[Qt-interest] Layout issue

[Sajjad]

Hello Alex,

I am getting the same scenario even after i detached the layout as suggested
in the previous attachment you sent.

I have the main layout as vbox layout.

The label and the line edit in the horizontal layout.


The checkboxes in the grid layout that are added dynamically with the
keypress.

Any other point of view on that?


Regards
Sajjad
