I am using customtkinter which is the exact same as tkinter but prettier.
how can I set the master of a tkinter frame class when the class inherits from the frame class in tkinter ??
my problem is because i want frame_right to be the master of wave_prop_inputs frame; which basically means, a frame inside a frame.
I tried using master=frame_right when making an object of the wave_prop_inputs class but that gave me the error init() got an unexpected keyword argument ‘master’
here is my main file:
import customtkinter as ctk
import main
import a_wave_prop.a_view as wave_prop
from constants import TITLE, WIDTH, HEIGHT
#Window Visuals
ctk.set_appearance_mode("System") # Modes: "System" (standard), "Dark", "Light"
ctk.set_default_color_theme("blue") # Themes: "blue" (standard), "green", "dark-blue"
#Main Window
class App(ctk.CTk):
def __init__(self):
super().__init__()
self.title(TITLE)
self.geometry(f"{WIDTH}x{HEIGHT}")
self.protocol("WM_DELETE_WINDOW", self.on_closing) # call .on_closing() when app gets closed
self.grid_columnconfigure(1, weight=1)
self.grid_rowconfigure(0, weight=1)
#Create Two Main Frames
#Left Frame
self.frame_left = main.main_left()
self.frame_left.configure(width=180, corner_radius=0)
self.frame_left.grid_rowconfigure(0, minsize=10) # empty row with minsize as spacing
self.frame_left.grid_rowconfigure(8, weight=1) # empty row as spacing
self.frame_left.grid(row=0, column=0, sticky="nswe")
#Right Frame
self.frame_right = main.main_right()
self.frame_right.rowconfigure((1), weight=1)
self.frame_right.columnconfigure((0, 1, 2, 3, 4, 5, 6, 7), weight=1)
self.frame_right.grid(row=0, column=1, sticky="nswe", padx=10, pady=10)
#Right Frame Children
#wave_prop Inputs Frame
self.wave_prop_inputs = wave_prop.inputs(master=self.frame_right)
self.wave_prop_inputs.grid(row=0, column=0, columnspan=8, rowspan=1, pady=10, padx=10, sticky="nsew")
def on_closing(self, event=0):
self.destroy()
if __name__ == "__main__":
app = App()
app.mainloop()
and here is my 2nd file:

Answer
At this line you try to parse the keyword argument master:
wave_prop.inputs(master=self.frame_right)
To this class that does not expect any sort of arguments:
class inputs(ctk.CTkFrame):
def __init__(self):
super().__init__()
To enable this class to accept an argument with a default value you need to change it like this:
class inputs(ctk.CTkFrame):
def __init__(self, master=None):
Last but not least you need to parse that value to your super class in order to make the super class use it.
super().__init__(master)
You should take a look at a basic tutorial about OOP to benefit by this concept more. In addition I suggest you to use the PEP-8 (Python Style Guide) see naming convention for classes for example. Your class looks like a method for a regular python developer.
