Question

I want to pass 2 ComboBox instances to a a method and use them there (e.g., print their active selection). I have something similar to the following:

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.

How can I pass combobox1 and combobox2 to the method “comboprint”, so that I can use them there? Is making them class fields (self.combobox1, self.combobox2) the only way to do this?

Answer 1

do something like this:

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

and in your callback comboprint it should be something like this:

def comboprint(self, widget, *data):
    # Widget = btn_new
    # data = [clicked_event, combobox1, combobox2]
    ...
