Member Function Documentation

virtual IVtk_SelectionModeList IVtkOCC_ShapePickerAlgo::GetSelectionModes ( const IVtk_IShape::Handle theShape) const
overridevirtual

Get activated selection modes for a shape.

Parameters
[in]theShapea shape with activated selection mode(s)
Returns
list of active selection modes

Implements IVtk_IShapePickerAlgo.

virtual int IVtkOCC_ShapePickerAlgo::NbPicked ( )
overridevirtual

Get number of picked entities.

Implements IVtk_IShapePickerAlgo.

virtual bool IVtkOCC_ShapePickerAlgo::Pick ( const double  theX,
const double  theY 
)
overridevirtual

Implements IVtk_IShapePickerAlgo.

virtual bool IVtkOCC_ShapePickerAlgo::Pick ( const double  theXMin,
const double  theYMin,
const double  theXMax,
const double  theYMax 
)
overridevirtual

Implements IVtk_IShapePickerAlgo.

virtual bool IVtkOCC_ShapePickerAlgo::Pick ( double **  thePolyLine,
const int  theNbPoints 
)
overridevirtual

Implements IVtk_IShapePickerAlgo.

virtual void IVtkOCC_ShapePickerAlgo::SetSelectionMode ( const IVtk_IShape::Handle theShape,
const IVtk_SelectionMode  theMode,
const bool  theIsTurnOn = true 
)
overridevirtual

Activates/deactivates the given selection mode for the shape. If mode == SM_None, the shape becomes non-selectable and is removed from the internal selection data.

Parameters
[in]theShapeShape for which the selection mode should be activated
[in]theModeSelection mode to be activated
[in]theIsTurnOnFlag to turn on/off the selection mode

Implements IVtk_IShapePickerAlgo.

virtual void IVtkOCC_ShapePickerAlgo::SetSelectionMode ( const IVtk_ShapePtrList theShapes,
const IVtk_SelectionMode  theMode,
const bool  theIsTurnOn = true 
)
overridevirtual

Activates/deactivates the given selection mode for the shape. If mode == SM_None, the shape becomes non-selectable and is removed from the internal selection data.

Parameters
[in]theShapesList of shapes for which the selection mode should be activated
[in]theModeSelection mode to be activated
[in]theIsTurnOnFlag to turn on/off the selection mode

Implements IVtk_IShapePickerAlgo.

virtual void IVtkOCC_ShapePickerAlgo::SetView ( const IVtk_IView::Handle theView)
overridevirtual

Sets the picker's view interface. The picker uses the view to obtain parameters of the 3D view projection.

Implements IVtk_IShapePickerAlgo.

virtual const IVtk_ShapeIdList& IVtkOCC_ShapePickerAlgo::ShapesPicked ( ) const
overridevirtual
Returns
the list of picked top-level shape IDs, in the order of increasing depth (the ID of the shape closest to the eye is the first in the list)

Implements IVtk_IShapePickerAlgo.

virtual void IVtkOCC_ShapePickerAlgo::SubShapesPicked ( const IVtk_IdType  theId,
IVtk_ShapeIdList theShapeList 
) const
overridevirtual
Parameters
[in]theIdTop-level shape ID
[out]theShapeListthe list of picked sub-shape IDs for the given top-level shape ID, in the order of increasing depth (the ID of the sub-shape closest to the eye is the first in the list)

Implements IVtk_IShapePickerAlgo.
