[Qgis-developer] currentLayerChanged() SIGNAL on right click in interface Legend

[Alexandre Neto]

Hi Larry,

Thanks for the fast answer. You were right, testing in the console I got
the same results as you. Clicking in a white space send the currentLayerChanged
signal also in linux.

So I have double checked my code and... it was my bad, Sorry. I found a bug
in my code, that was not running when currentLayer == None.

Regards,

Alexandre Neto
