GXT:UiBinder小部件的新实例 [英] GXT: UiBinder new instance of a Widget

问题描述

我在窗口内有一个TextField表单.用UiBinding创建.在TextField旁边是一个按钮.我想知道当使用UiBinder按下该按钮时是否可以创建一个新的TextField小部件吗?

I have a TextField form inside a window. Created with UiBinding. Next to the TextField is a button. I wanted to know if it was possible to create a new TextField widget when that button was pressed using UiBinder?

这就是我所拥有的:

窗口类:

@UiField
TextField text;

@UiField
HorizontalPanel hPanel;
....
@UiHandler("addText")
public void onClick(SelectEvent event){
      hPanel.add(text);
}

我的UiBinder文件:

My UiBinder file:

<gxt:Window ...(generic setup)...>
 <g:VerticalPanel>
  <gxt:FramedPanel>
   <container:VericalLayoutContainer>
    <container:child>
     <g:HorizontalPanel ui:field="hPanel">
      <form:FieldLabel text="Text">
       <form:Widget>
        <form:TextField ui:field="text"/>
       </form:Widget>
      </form:FieldLabel>
      <button:TextButton ui:field="addText"/>
     </g:HorizontalPanel>
    </container:child>
   </container:VericalLayoutContainer>
  </gxt:FramedPanel>
 </g:VerticalPanel>
</gxt:Window>

当我单击按钮时，所要做的就是将按钮从文本字段的右侧移至左侧.我在窗口中有更多的文本字段，所以我四处游玩以查看它的实际作用.它占用了该字段并将其移动到按钮旁边.

When I click the button it all it does is move the button from the right side of the text field to the left. I have more textfields in the window so I played around to see what it was really doing. It's taking that field and just moving it next to the button.

有没有办法在原始文本下方创建一个新的TextField?

Is there a way I can create a new TextField underneath the original?
