Demo of a Better File / Folder Input Window
|
|
|
|
This construct is very common in PySimpleGUI.
|
|
[sg.InputText(size=(50,1), key='-FILENAME-'), sg.FileBrowse()],
|
|
|
|
The new user settings APIs can significantly improve the experience. Now instead of being
|
|
shown a blank input element, the user is shown their previous entry and a history of their
|
|
prior entries to choose from.
|
|
|
|
Two new capabilities are presented in this demo
|
|
1. Recalling the last entry
|
|
2. Recalling a history of all of the previous entries as a Combo instead of Input Element
|
|
|
|
The previous operations you're used to remain. You can paste a filename/full path into the combo.
|
|
You can also use the browse button as before.
|
|
|
|
But, you also get the 2 history features - last entry used, list of previous choices.
|
|
|
|
If your window is not a 1-shot, add an event loop instead of a read with close paramter
