Dear MITK users,
as a consequence of bug 17534 [1] we have implemented some changes to the Mime
types used for communicating TreeItem and DataNode pointer lists via Qt Drag
and Drop. These changes will be part of the next release:
The MIME types "application/x-mitk-datanodes" and
"application/x-qabstractitemmodeldatalist" have been deprecated. They are
currently still supported for backwards compatibility but this will probably
change after a few releases
You can instead use QmitkMimeTypes::DataNodePtrs and
QmitkMimeTypes::DataStorageTreeItemPtrs respectively, which are defined in the
new QmitkMimeTypes class
Instead of being stored as a comma separated list of pointers, they are now
streamed into and out of a byte array. This should eliminate 32/64 bit issues
due to casting between different data types.
We have implemented the following functions for your ease of access:
QList<mitk::DataNode *> QmitkMimeTypes::ToDataNodePtrList(const QByteArray &ba)
QList<mitk::DataNode *> QmitkMimeTypes::ToDataNodePtrList(const QMimeData
*mimeData)
QList<QmitkDataStorageTreeModel::TreeItem *>
QmitkDataStorageTreeModel::ToTreeItemPtrList(const QMimeData* mimeData)
QList<QmitkDataStorageTreeModel::TreeItem *>
QmitkDataStorageTreeModel::ToTreeItemPtrList(const QByteArray& ba)
You can take a look at these changes in the corresponding branch [2]. Please
let us know if you are relying on some properties of the old MIME types which
are not covered by the new system.
Best,
Caspar
