is it possible to send a message to the gui instance while the Tk
event loop is running?I mean after i create a gui object like

root=Tk()
mygui=SomeUI(root)

and call
root.mainloop()

can i send message to mygui without quitting the ui or closing the
window?i tried some code like
mygui.someMethod()
but it only gets executed after i close the the ui window.Is there a
way to get this message passing while gui is running ?

it's the event loop that keeps Tkinter running, and Tkinter then calls your program (typically via command callbacks or event handlers) when it's time to do something.

so I guess the question here is from where you expect to call that method, and what you expect Tkinter to do when you call it...
