: going through the code again i found that setcapture is already there
: with the first mouse press..and releasecapture on button up..
: but still when the mouse is dragged outside the button region,
: button wndproc gets all the mouse move messages only as long as
: the mouse is inside the button region..
: is ther any way to get the coordinates mouse pos when it is dragged out
: of the button??
No, there isn't. It sounds like there might be a bug in the
SetCapture code. I would put some debug statements in
wingdi.c::SetCapture as well as the button code to make sure that
the capture is in fact being set to your button window.

Greg

: : i tried modifying mwin/winlib/button.c .. tried getting the cursor
: : position outside the region of the button so as to release the mouse once
: : it moves out...but doesnt work out
:
: The problem is that you must capture the mouse with SetCapture
: or your button control won't get any mouse messages when the
: mouse isn't directly within the button window. By capturing the
: mouse at the first mouse press, and then using ReleaseCapture on
: the button up, the button WndProc will get all the messages
: and you can fix the button control implementation bug.
