FlowCanvas ---- FlowCanvas is an interactive Gtkmm/Gnomecanvasmm widget for graph-based interfaces (patchers, modular synthesizers, finite state automata, interactive graphs, etc). FlowCanvas provides classes for "Modules" (boxes with "Ports"), Ellipses, and Connections (lines that connect either Ports or Ellipses). The user can rearrange items, or FlowCanvas can automatically arrange items using GraphViz. Connections can be made by the user one at a time with the mouse, or in groups using the mouse and keyboard.
