XmLabelGadget(3) Library Functions Manual XmLabelGadget(3) NAME XmLabelGadget -- The LabelGadget widget class SYNOPSIS #include <Xm/LabelG.h> DESCRIPTION LabelGadget is an instantiable widget and is also used as a superclass for other button gadgets, such as PushButtonGadget and ToggleButtonGad- get. LabelGadget can contain either text or a pixmap. LabelGadget text is a compound string. Refer to the Motif Programmer's Guide for more infor- mation on compound strings. The text can be multilingual, multiline, and/or multifont. When a LabelGadget is insensitive, its text is stip- pled, or the user-supplied insensitive pixmap is displayed. LabelGadget supports both accelerators and mnemonics primarily for use in LabelGadget subclass widgets that are contained in menus. Mnemonics are available in a menu system when the button is visible. Accelerators in a menu system are accessible even when the button is not visible. The LabelGadget displays the mnemonic by underlining the first matching character in the text string. The accelerator is displayed as a text string adjacent to the label text or pixmap, depending on the layout direction. LabelGadget consists of many margin fields surrounding the text or pixmap. These margin fields are resources that may be set by the user, but LabelGadget subclasses and Manager parents also modify some of these fields. They tend to modify the XmNmarginLeft, XmNmarginRight, XmNmarginTop, and XmNmarginBottom resources and leave the XmNmargin- Width and XmNmarginHeight resources as set by the application. LabelGadget takes into account XmNshadowThickness in determining its layout but does not draw the shadow. That is, if XmNshadowThickness is greater than 0 (zero), LabelGadget leaves space for the shadow, but the shadow does not appear. In a LabelGadget, XmNtraversalOn and XmNhighlightOnEnter are forced to False inside Popup menu panes, Pulldown menu panes, and OptionMenus. Otherwise these resources default to False. LabelGadget uses the XmQTmenuSystem and XmQTspecifyRenderTable traits, and holds the XmQTaccessTextual, XmQTcareParentVisual, XmQTmenuSavvy, and XmQTtransfer traits. Data Transfer Behavior LabelGadget and it subclasses, except when used in a menu system, sup- port dragging of the label contents from the LabelGadget. However, the label contents are draggable only if the XmNenableUnselectableDrag re- source of XmDisplay is set to True. As a source of data, LabelGadget and its subclasses support the follow- ing targets and associated conversions of data to these targets: locale If the locale target matches the widget's locale, the widget transfers XmNlabelString in the encoding of the locale. This target is supported only when XmNlabelType is XmSTRING or XmPIXMAP_AND_STRING. COMPOUND_TEXT The widget transfers XmNlabelString as type COMPOUND_TEXT. This target is supported only when XmNlabelType is XmSTRING or XmPIXMAP_AND_STRING. UTF8_STRING The widget transfers XmNlabelString as type UTF8_STRING. This target is supported only when XmNlabelType is XmSTRING of XmPIXMAP_AND_STRING. PIXMAP The widget transfers XmNlabelPixmap as type DRAWABLE. This target is supported when XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING. STRING The widget transfers XmNlabelString as type STRING. This target is supported when XmNlabelType is XmSTRING or XmPIXMAP_AND_STRING. TEXT If XmNlabelString is fully convertible to the encoding of the locale, the widget transfers XmNlabelString in the encoding of the locale. Otherwise, the widget transfers XmNlabel- String as type COMPOUND_TEXT. This target is supported when XmNlabelType is XmSTRING or XmPIXMAP_AND_STRING. _MOTIF_CLIPBOARD_TARGETS The widget transfers, as type ATOM, a list of the targets it supports for the CLIPBOARD selection. When XmNlabelType is XmSTRING or XmPIXMAP_AND_STRING, these include the following targets: • _MOTIF_COMPOUND_STRING • COMPOUND_TEXT • UTF8_STRING • The encoding of the locale, if XmNlabelString is fully convertible to the encoding of the locale • STRING, if XmNlabelString is fully convertible to STRING When XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, the targets include PIXMAP. _MOTIF_COMPOUND_STRING The widget transfers XmNlabelString as a compound string in Byte Stream format. This target is supported when XmNlabel- Type is XmSTRING or XmPIXMAP_AND_STRING. _MOTIF_EXPORT_TARGETS The widget transfers, as type ATOM, a list of the targets to be used as the value of the DragContext's XmNexportTargets in a drag-and-drop transfer. When XmNlabelType is XmSTRING or XmPIXMAP_AND_STRING, these include _MOTIF_COMPOUND_STRING, COMPOUND_TEXT, UTF8_STRING, the encoding of the locale, STRING, TEXT, BACKGROUND, and FOREGROUND. When XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, these include PIXMAP, BACKGROUND, and FOREGROUND. As a source of data, LabelGadget also supports the following standard Motif targets: BACKGROUND The widget transfers the parent's XmNbackground as type PIXEL. CLASS The widget finds the first shell in the widget hierarchy that has a WM_CLASS property and transfers the contents as text in the current locale. CLIENT_WINDOW The widget finds the first shell in the widget hierarchy and transfers its window as type WINDOW. COLORMAP The widget transfers the parent's XmNcolormap as type COL- ORMAP. FOREGROUND The widget transfers the parent's XmNforeground as type PIXEL. NAME The widget finds the first shell in the widget hierarchy that has a WM_NAME property and transfers the contents as text in the current locale. TARGETS The widget transfers, as type ATOM, a list of the targets it supports. These include the standard targets in this list. When XmNlabelType is XmSTRING or XmPIXMAP_AND_STRING, these also include _MOTIF_COMPOUND_STRING, COMPOUND_TEXT, UTF8_STRING, the encoding of the locale, STRING, and TEXT. When XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING, these also include PIXMAP. TIMESTAMP The widget transfers the timestamp used to acquire the selec- tion as type INTEGER. _MOTIF_RENDER_TABLE The widget transfers XmNrenderTable if it exists, or else the default text render table, as type STRING. _MOTIF_ENCODING_REGISTRY The widget transfers its encoding registry as type STRING. The value is a list of NULL separated items in the form of tag encoding pairs. This target symbolizes the transfer tar- get for the Motif Segment Encoding Registry. Widgets and ap- plications can use this Registry to register text encoding formats for specified render table tags. Applications access this Registry by calling XmRegisterSegmentEncoding and XmMapSegmentEncoding. Classes LabelGadget inherits behavior, resources, and traits from Object, Rec- tObj and XmGadget. The class pointer is xmLabelGadgetClass. The class name is XmLabelGadget. New Resources The following table defines a set of widget resources used by the pro- grammer to specify data. The programmer can also set the resource val- ues 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). +-----------------------------------------------------------------------------------------------------------+ | | XmLabelGadget Resource Set | | | | Name | Class | Type | Default | Access | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNaccelerator | XmCAccelerator | String | NULL | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNacceleratorText | XmCAcceleratorText | XmString | NULL | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNalignment | XmCAlignment | unsigned char | dynamic | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNfontList | XmCFontList | XmFontList | dynamic | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNlabelInsensitivePixmap | XmCLabelInsensitivePixmap | Pixmap | XmUNSPECIFIED_PIXMAP | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNlabelPixmap | XmCLabelPixmap | Pixmap | XmUNSPECIFIED_PIXMAP | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNlabelString | XmCXmString | XmString | dynamic | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNlabelType | XmCLabelType | unsigned char | XmSTRING | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNmarginBottom | XmCMarginBottom | Dimension | 0 | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNmarginHeight | XmCMarginHeight | Dimension | 2 | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNmarginLeft | XmCMarginLeft | Dimension | 0 | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNmarginRight | XmCMarginRight | Dimension | 0 | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNmarginTop | XmCMarginTop | Dimension | 0 | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNmarginWidth | XmCMarginWidth | Dimension | 2 | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNmnemonic | XmCMnemonic | KeySym | NULL | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNmnemonicCharSet | XmCMnemonicCharSet | String | dynamic | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNpixmapPlacement | XmCPixmapPlacement | unsigned int | XmPIXMAP_LEFT | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNpixmapTextPadding | XmCSpace | Dimension | 2 | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNrecomputeSize | XmCRecomputeSize | Boolean | True | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNrenderTable | XmCRenderTable | XmRenderTable | dynamic | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ | XmNstringDirection | XmCStringDirection | XmStringDirection | dynamic | CSG | +---------------------------+---------------------------+-------------------+----------------------+--------+ +---------------------------+---------------------------+-------------------+----------------------+--------+ XmNaccelerator Sets the accelerator on a button widget in a menu, which ac- tivates a visible or invisible, but managed, button from the keyboard. This resource is a string that describes a set of modifiers and the key that may be used to select the button. The format of this string is identical to that used by the translations manager, with the exception that only a single event may be specified and only KeyPress events are allowed. Accelerators for buttons are supported only for PushButton- Gadgets and ToggleButtonGadgets in Pulldown and Popup menus. XmNacceleratorText Specifies the text displayed for the accelerator. The text is displayed adjacent to the label string or pixmap. The di- rection of its layout depends on the XmNlayoutDirection re- source of the widget. Accelerator text for buttons is dis- played only for PushButtonGadgets and ToggleButtonGadgets in Pulldown and Popup Menus. XmNalignment Specifies the label alignment for text or pixmap. XmALIGNMENT_BEGINNING (left alignment) Causes the left sides of the lines of text to be vertically aligned with the left edge of the gad- get. For a pixmap, its left side is vertically aligned with the left edge of the gadget. XmALIGNMENT_CENTER (center alignment) Causes the centers of the lines of text to be ver- tically aligned in the center of the gadget. For a pixmap, its center is vertically aligned with the center of the gadget. XmALIGNMENT_END (right alignment) Causes the right sides of the lines of text to be vertically aligned with the right edge of the gad- get. For a pixmap, its right side is vertically aligned with the right edge of the gadget. The preceding descriptions for text are correct when XmNlay- outDirection is XmLEFT_TO_RIGHT. When that resource is Xm- RIGHT_TO_LEFT, the descriptions for XmALIGNMENT_BEGINNING and XmALIGNMENT_END are switched. If the parent is a RowColumn whose XmNisAligned resource is True, XmNalignment is forced to the same value as the RowCol- umn's XmNentryAlignment if the RowColumn's XmNrowColumnType is XmWORK_AREA or if the gadget is a subclass of XmLabelGad- get. Otherwise, the default is XmALIGNMENT_CENTER. XmNfontList Specifies the font of the text used in the gadget. XmN- fontList is obsolete and exists for compatibility with previ- ous releases. You should now use XmNrenderTable instead of XmNfontList. If both are specified, the render table will take precedence. If XmNfontList is NULL at initialization, the parent hierarchy of the widget is searched for an ances- tor that is a subclass of the XmBulletinBoard, VendorShell, or XmMenuShell widget class. If such an ancestor is found, the font list is initialized to the XmNbuttonFontList (for button gadget subclasses) or XmNlabelFontList of the ancestor widget. If no such ancestor is found, the default is imple- mentation dependent. Refer to XmFontList(3) for more informa- tion on the creation and structure of a font list. XmNlabelInsensitivePixmap Specifies a pixmap used as the button face if XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING and the button is insensi- tive. The default value, XmUNSPECIFIED_PIXMAP, displays an empty label. XmNlabelPixmap Specifies the pixmap when XmNlabelType is XmPIXMAP or XmPIXMAP_AND_STRING. The default value, XmUNSPECI- FIED_PIXMAP, displays an empty label. XmNlabelString Specifies the compound string when XmNlabelType is XmSTRING or XmPIXMAP_AND_STRING. If the value of this resource is NULL, it is initialized to name of the gadget converted to a compound string. Refer to XmString(3) for more information on the creation and the structure of compound strings. XmNlabelType Specifies the label type. XmSTRING Text displays XmNlabelString XmPIXMAP Icon data in pixmap displays XmNlabelPixmap or XmN- labelInsensitivePixmap XmPIXMAP_AND_STRING Icon data in pixmap displays XmNlabelPixmap or XmNla- belInsensitivePixmap and text displays XmNlabel- String XmNmarginBottom Specifies the amount of spacing between the bottom of the la- bel text and the top of the bottom margin specified by XmN- marginHeight. This may be modified by LabelGadget's sub- classes. For example, CascadeButtonGadget may increase this field to make room for the cascade pixmap. XmNmarginHeight Specifies an equal amount of spacing above the margin defined by XmNmarginTop and below the margin defined by XmNmarginBot- tom. XmNmarginHeight specifies the amount of spacing between the top edge of the margin set by XmNmarginTop and the bottom edge of the top shadow, and the amount of spacing between the bottom edge of the margin specified by XmNmarginBottom and the top edge of the bottom shadow. XmNmarginLeft Specifies the amount of spacing between the left edge of the label text and the right side of the left margin (specified by XmNmarginWidth). This may be modified by LabelGadget's subclasses. For example, ToggleButtonGadget may increase this field to make room for the toggle indicator and for spacing between the indicator and label. Whether this actu- ally applies to the left or right side of the label depends on the value of XmNlayoutDirection. XmNmarginRight Specifies the amount of spacing between the right edge of the label text and the left side of the right margin (specified by XmNmarginWidth). This may be modified by LabelGadget's subclasses. For example, CascadeButtonGadget may increase this field to make room for the cascade pixmap. Whether this actually applies to the left or right side of the label de- pends on the value of XmNlayoutDirection. XmNmarginTop Specifies the amount of spacing between the top of the label text and the bottom of the top margin specified by XmNmargin- Height. This may be modified by LabelGadget's subclasses. For example, CascadeButtonGadget may increase this field to make room for the cascade pixmap. XmNmarginWidth Specifies an equal amount of spacing to the left of the mar- gin defined by XmNmarginLeft and to the right of the margin defined by XmNmarginRight. XmNmarginWidth specifies the amount of spacing between the left edge of the margin set by XmNmarginLeft and the right edge of the left shadow, and the amount of spacing between the right edge of the margin speci- fied by XmNmarginRight and the left edge of the right shadow. XmNmnemonic Provides the user with an alternate means of activating a button. A button in a MenuBar, a Popup menu pane, or a Pull- down menu pane can have a mnemonic. This resource contains a keysym as listed in the X11 keysym table. The first character in the label string that exactly matches the mnemonic in the character set specified in XmNm- nemonicCharSet is underlined when the button is displayed. When a mnemonic has been specified, the user activates the button by pressing the mnemonic key while the button is visi- ble. If the button is a CascadeButtonGadget in a MenuBar and the MenuBar does not have the focus, the user must use the MAlt modifier while pressing the mnemonic. The user can ac- tivate the button by pressing either the shifted or the un- shifted mnemonic key. XmNmnemonicCharSet Specifies the character set of the mnemonic for the label. The default is XmFONTLIST_DEFAULT_TAG. XmNpixmapPlacement The location of the pixmap with respect to the text label. This resource can take one of the following values: XmPIXMAP_TOP, XmPIXMAP_BOTTOM, XmPIXMAP_LEFT, and XmPIXMAP_RIGHT. A type converter has been registered that converts the following strings: "top", "bottom", "left", and "right". XmNpixmapTextPadding The amount of space to be left between the pixmap and the la- bel string. XmNrecomputeSize Specifies a Boolean value that indicates whether the gadget shrinks or expands to accommodate its contents (label string or pixmap) as a result of an XtSetValues resource value that would change the size of the gadget. If True, the gadget shrinks or expands to exactly fit the label string or pixmap. If False, the gadget never attempts to change size on its own. XmNrenderTable Specifies the render table associated with the labelString. If this value is NULL at initialization, Label searches its parent hierarchy for an ancestor that holds the XmQTspeci- fyRenderTable trait. If such an ancestor is found, Label initializes XmNrenderTable to the XmLABEL_RENDER_TABLE value of the ancestor widget. Similarly, button subclasses of Label initialize XmNrenderTable to the XmBUTTON_RENDER_TABLE value of the ancestor widget. (Note that all current subclasses of Label are button subclasses.) If no such ancestor is found, the default is implementation dependent. If a font list and a render table are both specified, the render table will take precedence. Refer to XmRenderTable(3) for more information on the creation and structure of a render table. XmNstringDirection Is a synthetic resource for setting XmNlayoutDirection. The values for this resource are XmSTRING_DIRECTION_L_TO_R and XmSTRING_DIRECTION_R_TO_L. Refer to the XmNlayoutDirection resource description. The XmNstringDirection resource is ob- soleted by XmNlayoutDirection, but is kept here for backward compatibility. Inherited Resources LabelGadget inherits behavior and resources from the superclasses de- scribed in the following tables.

XmGadget. Additional XmLabelGad- get behavior is described in the following list: <Btn2Down>: Drags the contents of a LabelGadget, identified when BTrans- fer is pressed. This action is undefined for LabelGadgets used in a menu system. <Key><osfHelp>: In a Popup or Pulldown MenuPane, unposts all menus in the menu hierarchy and, when the shell's keyboard focus policy is XmEXPLICIT, restores keyboard focus to the widget that had the focus before the menu system was entered. 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. <key><osfCancel>: In a MenuBar, disarms the CascadeButton and the menu and, when the shell's keyboard focus policy is XmEXPLICIT, re- stores keyboard focus to the widget that had the focus before the menu was entered. In a toplevel Pulldown MenuPane from a MenuBar, unposts the menu, disarms the MenuBar CascadeButton and the MenuBar, and, when the shell's keyboard focus policy is XmEXPLICIT, re- stores keyboard focus to the widget that had the focus before the MenuBar was entered. In other Pulldown MenuPanes, un- posts the menu. In a Popup MenuPane, unposts the menu and, when the shell's keyboard focus policy is XmEXPLICIT, restores keyboard focus to the widget from which the menu was posted. <Key><osfDown>: If the current menu item has a submenu and is in a MenuBar, then this action posts the submenu, disarms the current menu item, and arms the submenu's first traversable menu item. If the current menu item is in a MenuPane, then this action disarms the current menu item and arms the item below it. This action wraps within the MenuPane. The direction of the wrapping depends on the XmNlayoutDirection resource. <Key><osfLeft>: When the current menu item is in a MenuBar, then this action disarms the current item and arms the MenuBar item to the left. This action wraps within the MenuBar. In MenuPanes, if the current menu item is not at the left edge of a MenuPane, this action disarms the current item and arms the item to its left. If the current menu item is at the left edge of a submenu attached to a MenuBar item, then this action unposts the submenu and traverses to the MenuBar item to the left, wrapping if necessary. If that MenuBar item has a submenu, it posts the submenu and arms the first tra- versable item in the submenu. If the current menu item is at the left edge of a submenu not directly attached to a MenuBar item, then this action unposts the current submenu only. In Popup or Torn-off MenuPanes, when the current menu item is at the left edge, this action wraps within the MenuPane. If the current menu item is at the left edge of the MenuPane and not in the top row, this action wraps to the rightmost menu item in the row above. If the current menu item is in the up- per, leftmost corner, this action wraps to the tear-off con- trol, if present, or else it wraps to the bottom, rightmost menu item in the MenuPane. The preceding description applies when the XmNlayoutDirection horizontal direction is Xm- LEFT_TO_RIGHT. If the XmNlayoutDirection horizontal direction is XmRIGHT_TO_LEFT, then the following applies. If the current menu item is in a MenuBar, then this action disarms the current item and arms the MenuBar item to the left. This action wraps within the MenuBar. In MenuPanes, if the current menu item is a CascadeButton, then this action posts its associated submenu. If the cur- rent menu item is not a CascadeButton and is not at the left edge of a MenuPane, this action disarms the current item and arms the item to its left, wrapping if necessary. If the current menu item is not a CascadeButton and is at the left edge of a submenu that is a descendent of a MenuBar, then this action unposts all submenus and traverses to the MenuBar item to the left. If that MenuBar item has a submenu, it posts the submenu and arms the submenu's first traversable item. In Popup or Torn-off menus, if the current menu item is not a CascadeButton and is at the left edge of a row (except the bottom row), this action wraps to the rightmost menu item in the row below. If the current menu item is not a CascadeBut- ton and is in the bottom, leftmost corner of a Popup or Pull- down MenuPane, this action wraps to the tear-off control, if present, or else it wraps to the top, rightmost menu item of the MenuPane. <Key><osfRight>: If the current menu item is in a MenuBar, then this action disarms the current item and arms the MenuBar item to the right. This action wraps within the MenuBar. In MenuPanes, if the current menu item is a CascadeButton, then this action posts its associated submenu. If the cur- rent menu item is not a CascadeButton and is not at the right edge of a MenuPane, this action disarms the current item and arms the item to its right, wrapping if necessary. If the current menu item is not a CascadeButton and is at the right edge of a submenu that is a descendent of a MenuBar, then this action unposts all submenus and traverses to the MenuBar item to the right. If that MenuBar item has a submenu, it posts the submenu and arms the submenu's first traversable item. In Popup or Torn-off menus, if the current menu item is not a CascadeButton and is at the right edge of a row (except the bottom row), this action wraps to the leftmost menu item in the row below. If the current menu item is not a CascadeBut- ton and is in the bottom, rightmost corner of a Popup or Pulldown MenuPane, this action wraps to the tear-off control, if present, or else it wraps to the top, leftmost menu item of the MenuPane. The preceding description applies when the XmNlayoutDirection horizontal direction is XmLEFT_TO_RIGHT. If the XmNlayoutDirection horizontal direction is Xm- RIGHT_TO_LEFT, then the following applies. When the current menu item is in a MenuBar, then this action disarms the current item and arms the MenuBar item to the right. This action wraps within the MenuBar. In MenuPanes, if the current menu item is not at the right edge of a MenuPane, this action disarms the current item and arms the item to its right. If the current menu item is at the right edge of a submenu attached to a MenuBar item, then this action unposts the submenu and traverses to the MenuBar item to the right, wrapping if necessary. If that MenuBar item has a submenu, it posts the submenu and arms the first traversable item in the submenu. If the current menu item is at the right edge of a submenu not directly attached to a MenuBar item, then this action unposts the current submenu only. In Popup or Torn-off MenuPanes, when the current menu item is at the right edge, this action wraps within the MenuPane. If the current menu item is at the right edge of the MenuPane and not in the top row, this action wraps to the leftmost menu item in the row above. If the current menu item is in the upper, rightmost corner, this action wraps to the tear- off control, if present, or else it wraps to the bottom, leftmost menu item in the MenuPane. <Key><osfUp>: When the current menu item is in a MenuPane, then this action disarms the current menu item and arms the item above it. This action wraps within the MenuPane. The direction of the wrapping depends on the XmNlayoutDirection resource. Virtual Bindings The bindings for virtual keys are vendor specific.
