org.eclipse.wb.swt.SWTResourceManager

public class SWTResourceManager
extends java.lang.Object

Utility class for managing OS resources associated with SWT controls such as colors, fonts, images, etc.

!!! IMPORTANT !!! Application code must explicitly invoke the dispose() method to release the operating system resources managed by cached objects when those objects and OS resources are no longer needed (e.g. on application shutdown)

This class may be freely distributed as part of any application or plugin.
