Question

我在使用某些代码时遇到了麻烦，我想在屏幕上滚动一组小部件，但滚动条无法正常工作。我已经附上了结果的图片和下面的代码，我使用的是python tkinter，namesfile.txt仅包含人员列表。

tkinter import *


Y_level=10

people = []

f = open("namefile.txt", "r")
for people_in_file in f:
    people.append(people_in_file)

parent = Tk()

canvas = Canvas(parent)
scroll_y = Scrollbar(parent, orient="vertical", command=canvas.yview)

frame = Frame(canvas)

for person in people:
    label_name='person: '+person    
    print(label_name)
    print(Y_level)
    
    
    label_name = Label(parent, text=person)
    label_name.place(x=10, y=Y_level)
    Y_level=Y_level+20

canvas.create_window(0, 0, anchor='nw', window=frame)

canvas.update_idletasks()

canvas.configure(scrollregion=canvas.bbox('all'), 
                 yscrollcommand=scroll_y.set)

canvas.pack(fill='both', expand=True, side='left')
scroll_y.pack(fill='y', side='right')
    
parent.mainloop()

Answer 1

首先，您应该将标签放在frame而不是parent内。其次，您应该使用pack()而不是place()，因为place()不会扩展父容器。

for person in people:
    label_name='person: '+person    
    print(label_name)
    label_name = Label(frame, text=person)
    label_name.pack()

tkinter滚动多个小部件
