包装GWT对话框的页脚

Question

DialogBox is in fact set of <div> elements. There is basically TitleBar, MainContent and the Footer. By default adding elements to DialogBox will throw them into main Content.

What I want is to throw something into footer. Its basically this div: <div class="dialogBottomCenterInner">

I made this method inside the class that inherits from DialogBox to wrap the footer:

public HTMLPanel getFooter() {
    Element td = getCellElement(2, 1);
    td.setId("footer"); //html at this point = <div class="dialogBottomCenterInner" id="footer"></div>              
    HTMLPanel panel = HTMLPanel.wrap(td);
    return panel;
}

Unfortunatelly it fails at HTMLPanel.wrap(td); with java.lang.AssertionError: null

Answer 1

There is no footer in a DialogBox. The element you refer to is a part of a border that surrounds the DialogBox.
