I have managed to work the QGIS Web Client on my server with the basic buttons and functions.
Now I would like to add "extra" geoprocessing tasks (for example create buffer), based on WPS.
I understand how to add new button to the QGIS Web Client toolbar by the Customizations.js file, but I can not find any working example about how to define the button's function as a geoprocessing task, based on a public WPS (for example Zoo project's WPS capabilities, which I can use in QGIS Desktop).
Is it possible to do? If yes, could you please help me with the basics or show me a working example and code behind it?
