QGraphicsView - how to disable mouse and keyboard scrolling

[kid2000]

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)

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 );

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

mouse wheel events still go thru tho

use eventFilter() and filter the mouse events ...

bool myGraphicsView:: eventFilter(QObject *ob, QEvent *e)
{
        if(ob == item_need_filter && e->type() == QEvent::MousePress /**any event u want to filter**/) {
                .......
                }
                return true;
        }
         return QWidget::eventFilter(ob, e);
}

bool myGraphicsView:: eventFilter(QObject *ob, QEvent *e)
{
        if(ob == item_need_filter && e->type() == QEvent::MousePress /**any event u want to filter**/) {
                .......
                }
                return true;
        }
         return QWidget::eventFilter(ob, e);
}
