QGraphicsView - how to disable mouse and keyboard scrolling

In my application I have QGraphicsScene with pixmap added and all is viewed in QGraphicsView with scrollbars off. The program window is smaller then pixmap and when I press arrow keys or move mouse wheel the pixmap is being moved.

How do I disable that so even if the pixmap is bigger than window it won't be moved by keyboard or mouse unless I use my events for that?

(I tried to set interactive property to false but that didn't work)

Solution

  • I believe the easiest solution would be to set FocusPolicy of QGraphicsView to NoFocus and then process all key events in main window.

    ui->graphicsView->setFocusPolicy( Qt::NoFocus );
