[Tutor] Tkinter - How to get multilple windows

[Alan Gauld]

        def openNew(self):
                app1 = App1(self)
                app1.mainloop()

You don;t need the mainloop here, there is already a
mainloop running, it will send the events to your window
object OK

> #quit class
> class App1(Toplevel):
>         def __init__(self,master=None):
>                 Toplevel.__init__(self,master)
>                 self.grid()
>                 self.createWidgets()
>
>         def createWidgets(self):
>                 textButton =
Button(self,text="Quit",command=self.quit)
>                 textButton.grid()
> app = App()     #instance of the Application
> app.master.title("Sample program")
> app.mainloop()          #wait for the events

> 1. I am getting two windows

Which is what you wanted, yes? I assume the 2nd window only
comes up after pressing the button?

> 2. I want only the object of APP1 to quit not the entire program.

Only run the one mainloop. Otherwise it should be OK.
And you may not want to use self.quit - I think theres
a self.close() for TopLevel... Try a dir(TopLevel)...
