[Qgis-user] Change Projection in Projection Properties from a Python PlugIn

[Carson Farmer]

Martin, a quick question regarding this operation:

If I were to setDestinationSrs, and on the fly projection was enabled, 
will this change be reflected on screen? I ask because I would like to 
be able to dynamically 're project' two vector layers on the fly during 
plugin operation, without the user dessesarily 'seeing' that this is 
happening, is this possible?

Cheers,

Carson
