- GraphStar is a set of components and objects to help Delphi users
- to develop their graph applications easily. A graph in GraphStar is
- a set of vertices,edges,touch-objects and faces:
-
- Vertices: points of 2D long integer domain;
- Edges: links connects a pair of vertices;
- Touch-objects : those objects touched on other objects;
- Face : object to keep edges of a face of a planar graph.
-
- Data structure of a graph can be recursive.
-
-
- For drawing diagrams such as flow chats, following objects are also
- supported at GraphStar:
-
- - FCVertex: vertices with shape-polygon such as rectangle,circle, etc.
- - FCEdge: edges to connect FCVertex.
-
- GraphStar provides well-defined object structures and implements
- lower level functions about graph applications such as
-
- - sorting and hit-testing of objects
- - manipulation of objects
- - interactive drawing
- - save/load
- - undo/redo functions*
- - planarity test*
- - property editor
- - calculation of user-defined marcos.*
-
- GraphStar is a freeware before version1.0. In these cases, you can
- use it on your programs, but remember there possibly have some bugs
- somewhere. Well, if there are more than 25 objects in the graph, the GSPanel
- showes a unregistered string.
