I think the best thing you can do is associate a number when you connect the button response to a method like this:
my_button.signal_clicked().connect(sigc::bind(sigc::mem_fun(*this, &my_class::OnMyButtonClicked),iNumber)); The only thing you have to take into account is that the response method changes from the standard one. If the method to be associated to a click event of a button is the following: void on_my_clicked() When you use sigc::bind the method changes and it should be like this void OnMyButtonClicked(int x) I hope this helps you, Kind regards, Jon Zabala > Date: Mon, 28 Oct 2013 17:29:18 +0200 > From: fr33domlo...@mailoo.org > To: gtk-app-devel-list@gnome.org > Subject: Re: Signal of a button dynamically created > > > > I'm not experienced but here's a quick idea: > > Create a new derived Button class which handles its own click by > overriding the virtual method, and in that method it emits a signal > which passes the button ID/row number as a parameter.
