Notepad++ plugin(插件)开发之消息HOOK (文件保存，文件打开，文件关闭)

Notepad++ plugin(插件)开发之消息HOOK (文件保存，文件打开，文件关闭)

Notepad++ 插件 开发(上一篇关于 notepad++ plugin（插件开发）的文章)

(找了比较久才发现，记录一下 IS2120

1. 在notepad++提供了一些hook消息，能够 用于通知plugin一些消息，诸如

文件的打开，文件的保存等

2. 如何利用这些消息（使用c++开发）
在开发plugin时会有一些必须的函数。其中之一是
typedef void (__cdecl * PBENOTIFIED)(SCNotification *);
void __cdeclbeNotified(struct SCNotification *notifyCode);
这个函数在编辑文件的时候总是会被调用。

可以在这个函数里获取这些通知消息，完成自己想做的事情。

3. 文件的打开 (NPPN_FILEOPENED)

这个消息只能提示你一个文件打开了，但是不能告知你文件是否载入好了。

可以通过使用 NPPN_BUFFERACTIVATED 来提示文件文件已经载入，但是这个与FILEOPENED并不一样。

NPPN_FILEOPENED sends a BufferID which a plugin should transparently use to retrieve information about a file, but not its contents.
