FreeBSD Library Functions Manual |
XmArrowButton(3) |
XmArrowButton — The ArrowButton widget class
ArrowButton consists of a directional arrow surrounded by a border
shadow. When it is selected, the shadow changes to give the appearance that
the ArrowButton has been pressed in. When the ArrowButton is unselected, the
shadow reverts to give the appearance that the ArrowButton is released, or
out.
ArrowButton holds the XmQTactivatable trait.
ArrowButton inherits behavior, resources, and traits from the
Core and XmPrimitive classes.
The class pointer is xmArrowButtonWidgetClass.
The class name is XmArrowButton.
The following table defines a set of widget resources used by the
programmer to specify data. The programmer can also set the resource values
for the inherited classes to set attributes for this widget. To reference a
resource by name or by class in a .Xdefaults file, remove the
XmN or XmC prefix 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 between words). The codes in the
access column indicate if the given resource can be set at creation time
(C), set by using XtSetValues (S), retrieved by using
XtGetValues (G), or is not applicable (N/A).

- XmNactivateCallback
- Specifies a list of callbacks that is called when the ArrowButton is
activated. To activate the button, press and release BSelect while
the pointer is inside the ArrowButton widget. Activating the ArrowButton
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 ArrowButton is
armed. To arm this widget, press BSelect while the pointer is
inside the ArrowButton. 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 ArrowButton is
disarmed. To disarm this widget, press and release BSelect while
the pointer is inside the ArrowButton. The reason for 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 resource 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
button is not in a menu, the default value is
XmMULTICLICK_KEEP.
ArrowButton inherits behavior and resources from the superclasses
described in the following table. For a complete description of each
resource, refer to the reference page for that superclass.

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.
XmArrowButton includes translations for XmPrimitive. The following
key names are listed in the X standard key event translation table syntax.
This format is the one used by Motif to specify the widget actions
corresponding to a given key. A brief overview of the format is provided
under VirtualBindings(3). For a complete description of the format,
please refer to the X Toolkit Instrinsics Documentation.

The XmArrowButton action routines are
- Activate():
- Draws the shadow in the unselected state. If the pointer is within the
ArrowButton, calls the callbacks for XmNactivateCallback.
- Arm():
- Draws the shadow in the selected state and calls the callbacks for
XmNarmCallback.
- ArmAndActivate():
- 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.
- ButtonTakeFocus():
- Causes the ArrowButton to take keyboard focus when
Ctrl<Btn1Down> is pressed, without activating the
widget.
- Disarm():
- Draws the shadow in the unselected state and calls the callbacks for
XmNdisarmCallback.
- Help():
- 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.
- MultiActivate():
- If XmNmultiClick is XmMULTICLICK_DISCARD, this action does
nothing.
-
- 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 ArrowButton,
this action calls the callbacks for XmNactivateCallback and
XmNdisarmCallback.
- MultiArm():
- If XmNmultiClick is XmMULTICLICK_DISCARD, this action does
nothing. If XmNmultiClick is XmMULTICLICK_KEEP, this action
draws the shadow in the selected state and calls the callbacks for
XmNarmCallback.
This widget has the following additional behavior:
- <EnterWindow>:
- Draws the ArrowButton shadow in its selected state if the pointer leaves
and re-enters the window while <Btn1> is pressed.
- <LeaveWindow>:
- Draws the ArrowButton shadow in its unselected state if the pointer leaves
the window while <Btn1> is pressed.
