Also, note that the Qt event loop will collapse all pending resizes into one
final one.
You should be able to block updating the layouts until the timer expires. Its
been a while but you'll need to subclass the window and don't call the base
class resizes until the timer is done.
I don't think the below will work, but like I said, it's been a whole for me
working with widgets.

Hi John,
I would suggest a short single-shot timer roughly:
resizeEvent
base::resizeEvent
if !mTimer.isRunning
mTimer.start
paintEvent
if !mTimer.isRunning
base::paintEvent
timer slot:
repaint
I'm not sure whether overriding the paintEvent is enough to prevent the child
widgets from painting.
Good luck - please let the group know what you decide with this.
Tony

Subject: [Interest] Finished resizing a window?
We have windows in our application that are potentially expensive to repaint,
so when the user resizes a window we may need to put off repainting until the
resizing is finished. It seems that we don't get mouse down/mouse up events
when the user clicks in the window frame/resize grip area, so I can't wait
until mouse up.
Is that correct?
Is there a solution to this?
Thanks!
