Propagating WM_MOUSESCROLL to report control

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Sometimes it is desirable to propagate the mouse wheel input to a child window that does not have focus. The na�ve approach is to fetch WM_MOUSEWHEEL in the parent window and propagate it to the report control. This works until you close the window and get stuck in a never-ending message-loop!
I sense I cannot get the desired behavior with CXTPReportControl. Since WM_MOUSEWHEEL is a bottom-to-top message, it cannot be used for this. I found another message, MSH_MOUSEWHEEL, that goes from top to bottom. Perhaps CXTPReportControl should handle this message?

Anyway, is it possible to accomplish the above? If I scroll inside another child of my parent window, I want to trigger the "mouse wheel" event in the child report control.
