Abstract

GUI forms (module dialogs) are now automatically generated from XML into wxPython. My idea is to create code that is generating the same code into more powerful Qt.

Goal

Create a table of individual widgets, their features and when their are used. Existing GUI in GRASS GIS and also in QGIS GRASS plugin and QGIS Processing plugin are good starting points.

List of standard options in GRASS GIS https://grass.osgeo.org/grass71/manuals/parser_standard_options.html gives list of commonly used parameters which are likely to become specialized widgets (but it is not 1:1 - a lot of them are actually the same map selection widget just with different parameters). The general specification of options and flags is in the programming manual https://grass.osgeo.org/programming7/gislib_cmdline_parsing.html.

There is more ways to do it. We will try to make more files. Nowadays, it is just one file with more than 1000 lines. It is not very readable. We hope that we can change it.
