fixup()

void QQuickFlickablePrivate::fixup ( AxisData & data, qreal minExtent, qreal maxExtent )

virtual

This function should be called after the contentItem has been moved, either programmatically, or by the timeline (as a result of a flick). It ensures that the contentItem will be moved back into bounds, in case it was flicked outside of the visible area.

The positional adjustment will usually be animated by the timeline, unless the fixupMode is set to Immediate.

Reimplemented in QQuickGridViewPrivate, QQuickGridViewPrivate, QQuickListViewPrivate, QQuickListViewPrivate, and QQuickTableViewPrivate.
