            self.Bind(wx.EVT_MENU, self.OnPopupProperty, id = self.popupPropery)

        # 创建菜单
        menu = wx.Menu()
        itemStop = wx.MenuItem(menu, self.popupStop, "Stop")
        itemProperty = wx.MenuItem(menu, self.popupPropery, 'Property')

        menu.AppendItem(itemStop)
        menu.AppendItem(itemProperty)

        itemProperty.Enable(False)#默认让属性按钮变成无效状态

        if itemid == -1:#如果没有选中任何项
            itemStop.Enable(False)
        else:
            itemStop.Enable(False)
            itemProperty.Enable(True)
        #到这里才弹出菜单
        self.PopupMenu(menu)
        #最后注意销毁前面创建的菜单
        menu.Destroy()

5. 选择文件对话框(FileDialog)

使用起来非常简单：

dlg = wx.FileDialog(self,
                            message="Yes, select a place ",
                            wildcard="PNG(*.png)|*.png" ,
                            style=wx.SAVE
                            )
        savefile = ''
        if dlg.ShowModal() == wx.ID_OK:
            savefile = dlg.GetPath()
            try:
                os.remove(self.filename)
            except:
                pass
            self.img.SaveFile(savefile, wx.BITMAP_TYPE_PNG)
            self.filename = savefile
