[Qt-interest] Qt Layout Squashing

[Ian Thomson]

Hi,

I vaguely remember reading something in the documentation about this, 
but I'm having trouble finding it now. It was something along the lines 
of when you use QWidget::heightForWidth, it can disable the minimum size 
constraints for the entire layout structure that contains the label. A 
multi-line label uses this function and can cause this effect.

Ian.
