public class ModeCreateForeignKey

extends org.tigris.gef.base.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,
                                                     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.

createNewItem in class org.tigris.gef.base.ModeCreate

mousePressed

public void mousePressed(java.awt.event.MouseEvent me)

On mousePressed determine what port the user is dragging from. The mousePressed event is sent via ModeSelect.

Specified by:

mousePressed in interface java.awt.event.MouseListener

Overrides:

mousePressed in class org.tigris.gef.base.ModeCreate

mouseReleased

public void mouseReleased(java.awt.event.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.

Specified by:

mouseReleased in interface java.awt.event.MouseListener

Overrides:

mouseReleased in class org.tigris.gef.base.ModeCreate
