Detailed Description

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 - the focus data for that hierarchy of widgets.

See also: QWidget::focusNextPrevChild().

Member Function Documentation

int QFocusData::count () const

Returns a count of the number of widgets in the hierarchy which accept focus.

QWidget* QFocusData::focusWidget () const

Returns the widgets in the hierarchy which currently has focus.

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::next ()

Moves the cursor to the right. Note that the focus widgets are a loop of widgets. If you keep calling next(), it will loop, without ever returning 0.

QWidget* QFocusData::prev ()

Moves the cursor to the left. Note that the focus widgets are a loop of widgets. If you keep calling prev(), it will loop, without ever returning 0.
