Qt4 layout problem, QWidget children shrinks on resize
Message 1 in thread
Hi,
I'm porting to Qt4 and get some exhausting problems.
I've a QWidget whit some child widgets (QLabel, QLineEdit, ...) in a
QVBoxLayout.
If I scale down this widget at runtime the children shrinks to a very small
height. But why, I think child widgets should take automatically as much
space (in height) as they need! I've set back all minSizes to default so
that this should not be a problem.
Did anyone have the same problem?
Thanks for help/advise,
Adrian

Yes, but a label or line-edit might need very little minimum space. With
the resize you force them to be as little as they can be.

Well minimumSize normally is 0, so unless the minimumSizeHint function
gives other information each widget can be resized to 0 size.
If you need to preserve a specific minimum size use the minimumExpanding
size policy and set a reasonable minimum size.
