.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(), and line spacing is set with setLineSpacing(). 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() and setColor().
.PP

.SS "Member Type Documentation"
.SH "QStyleSheetItem::DisplayMode"
This enum type defines the way adjacent elements are displayed. The possible values are:
.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. The currently defined values are:
.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 supported for text elements only. The possible values are:
.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
