Re: [Java-gnome-developer] error defining signals with glade

[Keith I. <ke...@ke...>]

I think the method needs to be void:

  public void on_button1_clicked() {
    System.out.println("clicked");
  }

If you check out the tutorial on the java-gnome site, I think it
explicitly says this somewhere.
