activateWindow, forceActiveWindow

[Kevin Kofler]

Hi,

I believe the current implementations of activateWindow and forceActiveWindow 
in kwindowsystem_win.cpp don't implement the same semantics as their X11 
versions. The issue is that SetActiveWindow only works within a thread (in 
particular, only in the same application), whereas on X11, 
KWindowSystem::activateWindow works just fine across applications. Moreover, 
forceActiveWindow doesn't really force the active window, i.e. bypass focus 
steal prevention, as it's supposed to.

I believe it would be more compliant to have activateWindow call 
SetForegroundWindow( win ); (is calling SetActiveWindow first really 
necessary?) and forceActiveWindow use some hack like 
http://vb.mvps.org/articles/ap199902.pdf (I've also seen some other hacks, 
like sending a fake user input event to the window to activate, but I can't 
find them now.)

I can't test this though (only running GNU/Linux these days).
