[QGIS-Developer] createAlgorithmDialog in Processing script (within plugin)

[Germán Carrillo]

Hi Matteo,

I've been successfully using *execAlgorithmDialog()* instead [0]:

*processing.execAlgorithmDialog("my_provider:my_algorithm", params)*

where, *params* is a dict with the pre-filled values you have. You can see
an example at [1].

Regards,

Germán
