Unlike QSimpleRichText, which merely draws small pieces of rich text, a QTextView is a real widget, with scrollbars when necessary, for showing large text documents.
The rendering style and available tags are defined by a styleSheet(). Currently, a small XML/CSS1 subset including embedded images and tables is supported. See QStyleSheet for details. Possible images within the text document are resolved by using a QMimeSourceFactory. See setMimeSourceFactory() for details.
Using QTextView is quite similar to QLabel. It's mainly a call to setText() to set the contents. Setting the background color is slightly different from other widgets, since a text view is a scrollable widget that naturally provides a scrolling background. You can specify the colorgroup of the displayed text with setPaperColorGroup() or directly define the paper background with setPaper(). QTextView supports both plain color and complex pixmap backgrounds.
Note that we do not intend to add a full-featured web browser widget to Qt (since that would easily double Qt's size and only few applications would benefit from it). In particular, the rich text support in Qt is supposed to provide a fast, portable and sufficient way to add reasonable online help facilities to applications. We will, however, extend it to some degree in future versions of Qt.
For even more, like hypertext capabilities, see QTextBrowser.

Appends text to the current text.
Useful for log viewers.

Returns the context of the view.

Copies the marked text to the clipboard.
Returns the document title parsed from the content.

Returns TRUE if there is any text selected, FALSE otherwise.
See also selectedText().
[virtual]
Returns the height of the view given a width of w.

Provides scrolling and paging.
Reimplemented from QWidget.
Returns the current link color.
The color may either have been set with setLinkColor() or stem from the document's body tag.
See also setLinkColor().
Returns wether or not links should be displayed underlined.
Returns the current mime source factory for the view.
See also setMimeSourceFactory().

Returns the brush used to paint the background.
Returns the brush used to paint the background.
Returns the colorgroup of the paper.

[protected]
Returns the document defining the view as drawable and queryable rich text object. This is not currently useful for applications.
[slot]
Selects all text.
Returns a copy of the selected text in plain text format.
See also hasSelectedText().
Sets the color used to display links in the document to col.
See also linkColor().
Defines wether or not links should be displayed underlined.
Sets the mime source factory for the view. The factory is used to resolve named references within rich text documents. If no factory has been specified, the text view uses the default factory QMimeSourceFactory::defaultFactory().
Ownership of factory is not transferred to make it possible for several text view widgets to share the same mime source.
See also mimeSourceFactory().
Sets the brush to use as the background to pap.
This may be a nice parchment or marble pixmap or simply another plain color.
Technically, setPaper() is just a convenience function to set the base brush of the paperColorGroup().
See also paper().
Sets the full colorgroup of the paper to colgrp. If not specified otherwise in the document itself, any text will use QColorGroup::text(). The background will be painted with QColorGroup::brush(QColorGroup::Base).
See also paperColorGroup() and setPaper().
Sets the style sheet of the view.
See also styleSheet().
[virtual]
Changes the contents of the view to the string text and the context to context.
text may be interpreted either as plain text or as rich text,
depending on the textFormat(). The default setting is AutoText,
i.e. the text view autodetects the format from text.
The optional context is used to resolve references within the text document, for example image sources. It is passed directly to the mimeSourceFactory() when quering data.
See also text() and setTextFormat().
Reimplemented in QTextBrowser.
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Changes the contents of the view to the string text.
text may be interpreted either as plain text or as rich text,
depending on the textFormat(). The default setting is AutoText,
i.e. the text view autodetects the format from text.
This function calls setText( text, QString::null ), i.e. it sets a text without any context.
See also text() and setTextFormat().
Sets the text format to format. Possible choices are
PlainText
- all characters are displayed verbatim,
including all blanks and linebreaks.
RichText
- rich text rendering. The available
styles are defined in the default stylesheet
QStyleSheet::defaultSheet().
AutoText
- this is also the default. The label
autodetects which rendering style suits best, PlainText
or RichText.
Technically, this is done by using the
QStyleSheet::mightBeRichText() heuristic.
