如何在 Tkinter 中获得带有滚动条的框架? [英] How could I get a Frame with a scrollbar in Tkinter?

问题描述

我想要一个 Frame，用户可以在其中根据应用程序的需要添加尽可能多的文本字段.

I'd like to have a Frame, where the user could add as many textfields as needed by the application.

应用程序以一个文本字段和该文本字段下方的按钮开始.当用户按下按钮时，将在第一个下方添加一个新的文本条目(这可能会重复无数次).在窗口中间，会有一个 Text 小部件，用于显示文本 :)

The application starts with a textfield, and a button below that textfield. When the user presses the button, a new text entry will be added below the first one ( this may be repeated countless times ). In the middle of the window, there will be a Text widget, used to display text :)

但是，我在文档中注意到了这一点:

However, I noticed this in the documentation:

此小部件用于实现滚动列表框、画布和文本字段.

有没有办法将 Scrollbar 与 Frame 一起使用?

Is there a way to use the Scrollbar with a Frame?

推荐答案

如果你可以使用 Tix，有一个 ScrolledWindow 小部件，它有一个 window Frame 和一两个 Scrollbar 小部件:

If you can use Tix, there is the ScrolledWindow widget which has a window Frame and one or two Scrollbar widgets:

import Tix as tk

r= tk.Tk()
r.title("test scrolled window")
sw= tk.ScrolledWindow(r, scrollbar=tk.Y) # just the vertical scrollbar
sw.pack(fill=tk.BOTH, expand=1)
for i in xrange(10):
    e= tk.Entry(sw.window)
    e.pack()
r.mainloop()

改变根窗口的大小.您需要向 Entry 小部件的 focus_get 事件添加代码，以便在通过键盘进行 Tab 键切换时滚动 ScrolledWindow.

Change the size of the root window. You will want to add code to the focus_get event of the Entry widgets to scroll the ScrolledWindow when tabbing through the keyboard.

否则，您将不得不使用 Canvas 小部件(您可以添加标签、条目和文本子小部件)并自己编写更多代码来实现您所需的功能.

Otherwise, you will have to use a Canvas widget (you can add Label, Entry and Text subwidgets) and write a lot more code yourself to implement your required functionality.
