If you need to get access to protected members you need to subclass (C++).
For example you can make properties you need acce3ssible to public for your subclass:
class ExpandableTabWidget : public QTabWidget
{
Q_OBJECT;
Q_PROPERTY( bool expanding_tabs READ isExpanding WRITE setExpanding );
public:
ExpandableTabWidget( QWidget *parent = NULL ) : QTabWidget( parent )
{
}
bool isExpanding() const
{
return tabBar()->expanding();
}
void setTabsExpanding( bool expanding = true )
{
tabBar()->setExpanding( expanding );
}
};
Just before you asked another question, if you subclass QTabWidget
You will need either to make plug-in or "promote" feature, if you want it to be used from designer.
Promotion feature needs less work, but most of the properties has to be set in code (not in the designer ).
