It has border, label and padding properties. A border of a widget can be chosen to hide or display (with its border label), you can pick a different front/back colour for the border as well. To display such a widget at a specific location in terminal window, you need to assign `.X`, `.Y`, `.Height`, `.Width` values for each widget before send it to `.Render`.
