[Qt-interest] Qt mouse grabbing/ungrabbing question

[Zeljko]

Hi,
Qt-4.5.2 (linux, mac, winXP SP2)
Is there any event I can catch under Windows XP that informs me when screen
saver started, display went into sleep, OS went into sleep  ?

I have problem (my customized widget (inherited from QAbstracScrollArea -
text editing) uses mouse grabbing / ungrabbing) under windows xp (mac &
linux works fine), when winxp go into sleep or screen saver activated
(freezes app - mouse grab is still present inside my widget but app doesn't
respond).

tnx
