     \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:

     <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.

     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() );
+    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 );
+    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

     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.

     \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)
+                   (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().
