Detailed Description
KBreadcrumbSelectionModel kbreadcrumbselectionmodel.h
Selects the parents of selected items to create breadcrumbs
For example, if the tree is @verbatim - A - B - - C - - D - - - E - - - - F @endverbatim
and E is selected, the selection can contain
@verbatim - B - D @endverbatim
or
@verbatim - B - D - E @endverbatim
if isActualSelectionIncluded is true.
The depth of the selection may also be set. For example if the breadcrumbLength is 1:
@verbatim - D - E @endverbatim
And if breadcrumbLength is 2:
@verbatim - B - D - E @endverbatim
A KBreadcrumbsProxyModel with a breadcrumbLength of 0 and including the actual selection is the same as a KSelectionProxyModel in the KSelectionProxyModel.ExactSelection configuration.
view1->setModel(rootModel); QItemSelectionModel *breadcrumbSelectionModel = new QItemSelectionModel(rootModel, this); KBreadcrumbSelectionModel *breadcrumbProxySelector = new KBreadcrumbSelectionModel(breadcrumbSelectionModel, rootModel, this); view1->setSelectionModel(breadcrumbProxySelector); KSelectionProxyModel *breadcrumbSelectionProxyModel = new KSelectionProxyModel( breadcrumbSelectionModel, this); breadcrumbSelectionProxyModel->setSourceModel( rootModel ); breadcrumbSelectionProxyModel->setFilterBehavior( KSelectionProxyModel.ExactSelection ); view2->setModel(breadcrumbSelectionProxyModel);

"KBreadcrumbSelectionModel in several configurations"
This can work in two directions. One option is for a single selection in the KBreadcrumbSelectionModel to invoke the breadcrumb selection in its constructor argument.
The other is for a selection in the itemselectionmodel in the constructor argument to cause a breadcrumb selection in this.
