在使用python的nautilus扩展中使用gtk

以下代码

import gtk
import nautilus
import os
def alert(message):
    """A function to debug"""
    dialog = gtk.MessageDialog(None, gtk.DIALOG_MODAL, gtk.MESSAGE_INFO, gtk.BUTTONS_CLOSE, message)
    dialog.run()
    dialog.destroy()

class TestExtension(nautilus.MenuProvider):
    def __init__(self):
        pass

    def get_file_items(self, window, files):
        items = []
        """Called when the user selects a file in Nautilus."""
        item = nautilus.MenuItem("NautilusPython::test_item", "Test", "Test")
        item.connect("activate", self.menu_activate_cb, files)
        items.append(item)
        return items

    def menu_activate_cb(self, menu, files):
        """Called when the user selects the menu."""
        for name in files:
            alert(name)

然而

import easygui
import nautilus
import os

def alert(message):
    """A function to debug"""
    easygui.msgbox(message)

class TestExtension(nautilus.MenuProvider):
    def __init__(self):
        pass

    def get_file_items(self, window, files):
        items = []
        """Called when the user selects a file in Nautilus."""
        item = nautilus.MenuItem("NautilusPython::test_item", "Test", "Test")
        item.connect("activate", self.menu_activate_cb, files)
        items.append(item)
        return items

    def menu_activate_cb(self, menu, files):
        """Called when the user selects the menu."""
        for name in files:
            alert(name)

(更好的是,在将alert()移动到 get_file_items() 信息显示正确)
