Field Detail

generator

private static Random generator

dragged

protected boolean dragged

Whether the node is currently being moved with the mouse.

Constructor Detail

NwNode

protected NwNode(Element config,
                 float factor,
                 String iconPath,
                 VerinecStudio gui,
                 int type)

Passes the parameters to the super class.

Parameters:

config - The XML config element of the component. If you have none, use createElement to produce one.

factor - A ratio to the default size.

iconPath - The location where the icon can be found.

gui - The main application.

type - The network type of this node.

Method Detail

initialize

public void initialize()

Lets the super class perform the initialization, then re-adds the mouse listeners.

Overrides:

initialize in class NwComponent

getLayoutChild

protected Element getLayoutChild(Element config)

Extract the node gui information child from the configuration, add a default if necessary.

Specified by:

getLayoutChild in class NwComponent

Parameters:

config - The network xml object.

Returns:

A gui element from configuration namespace.

setBounds

public void setBounds(int x,
                      int y,
                      int w,
                      int h)

Set the position and size of the node. Update the meta information with the new coordinates.

Overrides:

setBounds in class NwComponent

Parameters:

x - Top left corner x coordinate

y - Top left corner y coordinate

w - With of component

h - Height of component

resizeComponent

public void resizeComponent(float factor)

Resizes the node, adjusting it to its new size and also moves it to the right location if we zoom in or out. Overwrites NwComponent.resizeComponent(float) to also move the node.

Overrides:

resizeComponent in class NwComponent

Parameters:

factor - the resize factor for the icon.

addNodeinfoElement

protected void addNodeinfoElement(int posX,
                                  int posY)

Adds the layout tag to the defintionelement of the component.

This tag contains the coordinates of the component. Take care to normalise them to zoom factor 1 before calling this method.

Parameters:

posX - the x position that shall be added.

posY - the y position that shall be added.

createNodeInfo

protected static Element createNodeInfo(Element config,
                                        int x,
                                        int y)

Create the node layout information and add it to the config.

Parameters:

config - The node configuration the node info will be attached to.

x - coordinate.

y - coordinate.

Returns:

The generated node information element.
