borderWidth can change the 4 borders (top, bottom, left, right) width of objects, like TextField.

How to change one of borders (say left border) width of TextField?

I want the border width is different for each border.

On the Border palette, choose "Edit Individually" instead of (the default) "Edit Together" for the Edges property. This will allow you to change individual widths and colors.
