	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.

void	RecomputePrimitives ()
	Re-computes the sensitive primitives for all modes. IMPORTANT: Do not use this method to update selection primitives except implementing custom selection manager! This method does not take into account necessary BVH updates, but may invalidate the pointers it refers to. TO UPDATE SELECTION properly from outside classes, use method UpdateSelection.

Detailed Description

A framework to supply the structure of the object to be selected. At the first pick, this structure is created by calling the appropriate algorithm and retaining this framework for further picking. This abstract framework is inherited in Application Interactive Services (AIS), notably in AIS_InteractiveObject. Consequently, 3D selection should be handled by the relevant daughter classes and their member functions in AIS. This is particularly true in the creation of new interactive objects.

Key interface methods to be implemented by every Selectable Object:

Presentable Object (PrsMgr_PresentableObject) Consider defining an enumeration of supported Display Mode indexes for particular Interactive Object or class of Interactive Objects.
- AcceptDisplayMode() accepting display modes implemented by this object;
- Compute() computing presentation for the given display mode index;
Selectable Object (SelectMgr_SelectableObject) Consider defining an enumeration of supported Selection Mode indexes for particular Interactive Object or class of Interactive Objects.
- ComputeSelection() computing selectable entities for the given selection mode index.

Handle< Prs3d_Presentation > SelectMgr_SelectableObject::GetHilightPresentation ( const Handle< PrsMgr_PresentationManager > & thePrsMgr )

Creates or returns existing presentation for highlighting detected object.

Parameters

thePrsMgr presentation manager to create new presentation

Returns: existing or newly created presentation (when thePrsMgr is not NULL)

◆ GetSelectPresentation()

Handle< Prs3d_Presentation > SelectMgr_SelectableObject::GetSelectPresentation ( const Handle< PrsMgr_PresentationManager > & thePrsMgr )

Creates or returns existing presentation for highlighting selected object.

Parameters

thePrsMgr presentation manager to create new presentation

Returns: existing or newly created presentation (when thePrsMgr is not NULL)

◆ GlobalSelectionMode()

Standard_Integer SelectMgr_SelectableObject::GlobalSelectionMode ( ) const

inline

Returns the mode for selection of object as a whole; 0 by default.

◆ GlobalSelOwner()

virtual Handle< SelectMgr_EntityOwner > SelectMgr_SelectableObject::GlobalSelOwner ( ) const

virtual

Returns the owner of mode for selection of object as a whole.

Reimplemented in AIS_MultipleConnectedInteractive, and AIS_ViewCube.

◆ HasSelection()

Standard_Boolean SelectMgr_SelectableObject::HasSelection ( const Standard_Integer theMode ) const

inline

Returns true if a selection corresponding to the selection mode theMode was computed for this object.

◆ HilightOwnerWithColor()

virtual void SelectMgr_SelectableObject::HilightOwnerWithColor	(	const Handle< PrsMgr_PresentationManager > &	thePM,
		const Handle< Prs3d_Drawer > &	theStyle,
		const Handle< SelectMgr_EntityOwner > &	theOwner
	)

virtual

Method which hilight an owner belonging to this selectable object ( for fast presentation draw )

Reimplemented in MeshVS_Mesh, AIS_Manipulator, AIS_Trihedron, and AIS_ViewCube.

◆ HilightSelected()

virtual void SelectMgr_SelectableObject::HilightSelected	(	const Handle< PrsMgr_PresentationManager > &	thePrsMgr,
		const SelectMgr_SequenceOfOwner &	theSeq
	)

virtual

Method which draws selected owners ( for fast presentation draw )

Reimplemented in AIS_Trihedron, AIS_Manipulator, AIS_ViewCube, and MeshVS_Mesh.

◆ IsAutoHilight()

virtual Standard_Boolean SelectMgr_SelectableObject::IsAutoHilight ( ) const

inlinevirtual

If returns True, the old mechanism for highlighting selected objects is used (HilightSelected Method may be empty). If returns False, the HilightSelected method will be fully responsible for highlighting selected entity owners belonging to this selectable object.

Reimplemented in AIS_Manipulator, and AIS_ViewCube.

◆ RecomputePrimitives() [1/2]

void SelectMgr_SelectableObject::RecomputePrimitives ( )

Re-computes the sensitive primitives for all modes. IMPORTANT: Do not use this method to update selection primitives except implementing custom selection manager! This method does not take into account necessary BVH updates, but may invalidate the pointers it refers to. TO UPDATE SELECTION properly from outside classes, use method UpdateSelection.

◆ RecomputePrimitives() [2/2]

void SelectMgr_SelectableObject::RecomputePrimitives ( const Standard_Integer theMode )

Re-computes the sensitive primitives which correspond to the <theMode>th selection mode. IMPORTANT: Do not use this method to update selection primitives except implementing custom selection manager! selection manager! This method does not take into account necessary BVH updates, but may invalidate the pointers it refers to. TO UPDATE SELECTION properly from outside classes, use method UpdateSelection.

◆ ResetTransformation()

void SelectMgr_SelectableObject::ResetTransformation ( )

overridevirtual

resets local transformation to identity.

Reimplemented from PrsMgr_PresentableObject.

◆ Selection()

const Handle< SelectMgr_Selection > & SelectMgr_SelectableObject::Selection ( const Standard_Integer theMode ) const

Returns the selection having specified selection mode or NULL.

◆ Selections()

const SelectMgr_SequenceOfSelection & SelectMgr_SelectableObject::Selections ( ) const

inline

Return the sequence of selections.

◆ SetAssemblyOwner()

void SelectMgr_SelectableObject::SetAssemblyOwner	(	const Handle< SelectMgr_EntityOwner > &	theOwner,
		const Standard_Integer	theMode = `-1`
	)

Sets common entity owner for assembly sensitive object entities.

◆ SetAutoHilight()

virtual void SelectMgr_SelectableObject::SetAutoHilight ( const Standard_Boolean theAutoHilight )

inlinevirtual

Set AutoHilight property to true or false.

◆ setGlobalSelMode()

void SelectMgr_SelectableObject::setGlobalSelMode ( const Standard_Integer theMode )

inlineprotected

Override global selection mode.

◆ SetZLayer()

virtual void SelectMgr_SelectableObject::SetZLayer ( const Graphic3d_ZLayerId theLayerId )

overridevirtual

Set Z layer ID and update all presentations of the selectable object. The layers mechanism allows drawing objects in higher layers in overlay of objects in lower layers.

Reimplemented from PrsMgr_PresentableObject.

◆ UpdateClipping()

virtual void SelectMgr_SelectableObject::UpdateClipping ( )

overrideprotectedvirtual

Update clipping planes state.

Reimplemented from PrsMgr_PresentableObject.

◆ updateSelection()

virtual void SelectMgr_SelectableObject::updateSelection ( const Standard_Integer theMode )

protectedvirtual

Sets update status FULL to selections of the object. Must be used as the only method of UpdateSelection from outer classes to prevent BVH structures from being outdated.

◆ UpdateSelection()

void SelectMgr_SelectableObject::UpdateSelection ( const Standard_Integer theMode = -1 )

inline

Sets update status FULL to selections of the object. Must be used as the only method of UpdateSelection from outer classes to prevent BVH structures from being outdated.

◆ UpdateTransformation()

virtual void SelectMgr_SelectableObject::UpdateTransformation ( )

overridevirtual

Recomputes the location of the selection aSelection.

Reimplemented from PrsMgr_PresentableObject.

◆ UpdateTransformations()

virtual void SelectMgr_SelectableObject::UpdateTransformations ( const Handle< SelectMgr_Selection > & aSelection )

virtual

Updates locations in all sensitive entities from <aSelection> and in corresponding entity owners.
