Tkinter-画布文本对象自动滚动

Question

I'm working on a Tkinter application with a Canvas and a create_text object drawn on top of this Canvas .

This text object word wraps automatically through the width property. However, I would like this text to automatically clip the top line of the text when the text object wraps to a 4th line.

So go from this:

 aaaa
bbbbbb
 cccc
dddddd <- incoming new text

To this:

bbbbbb
 cccc
dddddd

Any good way to do this?

No, there is no way to cause canvas text items to clip the way you want.

Answer 2

You can simply scroll the Text widget.
