You don't have to do that. Use a QStackedWidget instead, add all the 
options "dialogs" (they are pages when it's in stacks) and switch to the 
one that matches your current tab.

If you want to resize the minimum of the stacked widget to the current 
item, you have to explicitly hide the pages that are not currently shown.
