Public Member Functions

Standard_EXPORT Select3D_SensitivePoint (const Handle(SelectBasics_EntityOwner)&OwnerId, const gp_Pnt &Point)
 Constructs a sensitive point object defined by the
owner OwnerId and the point Point.
.
Standard_EXPORT void Project (const Select3D_Projector &aProjector)
 Converts the stored 3D point into a 2D point according
to <aprojector> ; this method is called by the selection Manager.
.
Standard_EXPORT void Areas (SelectBasics_ListOfBox2d &aresult)
 stores in <aresult> the 2D sensitive box which represents
the point area in the selection process.

Standard_EXPORT Handle_Select3D_SensitiveEntity GetConnected (const TopLoc_Location &aLocation)
 Returns the sensitive entity found at the location aLocation.
You must redefine this function for any type of
sensitive entity which can accept another connected
sensitive entity.//can be connected to another sensitive entity.
.
Standard_EXPORT Standard_Boolean Matches (const Standard_Real X, const Standard_Real Y, const Standard_Real aTol, Standard_Real &DMin)
 returns true if the X,Y position matches the point
else gives the distance between them.

Standard_EXPORT Standard_Boolean Matches (const Standard_Real XMin, const Standard_Real YMin, const Standard_Real XMax, const Standard_Real YMax, const Standard_Real aTol)
 Matches the box defined by the coordinates Xmin,
Ymin, Xmax, Ymax with the entity found at that point
within the tolerance aTol.
Xmin, YMin define the minimum point in the lower left
hand corner of the box, and XMax, YMax define the
maximum point in the upper right hand corner of the box.
You must redefine this function for every inheriting entity.
You will have to call this framework inside the redefined function.
.
virtual Standard_EXPORT Standard_Boolean Matches (const TColgp_Array1OfPnt2d &Polyline, const Bnd_Box2d &aBox, const Standard_Real aTol)
 prevents from hiding virtual methods...

Standard_EXPORT Standard_Real ComputeDepth (const gp_Lin &EyeLine) const
 Returns the depth of this object on the line EyeLine.
EyeLine goes through the eye towards a point
defined by the coordinates X,Y in the function GetEyeLine.
//! gives an abcissa on <alin> .
<alin> represents the line going through
the eye towards an X,Y point on the screen. This Method
must return a mean Depth on this line.
.
Standard_EXPORT gp_Pnt Point () const
 Returns the point used at the time of construction.
.
virtual Standard_EXPORT void Dump (Standard_OStream &S, const Standard_Boolean FullDump=Standard_True) const
 2 options :
<fulldump> = False -> general information
<fulldump> = True -> whole informtion 3D +2d ...
