[Qgis-developer] QgsRasterLayer legend interface, where is it gone ?

[Luigi Pirelli]

Hi --strk

I don't think it's useful having the ability to develop new LegendItem
types... before legend refactoring, pupup was introduced because
wasn't possibile to customize legend elements other than having a
little pixmap.
