CTkToplevel

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

Example Code:

import customtkinter


class ToplevelWindow(customtkinter.CTkToplevel):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.geometry("400x300")

        self.label = customtkinter.CTkLabel(self, text="ToplevelWindow")
        self.label.pack(padx=20, pady=20)


class App(customtkinter.CTk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.geometry("500x400")

        self.button_1 = customtkinter.CTkButton(self, text="open toplevel", command=self.open_toplevel)
        self.button_1.pack(side="top", padx=20, pady=20)

        self.toplevel_window = None

    def open_toplevel(self):
        if self.toplevel_window is None or not self.toplevel_window.winfo_exists():
            self.toplevel_window = ToplevelWindow(self)  # create window if its None or destroyed
        else:
            self.toplevel_window.focus()  # if window exists focus it


if __name__ == "__main__":
    app = App()
    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().

• .iconify()

  Iconifies the window. Restore it with .deiconify().

• .deiconify()

  Deiconify the window.

• .state()

  Returns the window state: 'normal', 'iconic' or 'withdrawn'
