Detailed Description

Selects the parents of selected items to create breadcrumbs.

For example, if the tree is

    - A
    - B
    - - C
    - - D
    - - - E
    - - - - F
  

and E is selected, the selection can contain

    - B
    - D
  

or

    - B
    - D
    - E
  

if isActualSelectionIncluded is true.

The depth of the selection may also be set. For example if the breadcrumbLength is 1:

    - D
    - E
  

And if breadcrumbLength is 2:

    - B
    - D
    - E
  

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.
