Hello,
How to get current size of QWidget placed in QGridLayout? Method width() and height() does not return correct values.

Hi
Just a note.
Do not take width() and height() in the constructor of the widget holding the QGridLayout as resize/layout calculations are
postponed until Widget is shown and might not have correct values yet.

Yeah, it worked! Thanks. Size of the widget is calculated AFTER placing it in the layout.

How should it work otherwise :)
