The AllGraph Package (AGP) is a toolbox that allows Delphi programmers to easily and quickly develop applications that manipulate large graphs. The AllGraph Package (AGP) is a toolbox that allows Delphi programmers to easily and quickly develop applications that manipulate large graphs. Extended features have been included, including special types of selection, advanced editing, copy&paste options. For example, changing a subgraph into a complete graph or into its own complementary graph can be done by a simple call of one function available in AllGraph. Detection of the DFS or the BFS subtrees, of connected components, or of shortest paths are several features that provide powerful control over graph manipulation. AllGraph supports both directed and undirected graphs, but it does not support multigraphs or hypergraphs. An additional goal of this package is graph visualization. A simple function call will draw the graph on an appropriate graphic support.
