[Qgis-developer] Use the style tab widget in a Python plugin

[Martin Dobias]

Hi Michael

The QgsRendererV2Widget is really just abstract base class meant to be
implemented by custom implementations of renderers.

I think you are looking for this:

from qgis.gui import *
w=QgsRendererV2PropertiesDialog(iface.activeLayer(),
QgsStyleV2.defaultStyle(), True)
w.show()

Cheers
Martin
