Concept
In the previous article, I created the class of the terminal abstract standard graphical object. The class object describes the properties that are common for all graphical objects. So, it is simply some kind of a graphical object. To clarify its affiliation with a real graphical object, we need to set the properties inherent in this particular graphical object in the descendant object class. On the contrary, access to some other properties should be limited since they are not the parameters of this particular graphical object but are present in the set of abstract object properties.
This concept of building objects is accepted for almost all library objects. The graphical object classes are no exception.
To specify the object affiliation with the group of graphical objects, we will use a set of standard graphical object groups from the terminal and add a new property to the abstract graphical object — the group the graphical object described by the descendant class belongs to:
In the current article, I am going to create object classes belonging to Lines, Channels, Gann, Fibo and Elliott groups. The remaining object groups will be introduced in the next article. The reason behind that is that not all properties of these objects can be described using the existing abstract graphical object functionality. Therefore, here I am going to implement things using the functionality of the class created in the previous article. In the next article, I will add the ability to read and write all object properties, as well as implement the classes of the remaining graphical object groups.
They include, for instance, graphical object anchor points. The properties stored in the abstract graphical object are stored in the object property arrays where each array field describes a single property, for example time. By default, the time is taken from the graphical object first anchor point. All other anchor points can be obtained from the ObjectGetInteger() function by specifying the index of the necessary point via the property modifier. The class I am currently considering is able to store one value only. For instance, we should create an array of same-type properties and access the necessary properties the same way as when using a property modifier.
Since the article is limited, I will divide the development into several stages.
Improving library classes
In \MQL5\Include\DoEasy\Defines.mqh, add the enumeration of standard graphical object groups:
//+------------------------------------------------------------------+ //| 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 | //+------------------------------------------------------------------+
Add a new property to the list of object integer properties and increase the number of integer properties by 1 (from 51 to 52):
//+------------------------------------------------------------------+ //| Integer properties of a standard graphical object | //+------------------------------------------------------------------+ enum ENUM_GRAPH_OBJ_PROP_INTEGER { //--- Additional properties GRAPH_OBJ_PROP_ID = 0, // Object ID GRAPH_OBJ_PROP_TYPE, // Graphical object type (ENUM_OBJECT) GRAPH_OBJ_PROP_ELEMENT_TYPE, // Graphical element type (ENUM_GRAPH_ELEMENT_TYPE) GRAPH_OBJ_PROP_GROUP, // Graphical object group (ENUM_GRAPH_OBJ_GROUP) GRAPH_OBJ_PROP_BELONG, // Graphical object affiliation GRAPH_OBJ_PROP_CHART_ID, // Chart ID GRAPH_OBJ_PROP_WND_NUM, // Chart subwindow index GRAPH_OBJ_PROP_NUM, // Object index in the list //--- Common properties of all graphical objects GRAPH_OBJ_PROP_CREATETIME, // Object creation time GRAPH_OBJ_PROP_TIMEFRAMES, // Object visibility on timeframes GRAPH_OBJ_PROP_BACK, // Background object GRAPH_OBJ_PROP_ZORDER, // Priority of a graphical object for receiving the event of clicking on a chart GRAPH_OBJ_PROP_HIDDEN, // Disable displaying the name of a graphical object in the terminal object list GRAPH_OBJ_PROP_SELECTED, // Object selection GRAPH_OBJ_PROP_SELECTABLE, // Object availability //--- Properties belonging to different graphical objects GRAPH_OBJ_PROP_TIME, // Time coordinate GRAPH_OBJ_PROP_COLOR, // Color GRAPH_OBJ_PROP_STYLE, // Style GRAPH_OBJ_PROP_WIDTH, // Line width GRAPH_OBJ_PROP_FILL, // Object color filling GRAPH_OBJ_PROP_READONLY, // Ability to edit text in the Edit object GRAPH_OBJ_PROP_LEVELS, // Number of levels GRAPH_OBJ_PROP_LEVELCOLOR, // Level line color GRAPH_OBJ_PROP_LEVELSTYLE, // Level line style GRAPH_OBJ_PROP_LEVELWIDTH, // Level line width GRAPH_OBJ_PROP_ALIGN, // Horizontal text alignment in the Edit object (OBJ_EDIT) GRAPH_OBJ_PROP_FONTSIZE, // Font size GRAPH_OBJ_PROP_RAY_LEFT, // Ray goes to the left GRAPH_OBJ_PROP_RAY_RIGHT, // Ray goes to the right GRAPH_OBJ_PROP_RAY, // Vertical line goes through all windows of a chart GRAPH_OBJ_PROP_ELLIPSE, // Display the full ellipse of the Fibonacci Arc object GRAPH_OBJ_PROP_ARROWCODE, // Arrow code for the "Arrow" object GRAPH_OBJ_PROP_ANCHOR, // Position of the binding point of the graphical object GRAPH_OBJ_PROP_XDISTANCE, // Distance from the base corner along the X axis in pixels GRAPH_OBJ_PROP_YDISTANCE, // Distance from the base corner along the Y axis in pixels GRAPH_OBJ_PROP_DIRECTION, // Gann object trend GRAPH_OBJ_PROP_DEGREE, // Elliott wave marking level GRAPH_OBJ_PROP_DRAWLINES, // Display lines for Elliott wave marking GRAPH_OBJ_PROP_STATE, // Button state (pressed/released) GRAPH_OBJ_PROP_OBJ_CHART_ID, // Chart object ID (OBJ_CHART).

In \MQL5\Include\DoEasy\Data.mqh, add the library new message indices:

The graphical object features the OBJPROP_TIMEFRAMES integer property allowing us to set and receive the object image on any of timeframes. Chart timeframes the object is displayed on can be defined or set by a combination of object visibility flags.
In order to display the description of the visibility flags set for the graphical object, in the file of service functions \MQL5\Include\DoEasy\Services\DELib.mqh, add the function returning the the enabled/disabled flag status for a requested timeframe:
//+------------------------------------------------------------------+ //| 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); } //+------------------------------------------------------------------+
If the value passed to the function features the flags of all timeframes (OBJ_ALL_PERIODS), the object is clearly visible on all timeframes and we immediately return true without checking flags.
If all flags of all timeframes are disabled (OBJ_NO_PERIODS), the object is completely hidden on all timeframes. Return false immediately.
Next, depending on the timeframe value passed to the function, assign an appropriate value to the flag variable the bits of the flags variable are to be compared with. After receiving a bit mask, compare its value with the one obtained when imposing a bit mask on the 'flags' variable and return the result of this bitwise comparison. The function returns true only if the 'flags' variable features the bit checked by the mask.
I have defined the groups of graphical objects. Now let's add this new value to the graphical object properties.
In the file of the base object of all library graphical objects \MQL5\Include\DoEasy\Objects\Graph\GBaseObj.mqh (in its protected section), declare the variable for storing the graphical object group:
//+------------------------------------------------------------------+ //| 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
In the public section of the class, set the method for setting the graphical object group:
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; }
and the method for returning the group:
//--- 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; }
The previously implemented method returning the object visibility flag on the specified timeframe is removed from the public class section:
//--- 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); }
First, it is not optimal. Second, I have already implemented the service function above, which does the same.
Next, declare the method returning the description of the graphical object group:
//--- 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(){;} }; //+------------------------------------------------------------------+
Let's write its implementation outside the class body:
//+------------------------------------------------------------------+ //| 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" ); } //+------------------------------------------------------------------+
Here all is simple. Depending on the value set in m_group and returned by the Group() method, return the appropriate text message.
Let's improve the abstract graphical object class in \MQL5\Include\DoEasy\Objects\Graph\Standart\GStdGraphObj.mqh.
Since some object properties are different for different objects, the implementation of the methods that return these properties should also be different. Such properties should have virtual methods with a common implementation in the abstract graphical object class. For descendant objects, this implementation is redefined in the descendant class.
In the public section of the class, add three virtual methods returning the descriptions of the graphical object type, as well as the price and time of the object first anchor point:
//--- 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
Redefine the methods in the descendant objects for displaying data on a certain graphical object described by the descendant object.
In the protected parametric class constructor, add a new formal parameter — standard graphical object group, while the default constructor immediately receives the group value of -1:

For the method returning the description of the object real property, also replace displaying the anchor point description with calling the method:

For the method returning the description of the object string property, add display of quotes enclosing displayed string properties. To describe a tooltip, display a message that the tooltip is formed by the terminal automatically in case it is not set and is not the "\n" control symbol, which disables the tooltip:

The method returning the description of the object visibility on timeframes:
//+------------------------------------------------------------------+ //| 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; } //+------------------------------------------------------------------+
Here we obtain bit flags of the object visibility on timeframes from the object property.
If none of the flags is set, return the message informing that the object is invisible on every single timeframe.
If, on the contrary, all flags of all timeframes are set, return the message that the object is visible on all timeframes.
If only some of the flags are set, then, in the loop from 1 to 21, we get the timeframe by index using the TimeframeByEnumIndex() service function I implemented long time ago and located in the service function file.
If the object is invisible on a received timeframe, move on to the next iteration to get the next timeframe.
If we can see the object, then we add its short description to the res variable value adding comma and space at the end.
Upon the loop completion, replace the comma at the end of the resulting string with space and remove all spaces and control symbols to the right of the string. The resulting string is returned from the method.
All class improvements are over. Now it is time to create descendant classes of the abstract graphical object class.
Descendant objects of the abstract graphical object
In the current article, I will create the classes of several graphical object groups: Lines, Channels, Gann, Fibo and Elliott.
In \MQL5\Include\DoEasy\Objects\Graph\Standart\, I will create a new file GStdHLineObj.mqh of the StdHLineObj horizontal line class.
The class should be derived from the abstract graphical object, while the parent class file itself should be connected to the created class:
//+------------------------------------------------------------------+ //| 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 { }
In the public section of the class, add the constructor, declare three methods returning the flags of properties supported by the object and the method for displaying object descriptions and properties:
//+------------------------------------------------------------------+ //| "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); } }; //+------------------------------------------------------------------+
The purpose of the methods should be clear from their names. Besides, I have considered similar methods in other classes many times.
In the initialization list of the class constructor, pass the object type — horizontal line to the closed parametric constructor of the parent class, affiliation — does not belong to the program, object group — lines, as well as chart ID and object name values passed to the class 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) {}
The TypeDescription() virtual method returns the description of the graphical object returned by the previously introduced StdGraphObjectTypeDescription() service function, which receives the object type — horizontal line:
virtual string TypeDescription(void) const { return StdGraphObjectTypeDescription(OBJ_HLINE); }
The TimeDescription() virtual method, returning the time description, displays the time set in the horizontal line properties. Since the horizontal line has no time reference, the mouse cursor coordinate is entered into the property when clicking on the chart while placing the object. The appropriate additional message appears in the time description displayed in the journal:
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); }
The methods that return the flags indicating the object support for integer, real and string properties:
//+------------------------------------------------------------------+ //| 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; } //+------------------------------------------------------------------+
The property is passed to each method. Next, if such a property is in the list of supported properties, return true, otherwise — false.
The lists of supported properties will be different for each class since each of graphical objects features its own set of properties. The class constructors are also unique for each of the descendant objects of the abstract graphical object.
The methods displaying the short object name and sending the short object description to the 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) ); } //+------------------------------------------------------------------+
These methods (1) return a string describing the graphical object type and (2) display the graphical object type, as well as its name, assigned ID and object creation time, to the journal.
All other classes describing graphical objects of various types and included in different groups are considered in full below.

These are all the objects of the abstract graphical object descendant classes planned for today. As you can see, they are identical to each other, but differ in types of supported properties. This means that each of these objects will have only the properties inherent in it. The data is not just displayed in the journal. Most importantly, the search and sorting of library objects considers the flags indicating the object supports a certain property. Therefore, when sorting all graphical objects in the collection, for example, by an angle, the final list will not contain objects having no corner since such a property is not supported by them.
I will leave all the above classes for independent analysis.
Now we need to improve the chart object management class located in the file of the graphical object collection class in \MQL5\Include\DoEasy\Collections\GraphElementsCollection.mqh.
Depending on a graphical object added to the chart, a new instance of the standard graphical object class is to be created out of those I have created here. Let's make the necessary improvements in the file.
Include the files of all the classes created here to the file of the graphical object collection class (instead of the previously included GStdGraphObj.mqh) and declare the public method for creating a new object describing the graphical object added to the chart:

In the method, checking the changes in the number of objects on the chart, of the graphical object management class, make improvements in the code block for creating a new object describing a graphical object added to the chart:
//+------------------------------------------------------------------+ //| CChartObjectsControl Check objects on a chart | //+------------------------------------------------------------------+ void CChartObjectsControl::Refresh(void) { //--- Graphical objects on the chart this.m_total_objects=::ObjectsTotal(this.ChartID()); this.m_delta_graph_obj=this.m_total_objects-this.m_last_objects; //--- If the number of objects has changed if(this.m_delta_graph_obj!=0) { //--- Create the string and display it in the journal with the chart ID, its symbol and timeframe string txt=", "+(m_delta_graph_obj>0 ?

I have already created a new abstract graphical object earlier. Now it is time to create an object of an appropriate type using descendant classes developed here. After the object is successfully created, add the affiliation property to it (does not belong to the program). Instead of displaying the short description of the created object, the journal displays the full description of all of its properties.
To select the object that is to be created, use the method creating a new standard graphical object:
//+------------------------------------------------------------------+ //| 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; } } //+------------------------------------------------------------------+
Here all is simple. The method receives the type of the object to be created, ID of the chart the graphical object has been added to and the name of the new graphical object. Next, depending on the type of the graphical object passed to the method, use the new operator to create a new object of the appropriate descendant class of the abstract graphical object and return the result of creating a new object right away.
The method returns either a pointer to a newly created object or NULL in case of any object creation error. As we can see, not all objects are created yet. The remaining ones will be created in the next article along with the improvements introduced into the classes created in the current article. We will need to provide access to all properties of all object anchor points rather than to the very first one.
Everything is ready for testing.
Test
To perform the test, let's use the EA from the previous article and save it in \MQL5\Experts\TestDoEasy\Part84\ as TestDoEasyPart84.mq5.
No changes in the EA are currently required. But for the sake of order, I have saved it in the corresponding article in the terminal folder.
Compile the EA, launch it in the terminal and add some graphical objects to the chart.
Full descriptions of all properties added to object charts are to be displayed in the journal:
What's next?
In the next article, I will continue the development of descendant classes of the abstract graphical object and the collection class of graphical library objects.
All files of the current version of the library are attached below together with the test EA file for MQL5 for you to test and download.
