[Qt-interest] layers of QGraphicsView

[Malyushytsky, Alex]

In general layer ( a group of any items ) probably might be presented as a QGraphicsItemGroup,
but it may have nothing to do with QGraphicScene. It is basically a list of items groups.

You may subclass all items you need to keep the pointer to the "layer" they belongs to.

Hi All
     Please see the pic bellow.
I want to design a software like the picture show:
many layers in the left side:
I want to use QGraphicsScene to control and manage the QGraphicsItems in layer.
And QGraphicsView is the interface of graphic editor.
But, I don’t know how to display muliti layers. Because, “setScene” of QGraphicsView could only set one scene.
Or I need to use QGraphicsItemGroup to design the layers?
Anybody has this experience?
Thanks
Ken
