Any values changed by the user are change (in-place) by this

Parameters
----------
dictionary : dict
A dictionary defining the input fields (keys) and pre-filled values
(values) for the user dialog
title : str
The title of the dialog window
labels : dict
A dictionary defining labels (values) to be displayed instead of
key strings (keys) defined in `dictionary`. Not all keys in
`dictionary` need to be contained in labels.
fixed : list
A list of keys for which the values shall be displayed in non-editable
fields
order : list
A list of keys defining the display order of keys in `dictionary`.
If not all keys in `dictionary`` are contained in `order`, those
will appear in random order after all ordered keys.
tip : list
A dictionary assigning tooltips to the keys
screen : int
Screen number where the Dialog is displayed. If -1, the Dialog will
be displayed on the primary screen.
sortKeys : bool
A boolean flag indicating that keys are to be sorted alphabetically.
copyDict : bool
If False, modify `dictionary` in-place. If True, a copy of
the dictionary is created, and the altered version (after
user interaction) can be retrieved from
:attr:~`psychopy.gui.DlgFromDict.dictionary`.
labels : dict
A dictionary defining labels (dict values) to be displayed instead of
key strings (dict keys) defined in `dictionary`. Not all keys in
`dictionary´ need to be contained in labels.
show : bool
Whether to immediately display the dialog upon instantiation.
If False, it can be displayed at a later time by calling
its `show()` method.
e.g.:
::
info = {'Observer':'jwp', 'GratingOri':45,
'ExpVersion': 1.1, 'Group': ['Test', 'Control']}
infoDlg = gui.DlgFromDict(dictionary=info,
title='TestExperiment', fixed=['ExpVersion'])
if infoDlg.OK:
print(info)
else:
print('User Cancelled')
In the code above, the contents of *info* will be updated to the values
returned by the dialogue box.
If the user cancels (rather than pressing OK),
then the dictionary remains unchanged. If you want to check whether
the user hit OK, then check whether DlgFromDict.OK equals
True or False
See GUI.py for a usage demo, including order and tip (tooltip).
