Hi,
can anyone explain me how does the Gtk.Builder.connect_signals() method
works?
You can read in guide (http://live.gnome.org/Vala/GTKSample) that when we
want to connect signals with method of instanced object then we have to
annotate the method with [CCode (instance_pos = -1)] and pass pointer to the
object to connect_signal(pointer).
Ok, that works, but why it works as well when I neither annotate my method
nor pass the pointer?
The code below actually works but according to all guides it shouldn't. Why?
class TestApp {
public TestApp() {
try {
this.builder = new Gtk.Builder ();
builder.add_from_file("../ui/interface.glade");
builder.connect_signals(null);
} catch (Error e) {
stderr.printf("Could not load UI: %s\n", e.message);
}
}
public void on_close() {
stdout.printf("Quit application\n");
Gtk.main_quit();
}
}
Thanks,
Pawel
