The private header file includes the private header file of its superclass, thereby exposing the
entire internal structure of the widget. It may not always be advantageous to do this; your own
project development style will dictate the appropriate levelofdetail to expose in each module.
The ‘‘WindowWidget’’needs to declare twofields in its instance structure to hold the drawing
colors, a resource field for the font and a field for the expose and user input callback lists:
typedef struct {
/* resources */
Pixel color_1;
Pixel color_2;
XFontStruct* font;
XtCallbackList expose_callback;
XtCallbackList input_callback;
/* private state */
/* (none) */
}WindowPart;
7.3. Widget Source File
The source code file implements the widget class itself. The unique part of this file is the declara-
tion and initialization of the widget class record structure and the declaration of all resources and
action routines added by the widget class.
The contents of the Template implementation file, <X11/Xaw/Template.c>, are:
