如何重新定位按鈕？

Question

如何修復我的程序的這一部分以將按鈕重新定位到屏幕上的新位置？

movingbutton1 = Button(root, text = 'Click Me' ...).place(relx = .5, rely = .5) 
time.sleep(3) 
movingbutton1(root, text = 'Click Me' ...).place(relx = .3, rely = .3) 

Answer 1

要移動放置的小部件，您可以使用place_configure(relx=new_x, rely=new_y)。

要在用戶單擊按鈕時移動按鈕，請傳遞將此按鈕移動到按鈕的command選項的功能。

import tkinter as tk 
import random 

def move(): 
    x = random.random() 
    y = random.random() 
    moving_button.place_configure(relx=x, rely=y) 

root = tk.Tk() 

moving_button = tk.Button(root, text='Click Me', command=move) 

moving_button.place(relx=0.5, rely=0.5, anchor='center') 

root.mainloop() 

Answer 2

可以使用.after方法一定的時間後，移動你的控件，如圖所示：

import tkinter as tk 
import time 

class App(tk.Frame): 
    def __init__(self, parent, *args, **kwargs): 
     tk.Frame.__init__(self, parent, *args, **kwargs) 
     self.button1 = tk.Button(parent, text = 'Click Me') 
     self.button1.place(relx = .5, rely = .5) 
     self.button1.after(3000, self._moveButton) # Call method after 3 secs 

    def _moveButton(self): 
     # reposition button 
     self.button1 .place(relx = .3, rely = .3) 

if __name__ == "__main__": 
    window = tk.Tk() 
    window.geometry('500x200') 
    app = App(window) 
    window.mainloop() 

Answer 3

下面的答案是，你要

movingbutton1 = Button(root, text = 'Click Me' ...) 
movingbutton1.place(relx = .5, rely = .5) 
time.sleep(3) 
movingbutton1.place(relx = .3, rely = .3)
