python - Can Gedit plugins bind to the OnSave event?

Question

I'm writing a gedit 3 plugin, something similar to phsilva's PyLint plugin, which calls out to an external lint program and highlights lines of code in the current document. My question is, if my plugin has a run_lint action is it possible to bind that to the OnSave event in gedit? The list of available signals in the documentation I've linked above still has a FIXME notice against it and I'm struggling to figure out where in the soup of API documentation the full list can be found.

好吧，没有人回答这个问题，但我最终想通了。这有两个步骤，当在该选项卡包含文档的窗口中创建一个新选项卡时。该文档具有可以连接到操作的信号loaded。saved重要的是要记住每个选项卡都有一个单独的文档，每个文档都需要自己的一组信号和处理程序。

这是一个大纲解决方案，以防对其他人有用：

class FooPlugin(GObject.Object, Gedit.WindowActivatable):

    __gtype_name__ = 'Foo'
    ...

    def do_activate(self):
        self._add_ui()
        self.window.connect('tab-added', self.on_tab_added)
        ...
        return

    def on_tab_added(self, window, tab, data=None):
        doc = tab.get_document()
        doc.connect('saved', self.on_document_saved)
        doc.connect('loaded', self.on_document_loaded)
        return

    def on_document_loaded(self, document, data=None):
        # do something here...
        return

    def on_document_saved(self, document, data=None):
        # do something here...
        return
