How to use a custom icons? [message #1734135]

I need some help to load a custom image in my CustomShapeFeatureContainer.
I did not found out how to register custom icons located in the /icons/large/ folder.
I guessed the CustomTaskImageProvider.registerAvailableImages(); automatically registers all images in this folder. But it seems not to be the case.

What is necessary to be able to load a icon with something like this:

img = CustomTaskImageProvider.createImage(customTaskDescriptor, ga,
								"inbox.png", 24, 24);

All my attempts resulted in a red-box-icon which seems to indicate that I have not registered my image to Eclipse.

Hi Ralph, try this:

	String imageId = customTaskDescriptor.getImageId("inbox.png", CustomTaskImageProvider.IconSize.LARGE);
	if (!registered) {
		String filename = "/icons/large/inbox.png";
		URL url = getClass().getClassLoader().getResource(filename);
		ImageDescriptor descriptor =  ImageDescriptor.createFromURL(url);
		CustomTaskImageProvider.registerImage(imageId, descriptor);
		registered = true;
	}
	Image img = Graphiti.getGaService().createImage(ga, imageId);
	img.setProportional(false);
	img.setWidth(24);
	img.setHeight(24);
	img.setStretchH(true);
	img.setStretchV(true);
	Graphiti.getGaService().setLocation(img, 50, 25);
