asyncUpdate

void DLS::Graph::asyncUpdate ( )

signal

QWidget::update() does not trigger a repaint event, if the widget is not visible.

If this widget is used with qml it's render() function is used for painting thus no repaint trigger. The parent which captures events from Graph with an eventFilter does not get informed about the update. So we need this signal here.
