Constructor & Destructor Documentation

◆ vtkQtTreeModelAdapter()

Member Function Documentation

◆ SetVTKDataObject()

void vtkQtTreeModelAdapter::SetVTKDataObject ( vtkDataObject data)
overridevirtual

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

Implements vtkQtAbstractModelAdapter.

◆ GetVTKDataObject()

vtkDataObject* vtkQtTreeModelAdapter::GetVTKDataObject ( ) const
overridevirtual

◆ GetVTKDataObjectMTime()

vtkMTimeType 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 adapter by call SetVTKDataObject again. :)

◆ QModelIndexListToVTKIndexSelection()

vtkSelection* vtkQtTreeModelAdapter::QModelIndexListToVTKIndexSelection ( const QModelIndexList  qmil) const
overridevirtual

Selection conversion from VTK land to Qt land.

Implements vtkQtAbstractModelAdapter.

◆ VTKIndexSelectionToQItemSelection()

QItemSelection vtkQtTreeModelAdapter::VTKIndexSelectionToQItemSelection ( vtkSelection vtksel) const
overridevirtual

◆ SetKeyColumnName()

overridevirtual

◆ SetColorColumnName()

void vtkQtTreeModelAdapter::SetColorColumnName ( const char *  name)
overridevirtual

◆ setTree()

void vtkQtTreeModelAdapter::setTree ( vtkTree t)

Set up the model based on the current tree.

◆ tree()

◆ index()

QModelIndex vtkQtTreeModelAdapter::index ( int  row,

◆ columnCount()

int vtkQtTreeModelAdapter::columnCount ( const QModelIndex &  parent = QModelIndex()) const
override

◆ supportedDragActions()

Qt::DropActions vtkQtTreeModelAdapter::supportedDragActions ( ) const
override

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.
