Detailed Description

Representation of a CTK window.

For the CTK, each window is repessented by a ctk_window structure. All open windows are kept on a doubly linked list, linked by the next and prev fields in the ctk_window struct. The window structure holds all widgets that is contained in the window as well as a pointer to the currently selected widget.
