DwtRadioBox(3Dwt)														 DwtRadioBox(3Dwt)

Name
       DwtRadioBox, DwtRadioBoxCreate - Creates a radio box widget for the application to display multiple toggle buttons.

Syntax
       Widget DwtRadioBox(parent_widget, name, x, y,
			  entry_callback, help_callback)
	    Widget parent_widget;
	    char *name;
	    Position x, y;
	    DwtCallbackPtr entry_callback, help_callback;

       Widget DwtRadioBoxCreate (parent_widget, name,
				 override_arglist, override_argcount)
	    Widget parent_widget;
	    char *name;
	    ArgList override_arglist;
	    int override_argcount;

Arguments
       parent_widget
		 Specifies the parent widget ID.

       name	 Specifies the name of the created widget.

       x	 Specifies  the  placement, in pixels, of the left side of the widget window relative to the inner upper left corner of the parent
		 window.  This argument sets the DwtNx core widget attribute.

       y	 Specifies, in pixels, the placement of the upper left corner of the widget window relative to the inner upper left corner of  the
		 parent window.  This argument sets the DwtNy core widget attribute.

       entry_callback
		 If  this  callback  is  defined,  all menu entry activation callbacks are revectored to call back through this callback.  If this
		 callback is NULL, the individual menu entry callbacks work as usual.  For this callback, the reason is DwtCRActivate.	This argu-
		 ment sets the DwtNentryCallback attribute associated with DwtMenuCreate.

       help_callback
		 Specifies  the callback function or functions called when a help request is made.  This argument sets the DwtNhelpCallback common
		 widget attribute.

       override_arglist
		 Specifies the application override argument list.

       override_argcount
		 Specifies the number of attributes in the application override argument list (override_arglist).

Description
       The radio box is a composite widget that contains multiple toggle button widgets.  The radio box arbitrates and ensures that only one  tog-
       gle  button is on at any one given time.  When calling DwtRadioBox, you set the radio box widget attributes presented in the formal parame-
       ter list.  For DwtRadioBoxCreate, however, you specify a list of attribute name/value pairs that represent all the possible radio box  wid-
       get attributes.	After you create an instance of this widget, you can manipulate it using the appropriate X intrinsics functions.

Return Values
       These functions return the ID of the created widget.

Callback Information
       The following structure is returned to your callback:
       typedef struct {
			    int reason;
			    XEvent *event;
			    Widget s_widget;
			    char *s_tag;
			    char *s_callbackstruct;
       } DwtRadioBoxCallbackStruct;
       The  reason member is set to a constant that represents the reason why this callback was invoked.  For this callback, the reason member can
       be set to:

       DwtCRValueChanged    The  user  activated  the
			    toggle  button  to change
			    state.

       DwtCRMap 	    The radio box is about to
			    be mapped.

       DwtCRHelpRequested   The user selected Help.

       The  event  member  is a pointer to the Xlib structure XEvent, which describes the event that generated this callback.  This structure is a
       union of the individual structures declared for each event type.  For information on XEvent and event processing, see the Guide to the Xlib
       Library:  C  Language  Binding.	The s_widget member is set to the ID of the activating subwidget.  The s_tag member is set to the tag sup-
       plied by the application programmer when the subwidget callback function was specified.	The s_callbackstruct member is set to the  subwid-
       get's callback structure.
