Abstract

This project will mainly focus on extensive Graphical User Interface (GUI) refactoring necessary to prepare GRASS GIS for Single-Window GUI. As the result, I will introduce a very simple Single-Window layout and importantly a good programming base allowing further convenient extension and improvement with additional functions.

Goal

The goal is to create a simple Single-Window GUI (the standard solution in most of the software) which ensures all panels in the form of dockable panes to be visible immediately after startup. Of course, especially long-term users can prefer the existing Multi-Window GUI, so the original option will be retained. For more information, please have a look at a separate page where I present a proposal in detail: ​https://trac.osgeo.org/grass/wiki/wxGUIDevelopment/SingleWindow.

To sum up the schedule: From June 7th to June 20th (2 weeks), I plan to work on the GUI refactoring - separation of main GUI window code, creating a new Workspace Manager as well as a new Layer Manager class. From June 21st to July 11th (3 weeks) I plan to create a new Map Display panel needed for the Single-Window layout and to adapt toolbars in other panels (this would also be the topic for the first evaluation). From July 12th to July 25th (2 weeks) I will work on general factory class allowing me to preserve a Multi-Window layout as well as to create a new Single-Window layout. From July 26th to August 22th (4 weeks) I will work on the integration of all panels (Data, Display, Modules, Console, Python, Map Display notebook) to a basic Single-Window structure.
