.TP
\fCQStyleSheetItem::WhiteSpaceNormal\fR - any sequence of whitespace (including line-breaks) is equivalent to a single space.
.TP
\fCQStyleSheetItem::WhiteSpacePre\fR - whitespace must be output exactly as given in the input.
.TP
\fCQStyleSheetItem::WhiteSpaceNoWrap\fR - multiple spaces are collapsed as with WhiteSpaceNormal, but no automatic line-breaks occur. To break lines manually, use the \fC<br>\fR tag.
.PP
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QStyleSheetItem::QStyleSheetItem ( QStyleSheet * parent, const QString & name )"
Constructs a new style called \fIname\fR for the stylesheet \fIparent\fR.
.PP
All properties in QStyleSheetItem are initially in the "do not change" state, except display mode, which defaults to DisplayInline.
.SH "QStyleSheetItem::QStyleSheetItem ( const QStyleSheetItem & other )"
Copy constructor. Constructs a copy of \fIother\fR that is not bound to any style sheet.
.SH "QStyleSheetItem::~QStyleSheetItem ()"
Destroys the style. Note that QStyleSheetItem objects become owned by QStyleSheet when they are created.
.SH "int QStyleSheetItem::alignment () const"
Returns the alignment of this style. Possible values are AlignAuto, AlignLeft, AlignRight, AlignCenter or AlignJustify.
.PP
See also setAlignment() and Qt::AlignmentFlags.
.SH "bool QStyleSheetItem::allowedInContext ( const QStyleSheetItem * s ) const"
Returns TRUE if this style can be nested into an element of style \fIs\fR; otherwise returns FALSE.
.PP
See also contexts() and setContexts().
.SH "QColor QStyleSheetItem::color () const"
Returns the text color of this style or an invalid color if no color has been set.
.PP
See also setColor() and QColor::isValid().
.SH "QString QStyleSheetItem::contexts () const"

Returns TRUE if the style defines a setting for the strikeOut property of the font; otherwise returns FALSE. A style does not define this until setFontStrikeOut() is called.
.PP
See also setFontStrikeOut() and fontStrikeOut().
.SH "bool QStyleSheetItem::definesFontUnderline () const"
Returns TRUE if the style defines a setting for the underline property of the font; otherwise returns FALSE. A style does not define this until setFontUnderline() is called.

.SH "void QStyleSheetItem::setSelfNesting ( bool nesting )"
Sets the self-nesting property for this style to \fInesting\fR.
