XmLabel(Xm)


XmLabel -- the Label widget class

Syntax

#include <Xm/Label.h>

Description

Label is an instantiable widget and is also used as a superclass for other button widgets, such as PushButton and ToggleButton. The Label widget does not accept any button or key input, and the help callback is the only callback defined. Label also receives enter and leave events.

Label can contain either text or a pixmap. Label text is a compound string. Refer to the OSF/Motif Programmer's Guide for more information on compound strings. The text can be multilingual, multiline, and/or multifont. When a Label is insensitive, its text is stippled, or the user-supplied insensitive pixmap is displayed.

Label supports both accelerators and mnemonics primarily for use in Label 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 Label widget 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.

Label consists of many margin fields surrounding the text or pixmap. These margin fields are resources that may be set by the user, but Label 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.

Label takes into account XmNshadowThickness in determining its layout but does not draw the shadow. That is, if XmNshadowThickness is greater than 0, Label leaves space for the shadow, but the shadow does not appear.

In a Label XmNtraversalOn and XmNhighlightOnEnter are forced to False inside Popup MenuPanes, Pulldown MenuPanes, and OptionMenus. Otherwise these resources default to False.

Classes

Label inherits behavior and resources from Core and XmPrimitive classes.

The class pointer is xmLabelWidgetClass.

The class name is XmLabel.

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 PushButtons and ToggleButtons in Pulldown and Popup MenuPanes.


XmNacceleratorText
Specifies the text displayed for the accelerator. The text is displayed adjacent to the label string or pixmap. Accelerator text for buttons is displayed only for PushButtons and ToggleButtons in Pulldown and Popup Menus.

XmNalignment
Specifies the label alignment for text or pixmap.

The above descriptions for text are correct when XmNstringDirection is XmSTRING_DIRECTION_L_TO_R. When that resource is XmSTRING_DIRECTION_R_TO_L, 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 widget is a subclass of XmLabel. Otherwise, the default is XmALIGNMENT_CENTER.


XmNfontList
Specifies the font of the text used in the widget. If this value is NULL at initialization, the font list is initialized by looking up the parent hierarchy of the widget 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 subclasses) or XmNlabelFontList of the ancestor widget. If no such ancestor is found, the default is implementation dependent. Refer to XmFontList(Xm) 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 and the button is insensitive. The default value, XmUNSPECIFIED_PIXMAP, displays an empty label.

XmNlabelPixmap
Specifies the pixmap when XmNlabelType is XmPIXMAP. The default value, XmUNSPECIFIED_PIXMAP, displays an empty label.

XmNlabelString
Specifies the compound string when the XmNlabelType is XmSTRING. If this value is NULL, it is initialized by converting the name of the widget to a compound string. Refer to XmString(Xm) for more information on the creation and structure of compound strings.

XmNlabelType
Specifies the label type.

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 Label's subclasses. For example, CascadeButton 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 Label's subclasses. For example, ToggleButton 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 may depend on the value of XmNstringDirection.

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 Label's subclasses. For example, CascadeButton may increase this field to make room for the cascade pixmap. Whether this actually applies to the left or right side of the label may depend on the value of XmNstringDirection.

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 Label's subclasses. For example, CascadeButton 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 MenuPane, or a Pulldown MenuPane 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 CascadeButton 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.

XmNrecomputeSize
Specifies a Boolean value that indicates whether the widget 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 widget. If True, the widget shrinks or expands to exactly fit the label string or pixmap. If False, the widget never attempts to change size on its own.

XmNstringDirection
Specifies the direction in which the string is to be drawn. The following are the values:

The default for this resource is determined at creation time. If no value is specified for this resource and the widget's parent is a manager, the value is inherited from the parent; otherwise, it defaults to XmSTRING_DIRECTION_L_TO_R.

Inherited resources

Label inherits behavior and resources from the following superclasses. For a complete description of each resource, refer to the man page for that superclass.

Translations

XmLabel includes translations from Primitive. The XmLabel translations are listed below. These translations may not directly correspond to a translation table.
   BDrag Press:    ProcessDrag()
   

KHelp: Help()

The translations used by subclasses of XmLabel for menu traversal are listed below. These translations may not directly correspond to a translation table.
   KLeft:          MenuTraverseLeft()
   KRight:         MenuTraverseRight()
   KUp:            MenuTraverseUp()
   KDown:          MenuTraverseDown()
   MAny KCancel:   MenuEscape()

Action routines

The XmLabel action routines are described below:

Help():
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.

MenuEscape():
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 and moves the focus to its CascadeButton.

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.


MenuTraverseDown():
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. When the current menu item is at the MenuPane's bottom edge, then this action wraps to the topmost menu item in the column
to the right, if one exists. When the current menu item is at the bottom, rightmost corner of the MenuPane, then this action wraps to the tear-off control, if present, or to the top, leftmost menu item.

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.

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.
