Function Documentation

indexesFromRange()

template<typename ModelIndexContainer>

static void indexesFromRange ( const QItemSelectionRange & range, ModelIndexContainer & result )

static

Definition at line 310 of file qitemselectionmodel.cpp.

isSelectableAndEnabled()

static bool isSelectableAndEnabled ( Qt::ItemFlags flags )

inlinestatic

Definition at line 304 of file qitemselectionmodel.cpp.

mergeIndexes()

static QItemSelection mergeIndexes ( const QList< QPersistentModelIndex > & indexes )

static

Merges indexes into an item selection made up of ranges. Assumes that the indexes are sorted.

Definition at line 963 of file qitemselectionmodel.cpp.

mergeRowLengths()

static QItemSelection mergeRowLengths ( const QList< std::pair< QPersistentModelIndex, uint > > & rowLengths )

static

Definition at line 923 of file qitemselectionmodel.cpp.

operator<<()

QDebug operator<<	(	QDebug	dbg,
		const QItemSelectionRange &	range )

Definition at line 2033 of file qitemselectionmodel.cpp.

qHash()

size_t qHash ( const RowOrColumnDefinition & key, size_t seed = 0 )

noexcept

Definition at line 1807 of file qitemselectionmodel.cpp.

References RowOrColumnDefinition::rowOrColumn.

qSelectionIndexes()

template<typename ModelIndexContainer>

static ModelIndexContainer qSelectionIndexes ( const QItemSelection & selection )

static

Definition at line 328 of file qitemselectionmodel.cpp.

qSelectionPersistentRowLengths()

static QList< std::pair< QPersistentModelIndex, uint > > qSelectionPersistentRowLengths ( const QItemSelection & sel )

static

Definition at line 478 of file qitemselectionmodel.cpp.

qt_PersistentModelIndexLessThan()

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.

Definition at line 1034 of file qitemselectionmodel.cpp.

rowLengthsFromRange()

static void rowLengthsFromRange ( const QItemSelectionRange & range, QList< std::pair< QPersistentModelIndex, uint > > & result )

static

Definition at line 288 of file qitemselectionmodel.cpp.

selectionIsEmpty()

static bool selectionIsEmpty ( const QItemSelection & selection )

inlinestatic

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