class ContextVariablesPanel(parent, title='Context', initial_variable_idxs=None, initial_subject=None, app=None, sample=None)

A panel that displays and allows to edit variables for a given subject.

The context menu of the panel allows the user to select variables and to make some of them editable. In this case a save changes button will also be displayed. Pressing it will cause the changes to be written into the databases

Parameters:

• parent (QObject) – Qt parent

• app – Optional, an application with the save_screenshot and get_state_dict method. In this case a scenario will be automatically created whenever a variable is first modified.
• sample (list) – list of subjects. This sample will be passed on to the variable select dialog deployed by the panel.
