GRASS GIS - wxPython Graphical User Interface (wxGUI)
February 19, 2025 ยท View on GitHub
1 - REQUIREMENTS
GRASS GIS >= 6.4 Python >= 2.4 Python ElementTree (only for Python 2.4) wxPython >= 2.8.10.1 NumPy >= 1.0.4 PIL >= 1.1.7
2 - STARTUP WITH GRASS INITIALIZATION
If you want to launch wxPython GUI automatically, start GRASS with
--gui parameter
$ grass --gui
3 - STARTUP FROM GRASS TERMINAL
Simply run
$ g.gui wxpython
from the GRASS terminal.
You can also specify workspace file to load on startup.
$ g.gui gui=wxpython workspace=myworkspace.gxw
4 - DEBUGGING
To enable GUI debug messages on given level set WX_DEBUG environment variable, e.g.
$ g.gisenv set="WX_DEBUG=3"
5 - CLI BASED DISPLAY USAGE
Use command d.mon (shell script in gui/scripts directory) to start map display:
GRASS> d.mon wx[0-6]
After a while, new window should appear. If this is your case, add some raster layer to the map display:
GRASS> d.rast aspect
And try the vector layer too
GRASS> d.vect roads
You should be able to zoom && pan through the map, once the layers are displayed. You should be also able to store the display content as well as clear the display and start from scratch.
6 TRANSLATION HANDLING
Notes:
- Help part of menu entries is coming from the module descriptions
- The menu is maintained manually in xml/menudata.xml
Update of module description strings in xml/menudata.xml:
- in a GRASS session, run tools/update_menudata.py
From this (updated) xml/menudata.xml, the gettext strings are generated via Makefile and stored into the file "menustrings.py".
When generating the po files in locale/po/ but locale/Makefile, all .py files are parsed and the strings are stored in locale/po/grasswxpy_XX.po
