           Summary: [GTK] On-demand event-listeners for DOM event signals
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: cgarcia at igalia.com


GLib signals are currently used to implement events in GObject DOM bindings. Since it's not possible to know what signals the user is going to connect, an event listener is added in every node for every signal when object is constructed. Xan proposed two possible solutions: modify glib/gobject to add a way to notify the user when a signal is connected/disconnected, or add api to webkit dom bindings so that the user can add event listeners, something like webkit_dom_event_target_add_event_listener (target, listener);
Second option is less GObject-y, so the preferred solution is the first one although it depends on whether a patch for this is accepted in gobject.
