       QFocusData - Maintains the list of widgets in the focus chain

       #include <qfocusdata.h>

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

       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

       The cursor may change at any time.

       This class is not thread-safe.

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

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.
