[Solved] Why children widgets overlapping in QGridLayout?

magurmach

I have an widget x with fixed size. Then at first I took a QScrollArea and then a QGridLayout which I set as the layout of scrollAreaWidgetContent. Then I started adding some widget x in the layout at (0,0), (0,1), (1,0), (1,1)... of grid layout. Then when I ran the program, strangely when I shrink the window vertically, the widgets overlap.

And as expected, when I increase the window size vertically, they are not overlapped anymore.

But strange thing is this problem does not occurring when I shrink window horizontally. For example,

My question is, why this is happening and more importantly, keeping in mind I want to use gridlayout, how to solve this problem?

Edit: I am using Qt Creator 3.1.1 based on Qt 5.2.1

Hi and welcome to devnet,

You should also add which version of Qt you are using

Did you set the sizePolicy of your widget with QSizePolicy::MinimumExpanding for vertical ?

Nope, but I solved the problem anyway. I don't know why it solved the problem. The scrollbar had a minimum height set. I set it back to 0, recompiled and run, and the problem was gone!
