Does setting the QTimer interval to 0 help anyhow? I've been struggling with creating an idle event for a rendering loop and everytime I got a different problem. 4.8 fixed one problem I had before but now I'm facing another. Whenever I add my graphics window custom control to the form, the timer is no more triggered until I either resize or move the window. Should I go back to MFC and leave open-source buggy libraries? Come on, gimme a break!!!
