NAME

       XtCreateApplicationContext, XtDestroyApplicationContext, XtWidgetToApplicationContext,
       XtToolkitInitialize - create, destroy, and obtain an application context

SYNTAX

       #include <X11/Intrinsic.h>

       XtAppContext XtCreateApplicationContext(void);

       void XtDestroyApplicationContext(XtAppContext app_context);

       XtAppContext XtWidgetToApplicationContext(Widget w);

       void XtToolkitInitialize(void);

ARGUMENTS

       app_context
                 Specifies the application context.

       w         Specifies the widget that you want the application context for.

DESCRIPTION

       The XtCreateApplicationContext function returns an application context, which is an opaque
       type.  Every application must have at least one application context.

       The XtDestroyApplicationContext function destroys the specified application context as
       soon as it is safe to do so.  If called from with an event dispatch (for example, a
       callback procedure), XtDestroyApplicationContext does not destroy the application context
       until the dispatch is complete.

       The XtWidgetToApplicationContext function returns the application context for the
       specified widget.

       The XtToolkitInitialize function initializes the Intrinsics internals.  If
       XtToolkitInitialize was previously called it returns immediately.
