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 TQWidget::focusNextPrevChild() to provide - special focus flow, you will usually call TQWidget::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 \e not thread-safe. - - \sa TQWidget::focusNextPrevChild() TQWidget::setTabOrder() - TQWidget::setFocusPolicy() -*/ - -/*! - \fn TQWidget* TQFocusData::tqfocusWidget() const - - Returns the widgets in the hierarchy that are in the focus chain. -*/ - -/*! - \fn int TQFocusData::count() const - - Returns the number of widgets in the focus chain. -*/ - -/*! - Moves the cursor to the tqfocusWidget() and returns that widget. You - must call this before next() or prev() to iterate meaningfully. -*/ -TQWidget* TQFocusData::home() -{ - tqfocusWidgets.find(it.current()); - return tqfocusWidgets.current(); -} - -/*! - Moves the cursor to the next widget in the focus chain.
