Way to do radio buttons in Qt 4.4.3 menus

Use the QtActionGroup to menu items and look like an radio button as:

QActionGroup* group = new QActionGroup( this );
 
ui->actionTest1->setCheckable(true);
ui->actionTest2->setCheckable(true);
ui->actionTest3->setCheckable(true);
 
ui->actionTest1->setActionGroup(group);
ui->actionTest2->setActionGroup(group);
ui->actionTest3->setActionGroup(group);
