NAME [Toc] [Back]
XmLabelGadget - The LabelGadget widget class
SYNOPSIS [Toc] [Back]
#include <Xm/LabelG.h>
DESCRIPTION [Toc] [Back]
LabelGadget is an instantiable widget and is also used as a superclass
for other button gadgets, such as PushButtonGadget and
ToggleButtonGadget.
LabelGadget can contain either text or a pixmap. LabelGadget text is a
compound string. Refer to the Motif Programmer's Guide for more
information on compound strings. The text can be multilingual,
multiline, and/or multifont. When a LabelGadget is insensitive, its
text is stippled, 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 XmNmarginWidth 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 [Toc] [Back]
LabelGadget and it subclasses, except when used in a menu system,
support dragging of the label contents from the LabelGadget. However,
- 1 - Formatted: January 24, 2005
XmLabelGadget(library call) XmLabelGadget(library call)
the label contents are draggable only if the XmNenableUnselectableDrag
resource of XmDisplay is set to True.
As a source of data, LabelGadget and its subclasses support the
following 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.
COMPOUND_TEXT [Toc] [Back]
The widget transfers XmNlabelString as type COMPOUND_TEXT.
This target is supported only when XmNlabelType is XmSTRING.
PIXMAP The widget transfers XmNlabelPixmap as type DRAWABLE. This
target is supported only when XmNlabelType is XmPIXMAP.
STRING The widget transfers XmNlabelString as type STRING. This
target is supported only when XmNlabelType is XmSTRING.
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
XmNlabelString as type COMPOUND_TEXT. This target is
supported only when XmNlabelType is XmSTRING.
_MOTIF_CLIPBOARD_TARGETS
The widget transfers, as type ATOM, a list of the targets it
supports for the CLIPBOARD selection. When XmNlabelType is
XmSTRING, these include the following targets:
+ _MOTIF_COMPOUND_STRING
+ COMPOUND_TEXT
+ 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, the targets include PIXMAP.
_MOTIF_COMPOUND_STRING
The widget transfers XmNlabelString as a compound string in
Byte Stream format. This target is supported only when
XmNlabelType is XmSTRING.
_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
- 2 - Formatted: January 24, 2005
XmLabelGadget(library call) XmLabelGadget(library call)
in a drag-and-drop transfer. When XmNlabelType is XmSTRING,
these include _MOTIF_COMPOUND_STRING, COMPOUND_TEXT, the
encoding of the locale, STRING, TEXT, BACKGROUND, and
FOREGROUND. When XmNlabelType is XmPIXMAP, these include
PIXMAP, BACKGROUND, and FOREGROUND.
As a source of data, LabelGadget also supports the following standard
Motif targets:
BACKGROUND [Toc] [Back]
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 [Toc] [Back]
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
COLORMAP.
FOREGROUND [Toc] [Back]
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, these also include
_MOTIF_COMPOUND_STRING, COMPOUND_TEXT, the encoding of the
locale, STRING, and TEXT. When XmNlabelType is XmPIXMAP,
these also include PIXMAP.
TIMESTAMP The widget transfers the timestamp used to acquire the
selection 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
target for the Motif Segment Encoding Registry. Widgets and
- 3 - Formatted: January 24, 2005
XmLabelGadget(library call) XmLabelGadget(library call)
applications can use this Registry to register text encoding
formats for specified render table tags. Applications
access this Registry by calling XmRegisterSegmentEncoding
and XmMapSegmentEncoding.
Classes [Toc] [Back]
LabelGadget inherits behavior, resources, and traits from Object,
RectObj and XmGadget.
The class pointer is xmLabelGadgetClass.
The class name is XmLabelGadget.
New Resources [Toc] [Back]
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).

XmNaccelerator [Toc] [Back]
Sets the accelerator on a button widget in a menu, which
activates 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
- 5 - Formatted: January 24, 2005
XmLabelGadget(library call) XmLabelGadget(library call)
single event may be specified and only KeyPress events are
allowed.
Accelerators for buttons are supported only for
PushButtonGadgets and ToggleButtonGadgets in Pulldown and
Popup menus.
XmNacceleratorText [Toc] [Back]
Specifies the text displayed for the accelerator. The text
is displayed adjacent to the label string or pixmap. The
direction of its layout depends on the XmNlayoutDirection
resource of the widget. Accelerator text for buttons is
displayed only for PushButtonGadgets and ToggleButtonGadgets
in Pulldown and Popup Menus.
XmNalignment [Toc] [Back]
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
gadget. 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
vertically 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
gadget. For a pixmap, its right side is vertically
aligned with the right edge of the gadget.
The preceding descriptions for text are correct when
XmNlayoutDirection is XmLEFT_TO_RIGHT. When that resource is
XmRIGHT_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
RowColumn's XmNentryAlignment if the RowColumn's
XmNrowColumnType is XmWORK_AREA or if the gadget is a
subclass of XmLabelGadget. Otherwise, the default is
XmALIGNMENT_CENTER.
XmNfontList [Toc] [Back]
Specifies the font of the text used in the gadget.
XmNfontList is obsolete and exists for compatibility with
- 6 - Formatted: January 24, 2005
XmLabelGadget(library call) XmLabelGadget(library call)
previous 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
ancestor 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 implementation dependent. Refer to
XmFontList(3) for more information on the creation and
structure of a font list.
XmNlabelInsensitivePixmap [Toc] [Back]
Specifies a pixmap used as the button face if XmNlabelType
is XmPIXMAP and the button is insensitive. The default
value, XmUNSPECIFIED_PIXMAP, displays an empty label.
XmNlabelPixmap [Toc] [Back]
Specifies the pixmap when XmNlabelType is XmPIXMAP. The
default value, XmUNSPECIFIED_PIXMAP, displays an empty
label.
XmNlabelString [Toc] [Back]
Specifies the compound string when XmNlabelType is XmSTRING.
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 [Toc] [Back]
Specifies the label type.
XmSTRING Text displays XmNlabelString
XmPIXMAP Icon data in pixmap displays XmNlabelPixmap or
XmNlabelInsensitivePixmap
XmNmarginBottom [Toc] [Back]
Specifies the amount of spacing between the bottom of the
label text and the top of the bottom margin specified by
XmNmarginHeight. This may be modified by LabelGadget's
subclasses. For example, CascadeButtonGadget may increase
this field to make room for the cascade pixmap.
XmNmarginHeight [Toc] [Back]
Specifies an equal amount of spacing above the margin
defined by XmNmarginTop and below the margin defined by
XmNmarginBottom. 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
- 7 - Formatted: January 24, 2005
XmLabelGadget(library call) XmLabelGadget(library call)
amount of spacing between the bottom edge of the margin
specified by XmNmarginBottom and the top edge of the bottom
shadow.
XmNmarginLeft [Toc] [Back]
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
actually applies to the left or right side of the label
depends on the value of XmNlayoutDirection.
XmNmarginRight [Toc] [Back]
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 depends on the value of XmNlayoutDirection.
XmNmarginTop [Toc] [Back]
Specifies the amount of spacing between the top of the label
text and the bottom of the top margin specified by
XmNmarginHeight. This may be modified by LabelGadget's
subclasses. For example, CascadeButtonGadget may increase
this field to make room for the cascade pixmap.
XmNmarginWidth [Toc] [Back]
Specifies an equal amount of spacing to the left of the
margin 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 specified by XmNmarginRight and the left edge of the
right shadow.
XmNmnemonic [Toc] [Back]
Provides the user with an alternate means of activating a
button. A button in a MenuBar, a Popup menu pane, or a
Pulldown 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
XmNmnemonicCharSet is underlined when the button is
displayed.
- 8 - Formatted: January 24, 2005
XmLabelGadget(library call) XmLabelGadget(library call)
When a mnemonic has been specified, the user activates the
button by pressing the mnemonic key while the button is
visible. 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 activate the button by pressing either the shifted
or the unshifted mnemonic key.
XmNmnemonicCharSet [Toc] [Back]
Specifies the character set of the mnemonic for the label.
The default is XmFONTLIST_DEFAULT_TAG.
XmNrecomputeSize [Toc] [Back]
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 [Toc] [Back]
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
XmQTspecifyRenderTable 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 [Toc] [Back]
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
obsoleted by XmNlayoutDirection, but is kept here for
backward compatibility.
Inherited Resources [Toc] [Back]
LabelGadget inherits behavior and resources from the superclasses
described in the following tables. For a complete description of each
resource, refer to the reference page for that superclass.

Behavior [Toc] [Back]
XmLabelGadget includes behavior from XmGadget. Additional
XmLabelGadget behavior is described in the following list:
<Btn2Down>:
Drags the contents of a LabelGadget, identified when
BTransfer 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,
restores keyboard focus to the widget that had the focus
before the menu was entered.
- 11 - Formatted: January 24, 2005
XmLabelGadget(library call) XmLabelGadget(library call)
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,
restores keyboard focus to the widget that had the focus
before the MenuBar was entered. In other Pulldown
MenuPanes, unposts 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
traversable 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 upper, leftmost corner, this action wraps to the tearoff
control, 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 XmLEFT_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
current 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
CascadeButton and is in the bottom, leftmost corner of a
Popup or Pulldown MenuPane, this action wraps to the tearoff
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
current 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
CascadeButton and is in the bottom, rightmost corner of a
Popup or Pulldown MenuPane, this action wraps to the tearoff
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 XmRIGHT_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.

When the current menu item is in a MenuPane, then this
