 Uhm. This is really not the common case. Technically, if you want to focus 
another window as a result of user action, KWin::setActiveWindow() should be 
usually the right choice. However, are you sure the visual keyboard should 
really work that way? I cannot really check, because I don't know the source 
(was that [1] meant to mention URL later?). Wouldn't it be for example better 
if the visual keyboard was a non-focusable window, that would simply feed the 
faked keypresses to whichever window is active? Which with XTest would just 
mean generating the events, as you don't need to target those, they'll go to 
the focused window. The user would then normally change active windows as 
usually.

 I don't see any problem with KDE3.1.4 here. CVS HEAD had a bug, but it's 
already fixed.
