Resizing issue on Qt

Original Reporter info from Mantis: Blaazen @Blaazen

Description:

In attached demo, there is resizing in code.
How to reproduce:

1. Start project and click button -> RadioGroups are NOT resized, it is a bug
   
2. Start project again and click Tab of TabSheet2 -> resizes well

It does not resize, no matter what code is used to display TabSheet2
TabSheet2.Show; or PageControl1.ActivePage:=TabSheet2; or PageControl1.TabIndex:=1;

Also, there is output and the written number obviously does not correspond to real width of RadioGroup1.

With GTK2, it resizes well, no matter if clicked button or tab. Also, resize method run twice with Qt4, with GTK2 only once.
