View Full Version : Retrieving mouseover coordinates of QGraphicsScene

23rd October 2006, 15:34
I have a QGraphicsView with a set QGraphicsScene. I'm trying to get the coordinates (on mouseover) of where the mouse is relative to the scene. I'm able to get the coordinates of the entire screen, but not the scene. Is there any way to accomplish this?

This is the code I have so far, but it only returns the window coordinates:

bool Form::eventFilter(QObject *o, QEvent *e)
if (o = ui.graphicsView->viewport()){
QPoint a = QCursor::pos();
QString coord = QString::number(a.x()) + ", " + QString::number(a.y());

You will need QWidget::mapFromGlobal() and QGraphicsView::mapToScene().

Thanks for the tip! this is what I did incase anyone ever needs it:

QPointF a = ui.graphicsView->mapToScene(ui.graphicsView->mapFromGlobal(QCursor::pos()));
