<p> Special elements are:
<center><table cellpadding="4" cellspacing="2" border="0">
<tr bgcolor="#a2c511"> <th valign="top">Special tags <th valign="top">Notes
<tr bgcolor="#d0d0d0"> <td valign="top"><tt>&lt;img&gt;</tt>
<td valign="top">An image. The image name for the mime source factory is
given in the source attribute, for example
<tt>&lt;img src="qt.xpm"&gt;</tt> The image tag also understands the
attributes <tt>width</tt> and <tt>height</tt> that determine the size
of the image. If the pixmap does not fit the specified
size it will be scaled automatically (by using
<a href="qimage.html#smoothScale">QImage::smoothScale</a>()).
<br>
The <tt>align</tt> attribute determines where the image is
placed. By default, an image is placed inline just like a
normal character. Specify <tt>left</tt> or <tt>right</tt> to place the
image at the respective side.
<tr bgcolor="#f0f0f0"> <td valign="top"><tt>&lt;hr&gt;</tt>
<td valign="top">A horizonal line.
<tr bgcolor="#d0d0d0"> <td valign="top"><tt>&lt;br&gt;</tt>
<td valign="top">A line break.
<tr bgcolor="#f0f0f0"> <td valign="top"><tt>&lt;nobr&gt;...&lt;/nobr&gt;</tt>
<td valign="top">No break. Prevents word wrap.
</table></center>
<p> 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.
<p> <center><table cellpadding="4" cellspacing="2" border="0">
<tr bgcolor="#a2c511"> <th valign="top">Table tags <th valign="top">Notes
<tr bgcolor="#d0d0d0"> <td valign="top"><tt>&lt;table&gt;...&lt;/table&gt;</tt>
<td valign="top">A table. Tables support the following attributes:
<ul>
<li> <tt>bgcolor</tt> -- The background color.
<li> <tt>width</tt> -- The table width. This is either an absolute
pixel width or a relative percentage of the table's
width, for example <tt>width=80%</tt>.
<li> <tt>border</tt> -- The width of the table border. The default is
0 (= no border).
<li> <tt>cellspacing</tt> -- Additional space around the table cells.
The default is 2.
<li> <tt>cellpadding</tt> -- Additional space around the contents of
table cells. The default is 1.
</ul>
<tr bgcolor="#f0f0f0"> <td valign="top"><tt>&lt;tr&gt;...&lt;/tr&gt;</tt>
<td valign="top">A table row. This is only valid within a <tt>table</tt>. Rows
support the following attribute:
<ul>
<li> <tt>bgcolor</tt> -- The background color.
</ul>
<tr bgcolor="#d0d0d0"> <td valign="top"><tt>&lt;th&gt;...&lt;/th&gt;</tt>
<td valign="top">A table header cell. Similar to <tt>td</tt>, but defaults to
center alignment and a bold font.
<tr bgcolor="#f0f0f0"> <td valign="top"><tt>&lt;td&gt;...&lt;/td&gt;</tt>
<td valign="top">A table data cell. This is only valid within a <tt>tr</tt>.
Cells support the following attributes:
<ul>
<li> <tt>bgcolor</tt> -- The background color.
<li> <tt>width</tt> -- The cell width. This is either an absolute
pixel width or a relative percentage of table's width,
for example <tt>width=50%</tt>.
<li> <tt>colspan</tt> -- Specifies how many columns this cell spans.
The default is 1.
<li> <tt>rowspan</tt> -- Specifies how many rows this cell spans. The
default is 1.
<li> <tt>align</tt> -- Alignment; possible values are <tt>left</tt>, <tt>right</tt>, and <tt>center</tt>. The default is left.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QStyleSheet"></a>QStyleSheet::QStyleSheet ( <a href="qobject.html">QObject</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )
</h3>
Creates a style sheet called <em>name</em>, with parent <em>parent</em>. Like
any <a href="qobject.html">QObject</a> it will be deleted when its parent is destroyed (if
the child still exists).
<p> By default the style sheet has the tag definitions defined above.

<h3 class=fn><a name="~QStyleSheet"></a>QStyleSheet::~QStyleSheet ()<tt> [virtual]</tt>
</h3>
Destroys the style sheet. All styles inserted into the style sheet
will be deleted.

<h3 class=fn><a href="qstring.html">QString</a> <a name="convertFromPlainText"></a>QStyleSheet::convertFromPlainText ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;plain, <a href="qstylesheetitem.html#WhiteSpaceMode-enum">QStyleSheetItem::WhiteSpaceMode</a>&nbsp;mode = QStyleSheetItem::WhiteSpacePre )<tt> [static]</tt>
</h3>  Auxiliary function. Converts the plain text string <em>plain</em> to a
rich text formatted paragraph while preserving most of its look.
<p> <em>mode</em> defines the whitespace mode. Possible values are <a href="qstylesheetitem.html#WhiteSpaceMode-enum">QStyleSheetItem::WhiteSpacePre</a> (no wrapping, all whitespaces
preserved) and <a href="qstylesheetitem.html#WhiteSpaceMode-enum">QStyleSheetItem::WhiteSpaceNormal</a> (wrapping,
simplified whitespaces).
<p> <p>See also <a href="#escape">escape</a>().

<h3 class=fn><a href="qstylesheet.html">QStyleSheet</a>&nbsp;* <a name="defaultSheet"></a>QStyleSheet::defaultSheet ()<tt> [static]</tt>
</h3>
Returns the application-wide default style sheet. This style sheet
is used by rich text rendering classes such as <a href="qsimplerichtext.html">QSimpleRichText</a>,
<a href="qwhatsthis.html">QWhatsThis</a> and <a href="qmessagebox.html">QMessageBox</a> 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, <a href="qtextedit.html">QTextEdit</a>
and <a href="qtextbrowser.html">QTextBrowser</a>.
<p> <p>See also <a href="#setDefaultSheet">setDefaultSheet</a>().

<h3 class=fn>void <a name="error"></a>QStyleSheet::error ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;msg ) const<tt> [virtual]</tt>
</h3>

<p> This virtual function is called when an error occurs when
processing rich text. Reimplement it if you need to catch error
messages.
<p> 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.
<p> <em>msg</em> is the error message.

<h3 class=fn><a href="qstring.html">QString</a> <a name="escape"></a>QStyleSheet::escape ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;plain )<tt> [static]</tt>
</h3>
Auxiliary function. Converts the plain text string <em>plain</em> to a
rich text formatted string with any HTML meta-characters escaped.
<p> <p>See also <a href="#convertFromPlainText">convertFromPlainText</a>().

<h3 class=fn><a href="qstylesheetitem.html">QStyleSheetItem</a>&nbsp;* <a name="item"></a>QStyleSheet::item ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;name )
</h3>
Returns the style called <em>name</em> or 0 if there is no such style.

<h3 class=fn>const&nbsp;<a href="qstylesheetitem.html">QStyleSheetItem</a>&nbsp;* <a name="item-2"></a>QStyleSheet::item ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;name ) const
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Returns the style called <em>name</em> or 0 if there is no such style
(const version)

<h3 class=fn>bool <a name="mightBeRichText"></a>QStyleSheet::mightBeRichText ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;text )<tt> [static]</tt>
</h3>
Returns TRUE if the string <em>text</em> is likely to be rich text;
otherwise returns FALSE.
<p> 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.

<h3 class=fn>void <a name="scaleFont"></a>QStyleSheet::scaleFont ( <a href="qfont.html">QFont</a>&nbsp;&amp;&nbsp;font, int&nbsp;logicalSize ) const<tt> [virtual]</tt>
</h3>
Scales the font <em>font</em> to the appropriate physical point size
corresponding to the logical font size <em>logicalSize</em>.
<p> When calling this function, <em>font</em> has a point size corresponding
to the logical font size 3.
<p> Logical font sizes range from 1 to 7, with 1 being the smallest.
<p> <p>See also <a href="qstylesheetitem.html#logicalFontSize">QStyleSheetItem::logicalFontSize</a>(), <a href="qstylesheetitem.html#logicalFontSizeStep">QStyleSheetItem::logicalFontSizeStep</a>() and <a href="qfont.html#setPointSize">QFont::setPointSize</a>().

<h3 class=fn>void <a name="setDefaultSheet"></a>QStyleSheet::setDefaultSheet ( <a href="qstylesheet.html">QStyleSheet</a>&nbsp;*&nbsp;sheet )<tt> [static]</tt>
</h3>
Sets the application-wide default style sheet to <em>sheet</em>,
deleting any style sheet previously set. The ownership is
transferred to QStyleSheet.
<p> <p>See also <a href="#defaultSheet">defaultSheet</a>().

<h3 class=fn>QTextCustomItem * <a name="tag"></a>QStyleSheet::tag ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;name, const&nbsp;<a href="qmap.html">QMap</a>&lt;QString,&nbsp;QString&gt;&nbsp;&amp;&nbsp;attr, const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;context, const&nbsp;<a href="qmimesourcefactory.html">QMimeSourceFactory</a>&nbsp;&amp;&nbsp;factory, bool&nbsp;emptyTag, QTextDocument&nbsp;*&nbsp;doc ) const<tt> [virtual]</tt>
</h3>
<p><b>This function is under development and is subject to change.</b>
<p> Generates an internal object for the tag called <em>name</em>, given the
attributes <em>attr</em>, and using additional information provided by
the mime source factory <em>factory</em>.
<p> <em>context</em> 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.
<a href="qsimplerichtext.html">QSimpleRichText</a> always uses the default mime source factory (see
<a href="qmimesourcefactory.html#defaultFactory">QMimeSourceFactory::defaultFactory</a>()) to resolve these
references. The context will then be used to calculate the
absolute path. See <a href="qmimesourcefactory.html#makeAbsolute">QMimeSourceFactory::makeAbsolute</a>() for details.
<p> <em>emptyTag</em> and <em>doc</em> are for internal use only.
<p> This function should not be used in application code.
