Detailed Description

+ + +The TQFocusData 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 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 not thread-safe. +

Member Function Documentation

int TQFocusData::count () const +

+ +

Returns the number of widgets in the focus chain. + +

TQWidget * TQFocusData::first () const +

+Returns the first widget in the focus chain. +The cursor is not modified. + +

TQWidget * TQFocusData::focusWidget () const +

+ +

Returns the widgets in the hierarchy that are in the focus chain. + +

TQWidget * TQFocusData::home () +

+Moves the cursor to the focusWidget() and returns that widget. You +must call this before next() or prev() to iterate meaningfully. + +

TQWidget * TQFocusData::last () const +

+Returns the last widget in the focus chain. +The cursor is not modified. + +

TQWidget * TQFocusData::next () +

+Moves the cursor to the next widget in the focus chain. There is +always a next widget because the list is a loop. + +

TQWidget * TQFocusData::prev () +

+Moves the cursor to the previous widget in the focus chain. There +is always a previous widget because the list is a loop. + + +
