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
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

LabelGadget and it subclasses, except when used in a menu system,
support dragging of the label contents from the LabelGadget.
However, 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 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
XmNlabelString 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:

+o _MOTIF_COMPOUND_STRING

+o COMPOUND_TEXT

+o UTF8_STRING

+o The encoding of the locale, if XmNlabelString is
fully convertible to the encoding of the locale

+o 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
XmNlabelType 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
COLORMAP.

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
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 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

LabelGadget inherits behavior, resources, and traits from Object,
RectObj 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
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
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 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
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
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
Specifies the font of the text used in the gadget.
XmNfontList is obsolete and exists for compatibility with
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
Specifies a pixmap used as the button face if XmNlabelType
is XmPIXMAP or XmPIXMAP_AND_STRING and the button is
insensitive. The default value, XmUNSPECIFIED_PIXMAP,
displays an empty label.

XmNlabelPixmap
Specifies the pixmap when XmNlabelType is XmPIXMAP or
XmPIXMAP_AND_STRING. The default value,
XmUNSPECIFIED_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
XmNlabelInsensitivePixmap XmPIXMAP_AND_STRING
Icon data in pixmap displays XmNlabelPixmap or
XmNlabelInsensitivePixmap and text displays
XmNlabelString

XmNmarginBottom
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
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
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 actually 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 depends 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
XmNmarginHeight. 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
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
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.

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
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
label 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
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
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

Behavior

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.

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 tear-off 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 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
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 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 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.

<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.
