Keyboard combinations in QTableWidget

[boudie]

Try this:

void MainWindow::keyPressEvent(QKeyEvent *event)
{
	switch (event->key())
	{
		case Qt::Key_Delete:
			qDebug() << "[Del]";
			break;
		case Qt::Key_Up:
			if (event->modifiers() & Qt::AltModifier)
				qDebug() << "[Alt + Up]";
			break;
		case Qt::Key_Down:
			if (event->modifiers() & Qt::AltModifier)
				qDebug() << "[Alt + Down]";
			break;
		default: QMainWindow::keyPressEvent(event);	//	<< important!
	}
 
}

void MainWindow::keyPressEvent(QKeyEvent *event)
{
	switch (event->key())
	{
		case Qt::Key_Delete:
			qDebug() << "[Del]";
			break;
		case Qt::Key_Up:
			if (event->modifiers() & Qt::AltModifier)
				qDebug() << "[Alt + Up]";
			break;
		case Qt::Key_Down:
			if (event->modifiers() & Qt::AltModifier)
				qDebug() << "[Alt + Down]";
			break;
		default: QMainWindow::keyPressEvent(event);	//	<< important!
	}

}

Works here; should work for you also...

This doesn't work for me, infact it never gets called.

I think this is because QTableWidget "intercepts" the Key_Up and Key_Down events before it gets to me since it uses those keys for navigation.
