Disable drawing items on QGraphicsView

Question

I have two QGraphicsView and one QGraphicsScene. One of views don't need to draw qraphicsitems. Is there any way to disable drawing of items on the view?

Answer 1

From the Qt5.2 documentation:

updatesEnabled : bool

This property holds whether updates are enabled.

An updates enabled widget receives paint events and has a system background; a disabled widget does not. This also implies that calling update() and repaint() has no effect if updates are disabled.

You'll probably have to show some code. There are quite a few ways to do this but it's really based on your implementation.

Answer 2

So one of the most simple ways to not draw items - set flag QGraphicsView::IndirectPaint for graphics view and overload drawItems methods in scene and view. Works for me.
