This does not close the menu, either. Again, on Macintosh (using Cocoa menus).
Though I'm not using the signal from the QWidgetAction in the test case, I
amended the code to try this idea out.
I stashed the SpinBoxAction (derived from QWidgetAction) in the application's
_wAction3 member variable and called trigger() on it in the _onPushButton()
slot:
// Widget Action 3
SpinBoxAction * spinBoxAction = new
SpinBoxAction(QLatin1String("Done"),menu);
app._wAction3= spinBoxAction;
menu->addAction( spinBoxAction );
if( QWidget *widget= spinBoxAction->requestWidget(menu) ) {
if( QPushButton *button = widget->findChild<QPushButton *>() ) {
QObject::connect(button, SIGNAL(clicked(bool)), &app,
SLOT(_onPushButton(bool)));
}
}
...
void SpinApplication::_onPushButton(bool b)
{
Q_UNUSED(b);
if(_wAction3)
_wAction3->trigger(); // doesn't help close the menu, but may have
been necessary to propogate the trigger to receivers of the action.
if(_menu) {
_menu->hide(); // doesn't help
bool closed= _menu->close(); // doesn't work
qDebug() << "Closed:" << closed;
}
}
