Detailed Description

The generic CTK widget structure that contains all other widget structures.

Since the widgets of a window are arranged on a linked list, the widget structure contains a next pointer which is used for this purpose. The widget structure also contains the placement and the size of the widget.

Finally, the actual per-widget structure is contained in this top-level widget structure.
