◆ 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

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

Implements vtkQtAbstractModelAdapter.

◆ 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. :)
