Detailed Description

Makes it possible to share a selection in multiple views which do not have the same source model.

Although multiple views can share the same QItemSelectionModel, the views then need to have the same source model.

If there is a proxy model between the model and one of the views, or different proxy models in each, this class makes it possible to share the selection between the views.

kproxyitemselectionmodel-simple.png
Sharing a QItemSelectionModel between views on the same model is trivial
kproxyitemselectionmodel-error.png
If a proxy model is used, it is no longer possible to share the QItemSelectionModel directly
kproxyitemselectionmodel-solution.png
A KLinkItemSelectionModel can be used to map the selection through the proxy model
QAbstractItemModel *model = getModel();
proxy->setSourceModel(model);
QTreeView *view1 = new QTreeView(splitter);
view1->setModel(model);
KLinkItemSelectionModel *view2SelectionModel = new KLinkItemSelectionModel( proxy, view1->selectionModel());
QTreeView *view2 = new QTreeView(splitter);
// Note that the QAbstractItemModel passed to KLinkItemSelectionModel must be the same as what is used in the view
view2->setModel(proxy);
view2->setSelectionModel( view2SelectionModel );
kproxyitemselectionmodel-complex.png
Arbitrarily complex proxy configurations on the same root model can be used
QAbstractItemModel *model = getModel();
proxy1->setSourceModel(model);
proxy2->setSourceModel(proxy1);
proxy3->setSourceModel(proxy2);
QTreeView *view1 = new QTreeView(splitter);
view1->setModel(proxy3);
proxy4->setSourceModel(model);
proxy5->setSourceModel(proxy4);
KLinkItemSelectionModel *view2SelectionModel = new KLinkItemSelectionModel( proxy5, view1->selectionModel());
QTreeView *view2 = new QTreeView(splitter);
// Note that the QAbstractItemModel passed to KLinkItemSelectionModel must be the same as what is used in the view
view2->setModel(proxy5);
view2->setSelectionModel( view2SelectionModel );
