- public class ModeCreateEdge
- extends ModeCreate
A Mode to interpret user input while creating an edge. Basically
mouse down starts creating an edge from a source port Fig, mouse
motion paints a rubberband line, mouse up finds the destination port
and finishes creating the edge and makes an FigEdge and sends
it to the back of the Layer.
The argument "edgeClass" determines the type if edge to suggest
that the Editor's GraphModel construct. The GraphModel is
responsible for acutally making an edge in the underlying model
and connecting it to other model elements.

createNewItem
public org.tigris.gef.presentation.Fig createNewItem(java.awt.event.MouseEvent me,
int snapX,

- Create the new item that will be drawn. In this case I would
rather create the FigEdge when I am done. Here I just
create a rubberband FigLine to show during dragging.
