NAME
       QFocusData - Maintains the list of widgets in the focus chain

SYNOPSIS
       #include <qfocusdata.h>

   Public Members
       QWidget * focusWidget () const
       QWidget * home ()
       QWidget * next ()
       QWidget * prev ()
       QWidget * first () const
       QWidget * last () const
       int count () const

DESCRIPTION
       The QFocusData class maintains the list of widgets in the focus chain.

       This read-only list always contains at least one widget (i.e. the top-
       level widget). It provides a simple cursor which can be reset to the
       current focus widget using home(), or moved to its neighboring widgets
       using next() and prev(). You can also retrieve the count() of the
       number of widgets in the list. The list is a loop, so if you keep
       iterating, for example using next(), you will never come to the end.

       Some widgets in the list may not accept focus. Widgets are added to the
       list as necessary, but not removed from it. This lets widgets change
       focus policy dynamically without disrupting the focus chain the user
       experiences. When a widget disables and re-enables tab focus, its
       position in the focus chain does not change.

       When reimplementing QWidget::focusNextPrevChild() to provide special
       focus flow, you will usually call QWidget::focusData() to retrieve the
       focus data stored at the top-level widget. A top-level widget's focus
       data contains the focus list for its hierarchy of widgets.

       The cursor may change at any time.

       This class is not thread-safe.

       See also QWidget::focusNextPrevChild(), QWidget::setTabOrder(),
       QWidget::focusPolicy, and Miscellaneous Classes.

MEMBER FUNCTION DOCUMENTATION
int QFocusData::count () const
       Returns the number of widgets in the focus chain.

QWidget * QFocusData::first () const
       Returns the first widget in the focus chain. The cursor is not
       modified.

QWidget * QFocusData::focusWidget () const
       Returns the widgets in the hierarchy that are in the focus chain.

QWidget * QFocusData::home ()
       Moves the cursor to the focusWidget() and returns that widget. You must
       call this before next() or prev() to iterate meaningfully.

QWidget * QFocusData::last () const
       Returns the last widget in the focus chain. The cursor is not modified.

QWidget * QFocusData::next ()
       Moves the cursor to the next widget in the focus chain. There is always
       a next widget because the list is a loop.

QWidget * QFocusData::prev ()
       Moves the cursor to the previous widget in the focus chain. There is
       always a previous widget because the list is a loop.
