QuantoDerive
QuantoDerive is the new scala-based GUI that will replace the existing Quantomatic GUI. These pages are for planning various aspects of the tool.
The graph editor can be run stand-alone or (ultimately) inside of QuantoDerive. Its designed to be as simple as possible, and does not need to communicate with the core. It loads and saves files in the .qgraph file format. For more info, see file formats.
Many aspects of the interface are obvious, so here are suggestions on how to do the less obvious things.
Currently, all vertices are laid out with fixed positions. However, it might be nicer to only give fixed positions for node-vertices and boundaries (i.e. wire-vertices with one or zero adjacent edges), then lay out the intermediate nodes automatically. For multiple wires between two node-vertices, it would look nice to lay out wire-vertices interpolated along the bezier curve of each edge.
The intermediate wire-vertices should be selectable, but not draggable. Deleting a wire-vertex would upgrade its neighbour(s) to boundaries.
