QAction Qt::Key_Return shortcut is triggered by user entering values in GUI

JulienMaille

Dear all,
I have an issue with associating a shotcut to a QAction. After mapping Enter to an action like this: @myAction->setShortcut(Qt::Key_Return);@ This action is triggered when I type a value in a QSpinBox and then press enter. I was expecting the spinbox to "accept" the event, so it's not caught by the mainwindow.
I've seen that I can add a context to my shortcut, I tried all values but this does not solve my issue.

Thanks a lot for your help.

Hi. Try next in you MainWindow:

@
QAction* action1 = new QAction(this);
action1->setShortcut(QKeySequence(tr("Alt+F"))); // Or whatever you need
addAction(action1);
connect(action1, SIGNAL(triggered()), this, SLOT(action1Triggered()));

I don't understand why your code would solve my issue? This is more or less what I'm already doing.
Could you explain it? Thanks a lot

ok.

To process key-strokes in QLineeEdit you should override virtual function
@
virtual void keyReleaseEvent(QKeyEvent *event)
// or
virtual void keyPressedEvent(QKeyEvent *event)
@

my example adds global shortcut to main window
you can try to install an event filter to QLineEdit - call
@
you_QLineEditObjPtr->installEventFilter(aMainWindowObjPtr);

I would like to avoid subclassing all the standard widgets that do not accept and consume the Enter pressed event.
