I don't remember the technical reason this could not be implemented. I
found a way to emulate this behavior using a dictionary and delegation.
Here's a silly example:
----------------------------------------8<---------------------------
from gtk import *
class TwoButtons(GtkHBox):
def __init__(self, label1, label2):
GtkHBox.__init__(self)
button = GtkButton(label1)
toggle = GtkToggleButton(label2)
self.pack_start(button)
self.pack_start(toggle)
self._signalmap = {"hello" : (button, "clicked"),
"howdy" : (toggle, "toggled") }
def show(self):
for obj, signal in self._signalmap.values():
obj.show()
GtkHBox.show(self)
def connect(self, new_signal, callback, *extra):
if self._signalmap.has_key(new_signal):
object, signal = self._signalmap[new_signal]
apply(object.connect, (signal, callback) + extra)
else:
apply(GtkHBox.connect, (self, new_signal, callback) + extra)
def howdy(*args):
print args
print "Howdy!"
def hello(*args):
print args
print "Hello!"
def welcome(*args):
print args
print "Welcome!"
win = GtkWindow()
win.connect("delete-event", mainquit)
buttons = TwoButtons("Howdy", "Hello")
buttons.connect("howdy", howdy)
buttons.connect("hello", hello)
buttons.connect("show", welcome)
win.add(buttons)
buttons.show()
win.show()
mainloop()
