[Qt-interest] resizing widgets when user resizes mainwindow

[Ulf-Alexander v. Ceumern-Lindenstjerna]

Hi,

I suggest you take a look at:
http://doc.trolltech.com/4.5/designer-layouts.html

You need to place a layout in all container widgets.

For your problem specifically:
Select the current page of your tabwidget and place a layout in it by
pressing the layout buttons in Designer. Do this for all pages of the
tabwidget. You can test your layout by pressing Ctrl-R and resizing your
window.

QLayout takes care of all resizing so you don't need to implement this
in your code.

Cheers, Ulf
