How to close "Tk" Window without closing whole GUI

[Daniel M]

Hi, I am writing a program, in which everything interesting happens in a Toplevel window that I have made. However, whenever I run the program, I get both the standard Tk window and the Toplevel window that I made. How do I get rid of the first Tk window, without closing out of the program completely?

Thanks

        self.top = top
            
        self.L0 = Label(top, text = "Initial Data:").grid(row=0,column=0, sticky=E)

        self.L3 = Label(top, text = "Current State:").grid(row=3,column=0, sticky=E)

        self.Name0 = Entry(top, state = "readonly", width=40).grid(row=0,column=1, sticky=W,columnspan=3)

root = Tk()

app = App(root)

root.mainloop()

master.withdraw () hides a top level window.

This will hide the root window and return to it if the user chooses to close the TopLevel window:

class App:
    def __init__(self, master=None):
        self.master = master
        master.state("withdraw")
        top = Toplevel()
        top.protocol("WM_DELETE_WINDOW", self.exit)
        top.title("Adjust Ellipse")
        self.top = top

Method exit:

    def exit(self):
        self.master.deiconify()
        self.top.destroy()

Big thanks bvdet. This is the part that I ended up using:

top = Toplevel()
top.title("Adjust Ellipse")
top.protocol("WM_DELETE_WINDOW", self.exit)

self.master = master
master.withdraw()

Along with the method:

def exit(self):
    self.master.deiconify()
    self.master.destroy() #Exit all when 'top' is closed

This does exactly what I wanted. Thanks again.

You're welcome. I learned a couple of things myself.

The simple solution is to use "master" instead of creating a new Toplevel. Then you don't have to go through the additional gyrations to close the master GUI.

from Tkinter import *
import tkFileDialog as tkf
 
filenames = {}
 
class App:
     def __init__(self, top):
 
#         top = Toplevel()
         top.title("Adjust Ellipse")
 
         self.top = top
 
         self.L0 = Label(top, text = "Initial Data:").grid(row=0,column=0, sticky=E)
         self.L1 = Label(top, text = "After Change #1:").grid(row=1,column=0, sticky=E)
         self.L2 = Label(top, text = "After Change #2:").grid(row=2,column=0, sticky=E)
         self.L3 = Label(top, text = "Current State:").grid(row=3,column=0, sticky=E)
 
         self.Name0 = Entry(top, state = "readonly", width=40).grid(row=0,column=1, sticky=W,columnspan=3)
         self.Name1 = Entry(top, state = "readonly", width=40).grid(row=1,column=1, sticky=W,columnspan=3)
         self.Name2 = Entry(top, state = "readonly", width=40).grid(row=2,column=1, sticky=W,columnspan=3)
         self.Name3 = Entry(top, state = "readonly", width=40).grid(row=3,column=1, sticky=W,columnspan=3)
 
         self.Butt0 = Button(top, text = "Select", command=self.openfile0).grid(row=0,column=4)
         self.Butt1 = Button(top, text = "Select", command=self.openfile1).grid(row=1,column=4)
         self.Butt2 = Button(top, text = "Select", command=self.openfile2).grid(row=2,column=4)
         self.Butt3 = Button(top, text = "Select", command=self.openfile3).grid(row=3,column=4)
 
     def openfile0(self):
         tkf.askopenfile()
 
     def openfile1(self):
         tkf.askopenfile()
 
     def openfile2(self):
         tkf.askopenfile()
 
     def openfile3(self):
         tkf.askopenfile()
 
root = Tk()
 
app = App(root)
