我正在尝试实现一个简单的对话框.我想要确定并取消对话框底部对齐的按钮.我将按钮嵌入Horizo​​ntalPanel并尝试将水平对齐设置为RIGHT.但是,这不起作用.如何使按钮对齐？谢谢.这是片段:

private Widget createButtonsPanel() {
    HorizontalPanel hp = new HorizontalPanel();
    hp.setCellHorizontalAlignment(saveButton, HasHorizontalAlignment.ALIGN_RIGHT);
    hp.setCellHorizontalAlignment(cancelButton, HasHorizontalAlignment.ALIGN_RIGHT);
    hp.add(saveButton);
    hp.add(cancelButton);       

    return hp;
}
