Hello everyone, I'm still playing around with Vala and GTK+, and trying to port my little application to this language.
Today I experimented with key bindings, but I encountered a problem I'm not
able to solve. The following code
using GLib;
class BindingTest : Gtk.Window {
public signal void do_something ();
public BindingTest () {}
construct {
title = "Binding Test";
set_default_size (200, 150);
Gtk.Label label = new Gtk.Label ("Control-d does something.");
add (label);
delete_event += Gtk.main_quit;
do_something += () => { stdout.printf ("Done something.\n"); };
}
public static int main (string[] args) {
Gtk.init (ref args);
Gtk.rc_parse_string ("binding \"Test\" {" +
" bind \"<control>d\" {" +
" \"do_something\" ()" +
" }" +
"}" +
"class \"BindingTest\" binding \"Test\"");
BindingTest window = new BindingTest ();
window.show_all ();
Gtk.main ();
return 0;
}
}
compiles and runs perfectly, but when I press Control-d I get the following
warning message,
(bindingtest:9485): Gtk-WARNING **: gtk_binding_entry_activate():
binding "TestBinding::<Control>d": signal "do_something" in the
`BindingTest' class ancestry cannot be used for action emissions
which is caused by the fact that the do_something signal is not declared
as an action signal (G_SIGNAL_ACTION) in the generated C file, and as such
GTK+ refuses to emit it directly.
Is there any way to declare a signal as an action signal? I grep'd a bit
around the valac source code but I couldn't find anything.

Resistance is futile, you will be garbage collected.
