推荐答案

您的选择取决于您真正要实现的目标。为什么使用画布比使用框架更好？

Your choices depend on what you're really trying to accomplish. Why is using a canvas preferable to using a frame?

您可以像使用包装盒，网格或放置容器一样轻松地将小部​​件添加到画布中。这样做时，滚动画布时这些项目将不会滚动，因为它们实际上并不是画布的一部分。

You can easily add widgets to a canvas just like you do any other container, using pack or grid or place. when you do this, the items will not scroll when you scroll the canvas because they aren't actually part of the canvas.

另一种选择是在窗口上创建窗口对象画布。您可以使用画布的 create_window 方法执行此操作。优点是，此窗口成为画布的一部分，并将与画布上的任何其他对象一起滚动。缺点是，您唯一的选择是绝对放置，您必须显式控制小部件的大小。

The other choice is to create window objects on the canvas. You do this with the create_window method of the canvas. The advantage is, this window becomes part of the canvas and will scroll along with any other objects on the canvas. The downside is, your only option is absolute placement and you have to explicitly control the size of the widgets.
