	)

Picks the sensitive entity according to the minimum and maximum pixel values <theXPMin>, <theYPMin>, <theXPMax> and <theYPMax> defining a 2D area for selection in the 3D view aView.

void StdSelect_ViewerSelector3d::Pick	(	const TColgp_Array1OfPnt2d &	thePolyline,
		const Handle< V3d_View > &	theView
	)

pick action - input pixel values for polyline selection for selection.

Standard_Real StdSelect_ViewerSelector3d::PixelTolerance ( ) const

Returns the pixel tolerance.

void StdSelect_ViewerSelector3d::ResetSelectionActivationStatus ( )

Marks all sensitive entities, stored in viewer selector, as inactive for selection.

void StdSelect_ViewerSelector3d::SetClipping ( const Graphic3d_SequenceOfHClipPlane & thePlanes )

protected

Set view clipping for the selector.

Parameters

thePlanes [in] the view planes.

void StdSelect_ViewerSelector3d::SetPixelTolerance ( const Standard_Real theTolerance )

Sets the pixel tolerance <theTolerance>.
