Signals

pressed(KeyEvent event)
released(KeyEvent event)

Detailed Description

All visual primitives support key handling via the Keys attached property. Key input can be handled via the onPressed and onReleased signal handlers.

These signal handlers have a event parameter, which contains details about the KeyEvent.

Example Usage

The following example shows how the general onPressed handler can be used to test for a certain key:

Item {
    anchors.fill: parent
    Keys.onPressed: {
        if (event.key == Qt.Key_Left) {
            console.log("move left");
        }
    }
}

See Qt::Key for the list of keyboard codes.

Note: Key events are emitted only when you build and run the application for the Qt desktop backend.
