class DrawPresentation from DDataStd inherits Attribute from TDF
---Purpose: draw presentaion of a label of a document
uses GUID from Standard,
AttributeIndexedMap from TDF,
DataSet from TDF,
AttributeDelta from TDF,
Label from TDF,
RelocationTable from TDF,
Drawable3D from Draw
is
---Purpose: api methods on draw presentation
-- ================================
HasPresentation (myclass; L : Label from TDF)
returns Boolean from Standard;
IsDisplayed (myclass; L : Label from TDF)
returns Boolean from Standard;
Display (myclass; L : Label from TDF);
-- display <L> presentation in draw viewer.
Erase (myclass; L : Label from TDF);
-- erase <L> in draw viewer
Update (myclass; L : Label from TDF);
-- recompute and display L in draw viewer
---Purpose: attribute implementation
-- ========================
GetID(myclass) returns GUID from Standard;
---C++: return const &
Create returns mutable DrawPresentation from DDataStd;
SetDisplayed (me : mutable; status : Boolean from Standard);
IsDisplayed (me)
returns Boolean from Standard;
SetDrawable (me : mutable; D : Drawable3D from Draw);
GetDrawable (me)
returns Drawable3D from Draw;
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);
---Purpose: call backs 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

forceIt : Boolean from Standard = Standard_False)
---Purpose: update draw viewer according to delta
returns Boolean from Standard

---Purpose: private methods
-- ===============
