Yeah, I mean when you clicked minimum button on right top of the window.

I'm developing a monitor system with real time chart so the chart should be 
updated no matter the window is visible or just in minimized state. If most 
windowing system optimize this, I think I should draw the chart in memory in 
order to update the whole chart when the window is visible. This might be one 
of solutions.

Hi, there! In my application I need to update UI every 2s. I use QTimer to 
implement this feature. But when the window minimum QTimer stops and 
paintEvent() could not be called. How could I solve this problem? Or could you 
tell me something else to get this feature?


Thank you!
