virtual AIS_KindOfInteractive	Type () const
	Returns the kind of Interactive Object: More...

virtual Standard_Integer	Signature () const
	Specifies additional characteristics of Interactive Objects. A signature is, in fact, an index with integer values assigned different properties. This method is frequently used in conjuction with Type to give a particular type and signature to an Interactive Object. By default, the Interactive Object has a None type and a signature of 0. Among the datums, this signature is attributed to the shape The remaining datums have the following default signatures: More...

virtual Standard_Boolean	AcceptShapeDecomposition () const
	Informs the graphic context that the interactive Object may be decomposed into sub-shapes for dynamic selection. The most used Interactive Object is AIS_Shape. Activation methods for standard selection modes are proposed in the Interactive Context. These include selection by vertex or by edges. For datums with the same behavior as AIS_Shape, such as vetices and edges, we must redefine the virtual method so that AcceptShapeDecomposition returns false.

Standard_Integer	SelectionPriority () const
	Returns the selection priority setting. -1 indicates that there is none. You can modify the selection priority of an owner to make one entity more selectionable than another one. The default selection priority for an owner is 5, for example. To increase selection priority, choose a setting between 5 and 10. An entity with priority 7 will take priority over one with a setting of 6 if both objects are selected at the same time. You could give vertices priority 8, edges priority 7, faces priority 6, and shapes priority 5. If a vertex, an edge and a face are simultaneously detected during selection, only the vertex will then be highlighted. For trihedra, for example, the default priorities are the following four: More...

To do this, we use the following functions: More...

void	SetHilightMode (const Standard_Integer anIndex)
	Sets the highlight mode anIndex for the interactive object. If, for example, you want to systematically highlight the wireframe presentation of a shape - whether visualized in wireframe presentation or with shading - you set the highlight mode to 0. More...

Detailed Description

Interactive object for set of points. The presentation supports two display modes:

Points.
Bounding box for highlighting. Presentation provides selection by bouding box. Selection and consequently highlighting can disabled by setting default selection mode to -1. There will be no way to select object from interactive view. Any calls to AIS_InteractiveContext::AddOrRemoveSelected should be also prohibited, to avoid programmatic highlighting (workaround is setting non-supported hilight mode, e.g. 100);
