Class ImageLoader

java.lang.Object
com.biglybt.ui.swt.imageloader.ImageLoader
All Implemented Interfaces:
AEDiagnosticsEvidenceGenerator
public class ImageLoader extends Object implements AEDiagnosticsEvidenceGenerator
Loads images from a skinProperty object.

Will look for special suffixes (over, down, disabled) and try to load resources using base key and suffix. ie. loadImage("foo-over") when foo=image.png, will load image-over.png

Will also create own disabled images if base image found and no disabled image found. Disabled opacity can be set via imageloader.disabled-opacity key
