I am trying this code abive and but I have issues.
1. Button is not appearing unless I put ofset 0.
2. And it behaves the same, after click it remains pressed unless click again. I need the button after release the mouse became to released.
And additional question
Is it possible to put the event handler to the same function BitmapLabelCreate, for example OrderSend.
@Marco vd Heijden thank you for fast reponse :)

If you want to push it back you can do so in the OnChartEvent() just reset the button state when it is clicked.
Note that OnChartEvent() does not work in the tester so you need a work around for that if you want to use it in the tester.
//+------------------------------------------------------------------+ //| ChartEvent function | //+------------------------------------------------------------------+ void OnChartEvent(const int id, // Event identifier const long& lparam, // Event parameter of long type const double& dparam, // Event parameter of double type const string& sparam) // Event parameter of string type { //--- the left mouse button has been pressed on the chart if(id==CHARTEVENT_CLICK) { Print("The coordinates of the mouse click on the chart are: x = ",lparam," y = ",dparam); } //--- the mouse has been clicked on the graphic object if(id==CHARTEVENT_OBJECT_CLICK) { Print("The mouse has been clicked on the object with name '"+sparam+"'"); //--- Here you can push back the button state... //+------------------------------------------------------------------+ // chart event reset button state //+------------------------------------------------------------------+ ObjectSetInteger(0,sparam,OBJPROP_STATE,0); ChartRedraw(); //+------------------------------------------------------------------+ } //--- the key has been pressed if(id==CHARTEVENT_KEYDOWN) { Print("The key with code ",int(lparam)," has been pressed"); } //--- the object has been deleted if(id==CHARTEVENT_OBJECT_DELETE) { Print("The object with name ",sparam," has been deleted"); } //--- the object has been created if(id==CHARTEVENT_OBJECT_CREATE) { Print("The object with name ",sparam," has been created"); } //--- the object has been moved or its anchor point coordinates has been changed if(id==CHARTEVENT_OBJECT_DRAG) { Print("The anchor point coordinates of the object with name ",sparam," has been changed"); } //--- the text in the Edit of object has been changed if(id==CHARTEVENT_OBJECT_ENDEDIT) { Print("The text in the Edit field of the object with name ",sparam," has been changed"); } } //+------------------------------------------------------------------+
ObjectSetInteger(0,sparam,OBJPROP_STATE,0); Sleep(100); ChartRedraw();
In this case button behave like it should
Note that OnChartEvent() does not work in the tester so you need a work around for that if you want to use it in the tester.
What should I do to make the button work in tester, can you please explain.
Also, why the button doeasnt appear unless I set offset to 0.
In this case button behave like it should
Not really like it should, but how you like it to behave.
You can also detect the button press by reading it's state;
bool pressed = ObjectGetInteger(0,"button",OBJPROP_STATE);
This will work in the tester, in the OnTick(), whereas the OnChartEvent() will not so keep that in mind when you want to use the button in the strategy tester.

Can you please show sample of code how make the button alive in tester
OnTick() { if(ObjectGetInteger(0,"button-name",OBJPROP_STATE)) { Print("Button pressed !"); ObjectSetInteger(0,"button-name,OBJPROP_STATE,0); ChartRedraw(); } }
Good, thank you. The button now works on strategy tester and runs the function.
But it doesnt change the appearance to pressed/released.
Also, if I put the same function for button click into OnTick and OnChartEvent, they will not cause conflict?

Yes they will conflict.
So you use a switch to see if it's being tested or not.
MqlInfoInteger(MQL_TESTER) If you want the image to toggle between pressed and not pressed then don't reset the button state, or simply swap the images it will need a bit more coding in that case.

Hi guys
I am making panel, which as background image inserted as OBJ_BITMAP_LABEL, I need to place a button which have two bitmap files (pressed / released). Need advise how to make OBJ_BITMAP_LABEL to behave like button (press and release on mouse click).
I have tried to use CBMPButton class, it places the button, but doeasnt work as classic button, rather it is pressed on click and remains pressed unless click again. Here is the code sample.
