but what i mean i dont understand is sure i can bind a function to a
buttonpress but if i have a def dox(): dododo
and i call it with dox() in the mainscript it will be executed once,
but not again.
so what does the mainloop do, 1srt time it is executed it runs the
mainscript then it it sits and wait s for commands?
