I have setup a global ClientBundle for my app that contains a global
CssResource. I want the global CssResource to make available certain
constants (such as colors, font sizes, and so forth) so those style
definitions may easily be reused elsewhere in my application - as
dependent styles, if you will.
Below are several code files illustrating what I'm trying to do:
>> Global.java
public interface Global extends ClientBundle {
public interface Style extends CssResource {
String getLightColor();
String getDarkColor();
}
@Source("global.css")
Style style();
}
<<
>> global.css
@def darkColor #333333;
@def lightColor #CCCCCC;
<<
>> MyEntryPoint.java
public class MyEntryPoint implements EntryPoint {
public void onModuleLoad() {
GWT.<Global> create(Global.class).style().ensureInjected();
RootPanelLayout.get().add(new MyWidget());
}
}
<<
>> MyWidget.java
public class MyWidget extends Composite {
interface Binder extends UiBinder<Widget, MyWidget> {}
private static Binder binder = GWT.create(Binder.class);
public MyWidget() {
initWidget(binder.createAndBind(this));
}
}
<<
>> MyWidget.ui.xml
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<ui:with field="global" type="Global" />
<ui:style>
@def DARK value('global.style.darkColor');
.myStyle {
background-color: value('global.style.darkColor'); /* method 1:
this doesn't work */
}
.foo {
background-color: DARK; /* method 2: this doesn't work either */
}
</ui:style>
<g:HTML styleName="{style.myStyle}">
<span class="{style.foo}" style="color:
{global.style.lightColor};">Method 3: This text is colored properly
when using the inline style attribute.</span>
</g:HTML>
</ui:UiBinder>
<<
Does anyone have a suggestion as to how I could use the colors defined
in Global.Style in other contexts, such as UiBinder *.ui.xml layouts?
With methods 1 or 2 above, I get a compiler error as follows:
00:38:55.817 [ERROR] Could not find no-arg method named global in type
MyWidget_BinderImpl_GenBundle
Clearly the generators can find the styles I'm interested in, since
method 3 does work, albeit incredibly cumbersome...
