[news.eclipse.platform.swt] Re: Using an Image Descriptor in a Form (org

["Deborah Steiner" <debbiecadranel@xxxxxxxxx>]

The method creates an instance of Image class but it cannot be processed by 
a form's setBackgroundImage method.

The descriptor.createImage(Display.getCurrent());  returns an Image.

When this image is passed to  form.getBody().setBackgroundImage(image);:

I get this exception:


java.lang.IllegalArgumentException: Argument not valid

     at 
org.eclipse.swt.widgets.Control.setBackgroundImage(Control.java:2446)



Thanks
