eventFilter()

bool CustomPlotProxyWidget::eventFilter	(	QObject *	object,
		QEvent *	event
	)

Notifies all graphics items about axes viewport change in QCustomPlot.

Used in RegionOfInterestView to recalculate bounding box and scene positions depending on current state of CustomPlotSceneAdapter.

    // catching zoom/resize events in QCustomPlot
    if (event->type() == QEvent::Resize || event->type() == QEvent::UpdateRequest) {
        scene()->advance(); // notifying all graphics items
        return false;
