class AISPresentation from TPrsStd inherits Attribute from TDF
---Purpose: An attribute to associate an
-- AIS_InteractiveObject to a label in an AIS viewer.
-- This attribute works in collaboration with TPrsStd_AISViewer.
-- Note that all the Set... and Unset... attribute
-- methods as well as the query methods for
-- visualization attributes and the HasOwn... test
-- methods are shortcuts to the respective
-- AIS_InteractiveObject settings.

Drawer from AIS
is
GetID (myclass) returns GUID from Standard;
---Purpose: Returns the GUID for TPrsStd_AISPresentation attributes.
---C++: return const &
Set (myclass; L : Label from TDF; driver : GUID from Standard)
---Purpose: Creates or retrieves the presentation attribute on
-- the label L, and sets the GUID driver.
returns AISPresentation from TPrsStd;
Unset (myclass; L : Label from TDF);
---Purpose: Delete (if exist) the presentation attribute associated to the label <L>.
Set (myclass; master : Attribute from TDF)
---Purpose: Creates or retrieves the AISPresentation
-- attribute attached to master.
-- The GUID of the driver will be the GUID of master.
-- master is the attribute you want to display.
returns AISPresentation from TPrsStd;
---Category: Presentation attribute implementation
-- ======================================
Create returns mutable AISPresentation from TPrsStd;
SetDisplayed(me : mutable; B : Boolean from Standard);
Display (me : mutable; update : Boolean from Standard = Standard_False);
---Purpose: Display presentation of object in AIS viewer.
-- If <update> = True then AISObject is recomputed and all
-- the visualization settings are applied
Erase (me : mutable; remove : Boolean from Standard = Standard_False);
---Purpose: Removes the presentation of this AIS
-- presentation attribute from the TPrsStd_AISViewer.
-- If remove is true, this AIS presentation attribute
-- is removed from the interactive context.
Update (me : mutable);
---Purpose: Recompute presentation of object and apply the visualization settings
GetDriverGUID (me) returns GUID from Standard;
SetDriverGUID (me: mutable ; guid : GUID from Standard);
IsDisplayed (me)
returns Boolean from Standard;
---Purpose:
-- Returns true if this AIS presentation attribute is displayed.
GetAIS (me) returns InteractiveObject from AIS;
---Purpose: Returns AIS_InteractiveObject stored in the presentation attribute
AISUpdate (me : mutable)
---Purpose: Updates AIS_InteractiveObject stored in the attribute
-- and applies the visualization settings
is private;
AISDisplay (me : mutable)
---Purpose: Displays AIS_InteractiveObject stored in the attribute
is private;
AISErase (me : mutable; remove : Boolean from Standard = Standard_False)
---Purpose: Erases AIS_InteractiveObject stored in the attribute in
-- the viewer; If <remove> = True then AISObject is removed
-- from AIS_InteractiveContext instead of simple erasing in the viewer
is private;
---Category: Visualization settings of AIS_InteractiveObject
-- ================================================
Material(me) returns NameOfMaterial from Graphic3d;
---Purpose:
-- Returns the material setting for this presentation attribute.
SetMaterial(me : mutable; aName : NameOfMaterial from Graphic3d);
---Purpose: Sets the material aName for this presentation attribute.
HasOwnMaterial(me) returns Boolean from Standard;
---Purpose: Returns true if this presentation attribute already has a material setting.
UnsetMaterial(me : mutable);
---Purpose: Removes the material setting from this presentation attribute.
SetTransparency(me : mutable; aValue : Real from Standard=0.6);
--- Purpose:
-- Sets the transparency value aValue for this
-- presentation attribute.
-- This value is 0.6 by default.
Transparency(me) returns Real from Standard;
HasOwnTransparency(me) returns Boolean from Standard;
---Purpose: Returns true if this presentation attribute already has a transparency setting.
UnsetTransparency(me : mutable);
---Purpose: Removes the transparency setting from this presentation attribute.
Color(me) returns NameOfColor from Quantity;
SetColor(me: mutable; aColor : NameOfColor from Quantity);
---Purpose: Sets the color aColor for this presentation attribute.
HasOwnColor(me) returns Boolean from Standard;
---Purpose: Returns true if this presentation attribute already has a color setting.
UnsetColor(me : mutable);
---Purpose: Removes the color setting from this presentation attribute.
Width(me) returns Real from Standard ;
SetWidth(me: mutable; aWidth : Real from Standard);
---Purpose: Sets the width aWidth for this presentation attribute.
HasOwnWidth(me) returns Boolean from Standard;
---Purpose: Returns true if this presentation attribute already has a width setting.
UnsetWidth(me : mutable);
---Purpose: Removes the width setting from this presentation attribute.
Mode(me) returns Integer from Standard;
SetMode(me: mutable; theMode : Integer from Standard);
HasOwnMode(me) returns Boolean from Standard;
UnsetMode(me : mutable);
SelectionMode(me) returns Integer from Standard;
SetSelectionMode(me: mutable; theSelectionMode : Integer from Standard);
HasOwnSelectionMode(me) returns Boolean from Standard;
UnsetSelectionMode(me : mutable);
---Category: Methods of TDF_Attribute
-- ========================
ID(me)returns GUID from Standard;
---C++: return const &
NewEmpty(me)
returns mutable Attribute from TDF;
Restore(me: mutable; with : Attribute from TDF);
Paste (me; into : mutable Attribute from TDF;
RT : mutable RelocationTable from TDF);
BackupCopy(me) returns mutable Attribute from TDF is redefined;
---Category: Callbacks for viewer updating
-- =============================
AfterAddition (me: mutable)
is redefined;
BeforeRemoval (me: mutable)
is redefined;
BeforeForget(me: mutable)
is redefined;
AfterResume(me: mutable)
is redefined;
BeforeUndo (me: mutable; anAttDelta : AttributeDelta from TDF;
forceIt : Boolean from Standard = Standard_False)
returns Boolean from Standard
is redefined;
AfterUndo (me: mutable; anAttDelta : AttributeDelta from TDF;
forceIt : Boolean from Standard = Standard_False)
---Purpose: update AIS viewer according to delta
returns Boolean from Standard
