<hr><a name="details"></a><h2>Detailed Description</h2>
The QTextEdit widget provides a sophisticated single-page rich text editor.
<p>
<p> QTextEdit is an advanced WYSIWYG editor supporting rich text
formatting. It is optimized to handle large documents and to respond
quickly to user input.
<p> Internally QTextEdit works on paragraphs and characters. A paragraph
is a formatted string which is word-wrapped to fit into the width of
the widget. The words in the paragraph are aligned in accordance
with the paragraph's <a href="#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> QTextEdit can display images (using <a href="qmimesourcefactory.html">QMimeSourceFactory</a>), 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 <a href="#styleSheet">styleSheet</a>().
Change the style sheet with <a href="#setStyleSheet">setStyleSheet</a>(); see <a href="qstylesheet.html">QStyleSheet</a>
for details. The images identified by image tags are displayed if
they can be interpreted using the text edit's
<a href="qmimesourcefactory.html">QMimeSourceFactory</a>; see <a href="#setMimeSourceFactory">setMimeSourceFactory</a>().
<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="qsimplerichtext.html">QSimpleRichText</a>.
<p> If you create a new QTextEdit, and want to allow the user to edit
rich text, call <a href="#setTextFormat">setTextFormat</a>(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.
<p> The text edit documentation uses the following concepts:
<ul>
<li> <i>current format</i> --
this is the format at the current cursor position, <em>and</em> it
is the format of the selected text if any.
<li> <i>current paragraph</i> -- the paragraph which contains the
cursor.
</ul>
<p> The text is set or replaced using <a href="#setText">setText</a>() which deletes any
existing text and replaces it with the text passed in the setText()
call. Text can be inserted with <a href="#insert">insert</a>(), <a href="#paste">paste</a>() and
<a href="#pasteSubType">pasteSubType</a>(). Text can also be <a href="#cut">cut</a>(). The entire text is deleted
with <a href="#clear">clear</a>() and the selected text is deleted with
<a href="#removeSelectedText">removeSelectedText</a>(). Selected (marked) text can also be deleted
with <a href="#del">del</a>() (which will delete the character to the right of the
cursor if no text is selected).
<p> The current format's attributes are set with <a href="#setItalic">setItalic</a>(), <a href="#setBold">setBold</a>(),
<a href="#setUnderline">setUnderline</a>(), <a href="#setFamily">setFamily</a>() (font family), <a href="#setPointSize">setPointSize</a>(),
<a href="#setColor">setColor</a>() and <a href="#setCurrentFont">setCurrentFont</a>(). The current paragraph's style is
set with <a href="#setParagType">setParagType</a>() and its alignment is set with
<a href="#setAlignment">setAlignment</a>().
<p> Use <a href="#setSelection">setSelection</a>() to select text. The <a href="#setSelectionAttributes">setSelectionAttributes</a>()
function is used to indicate how selected text should be displayed.
Use <a href="#hasSelectedText">hasSelectedText</a>() to find out if any text is selected.
The currently selected text's position is available using
<a href="#getSelection">getSelection</a>() and the selected text itself is returned by
<a href="#selectedText">selectedText</a>(). The selection can be copied to the clipboard with
<a href="#copy">copy</a>(), or cut to the clipboard with <a href="#cut">cut</a>(). It can be deleted with
<a href="#removeSelectedText">removeSelectedText</a>(). The entire text can be selected (or
unselected) using <a href="#selectAll">selectAll</a>(). QTextEdit supports multiple
selections. Most of the selection functions operate on the default
selection, selection 0.
<p> Set and get the position of the cursor with <a href="#setCursorPosition">setCursorPosition</a>() and
<a href="#getCursorPosition">getCursorPosition</a>() respectively. When the cursor is moved, the
signals <a href="#currentFontChanged">currentFontChanged</a>(), <a href="#currentColorChanged">currentColorChanged</a>() and
<a href="#currentAlignmentChanged">currentAlignmentChanged</a>() are emitted to reflect the font, color and
alignment at the new cursor position.
<p> If the text changes, the <a href="#textChanged">textChanged</a>() signal is emitted, and if the
user inserts a new line by pressing Return or Enter, <a href="#returnPressed">returnPressed</a>()
is emitted. The <a href="#isModified">isModified</a>() function will return TRUE if the text
has been modified.
<p> QTextEdit provides command-based undo and redo. To set the depth of
the command history use <a href="#setUndoDepth">setUndoDepth</a>() which defaults to 100
steps. To undo or redo the last operation call <a href="#undo">undo</a>() or
<a href="#redo">redo</a>(). The signals <a href="#undoAvailable">undoAvailable</a>() and <a href="#redoAvailable">redoAvailable</a>() indicate
whether the undo and redo operations can be executed.
<p> The <a href="#indent">indent</a>() function is used to reindent a paragraph. It is useful
for code editors, for example in <em>Qt Designer</em>'s code editor
<em>Ctrl+I</em> invokes the indent() function.
<p> Loading and saving text is achieved using <a href="#setText">setText</a>() and <a href="#text">text</a>(), for
example:

<p> By default the text edit wraps words at whitespace to fit within
the text edit widget. The <a href="#setWordWrap">setWordWrap</a>() function is used to
specify the kind of word wrap you want, or <a href="#WordWrap-enum">NoWrap</a> if you don't
want any wrapping. Call setWordWrap() to set a fixed pixel width
<a href="#WordWrap-enum">FixedPixelWidth</a>, or character column (e.g. 80 column) <a href="#WordWrap-enum">FixedColumnWidth</a> with the pixels or columns specified with
<a href="#setWrapColumnOrWidth">setWrapColumnOrWidth</a>(). If you use word wrap to the widget's width
<a href="#WordWrap-enum">WidgetWidth</a>, you can specify whether to break on whitespace or
anywhere with <a href="#setWrapPolicy">setWrapPolicy</a>().
<p> The background color is set differently than other widgets, using
<a href="#setPaper">setPaper</a>(). You specify a brush style which could be a plain color
or a complex pixmap.
<p> Hypertext links are automatically underlined; this can be changed
with <a href="#setLinkUnderline">setLinkUnderline</a>(). The tab stop width is set with
<a href="#setTabStopWidth">setTabStopWidth</a>().
<p> The <a href="#zoomIn">zoomIn</a>() and <a href="#zoomOut">zoomOut</a>() 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.
<p> The <a href="#lines">lines</a>() function returns the number of lines in the text and
<a href="#paragraphs">paragraphs</a>() returns the number of paragraphs. The number of lines
within a particular paragraph is returned by <a href="#linesOfParagraph">linesOfParagraph</a>(). The
length of the entire text in characters is returned by <a href="#length">length</a>().
<p> You can scroll to an anchor in the text, e.g. <tt><a name="anchor"></tt>
with <a href="#scrollToAnchor">scrollToAnchor</a>(). The <a href="#find">find</a>() function can be used to find and
select a given string within the text.
<p> The list of key-bindings which are implemented for editing:
<ul>
<li> <i> Backspace </i> -- Delete the character to the left of the cursor
<li> <i> Delete </i> -- Delete the character to the right of the cursor
<li> <i> Ctrl+A </i> -- Move the cursor to the beginning of the line
<li> <i> Ctrl+B </i> -- Move the cursor one character left
<li> <i> Ctrl+C </i> -- Copy the marked text to the clipboard (also
<i>Ctrl+Insert</i> under Windows)
<li> <i> Ctrl+D </i> -- Delete the character to the right of the cursor
<li> <i> Ctrl+E </i> -- Move the cursor to the end of the line
<li> <i> Ctrl+F </i> -- Move the cursor one character right
<li> <i> Ctrl+H </i> -- Delete the character to the left of the cursor
<li> <i> Ctrl+K </i> -- Delete to end of line
<li> <i> Ctrl+N </i> -- Move the cursor one line down
<li> <i> Ctrl+P </i> -- Move the cursor one line up
<li> <i> Ctrl+V </i> -- Paste the clipboard text into line edit (also
<i>Shift+Insert</i> under Windows)
<li> <i> Ctrl+X </i> -- Cut the marked text, copy to clipboard (also
<i>Shift+Delete</i> under Windows)
<li> <i> Ctrl+Z </i> -- Undo the last operation
<li> <i> Ctrl+Y </i> -- Redo the last operation
<li> <i> Left Arrow </i> -- Move the cursor one character left
<li> <i> Ctrl+Left Arrow </i> -- Move the cursor one word left
<li> <i> Right Arrow </i> -- Move the cursor one character right
<li> <i> Ctrl+Right Arrow </i> -- Move the cursor one word right
<li> <i> Up Arrow </i> -- Move the cursor one line up
<li> <i> Ctrl+Up Arrow </i> -- Move the cursor one word up
<li> <i> Down Arrow </i> -- Move the cursor one line down
<li> <i> Ctrl+Down Arrow </i> -- Move the cursor one word down
<li> <i> Page Up </i> -- Move the cursor one page up
<li> <i> Page Down </i> -- Move the cursor one page down
<li> <i> Home </i> -- Move the cursor to the beginning of the line
<li> <i> Ctrl+Home Arrow </i> -- Move the cursor to the beginning of the text
<li> <i> End </i> -- Move the cursor to the end of the line
<li> <i> Ctrl+End Arrow </i> -- Move the cursor to the end of the text
<li> <i> Shift+Wheel</i> -- Scroll the page horizontally (the Wheel is
the mouse wheel)
<li> <i> Ctrl+Wheel</i> -- Zoom the text
</ul>
<p> 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.
<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="#setOverwriteMode">setOverwriteMode</a>().
<p> QTextEdit can also be used as read-only text viewer. Call
<a href="#setReadOnly">setReadOnly</a>( TRUE ) to disable editing. A read-only QTextEdit
provides the same functionality as the (obsolete) QTextView.
(QTextView is still supplied for compatibility with old code.)
<p> When QTextEdit is used read-only the key-bindings are limited to
navigation, and text may only be selected with the mouse:
<ul>
<li> <i> Up Arrow </i> -- Move one line up
<li> <i> Down Arrow </i> -- Move one line down
<li> <i> Left Arrow </i> -- Move one character left
<li> <i> Right Arrow </i> -- Move one character right
<li> <i> Page Up </i> -- Move one (viewport) page up
<li> <i> Page Down </i> -- Move one (viewport) page down
<li> <i> Home </i> -- Move to the beginning of the text
<li> <i> End </i> -- Move to the end of the text
<li> <i> Shift+Wheel</i> -- Scroll the page horizontally (the Wheel is
the mouse wheel)
<li> <i> Ctrl+Wheel</i> -- Zoom the text
</ul>
<p> The text edit may be able to provide some meta-information. For
example, the <a href="#documentTitle">documentTitle</a>() function will return the text from
within HTML <tt><title></tt> tags.
<p> The text displayed in a text edit has a <em>context</em>. The context is
a path which the text edit's <a href="qmimesourcefactory.html">QMimeSourceFactory</a> uses to resolve
the locations of files and images. It is passed to the
<a href="#mimeSourceFactory">mimeSourceFactory</a>() when quering data. (See QTextEdit() and
<a href="#context">context</a>().)
<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 <a href="helpsystem.html#online-help">online help</a> facilities to
applications, and to provide a basis for rich text editors.

<li><tt>QTextEdit::ActionDelete</tt> - Delete the character to the right of the cursor.
<li><tt>QTextEdit::ActionReturn</tt> - Split the paragraph at the cursor position.
<li><tt>QTextEdit::ActionKill</tt> - If the cursor is not at the end of the paragraph,
delete the text from the cursor position until the end of the
paragraph. If the cursor is at the end of the paragraph, delete the
hard line break at the end of the paragraph - this will cause this
paragraph to be joined with the following paragraph.

<h3 class=fn><a href="qstring.html">QString</a> <a name="text-prop"></a>text</h3>
<p>This property holds the text edit's text.
<p>There is no default text.
<p> On setting, any previous text is deleted.
<p> The text may be interpreted either as plain text or as rich text,
depending on the <a href="#textFormat">textFormat</a>(). The default setting is <a href="qt.html#TextFormat-enum">AutoText</a>,
i.e. the text edit autodetects the format of the text.
<p> For richtext, calling <a href="#text">text</a>() on an editable QTextEdit will cause the text
to be regenerated from the textedit. This may mean that the <a href="qstring.html">QString</a> returned
may not be exactly the same as the one that was set.
<p> <p>See also <a href="#textFormat-prop">textFormat</a>.
<p>Set this property's value with <a href="#setText">setText</a>() and get this property's value with <a href="#text">text</a>().
<h3 class=fn><a href="qt.html#TextFormat-enum">TextFormat</a> <a name="textFormat-prop"></a>textFormat</h3>
<p>This property holds the text format: rich text, plain text or auto text.
<p>The text format is one of the following:
<ul>
<li> PlainText - all characters, except newlines, are displayed
verbatim, including spaces. Whenever a newline appears in the text the
text edit inserts a hard line break and begins a new paragraph.
<li> RichText - rich text rendering. The available styles are
defined in the default stylesheet <a href="qstylesheet.html#defaultSheet">QStyleSheet::defaultSheet</a>().
<li> AutoText - this is the default. The text edit autodetects
which rendering style is best, <a href="qt.html#TextFormat-enum">PlainText</a> or <a href="qt.html#TextFormat-enum">RichText</a>. This is
done by using the <a href="qstylesheet.html#mightBeRichText">QStyleSheet::mightBeRichText</a>() function.
</ul>
<p>Set this property's value with <a href="#setTextFormat">setTextFormat</a>() and get this property's value with <a href="#textFormat">textFormat</a>().

<p>Set this property's value with <a href="#setUndoDepth">setUndoDepth</a>() and get this property's value with <a href="#undoDepth">undoDepth</a>().
<h3 class=fn>bool <a name="undoRedoEnabled-prop"></a>undoRedoEnabled</h3> <p>This property holds whether undo/redo is enabled.
<p>The default is TRUE.
<p>Set this property's value with <a href="#setUndoRedoEnabled">setUndoRedoEnabled</a>() and get this property's value with <a href="#isUndoRedoEnabled">isUndoRedoEnabled</a>().
<h3 class=fn><a href="qtextedit.html#WordWrap-enum">WordWrap</a> <a name="wordWrap-prop"></a>wordWrap</h3>
<p>This property holds the word wrap mode.
<p>The default mode is <a href="#WordWrap-enum">WidgetWidth</a> which causes words to be wrapped
at the right edge of the text edit. Wrapping occurs at whitespace,
keeping whole words intact. If you want wrapping to occur within
words use <a href="#setWrapPolicy">setWrapPolicy</a>(). If you set a wrap mode of <a href="#WordWrap-enum">FixedPixelWidth</a> or <a href="#WordWrap-enum">FixedColumnWidth</a> you should also call
<a href="#setWrapColumnOrWidth">setWrapColumnOrWidth</a>() with the width you want.
<p> <p>See also <a href="#WordWrap-enum">WordWrap</a>, <a href="#wrapColumnOrWidth-prop">wrapColumnOrWidth</a> and <a href="#wrapPolicy-prop">wrapPolicy</a>.
<p>Set this property's value with <a href="#setWordWrap">setWordWrap</a>() and get this property's value with <a href="#wordWrap">wordWrap</a>().
<h3 class=fn>int <a name="wrapColumnOrWidth-prop"></a>wrapColumnOrWidth</h3>

<p>If the wrap mode is <a href="#WordWrap-enum">FixedPixelWidth</a>, the value is the number
of pixels from the left edge of the text edit at which text should
be wrapped. If the wrap mode is <a href="#WordWrap-enum">FixedColumnWidth</a>, the value is
the column number (in character columns) from the left edge of the
text edit at which text should be wrapped.
<p> <p>See also <a href="#wordWrap-prop">wordWrap</a>.
<p>Set this property's value with <a href="#setWrapColumnOrWidth">setWrapColumnOrWidth</a>() and get this property's value with <a href="#wrapColumnOrWidth">wrapColumnOrWidth</a>().
<h3 class=fn><a href="qtextedit.html#WrapPolicy-enum">WrapPolicy</a> <a name="wrapPolicy-prop"></a>wrapPolicy</h3>
<p>This property holds the word wrap policy, at whitespace or anywhere.
<p>Defines where text can be wrapped when word wrap mode is not
<a href="#WordWrap-enum">NoWrap</a>. The choices are <a href="#WrapPolicy-enum">AtWhiteSpace</a> (the default) and <a href="#WrapPolicy-enum">Anywhere</a>.
<p> <p>See also <a href="#wordWrap-prop">wordWrap</a>.
<p>Set this property's value with <a href="#setWrapPolicy">setWrapPolicy</a>() and get this property's value with <a href="#wrapPolicy">wrapPolicy</a>().
