Represents the state of a given selection mode for a
Selectable Object. Contains all the sensitive entities available for this mode.
An interactive object can have an indefinite number of
modes of selection, each representing a
"decomposition" into sensitive primitives; each
primitive has an Owner (SelectMgr_EntityOwner)
which allows us to identify the exact entity which has
been detected. Each Selection mode is identified by
an index. The set of sensitive primitives which
correspond to a given mode is stocked in a
SelectMgr_Selection object. By Convention, the
default selection mode which allows us to grasp the
Interactive object in its entirety will be mode 0.

| SelectMgr_Selection (const Standard_Integer IdMode=0) |
| Constructs a selection object defined by the selection mode IdMode.
The default setting 0 is the selection mode for a shape in its entirety.
|
void | Add (const Handle< SelectBasics_SensitiveEntity > &aprimitive) |
| Adds the sensitive primitive aprimitive to the list of
stored entities in this object.
Raises NullObject if the primitive is a null handle.
|
void | Clear () |
| empties the selection from all the stored entities
|
Standard_Boolean | IsEmpty () const |
| returns true if no sensitive entity is stored.
|
Standard_Integer | Mode () const |
| returns the selection mode represented by this selection
|
void | Init () |
| Begins an iteration scanning for sensitive primitives.
|
Standard_Boolean | More () const |
| Continues the iteration scanning for sensitive
primitives with the mode defined in this framework.
|
void | Next () |
| Returns the next sensitive primitive found in the
iteration. This is a scan for entities with the mode
defined in this framework.
|
const
Handle_SelectBasics_SensitiveEntity & | Sensitive () const |
| Returns any sensitive primitive in this framework.
|
SelectMgr_TypeOfUpdate | UpdateStatus () const |
| Returns the flag UpdateFlag.
This flage gives the update status of this framework
in a ViewerSelector object:

void | UpdateStatus (const SelectMgr_TypeOfUpdate UpdateFlag) |
Detailed Description
- mode 0 : selection of a trihedron
- mode 1 : selection of the origin of the trihedron
- mode 2 : selection of the axes
- mode 3 : selection of the planes XOY, YOZ, XOZ
when you activate one of modes 1 2 3 4 , you pick AIS objects of type:
- AIS_Point
- AIS_Axis (and information on the type of axis)
- AIS_Plane (and information on the type of plane).
AIS_PlaneTrihedron offers 3 selection modes:
- mode 0 : selection of the whole trihedron
- mode 1 : selection of the origin of the trihedron
- mode 2 : selection of the axes - same remarks as for the Trihedron.
AIS_Shape : 7 maximum selection modes, depending
on the complexity of the shape :
- mode 0 : selection of the AIS_Shape
- mode 1 : selection of the vertices
- mode 2 : selection of the edges
- mode 3 : selection of the wires
- mode 4 : selection of the faces
- mode 5 : selection of the shells
- mode 6 : selection of the constituent solids.
