<div class="descr">
<h2>Detailed Description</h2>
<p>The QTextDocument class holds formatted text that can be viewed and edited using a <a href="qtextedit.html">QTextEdit</a>.</p>
<p>QTextDocument is a container for structured rich text documents, providing support for styled text and various types of document elements, such as lists, tables, frames, and images. They can be created for use in a <a href="qtextedit.html">QTextEdit</a>, or used independently.</p>
<p>Each document element is described by an associated format object. Each format object is treated as a unique object by QTextDocuments, and can be passed to <a href="qtextdocument.html#objectForFormat">objectForFormat</a>() to obtain the document element that it is applied to.</p>
<p>A QTextDocument can be edited programmatically using a <a href="qtextcursor.html">QTextCursor</a>, and its contents can be examined by traversing the document structure. The entire document structure is stored as a hierarchy of document elements beneath the root frame, found with the <a href="qtextdocument.html#rootFrame">rootFrame</a>() function. Alternatively, if you just want to iterate over the textual contents of the document you can use <a href="qtextdocument.html#begin">begin</a>(), <a href="qtextdocument.html#end">end</a>(), and <a href="qtextdocument.html#findBlock">findBlock</a>() to retrieve text blocks that you can examine and iterate over.</p>
<p>The layout of a document is determined by the <a href="qtextdocument.html#documentLayout">documentLayout</a>(); you can create your own <a href="qabstracttextdocumentlayout.html">QAbstractTextDocumentLayout</a> subclass and set it using <a href="qtextdocument.html#setDocumentLayout">setDocumentLayout</a>() if you want to use your own layout logic. The document's title and other meta-information can be obtained by calling the <a href="qtextdocument.html#metaInformation">metaInformation</a>() function. For documents that are exposed to users through the <a href="qtextedit.html">QTextEdit</a> class, the document title is also available via the <a href="qtextedit.html#documentTitle-prop">QTextEdit::documentTitle</a>() function.</p>
<p>The <a href="qtextdocument.html#toPlainText">toPlainText</a>() and <a href="qtextdocument.html#toHtml">toHtml</a>() convenience functions allow you to retrieve the contents of the document as plain text and HTML. The document's text can be searched using the <a href="qtextdocument.html#find">find</a>() functions.</p>
<p>Undo/redo of operations performed on the document can be controlled using the <a href="qtextdocument.html#undoRedoEnabled-prop">setUndoRedoEnabled</a>() function. The undo/redo system can be controlled by an editor widget through the <a href="qtextdocument.html#undo">undo</a>() and <a href="qtextdocument.html#redo">redo</a>() slots; the document also provides <a href="qtextdocument.html#contentsChanged">contentsChanged</a>(), <a href="qtextdocument.html#undoAvailable">undoAvailable</a>(), and <a href="qtextdocument.html#redoAvailable">redoAvailable</a>() signals that inform connected editor widgets about the state of the undo/redo system. The following are the undo/redo operations of a QTextDocument:</p>
<ul>
<li>Insertion or removal of characters. A sequence of insertions or removals within the same text block are regarded as a single undo/redo operation.</li>
<li>Insertion or removal of text blocks. Sequences of insertion or removals in a single operation (e.g., by selecting and then deleting text) are regarded as a single undo/redo operation.</li>
<li>Text character format changes.</li>
<li>Text block format changes.</li>
<li>Text block group format changes.</li>
</ul>

<p>If the text width is set to -1 then the text will not be broken into multiple lines unless it is enforced through an explicit line break or a new paragraph.</p>
<p>The default value is -1.</p>
<p>Setting the text width will also set the page height to -1, causing the document to grow or shrink vertically in a continuous way.

<!-- $$$pageCount[overload1]$$$pageCount -->

<p>Prints the document to the given <i>printer</i>. The <a href="qprinter.html">QPrinter</a> must be set up before being used with this function.</p>
<p>This is only a convenience method to print the whole document to the printer.</p>
<p>If the document is already paginated through a specified height in the <a href="qtextdocument.html#pageSize-prop">pageSize</a>() property it is printed as-is.</p>
<p>If the document is not paginated, like for example a document used in a <a href="qtextedit.html">QTextEdit</a>, then a temporary copy of the document is created and the copy is broken into multiple pages according to the size of the <a href="qprinter.html">QPrinter</a>'s paperRect(). By default a 2 cm margin is set around the document contents. In addition the current page number is printed at the bottom of each page.</p>
<p>Note that <a href="qprinter.html#PrintRange-enum">QPrinter::Selection</a> is not supported as print range with this function since the selection is a property of <a href="qtextcursor.html">QTextCursor</a>. If you have a <a href="qtextedit.html">QTextEdit</a> associated with your <a href="qtextdocument.html">QTextDocument</a> then you can use <a href="qtextedit.html">QTextEdit</a>'s print() function because <a href="qtextedit.html">QTextEdit</a> has access to the user's selection.</p>

<p>The provided <i>cursor</i> is positioned at the end of the location where the edition operation was redone.</p>

<p>Returns data of the specified <i>type</i> from the resource with the given <i>name</i>.</p>
<p>This function is called by the rich text engine to request data that isn't directly stored by <a href="qtextdocument.html">QTextDocument</a>, but still associated with it. For example, images are referenced indirectly by the name attribute of a <a href="qtextimageformat.html">QTextImageFormat</a> object.</p>
<p>Resources are cached internally in the document. If a resource can not be found in the cache, loadResource is called to try to load the resource. loadResource should then use addResource to add the resource to the cache.</p>

<p>Replaces the entire contents of the document with the given HTML-formatted text in the <i>html</i> string.</p>
<p>The HTML formatting is respected as much as possible; for example, "<b>bold</b> text" will produce text where the first word has a font weight that gives it a bold appearance: "<b>bold</b> text".</p>
<p><b>Note:</b> It is the responsibility of the caller to make sure that the text is correctly decoded when a <a href="qstring.html">QString</a> containing HTML is created and passed to setHtml().</p>

<p>Returns a string containing an HTML representation of the document.</p>
<p>The <i>encoding</i> parameter specifies the value for the charset attribute in the html header. For example if 'utf-8' is specified then the beginning of the generated html will look like this:</p>
<pre class="cpp"> <span class="operator"><</span>html<span class="operator">></span><span class="operator"><</span>head<span class="operator">></span><span class="operator"><</span>meta http<span class="operator">-</span>equiv<span class="operator">=</span><span class="string">"Content-Type"</span> content<span class="operator">=</span><span class="string">"text/html; charset=utf-8"</span><span class="operator">></span><span class="operator"><</span><span class="operator">/</span>head<span class="operator">></span><span class="operator"><</span>body<span class="operator">></span><span class="operator">.</span><span class="operator">.</span><span class="operator">.</span></pre>
<p>If no encoding is specified then no such meta information is generated.</p>
<p>If you later on convert the returned html string into a byte array for transmission over a network or when saving to disk you should specify the encoding you're going to use for the conversion to a byte array here.</p>
