Is it possible to override in c++ application mouse events?
or even get selected layer, shape id, etc.?
MapEvents.MouseDownEvent += …
How does it in the c++ app?
Do I have to catch MousEvents by myself in the c++ app?
Hello @Mariusz, and welcome.
Note that you will have to set the SendMouseDown, SendMouseMove, and SendMouseUp properties = True for the OCX to generate mouse events.
Beyond that, what framework are you using in c++? Are you using MFC? Whatever framework you are using to load the OCX should expose the Map events for you to hook them.
Hope that helps.
Thank you for your answer
Yes, I’m using MFC.
And I see now the CDMap class has not any Send… function.
So it can be created without these functions?
In VS 2017 I have a “Cannot find coclass for interface _DMapEvents” error
But in VS 2019 it is created and looks like DMap class
BOOL CDMapEvents::Create(…), CDMapEvents::MouseMove(…) etc.
The map is created by:
mapWinGis.Create(NULL, WS_VISIBLE, mapRect, this, IDC_MAP);
When I try to create CDMapEvents same way its fails.
