.SH DESCRIPTION
The QStyleSheetItem class provides an encapsulation of a set of text styles.
.PP
A style sheet item consists of a name and a set of attributes that specifiy its font, color, etc. When used in a style sheet (see styleSheet()), items define the name() of a rich text tag and the display property changes associated with it.
.PP
The display mode attribute indicates whether the item is a block, an inline element or a list element; see setDisplayMode(). The treatment of whitespace is controlled by the white space mode; see setWhiteSpaceMode(). An item's margins are set with setMargin(), In the case of list items, the list style is set with setListStyle(). An item may be a hypertext link anchor; see setAnchor(). Other attributes are set with setAlignment(), setVerticalAlignment(), setFontFamily(), setFontSize(), setFontWeight(), setFontItalic(), setFontUnderline(), setFontStrikeOut and setColor().
.PP
See also Text Related Classes.
.SS "Member Type Documentation"
.SH "QStyleSheetItem::DisplayMode"
This enum type defines the way adjacent elements are displayed.
.TP
\fCQStyleSheetItem::DisplayBlock\fR - elements are displayed as a rectangular block (e.g. \fC<p>...</p>\fR).
.TP
\fCQStyleSheetItem::DisplayInline\fR - elements are displayed in a horizontally flowing sequence (e.g. \fC<em>...</em>\fR).
.TP
\fCQStyleSheetItem::DisplayListItem\fR - elements are displayed in a vertical sequence (e.g. \fC<li>...</li>\fR).
.TP
\fCQStyleSheetItem::DisplayNone\fR - elements are not displayed at all.
.SH "QStyleSheetItem::ListStyle"
This enum type defines how the items in a list are prefixed when displayed.
.TP
\fCQStyleSheetItem::ListDisc\fR - a filled circle (i.e. a bullet)
.TP
\fCQStyleSheetItem::ListCircle\fR - an unfilled circle
.TP
\fCQStyleSheetItem::ListSquare\fR - a filled square
.TP
\fCQStyleSheetItem::ListDecimal\fR - an integer in base 10: \fI1\fR, \fI2\fR, \fI3\fR, ...
.TP
\fCQStyleSheetItem::ListLowerAlpha\fR - a lowercase letter: \fIa\fR, \fIb\fR, \fIc\fR, ...
.TP
\fCQStyleSheetItem::ListUpperAlpha\fR - an uppercase letter: \fIA\fR, \fIB\fR, \fIC\fR, ...
.SH "QStyleSheetItem::Margin"

.SH "QStyleSheetItem::WhiteSpaceMode"
This enum defines the ways in which QStyleSheet can treat whitespace.

\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.

.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 a space-separated list of names of styles that may contain elements of this style. If nothing has been set, contexts() returns an empty string, which indicates that this style can be nested everywhere.

.PP
See also setFontItalic() and fontItalic().
.SH "bool QStyleSheetItem::definesFontStrikeOut () 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::setNumberOfColumns ( int ncols )"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
Sets the number of columns for this style. Elements in the style are divided into columns.
.PP
This makes sense only if the style uses a block display mode (see QStyleSheetItem::DisplayMode).
.PP
See also numberOfColumns().
.SH "void QStyleSheetItem::setSelfNesting ( bool nesting )"
Sets the self-nesting property for this style to \fInesting\fR.
.PP
In order to support "dirty" HTML, paragraphs \fC<p>\fR and list items \fC<li>\fR are not self-nesting. This means that starting a new paragraph or list item automatically closes the previous one.
.PP
See also selfNesting().
.SH "void QStyleSheetItem::setVerticalAlignment ( VerticalAlignment valign )"
Sets the vertical alignment to \fIvalign\fR. Possible values are VAlignBaseline, VAlignSub or VAlignSuper.
