Adding widgets to a QGraphicsView's margins

[nmather]

Hi,

With a QGraphicsView I can set the margins of the viewport with setViewportMargins (inherited from QAbstractScrollArea), but I am then unsure how to actually place widgets in those margins.

I tried both:


viewport()->layout()->addWidget( myWidget );

and


layout()->addWidget( myWidget );

But each case results in a seg fault, which I think means the layout in both cases hasn't yet been instantiated. However I would have thought the QGraphicsView must have a layout already, in which the viewport is placed, and the viewport must have a layout for which the margins get set?

Any tips on how to add widgets into the margins is greatly appreciated :)

You must not use the layout. You just position the widgets in the available left ant top areas.
To position the widgets you can use move().

Thanks Marcel! I got it to work now. My problem was, for the widgets I was trying to put in the margins I wasn't properly passing the GraphicsView to them to be their parent -- the parent was just being set to 0, so of course nothing showed up!
