[Solved] QGLWidget Popup menu: QAction not clickable

ilPropheta

Hi,
I've written a simple OpenGL renderer (overriding QGLWidget class) and I've overrided the mouseReleaseEvent function to show a popup menu when I right click. This is the method:

@
void myViewer::mouseReleaseEvent ( QMouseEvent * event )
{
if(event->button() == Qt::RightButton)
{
QMenu *menu = new QMenu("&Menu",this);

    QAction* action_1 = new QAction("&A", this);
    QAction* action_2 = new QAction("&B", this);
    QAction* action_3 = new QAction("&C", this);

    menu->addAction(action_1);
    menu->addAction(action_2);
    menu->addAction(action_3);

    connect(action_1, SIGNAL(triggered()), this, SLOT(slot_action_1()));
    connect(action_2, SIGNAL(triggered()), this, SLOT(slot_action_2()));
    connect(action_3, SIGNAL(triggered()), this, SLOT(slot_action_3()));


    menu->exec&#40;mapToGlobal(event->pos(&#41;&#41;);
    delete menu;
}

}
@

The menu is shown as expected but when I try to click a menu item this seems inactive and the corresponding slot isn't called. What's wrong with this? I thought it was a focus problem but I wrote a similar code for a QTextEdit and it worked fine. I'm using Qt 4.6 on MS Visual Studio 2008 pro.

Thanks!

Marco

Could you please tell us what was wrong? That could help others after you.

Sure but I'm ashamed: I did a trivial error missing Q_OBJECT macro in myViewer header file!

I tried your code snip and it worked just fine, so didn't dig further ...
