寫在前面:
下面的這段代碼可以直接在LuaForWindows的Scite中運行,這個函數(shù)的是仿照LuaForWindows自帶教程中的那個創(chuàng)建iup菜單的函數(shù)寫的,改進(jìn)的一個地方是可以用一個消息處理回調(diào)函數(shù)來響應(yīng)多個菜單項,然后再統(tǒng)一dispatch,個人認(rèn)為寫法上比直接把進(jìn)行實際處理的函數(shù)寫在菜單定義表前面美觀一些,
說來慚愧,就改寫的這個小函數(shù),也是調(diào)試了一大會才弄好的,剛接觸Lua的時候,就是不熟練啊...(廢話? !)

后記,已經(jīng)發(fā)布在了我的粘貼里,不過它上面說是根據(jù)時間訪問來刪除舊帖子的,我怕時間久了這點記憶再沒有了
