NAME
     XmArrowButtonGadget -- The ArrowButtonGadget widget class

SYNOPSIS
     #include <Xm/ArrowBG.h>

DESCRIPTION
     ArrowButtonGadget	consists  of  a directional arrow surrounded by a border
     shadow.  When it is selected, the shadow changes  to  give  the  appearance
     that  the ArrowButtonGadget has been pressed in. When it is unselected, the
     shadow reverts to give the appearance that the button is released, or out.

     ArrowButtonGadget holds the XmQTactivatable trait.

   Classes
     ArrowButtonGadget inherits behavior, resources, and traits from the Object,
     RectObj, and XmGadget classes.

     The class pointer is xmArrowButtonGadgetClass.

     The class name is XmArrowButtonGadget.

   New Resources
     The following table defines a set of widget resources used by the	program-
     mer  to  specify  data. The programmer can also set the resource values for
     the inherited classes to set attributes for this widget. To reference a re-
     source by name or by class in a .Xdefaults file, remove the XmN or XmC pre-
     fix and use the remaining letters. To specify one of the defined values for
     a resource in a .Xdefaults file, remove the Xm prefix and use the remaining
     letters (in either lowercase or uppercase, but include any underscores  be-
     tween  words).   The  codes  in the access column indicate if the given re-
     source can be set at creation time (C), set by using XtSetValues  (S),  re-
     trieved by using XtGetValues (G), or is not applicable (N/A).

     XmNactivateCallback
	       Specifies  a  list of callbacks that is called when the ArrowBut-
	       tonGadget is activated.	To activate the button,  press	and  re-
	       lease  BSelect while the pointer is inside the ArrowButtonGadget.
	       Activating the ArrowButtonGadget also  disarms  it.   The  reason
	       sent  by  this callback is XmCR_ACTIVATE.  This callback uses the
	       XmQTactivatable trait.

     XmNarmCallback
	       Specifies a list of callbacks that is called when  the  ArrowBut-
	       tonGadget  is armed.  To arm this widget, press BSelect while the
	       pointer is inside the ArrowButtonGadget.  The reason sent by this
	       callback is XmCR_ARM.

     XmNarrowDirection
	       Sets the arrow direction.  The values for this resource are

		  *  XmARROW_UP

		  *  XmARROW_DOWN

		  *  XmARROW_LEFT

		  *  XmARROW_RIGHT

     XmNdetailShadowThickness
	       Specifies the thickness of the inside arrow shadows. The  default
	       thickness is 2 pixels.

     XmNdisarmCallback
	       Specifies  a  list of callbacks that is called when the ArrowBut-
	       tonGadget is disarmed.  To disarm this widget, press and  release
	       BSelect	while  the pointer is inside the ArrowButtonGadget.  The
	       reason sent by this callback is XmCR_DISARM.

     XmNmultiClick
	       If a button click is followed by another button click within  the
	       time span specified by the display's multiclick time and this re-
	       source  is  set	to XmMULTICLICK_DISCARD, the second click is not
	       processed.  If this resource is	set  to  XmMULTICLICK_KEEP,  the
	       event is processed and click_count is incremented in the callback
	       structure.   When the ArrowButtonGadget is not in a menu, the de-
	       fault value is XmMULTICLICK_KEEP.

   Inherited Resources
     XmArrowButtonGadget inherits behavior and resources from  the  superclasses
     described	in the following tables.  For a complete description of each re-
     source, refer to the reference page for that superclass.

   Callback Information
     A pointer to the following structure is passed to each callback:

     typedef struct
     {
	     int reason;
	     XEvent * event;
	     int click_count;
     } XmArrowButtonCallbackStruct;

     reason    Indicates why the callback was invoked.

     event     Points to the XEvent that triggered the callback.

     click_count
	       This value is valid only when the reason  is  XmCR_ACTIVATE.   It
	       contains  the number of clicks in the last multiclick sequence if
	       the XmNmultiClick resource is set to XmMULTICLICK_KEEP, otherwise
	       it contains 1.  The activate callback is invoked for  each  click
	       if XmNmultiClick is set to XmMULTICLICK_KEEP.

   Behavior
     XmArrowButtonGadget  includes  behavior  from XmGadget.  The following list
     describes additional XmArrowButtonGadget behavior:

     <Btn1Down>:
	       Draws the shadow in the selected state and  calls  the  callbacks
	       for XmNarmCallback.

     <Btn1Down> or <Btn1Up>:
	       Draws  the  shadow  in  the  unselected state.  If the pointer is
	       within the ArrowButtonGadget, calls the	callbacks  for	XmNacti-
	       vateCallback.  Calls the callbacks for XmNdisarmCallback.

     <Btn1Down>(2+):
	       If  XmNmultiClick is XmMULTICLICK_DISCARD, this action does noth-
	       ing.  If XmNmultiClick is XmMULTICLICK_KEEP,  this  action  draws
	       the shadow in the selected state and calls the callbacks for XmN-
	       armCallback.

     <Btn1Up>(2+):
	       If  XmNmultiClick is XmMULTICLICK_DISCARD, this action does noth-
	       ing.

	       If XmNmultiClick is  XmMULTICLICK_KEEP,	this  action  increments
	       click_count in the callback structure and draws the shadow in the
	       unselected  state.   If the pointer is within the ArrowButtonGad-
	       get, this action calls the callbacks for XmNactivateCallback  and
	       XmNdisarmCallback.

     <Key><osfSelect>:
	       Draws  the  shadow  in the selected state and calls the callbacks
	       for XmNarmCallback.  Arranges for the shadow to be drawn  in  the
	       unselected  state  and  the callbacks for XmNactivateCallback and
	       XmNdisarmCallback to be called, either immediately or at a  later
	       time.

     <Key><osfHelp>:
	       Calls  the  callbacks for XmNhelpCallback if any exist.	If there
	       are no help callbacks for this widget, this action calls the help
	       callbacks for the nearest ancestor that has them.

     <Enter>:  Draws the ArrowButtonGadget shadow in its selected state  if  the
	       pointer leaves and re-enters the gadget while <Btn1> is pressed.

     <Leave>:  Draws the ArrowButtonGadget shadow in its unselected state if the
	       pointer leaves the gadget while <Btn1> is pressed.

   Virtual Bindings
     The  bindings  for virtual keys are vendor specific.  For information about
     bindings for virtual buttons and keys, see VirtualBindings(3).
