做组织机构树状图 spark

發(fā)布時間：2025/3/20 编程问答 44 豆豆

生活随笔收集整理的這篇文章主要介紹了做组织机构树状图 spark 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

很簡單基本上就是復(fù)制粘貼再做兩個圖片 OK了

摘自： http://hi.baidu.com/awol2005ex/item/8c673626e8ff493194f62bd0

然后在spark?加一個插件用于展示組織機構(gòu),?參考了好多人的代碼?

插件主類增加一個?TAB用于展示機構(gòu)樹

package??com.salesoa.orgtree; import?java.net.URL;
//展示OA的組織結(jié)構(gòu) public?class?OrgTreePlugin?implements?Plugin{
????private?static?ImageIcon??organ_icon=null; ???? ????public?static?ImageIcon????getOrganIcon(){//機構(gòu)圖標(biāo) ????????if(organ_icon==null){ ????????????ClassLoader??cl=OrgTreePlugin.class.getClassLoader(); ????????????URL???imageURL=cl.getResource("images/organ.gif"); ????????????organ_icon=new???ImageIcon(imageURL); ????????} ????????return??organ_icon; ????} ???? ????private?static?ImageIcon??user_icon=null; ???? ????public??????????static????ImageIcon?????getUserIcon(){//機構(gòu)圖標(biāo) ????????if(user_icon==null){ ????????????ClassLoader????cl=OrgTreePlugin.class.getClassLoader(); ????????????URL??imageURL=cl.getResource("images/user.gif"); ????????????user_icon=new???ImageIcon(imageURL); ????????} ????????return?user_icon; ????} ???? ????@Override ????public?void?initialize()?{ ????????//?TODO?Auto-generated?method?stub ????????Workspace??workspace=SparkManager.getWorkspace();
????????SparkTabbedPane???tabbedPane=workspace.getWorkspacePane();
????????OrgTree???orgTreePanel=newOrgTree();//機構(gòu)樹
???????? ???????? ????????//?Add?own?Tab. ????????tabbedPane.addTab("組織架構(gòu)",OrgTreePlugin.getOrganIcon(),orgTreePanel); ????}
????@Override ????public?void?shutdown()?{ ????????//?TODO?Auto-generated?method?stub
????}
????//?是否可關(guān)閉 ????@Override ????public?boolean?canShutDown()?{ ????????//?TODO?Auto-generated?method?stub ????????return?false; ????}
????//?卸載 ????@Override ????public?void?uninstall()?{ ????????//?TODO?Auto-generated?method?stub
????}
}
