内容
概念
前回の記事で、ターミナル標準グラフィカルオブジェクトの抽象クラスを作成しました。クラスオブジェクトでは、すべてのグラフィカルオブジェクトに共通のプロパティを記述します。つまり、それは単にある種のグラフィカルオブジェクトです。実際のグラフィカルオブジェクトとの関係を明確にするには、この特定のグラフィカルオブジェクトに固有のプロパティを子孫オブジェクトクラスに設定する必要があります。反対に、他のいくつかのプロパティへのアクセスは、この特定のグラフィカルオブジェクトのパラメータではなく、抽象オブジェクトプロパティのセットに存在するため、制限する必要があります。
オブジェクトを構築するというこの概念は、ほとんどすべてのライブラリオブジェクトで受け入れられています。グラフィカルオブジェクトクラスも例外ではありません。
グラフィカルオブジェクトのグループとのオブジェクトの所属を指定するには、ターミナルから標準のグラフィカルオブジェクトグループのセットを使用し、新しいプロパティを抽象グラフィカルオブジェクトに追加します。これは、子孫クラスによって記述されたグラフィカルオブジェクトが属するグループです。
現在の記事では、Lines、Channels、Gann、Fibo、Elliottグループに属するオブジェクトクラスを作成します。残りのオブジェクトグループは、次の記事で紹介します。その背後にある理由は、これらのオブジェクトのすべてのプロパティが既存の抽象的なグラフィカルオブジェクト機能を使用して記述できるわけではないということです。したがって、ここでは、前の記事で作成したクラスの機能を使用して実装します。次の記事では、すべてのオブジェクトプロパティを読み書きする機能を追加し、残りのグラフィカルオブジェクトグループのクラスを実装します。
たとえば、グラフィカルオブジェクトのアンカーポイントが含まれます。抽象グラフィカルオブジェクトに格納されているプロパティは、オブジェクトプロパティ配列に格納されます。各配列フィールドは、時間などの単一のプロパティを記述します。デフォルトでは、時間はグラフィカルオブジェクトの最初のアンカーポイントから取得されます。他のすべてのアンカーポイントは、プロパティ修飾子を使用して必要なポイントのインデックスを指定することにより、 ObjectGetInteger()関数から取得できます。私が現在検討しているクラスは、1つの値しか保存できません。たとえば、同じタイプのプロパティの配列を作成し、プロパティ修飾子を使用する場合と同じ方法で必要なプロパティにアクセスする必要があります。
記事が限られているので、開発をいくつかの段階に分けます。
ライブラリクラスの改善
\MQL5\Include\DoEasy\Defines.mqhに、標準のグラフィカルオブジェクトグループの列挙を追加します。

グラフィカルオブジェクトはOBJPROP_TIMEFRAMES整数プロパティを備えており、任意の時間枠でオブジェクト画像を設定および受信できます。オブジェクトが表示されるチャートの時間枠は、オブジェクトの可視性フラグの組み合わせで定義または設定できます。
グラフィカルオブジェクトに設定された可視性フラグの説明を表示するには、サービス関数のファイル(\MQL5\Include\DoEasy\Services\DELib.mqh)に、要求された時間枠の有効/無効フラグステータスを返す関数を追加します。
//+------------------------------------------------------------------+ //| 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); } //+------------------------------------------------------------------+
関数に渡された値にすべての時間枠のフラグ(OBJ_ALL_PERIODS)が含まれている場合、オブジェクトはすべての時間枠で明確に表示され、フラグをチェックせずにすぐにtrue を返します。
すべての時間枠のすべてのフラグが無効になっている場合(OBJ_NO_PERIODS)、オブジェクトはすべての時間枠で完全に非表示になります。すぐにfalseを返します。
次に、関数に渡される時間枠の値に応じて、flags変数のビットを比較するflag変数に適切な値を割り当てます 。ビットマスクを受け取った後、その値をflags変数にビットマスクを課したときに得られた値と比較し、このビット単位の比較の結果を返します。この関数は、 flags変数がマスクによってチェックされたビットを特徴とする場合にのみtrueを返します。
グラフィカルオブジェクトのグループを定義しました。次に、この新しい値をグラフィカルオブジェクトのプロパティに追加しましょう。
すべてのライブラリグラフィカルオブジェクトの基本オブジェクトのファイル\MQL5\Include\DoEasy\Objects\Graph\GBaseObj.mqhのprotectedセクション内で、グラフィカルオブジェクトグループを格納するための変数を宣言します。
//+------------------------------------------------------------------+ //| 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
クラスのpublicセクションで、グラフィカルオブジェクトグループを設定するためのメソッドを設定します。
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; }
およびグループを返すメソッドを設定します。
//--- 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; }
指定された時間枠でオブジェクトの可視性フラグを返す以前に実装されたメソッドは、クラスのpublicセクションから削除されます。
//--- 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); }
これは最適ではありませんし、私はすでに上記で実装したサービス関数が同じことをします。
次に、グラフィカルオブジェクトグループの説明を返すメソッドを宣言します。
//--- 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(){;} }; //+------------------------------------------------------------------+
クラス本体の外側で実装しましょう。
//+------------------------------------------------------------------+ //| 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_GRAPHICAL) : "Unknown" ); } //+------------------------------------------------------------------+
ここではすべてが簡単です。m_groupで設定され、Group()メソッドによって返される値に応じて、適切なテキストメッセージを返します。
\MQL5\Include\DoEasy\Objects\Graph\Standart\GStdGraphObj.mqhの抽象グラフィカルオブジェクトクラスを改善しましょう。
一部のオブジェクトプロパティはオブジェクトごとに異なるため、これらのプロパティを返すメソッドの実装も異なる必要があります。このようなプロパティには、抽象グラフィカルオブジェクトクラスに共通の実装を持つ仮想メソッドが必要です。子孫オブジェクトの場合、この実装は子孫クラスで再定義されます。
クラスのpublicセクションで、3つの仮想メソッドを追加して、グラフィカルオブジェクトタイプの説明と、オブジェクトの最初のアンカーポイントの価格と時刻を返します。
//--- 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
子孫オブジェクトによって記述された特定のグラフィカルオブジェクトにデータを表示するために、子孫オブジェクトのメソッドを再定義します。
protectedパラメトリッククラスコンストラクタで、新しい仮パラメータを追加します(標準のグラフィカルオブジェクトグループ)。デフォルトのコンストラクタはすぐにグループ値-1を受け取ります。

オブジェクト文字列プロパティの説明を返すメソッドの場合、表示された文字列プロパティを囲む引用符の表示を追加します。ツールチップを説明するには、ツールチップが設定されておらず、ツールチップを無効にする「\n」制御記号でない場合、ツールチップがターミナルによって自動的に形成されるというメッセージを表示します。

以下は、時間枠でのオブジェクトの可視性の説明を返すメソッドです。
//+------------------------------------------------------------------+ //| 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; } //+------------------------------------------------------------------+
ここでは、オブジェクトプロパティから時間枠でのオブジェクトの可視性のビットフラグを取得します。
フラグが設定されていない場合は、オブジェクトがすべての時間枠で非表示になっていることを通知するメッセージを返します。
逆に、すべての時間枠のすべてのフラグが設定されている場合は、オブジェクトがすべての時間枠で表示されるというメッセージを返します。
一部のフラグのみが設定されている場合、1から21までのループで、私はずっと前に実装してサービス関数ファイルに配置したTimeframeByEnumIndex()サービス関数を使用して、インデックスで時間枠を取得します。
受信した時間枠でオブジェクトが表示されない場合は、次の反復に進みます次の時間枠を取得します。
オブジェクトが表示されたら、その簡単な説明をres変数値に追加し、最後にカンマとスペースを追加します。
ループが完了すると、結果の文字列の末尾のコンマをスペースに置き換え、文字列の右側にあるすべてのスペースと制御記号を削除します。結果の文字列がメソッドから返されます。
これで、クラスの改善はすべて終了しました。次に、抽象グラフィカルオブジェクトクラスの子孫クラスを作成します。
抽象グラフィカルオブジェクトの子孫オブジェクト
現在の記事では、Lines、Channels、Gann、Fibo、Elliottグループに属するオブジェクトクラスを作成します。
\MQL5\Include\DoEasy\Objects\Graph\Standart\に、StdHLineObj水平線クラスの新しいファイル GStdHLineObj.mqhを作成します。
クラスは抽象グラフィカルオブジェクトから派生する必要がありますが、親クラスファイル自体は作成されたクラスに接続されている必要があります。
//+------------------------------------------------------------------+ //| 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 { }
クラスのpublicセクションで、コンストラクタを追加し、オブジェクトでサポートされているプロパティのフラグを返す3つのメソッドと、オブジェクトの説明とプロパティを表示するメソッドを宣言します。
//+------------------------------------------------------------------+ //| "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); } }; //+------------------------------------------------------------------+
メソッドの目的は、名前から明確にする必要があります。その上、私は他のクラスで同様のメソッドを何度も検討しました。
クラスコンストラクタの初期化リストで、オブジェクトタイプ(水平線)を親クラスのクローズドパラメトリックコンストラクタに渡します。所属 - プログラムに属さない、オブジェクトグループ — 行、チャートIDとオブジェクト名の値がクラスコンストラクタに渡されます。
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) {}
TypeDescription()仮想メソッドは、以前に導入されたStdGraphObjectTypeDescription()サービス関数によって返されるグラフィカルオブジェクトの説明を返します。このサービス関数は、オブジェクトタイプ(水平線)を受け取ります。
virtual string TypeDescription(void) const { return StdGraphObjectTypeDescription(OBJ_HLINE); }
TimeDescription()仮想メソッドは、時間の説明を返し、水平線のプロパティで設定された時間を表示します。水平線には時間参照がないため、オブジェクトを配置しているときにグラフをクリックすると、マウスカーソルの座標がプロパティに入力されます。適切な追加メッセージが操作ログに表示される時間の説明に表示されます。
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); }
以下は、integer、real、stringプロパティのオブジェクトサポートを示すフラグを返すメソッドです。
//+------------------------------------------------------------------+ //| 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; } //+------------------------------------------------------------------+
プロパティは各メソッドに渡されます。次に、そのようなプロパティがサポートされているプロパティのリストにある場合はtrueを返し、それ以外の場合はfalseを返します。
グラフィカルオブジェクトはそれぞれ独自のプロパティセットを備えているため、サポートされるプロパティのリストはクラスごとに異なります。クラスコンストラクタは、抽象グラフィカルオブジェクトの子孫オブジェクトごとにも一意です。
以下は、短いオブジェクト名を表示するメソッドと短いオブジェクトの説明を操作ログに送信するメソッドです。
//+------------------------------------------------------------------+ //| 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) ); } //+------------------------------------------------------------------+
これらのメソッドは、(1)グラフィカルオブジェクトタイプを説明する文字列を返し、(2)グラフィカルオブジェクトタイプ、その名前、割り当てられたID、オブジェクトの作成時間を操作ログに表示します。
さまざまなタイプのグラフィカルオブジェクトを記述し、さまざまなグループに含まれる他のすべてのクラスについて、以下で詳しく説明します。
以下は、\MQL5\Include\DoEasy\Objects\Graph\Standart\GStdVLineObj.mqhにある「垂直線」オブジェクトクラスです。

今日計画されている抽象グラフィカルオブジェクトの子孫クラスのオブジェクトはこれらはすべてです。ご覧のとおり、これらは互いに同一ですが、サポートされているプロパティのタイプが異なります。つまり、各オブジェクトには固有のプロパティのみがあります。データは操作ログに表示されるだけではありません。最も重要なことは、ライブラリオブジェクトの検索と並べ替えでは、オブジェクトが特定のプロパティをサポートしていることを示すフラグが考慮されることです。したがって、コレクション内のすべてのグラフィカルオブジェクトを角度などで並べ替える場合、そのようなプロパティはサポートされていないため、最終的なリストにはコーナーのないオブジェクトは含まれません。
上記のクラスはすべて、独立した分析のために残しておきます。
次に、\MQL5\Include\DoEasy\Collections\GraphElementsCollection.mqhのグラフィカルオブジェクトコレクションクラスのファイルにあるチャートオブジェクト管理クラスを改善する必要があります。
チャートに追加されたグラフィカルオブジェクトに応じて、ここで作成したものから標準のグラフィカルオブジェクトクラスの新しいインスタンスが作成されます。ファイルに必要な改善を加えましょう。
ここで作成したすべてのクラスのファイルをグラフィカルオブジェクトコレクションクラスのファイルに含めます(以前に含めたGStdGraphObj.mqhの代わりに)チャートに追加された新しいグラフィカルオブジェクトオブジェクトを作成するためのpublicメソッドを宣言します。

このメソッドでは、グラフィカルオブジェクト管理クラスのチャート上のオブジェクト数の変化をチェックし、チャートに追加されたグラフィカルオブジェクトを説明する新しいオブジェクトを作成するためのコードブロックを改善します。

以前に、新しい抽象グラフィカルオブジェクトを作成しました。ここで開発した子孫クラスを使用して、適切なタイプのオブジェクトを作成します。オブジェクトが正常に作成されたら、所属プロパティをオブジェクトに追加します(プログラムに属していない)。操作ログは、作成されたオブジェクトの簡単な説明を表示する代わりに、そのすべてのプロパティの完全な説明を表示します。
作成するオブジェクトを選択するには、メソッドを使用して新しい標準のグラフィカルオブジェクトを作成します。

ここではすべてが簡単です。このメソッドは、作成するオブジェクトのタイプ、グラフィカルオブジェクトが追加されたチャートのID、および新しいグラフィカルオブジェクトの名前を受け取ります。次に、メソッドに渡されるグラフィカルオブジェクトのタイプに応じて、new演算子を使用して、抽象グラフィカルオブジェクトの適切な子孫クラスの新しいオブジェクトを作成し、新しいオブジェクトの作成結果をすぐに返します。
このメソッドは、新しく作成されたオブジェクトへのポインタを返すか、オブジェクト作成エラーの場合は NULL を返します。ご覧のとおり、まだすべてのオブジェクトが作成されているわけではありません。残りのものは、現在の記事で作成されたクラスに導入された改善とともに、次の記事で作成されます。最初のオブジェクトアンカーポイントではなく、すべてのオブジェクトアンカーポイントのすべてのプロパティへのアクセスを提供する必要があります。
すべてをテストする準備ができています。
検証
テストを実行するには、前の記事のEAを使用して、\MQL5\Experts\TestDoEasy\Part84\にTestDoEasyPart84.mq5として保存します。
現在、EAを変更する必要はありません。しかし、整理するのために、ターミナルフォルダの対応する記事に保存しました。
EAをコンパイルし、ターミナルで起動して、チャートにいくつかのグラフィカルオブジェクトを追加します。
オブジェクトチャートに追加されたすべてのプロパティの完全な説明は、操作ログに表示されます。
次の段階
次の記事では、抽象グラフィカルオブジェクトの子孫クラスとグラフィカルライブラリオブジェクトのコレクションクラスの開発を続けます。
