Hand cursor vs arrow pointer in QGraphicsView
-
After setting "setDragMode(QGraphicsView::ScrollHandDrag)", the cursor is set permanently to a hand while over the graphicsview. I thought that the correct mode was to turn the cursor to a hand only when the left mouse button is pressed. I'd prefer the latter mode of operation, if possible. Is there any way to correct this?

it's clearer for the user to show the possibility to drag by mouse before he starts dragging. That's the reason i guess.
But if you want you can implement the scrolling yourself. Shouldn't be that hard.
Just handle the mouse press/move/release events and use QGraphicsView::scrollContentsBy() and scroll by the delta of the position of last mouse-move event. -
Ah, so it's normal operation. I wasn't sure if I had caused it. I don't remember seeing any other program operate in this fashion, but I understand the reasoning.
I've been considering handling mouse/cursor ops, but I was hoping to put that off til later. As a quick fix, maybe I could set ScrollHandDrag only when the mouse button is down. Not sure if that would work though.
