static bool qt_PersistentModelIndexLessThan ( const QPersistentModelIndex & i1, const QPersistentModelIndex & i2 )

static

Sort predicate function for QItemSelectionModelPrivate::layoutChanged(), sorting by parent first in addition to operator<(). This is to prevent fragmentation of the selection by grouping indexes with the same row, column of different parents next to each other, which may happen when a selection spans sub-trees.

selectionIsEmpty()

static bool selectionIsEmpty ( const QItemSelection & selection )

Check whether the selection is empty. In contrast to selection.isEmpty(), this takes into account whether items are enabled and whether they are selectable.
