Question

我真的是TK库的新手。我有以下代码，但是水平滚动条没有显示。谁能看到原因？任何帮助表示赞赏！

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
container = ttk.Frame(root)
canvas = tk.Canvas(container)
scrollbar_y = ttk.Scrollbar(container, orient="vertical", command=canvas.yview)
scrollbar_x = ttk.Scrollbar(container, orient="horizontal", command=canvas.xview)
scrollable_frame = ttk.Frame(canvas)

scrollable_frame.bind(
    "<Configure>",
    lambda e: canvas.configure(
        scrollregion=canvas.bbox("all")
    )
)

canvas.create_window((0, 0), window=scrollable_frame, anchor="nw")

canvas.configure(yscrollcommand=scrollbar_y.set, xscrollcommand=scrollbar_x.set)

for i in range(50):
    ttk.Label(scrollable_frame, text="Sample scrolling label").pack()

container.pack()
canvas.pack(side="left", fill="both", expand=True)
scrollbar_y.pack(side="right", fill="y")
scrollbar_x.pack(side="bottom", fill="x")

root.mainloop()

问题已解决：

必须替换

self.x_scrollbar = Scrollbar(self.container, orient="horizontal", command=self.canvas.xview)

与

self.x_scrollbar = Scrollbar(self.master, orient="horizontal", command=self.canvas.xview)

以便滚动条可以显示在底部而不是被埋在框架中。

Python TK库水平滚动条未显示
