UIBinder & sprite

[MeiAestro]

I am a bit confused regarding the use of sprites in UIBinder Classes.
As I was not able to use a css with sprites in a UIBinder XML I was
searching the web for this problem and found this issue:

http://code.google.com/p/google-web-toolkit/issues/detail?id=5320

On the other hand exactly this scenario is described in the GWT
Developer pages' examples (i.e. here:
http://code.google.com/intl/de/webtoolkit/doc/latest/DevGuideUiBinder.html
)

Can anybody bring light in the dark?

Thanks!

The difference is that the Dev Guide references a ClientBundle (with its own CssResource) from a UiBinder file, whereas in the issue, the OP tries to create a CssResource (ui;style) referencing an ImageResource declared in another ClientBundle.

You currently have a choice:

• either use ClientBundle+ImageResource+CssResource, following http://code.google.com/webtoolkit/doc/latest/DevGuideClientBundle.html
• or benefit from the implicit ClientBundle created by UiBinder, using ui:style to generate a CssResource, and ui:image to generate an ImageResource (and ui:data for a DataResource, FWIW)

Unfortunately, ui:image is not documented in the Dev Guide, but you'll find examples in the "mail" and "expenses" samples (actually, you'll even find on in the JavaDoc for CustomButton: http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/CustomButton.html )
