- {\bf 1. Definition}
-
- Panels are windows used for displaying text messages and updating the
- values of variables. A panel $P$ consists of a set of panel items and a set
- of buttons. With each item (except of text items) is associated a variable of
- a certain type (int, bool, string, double, color) whose value can be
- manipulated through the item and a string label.
-

- {\bf 2. Creation}
-
- \create P (string\ h)
-
- creates an empty panel $P$ with header $h$.
