Notification Window Demo Program
|
||
|
|
Shamelessly stolen from PySimpleGUI user ncotrb
|
||
|
|
|
||
|
|
Displays a small informational window with an Icon and a message in the lower right corner of the display
|
||
|
|
Option to fade in/out or immediatealy display.
|
||
|
|
|
||
|
|
You can click on the notification window to speed things along. The idea is that if you click while fading in, you should immediately see the info. If
|
||
|
|
you click while info is displaying or while fading out, the window closes immediately.
|
||
|
|
|
||
|
|
Note - In order to import and use these calls, you must make the call from a "main program".
