GWT：TabPanelLayoutPanel隱藏或顯示Tabbaritems

Question

有沒有辦法隱藏/在TablayoutPanel顯示的TabBar項目

Answer 1

調用setVisible將只設置樣式屬性顯示到沒有。所以，你可以創建自己的API這樣，

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)); 
}-*/;
