The create_widget() function creates a new widget of the specified named type (p_type) as a child of the specified window (p_win). The function call may, optionally, include a series of property (p_mode =SET_PROP) or user data (p_mode =SET_USER_DATA) definitions, similar to the definition list used in the create_window() function. The delete_widget() function deletes a widget created by create_widget(). The enable_widget() and disable_widget() functions enable and disable widgets, cuasing them to accept or ignore users input, and to be drawn in a manner that reflects their enabled or disabled status. The widget_method() function calls a named function (p_method) with a variable parameter list, returning an integer value (p_retval).Notallwidgetsimplementthesewidgetmethods. |

The create_widget() function returns a valid pointer to a widget structure on success, NULL on failure. The delete_widget(), enable_widget() and disable_widget() function returns zero (0) on success, non-zero on failure. |
