== 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 3000 lines. It is not very readable. We hope that we can change it. 

== Notes ==

In the first version, creating GUI will work just as script started from GRASS. Of course I want to implement it as normal function (there is variable "gui" in GRASS), but it's not necessary. When the GUI is ready and compatible with many functions, then tere is possibility to make it. (not in timeline, additional goal)

The same is with styling. I will try to make everything very similar to current GUI, but I didn't make any window in timeline for that. I will work on that within all the GSoC period assuming that I have the time. 

I have a problem with the end of the june. I have Final Examinations at my school so maybe I won't have so much time. I will try to make everything here ahead of time. In the case I won't, I will definitely catch up it after this period. It will be same for every hiatus that can raise.

 == Requirements ==

 [http://grass.osgeo.org/download/software/#g71x  GRASS 7.1]

== Development ==
 === Weekly reports ===
  ==== May 23 - 27 ====

Designed basic GUI shuck. From XML is now automatically generated GUI with name, keywords and basic layouts. 

Code now wors as a script with parameter - for example r.buffer
