<h2>Detailed Description</h2>
<p>The Q3TextEdit widget provides a powerful single-page rich text editor.</p>
<a name="introduction-and-concepts"></a>
<h3>Introduction and Concepts</h3>
<p>Q3TextEdit is an advanced WYSIWYG viewer/editor supporting rich text formatting using HTML-style tags. It is optimized to handle large documents and to respond quickly to user input.</p>
<p>Q3TextEdit has four modes of operation:</p>
<table class="generic">
<thead><tr class="qt-style"><th >Mode</th><th >Command</th><th >Notes</th></tr></thead>
<tr valign="top" class="odd"><td >Plain Text Editor</td><td >setTextFormat(<a href="qt.html#TextFormat-enum">Qt::PlainText</a>)</td><td >Set text with <a href="q3textedit.html#text-prop">setText</a>(); <a href="q3textedit.html#text-prop">text</a>() returns plain text. Text attributes (e.g. colors) can be set, but plain text is always returned.</td></tr>
<tr valign="top" class="even"><td >Rich Text Editor</td><td >setTextFormat(<a href="qt.html#TextFormat-enum">Qt::RichText</a>)</td><td >Set text with <a href="q3textedit.html#text-prop">setText</a>(); <a href="q3textedit.html#text-prop">text</a>() returns rich text. Rich text editing is fairly limited. You can't set margins or insert images for example (although you can read and correctly display files that have margins set and that include images). This mode is mostly useful for editing small amounts of rich text.</td></tr>
<tr valign="top" class="odd"><td >Text Viewer</td><td >setReadOnly(true)</td><td >Set text with <a href="q3textedit.html#text-prop">setText</a>() or <a href="q3textedit.html#append">append</a>() (which has no undo history so is faster and uses less memory); <a href="q3textedit.html#text-prop">text</a>() returns plain or rich text depending on the <a href="q3textedit.html#textFormat-prop">textFormat</a>(). This mode can correctly display a large subset of HTML tags.</td></tr>
<tr valign="top" class="even"><td >Log Viewer</td><td >setTextFormat(<a href="qt.html#TextFormat-enum">Qt::LogText</a>)</td><td >Append text using <a href="q3textedit.html#append">append</a>(). The widget is set to be read only and rich text support is disabled although a few HTML tags (for color, bold, italic and underline) may be used. (See <a href="#logtextmode">Qt::LogText mode</a> for details.)</td></tr>
</table>
<p>Q3TextEdit can be used as a syntax highlighting editor when used in conjunction with <a href="qsyntaxhighlighter.html">QSyntaxHighlighter</a>.</p>
<p>We recommend that you always call <a href="q3textedit.html#textFormat-prop">setTextFormat</a>() to set the mode you want to use. If you use <a href="qt.html#TextFormat-enum">Qt::AutoText</a> then <a href="q3textedit.html#text-prop">setText</a>() and <a href="q3textedit.html#append">append</a>() will try to determine whether the text they are given is plain text or rich text. If you use <a href="qt.html#TextFormat-enum">Qt::RichText</a> then <a href="q3textedit.html#text-prop">setText</a>() and <a href="q3textedit.html#append">append</a>() will assume that the text they are given is rich text. <a href="q3textedit.html#insert">insert</a>() simply inserts the text it is given.</p>
<p>Q3TextEdit works on paragraphs and characters. A paragraph is a formatted string which is word-wrapped to fit into the width of the widget. By default when reading plain text, one newline signify a paragraph. A document consists of zero or more paragraphs, indexed from 0. Characters are indexed on a per-paragraph basis, also indexed from 0. The words in the paragraph are aligned in accordance with the paragraph's <a href="q3textedit.html#alignment">alignment</a>(). Paragraphs are separated by hard line breaks. Each character within a paragraph has its own attributes, for example, font and color.</p>
<p>The text edit documentation uses the following concepts:</p>
<ul>
<li><i>current format</i> -- this is the format at the current cursor position, <i>and</i> it is the format of the selected text if any.</li>
<li><i>current paragraph</i> -- the paragraph which contains the cursor.</li>
</ul>
<p>Q3TextEdit can display images (using <a href="q3mimesourcefactory.html">Q3MimeSourceFactory</a>), lists and tables. If the text is too large to view within the text edit's viewport, scroll bars will appear. The text edit can load both plain text and HTML files (a subset of HTML 3.2 and 4). The rendering style and the set of valid tags are defined by a <a href="q3textedit.html#styleSheet">styleSheet</a>(). Custom tags can be created and placed in a custom style sheet. Change the style sheet with <a href="q3textedit.html#setStyleSheet">setStyleSheet</a>(); see <a href="q3stylesheet.html">Q3StyleSheet</a> for details. The images identified by image tags are displayed if they can be interpreted using the text edit's <a href="q3mimesourcefactory.html">Q3MimeSourceFactory</a>; see <a href="q3textedit.html#setMimeSourceFactory">setMimeSourceFactory</a>().</p>
<p>If you want a text browser with more navigation use <a href="qtextbrowser.html">QTextBrowser</a>. If you just need to display a small piece of rich text use <a href="qlabel.html">QLabel</a> or <a href="porting4.html#qsimplerichtext">QSimpleRichText</a>.</p>
<p>If you create a new Q3TextEdit, and want to allow the user to edit rich text, call setTextFormat(<a href="qt.html#TextFormat-enum">Qt::RichText</a>) to ensure that the text is treated as rich text. (Rich text uses HTML tags to set text formatting attributes. See <a href="q3stylesheet.html">Q3StyleSheet</a> for information on the HTML tags that are supported.). If you don't call <a href="q3textedit.html#textFormat-prop">setTextFormat</a>() explicitly the text edit will guess from the text itself whether it is rich text or plain text. This means that if the text looks like HTML or XML it will probably be interpreted as rich text, so you should call setTextFormat(<a href="qt.html#TextFormat-enum">Qt::PlainText</a>) to preserve such text.</p>
<p>Note that we do not intend to add a full-featured web browser widget to Qt (because that would easily double Qt's size and only a few applications would benefit from it). The rich text support in Qt is designed to provide a fast, portable and efficient way to add reasonable online help facilities to applications, and to provide a basis for rich text editors.</p>

<h3>Using Q3TextEdit as a Display Widget</h3>
<p>Q3TextEdit can display a large HTML subset, including tables and images.</p>
<p>The text is set or replaced using <a href="q3textedit.html#text-prop">setText</a>() which deletes any existing text and replaces it with the text passed in the <a href="q3textedit.html#text-prop">setText</a>() call. If you call <a href="q3textedit.html#text-prop">setText</a>() with legacy HTML (with setTextFormat(<a href="qt.html#TextFormat-enum">Qt::RichText</a>) in force), and then call <a href="q3textedit.html#text-prop">text</a>(), the text that is returned may have different markup, but will render the same. Text can be inserted with <a href="q3textedit.html#insert">insert</a>(), <a href="q3textedit.html#paste">paste</a>(), <a href="q3textedit.html#pasteSubType">pasteSubType</a>() and <a href="q3textedit.html#append">append</a>(). Text that is appended does not go into the undo history; this makes <a href="q3textedit.html#append">append</a>() faster and consumes less memory. Text can also be <a href="q3textedit.html#cut">cut</a>(). The entire text is deleted with <a href="q3textedit.html#clear">clear</a>() and the selected text is deleted with <a href="q3textedit.html#removeSelectedText">removeSelectedText</a>(). Selected (marked) text can also be deleted with <a href="q3textedit.html#del">del</a>() (which will delete the character to the right of the cursor if no text is selected).</p>
<p>Loading and saving text is achieved using <a href="q3textedit.html#text-prop">setText</a>() and <a href="q3textedit.html#text-prop">text</a>(), for example:</p>
<pre class="cpp"> <span class="type"><a href="qfile.html">QFile</a></span> file(fileName); <span class="comment">// Read the text from a file</span>
<span class="keyword">if</span> (file<span class="operator">.</span>open(IO_ReadOnly)) {
<span class="type"><a href="qtextstream.html">QTextStream</a></span> stream(<span class="operator">&</span>file);
textEdit<span class="operator">-</span><span class="operator">></span>setText(stream<span class="operator">.</span>read());
}
<span class="type"><a href="qfile.html">QFile</a></span> file(fileName); <span class="comment">// Write the text to a file</span>
<span class="keyword">if</span> (file<span class="operator">.</span>open(IO_WriteOnly)) {
<span class="type"><a href="qtextstream.html">QTextStream</a></span> stream(<span class="operator">&</span>file);
stream <span class="operator"><</span><span class="operator"><</span> textEdit<span class="operator">-</span><span class="operator">></span>text();
textEdit<span class="operator">-</span><span class="operator">></span>setModified(<span class="keyword">false</span>);
}</pre>
<p>By default the text edit wraps words at whitespace to fit within the text edit widget. The <a href="q3textedit.html#wordWrap-prop">setWordWrap</a>() function is used to specify the kind of word wrap you want, or <tt>NoWrap</tt> if you don't want any wrapping. Call <a href="q3textedit.html#wordWrap-prop">setWordWrap</a>() to set a fixed pixel width <tt>FixedPixelWidth</tt>, or character column (e.g. 80 column) <tt>FixedColumnWidth</tt> with the pixels or columns specified with <a href="q3textedit.html#wrapColumnOrWidth-prop">setWrapColumnOrWidth</a>(). If you use word wrap to the widget's width <tt>WidgetWidth</tt>, you can specify whether to break on whitespace or anywhere with <a href="q3textedit.html#wrapPolicy-prop">setWrapPolicy</a>().</p>
<p>The background color is set differently than other widgets, using <a href="q3textedit.html#paper-prop">setPaper</a>(). You specify a brush style which could be a plain color or a complex pixmap.</p>
<p>Hypertext links are automatically underlined; this can be changed with <a href="q3textedit.html#linkUnderline-prop">setLinkUnderline</a>(). The tab stop width is set with <a href="q3textedit.html#tabStopWidth-prop">setTabStopWidth</a>().</p>
<p>The <a href="q3textedit.html#zoomIn">zoomIn</a>() and <a href="q3textedit.html#zoomOut">zoomOut</a>() functions can be used to resize the text by increasing (decreasing for <a href="q3textedit.html#zoomOut">zoomOut</a>()) the point size used. Images are not affected by the zoom functions.</p>
<p>The <a href="q3textedit.html#lines">lines</a>() function returns the number of lines in the text and <a href="q3textedit.html#paragraphs">paragraphs</a>() returns the number of paragraphs. The number of lines within a particular paragraph is returned by <a href="q3textedit.html#linesOfParagraph">linesOfParagraph</a>(). The length of the entire text in characters is returned by <a href="q3textedit.html#length-prop">length</a>().</p>
<p>You can scroll to an anchor in the text, e.g. <tt><a name="anchor"></tt> with <a href="q3textedit.html#scrollToAnchor">scrollToAnchor</a>(). The <a href="q3textedit.html#find">find</a>() function can be used to find and select a given string within the text.</p>
<p>A read-only Q3TextEdit provides the same functionality as the (obsolete) <a href="porting4.html#qtextview">QTextView</a>. (<a href="porting4.html#qtextview">QTextView</a> is still supplied for compatibility with old code.)</p>
<a name="read-only-key-bindings"></a>
<h4>Read-only key bindings</h4>
<p>When Q3TextEdit is used read-only the key-bindings are limited to navigation, and text may only be selected with the mouse:</p>
<table class="generic">
<thead><tr class="qt-style"><th >Keypresses</th><th >Action</th></tr></thead>
<tr valign="top" class="odd"><td >Up</td><td >Move one line up</td></tr>
<tr valign="top" class="even"><td >Down</td><td >Move one line down</td></tr>
<tr valign="top" class="odd"><td >Left</td><td >Move one character left</td></tr>
<tr valign="top" class="even"><td >Right</td><td >Move one character right</td></tr>
<tr valign="top" class="odd"><td >PageUp</td><td >Move one (viewport) page up</td></tr>
<tr valign="top" class="even"><td >PageDown</td><td >Move one (viewport) page down</td></tr>
<tr valign="top" class="odd"><td >Home</td><td >Move to the beginning of the text</td></tr>
<tr valign="top" class="even"><td >End</td><td >Move to the end of the text</td></tr>
<tr valign="top" class="odd"><td >Shift+Wheel</td><td >Scroll the page horizontally (the Wheel is the mouse wheel)</td></tr>
<tr valign="top" class="even"><td >Ctrl+Wheel</td><td >Zoom the text</td></tr>
</table>
<p>The text edit may be able to provide some meta-information. For example, the <a href="q3textedit.html#documentTitle-prop">documentTitle</a>() function will return the text from within HTML <tt><title></tt> tags.</p>
<p>The text displayed in a text edit has a <i>context</i>. The context is a path which the text edit's <a href="q3mimesourcefactory.html">Q3MimeSourceFactory</a> uses to resolve the locations of files and images. It is passed to the <a href="q3textedit.html#mimeSourceFactory">mimeSourceFactory</a>() when quering data. (See <a href="q3textedit.html#Q3TextEdit">Q3TextEdit</a>() and <a href="q3textedit.html#context">context</a>().)</p>
<a name="logtextmode"></a><a name="using-q3textedit-in-qt-logtext-mode"></a>
<h4>Using Q3TextEdit in Qt::LogText Mode</h4>
<p>Setting the text format to <a href="qt.html#TextFormat-enum">Qt::LogText</a> puts the widget in a special mode which is optimized for very large texts. In this mode editing and rich text support are disabled (the widget is explicitly set to read-only mode). This allows the text to be stored in a different, more memory efficient manner. However, a certain degree of text formatting is supported through the use of formatting tags. A tag is delimited by <tt><</tt> and <tt>></tt>. The characters <tt><</tt>, <tt>></tt> and <tt>&</tt> are escaped by using <tt>&lt;</tt>, <tt>&gt;</tt> and <tt>&amp;</tt>. A tag pair consists of a left and a right tag (or open/close tags). Left-tags mark the starting point for formatting, while right-tags mark the ending point. A right-tag always start with a <tt>/</tt> before the tag keyword. For example <tt><b></tt> and <tt></b></tt> are a tag pair. Tags can be nested, but they have to be closed in the same order as they are opened. For example, <tt><b><u></u></b></tt> is valid, while <tt><b><u></b></u></tt> will output an error message.</p>
<p>By using tags it is possible to change the color, bold, italic and underline settings for a piece of text. A color can be specified by using the HTML font tag <tt><font color=colorname></tt>. The color name can be one of the color names from the X11 color database, or a RGB hex value (e.g <tt>#00ff00</tt>). Example of valid color tags: <tt><font color=red></tt>, <tt><font color="light blue"></tt>,<tt><font color="#223344"></tt>. Bold, italic and underline settings can be specified by the tags <tt><b></tt>, <tt><i></tt> and <tt><u></tt>. Note that a tag does not necessarily have to be closed. A valid example:</p>
<pre class="cpp"> This is <span class="operator"><</span>font color<span class="operator">=</span>red<span class="operator">></span>red<span class="operator"><</span><span class="operator">/</span>font<span class="operator">></span> <span class="keyword">while</span> <span class="operator"><</span>b<span class="operator">></span><span class="keyword">this</span><span class="operator"><</span><span class="operator">/</span>b<span class="operator">></span> is <span class="operator"><</span>font color<span class="operator">=</span>blue<span class="operator">></span>blue<span class="operator"><</span><span class="operator">/</span>font<span class="operator">></span><span class="operator">.</span>
<span class="operator"><</span>font color<span class="operator">=</span>green<span class="operator">></span><span class="operator"><</span>font color<span class="operator">=</span>yellow<span class="operator">></span>Yellow<span class="operator">,</span><span class="operator"><</span><span class="operator">/</span>font<span class="operator">></span> <span class="keyword">and</span> <span class="operator"><</span>u<span class="operator">></span>green<span class="operator"><</span><span class="operator">/</span>u<span class="operator">></span><span class="operator">.</span></pre>
<p>Stylesheets can also be used in <a href="qt.html#TextFormat-enum">Qt::LogText</a> mode. To create and use a custom tag, you could do the following:</p>
<pre class="cpp"> <span class="type">Q3TextEdit</span> <span class="operator">*</span> log <span class="operator">=</span> <span class="keyword">new</span> <span class="type">Q3TextEdit</span>(<span class="keyword">this</span>);
log<span class="operator">-</span><span class="operator">></span><a href="q3textedit.html#textFormat-prop">setTextFormat</a>(<span class="type"><a href="qt.html">Qt</a></span><span class="operator">::</span>LogText);
<span class="type"><a href="q3stylesheetitem.html">Q3StyleSheetItem</a></span> <span class="operator">*</span> item <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="q3stylesheetitem.html">Q3StyleSheetItem</a></span>(log<span class="operator">-</span><span class="operator">></span>styleSheet()<span class="operator">,</span> <span class="string">"mytag"</span>);
item<span class="operator">-</span><span class="operator">></span><a href="q3textedit.html#setColor">setColor</a>(<span class="string">"red"</span>);
item<span class="operator">-</span><span class="operator">></span>setFontWeight(<span class="type"><a href="qfont.html">QFont</a></span><span class="operator">::</span>Bold);
item<span class="operator">-</span><span class="operator">></span>setFontUnderline(<span class="keyword">true</span>);
log<span class="operator">-</span><span class="operator">></span><a href="q3textedit.html#append">append</a>(<span class="string">"This is a <mytag>custom tag</mytag>!"</span>);</pre>
<p>Note that only the color, bold, underline and italic attributes of a <a href="q3stylesheetitem.html">Q3StyleSheetItem</a> is used in <a href="qt.html#TextFormat-enum">Qt::LogText</a> mode.</p>
<p>Note that you can use setMaxLogLines() to limit the number of lines the widget can hold in <a href="qt.html#TextFormat-enum">Qt::LogText</a> mode.</p>
<p>There are a few things that you need to be aware of when the widget is in this mode:</p>
<ul>
<li>Functions that deal with rich text formatting and cursor movement will not work or return anything valid.</li>
<li>Lines are equivalent to paragraphs.</li>
</ul>

<h3>Using Q3TextEdit as an Editor</h3>
<p>All the information about using Q3TextEdit as a display widget also applies here.</p>
<p>The current format's attributes are set with <a href="q3textedit.html#setItalic">setItalic</a>(), <a href="q3textedit.html#setBold">setBold</a>(), <a href="q3textedit.html#setUnderline">setUnderline</a>(), <a href="q3textedit.html#setFamily">setFamily</a>() (font family), <a href="q3textedit.html#setPointSize">setPointSize</a>(), <a href="q3textedit.html#setColor">setColor</a>() and <a href="q3textedit.html#setCurrentFont">setCurrentFont</a>(). The current paragraph's alignment is set with <a href="q3textedit.html#setAlignment">setAlignment</a>().</p>
<p>Use <a href="q3textedit.html#setSelection">setSelection</a>() to select text. The <a href="q3textedit.html#setSelectionAttributes">setSelectionAttributes</a>() function is used to indicate how selected text should be displayed. Use <a href="q3textedit.html#hasSelectedText-prop">hasSelectedText</a>() to find out if any text is selected. The currently selected text's position is available using <a href="q3textedit.html#getSelection">getSelection</a>() and the selected text itself is returned by <a href="q3textedit.html#selectedText-prop">selectedText</a>(). The selection can be copied to the clipboard with <a href="q3textedit.html#copy">copy</a>(), or cut to the clipboard with <a href="q3textedit.html#cut">cut</a>(). It can be deleted with <a href="q3textedit.html#removeSelectedText">removeSelectedText</a>(). The entire text can be selected (or unselected) using <a href="q3textedit.html#selectAll">selectAll</a>(). Q3TextEdit supports multiple selections. Most of the selection functions operate on the default selection, selection 0. If the user presses a non-selecting key, e.g. a cursor key without also holding down Shift, all selections are cleared.</p>
<p>Set and get the position of the cursor with <a href="q3textedit.html#setCursorPosition">setCursorPosition</a>() and <a href="q3textedit.html#getCursorPosition">getCursorPosition</a>() respectively. When the cursor is moved, the signals <a href="q3textedit.html#currentFontChanged">currentFontChanged</a>(), <a href="q3textedit.html#currentColorChanged">currentColorChanged</a>() and <a href="q3textedit.html#currentAlignmentChanged">currentAlignmentChanged</a>() are emitted to reflect the font, color and alignment at the new cursor position.</p>
<p>If the text changes, the <a href="q3textedit.html#textChanged">textChanged</a>() signal is emitted, and if the user inserts a new line by pressing Return or Enter, <a href="q3textedit.html#returnPressed">returnPressed</a>() is emitted. The <a href="q3textedit.html#modified-prop">isModified</a>() function will return true if the text has been modified.</p>
<p>Q3TextEdit provides command-based undo and redo. To set the depth of the command history use <a href="q3textedit.html#undoDepth-prop">setUndoDepth</a>() which defaults to 100 steps. To undo or redo the last operation call <a href="q3textedit.html#undo">undo</a>() or <a href="q3textedit.html#redo">redo</a>(). The signals <a href="q3textedit.html#undoAvailable">undoAvailable</a>() and <a href="q3textedit.html#redoAvailable">redoAvailable</a>() indicate whether the undo and redo operations can be executed.</p>

</table>
<p>To select (mark) text hold down the Shift key whilst pressing one of the movement keystrokes, for example, <i>Shift+Right</i> will select the character to the right, and <i>Shift+Ctrl+Right</i> will select the word to the right, etc.</p>
<p>By default the text edit widget operates in insert mode so all text that the user enters is inserted into the text edit and any text to the right of the cursor is moved out of the way. The mode can be changed to overwrite, where new text overwrites any text to the right of the cursor, using <a href="q3textedit.html#overwriteMode-prop">setOverwriteMode</a>().</p>

<p><a href="q3textedit.html" class="compat">Q3TextEdit</a> is optimized for large amounts text. One of its optimizations is to format only the visible text, formatting the rest on demand, e.g. as the user scrolls, so you don't usually need to call this function.</p>
<p>In some situations you may want to force the whole text to be formatted. For example, if after calling <a href="q3textedit.html#text-prop">setText</a>(), you wanted to know the height of the document (using <a href="q3scrollview.html#contentsHeight-prop">contentsHeight</a>()), you would call this function first.</p>
