        Window : Gtk.Window.Gtk_Window;
begin
        Gtk.Window.Gtk_New (Window);

        Gtk.Window.Show_All (Window);
        Gtk.Main.Main;


it displays the Window
it's right, but it waits for Main_Quit, and i don't want that

if i comment Show_All, it doesn't display the Window
it's right

but if i comment Main instead, it doesn't display the Window more !
why ?


how can i do, please ?

Create the window as popup window using Gtk.Enums.Window_Popup and then
register a simple "Destroy" procedure with Glib.Main.Timeout_Add that
closes the window after the time you want.

in fact Window_Popup doesn't works for my problem

(it is very specific :
http://groups.google.fr/group/fr.comp.os.mac-os.x/browse_thread/ 
thread/3985c57539a57636/3df9d9564ea8ede3
i try to make a little program which open a windows an then quit, as  
fast as possible)


maybe it would work if i use Glib.Main.Timeout_Add to call Main_Quit

could you help me to do that, please ?
i don't understand all the arguments, and i don't know what i should put

I'm sorry, those messages are in French and although I learnt French at
school, it's too tedious for me to translate them. And I didn't see any
references to GtkAda.

And I still don't understand what you want to do. We use this mechanism
in order to display a splash screen for a certain amount of time during
the start of our application. I do not see why one could not make this
stand-alone without any further payload.

i suppose you don't know mac os x too, and i don't want annoy you  
with things you don't care,

to circumvent a bug from mac os x's x11,
i need to make a little program which open a window (without anything  
inside) and then quit (at once)
(i want to use GtkAda to make this program because i don't know  
programming in c)

is it clear enough ?

well, it doesn't works with Window_Popup, i need to use a  
Window_Toplevel
and i don't know how to use Glib.Main.Timeout_Add at all, i never  
used it

I can't deduce this from your desciption of what you need.

bellonsn@cube$ cat splashdemo.adb
with Glib.Main;
with Gtk.Enums;
with Gtk.Main;
with Gtk.Window;

procedure Splashdemo is

   Window : Gtk.Window.Gtk_Window;
   Dummy  : Glib.Main.G_Source_Id;

   function Destroy
     return Boolean
   is
      use type Gtk.Window.Gtk_Window;
   begin
      Gtk.Window.Destroy (Window);
      Gtk.Main.Main_Quit;
      return False;
   end Destroy;

begin
   Gtk.Main.Init;
   Gtk.Window.Gtk_New (Window, Gtk.Enums.Window_Popup);
   Gtk.Window.Set_Size_Request (Window, 640, 480);
   Gtk.Window.Set_Position (Window, Gtk.Enums.Win_Pos_Center);
   Gtk.Window.Show_All (Window);
   Dummy:= Glib.Main.Timeout_Add (2000, Destroy'Unrestricted_Access);
   Gtk.Main.Main;
end Splashdemo;

Size of window and duration of display is hardcoded with the integer
literals. The non-standard 'Unrestricted_Access is necessary in this
example because Destroy in this case is a nested function, if you put
the whole thing in an own package, then you can make both at the same
level and use 'Access.

I hope this helps.

Greetings,
Stefan

you hadn't to deduce it :-)
i tried it, hopping it would work, then i saw that it didn't work,  
and then i told you :-)
