我想創建多個窗口使用tkinter,但我目前沒有成功......當我創建一個子窗口並在其上放置一個按鈕時,該按鈕創建在父窗口!Tkinter - 在錯誤的屏幕上創建按鈕
from tkinter import *
class Login_screen(Frame):
def __init__(self,master):
Frame.__init__(self, master)
self.grid()
self.button1 = Button(text = "Open",command = lambda: self.open_login())
self.button1.grid()
def open_login(self):
self.root2 = Toplevel()
self.root2.geometry("400x200")
self.app2 = Main_screen(self.root2)
class Main_screen(Frame):
def __init__(self,master):
Frame.__init__(self,master)
self.grid()
self.button = Button(text = "Close",command = lambda: self.close_windows())
self.button.grid()
def close_windows(self):
self.grid_forget()
root = Tk()
root.geometry("800x600")
app = Login_screen(root)
root.mainloop()
