    \class TQHeader tqheader.h
    \brief The TQHeader class provides a header row or column, e.g. for
    tables and listviews.

    \ingroup advanced

    This class provides a header, e.g. a vertical header to display
    row labels, or a horizontal header to display column labels. It is
    used by TQTable and TQListView for example.

    A header is composed of one or more \e sections, each of which can
    display a text label and an \link TQIconSet iconset\endlink. A sort
    indicator (an arrow) can also be displayed using
    setSortIndicator().

    Sections are added with addLabel() and removed with removeLabel().
    The label and iconset are set in addLabel() and can be changed
    later with setLabel(). Use count() to retrieve the number of
    sections in the header.

    The orientation of the header is set with setOrientation(). If
    setStretchEnabled() is TRUE, the sections will expand to take up
    the full width (height for vertical headers) of the header. The
    user can resize the sections manually if setResizeEnabled() is
    TRUE. Call adjustHeaderSize() to have the sections resize to
    occupy the full width (or height).

    A section can be moved with moveSection(). If setMovingEnabled()
    is TRUE (the default)the user may drag a section from one position
    to another. If a section is moved, the index positions at which
    sections were added (with addLabel()), may not be the same after the
    move. You don't have to worry about this in practice because the
    TQHeader API works in terms of section numbers, so it doesn't matter
    where a particular section has been moved to.

    If you want the current index position of a section call
    mapToIndex() giving it the section number. (This is the number
    returned by the addLabel() call which created the section.) If you
    want to get the section number of a section at a particular index
    position call mapToSection() giving it the index number.

    Here's an example to clarify mapToSection() and mapToIndex():

    \table
    \header \i41 Index positions
    \row \i 0 \i 1 \i 2 \i 3
    \header \i41 Original section ordering
    \row \i Sect 0 \i Sect 1 \i Sect 2 \i Sect 3
    \header \i41 Ordering after the user moves a section
    \row \i Sect 0 \i Sect 2 \i Sect 3 \i Sect 1
    \endtable

    \table
    \header \i \e k \i mapToSection(\e k) \i mapToIndex(\e k)
    \row \i 0 \i 0 \i 0
    \row \i 1 \i 2 \i 3
    \row \i 2 \i 3 \i 1
    \row \i 3 \i 1 \i 2
    \endtable

    In the example above, if we wanted to find out which section is at
    index position 3 we'd call mapToSection(3) and get a section
    number of 1 since section 1 was moved. Similarly, if we wanted to
    know which index position section 2 occupied we'd call
    mapToIndex(2) and get an index of 1.

    TQHeader provides the clicked(), pressed() and released() Q_SIGNALS.
    If the user changes the size of a section, the sizeChange() signal
    is emitted. If you want to have a sizeChange() signal emitted
    continuously whilst the user is resizing (rather than just after
    the resizing is finished), use setTracking(). If the user moves a
    section the indexChange() signal is emitted.

    \fn void TQHeader::sizeChange( int section, int oldSize, int newSize )

    This signal is emitted when the user has changed the size of a \a
    section from \a oldSize to \a newSize. This signal is typically
    connected to a slot that repaints the table or list that contains
