Eclipse插件RCP桌面應(yīng)用開發(fā)的點(diǎn)點(diǎn)滴滴 _生活百科

Eclipse插件開發(fā)的點(diǎn)點(diǎn)滴滴新公司做的是桌面應(yīng)用程序，與之前一直在做的web頁面，相差甚大。這篇文章是寫于2022年10月底，這時(shí)在新公司已經(jīng)入職了快三月。寫作目的是：國內(nèi)對(duì)于eclipse插件開發(fā)相關(guān)的文檔是少之又少，這三個(gè)月我們小組翻遍了國外文檔，勉強(qiáng)將軟件拼湊出并release出測(cè)試版本，為了方便同行以及自我學(xué)習(xí)，所以想把這幾個(gè)月學(xué)到的eclipse rcp插件相關(guān)知識(shí)寫下來。
一、 Wizard部分Wizard 一般用于向?qū)綄?duì)話框，eclipse的新建項(xiàng)目就是一個(gè)典型的wizard。wizard一般由幾個(gè)wizard page 組成，通過按鈕控制上一頁下一頁完成取消。

①自定義wizardpage主要是繼承JFACE 的 WizardPage ,并重寫 createControl方法。在createControl方法中，可以對(duì)你的向?qū)ы撁娼M件進(jìn)行布局、添加監(jiān)聽等動(dòng)作。②對(duì)于當(dāng)前頁面的標(biāo)題、描述等信息，可以在構(gòu)造函數(shù)中通過setTitle 和 setDescription方法來設(shè)置
