setDragMode() changes mouse pointer forever

[Cruz]

Hi!

In my QGraphicsView I call setDragMode(QGraphicsView::ScrollHandDrag) in the constructor because my default mouse behavior is to drag scroll the view.
This changes the cursor to the open hand cursor for good, and subsequent calls to setCursor(Qt::ArrowCursor) have no effect. How can I keep the default drag scroll feature and yet set a custom mouse pointer?

You can try overriding viewportEvent in your Qt QGraphicsView and call setCursor() there after the drag mode sets its own cursor. That way your custom cursor will be reapplied each time.

ScrollHandDrag controls the cursor, so setCursor on the view is ignored. Set the cursor on the viewport or subclass the view and force it in events, for example viewport()->setCursor(myOpenHand); then switch in mousePressEvent and mouseReleaseEvent to your closed and open hand cursors while keeping ScrollHandDrag.
