Member Function Documentation

◆ columnsAboutToBeInserted()

void QItemSelectionModelPrivate::columnsAboutToBeInserted	(	const QModelIndex &	parent,
		int	start,
		int	end )

Split selection ranges if columns are about to be inserted in the middle.

Definition at line 641 of file qitemselectionmodel.cpp.

◆ expandSelection()

QItemSelection QItemSelectionModelPrivate::expandSelection	(	const QItemSelection &	selection,
		QItemSelectionModel::SelectionFlags	command ) const

returns a QItemSelection where all ranges have been expanded to: Rows: left: 0 and right: columnCount()-1 Columns: top: 0 and bottom: rowCount()-1

◆ layoutAboutToBeChanged()

void QItemSelectionModelPrivate::layoutAboutToBeChanged	(	const QList< QPersistentModelIndex > &	parents,
		QAbstractItemModel::LayoutChangeHint	hint )

Split selection into individual (persistent) indexes. This is done in preparation for the layoutChanged() signal, where the indexes can be merged again.

Definition at line 880 of file qitemselectionmodel.cpp.

◆ layoutChanged()

void QItemSelectionModelPrivate::layoutChanged	(	const QList< QPersistentModelIndex > &	parents,
		QAbstractItemModel::LayoutChangeHint	hint )

Merge the selected indexes into selection ranges again.

Definition at line 1046 of file qitemselectionmodel.cpp.

◆ modelChanged()

void QItemSelectionModelPrivate::modelChanged ( QAbstractItemModel * mod )

inline

Definition at line 75 of file qitemselectionmodel_p.h.

◆ modelDestroyed()

void QItemSelectionModelPrivate::modelDestroyed ( )

Called when the used model gets destroyed.

It is impossible to have a correct implementation here. In the following situation, there are two contradicting rules:

QProperty<QAbstractItemModel *> leader(mymodel);
QItemSelectionModel myItemSelectionModel;
myItemSelectionModel.bindableModel().setBinding([&](){ return leader.value(); }
delete mymodel;
QAbstractItemModel *returnedModel = myItemSelectionModel.model();

What should returnedModel be in this situation?

Rules for bindable properties say that myItemSelectionModel.model() should return the same as leader.value(), namely the pointer to the now deleted model.

However, backward compatibility requires myItemSelectionModel.model() to return a nullptr, because that was done in the past after the model used was deleted.

We decide to break the new rule, imposed by bindable properties, and not break the old rule, because that may break existing code.
