[Павел Ишенин]

Hello, Items specific to the Qt widget set

Den, same request as before: I need access to protected function 
QTabWidget::tabBar().

LCL have ShowTabs property which defiene whether Tab bar or notebook 
(pagecontrol) should be shown. I want to try implement that through

when ShowTabs is false
QWidget_setVisible(QTabWidget_tabBar(), false);

or

when ShowTabs is true
QWidget_setVisible(QTabWidget_tabBar(), true);

Best regards,
Paul Ishenin.
