Eclipse插件RCP桌面应用开发的点点滴滴 _生活百科

Eclipse插件开发的点点滴滴新公司做的是桌面应用程序，与之前一直在做的web页面，相差甚大。这篇文章是写于2022年10月底，这时在新公司已经入职了快三月。写作目的是：国内对于eclipse插件开发相关的文档是少之又少，这三个月我们小组翻遍了国外文档，勉强将软件拼凑出并release出测试版本，为了方便同行以及自我学习，所以想把这几个月学到的eclipse rcp插件相关知识写下来。
一、 Wizard部分Wizard 一般用于向导式对话框，eclipse的新建项目就是一个典型的wizard。wizard一般由几个wizard page 组成，通过按钮控制上一页下一页完成取消。

①自定义wizardpage主要是继承JFACE 的 WizardPage ,并重写 createControl方法。在createControl方法中，可以对你的向导页面组件进行布局、添加监听等动作。②对于当前页面的标题、描述等信息，可以在构造函数中通过setTitle 和 setDescription方法来设置
