get data from a Toplevel when closing it

[polux]

first, excuse my english...I'm french


I made a class derivated from the Tkinter's Toplevel class like this :

Myclass(Toplevel):

	def __init__(self,master,**arg)
		
			Toplevel.__init__(master,arg)
			self.master = master	


Now, I want to get data from this Toplevel (eg data from entries 
widgets) when I'm closing it.

I've found a trick in the Filedialog.py example file which consists in 
creating a fonction like this :

def go(self):

	self.master.mainloop	
	return data


and an other activated by a 'quit' button for example :

def quit(self):

	data = self.entry.get()		
	self.master.destroy()	
	self.master.quit()


I'm launching my class like this :

root = Tk()
m = Myclass(root)

data = m.go()

root.mainloop()
root.destroy()


It works but they are two problems :

1. It seems to be a 'dirty' method to do this
2. when I'am exiting the root window ( by clicking on a button for 
example), I have to do it twice because there are 2 mainloop() launched



Please help me if there is a better way to do it....I'm sure there is.
