This class allows to create owners to all elements or nodes, both hidden and shown, but these owners user cannot select "by hands" in viewer. They means for internal application tasks, for example, receiving all owners, both for hidden and shown entities. More...

virtual Standard_Boolean | Matches (const SelectBasics_PickArgs &thePickArgs, Standard_Real &theMatchDMin, Standard_Real &theMatchDepth) |
Checks whether the sensitive entity matches the picking detection 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: More... | |
virtual Standard_Boolean | Matches (const Standard_Real XMin, const Standard_Real YMin, const Standard_Real XMax, const Standard_Real YMax, const Standard_Real aTol) |
returns True if the box (Xmin,YMin)---—(Xmax,Ymax) contains the SensitiveEntity. Necessary for selection using elastic boxes,or segments. More... | |

theMatchDMin | [out] the minimum distance on xy plane from point of picking to center of gravity of the detected sub-part of sensitive entity or the whole sensitive (e.g. used for resolving selection of coinciding circles, selection will be set to the one whose center is closest to the picking point). |
theMatchDepth | [out] the minimum detected depth: depth of the closest detected sub-part of sensitive entity (or the whole sensitive). |
