UiBinder中的gwt pushButton [英] gwt pushButton in UiBinder

问题描述

我需要用 UiBinder 在 gwt 中创建一个pushButton（所以它是一个带图片的按钮），但是我我不知道如何继续。这是我的 ui.xml 代码：

I need to create a pushButton(so it's a button with image) in gwt with UiBinder, but I'm not sure how proceed. Here is my ui.xml code:

<g:PushButton ui:field="myPushButton"/>

在* .java文件中，我定义了：
PushButton myPushButton; code>

And in *.java file I defined:
PushButton myPushButton;

如何将图像添加到按钮？我尝试了以下方法，但无效：

How can I add an image to the push button? I've tried the following but won't work:

<g:PushButton ui:field="myPushButton" image="myImage.gif" />

谢谢

Thanks

推荐答案

使用下面的代码直接从CustomButton Javadoc：

You can use following code straight from CustomButton Javadoc:

g:PushButton ui:field='pushButton' enabled='true'>
   <g:upFace>
     <b>click me</b>
   </g:upFace>
   <g:upHoveringFace>
     <b>Click ME!</b>
   </g:upHoveringFace>

   <g:downFace image='{downButton}'/>
   <g:downHoveringFace image='{downButton}'/>
 </g:PushButton>
