I'm wondering if it's possible to change the border color of a tkinter entry widget border. I don't think it is, because no such option exists in relevant documentation. You can change the width, but that just results in the whitespace being recessed - creating a raised 3d border.
If it can't be done, would it be more valid to use a frame around the widget? Is it possible to combine the border width and a frame to create a good appearance?
