Automatically resizing widgets when window changes.
OK, I'm not sure how to explain this so here it is: You know when you maximize a main window all the widgets re-size to fix it's parent's space? will I can't figure out how to do it in Qt Designer. I have taken the liberty to attach some pictures showing what I mean.
"Regular window (it's not a virus)":http://puu.sh/22bJw
"other window currently":http://puu.sh/22bLM
as you can see, the blue widget should of resize it self to fit the parent, i.e. the central widget.
