show Tabbar only if there are more than 1 tabs.

[momesana]

Is there an easy way to display the tabbar only when there are more than 1 tabs? Right now, I've a subclassed QTabBar and redefined tabInserted, tabRemoved to check the numbers of tabs and toggle the visibility of the Tabbar accordingly. Is there a more simple way to do this? Maybe a member function of QTabWidget where I can activate/deactivate this behaviour? I could'nt find anything.

#ifndef TABBAR_H
#define TABBAR_H
 
#include <QTabBar>
class TabBar : public QTabBar
{  
    Q_OBJECT
    public:
        TabBar(QWidget *parent=0) : QTabBar(parent){}
    private:
        void toggleVisibility()
        {
            (count() <= 1) ? hide() : show();   
        }
    protected:
        void tabInserted(int) { toggleVisibility(); }
        void tabRemoved(int) { toggleVisibility(); }
};
#endif

#ifndef TABBAR_H
#define TABBAR_H

#include <QTabBar>
class TabBar : public QTabBar
{  
    Q_OBJECT
    public:
        TabBar(QWidget *parent=0) : QTabBar(parent){}
    private:
        void toggleVisibility()
        {
            (count() <= 1) ? hide() : show();   
        }
    protected:
        void tabInserted(int) { toggleVisibility(); }
        void tabRemoved(int) { toggleVisibility(); }
};
#endif

Subclass QTabWidget (not QTabBar) and show() or hide() the tabBar() from within tabInserted() or tabRemoved().

Thanks. Works fine and there is one less class to clutter my code.
