C++ (Cpp) aboutToScrollTo Examples

Example #1

File: jumptowidget.cpp Project: VengefulVeggie/Miam-Player

bool JumpToWidget::eventFilter(QObject *obj, QEvent *event)
{
	if (event->type() == QEvent::Wheel) {
		return QApplication::sendEvent(_view->viewport(), event);
	} else if (event->type() == QEvent::MouseButtonRelease) {
		QMouseEvent *mouseEvent = static_cast<QMouseEvent*>(event);
		if (mouseEvent) {
			// The A-Z order has been chosen arbitrarily
			int v = mouseEvent->y() * 26 / height();
			// in ASCII, the A letter is 65
			QString s(v + 65);
			emit aboutToScrollTo(s);
		}
		return false;
	} else {
		return QWidget::eventFilter(obj, event);
	}
}

			QString s(v + 65);
			emit aboutToScrollTo(s);
