NAME

6       Gtk2::Window - wrapper for GtkWindow
7

DESCRIPTION

9       A Gtk2::Window is a top-level window displayed on the root window and
10       interacting (or not) with the window manager.  It can be an
11       application's main window, a dialog, or a temporary such as a popup
12       splash window.
13
14   Delete Event and Destroy
15       The default action for a "delete-event" (normally from the window
16       manager close button) is to destroy the window with "$window->destroy".
17       In your main window you might want to exit the main loop when that
18       happens.
19
20           $toplevel->signal_connect (destroy => sub { Gtk2->main_quit });
21
22       If you install a handler for "delete-event" and return true, meaning
23       "don't propagate", you can do something other than destroy the window.
24       For example
25
26           $toplevel->signal_connect (delete_event => sub {
27              if (any_unsaved_documents()) {
28                popup_ask_save_before_exit_dialog();
29                return Gtk2::EVENT_STOP;  # don't go to default destroy
30              } else {
31                return Gtk2::EVENT_PROPAGATE;
32              }
33           });
34
35       In a dialog or secondary app window you might not want to destroy but
36       instead just hide ready for later re-use.
37
38           $dialog->signal_connect
39             (delete_event => \&Gtk2::Widget::hide_on_delete);
40
41       The choice between destroying or hiding is normally just a matter of
42       memory saved against the time to re-create, and how likely the dialog
43       might be needed again.  (However if you build windows with Glade it's
44       not particularly easy to re-create them there, so you'll mostly want to
45       just hide in that case.)
46
47       A hidden toplevel window is still in "Gtk2::Window->list_toplevels" and
48       that's a good place to search for an existing window of a desired type
49       to "$window->present" again.

245       •   ... (list) of Gtk2::Gdk::Pixbuf's
246
247       Sets up the icon representing a Gtk2::Window. The icon is used when the
248       window is minimized (also known as iconified). Some window managers or
249       desktop environments may also place it in the window frame, or display
250       it in other contexts.
251
252       set_icon_list () allows you to pass in the same icon in several hand-
253       drawn sizes. The list should contain the natural sizes your icon is
254       available in; that is, don't scale the image before passing it to GTK+.
255       Scaling is postponed until the last minute, when the desired final size
256       is known, to allow best quality.
257
258       By passing several sizes, you may improve the final image quality of
259       the icon, by reducing or eliminating automatic image scaling.
260
261       Recommended sizes to provide: 16x16, 32x32, 48x48 at minimum, and
262       larger images (64x64, 128x128) if you have them.
