     \brief The QTextEdit widget provides a powerful single-page rich text editor.

     \section1 Introduction and Concepts
 
     QTextEdit 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.
 
     QTextEdit has three modes of operation:
     \table
     \header \i Mode \i Command \i Notes
     \row \i Plain Text Editor \i setTextFormat(PlainText)
 	 \i Set text with setText(); text() returns plain text. Text
 	 attributes (e.g. colors) can be set, but plain text is always
 	 returned.<sup>1.</sup>
     \row \i Rich Text Editor \i setTextFormat(RichText)
 	 \i Set text with setText(); text() 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. <sup>2.</sup>
     \row \i Text Viewer<sup>3.</sup> \i setReadOnly(TRUE)
          \i Set text with setText() or append() (which has no undo
 	 history so is faster and uses less memory); text() returns
 	 plain or rich text depending on the textFormat(). This mode
 	 can correctly display a large subset of HTML tags.
     \endtable
 
     <sup>1.</sup><small>We do \e not recommend using QTextEdit to
     create syntax highlighting editors because the current API is
     insufficient for this purpose. We hope to release a more complete
     API that will support syntax highlighting in a later
     release.</small>
 
     <sup>2.</sup><small>A more complete API that supports setting
     margins, images, etc., is planned for a later Qt release.</small>
 
     <sup>3.</sup><small>Qt 3.1 will provide a Log Viewer mode which is
     optimised for the fast and memory efficient display of large
     amounts of read only text.</small>
 
     We recommend that you always call setTextFormat() to set the mode
     you want to use. If you use \c AutoText then setText() and
     append() will try to determine whether the text they are given is
     plain text or rich text. If you use \c RichText then setText() and
     append() will assume that the text they are given is rich text.
     insert() simply inserts the text it is given.
 
     QTextEdit 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, two newlines
     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
     alignment(). Paragraphs are separated by hard line breaks. Each
     character within a paragraph has its own attributes, for example,
     font and color.
 
     The text edit documentation uses the following concepts:
     \list
     \i \e{current format} --
     this is the format at the current cursor position, \e and it
     is the format of the selected text if any.
     \i \e{current paragraph} -- the paragraph which contains the
     cursor.
     \endlist
 
     QTextEdit can display images (using QMimeSourceFactory), lists and
     tables. If the text is too large to view within the text edit's
     viewport, scrollbars 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
     styleSheet(). Custom tags can be created and placed in a custom
     style sheet. Change the style sheet with \l{setStyleSheet()}; see
     QStyleSheet for details. The images identified by image tags are
     displayed if they can be interpreted using the text edit's
     \l{QMimeSourceFactory}; see setMimeSourceFactory().
 
     If you want a text browser with more navigation use QTextBrowser.
     If you just need to display a small piece of rich text use QLabel
     or QSimpleRichText.
 
     If you create a new QTextEdit, and want to allow the user to edit
     rich text, call setTextFormat(Qt::RichText) to ensure that the
     text is treated as rich text. (Rich text uses HTML tags to set
     text formatting attributes. See QStyleSheet for information on the
     HTML tags that are supported.). If you don't call setTextFormat()
     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(Qt::PlainText) to preserve such
     text.
 
     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.
     \section1 Using QTextEdit as a Display Widget
 
     QTextEdit can display a large HTML subset, including tables and
     images.
 
     The text is set or replaced using setText() which deletes any
     existing text and replaces it with the text passed in the
     setText() call. If you call setText() with legacy HTML (with
     setTextFormat(RichText) in force), and then call text(), the text
     that is returned may have different markup, but will render the
     same. Text can be inserted with insert(), paste(), pasteSubType()
     and append(). Text that is appended does not go into the undo
     history; this makes append() faster and consumes less memory. Text
     can also be cut(). The entire text is deleted with clear() and the
     selected text is deleted with removeSelectedText(). Selected
     (marked) text can also be deleted with del() (which will delete
     the character to the right of the cursor if no text is selected).
 
     Loading and saving text is achieved using setText() and text(),
     for example:
     \code
     QFile file( fileName ); // Read the text from a file
     if ( file.open( IO_ReadOnly ) ) {
 	QTextStream ts( &file );
 	textEdit->setText( ts.read() );
     }
     \endcode
     \code
     QFile file( fileName ); // Write the text to a file
     if ( file.open( IO_WriteOnly ) ) {
 	QTextStream ts( &file );
 	ts << textEdit->text();
 	textEdit->setModified( FALSE );
     }
     \endcode
 
     By default the text edit wraps words at whitespace to fit within
     the text edit widget. The setWordWrap() function is used to
     specify the kind of word wrap you want, or \c NoWrap if you don't
     want any wrapping.  Call setWordWrap() to set a fixed pixel width
     \c FixedPixelWidth, or character column (e.g. 80 column) \c
     FixedColumnWidth with the pixels or columns specified with
     setWrapColumnOrWidth(). If you use word wrap to the widget's width
     \c WidgetWidth, you can specify whether to break on whitespace or
     anywhere with setWrapPolicy().
 
     The background color is set differently than other widgets, using
     setPaper(). You specify a brush style which could be a plain color
     or a complex pixmap.
 
     Hypertext links are automatically underlined; this can be changed
     with setLinkUnderline(). The tab stop width is set with
     setTabStopWidth().
 
     The zoomIn() and zoomOut() functions can be used to resize the
     text by increasing (decreasing for zoomOut()) the point size used.
     Images are not affected by the zoom functions.
 
     The lines() function returns the number of lines in the text and
     paragraphs() returns the number of paragraphs. The number of lines
     within a particular paragraph is returned by linesOfParagraph().
     The length of the entire text in characters is returned by
     length().
 
     You can scroll to an anchor in the text, e.g. \c{<a
     name="anchor">} with scrollToAnchor(). The find() function can be
     used to find and select a given string within the text.
 
     A read-only QTextEdit provides the same functionality as the
     (obsolete) QTextView. (QTextView is still supplied for
     compatibility with old code.)
 
     \section2 Read-only key bindings
 
     When QTextEdit is used read-only the key-bindings are limited to
     navigation, and text may only be selected with the mouse:
     \table
     \header \i Keypresses \i Action
     \row \i \e{UpArrow} \i Move one line up
     \row \i \e{DownArrow} \i Move one line down
     \row \i \e{LeftArrow} \i Move one character left
     \row \i \e{RightArrow} \i Move one character right
     \row \i \e{PageUp} \i Move one (viewport) page up
     \row \i \e{PageDown} \i Move one (viewport) page down
     \row \i \e{Home} \i Move to the beginning of the text
     \row \i \e{End} \i Move to the end of the text
     \row \i \e{Shift+Wheel} \i Scroll the page horizontally (the Wheel is the mouse wheel)
     \row \i \e{Ctrl+Wheel} \i Zoom the text
     \endtable
 
     The text edit may be able to provide some meta-information. For
     example, the documentTitle() function will return the text from
     within HTML \c{<title>} tags.
 
     The text displayed in a text edit has a \e context. The context is
     a path which the text edit's QMimeSourceFactory uses to resolve
     the locations of files and images. It is passed to the
     mimeSourceFactory() when quering data. (See QTextEdit() and
     \l{context()}.)
 
     \section1 Using QTextEdit as an Editor
 
     All the information about using QTextEdit as a display widget also
     applies here.
 
     The current format's attributes are set with setItalic(),
     setBold(), setUnderline(), setFamily() (font family),
     setPointSize(), setColor() and setCurrentFont().  The current
     paragraph's alignment is set with setAlignment().
 
     Use setSelection() to select text. The setSelectionAttributes()
     function is used to indicate how selected text should be
     displayed. Use hasSelectedText() to find out if any text is
     selected. The currently selected text's position is available
     using getSelection() and the selected text itself is returned by
     selectedText(). The selection can be copied to the clipboard with
     copy(), or cut to the clipboard with cut(). It can be deleted with
     removeSelectedText(). The entire text can be selected (or
     unselected) using selectAll(). QTextEdit 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.
 
     Set and get the position of the cursor with setCursorPosition()
     and getCursorPosition() respectively. When the cursor is moved,
     the signals currentFontChanged(), currentColorChanged() and
     currentAlignmentChanged() are emitted to reflect the font, color
     and alignment at the new cursor position.
 
     If the text changes, the textChanged() signal is emitted, and if
     the user inserts a new line by pressing Return or Enter,
     returnPressed() is emitted. The isModified() function will return
     TRUE if the text has been modified.
 
     QTextEdit provides command-based undo and redo. To set the depth
     of the command history use setUndoDepth() which defaults to 100
     steps. To undo or redo the last operation call undo() or redo().
     The signals undoAvailable() and redoAvailable() indicate whether
     the undo and redo operations can be executed.
 
     The indent() function is used to reindent a paragraph. It is
     useful for code editors, for example in <em>Qt Designer</em>'s
     code editor \e{Ctrl+I} invokes the indent() function.
 
     \section2 Editing key bindings
 
     The list of key-bindings which are implemented for editing:
     \table
     \header \i Keypresses \i Action
     \row \i \e{Backspace} \i Delete the character to the left of the cursor
     \row \i \e{Delete} \i Delete the character to the right of the cursor
     \row \i \e{Ctrl+A} \i Move the cursor to the beginning of the line
     \row \i \e{Ctrl+B} \i Move the cursor one character left
     \row \i \e{Ctrl+C} \i Copy the marked text to the clipboard (also
 			  \e{Ctrl+Insert} under Windows)
     \row \i \e{Ctrl+D} \i Delete the character to the right of the cursor
     \row \i \e{Ctrl+E} \i Move the cursor to the end of the line
     \row \i \e{Ctrl+F} \i Move the cursor one character right
     \row \i \e{Ctrl+H} \i Delete the character to the left of the cursor
     \row \i \e{Ctrl+K} \i Delete to end of line
     \row \i \e{Ctrl+N} \i Move the cursor one line down
     \row \i \e{Ctrl+P} \i Move the cursor one line up
     \row \i \e{Ctrl+V} \i Paste the clipboard text into line edit
 			  (also \e{Shift+Insert} under Windows)
     \row \i \e{Ctrl+X} \i Cut the marked text, copy to clipboard
 			  (also \e{Shift+Delete} under Windows)
     \row \i \e{Ctrl+Z} \i Undo the last operation
     \row \i \e{Ctrl+Y} \i Redo the last operation
     \row \i \e{LeftArrow} \i Move the cursor one character left
     \row \i \e{Ctrl+LeftArrow} \i Move the cursor one word left
     \row \i \e{RightArrow} \i Move the cursor one character right
     \row \i \e{Ctrl+RightArrow} \i Move the cursor one word right
     \row \i \e{UpArrow} \i Move the cursor one line up
     \row \i \e{Ctrl+UpArrow} \i Move the cursor one word up
     \row \i \e{DownArrow} \i Move the cursor one line down
     \row \i \e{Ctrl+Down Arrow} \i Move the cursor one word down
     \row \i \e{PageUp} \i Move the cursor one page up
     \row \i \e{PageDown} \i Move the cursor one page down
     \row \i \e{Home} \i Move the cursor to the beginning of the line
     \row \i \e{Ctrl+Home} \i Move the cursor to the beginning of the text
     \row \i \e{End} \i Move the cursor to the end of the line
     \row \i \e{Ctrl+End} \i Move the cursor to the end of the text
     \row \i \e{Shift+Wheel} \i Scroll the page horizontally
 			       (the Wheel is the mouse wheel)
     \row \i \e{Ctrl+Wheel} \i Zoom the text
     \endtable
 
     To select (mark) text hold down the Shift key whilst pressing one
     of the movement keystrokes, for example, <i>Shift+Right Arrow</i>
     will select the character to the right, and <i>Shift+Ctrl+Right
     Arrow</i> will select the word to the right, etc.
 
     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 setOverwriteMode().

     \c{<img src="image.png">}, and the context is "path/to/look/in", the
     QMimeSourceFactory will try to load the image from
     "path/to/look/in/image.png". If the tag was
     \c{<img src="/image.png">}, the context will not be used (because
     QMimeSourceFactory recognizes that we have used an absolute path)
     and will try to load "/image.png". The context is applied in exactly
     the same way to \e hrefs, for example,
     \c{<a href="target.html">Target</a>}, would resolve to
     "path/to/look/in/target.html".
