Manipulate the size of the network element

Question

Can I change the size of my network element?

Answer

There are many ways to change the size of an IltNetworkElement.

You can:

• collapse it
• apply a transformer on its base
• use the network element drawer

1. Collapse the Network Element

   The first solution consists in using the collapse feature of the network element.

   When the network element is collapsed, its size is reduced to 53.5% of the normal size, which corresponds to the small size listed in the table at the end of this page.

   Use the CSS property collapsed as listed in the IltNetworkElement.IsCollapsed Javadocs.

   Here is a CSS extract to illustrate this point:

   #nodeID {

   collapsed: true;

   }

2. Use a Transformer

   Use the CSS property sizeRatio as listed in the IltNetworkElement.SizeRatio Javadocs.

   Here is a CSS extract to illustrate this point:

   #nodeID {

   sizeRatio: "0.8, 0, 0, 0.8, 0, 0";

   }

3. Use the Network Element Drawer

   The last solution is to customize the network element, as explained in the paragraph Styling / Customizing network elements / Customizing Network Element Types / Customizing Existing Network Element Types of the JTGO User's Manual.

   This solution consists in changing the mapping of an existing type of network element, or creating a new type of network element.

   This has to be done before creating the network element.

   Here is a method to change the mapping of an existing type (NE in the sample):

   public static void ChangeTypeMapping () {

   IltNetworkElement.SetTypeMapping(IltNetworkElement.Type.NE,

   new IltNEDrawerFactory() {

   public IltNEDrawer create (IltObject object,

   IltcCompositeGraphic graphic) {

   return new IltNetworkElement.NEDrawer() {

   public Dimension getPreferredSize (boolean collapsed) {

   if (collapsed)

   // small Size

   return new Dimension(27, 27);

   else

   // Normal Size

   return new Dimension(50, 50);

   }

   };

   }

   });

   Here is how to create a new type of network element:

   // declare the new type

   public static IltNetworkElement.Type SmallNetwork = new IltNetworkElement.Type("smallNetwork");

   // set the mapping

   IltNetworkElement.SetTypeMapping(SmallNetwork,

   new IltNEDrawerFactory() {

   public IltNEDrawer create (IltObject object,

   IltcCompositeGraphic graphic) {

   return new IltNetworkElement.NEDrawer() {

   public Dimension getPreferredSize (boolean collapsed) {

   if (collapsed)

   // small Size

   return new Dimension(13, 13);

   else

   // Normal Size

   return new Dimension(24, 24);

   }

   };

   }

   });

   // create a new network element with the new type

   IltNetworkElement paris =

   new IltNetworkElement("Paris", SmallNetwork,

   IltNetworkElement.Function.SwitchCrossConnect,

   null,

   new IltOSIObjectState());

The following table lists the sizes for each network element type:
