Detailed Description

The class connects the triggered() signal of a QAction instance with the method of a usual C++ class not derived from QObject.

The class can e.g be used to fill up the context-menu of the view provider classes.

void MyViewProvider::setupContextMenu(QMenu* menu, QObject* receiver, const char* member)
{
    Gui::ActionFunction* func = new Gui::ActionFunction(menu);
 
    QAction* a1 = menu->addAction(QObject::tr("Menu item 1..."));
    func->triggered(a1, boost::bind(&MyViewProvider::doItem1, this));
 
    QAction* a2 = menu->addAction(QObject::tr("Menu item 2..."));
    func->triggered(a2, boost::bind(&MyViewProvider::doItem2, this));
 
    QAction* a3 = menu->addAction(QObject::tr("Menu item 3..."));
    func->triggered(a3, boost::bind(&MyViewProvider::doItem3, this));
}
