为什么这个uibinder页面没有垂直滚动条? [英] Why doesn't this uibinder page have a vertical scrollbar?

问题描述

我希望浏览器在内容大于页面时显示垂直滚动条.内容和页脚消失在屏幕下方，而不是显示垂直滚动条(就像我们在SO主页上看到的那样).

I want the browser to show a vertical scrollbar when the content grows larger than the page. The content and footer disappear below the screen instead of showing a vertical scroll bar (like we see on the SO home page).

我问了类似的问题较早，但这是针对页面页脚随内容增长而不会扩展的原因.我已经解决了这个问题，但是现在页脚向南移动，但是页面滚动条从不显示.

I asked a similar question earlier, but it was directed at why the page footer wouldn't expand as the content grew. I got that sorted out but now the footer moves south but a page scrollbar never shows up.

我的UiBinder xml如下(这是一个

My UiBinder xml is as follows (here's a link to the file):

<g:DockLayoutPanel unit='PX' styleName="{style.shellStyles.wrap}">
<g:north size='180'>
    <g:HTMLPanel styleName='{style.shellStyles.header}'>
        <div id="login" class="{style.shellStyles.login}">
            <g:InlineLabel ui:field="loggedInUser"/>
            <g:InlineHyperlink ui:field="loginLogoutLink"/>
        </div>
        <h1><a href="/">Flash Cards Application</a></h1>
    </g:HTMLPanel>
</g:north>
<g:center>
  <g:FlowPanel>
    <g:HTMLPanel styleName='{style.shellStyles.content}'>

        <g:SimplePanel styleName='{style.shellStyles.right}' ui:field='contentPanel' />
        <div style="clear: both;" ></div>
