[Tkinter-discuss] application busy problem

[Olivier Feys]

Thank you for answering me Michael,

Maybe my question is not well asked :

Is it possible to launch an other thread, for example :

- at the beginning of the application, before all the needed imports, a 
small window appears and displays informations or animations (gif) ?
- the same thing when application is working, this time without hiding 
tha main window, but by inserting a small gif in the corner of the 
application.
