GTK2: Set TPanel visible to false on nonvisual TabSheet doesn't work

Original Reporter info from Mantis: Michl @michl1
  • Reporter name: Michl

Description:

Setting a TPanel visible to false on nonvisual TabSheet doesn't work. Same for TGroupBox (maybe more). TButton works fine.

Windows 7 (win32) or the Linux with target Qt works fine.

The bug occur, if you set TPanel.visible := false in events TForm.OnShow or TForm.OnActivate. The bug doesn't occur, if you do it in TForm.OnCreate.
