Background image on Composite [message #723481]

I set the background image of a composite:

composite.setBackgroundImage(image);

The problem is that the image is smaller than the composite, and the image is tiled. How can I change it so that the image is either centered or stretched within the composite? Is there a way to control the image location within the composite?

Thanks.

Paint the image using a paint listener and change the image size by modifying the image data and getsize method of composite...

I tried manipulating the ImageData, but when I call the composite's getsize() I get a Point with 0 width and 0 height.

Point compositeSize = composite.getSize();

Try using .getClientArea ()

also confirm the layout on the parent of the composite,it should be a Fill or somthing which does not ask the composite what its size should be(assuming u dont have child controls on the composite-if it is not the case then use canvas)

Also Refer this http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet48.java
