Abstract

The project builds on the work started within the GSoC 2021 project called First steps towards the GRASS GIS Single-Window GUI. Within this coding period, a simple prototype of Single-Window GUI was proposed and partly implemented. It looks good at first glance from screenshots, however, there are many shortcomings and missing features that need to be removed/implemented to provide the Single-Window GUI layout as an optional mode in version 8.2.0.

Goal

The core part of the work will be devoted to the reorganization of the map display status bar. At the moment, the status bar at the bottom of the map display window consists of a text section, a combo box, a mask and a check box. For the Single-Window GUI, the number of widgets must be reduced so that the check box on the right side of the status bar is not shrunk. The solution is to cancel the combo box occupying too much space and implement a new settings dialog accessible from the top map display toolbar. So, the goal of the project is to create the fully functional testable Single-Window GUI mode which addresses the map display window settings through a new dialog.

A nice description of how it could look like is here: ​https://github.com/OSGeo/grass/issues/2017 .

Weekly reports

Week 1

1) What did I complete this week?
This week I worked on the new Map Display settings dialog which is accessible from the Map Display toolbar. I created a separate file for this purpose and proceed to move checkboxes from the Map Display status bar there - Render, AlignExtent, Resolution, and ShowRegion. The Render checkbox is also still accessible through the status bar, however other checkboxes were removed from the status bar combo box and are further available only from Map Display settings, for more info please see ​https://github.com/OSGeo/grass/pull/2031. Furthermore, I and Tomas Zigo managed to fix the closing event for the Map Notebook tab in the Single-Window GUI (see ​https://github.com/OSGeo/grass/pull/2072).

2) What am I going to achieve for next week?
Now it's time to move more complicated items from the status bar combo box. First I am gonna start to work on the Mask which will be newly placed to the main window status bar. It seems like a more complicated task.

3) Is there any blocking issue?
No, it isn't.
