Class RouterGraphHelper

java.lang.Object
  net.clackrouter.router.graph.RouterGraphHelper

public class RouterGraphHelper
extends java.lang.Object

Main GUI class to handle the JGraph end of components being added, removed, and connected within Clack.

Every ClackGraphpad has a reference to a ClackGraphHelper

Constructor Summary

RouterGraphHelper(ClackFramework gp)

Method Summary

ComponentCell	addRouterComponentCell(Router router, ClackComponent component, java.awt.geom.Rectangle2D bounds) Adds a ComponentCell to the RouterGraph representing the router that was passed to the ClackComponent when it was created.
void	addRouterWire(ComponentCell sourceCell, int src_port_num, ComponentCell targetCell, int target_port_num) Adds a RouterWire to the graph between two component ports that have been connected.
void	attemptPortConnection(DefaultPort source_port, DefaultPort target_port) Show connection dialog to connect two ports and attempt to make the connection
void	cellRemovedFromModel(DefaultGraphCell cell) Called when ClackDocument.graphChanged(GraphModelEvent) recognizes that something has been removed from the RouterGraph.
static void	showConnectionErrorDialog(java.awt.Component comp, java.lang.String msg)

Method Detail

addRouterComponentCell

public ComponentCell addRouterComponentCell(Router router,
                                            ClackComponent component,
                                            java.awt.geom.Rectangle2D bounds)

Adds a ComponentCell to the RouterGraph representing the router that was passed to the ClackComponent when it was created.

This keeps the graph in synch with the router when a component is added. Components are added with the specified bounds, or at the location of the last click if no bounds are provided.

Parameters:

component - - component added to the router

bounds - - location in RouterGraph to add componentCell

Returns:

the created cell

addRouterWire

public void addRouterWire(ComponentCell sourceCell,
                          int src_port_num,
                          ComponentCell targetCell,
                          int target_port_num)

Adds a RouterWire to the graph between two component ports that have been connected.

Parameters:

sourceCell - source component cell

src_port_num - source port number

targetCell - target component cell

target_port_num - target port number

attemptPortConnection

public void attemptPortConnection(DefaultPort source_port,
                                  DefaultPort target_port)

Show connection dialog to connect two ports and attempt to make the connection

Parameters:

source_port -

target_port -

cellRemovedFromModel

public void cellRemovedFromModel(DefaultGraphCell cell)

Called when ClackDocument.graphChanged(GraphModelEvent) recognizes that something has been removed from the RouterGraph.

If a RouterWire has been removed, we disconnect the underlying ports

If a component has been removed, we delete all edges connected to this component

Parameters:

cell - - cell that has been removed from the graph

showConnectionErrorDialog

public static void showConnectionErrorDialog(java.awt.Component comp,
                                             java.lang.String msg)
