+    \class QLabel
+    \brief The QLabel widget provides a text or image display.
+
+    \ingroup basicwidgets
+    \ingroup text
+    \mainclass
+
+    QLabel is used for displaying text or an image. No user
+    interaction functionality is provided. The visual appearance of
+    the label can be configured in various ways, and it can be used
+    for specifying a focus mnemonic key for another widget.
+
+    A QLabel can contain any of the following content types:
+
+    \table
+    \header \o Content \o Setting
+    \row \o Plain text
+         \o Pass a QString to setText().
+    \row \o Rich text
+         \o Pass a QString that contains rich text to setText().
+    \row \o A pixmap
+         \o Pass a QPixmap to setPixmap().
+    \row \o A movie
+         \o Pass a QMovie to setMovie().
+    \row \o A number
+         \o Pass an \e int or a \e double to setNum(), which converts
+            the number to plain text.
+    \row \o Nothing
+         \o The same as an empty plain text. This is the default. Set
+            by clear().
+    \endtable
+
+    When the content is changed using any of these functions, any
+    previous content is cleared.
+
+    By default, labels display \l{alignment}{left-aligned, vertically-centered}
+    text and images, where any tabs in the text to be displayed are
+    \l{Qt::TextExpandTabs}{automatically expanded}. However, the look
+    of a QLabel can be adjusted and fine-tuned in several ways.
+
+    The positioning of the content within the QLabel widget area can
+    be tuned with setAlignment() and setIndent(). Text content can
+    also wrap lines along word boundaries with setWordWrap(). For
+    example, this code sets up a sunken panel with a two-line text in
+    the bottom right corner (both lines being flush with the right
+    side of the label):
+
+    \snippet doc/src/snippets/code/src_gui_widgets_qlabel.cpp 0
+
+    The properties and functions QLabel inherits from QFrame can also
+    be used to specify the widget frame to be used for any given label.
+
+    A QLabel is often used as a label for an interactive widget. For
+    this use QLabel provides a useful mechanism for adding an
+    mnemonic (see QKeySequence) that will set the keyboard focus to
+    the other widget (called the QLabel's "buddy"). For example:
+
+    \snippet doc/src/snippets/code/src_gui_widgets_qlabel.cpp 1
+
+    In this example, keyboard focus is transferred to the label's
+    buddy (the QLineEdit) when the user presses Alt+P. If the buddy
+    was a button (inheriting from QAbstractButton), triggering the
+    mnemonic would emulate a button click.
