You can call the 'size' function from any widget. If you call this from the main window it will return the size of the main window.
QSIze size = this->size();
In some cases the size may not be correct (in the constructor before the widget is completely created or displayed) until after the widget is first shown. Deferring this to the first call of resizeEvent() is a good idea.
If you assign a layout to the window, and put the tab in it, Qt can then
automatically adjust the size if user resize the window.
It takes a little bit to learn layouts but the reward is great.
