我想知道是否有可能在GWT页面的最底部有一个TabLayoutPanel,遗憾的是网上的文档很少。

是的,这是可能的。最简单的方法是使用DockLayoutPanel区域。您应该将TabLayoutPanel包装在另一个LayoutPanel中,以确保您的内容正确显示,否则您必须为TabLayoutPanel添加高度。我从内存中输入了这个,但语法应该是正确的。
<DockLayoutPanel unit="PX">
<g:south size="200">
<g:TabLayoutPanel barHeight="30" barUnit="PX">
<g:tab>
<g:header>Tab 1</g:header>
<g:Label> Tab 1 content</g:Label>
</g:tab>
<g:tab>
<g:header>Tab 2</g:header>
<g:Label>Tab 2 content</g:Label>
</g:tab>
</g:TabLayoutPanel>
</g:south>
<g:center>
<g:FlowPanel>
<g:Label>Main page content</g:Label>
</g:FlowPanel>
<g:center>
</DockLayoutPanel>

不是很优雅,但它有效:
public class BottomLabLayoutPanel extends TabLayoutPanel
{
public BottomLabLayoutPanel(double barHeight, Unit barUnit)
{
super(barHeight, barUnit);
LayoutPanel panel = (LayoutPanel)getWidget();
if (panel.getWidgetCount() >= 2)
{
Widget w1 = panel.getWidget(0);
Widget w2 = panel.getWidget(1);
Element e1 = w1.getElement().getParentElement();
Element e2 = w2.getElement().getParentElement();
if (e1 != null)
e1.setClassName("BottomTabLayoutPanel TabPanel");
if (e2 != null)
e2.setClassName("BottomTabLayoutPanel ContentPanel");
}
}
}
在CSS中:
.BottomTabLayoutPanel.TabPanel
{
top: auto !important;
bottom: 0px !important;
}
.BottomTabLayoutPanel.ContentPanel
{
top: 0px !important;
margin-bottom: 35px !important;
}
