Hi,
I'm trying to get some modular app desgin working using GWT and MVP.
But now I'm stuck in some ClientBundle issue.
I wanted to create a ClientBundle for my header widget which contains
the CSS information and image resources. CSS definitions should be
stored in a seperate file called header.css and after working with the
"Developers Guide - UiBinder" I tried the following approach:
public interface Resource extends ClientBundle {
public interface HeaderCss extends CssResource{
public String headerBanner();
public String menuItem ();
public String selected ();
public String hovered();
public String langswitch();
public String nav();
}
@Source("header.css")
public HeaderCss css();
@Source("header_bg.png")
public ImageResource headerBackground();
}
this interface is included into header.ui.xml by:
<ui:style src="resource/header.css"
type="appgui.client.ui.widgets.header.resource.Resource.HeaderCss"/>
I now want to know how to include ImageResource headerBackground(); in
my header.css
I tried to do this by using the @sprite annotation as described in GWT
CSS CookBook (referenced by
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/f3ba1d8dfc9d67f8/b5bf0790aca915ea?lnk=gst&q=cssresource#b5bf0790aca915ea)
but i couldn't get it working. GWT plugin in eclipse announces
[ERROR] [appgui] Unable to find ImageResource method
value("headerBackground") in
appgui.client.ui.widgets.header.Header_HeaderUiBinderImpl_GenBundle :
Could not find no-arg method named headerBackground in type
appgui.client.ui.widgets.header.Header_HeaderUiBinderImpl_GenBundle
My Header class is set up in the way Developer Guide describes:
public class Header extends Composite {
private static HeaderUiBinder uiBinder =
GWT.create(HeaderUiBinder.class);
interface HeaderUiBinder extends UiBinder<Widget, Header> {
}
@UiField
HeaderCss style;
...
public Header(String firstName) {
initWidget(uiBinder.createAndBindUi(this));
....
}
...
}
header.css:
@sprite .headerBanner {
gwt-image: 'headerBackground';
height: 100px;
width: 100%;
margin: 0px;
}
I think my current Problem is, that I have missunderstood the usage of
either @sprite or the ClientBundle or both.
