Define Default Directory for Qt (Input) Dialog

Sometimes it can be inconvenient to browse paths manually when selecting files or datasets (such as in the scan selector). A solution is to use the TOMWER_DEFAULT_INPUT_DIR environment variable to define the default location for these dialogs.

You can set this environment variable before launching Tomwer from the terminal:

export TOMWER_DEFAULT_INPUT_DIR={location}

Alternatively, you can set it within a ‘Python’ widget in Tomwer:

import os
os.environ["TOMWER_DEFAULT_INPUT_DIR"] = "my/new/default/path"

Warning

Do not forget to execute (run) the script to activate the new environment variable.
