[Qt-interest] Please help me understand resizing...

[Sven Grunewaldt]

Hi,

thanks for the link! When I change the testcase from QMainWindow to 
QDialog and set the sizeConstraint of the Layout to SetFixedSize, it 
works as expected.

This has two major problems though:
1. It only works with QDialog and NOT with QMainWindow (I guess it has 
something to do with the centralWidget)
2. SetFixedSize enforces a specific size, so the user can't resize the 
window, which is not what I want.

Regards,
Sven Grunewaldt
