintShort(const bool dash=false,const bool symbol=false) { ::Print ( this.Header(symbol)," \"",CGBaseObj::Name(),"\": ID ",(string)this.GetProperty(GRAPH_OBJ_PROP_ID), " ",::TimeToString(CGBaseObj::TimeCreate(),TIME_DATE|TIME_MINUTES|TIME_SECONDS) ); } //+------------------------------------------------------------------+
Diese Methoden (1) geben eine Zeichenkette zurück, die den Typ des grafischen Objekts beschreibt, und (2) zeigen den Typ des grafischen Objekts sowie seinen Namen, die zugewiesene ID und die Erstellungszeit des Objekts im Journal an.
Alle anderen Klassen, die grafische Objekte unterschiedlichen Typs beschreiben und in verschiedenen Gruppen enthalten sind, werden im Folgenden ausführlich behandelt.

Dies sind alle Objekte der für heute geplanten abstrakten grafischen Objektnachfolgeklassen. Wie Sie sehen können, sind sie untereinander identisch, unterscheiden sich aber in den Arten der unterstützten Eigenschaften. Das bedeutet, dass jedes dieser Objekte nur die ihm innewohnenden Eigenschaften haben wird. Die Daten werden nicht nur im Journal angezeigt. Am wichtigsten ist, dass bei der Suche und Sortierung von Bibliotheksobjekten die Flaggen berücksichtigt werden, die anzeigen, dass das Objekt eine bestimmte Eigenschaft unterstützt. Wenn man also alle grafischen Objekte in der Sammlung zum Beispiel nach einem Winkel sortiert, wird die endgültige Liste keine Objekte enthalten, die keine Ecke haben, da eine solche Eigenschaft von ihnen nicht unterstützt wird.
Ich werde alle oben genannten Klassen für eine unabhängige Analyse belassen.
Nun müssen wir die Klasse für die Verwaltung von Diagrammobjekten verbessern, die sich in der Datei der Klasse für die Sammlung grafischer Objekte in \MQL5\Include\DoEasy\Collections\GraphElementsCollection.mqh befindet.
Abhängig von einem grafischen Objekt, das dem Diagramm hinzugefügt wird, soll eine neue Instanz der Standard-Grafikobjektklasse aus den von mir hier erstellten erstellt werden. Nehmen wir die notwendigen Verbesserungen an der Datei vor.
Wir fügen die Dateien aller hier erstellten Klassen in die Datei der Klasse der grafischen Objektsammlung ein (anstelle der zuvor eingefügten GStdGraphObj.mqh) und deklarieren die öffentliche Methode zum Erstellen eines neuen Objekts, das das zum Diagramm hinzugefügte grafische Objekt beschreibt:

In der Methode zur Überprüfung der Änderungen in der Anzahl der Objekte im Diagramm der Klasse für die Verwaltung von grafischen Objekten werden Verbesserungen im Codeblock für die Erstellung eines neuen Objekts vorgenommen, das ein zum Diagramm hinzugefügtes grafisches Objekt beschreibt:

Ich habe bereits früher ein neues abstraktes grafisches Objekt erstellt. Jetzt ist es an der Zeit, ein Objekt eines geeigneten Typs mit Hilfe der hier entwickelten Nachfolgeklassen zu erstellen. Nachdem das Objekt erfolgreich erstellt wurde, fügen wir ihm die Eigenschaft Zugehörigkeit hinzu (gehört nicht zum Programm). Statt der Kurzbeschreibung des erstellten Objekts zeigt das Journal die vollständige Beschreibung aller seiner Eigenschaften an.
Um das zu erstellende Objekt auszuwählen, verwenden wir die Methode zum Erstellen eines neuen grafischen Standardobjekts:
//+------------------------------------------------------------------+ //| Create a new standard graphical object | //+------------------------------------------------------------------+ CGStdGraphObj *CChartObjectsControl::CreateNewGraphObj(const ENUM_OBJECT obj_type,const long chart_id,const string name) { CGStdGraphObj *obj=NULL; switch((int)obj_type) { //--- Lines case OBJ_VLINE : return new CGStdVLineObj(chart_id,name); case OBJ_HLINE : return new CGStdHLineObj(chart_id,name); case OBJ_TREND : return new CGStdTrendObj(chart_id,name); case OBJ_TRENDBYANGLE : return new CGStdTrendByAngleObj(chart_id,name); case OBJ_CYCLES : return new CGStdCyclesObj(chart_id,name); case OBJ_ARROWED_LINE : return new CGStdArrowedLineObj(chart_id,name); //--- Channels case OBJ_CHANNEL : return new CGStdChannelObj(chart_id,name); case OBJ_STDDEVCHANNEL : return new CGStdStdDevChannelObj(chart_id,name); case OBJ_REGRESSION : return new CGStdRegressionObj(chart_id,name); case OBJ_PITCHFORK : return new CGStdPitchforkObj(chart_id,name); //--- Gann case OBJ_GANNLINE : return new CGStdGannLineObj(chart_id,name); case OBJ_GANNFAN : return new CGStdGannFanObj(chart_id,name); case OBJ_GANNGRID : return new CGStdGannGridObj(chart_id,name); //--- Fibo case OBJ_FIBO : return new CGStdFiboObj(chart_id,name); case OBJ_FIBOTIMES : return new CGStdFiboTimesObj(chart_id,name); case OBJ_FIBOFAN : return new CGStdFiboFanObj(chart_id,name); case OBJ_FIBOARC : return new CGStdFiboArcObj(chart_id,name); case OBJ_FIBOCHANNEL : return new CGStdFiboChannelObj(chart_id,name); case OBJ_EXPANSION : return new CGStdExpansionObj(chart_id,name); //--- Elliott case OBJ_ELLIOTWAVE5 : return new CGStdElliotWave5Obj(chart_id,name); case OBJ_ELLIOTWAVE3 : return new CGStdElliotWave3Obj(chart_id,name); /* //--- Shapes case OBJ_RECTANGLE : return new CGStdRectangleObj(chart_id,name); case OBJ_TRIANGLE : return new CGStdTriangleObj(chart_id,name); case OBJ_ELLIPSE : return new CGStdEllipseObj(chart_id,name); //--- Arrows case OBJ_ARROW_THUMB_UP : return new CGStdArrowThumbUpObj(chart_id,name); case OBJ_ARROW_THUMB_DOWN : return new CGStdArrowThumbDownObj(chart_id,name); case OBJ_ARROW_UP : return new CGStdArrowUpObj(chart_id,name); case OBJ_ARROW_DOWN : return new CGStdArrowDownObj(chart_id,name); case OBJ_ARROW_STOP : return new CGStdArrowStopObj(chart_id,name); case OBJ_ARROW_CHECK : return new CGStdArrowCheckObj(chart_id,name); case OBJ_ARROW_LEFT_PRICE : return new CGStdArrowLeftPriceObj(chart_id,name); case OBJ_ARROW_RIGHT_PRICE : return new CGStdArrowRightPriceObj(chart_id,name); case OBJ_ARROW_BUY : return new CGStdArrowBuyObj(chart_id,name); case OBJ_ARROW_SELL : return new CGStdArrowSellObj(chart_id,name); case OBJ_ARROW : return new CGStdArrowObj(chart_id,name); //--- Graphical objects case OBJ_TEXT : return new CGStdTextObj(chart_id,name); case OBJ_LABEL : return new CGStdLabelObj(chart_id,name); case OBJ_BUTTON : return new CGStdButtonObj(chart_id,name); case OBJ_CHART : return new CGStdChartObj(chart_id,name); case OBJ_BITMAP : return new CGStdBitmapObj(chart_id,name); case OBJ_BITMAP_LABEL : return new CGStdBitmapLabelObj(chart_id,name); case OBJ_EDIT : return new CGStdEditObj(chart_id,name); case OBJ_EVENT : return new CGStdEventObj(chart_id,name); case OBJ_RECTANGLE_LABEL : return new CGStdRectangleLabelObj(chart_id,name); */ default : return NULL; } } //+------------------------------------------------------------------+
Hier ist alles einfach. Die Methode erhält den Typ des zu erstellenden Objekts, die ID des Diagramms, dem das grafische Objekt hinzugefügt wurde, und den Namen des neuen grafischen Objekts. Anschließend wird je nach Typ des an die Methode übergebenen grafischen Objekts mit dem new operator ein neues Objekt der entsprechenden Nachfolgeklasse des abstrakten grafischen Objekts erstellt und das Ergebnis der Erstellung eines neuen Objekts sofort zurückgegeben.
Die Methode liefert entweder einen Zeiger auf ein neu erstelltes Objekt oder NULL im Falle eines Fehlers bei der Objekterstellung. Wie wir sehen können, sind noch nicht alle Objekte erstellt worden. Die verbleibenden werden im nächsten Artikel erstellt, zusammen mit den Verbesserungen, die in den im aktuellen Artikel erstellten Klassen eingeführt werden. Wir müssen den Zugriff auf alle Eigenschaften aller Objektankerpunkte ermöglichen und nicht nur auf den allerersten.
Alles ist bereit zum Testen.
Test
Um den Test durchzuführen, verwenden wir den EA aus dem vorherigen Artikel und speichern ihn in \MQL5\Experts\TestDoEasy\Part84\ als TestDoEasyPart84.mq5.
Änderungen im EA sind derzeit nicht erforderlich. Der Ordnung halber habe ich ihn aber im entsprechenden Artikel im Terminalordner gespeichert.
Kompilieren Sie den EA, starten Sie ihn im Terminal und fügen Sie einige grafische Objekte in den Chart ein.
Die vollständigen Beschreibungen aller Eigenschaften, die den Objektcharts hinzugefügt werden, sind im Journal zu finden:
Was kommt als Nächstes?
Im nächsten Artikel werde ich die Entwicklung von Nachfolgeklassen des abstrakten grafischen Objekts und der Sammelklasse von grafischen Bibliotheksobjekten fortsetzen.
Alle Dateien der aktuellen Version der Bibliothek sind unten zusammen mit der Test-EA-Datei für MQL5 zum Testen und Herunterladen angehängt.
