Basic Mouse Events
Posted on 2000-04-14
I can't seem to find the WM_DRAG message! There is WM_XBUTTONDOWN, WM_XBUTTONUP, WM_DBLCLICK and WM_MOUSEMOVE, but no message for dragging! Do I have to implement it myself, by catching the DOWN and UP events? Same question about "click" message. Do I have to respond to mouse-up as if it were a click?

why did you think there would be a WM_DRAG message ?
normally on a WM_xBUTTONDOWN you would do a setcapture and set a flag (bDragging=TRUE or something like that)
and then in WM_MOUSEMOVE messages you would do a check for dragging and perfrom your drag operations
then in WM_xBUTTONUP you would do you end drag and releasecapture
