Comment(by sunilkcube):

 Replying to [comment:5 wonder]:

 >Using layers from QgsMapLayerRegistry for zoom full functionality may not
 always work correctly. Not all layers in the registry have to be
 necessarily connected with the map renderer. There could be other
 (unrelated) map canvases with their map renderers with different set of
 layers...

  Thanks for your suggestions ! Can we use the layers directly from the
 QgsMapCanvas(layers got from the QgsLegend) instead of QgsMapLayerRegistry
 for calculating full extent. I have attached a sample patch file regarding
 this, Can you please verify whether this logic is fine ? Waiting for your
 comments ...
