[Qgis-developer] Add Layer to overview

[Germán Carrillo]

Well, the 'actionAddToOverview' method from QgisInterface do work, just add
this line to your code:

      self.iface.actionAddToOverview().activate( 0 ) # '0' is the signal to
emit, in this case "QAction.triggered()"

And this way you activate the AddToOverview action from QGis. It adds the
active layer to overview map. So, you don't need the workaround.

Regards.
