package DBRep 

 ---Purpose: Used to display BRep objects  using the DrawTrSurf
	--          package.
	--  The DrawableShape is a Display object build from a
	--          Shape.
     --  Provides methods to manage a directory of named shapes.
	--          Provides a set of Draw commands for Shapes.

is

    class Edge; 
	---Purpose: Display of an edge. Edge + color.
	
    class ListOfEdge instantiates 
    List from TCollection(Edge from DBRep);

    class Face;
	---Purpose: Display of a face. Face + Array of iso + color.
	
    class ListOfFace instantiates 
    List from TCollection(Face from DBRep);

    class HideData;
	---Purpose: Hidden lines data for a view

    class ListOfHideData instantiates
    List from TCollection(HideData from DBRep);

    class DrawableShape;
	---Purpose: Drawable structure to display a  shape. Contains a
	--          list of edges and a list of faces.
    
    class IsoBuilder;
	---Purpose: Creation of isoparametric curves.

    --  class ProgressIndicator;
    ---Purpose : Implements ProgressIndicator for DRAW

    --  Methods to manage variables
    --  
    
    Set(Name : CString; S : Shape from TopoDS);
	---Purpose: Sets  <S> in the  variable  <Name>.  Overwrite the
	--          variable if already set.
	
    Get(Name : in out CString; 
    	Typ  : ShapeEnum from TopAbs = TopAbs_SHAPE;
        Complain : Boolean = Standard_False) 
    returns Shape from TopoDS;
	---Purpose: Returns the shape in the variable  <Name>. Returns
	--          a null shape if the variable is not set or  not of
	--          the given <Typ>.  If <Complain> is  True a message
	--          is printed on cout if the variable is not set.

    BasicCommands(theCommands : in out Interpretor from Draw);
	---Purpose: Defines the basic commands.
	
    HLRMode returns Boolean from Standard;
    	---Purpose: True if HLR, False if wireframe.

    Rg1Mode returns Boolean from Standard;
    	---Purpose: True if display Rg1Lines.

    RgNMode returns Boolean from Standard;
    	---Purpose: True if display RgNLines.

    HidMode returns Boolean from Standard;
    	---Purpose: True if display HiddenLines.

    HLRAngle returns Real from Standard;
    	---Purpose: discretisation angle for edges.

    NbIsos returns Integer from Standard;
	---Purpose: number of iso in U and V
    
    Discretisation returns Integer from Standard;
	---Purpose: discretisation number of points for curves
	
    --SetProgressBar(thePI: ProgressIndicator from Message);
        ---Purpose: set progress indicator
	
    --GetProgressBar returns ProgressIndicator from Message;
        ---Purpose: get progress indicator
