[Solved] Flickering while widget pops up.

[joonhwan]

I'm creating configuration editor that has quite lots of child widgets and layout. My problem is... how to remove flickering of top-level widget while it pops up with QWidget::show() . If it were due to layouting, I thought it could be solved by calling QWidget::updateGeometry() before calling it but Qt Doc says it does nothing when widget is invisible so it failed.

any idea?

Need your help.

I found why my widget flickered while it pops up.
In deeper level of boxed layout, there was a widget who calls 'show()' in its ctor. after removing it flickering was removed.

Just writing down here to share
