The QStyleSheet class is a collection of styles for rich text
|
||
|
|
rendering and a generator of tags.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> By creating <a href="qstylesheetitem.html">QStyleSheetItem</a> 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 <a href="qtextedit.html">QTextEdit</a> or a <a href="qtextbrowser.html">QTextBrowser</a>. However, <a href="qlabel.html">QLabel</a>,
|
||
|
|
<a href="qwhatsthis.html">QWhatsThis</a> and <a href="qmessagebox.html">QMessageBox</a> also support it, and other classes are
|
||
|
|
likely to follow. With <a href="qsimplerichtext.html">QSimpleRichText</a> it is possible to use the
|
||
|
|
rich text renderer for custom widgets as well.
|
||
|
|
<p> 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.
|
||
|
|
<p> The structuring tags are

||
|

<td valign="top">A Qt rich text document. It understands the following
|
||
|

attributes:
|
||
|
|
<ul>
|

|
|
<li> <tt>title</tt> -- The caption of the document. This attribute is
|
||
|
|
easily accessible with <a href="qtextedit.html#documentTitle">QTextEdit::documentTitle</a>().
|
||
|
|
<li> <tt>type</tt> -- The type of the document. The default type is <tt>page</tt>. It indicates that the document is displayed in a
|
||
|
|
page of its own. Another style is <tt>detail</tt>, which can be
|
||
|
|
used to explain certain expressions in more detail in a
|
||
|
|
few sentences. For <tt>detail</tt>, <a href="qtextbrowser.html">QTextBrowser</a> will then keep
|
||
|
|
the current page and display the new document in a small
|
||
|
|
popup similar to <a href="qwhatsthis.html">QWhatsThis</a>. Note that links will not work
|
||
|
|
in documents with <tt><qt type="detail">...</qt></tt>.
|
||
|
|
<li> <tt>bgcolor</tt> -- The background color, for example <tt>bgcolor="yellow"</tt> or <tt>bgcolor="#0000FF"</tt>.
|
||
|
|
<li> <tt>background</tt> -- The background pixmap, for example <tt>background="granite.xpm"</tt>. The pixmap name will be resolved
|
||
|
|
by a <a href="qmimesourcefactory.html">QMimeSourceFactory</a>().
|

<li> <tt>text</tt> -- The default text color, for example <tt>text="red"</tt>.

<h3 class=fn><a name="QStyleSheet"></a>QStyleSheet::QStyleSheet ( <a href="qobject.html">QObject</a> * parent = 0, const char * 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> 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).

</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>.

<h3 class=fn>void <a name="error"></a>QStyleSheet::error ( const <a href="qstring.html">QString</a> & 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 <a href="qstring.html">QString</a> & 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> * <a name="item"></a>QStyleSheet::item ( const <a href="qstring.html">QString</a> & name )
|
||
|
|
</h3>
|
||
|
|
Returns the style called <em>name</em> or 0 if there is no such style.
|
||
|
|
|
||
|
|
<h3 class=fn>const <a href="qstylesheetitem.html">QStyleSheetItem</a> * <a name="item-2"></a>QStyleSheet::item ( const <a href="qstring.html">QString</a> & 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 <a href="qstring.html">QString</a> & 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> & font, int 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> * 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.
|
||
|

|
||
|
|
</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.
