Demo - User Setting API to save and load a window's contents
|
||
|
|
|
||
|
|
The PySimpleGUI "User Settings API" is a simple interface to JSON and Config Files.
|
||
|
|
If you're thinking of storying information in a JSON file, consider using the PySimpleGUI
|
||
|
|
User Settings API calls. They make JSON files act like dictionaries. There's no need
|
||
|
|
to load nor save as that's done for you.
|
||
|
|
|
||
|
|
There are 2 interfaces to the User Settings API.
|
||
|
|
1. Function calls - sg.user_settings
|
||
|
|
2. UserSettings Object - Uses a simple class interface
|
||
|
|
|
||
|
|
Note that using the Object/class interface does not require you to write a class. If you're using
|
||
|
|
PySimpleGUI, you are already using many different objects. The Elements & Window are objects.
|
||
|
|
|
||
|
|
In this demo, a UserSetting object is used to save the values from Input elements into a JSON file.
|
||
|
|
You can also re-loda the values from the JSON into your window.
