My idea is to collect windowshots and use it later as icons in expose function,
i.e. run xwd as firs action when window looses its focus. To better explaining
I'll attach my source based on existing implementation. It is not clean code,
just early alpha developoment. Please ignore all non-english comments. When I
try to make windowshots now, it has some "bugs", relevant one is described
below:
+ I PipeRead "echo Raise ; xwd <etc.> "
reports error for windows on non-visible page of virtual screen
+ I PipeRead "echo Focus ; echo Raise ; xwd <etc.> "
will make windowshots for all windows, but some windows are not properly
drawn, it needs some time to refreshing them and I do not know how to wait for
it (and I do not like constants like "wait 2 seconds", the better way is when
window reports "OK, I am redrawn just now")
So my idea is to display windowshot from the time when focus is going to
another window - it is good approach (at least for me) to find this window
later on list.
It will eliminate other 2 bugs - flickering of screen done by sequence of Raise
functions and too looooong time to prepare all windowshots for menu.
