The TGraphLink component is designed to represent and display graph edge for both directed and undirected graphs in a Borland Delphi or C++Builder program. It is a line connecting two points (nodes) and optional one or two arrows on this line. You can change such attributes as line width, arrow's style, color and size, arrow location on the edge. You can designate other controls for the ends of the line in which case the ending points will be calculated automatically according to the shapes of those controls. The line may be constructed as multi-segment. Printing (to an arbitrary canvas) and exporting to metafiles are supported. At run-time you can determine if the point is on the graph edge. OnMouseDown event for this component occurs when you press a mouse button with the mouse pointer on line or arrow representing the graph edge. Also, run-time hints are supported. Delphi/C++Builder versions supported: Delphi 1/2/3/4 and C++Builder 1/3.
