.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

.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"
.TP
\fCQStyleSheetItem::MarginLeft\fR - left margin
.TP
\fCQStyleSheetItem::MarginRight\fR - right margin
.TP
\fCQStyleSheetItem::MarginTop\fR - top margin
.TP
\fCQStyleSheetItem::MarginBottom\fR - bottom margin
.TP
\fCQStyleSheetItem::MarginAll\fR - all margins (left, right, top and bottom)
.TP
\fCQStyleSheetItem::MarginVertical\fR - top and bottom margins
.TP
\fCQStyleSheetItem::MarginHorizontal\fR - left and right margins
.TP
\fCQStyleSheetItem::MarginFirstLine\fR - margin (indentation) of the first line of a paragarph (in addition to the MarginLeft of the paragraph)
.SH "QStyleSheetItem::VerticalAlignment"
This enum type defines the way elements are aligned vertically. This is only supported for text elements.
.TP
\fCQStyleSheetItem::VAlignBaseline\fR - align the baseline of the element (or the bottom, if the element doesn't have a baseline) with the baseline of the parent
.TP
\fCQStyleSheetItem::VAlignSub\fR - subscript the element
.TP
\fCQStyleSheetItem::VAlignSuper\fR - superscript the element
.SH "QStyleSheetItem::WhiteSpaceMode"
This enum defines the ways in which QStyleSheet can treat whitespace.
