In the "wmslegend" branch of my fork [1] I've a working wms legend node
that fetches the actual legend image lazily from the Model's data() method
when it is invoked with the role = Qt::DecorationRole.
But for some reason, if I also attempt to load the legend when data() method
is invoked with role = Qt::SizeHintRole, all kind of weird behavior happen,
like crashes or hangs.
Should I expect instances of QgsLayerTreeModel to contemporarly used by
different threads ?
