Calling paintEvent when I want to

[di_zou]

I have a paintEvent function. However, I don't want this function to be called when the widget is created. I want to control when it is called. I know update() will let me call the paintEvent function, but how do I prevent paintEvent from being called at start up?

[codebehind]

create a bool variable and check it in your paint function
at the creation time set it to false and later when you want the paintevent todraw set it to true.

This famous boolean seems to be already in the widget and can be managed by QWidget::setUpdatesEnabled

Hi
hide the widget after creation.
Normally, paintevent will not be called.
