Question

How do I make sure that certain types of IltObject are always drawn on top of another type of IltObject?

Answer

This type of issue is commonly addressed with the use of the JViews TGO layering mechanism.
To make sure that the instances of a type MyIltObjectOne are drawn on top of the instances of a type MyIltObjectTwo, start by creating a layer for your MyIltObjectOne objects and another layer for your MyIltObjectTwo objects. Then, make sure that the MyIltObjectOne layer is in a higher position or index than the MyIltObjectTwo layer.

As a result, the MyIltObjectOne objects should be drawn on top of the MyIltObjectTwo objects and not below them.

Refer to the following ILOG JTGO resources for more information on layers:

  • Documentation: JViews TGO / Programmers documentation / Graphic components / Network component / Network component services / Layers
  • Sample: JTGO_HOME/samples/network/decoration
  • FAQ: How do I implement my own layer policy?
