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:
- the line attributes (width, color etc.)
- arrow's style and attributes (color and size)
- arrow location on the edge.
Also you may use additional run-time capabilities:
- the edge nodes can be defined by controls
- the edge line can be multi-segment, i.e. polyline.
- you can determine if the point is on the graph edge.
- you can evaluate the exact point on edge - the nearest to an arbitrary
given point.
OnMouseDown event for this component occurs when you press a mouse button with the mouse pointer on line or arrow representing the graph edge, NOT on the whole control rectangle.
Various common control properties are available and several specific properties, methods and events are defined and implemented.
The TGraphLink component is shareware.
