Python gtk.entry()图标连接:是否可能

Question

我在Pygtk 2.7中使用gtk.Entry。我已经设置了一个图标，我想知道是否有可能将图标连接到一个功能。我的结构是这样的:

    def info(self, a, b):
        print "INFOS & HELP"
    def __init__(self):
        window = gtk.window(gtk.WINDOW_TOPLEVEL)
        #[...]     
        self.champ_adr_canal = gtk.Entry()
        self.champ_adr_canal.connect("activate", self.download, self.champ_adr_canal)
        self.champ_adr_canal.set_text("")
        boite_adr.pack_start(self.champ_adr_canal, False, True, 0)
        self.champ_adr_canal.set_icon_from_stock(1, gtk.STOCK_DIALOG_QUESTION) # the icon is here
        ### this line is a pseudo code ####
        self.champ_adr_canal.connect("clicked", self.info, "bouton info") # how can I do this? 
        ###                            ####
        self.champ_adr_canal.show()

谢谢!

根据文档，您需要使图标可激活并连接到icon-press或icon-release信号:

self.champ_adr_canal.set_icon_activatable(1, True)
self.champ_adr_canal.connect("icon-release", self.info)
