Fixed Container故名之意就是固定容器，它容許把控件放到一個(gè)固定容器中，并能隨意到移動(dòng)到某個(gè)位置［相對(duì)于窗口的左上方］。雖然它能隨意移動(dòng)，但有很多弊端，比如容器的大小它會(huì)隨字體的大小的改變而改變，從而可能會(huì)出現(xiàn)控件覆蓋控件的現(xiàn)象；又如在多語(yǔ)言中，我們都知道阿拉伯語(yǔ)到單詞大部分都比E文單詞都要長(zhǎng)，如果從E語(yǔ)切換到阿拉伯語(yǔ)或其它語(yǔ)言時(shí)，固定容器的在水平方向?qū)?huì)發(fā)生伸縮等現(xiàn)象明顯是用戶(hù)所不能接受的。所以不推薦使用fixed container。下面是一個(gè)對(duì)Fixed Container的簡(jiǎn)單實(shí)例：/**********************************

}Exapnder有擴(kuò)展之意，expander容器只允許有一個(gè)子控件，通過(guò)點(diǎn)擊expander容器可以伸展或隱藏其子控件。以下是一個(gè)對(duì)Expander的簡(jiǎn)單實(shí)例：
