GWT：TabPanelLayoutPanel隐藏或显示Tabbaritems

Question

有没有办法隐藏/在TablayoutPanel显示的TabBar项目

Answer 1

调用setVisible将只设置样式属性显示到没有。所以，你可以创建自己的API这样，

public void hideTabItem (Widget tabItem, boolean hideFl) 
{ 
    hideTabItem (tabItem.getElement(), hideFl); 
         OR 
    tabItem.setVisible (hideFl); 
} 

private static native void hideTabItem (Element elem, boolean visible) 
/*-{ 
    elem.style.display = visible ? '' : 'none'; 
    elem.setAttribute('aria-hidden', String(!visible)); 
}-*/;
