python-3.x - 如何在 Tkinter 中获得水平滚动条？

Question

我目前正在学习 Tkinter。从我的书中，我得到了以下用于生成简单垂直滚动条的代码:

from tkinter import * # Import tkinter

class ScrollText:
    def __init__(self):
        window = Tk() # Create a window
        window.title("Scroll Text Demo") # Set title

        frame1 = Frame(window)
        frame1.pack()
        scrollbar = Scrollbar(frame1)
        scrollbar.pack(side = RIGHT, fill = Y)
        text = Text(frame1, width = 40, height = 10, wrap = WORD,
                    yscrollcommand = scrollbar.set)
        text.pack()
        scrollbar.config(command = text.yview)

        window.mainloop() # Create an event loop

ScrollText() # Create GUI

产生以下不错的输出:

但是，当我尝试以明显的方式更改此代码以获得水平滚动条时，它会产生一个奇怪的输出。这是我正在使用的代码

from tkinter import * # Import tkinter

class ScrollText:
    def __init__(self):
        window = Tk() # Create a window
        window.title("Scroll Text Demo") # Set title

        frame1 = Frame(window)
        frame1.pack()
        scrollbar = Scrollbar(frame1)
        scrollbar.pack(side = BOTTOM, fill = X)
        text = Text(frame1, width = 40, height = 10, wrap = WORD,
                    xscrollcommand = scrollbar.set)
        text.pack()
        scrollbar.config(command = text.xview)

        window.mainloop() # Create an event loop

ScrollText() # Create GUI

这是我运行时得到的结果:

您正在分配水平滚动，xscrollcommand , 到垂直 scrollbar .您需要修改 Scrollbar 的 orient选项 'horizontal'默认情况下是 'vertical' .

尝试更换:

scrollbar = Scrollbar(frame1)

和:

scrollbar = Scrollbar(frame1, orient='horizontal')
