[Qgis-developer] pyqgis load a memorylayer in plugin but not show it in layerlist/legend

[Matthias Kuhn]

The API seems to make that not too hard ;)

http://qgis.org/api/classQgsMapLayerRegistry.html#a3d0d19c86467341bdd62471c5de61376

QgsMapLayer <http://qgis.org/api/classQgsMapLayer.html> *
QgsMapLayerRegistry::addMapLayer 	( 	QgsMapLayer
<http://qgis.org/api/classQgsMapLayer.html> *  	/theMapLayer/,

	
	bool  	/addToLegend/ = |true|,

	
	bool  	/takeOwnership/ = |true| 

	)
