UiBinder, can't even get to first base
John
various tutorials and examples and finally I have striped things down
to what I believe is the bare minimum.
It started as the standard Eclipse plugin generated application, and I
have discarded virtually everything.
What's left is:
public class TestUi implements EntryPoint {
@UiTemplate("TestUi.ui.xml")
interface TestBinder extends UiBinder<VerticalPanel, TestUi> { }
private static TestBinder testBinder = GWT.create(TestBinder.class);
public void onModuleLoad() {
VerticalPanel vp = testBinder.createAndBindUi(this);
RootPanel.get().add(vp);
}
}
----------------------------------------------------------------------
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'>
<ui:style>
.pretty { background-color: pink; }
</ui:style>
<g:VerticalPanel class='{style.pretty}' >
</g:VerticalPanel>
</ui:UiBinder>
-------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='testui'>
<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.google.gwt.user.theme.standard.Standard'/>
<!-- Other module inherits -->
<inherits name="com.google.gwt.uibinder.UiBinder" />
<!-- Specify the app entry point class. -->
<entry-point class='com.axxessible.testui.client.TestUi'/>
<!-- Specify the paths for translatable code -->
<source path='client'/>
</module>
-----------------------------------------------------------------------------
errors during compile, the lines below are in exactly the sequence shown:
Invoking com.google.gwt.dev.javac.StandardGeneratorContext@45800894
[ERROR] In <g:VerticalPanel class='{style.pretty}'>,
class VerticalPanel has no appropriate setClass() method
[ERROR] Errors in
'file:/home/john/workspace/TestUi/src/com/axxessible/testui/client/TestUi.java'
[ERROR] Line 32: Failed to resolve
'com.axxessible.testui.client.TestUi.TestBinder' via deferred binding
If I take out the class='----' out of the <g:VerticalPanel> then it
compiles. But if it's a panel widget, it should be able to set a
background-color, no?
I already know I'm doing something incredibly stupid, so I don't mind
if you skip telling me that part, and just tell me what it is!!
Thanks.

addStyleNames instead of class.
Hope that helps.

In the older GWT versions, I know you set the stylename and used a
conventional CSS style sheet with those names.
I thought UIBinder was a whole new thing--I was trying to follow the
tutorials as closely as possible, and they inserted class=xxxx, which
is one of the standard ways of marking CSS styles, isn't it?

If you want to set CSS class names on GWT widgets using UI binder you
need to use the methods I mentioned.

Arthur, thanks. Someplace I saw some debate about whether UI Binder
was worthwhile. Now I see why it's in dispute.

Ahhhh, I finally got it. I wish I hadn't wasted so much time reading
tutorials and other "helpful" guides. The real scoop is right here:
