File Menu

The file menu only appears in the NetWorKs application, and it allows users to save and retrieve graphs to and from files. The save and open menu options take into account that the GraphPanel actually contains two distinct graphs. The save menu option will save the currently displayed graph in the specified file. The open option allows users to select a file name and then replaces the appropriate graph in memory with the graph from the file. Files are text, and use a combined vertex, edge list format. They may be modified directly by a word processor. Figure 3 shows the file generated by saving the graph in Figure 1.
