DESCRIPTION

       The QTabWidget class provides a stack of tabbed widgets.

       A tab widget provides a tab bar of tabs and a `page area' below (or above, see TabPosition) the tabs. Each tab is associated with a
       different widget (called a `page'). Only the current tab's page is shown in the page area; all the other tabs' pages are hidden. The user
       can show a different page by clicking on its tab or by pressing its Alt+letter accelerator if it has one.

       The normal way to use QTabWidget is to do the following in the constructor: <ol type=1>

       1      Create a QTabWidget.

       2      Create a QWidget for each of the pages in the tab dialog, insert children into it, set up geometry management for it and use
	      addTab() (or insertTab()) to set up a tab and keyboard accelerator for it.

       3      Connect to the signals and slots.

       The position of the tabs is set with setTabPosition(), their shape with setTabShape(), and their margin with setMargin().

       If you don't call addTab() and the QTabWidget is already visible, then the page you have created will not be visible. Don't confuse the
       object name you supply to the QWidget constructor and the tab label you supply to addTab(). addTab() takes a name which indicates an
       accelerator and is meaningful and descriptive to the user, whereas the widget name is used primarily for debugging.

       The signal currentChanged() is emitted when the user selects a page.

       The current page is available as an index position with currentPageIndex() or as a wiget pointer with currentPage(). You can retrieve a
       pointer to a page with a given index using page(), and can find the index position of a page with indexOf(). Use setCurrentPage() to show a
       particular page by index, or showPage() to show a page by widget pointer.

       You can change a tab's label and iconset using changeTab() or setTabLabel() and setTabIconSet(). A tab page can be removed with
       removePage().

       Each tab is either enabled or disabled at any given time (see setTabEnabled()). If a tab is enabled, the tab text is drawn normally and the
       user can select that tab. If it is disabled, the tab is drawn in a different way and the user cannot select that tab. Note that even if a
       tab is disabled, the page can still be visible, for example if all of the tabs happen to be disabled.

       Although tab widgets can be a very good way to split up a complex dialog, it's also very easy to get into a mess. See QTabDialog for some
       design hints. An alternative is to use a QWidgetStack for which you provide some means of navigating between pages, for example, a QToolBar
       or a QListBox.

       Most of the functionality in QTabWidget is provided by a QTabBar (at the top, providing the tabs) and a QWidgetStack (most of the area,
       organizing the individual pages).

   Member Type Documentation
QTabWidget::TabPosition
       This enum type defines where QTabWidget draws the tab row:

       QTabWidget::Top - above the pages

       QTabWidget::Bottom - below the pages

QTabWidget::TabShape
       This enum type defines the shape of the tabs:

       QTabWidget::Rounded - rounded look (normal)

       QTabWidget::Triangular - triangular look (very unusual, included for completeness)

MEMBER FUNCTION DOCUMENTATION

QTabWidget::QTabWidget ( QWidget * parent = 0, const char * name = 0, WFlags f = 0 )
       Constructs a tabbed widget called name with parent parent, and widget flags f.

void QTabWidget::addTab ( QWidget * child, const QString & label ) [virtual]
       Adds another tab and page to the tab view.

       The new page is child; the tab's label is label. Note the difference between the widget name (which you supply to widget constructors and
       to setTabEnabled(), for example) and the tab label. The name is internal to the program and invariant, whereas the label is shown on-screen
       and may vary according to language and other factors.

       If the tab's label contains an ampersand, the letter following the ampersand is used as an accelerator for the tab, e.g. if the label is
       "Bro&wse" then Alt+W becomes an accelerator which will move the focus to this tab.

       If you call addTab() after show() the screen will flicker and the user may be confused.

       Adding the same child twice will have undefined behavior.

       See also insertTab().

       Examples:

void QTabWidget::addTab ( QWidget * child, const QIconSet & iconset, const QString & label ) [virtual]
       This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

       Adds another tab and page to the tab view.

       This function is the same as addTab(), but with an additional iconset.

void QTabWidget::addTab ( QWidget * child, QTab * tab ) [virtual]
       This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

       This is a low-level function for adding tabs. It is useful if you are using setTabBar() to set a QTabBar subclass with an overridden
       QTabBar::paint() function for a subclass of QTab. The child is the new page and tab is the tab to put the child on.

void QTabWidget::changeTab ( QWidget * w, const QString & label )
       Defines a new label for page w's tab.

void QTabWidget::changeTab ( QWidget * w, const QIconSet & iconset, const QString & label )
       This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

       Defines a new iconset and a new label for page w's tab.

QWidget * QTabWidget::cornerWidget ( Qt::Corner corner = Qt::TopRight ) const
       Returns the widget shown in the corner of the tab widget or 0.

int QTabWidget::count () const
       Returns the number of tabs in the tab bar. See the "count" property for details.

void QTabWidget::currentChanged ( QWidget * ) [signal]
       This signal is emitted whenever the current page changes. The parameter is the new current page.

       See also currentPage(), showPage(), and tabLabel().

QWidget * QTabWidget::currentPage () const
       Returns a pointer to the page currently being displayed by the tab dialog. The tab dialog does its best to make sure that this value is
       never 0 (but if you try hard enough, it can be).

int QTabWidget::currentPageIndex () const
       Returns the index position of the current tab page. See the "currentPage" property for details.

int QTabWidget::indexOf ( QWidget * w ) const
       Returns the index position of page w, or -1 if the widget cannot be found.

void QTabWidget::insertTab ( QWidget * child, const QString & label, int index = -1 ) [virtual]
       Inserts another tab and page to the tab view.

       The new page is child; the tab's label is label. Note the difference between the widget name (which you supply to widget constructors and
       to setTabEnabled(), for example) and the tab label. The name is internal to the program and invariant, whereas the label is shown on-screen
       and may vary according to language and other factors.

       If the tab's label contains an ampersand, the letter following the ampersand is used as an accelerator for the tab, e.g. if the label is
       "Bro&wse" then Alt+W becomes an accelerator which will move the focus to this tab.

       If index is not specified, the tab is simply appended. Otherwise it is inserted at the specified position.

       If you call insertTab() after show(), the screen will flicker and the user may be confused.

       See also addTab().

void QTabWidget::insertTab ( QWidget * child, const QIconSet & iconset, const QString & label, int index = -1 ) [virtual]
       This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

       Inserts another tab and page to the tab view.

       This function is the same as insertTab(), but with an additional iconset.

void QTabWidget::insertTab ( QWidget * child, QTab * tab, int index = -1 ) [virtual]
       This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

       This is a lower-level method for inserting tabs, similar to the other insertTab() method. It is useful if you are using setTabBar() to set
       a QTabBar subclass with an overridden QTabBar::paint() function for a subclass of QTab. The child is the new page, tab is the tab to put
       the child on and index is the position in the tab bar that this page should occupy.

bool QTabWidget::isTabEnabled ( QWidget * w ) const
       Returns TRUE if the page w is enabled; otherwise returns FALSE.

       See also setTabEnabled() and QWidget::enabled.

QString QTabWidget::label ( int index ) const
       Returns the label of the tab at index position index or QString::null if the index is out of range.

int QTabWidget::margin () const
       Returns the margin in this tab widget. See the "margin" property for details.

QWidget * QTabWidget::page ( int index ) const
       Returns the tab page at index position index or 0 if the index is out of range.

void QTabWidget::removePage ( QWidget * w ) [virtual slot]
       Removes page w from this stack of widgets. Does not delete w.

       See also addTab(), showPage(), and QWidgetStack::removeWidget().

void QTabWidget::removeTabToolTip ( QWidget * w )
       Removes the tab tool tip for page w. If the page does not have a tip, nothing happens.

       See also setTabToolTip() and tabToolTip().

void QTabWidget::setCornerWidget ( QWidget * w, Qt::Corner corner = Qt::TopRight )
       Sets widget w to be the shown in the specified corner of the tab widget.

       Only the horizontal element of the corner will be used.

       See also cornerWidget() and tabPosition.

void QTabWidget::setCurrentPage ( int ) [slot]
       Sets the index position of the current tab page. See the "currentPage" property for details.

void QTabWidget::setMargin ( int )
       Sets the margin in this tab widget. See the "margin" property for details.

void QTabWidget::setTabBar ( QTabBar * tb ) [protected]
       Replaces the dialog's QTabBar heading with the tab bar tb. Note that this must be called before any tabs have been added, or the behavior
       is undefined.

       See also tabBar().

void QTabWidget::setTabEnabled ( QWidget * w, bool enable )
       If enable is TRUE, page w is enabled; otherwise page w is disabled. The page's tab is redrawn appropriately.

       QTabWidget uses QWidget::setEnabled() internally, rather than keeping a separate flag.

       Note that even a disabled tab/page may be visible. If the page is visible already, QTabWidget will not hide it; if all the pages are
       disabled, QTabWidget will show one of them.

       See also isTabEnabled() and QWidget::enabled.

void QTabWidget::setTabIconSet ( QWidget * w, const QIconSet & iconset )
       Sets the iconset for page w to iconset.

void QTabWidget::setTabLabel ( QWidget * w, const QString & l )
       Sets the tab label for page w to l

void QTabWidget::setTabPosition ( TabPosition )
       Sets the position of the tabs in this tab widget. See the "tabPosition" property for details.

void QTabWidget::setTabShape ( TabShape s )
       Sets the shape of the tabs in this tab widget to s. See the "tabShape" property for details.

void QTabWidget::setTabToolTip ( QWidget * w, const QString & tip )
       Sets the tab tool tip for page w to tip.

       See also removeTabToolTip() and tabToolTip().

void QTabWidget::showPage ( QWidget * w ) [virtual slot]
       Ensures that page w is shown. This is useful mainly for accelerators.

       Warning: Used carelessly, this function can easily surprise or confuse the user.

       See also QTabBar::currentTab.

QTabBar * QTabWidget::tabBar () const [protected]
       Returns the current QTabBar.

       See also setTabBar().

QIconSet QTabWidget::tabIconSet ( QWidget * w ) const
       Returns the iconset of page w or a null iconset if w is not a tab page or does not have an iconset.

QString QTabWidget::tabLabel ( QWidget * w ) const
       Returns the label text for the tab on page w.

TabPosition QTabWidget::tabPosition () const
       Returns the position of the tabs in this tab widget. See the "tabPosition" property for details.

TabShape QTabWidget::tabShape () const
       Returns the shape of the tabs in this tab widget. See the "tabShape" property for details.

QString QTabWidget::tabToolTip ( QWidget * w ) const
       Returns the tab tool tip for page w or QString::null if no tool tip has been set.

       See also setTabToolTip() and removeTabToolTip().
