如何使用 Tkinter 從不同的函數重新分配標簽文本

Question

from tkinter import *




# reassigns variables for label and button texts
def Ctrack(vname, vvalue):
    #global vname
    vname = vvalue
    
    #place holder to check which button has been clicked
    print(vname)
    
    #labeltext = reassign label text bas
    
    
# creates labels and buttons
def buttons():
    root = Tk()
    
    #first label
    
    winlabel = Label(root, text =labeltext )
    winlabel.grid(row = 0, column = 1, padx = 10, pady = 10)
    
    #first button
    but1 = Button(root, text = "button 1", command = lambda *args: Ctrack(0, 1))
    but1.grid(row = 0, column = 2, padx = 10, pady = 10)
    
    #second button
    but2 = Button(root, text = "button 2", command = lambda *args: Ctrack(0, 2))
    but2.grid(row = 0, column = 3, padx = 10, pady = 10)
    
    root.mainloop()

buttons()

如何將按鈕函數中的標簽文本重新分配給我在 Ctrack 函數中分配的變量？

Answer 1

您可以讓 Ctrack() 函數能夠在根窗口上發布標簽。 如果您采用這種方法，您可以在 Ctrack() 中添加“root”作為參數，然后在 Ctrack() 函數中聲明並打包標簽。
