Properties

◆ key

int KeyEvent::key

This property holds the code of the key that was pressed or released.

See Qt::Key{Qt.Key} for the list of keyboard codes. These codes are independent of the underlying window system. Note that this function does not distinguish between capital and non-capital letters, use the text() function (returning the Unicode text the key generated) for this purpose.

A value of either 0 or Qt::Key_unknown{Qt.Key_Unknown} means that the event is not the result of a known key; for example, it may be the result of a compose sequence, a keyboard macro, or due to key event compression.

◆ keyType

QEvent::Type QWindowSystemInterfacePrivate::KeyEvent::keyType

◆ modifiers

int KeyEvent::modifiers

This property holds the keyboard modifier flags that existed immediately before the event occurred.

It contains a bitwise combination of:

Qt.NoModifier - No modifier key is pressed.
Qt.ShiftModifier - A Shift key on the keyboard is pressed.
Qt.ControlModifier - A Ctrl key on the keyboard is pressed.
Qt.AltModifier - An Alt key on the keyboard is pressed.
Qt.MetaModifier - A Meta key on the keyboard is pressed.
Qt.KeypadModifier - A keypad button is pressed.

For example, to react to a Shift key + Enter key combination:

Item {
    focus: true
    Keys.onPressed: {
        if ((event.key == Qt.Key_Enter) && (event.modifiers & Qt.ShiftModifier))
            doSomething();
    }
}
