|
|---|
| 62 | The QStyleSheet class is a collection of styles for rich text
|
|---|
| 63 | rendering and a generator of tags.
|
|---|
| 64 | <p>
|
|---|
| 65 |
|
|---|
| 66 | <p> By creating <a href="qstylesheetitem.html">QStyleSheetItem</a> objects for a style sheet you build a
|
|---|
| 67 | definition of a set of tags. This definition will be used by the
|
|---|
| 68 | internal rich text rendering system to parse and display text
|
|---|
| 69 | documents to which the style sheet applies. Rich text is normally
|
|---|
| 70 | visualized in a <a href="qtextedit.html">QTextEdit</a> or a <a href="qtextbrowser.html">QTextBrowser</a>. However, <a href="qlabel.html">QLabel</a>,
|
|---|
| 71 | <a href="qwhatsthis.html">QWhatsThis</a> and <a href="qmessagebox.html">QMessageBox</a> also support it, and other classes are
|
|---|
| 72 | likely to follow. With <a href="qsimplerichtext.html">QSimpleRichText</a> it is possible to use the
|
|---|
| 73 | rich text renderer for custom widgets as well.
|
|---|
| 74 | <p> The default QStyleSheet object has the following style bindings,
|
|---|
| 75 | sorted by structuring bindings, anchors, character style bindings
|
|---|
| 76 | (i.e. inline styles), special elements such as horizontal lines or
|
|---|
| 77 | images, and other tags. In addition, rich text supports simple
|
|---|
| 78 | HTML tables.
|
|---|
| 79 | <p> The structuring tags are

|---|

|
|---|
| 84 | attributes:
|

| 85 | <ul>
|

| 86 | <li> <tt>title</tt> -- The caption of the document. This attribute is
|

| 87 | easily accessible with <a href="qtextedit.html#documentTitle">QTextEdit::documentTitle</a>().
|
|---|
| 88 | <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

| 89 | page of its own. Another style is <tt>detail</tt>, which can be
|
|---|
| 90 | used to explain certain expressions in more detail in a
|
|---|
| 91 | few sentences. For <tt>detail</tt>, <a href="qtextbrowser.html">QTextBrowser</a> will then keep
|
|---|
| 92 | the current page and display the new document in a small
|
|---|
| 93 | popup similar to <a href="qwhatsthis.html">QWhatsThis</a>. Note that links will not work
|

|

|
|---|
| 96 | <li> <tt>background</tt> -- The background pixmap, for example <tt>background="granite.xpm"</tt>. The pixmap name will be resolved

|
|---|
| 275 | </h3>
|
|---|
| 276 | Creates a style sheet called <em>name</em>, with parent <em>parent</em>. Like
|
|---|
| 277 | any <a href="qobject.html">QObject</a> it will be deleted when its parent is destroyed (if
|
|---|
| 278 | the child still exists).
|
|---|
| 279 | <p> By default the style sheet has the tag definitions defined above.

|
|---|
| 287 | </h3> Auxiliary function. Converts the plain text string <em>plain</em> to a
|
|---|
| 288 | rich text formatted paragraph while preserving most of its look.
|
|---|
| 289 | <p> <em>mode</em> defines the whitespace mode. Possible values are <a href="qstylesheetitem.html#WhiteSpaceMode-enum">QStyleSheetItem::WhiteSpacePre</a> (no wrapping, all whitespaces
|
|---|
| 290 | preserved) and <a href="qstylesheetitem.html#WhiteSpaceMode-enum">QStyleSheetItem::WhiteSpaceNormal</a> (wrapping,

|

| 297 | Returns the application-wide default style sheet. This style sheet
|
|---|
| 298 | is used by rich text rendering classes such as <a href="qsimplerichtext.html">QSimpleRichText</a>,
|
|---|
| 299 | <a href="qwhatsthis.html">QWhatsThis</a> and <a href="qmessagebox.html">QMessageBox</a> to define the rendering style and
|
|---|
| 300 | available tags within rich text documents. It also serves as the
|

| 301 | initial style sheet for the more complex render widgets, <a href="qtextedit.html">QTextEdit</a>

|
|---|
| 306 | </h3>
|
|---|
| 307 |
|
|---|
| 308 | <p> This virtual function is called when an error occurs when
|
|---|
| 309 | processing rich text. Reimplement it if you need to catch error
|
|---|
| 310 | messages.
|
|---|
| 311 | <p> Errors might occur if some rich text strings contain tags that are
|
|---|
| 312 | not understood by the stylesheet, if some tags are nested
|
|---|
| 313 | incorrectly, or if tags are not closed properly.
|
|---|
| 314 | <p> <em>msg</em> is the error message.
|
|---|

| 316 | <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>
|
|---|
| 317 | </h3>
|
|---|
| 318 | Auxiliary function. Converts the plain text string <em>plain</em> to a
|
|---|
| 319 | rich text formatted string with any HTML meta-characters escaped.
|
|---|
| 320 | <p> <p>See also <a href="#convertFromPlainText">convertFromPlainText</a>().

|
|---|
| 325 |
|
|---|
| 326 | <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
|
|---|
| 327 | </h3>
|
|---|
| 328 | This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|---|
| 329 | <p> Returns the style called <em>name</em> or 0 if there is no such style
|
|---|
| 330 | (const version)

|
|---|
| 333 | </h3>
|
|---|
| 334 | Returns TRUE if the string <em>text</em> is likely to be rich text;
|
|---|
| 335 | otherwise returns FALSE.
|
|---|
| 336 | <p> This function uses a fast and therefore simple heuristic. It
|
|---|
| 337 | mainly checks whether there is something that looks like a tag
|
|---|
| 338 | before the first line break. Although the result may be correct
|
|---|
| 339 | for common cases, there is no guarantee.

|

| 343 | Scales the font <em>font</em> to the appropriate physical point size
|
|---|
| 344 | corresponding to the logical font size <em>logicalSize</em>.
|
|---|
| 345 | <p> When calling this function, <em>font</em> has a point size corresponding
|
|---|
| 346 | to the logical font size 3.
|
|---|
| 347 | <p> Logical font sizes range from 1 to 7, with 1 being the smallest.

|
|---|
| 352 | Sets the application-wide default style sheet to <em>sheet</em>,
|
|---|
| 353 | deleting any style sheet previously set. The ownership is
|
|---|
| 354 | transferred to QStyleSheet.

|
|---|
| 358 | </h3>
|
|---|
| 359 | <p><b>This function is under development and is subject to change.</b>
|
|---|
| 360 | <p> Generates an internal object for the tag called <em>name</em>, given the
|
|---|
| 361 | attributes <em>attr</em>, and using additional information provided by
|
|---|
| 362 | the mime source factory <em>factory</em>.
|
|---|
| 363 | <p> <em>context</em> is the optional context of the document, i.e. the path
|
|---|
| 364 | to look for relative links. This becomes important if the text
|
|---|
| 365 | contains relative references, for example within image tags.
|
|---|
| 366 | <a href="qsimplerichtext.html">QSimpleRichText</a> always uses the default mime source factory (see
|
|---|
| 367 | <a href="qmimesourcefactory.html#defaultFactory">QMimeSourceFactory::defaultFactory</a>()) to resolve these
|
|---|
| 368 | references. The context will then be used to calculate the
|
|---|
| 369 | absolute path. See <a href="qmimesourcefactory.html#makeAbsolute">QMimeSourceFactory::makeAbsolute</a>() for details.
|
|---|
| 370 | <p> <em>emptyTag</em> and <em>doc</em> are for internal use only.
|
|---|
| 371 | <p> This function should not be used in application code.
