vtkActorCollection* IVtkTools_ShapePicker::GetPickedActors ( bool theIsAll = false ) const

Access to the list of actors picked.

Parameters

[in] all Controls if all selected actors or just the only top one is returned, has no effect during area selection.

Returns: List of actors IDs

IVtk_ShapeIdList IVtkTools_ShapePicker::GetPickedShapesIds ( bool theIsAll = false ) const

Access to the list of top-level shapes picked. If all argument is true, the picker returns the list of all OccShape objects found by the picking algorithm. e.g. all shapes under the mouse cursor. Otherwise, ID of the shape closest to the eye is returned.

Parameters

[in] all Controls if all selected shapes or just the only top one is returned, has no effect during area selection.

Returns: List of top-level shape IDs

IVtk_ShapeIdList IVtkTools_ShapePicker::GetPickedSubShapesIds	(	const IVtk_IdType	theId,
		bool	theIsAll = `false`

Access to the list of sub-shapes ids picked.

Parameters

[in]	id	top-level shape ID
[in]	all	Controls if all selected sub-shapes or just the only top one is returned, has no effect during area selection.

Returns: List of sub-shapes IDs

IVtk_SelectionModeList IVtkTools_ShapePicker::GetSelectionModes ( const IVtk_IShape::Handle & theShape ) const

Get activated selection modes for a shape.

Parameters

Returns: list of active selection modes

IVtk_SelectionModeList IVtkTools_ShapePicker::GetSelectionModes ( vtkActor * theShapeActor ) const

Get activated selection modes for a shape actor.

Parameters
