I have a dialog application. OnMouseMove is called anytime the mouse is within the dialog (client area). However, there is no mouse position when my cursor is over a pushbutton. I want something to happen when the cursor is over the pushbutton. The cursor position is present throughout the dialog box but it seems that OnMouseMove is not active while over a control. Any suggestions on how to know if the mouse is over a control? Thank you.
Hi,
the mouse move message is always sent to the window (here dialog / control) the mouse is over, i.e. Your control gets the message and not the dialog. To follow the mouse, i can see two possibilities:
1) You can overwrite OnMouseMove for all of Your controls.
2) You can call SetCapture for Your dialog class. In this case all mouse messages are sent to Your dialog. So You can see, in which control the mouse is. But if You want in this case Your controls to accept clicks etc., You have to sent the messages there Yourself.
Possibly there are better possibilities, but if I don't know them myself...
