Greetings.

Is there a code snippet appropriate for cbuilder that shows the best
way to display a image/wireframe/box/whatever when the user is
operating the mouse to select stuff (i.e. between the mouse down and
mouse up)?

I have some c code that does it, but I thought there might be a better
way to to it in cbuilder, given all the events it allows you to
capture. I am dealing with a TPanel on a form.

Thanks
Jeff
p.s. the c code basically does this upon a mouse down message:

set capture
//eat mouse messages until a wm_lbuttonup is encountered
//meanwhile drawing your desired box/rubberband/whatever
for (;;)
{
	if (PeekMesage(msg, 0, WM_MOUSEFIRST, WM_MOUSELAST,
PM_REMOVE))
	{
	    DrawStuff();
	   if (msg.message == WM_LBUTTONUP)
	   {
	      result = true;
	   break;
	   }
	   if (msg.message == WM_RBUTTONUP)
	   {
	      result = false;
	      break;
	   }
	   continue;
	}
	ReleaseCapture();
	return result;// true means something was captured
}
