Etienne Good to see that it works :-)
For the record, and in case you are interested in checking it, it might be worth having a look at the "add model from file" action. It is a different approach, just adding the file to the model folder and refreshing the model provider, but just in case it is useful for you. It will also make the model available for the user, outside of your plugin context https://github.com/qgis/QGIS/blob/master/python/plugins/processing/modeler/AddModelFromFileAction.py Regarding the progress indication, once you have your algorithm with parameters set, you can execute it using the AlgorithmExecutor class, which accepts a progress object as parameter. That should let you redirect the output messages and progress indications. Notice that this might change soon, since there is a multithreading implementation of that class being written at the moment. Let me know if you have more questions Cheers 2015-06-23 14:28 GMT+02:00 Etienne Trimaille <etienne.trimai...@gmail.com>: > Hi, > I don't know exactly what happened, but it works now.
