+.SH DESCRIPTION
+The QStyleSheet class is a collection of styles for rich text rendering and a generator of tags.
+.PP
+By creating QStyleSheetItem objects for a style sheet you build a definition of a set of tags. This definition will be used by the internal rich text rendering system to parse and display text documents to which the style sheet applies. Rich text is normally visualized in a QTextEdit or a QTextBrowser. However, QLabel, QWhatsThis and QMessageBox also support it, and other classes are likely to follow. With QSimpleRichText it is possible to use the rich text renderer for custom widgets as well.
+.PP
+The default QStyleSheet object has the following style bindings, sorted by structuring bindings, anchors, character style bindings (i.e. inline styles), special elements such as horizontal lines or images, and other tags. In addition, rich text supports simple HTML tables.
+.PP
+The structuring tags are <center>.nf
+.TS
+l - l. Structuring tags Notes A Qt rich text document. It understands the following attributes:
+.TP
+	A top-level heading.
+	A sublevel heading.
+	A sub-sublevel heading.
+	Headings of lesser importance.
+	A left-aligned paragraph. Adjust the alignment with the
+	A centered paragraph.
+	An indented paragraph that is useful for quotes.
+	An unordered list. You can also pass a type argument to
+define the bullet style. The default is
+	An ordered list. You can also pass a type argument to
+define the enumeration label style. The default is
+	A list item. This tag can be used only within the context
+of
+	A list of definitions, consisting of terms and descriptions.
+	A term in a list of definitions. This tag can be used only
+in the context of

+used only in the context of

+The default character style bindings are <center>.nf

+l - l. Style tags Notes Emphasized. By default this is the same as Strong. By default this is the same as Italic font style. Bold font style. Underlined font style. Strike out font style. A larger font size. A smaller font size. Subscripted text Superscripted text Indicates code. By default this is the same as Typewriter font style. Customizes the font size, family and text color. The tag understands the following attributes:

+In addition, rich text supports simple HTML tables. A table consists of one or more rows each of which contains one or more cells. Cells are either data cells or header cells, depending on their content. Cells which span rows and columns are supported.

+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QStyleSheet::QStyleSheet ( QObject * parent = 0, const char * name = 0 )"
+Creates a style sheet called \fIname\fR, with parent \fIparent\fR. Like any QObject it will be deleted when its parent is destroyed (if the child still exists).
+.PP
+By default the style sheet has the tag definitions defined above.
+.SH "QStyleSheet::~QStyleSheet ()\fC [virtual]\fR"
+Destroys the style sheet. All styles inserted into the style sheet will be deleted.
+.SH "QString QStyleSheet::convertFromPlainText ( const QString & plain, QStyleSheetItem::WhiteSpaceMode mode = QStyleSheetItem::WhiteSpacePre )\fC [static]\fR"
+Auxiliary function. Converts the plain text string \fIplain\fR to a rich text formatted paragraph while preserving most of its look.
+.PP
+\fImode\fR defines the whitespace mode. Possible values are QStyleSheetItem::WhiteSpacePre (no wrapping, all whitespaces preserved) and QStyleSheetItem::WhiteSpaceNormal (wrapping, simplified whitespaces).
+.PP
+See also escape().
+.PP
+Examples:
+.)l action/application.cpp, application/application.cpp, and mdi/application.cpp.
+.SH "QStyleSheet * QStyleSheet::defaultSheet ()\fC [static]\fR"
+Returns the application-wide default style sheet. This style sheet is used by rich text rendering classes such as QSimpleRichText, QWhatsThis and QMessageBox to define the rendering style and available tags within rich text documents. It also serves as the initial style sheet for the more complex render widgets, QTextEdit and QTextBrowser.
+.PP
+See also setDefaultSheet().
+.SH "void QStyleSheet::error ( const QString & msg ) const\fC [virtual]\fR"
+This virtual function is called when an error occurs when processing rich text. Reimplement it if you need to catch error messages.
+.PP
+Errors might occur if some rich text strings contain tags that are not understood by the stylesheet, if some tags are nested incorrectly, or if tags are not closed properly.
+.PP
+\fImsg\fR is the error message.
+.SH "QString QStyleSheet::escape ( const QString & plain )\fC [static]\fR"
+Auxiliary function. Converts the plain text string \fIplain\fR to a rich text formatted string with any HTML meta-characters escaped.
+.PP
+See also convertFromPlainText().
+.SH "QStyleSheetItem * QStyleSheet::item ( const QString & name )"
+Returns the style called \fIname\fR or 0 if there is no such style.
+.SH "const QStyleSheetItem * QStyleSheet::item ( const QString & name ) const"
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+.PP
+Returns the style called \fIname\fR or 0 if there is no such style (const version)
+.SH "bool QStyleSheet::mightBeRichText ( const QString & text )\fC [static]\fR"
+Returns TRUE if the string \fItext\fR is likely to be rich text; otherwise returns FALSE.
+.PP
+This function uses a fast and therefore simple heuristic. It mainly checks whether there is something that looks like a tag before the first line break. Although the result may be correct for common cases, there is no guarantee.
+.SH "void QStyleSheet::scaleFont ( QFont & font, int logicalSize ) const\fC [virtual]\fR"
+Scales the font \fIfont\fR to the appropriate physical point size corresponding to the logical font size \fIlogicalSize\fR.
+.PP
+When calling this function, \fIfont\fR has a point size corresponding to the logical font size 3.
+.PP
+Logical font sizes range from 1 to 7, with 1 being the smallest.
+.PP
+See also QStyleSheetItem::logicalFontSize(), QStyleSheetItem::logicalFontSizeStep(), and QFont::setPointSize().
+.SH "void QStyleSheet::setDefaultSheet ( QStyleSheet * sheet )\fC [static]\fR"
+Sets the application-wide default style sheet to \fIsheet\fR, deleting any style sheet previously set. The ownership is transferred to QStyleSheet.
+.PP
+See also defaultSheet().
+.SH "QTextCustomItem * QStyleSheet::tag ( const QString & name, const QMap<QString, QString> & attr, const QString & context, const QMimeSourceFactory & factory, bool emptyTag, QTextDocument * doc ) const\fC [virtual]\fR"
+\fBThis function is under development and is subject to change.\fR
+.PP
+Generates an internal object for the tag called \fIname\fR, given the attributes \fIattr\fR, and using additional information provided by the mime source factory \fIfactory\fR.
+.PP
+\fIcontext\fR is the optional context of the document, i.e. the path to look for relative links. This becomes important if the text contains relative references, for example within image tags. QSimpleRichText always uses the default mime source factory (see QMimeSourceFactory::defaultFactory()) to resolve these references. The context will then be used to calculate the absolute path. See QMimeSourceFactory::makeAbsolute() for details.
+.PP
+\fIemptyTag\fR and \fIdoc\fR are for internal use only.
+.PP
+This function should not be used in application code.
