  javax.swing.plaf.metal.MetalIconFactory.ImageCacher

Enclosing class:

MetalIconFactory

static class MetalIconFactory.ImageCacher

extends Object

Utility class for caching icon images. This is necessary because we need a new image whenever we are rendering into a new GraphicsConfiguration, but we do not want to keep recreating icon images for GC's that we have already seen (for example, dragging a window back and forth between monitors on a multimon system, or drawing an icon to different Components that have different GC's). So now whenever we create a new icon image for a given GC, we cache that image with the GC for later retrieval.
