public class ModeCreateEdgeAndNode
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.

ModeCreateEdgeAndNode

public ModeCreateEdgeAndNode(Editor ed,
                             Class edgeClass,
                             Class nodeClass,

Method Detail

setup

public void setup(FigNode fn,
                  Object port,
                  int x,
                  int y,
                  boolean reverse)

instructions

public String instructions()
Overrides:
instructions in class Mode

createNewItem

public Fig createNewItem(MouseEvent me,
                         int snapX,
                         int snapY)
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.
Overrides:
createNewItem in class ModeCreate

done

public void done()
Overrides:
done in class Mode

mousePressed

public void mousePressed(MouseEvent me)
On mousePressed determine what port the user is dragging from. The mousePressed event is sent via ModeSelect.
Overrides:
mousePressed in class ModeCreate

mouseReleased

public void mouseReleased(MouseEvent me)
On mouseReleased, find the destination port, ask the GraphModel to connect the two ports. If that connection is allowed, then construct a new FigEdge and add it to the Layer and send it to the back.
Overrides:
mouseReleased in class ModeCreate

mouseMoved

public void mouseMoved(MouseEvent me)
Overrides:
mouseMoved in class Mode

mouseDragged

public void mouseDragged(MouseEvent me)
Overrides:
mouseDragged in class ModeCreate

keyTyped

public void keyTyped(KeyEvent ke)
Overrides:
keyTyped in class Mode

postProcessEdge

public void postProcessEdge()
