如何向添加其他参数按钮连接在PyGTK？

Question

我想把2个ComboBox实例传递给a方法并在那里使用它们（例如，打印它们的活动选择）。我有一些类似的东西：

class GUI():
  ...

  def gui(self):
    ...
    combobox1 = gtk.combo_box_new_text()
    # code for inserting some values into the combobox
    combobox2 = gtk.combo_box_new_text()
    # code for inserting some values into the combobox
    btn_new = gtk.Button("new")
    btn_new.connect("clicked", self.comboprint)

  def comboprint(self):
    # do something with the comboboxes - print what is selected, etc.

如何将combobox1和combobox2传递给方法“comboprint”，以便在那里使用它们？使它们成为类域(自我组合框1, 自我组合框2)唯一的办法是？在

我会用另一种方法来解决这个问题，通过创建combbox1和combobox2类变量，如下所示：

class GUI():
  ...

  def gui(self):
    ...
    self.combobox1 = gtk.combo_box_new_text()
    # code for inserting some values into the combobox
    self.combobox2 = gtk.combo_box_new_text()
    # code for inserting some values into the combobox
    btn_new = gtk.Button("new")
    btn_new.connect("clicked", self.comboprint)

  def comboprint(self):
    # do something with the comboboxes - print what is selected, etc.
    self.combobox1.do_something

这样做的好处是，当另一个函数需要处理这些组合框时，它们可以这样做，而不必将组合框作为参数传递给每个函数。在

做这样的事情：

btn_new.connect("clicked", self.comboprint, combobox1, combobox2)

在你的回调中comboprint应该是这样的：
