Standard_Boolean NeedsConversion () const
 Returns true if this framework needs conversion.

Standard_Boolean Is3D () const
 Returns true if this framework provides 3D information.
More...
 
virtual Standard_Integer MaxBoxes () const
 Returns the max number of sensitive areas returned
by this class is 1 by default.
Else on must redefine this method.

virtual
Handle_Select3D_SensitiveEntity 
GetConnected (const TopLoc_Location &aLocation)
 
 Originally this method intended to return sensitive <br>

entity with new location aLocation, but currently sensitive
entities do not hold a location, instead HasLocation() and
Location() methods call corresponding entity owner's methods.
Thus all entities returned by GetConnected() share the same
location propagated from corresponding selectable object.
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.

virtual 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, <br>

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_Boolean Matches (const SelectBasics_PickArgs &thePickArgs, Standard_Real &theMatchDMin, Standard_Real &theMatchDepth)=0
 
 Checks whether the sensitive entity matches the picking detection <br>

area (close to the picking line). This method takes into account depth
limits produced by abstract view: far/near planes, clippings.
Please port existing implementations of your picking detection, which
were done at Matches (X, Y, Tol, DMin) method to this one, introducing
the depth checks. Please note that the previous method is suppressed
and the virtual implementations are not used by OCC selection framework.
The porting procedure for simple sensitives (or if you are not interested
in implementing full scale depth checks) can be simplified to writing the
following code snippet:

void SetSensitivityFactor (const Standard_ShortReal aFactor)
 
Standard_ShortReal SensitivityFactor () const
 allows a better sensitivity for
a specific entity in selection algorithms
useful for small sized entities.
