Hi! I'm trying to do something like the semaphore.py example, but I can't use QThread (can't import QThread from qt, how should I do this?). I don't know if this is the problem but I'm using Thread and after the QApplication.postEvent() (semaphore.py uses QThread.postEvent() ) I've tried calling app.processEvents() (app is a global name for my QApplication). However, the customEvent() isn't called.
Do you know how I could solve this? > On Wednesday 02 July 2003 4:47 pm, Albert Cervera Areny wrote: >> > On Wed, Jul 02, 2003 at 12:07:56PM +0200, Albert Cervera Areny wrote: >> >> >> The problem is that when the event occurs the window isn't >> >> >> >> refreshed >> >> >> >> >> until I move the mouse cursor.
