Hi guys, I think that it's a good thing forward the following email here! Ciao Luca
---------- Forwarded message ---------- From: Boris 'billiob' Faure <bill...@gmail.com> Date: Sun, Nov 22, 2009 at 10:28 PM Subject: [E-devel] Important change in python elementary To: enlightenment-de...@lists.sourceforge.net I've committed some changes to how callbacks are handled in python elementary. If you use it, your application is now broken, I'm sorry. However, it's better now than letter :) So, what have changed? You used to bind a callback to the "clicked" of a button this way: bt.clicked = my_func or bt.clicked = (my_func, my_data) The signature of the callback was always: my_func(obj, event, data) even if you had not set any data! What if you wanted to perform 2 actions? How could you remove the callback? Now, in order to connect a function to an event, let say 'clicked', you use: bt.callback_clicked_add(func, *args, **kwargs) The required signature is my_func(obj, *args, **kwargs) or my_func(obj, it, *args, **kwargs) if an item is given, for example when an item in a toolbar is clicked. If you want to disconnect this function to the event, you call: bt.callback_clicked_remove(func, *args, **kwargs) if func is None, all the events bound to 'clicked' are removed. args and kwargs must be the same as those given when the callback was set. Now, this is possible: def destroy(win, str1, str2, str3, str4): print :str1='%s', str2='%s', str3='%s', str4='%s'" %( str1, str2, str3, str4) win.callback_destroy_add(destroy, "test1", "test2", str3="test3", str4="test4") To sum up: when you used: obj.EVENT = XXX now you should use: obj.callback_EVENT_add(XXX) I've updated the testing file. I hope to have patched correctly editje. -- Boris 'billiob' Faure ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
