Editing the graph

Create nodes with the Insert Node button.
Delete nodes with Ctrl-click.
Edit a nodes label by double-clicking the node.
Choose a start node by using Shift-Ctrl-click on that node.
Create an edge by holding down Shift and dragging from one node to another.
Delete an edge by Ctrl-click on the edges weight.
Edit an edges weight by double-clicking the edge's weight.
Clear the graph by pressing Clear.
Choose an example graph by pressing either Example 1 or Example 2 buttons. Warning: pressing these button also clears the graph.

Right click on either a node or an edge to get a context menu of options.
Node - Edit, Set as start, Delete
Edge - Edit, Delete

Running SPF algorithm

Note that the SPF algorithm breaks if there are any negative weights in the graph. Try it out!

Chose a start node.
Press the Run SPF button. Button should become the Stop button. This also disables the editing area and all buttons.
You an press Stop during the execution of the algorithm to stop it. The button will change to Reset.
Look at the textual output of the algorithm using the scroll bars of the text area.
Once the algorithm is finished (or you press Stop) the button changes to Reset. The editing area will be enabled again once you press this button.

Cyan	Normal colour for nodes.
Black	Normal colour for edges.
Magenta	The start node
Red	Visited nodes and candidate edges
Pink	Processed nodes and edges along the minimum path. Follow the pink edges from the start node to the other nodes to find the minimum path.
