[Qgis-user] Help reusing QGIS action

Tue Jun 2 22:38:24 PDT 2015

hi Brent,

the action is saved in the qml, too (not independently from style, though)

elaborating the Python-plugin thought you can create an action for the 
active layer like that:
layer = self.iface.activeLayer()
layer.actions().addAction(1, #actionType 1 = Python action
     "show species", <Python code>)

if you put that into a slot connected to a menu or button you are set. 
Users can create this action for any of their layers (won't make sense 
for all of them, I am sure but that's the user's responibility)

It would be great to be able to do the same thing with actions - create a library of actions for institutional WFS services that users can re-use - which is where your suggestion of Python is a good one - being platform independent.
