CTkToplevel

CTkToplevel works exactly like the Tkinter.Toplevel, and should be used to create more than one window.

Example Code:

import tkinter
import customtkinter


class ExampleApp(customtkinter.CTk):
    def __init__(self):
        super().__init__()

        self.geometry("500x400")

        self.button = customtkinter.CTkButton(self, text="Create Toplevel", command=self.create_toplevel)
        self.button.pack(side="top", padx=40, pady=40)

    def create_toplevel(self):
        window = customtkinter.CTkToplevel(self)
        window.geometry("400x200")

        # create label on CTkToplevel window
        label = customtkinter.CTkLabel(window, text="CTkToplevel window")
        label.pack(side="top", fill="both", expand=True, padx=40, pady=40)


app = ExampleApp()
app.mainloop()

The example code results in the following windows:

Arguments:

argument	value
fg_color	window background color, tuple: (light_color, dark_color) or single color

Methods:

• .configure(attribute=value, ...)

  All attributes can be configured and updated.

  toplevel.configure(fg_color=new_fg_color)

• .cget(attribute_name)

  Pass attribute name as string and get current value of attribute.

  fg_color = toplevel.cget("fg_color")
  ...

• .title(string)

  Set title of window.

• .geomtry(geometry_string)

  Set geometry and positions of the window like this: "<width>x<height>" or "<width>x<height>+<x_pos>+<y_pos>"

• .minsize(width, height)

  Set minimal window size.

• .maxsize(width, height)

  Set max window size.

• .resizable(width, height)

  Define, if width and/or height should be resizablee with bool values.

• .after(milliseconds, command)

  Execute command after milliseconds without blocking the main loop.

• .withdraw()

  Hide window and icon. Restore it with .deiconify().
