Re: [Fwd: Send loss of focus notification when changing focus to aWindowsapp?]

Thomas,

	I see.

	I have to say first: I don't know X that well, but I wonder if the
message notification you're talking about would work.

	The WM_MOUSELEAVE message might not be the one to handle this.

	The message to notify a window when it has lost/gained focus is 
WM_ACTIVATE.

	That message really tells you that a window has been
activated/deactivated.

	If I remember well, XWin really only creates ONE window to simulate all
the X Windows.

	Well, it might be presumptuous for me to state the following, but what
the heck:

	When the XWin window receives a WM_ACTIVATE (or WM_ACTIVATEAPP), it
could then notify X that it has either gained focus or lost it.

	'course, I'm not 100% certain this can work, and maybe someone else
here has some brilliant insight why this would/wouldn't work...


Thanks for taking the time to ponder the problem, Thomas.
