Another simple Desktop Widget using PySimpleGUI
|
||
|
|
The "Days UNTIL _______" Desktop Widget (Like Rainmeter)
|
||
|
|
|
||
|
|
This widget counts the number of days UNTIL some date of your choosing.
|
||
|
|
Maybe you want to track the number of days until an anniversary?
|
||
|
|
|
||
|
|
Unlike other demos, this one is being released as a .pyw file. If launched on Windows, open with Pythonw.exe so
|
||
|
|
that you don't get a console Window. That's how these desktop widgets are supposed to be launched, with no
|
||
|
|
console. I usually launch them from another Python program that starts them all at once using the Exec APIs
|
||
|
|
built into PySimpleGUI.
