/**
* @class KCheckableProxyModel kcheckableproxymodel.h KCheckableProxyModel
*
* @brief Adds a checkable capability to a source model
*
* Items is standard Qt views such as QTreeView and QListView can have a
* checkable capability and draw checkboxes. Adding such a capability
* requires specific implementations of the data() and flags() virtual methods.
* This class implements those methods generically so that it is not necessary to
* implement them in your model.
*
* This can be combined with a KSelectionProxyModel showing the items currently selected
*
* @code
*
* QItemSelectionModel *checkModel = new QItemSelectionModel(rootModel, this);
* KCheckableProxyModel *checkable = new KCheckableProxyModel(this);
* checkable->setSourceModel(rootModel);
* checkable->setSelectionModel(checkModel);
*
* QTreeView *tree1 = new QTreeView(vSplitter);
* tree1->setModel(checkable);
* tree1->expandAll();
*
* KSelectionProxyModel *selectionProxy = new KSelectionProxyModel(checkModel, this);
* selectionProxy->setFilterBehavior(KSelectionProxyModel::ExactSelection);
* selectionProxy->setSourceModel(rootModel);
*
* QTreeView *tree2 = new QTreeView(vSplitter);
* tree2->setModel(selectionProxy);
* @endcode
