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. - - <img src=qheader-m.png> <img src=qheader-w.png> - - \sa TQListView TQTable -*/ - - - -/*! - Constructs a horizontal header called \a name, with parent \a - parent. -*/ - -TQHeader::TQHeader( TQWidget *parent, const char *name ) - : TQWidget( parent, name, TQt::WStaticContents ) -{ - orient = Qt::Horizontal; - init( 0 ); -} - -/*! - Constructs a horizontal header called \a name, with \a n sections - and parent \a parent. -*/ - -TQHeader::TQHeader( int n, TQWidget *parent, const char *name ) - : TQWidget( parent, name, TQt::WStaticContents ) -{ - orient = Qt::Horizontal; - init( n ); -} - -/*! - Destroys the header and all its sections. -*/ - -TQHeader::~TQHeader() -{ - delete d; - d = 0; -} - -/*! \reimp - */ - -void TQHeader::showEvent( TQShowEvent *e ) -{ - calculatePositions(); - TQWidget::showEvent( e ); -} - -/*! - \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.
