Name

XbaeCaption - The Bellcore Application Environment (BAE) XbaeCaption widget class.

Synopsis

#include <Xbae/Caption.h>

Description

XbaeCaption is a simple manager used to associate a label with its single child. The label may be either an XmString or a Pixmap and can be displayed in any one of twelve positions around the edge of the child. XbaeCaption performs geometry management so that its size always matches its child's size plus the size of the label and label offset. By using XbaeCaption with an XmFrame child, groups of related widgets can be labeled in a visually appealing manner. XbaeCaption is also useful for associating labels with individual XmTextFields.

Classes

XbaeCaption inherits behavior and resources from the Core, Composite, Constraint and XmManager widget classes.
The class pointer is xbaeCaptionWidgetClass.
The class name is XbaeCaption.

New Resources

The following table lists the new resources defined by XbaeCaption. The codes in the Access column indicate whether the given resource can be set at creation time (C), or set by using XtSetValues (S), or retrieved by using XtGetValues (G).

XmNlabelTextAlignment    XmCAlignment    Alignment    XmALIGNMENT_CENTER    CSG
XmNlabelType    XmCLabelType    LabelType    XmString    CSG

XmNfontList
Specifies the font of the text used in the caption label. If this value is NULL at initialization, it 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 appropriate default font list of the ancestor widget XmNdefaultFontList for VendorShell and XmMenuShell, XmNlabelFontList or XmNbuttonFontList for XmBulletinBoard. Refer to XmFontList(3X) for more information on the creation and structure of a font list. This resource is copied.
XmNlabelAlignment
Specifies the alignment of the caption label along the side of the caption child. Must be one of the enumerated XbaeLabelAlignment types: XbaeAlignmentTopOrLeft, XbaeAlignmentCenter, XbaeAlignmentBottomOrRight.
XmNlabelOffset
Specifies the offset, in pixels, of the caption label from the caption child. If the offset is negative, then the caption label will overlap the caption child by that many pixels.
XmNlabelPixmap
Specifies the caption label pixmap when XmNlabelType is XmPIXMAP.
XmNlabelPosition
Specifies on which side of the caption child the caption label should be placed. Must be one of the enumerated XbaeLabelPosition types: XbaePositionLeft, XbaePositionRight, XbaePositionTop, XbaePositionBottom.
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(3X) for more information on the creation and structure of compound strings.
XmNlabelTextAlignment
Specifies the text alignment for the caption label. This resource is only useful for multi line caption labels. Valid values are: XmALIGNMENT_BEGINNING left alignment causes the left sides of the lines of text to be vertically aligned. XmALIGNMENT_CENTER center alignment causes the centers of the lines of text to be vertically aligned. XmALIGNMENT_END right alignment causes the right sides of the lines of text to be vertically aligned.
XmNlabelType
Specifies the caption label type. Valid values are: XmSTRING - the caption label will display the XmNlabelString. XmPIXMAP - the caption label will display the XmNlabelPixmap.

Inherited Resources

Translations

XbaeCaption inherits translations from XmManager.

Type Converters

In addition to the standard type converters registered by Xt and Motif, XbaeCaption registers the following additional type converters:

CvtStringToLabelAlignment()
Converts a String to the enumerated XbaeLabelAlignment type. The Strings TopOrLeft, Top and Left are converted to XbaeAlignmentTopOrLeft. The String Center is converted to XbaeAlignmentCenter. The Strings BottomOrRight, Bottom and Right are converted to XbaeAlignmentBottomOrRight. This converter allows the XmNlabelAlignment resource to be specified in a resource file. The converter is case insensitive.
CvtStringToLabelPosition()
Converts a String to the enumerated XbaeLabelPosition type. The String Left is converted to XbaePositionLeft. The String Right is converted to XbaePositionRight. The String Top is converted to XbaePositionTop. The String Bottom is converted to XbaePositionBottom. This converter allows the XmNlabelPosition resource to be specified in a resource file. The converter is case insensitive.

Public Functions
