线程和 Tkinter/Python3

问题
我需要帮助连接 Tkinter 的附加流。我需要不断更新Label中的光标坐标，但我就是想不通（+如果可能的话，你能告诉我如何构造一个像这样的变量：“text”，这里是Label（text= “坐标：”，字体=“Arial 12”）。

1. import win32api
   
2. from threading import Thread
   
3. from tkinter import *
   
4. root = Tk()
   
5. #Подключение модулей}
   
6. 
   
7. #Переменные{
   
8. xcoord = "null"
   
9. ycoord = "null"
   
10. h_x = 0
    
11. h_y = 0
    
12. #Переменные}
    
13. root.title("Utility")
    
14. root.geometry("400x500+100+100")
    
15. root.columnconfigure(0, weight=1)
    
16. root.resizable(False, False)
    
17. #root.iconbitmap('') Иконка
    
18. root["bg"] = "grey30"
    
19. def coordinates():
    
20.     while True:
    
21.         h_x, h_y = win32api.GetCursorPos()
    
22.         print(h_x, h_y)
    
23. 
    
24. #Лейбл показа координат{
    
25. select_mode = Label(text="Координаты:", font="Arial 12")
    
26. select_mode['bg'] = "grey30"
    
27. select_mode['fg'] = "white"
    
28. select_mode.place(x="10", y="470")
    
29. 
    
30. select_mode = Label(text='x = ', font="Arial 12")
    
31. select_mode['bg'] = "grey30"
    
32. select_mode['fg'] = "white"
    
33. select_mode.place(x="120", y="470")
    
34. 
    
35. select_mode = Label(text=h_x, font="Arial 12")
    
36. select_mode['bg'] = "grey30"
    
37. select_mode['fg'] = "white"
    
38. select_mode.place(x="140", y="470")
    
39. 
    
40. select_mode = Label(text='y = ', font="Arial 12")
    
41. select_mode['bg'] = "grey30"
    
42. select_mode['fg'] = "white"
    
43. select_mode.place(x="200", y="470")
    
44. 
    
45. select_mode = Label(text=h_y, font="Arial 12")
    
46. select_mode['bg'] = "grey30"
    
47. select_mode['fg'] = "white"
    
48. select_mode.place(x="220", y="470")
    
49. 
    
50. 
    
51. coord_thread = Thread(target = coordinates)
    
52. coord_thread.run()
    
53. coord_thread.join()
    
54. 
    
55. root.mainloop()

您可能不需要线程来执行此操作。

您可以使用 root.after() 重新执行坐标：

1. # other stuff as before, except the creation of these labels:
   
2. select_mode_x = Label(text=h_x, font="Arial 12")
   
3. select_mode_x['bg'] = "grey30"
   
4. select_mode_x['fg'] = "white"
   
5. select_mode_x.place(x="140", y="470")
   
6. 
   
7. select_mode_y = Label(text=h_y, font="Arial 12")
   
8. select_mode_y['bg'] = "grey30"
   
9. select_mode_y['fg'] = "white"
   
10. select_mode_y.place(x="220", y="470")
    
11. 
    
12. # Moved coordinates function down here
    
13. def coordinates():
    
14.     h_x, h_y = win32api.GetCursorPos()
    
15.     print(h_x, h_y)
    
16.     select_mode_x.config(text=h_x)
    
17.     select_mode_y.config(text=h_y)
    
18.     root.after(100, coordinates)
    
19. 
    
20. coordinates()
    
21. root.mainloop()
