4. GSASII: GSAS-II GUI

The GSAS-II GUI is normally started using the G2.py file. This will “hack” the PythonPath, if needed, by adding the diectory containing the GSASII directory to the path, allowing GSASII to be run without installing it inside Python. The G2.py invokes the main() routine inside GSASIIGUI.py which actually starts the GUI.

When GSAS-II has been installed inside Python, either of these two commands is sufficient to start the GSAS-II GUI:

python -c "from GSASII.GSASIIGUI import main; main()"

python -m GSASII

For documentation on the main GUI routines see the GSAS-II GUI Components chapter.

4.1. Keyboard Menu Shortcuts

Shortcuts for commonly-used menu commands are created by adding a menu command with a “\tCtrl+” addition such as:

item = parent.Append(wx.ID_ANY,'&Refine\tCtrl+R','Perform a refinement')

This will allow the above menu command to be executed with a “Control-R” keyboard command (on MacOS this will be “Command+R” rather than “Control-R”) as well as using the menu to access that action. The following table lists the keyboard letters/numbers that have GSAS-II assigned actions. are system assigned. Note that there are also plotting keyboard shortcut commands that are implemented in GSASIIplot. These can be discovered from the “K” button on the plot menu bar, as they vary depending on the type of plot that is shown.
