Textbox Border Change on Focus

I’m looking for a way to highlight or alter the border of a textbox while the mouse is hovered over the particular textbox?

I’ve used toBorder functions in expression bindings but for a textbox that will not work in the script. What else could I use?

Import BorderFactory in a project library script and call its static methods from your events.

In the Library:

from javax.swing import BorderFactory

In your event:

event.source.border = someLibScript.BorderFactory.createSomeBorder(...)
