QWidget paintEvent update in time

[ugiwgh]

I draw a qpixmap in paintEvent of QWidget. When I resize QWidget, the qpixmap will be changed.
On linux, it is changed in time. But on windows, it is changed when I release mouse.
I want to change it in time on windows. I don't know how to reslove this.
Any help will be appreciated.

How do you trigger the repainting?
Do you call update()? If yes, have you tried calling repaint()?

I send a signal in resizeEvent, and then paintEvent will be called. And QPainter::drawPixmap() is be executed. I've tried to add update() or repaint() in resizeEvent(), but it no use.

Are you using threads in your application? resizeEvent() will be called in the application thread so there is no need for Qt:irectConnection unless the object you are trying to call the slot on lives in a different thread. In which case you should simply move your slot to another class.
