DtHelpReturnSelectedWidgetId(library call)								DtHelpReturnSelectedWidgetId(library call)

NAME

       DtHelpReturnSelectedWidgetId -- select a widget or gadget

SYNOPSIS

       #include <Dt/Help.h>
       int DtHelpReturnSelectedWidgetId(
       Widget parent,
       String cursor,
       Widget *widget);

DESCRIPTION

       The DtHelpReturnSelectedWidgetId function provides an interface for users to select a component within an application.

       This function grabs the pointer and returns the widget within which a button press occurs.  Pressing the escape key (ESC) aborts this func-
       tion.

       The parent argument specifies the widget ID to use as the basis of the interaction, usually a top level shell.

       The cursor argument specifies the cursor to be used for the pointer during the interaction.  If a NULL value is used, DtHelpReturnSelected-
       WidgetId uses a default cursor value.

       The widget argument is the return value (for example, the selected widget).  A NULL value is returned on error.

       The DtHelpReturnSelectedWidgetId function allows applications to get the widget ID for any widget in their user interface that the user has
       selected via the pointer.  The application can then directly display a help topic based on the selected widget,	or  dynamically  construct
       some  help  information	based  on the current context of the selected item.  At any point while the question mark cursor is displayed, the
       user can select the escape key to abort the function call, and a NULL value is returned.  If the user selects any item outside the  current
       applications windows, an error status is returned along with a NULL value for the widget argument.  Refer to XmTrackingLocate(3) for a sim-
       ilar function.

RETURN VALUE

       Upon successful completion, the DtHelpReturnSelectedWidgetId function returns one of the following status values:

       DtHELP_SELECT_ERROR
		 An error occurred while attempting to process the function.

       DtHELP_SELECT_INVALID
		 The user selected an invalid component that is not contained in the current widget hierarchy.

       DtHELP_SELECT_ABORT
		 The user aborted the function (for example, pressed the escape key), and a NULL widget value is passed back.

       DtHELP_SELECT_VALID
		 The user selected a valid component within the application, and the widget argument is the ID of the selected component.

NAME

       XtNameToWidget, XtWindowToWidget - translating strings to widgets or widgets to windows

SYNTAX

       Widget XtNameToWidget(Widget reference, String names);

       Widget XtWindowToWidget(Display *display, Window window);

ARGUMENTS

       display	 Specifies the display on which the window is defined.

       names	 Specifies the fully qualified name of the desired widget.

       reference Specifies the widget from which the search is to start.

       window	 Specify the window for which you want the widget.

DESCRIPTION

       The XtNameToWidget function looks for a widget whose name is the first component in the specified names and that is a pop-up child of ref-
       erence (or a normal child if reference is a subclass of compositeWidgetClass).  It then uses that widget as the new reference and repeats
       the search after deleting the first component from the specified names.	If it cannot find the specified widget, XtNameToWidget returns
       NULL.

       Note that the names argument contains the name of a widget with respect to the specified reference widget and can contain more than one
       widget name (separated by periods) for widgets that are not direct children of the specified reference widget.

       If more than one child of the reference widget matches the name, XtNameToWidget can return any of the children.	The Intrinsics do not
       require that all children of a widget have unique names.  If the specified names contain more than one component and if more than one child
       matches the first component, XtNameToWidget can return NULL if the single branch that it follows does not contain the named widget.  That
       is, XtNameToWidget does not back up and follow other matching branches of the widget tree.

       The XtWindowToWidget function translates the specified window and display pointer into the appropriate widget instance.
