background images and image bundles howto

[jhudson8]

Hi,

I've created an image bundle

public interface LayoutImagesBundle extends ImageBundle {

public AbstractImagePrototype layout_bg();
}

I'm trying to set the background image of a canvas with this image but I only see a string as a parameter...
canvas.setBackgroundImage(String) - can someone give me a tip as to how this should be done? Thanks.

So, it seems like SmartGWT doesn't work with GWT ImageBundles... is this correct?

I don't necessarily have to use ImageBundles - I just want a background image to show up - can anyone give me an example of what I would need to do to have a custom image render as a background image for a canvas? Thank you very much.

It looks like that the imageBundle works for stand alone images in layouts and other components, but when it is used for setting up a background image of these elements it returns the whole bundle. That is all the images in one and not just the one specified.

For example:

VLayout vLayout = new VLayout();

vLayout.setWidth100();
vLayout.setHeight100();

Image loginImage = MyBundleImages.Impl.getInstance().loginBackgroundImg().createImage();

vLayout.setBackgroundImage(loginImage.getUrl());
vLayout.draw();

where MyBundleImages is:

public interface MyBundleImages extends ImageBundle {

	@Resource("image1.jpg")
	AbstractImagePrototype loginBackgroundImg();
	
	@Resource("image2.gif")
	AbstractImagePrototype logoImg();
	
	public static class Impl {
	    	
		private static MyBundleImages instance;

		public static MyBundleImages getInstance() {
			if (instance == null) {
				instance = GWT.create(MyBundleImages.class);
			}
			return instance;
		}
	}

}

This will return a composite image of image1 and image2 and not just image1.
Any way to overcome this with using bundles? Or do I have to go to plain URLs?
