Detailed Description

Adapts a tree to a Qt item model.

vtkQtTreeModelAdapter is a QAbstractItemModel with a vtkTree as its underlying data model.

Member Function Documentation

virtual void vtkQtTreeModelAdapter::SetVTKDataObject ( vtkDataObject * data ) [virtual]

Set/Get the VTK data object as input to this adapter

Implements vtkQtAbstractModelAdapter.

virtual vtkDataObject* vtkQtTreeModelAdapter::GetVTKDataObject ( ) const [virtual]

Set/Get the VTK data object as input to this adapter

Implements vtkQtAbstractModelAdapter.

unsigned long vtkQtTreeModelAdapter::GetVTKDataObjectMTime ( ) const

Get the stored VTK data object modification time of when the adaption to a Qt model was done. This is in general not the same this as the data objects modification time. It is the mod time of the object when it was placed into the Qt model adapter. You can use this mtime as part of the checking to see whether you need to update the the adapter by call SetVTKDataObject again. :)

virtual vtkSelection* vtkQtTreeModelAdapter::QModelIndexListToVTKIndexSelection ( const QModelIndexList qmil ) const [virtual]

Selection conversion from VTK land to Qt land

Implements vtkQtAbstractModelAdapter.

virtual QItemSelection vtkQtTreeModelAdapter::VTKIndexSelectionToQItemSelection ( vtkSelection * vtksel ) const [virtual]

Selection conversion from VTK land to Qt land

Implements vtkQtAbstractModelAdapter.

virtual void vtkQtTreeModelAdapter::SetKeyColumnName ( const char * name ) [virtual]

Set/Get the key column. The key column is used as the row headers in a table view, and as the first column in a tree view. Set to -1 for no key column. The default is no key column.

Implements vtkQtAbstractModelAdapter.

virtual void vtkQtTreeModelAdapter::SetColorColumnName ( const char * name ) [virtual]

Set/Get the column storing the rgba color values for each row. The color column is used as the row headers in a table view, and as the first column in a tree view. Set to -1 for no key column. The default is no key column.

Implements vtkQtAbstractModelAdapter.

void vtkQtTreeModelAdapter::setTree ( vtkTree * t )

Set up the model based on the current tree.

vtkTree* vtkQtTreeModelAdapter::tree ( ) const [inline]

Set up the model based on the current tree.

Qt::DropActions vtkQtTreeModelAdapter::supportedDragActions ( ) const

If drag/drop is enabled in the view, the model will package up the current pedigreeid vtkSelection into a QMimeData when items are dragged. Currently only leaves of the tree can be dragged.

virtual QMimeData* vtkQtTreeModelAdapter::mimeData ( const QModelIndexList & indexes ) const [virtual]

If drag/drop is enabled in the view, the model will package up the current pedigreeid vtkSelection into a QMimeData when items are dragged. Currently only leaves of the tree can be dragged.

virtual QStringList vtkQtTreeModelAdapter::mimeTypes ( ) const [virtual]

If drag/drop is enabled in the view, the model will package up the current pedigreeid vtkSelection into a QMimeData when items are dragged. Currently only leaves of the tree can be dragged.
