Relaying a keyPressEvent from one Widget to another

[Live]

You could look into

void QObject::installEventFilter ( QObject * filterObj )

void QObject::installEventFilter ( QObject * filterObj )

To copy to clipboard, switch view to plain text mode 

to apply your filter (y) on your other widget (x)

You would have to reimplement

bool eventFilter(QObject *obj, QEvent *event)

bool eventFilter(QObject *obj, QEvent *event)

To copy to clipboard, switch view to plain text mode 

this method in your widget (y) and call

x->installEventFilter(y);

x->installEventFilter(y);

To copy to clipboard, switch view to plain text mode 

Hope this helps.
