Ok, I'm trying with the signal, but I get a lot of errors.

where's what I'm doing:

my class inherits from Gtk::Window.

then on the constructor I have,
this->signal_key_release_event().connect ( sigc::mem_fun(*this,
&AnimeWindow::onKeyRelease) );

(here, I don't know if I have to send an argument?..)

and then my function:

void AnimeWindow::onKeyRelease(GdkEventButton *event)
{
cout << "key" << endl;
}

Hi,

signal_key_release_event() seems the right way to do it. For the list of key
values, see gdk/gdkkeysyms.h as stated in Gtk's documentation :
http://developer.gnome.org/gdk/stable/gdk-Event-Structures.html#GdkEventKey

You could also derivate your class from Gtk::Dialog, which recieves a
response when ESC is pressed.

Hey, I have a window which I want to close when the esc key is
pressed, I've tried overriding the "virtual bool on_key_release_event
(GdkEventKey* event); " but I get some weird errors (also can't find
the documentation about GdkEventKey, to identify the keys). I tried
adding a function to the "signal_key_release_event()" but also get
some errors :)

Can anyone tell me how to call a function when the esc key is pressed
(on a Gtk::Window derived class)?

on_key_rlease_event() must return bool instead of void:

bool AnimeWindow::onKeyRelease(GdkEventButton *event)
{
cout << "key" << endl;
return true;
}
