Subject: Remove the flicker issue and the resize issue.

The flicker was caused by removing all widgets (and thus setting
the size of the splitter to zero) and then re-adding them.
I've added four QStackedWdigets that have a consistent size and
the only thing I do now is to set the corresponding widget to visible
without removing / readding anything, and thus, not messing with
the sizes.
