			GUI學(xué)生成績(jī)管理系統(tǒng)
		
    
		
    這個(gè)程序終于完完整整地做完了，雖然還不完善，但基本的功能實(shí)現(xiàn)了。這個(gè)程序零零散散花費(fèi)了我近一個(gè)月的時(shí)間，在這一個(gè)月的時(shí)間里，通過別人的幫助和對(duì)程序的調(diào)試本人收獲不小。希望通過這個(gè)博客和大家分享一下我在程序中犯的錯(cuò)誤。
    

    1.其實(shí)用SWT做東西，基本的組件什么的都挺容易，難的是兩個(gè)或多個(gè)面板的調(diào)用（我想這就是面向?qū)ο笏枷氚桑．?dāng)調(diào)用另一個(gè)Display時(shí)，一定要通過參數(shù)將主程序中的display傳遞到另一個(gè)程序中，然后在另一個(gè)程序用構(gòu)造函數(shù)接受傳遞過來(lái)的display。
    

    2.在用按鈕調(diào)用另一個(gè)面板時(shí)，一定不要將面板設(shè)置為static類型的，否則第二次點(diǎn)擊這個(gè)按鈕時(shí)將會(huì)出錯(cuò)。
    

    3.不管是主程序還是其它程序一定要有shell.open()，即將面板打開
    

    4.在非主程序中還要有shell.close()即將面板關(guān)閉
    

    下面看這個(gè)程序的要求：
    

    要求：
    

    1.實(shí)現(xiàn)增、刪、改、查功能
    

    2.使用SWT進(jìn)行界面管理
    

    下面大致的看一下這個(gè)程序的運(yùn)行效果。
    

    1、初次運(yùn)行界面：
    

    未命名 
    

    2、選擇添加按鈕：
    

    未命名 
    

    輸入信息，如果信息輸入格式不正確：
    

    未命名 
    

    輸入正確的信息，就會(huì)添加到表格中。
    

    3、選擇刪除按鈕前，必須選中一條或多條信息，否則會(huì)出現(xiàn)：
    

    未命名 
    

    選擇將要?jiǎng)h除的學(xué)生信息，點(diǎn)擊刪除按鈕就會(huì)將改學(xué)生的信息在表格中刪除。
    

    4、選擇修改按鈕前，也必須選中一條信息，否則會(huì)出現(xiàn)：
    

    未命名 
    

    選中信息后，點(diǎn)擊修改按鈕，就會(huì)出現(xiàn)修改學(xué)生信息窗口：
    

    未命名 
    

    將信息修改后，點(diǎn)擊確定按鈕就會(huì)將原先的信息覆蓋并顯示在表格中
    

    5、選擇查詢按鈕，就會(huì)出現(xiàn)：
    

    未命名 
    

    可以通過學(xué)號(hào)、姓名、成績(jī)、班級(jí)或者他們中的任意一項(xiàng)或幾項(xiàng)進(jìn)行查詢，如果一項(xiàng)都不寫將出現(xiàn)：
    

    未命名 
    

    如果沒有您要查詢的信息，將出現(xiàn)：
    

    未命名 
    

    如果有您的信息，那么這個(gè)信息在表格中將以綠色顯示：
    

    未命名 
    

    這個(gè)程序還有許多要修改的地方。
