<div>
&gt; I can't seem to find the WM_DRAG <br />
<br />
there isn't one :(<br />
<br />
&gt;&nbsp;Do I have to implement it myself<br />
<br />
yes<br />
<br />
&gt;&nbsp;Do I have to respond to mouse-up as if it were a click<br />
<br />
yes <br />
<br />
why did you think there would be a WM_DRAG message ?<br />
<br />
normally on a WM_xBUTTONDOWN you would do a setcapture and set a flag (bDragging=TRUE or something like that)<br />
<br />
and then in WM_MOUSEMOVE messages you would do a check for dragging and perfrom your drag operations<br />
<br />
then in WM_xBUTTONUP you would do you end drag and releasecapture<br />
<br />

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 &quot;click&quot; message. Do I have to respond to mouse-up as if it were a click?

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
