Question
How to count the number of IlvGraphic objects currently visible in IlvManagerView?
Answer
You can easily retrieve the number of graphical objects of a manager with the IlvManager.getObjects() method, but getting the number of objects that are visible on the screen must be done with a small routine.
The attached sample CountObject.java illustrates a way of doing that by using the IlvManager.mapIntersects() method and a class that implements IlvApplyObject.
Note: In order to run this sample with JViews 8.7 and later, you must call the log.views.util.IlvProductUtil.DeploymentLicenseRequired method with the appropriate argument. See the General information > Deployment licenses > Declaring the use of IBM ILOG JViews services section in the documentation for more information.
