You should write return true

You should write return true

Yeah, I forget write it, but this is a example. If the ActionBeforeClose not called, it's meaningless no matter return true or not. The return value just for determine it to close or not.

@NaBian Hi, I found that if clear by right click context menu, the ActionBeforeClose also not called. Does commit a6a78f4 also fix this?
