Question

我正试图在“地平线”内带两个县,以展示形象。你们不像在座的县那样,然后看一页,看上去看形象,但你看上去形象,而且上面有县。

这是我迄今为止在我的档案中制定的法典:

 <g:FocusPanel ui:field="profileImagePanel" addStyleNames="{style.headerImage}">
     <g:AbsolutePanel addStyleNames="{style.innerImagePanel}">
         <g:Image ui:field="profileImage" addStyleNames="{style.profileImage}"/>
         <g:HorizontalPanel ui:field="imageEditButtons" addStyleNames="{style.imageEditButtons}">
             <w:MultiUseButton ui:field="clearImage" addStyleNames="{style.change}" type="secondary" text="{i18n.clearImage}" visible="false"/>
             <w:MultiUseButton ui:field="changeImage" type="secondary" text="{i18n.changeImage}" visible="false"/>
         </g:HorizontalPanel>
     </g:AbsolutePanel>
 </g:FocusPanel>

风格如下:

.headerImage {
    position: absolute;
    top: 0;
    left: 0;
    width: 150px;
}

.profileImage {
    width: 150px;
    position: relative;
}

.change {
    float: right;
}

.headerImage a {
    display: block;
}

.imageEditButtons {
    width:100%;
}

.innerImagePanel {
    width:150px;
}

I ve tried using a FlowPanel instead of an AbsolutePanel, but that doesn t work. I ve tried making the profileImage position:relative and imageEditButtons position:absolute but that screws up the whole display of the rest o the page. I also tried setting imageEditButtons margin-top:-20px but it goes underneath the image instead of on top. If I put the HorizontalPanel in the AbsolutePanel before the Image, then the buttons are above the image and if I try changing the top margin, it shifts the buttons and Image down.

我 ideas弃思想。任何关于如何开展这项工作的建议都会受到高度赞赏。

采用<条码>背井离层而不是使用植被Image。这里我想到的是你UiBinder案的内容:

<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
     xmlns:g="urn:import:com.google.gwt.user.client.ui">
   <ui:style>
       /* requirement style */
       .myPanel {
           width: 200px; /* width of your background image */
           height: 400px; /* height of your background image */     
           background-image: url(images/myimage.jpg); /* your image */
           background-repeat: no-repeat;
       }

       /* optional style */
       .myButton {
           margin: 10px;
           width: 80px;
           height: 40px;
       }
   </ui:style>
   <g:HTMLPanel>
       <g:FocusPanel ui:field="profileImagePanel">
           <g:AbsolutePanel addStyleNames="{style.myPanel}">
               <g:HorizontalPanel ui:field="imageEditButtons">
                   <g:Button ui:field="clearImage" text="clear image" addStyleNames="{style.myButton}" />
                   <g:Button ui:field="changeImage" text="second button" addStyleNames="{style.myButton}" />
               </g:HorizontalPanel>
           </g:AbsolutePanel>
       </g:FocusPanel>
   </g:HTMLPanel>

中文无需改动。你的风格可以带上你的文件。因此,你们应当得到你们的希望。在这种情况下,需要AbsolutePanel。简单的流程图也合适。
