为什么无法从我的项目中获取 GWT UI 绑定器模板以使用客户端bundle

Question

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
    xmlns:g='urn:import:com.google.gwt.user.client.ui'>
    <ui:with field='res' type='com.myproject.resources.Resources'/>
    <ui:style>
        .panel {
            background-color: ivory;
        }
    </ui:style>
    <g:FlowPanel styleName='{style.panel}'>
        <g:Image url='{res.logo}'/>
        <g:VerticalPanel>
            <g:PushButton text="My Button" ui:field="myButton"></g:PushButton>
        </g:VerticalPanel>
    </g:FlowPanel>
</ui:UiBinder>

我有一个资源类

public interface  Resources extends ClientBundle {
      public static final Resources INSTANCE =  GWT.create(Resources.class);
      @Source("logo.png")
      ImageResource logo();

}

我在 GWT XML 编辑器中没有收到任何错误，但是，GWT 设计器不会加载。当我运行它时，我也会出现异常。

Answer 1

很难

判断是否是您的问题，但您的代码应该是：

<g:Image resource='{res.logo}'/>

（即 resource，不是url）

Answer 2

确保在你的 gwt.xml 文件中有这个继承标签，在使用 ClientBundle 时是必需的：

<inherits name="com.google.gwt.resources.Resources" />
