Question

我正在开发一个小型应用程序。我想修改WebKit Webview的默认上下文菜单。具体来说，我想

阻止/隐藏上下文菜单
将项目添加到上下文菜单
从上下文菜单中删除项目
从上下文菜单中删除所有项目

我正在寻找解决方案

Python 2和WebKit
Python 3和WebKit2

Python 2和WebKit

有效方法：

将项目添加到上下文菜单

什么不起作用：

从上下文菜单中删除项目
从上下文菜单中删除所有项目

代码：

#!/usr/bin/python
# -*- coding: utf-8 -*-

from gi.repository import Gtk, WebKit

class MyWindow(Gtk.Window):

    def __init__(self, *args):

        Gtk.Window.__init__(self, title="test")

        self.wv = WebKit.WebView()
        self.add(self.wv)

        # add item
        def append_item(webview, context_menu, hit_result_event, event):
            option = Gtk.ImageMenuItem('Extra')
            context_menu.append(option)
            option.show()

        # select case, change this to "1", "2" etc.
        x = 0

        # block/hide context menu
        if x == 1:
            settings = self.wv.get_settings()
            settings.set_property('enable-default-context-menu', False)
        # add item
        elif x == 2:
            self.wv.connect('context-menu', append_item)
        # remove item
        # ???
        # remove all items
        # ???

win = MyWindow()
win.show_all()
Gtk.main()
