tkinter.place() not working and window still blank

Question

I have a problem with tkinter.place, why it is not working?

class KafeDaun(tk.Frame):
    def __init__(self, master = None):
        super().__init__(master)
        self.master.title("Kafe Daun-Daun Pacilkom v2.0 ")
        self.master.geometry("500x300")
        self.master.configure(bg="grey")
        self.create_widgets()
        self.pack()

    def create_widgets(self):
        self.btn_buat_pesanan = tk.Button(self, text = "Buat Pesanan", width = 20)
        self.btn_buat_pesanan.place(x = 250, y = 100)

        self.btn_meja = tk.Button(self, text = "Selesai Gunakan Meja", width = 20)

I still get this blank Frame even though already use tkinter.place on btn_buat_pesanan

I expect it to have a button on the exact location, like when using tkinter.pack() or tkinter.grid(). Do you have any suggestion ... ... ... ... ..

Try this.

You have to pack the frame like this self.pack(fill="both", expand=True). Because the place did not change the parent size, that's why it didn't visible

import tkinter as tk
class KafeDaun(tk.Frame):
    def __init__(self, master = None):
        super().__init__(master)
        self.master.title("Kafe Daun-Daun Pacilkom v2.0 ")
        self.master.geometry("500x300")
        self.master.configure(bg="grey")
        self.create_widgets()
        self.pack(fill="both", expand=True)

    def create_widgets(self):
        self.btn_buat_pesanan = tk.Button(self, text = "Buat Pesanan", width = 20)
        self.btn_buat_pesanan.place(x = 250, y = 100)

        self.btn_meja = tk.Button(self, text = "Selesai Gunakan Meja", width = 20)
app =tk.Tk()


s = KafeDaun(app)
app.mainloop()

Or you can set the width and height of the frame. super().__init__(master, width=<width>, height=<height>)
