\"It would be very useful to be able to attach a \"\"Line Frame\"\" to the window border. This would mean that if the form was resized, or maximised, the line frame would stretch to the new size of the form.

\"There could be properties against the \"\"Line Frame\"\" widget which would allow you to attach it to the window borders. There wouls also be a checkbox to identify whether it should be 3D or not.\"
