Calling Gtk.Image.Gtk_New (Lady, "Ada_9X.bmp"); with a nonexisting file does not report any problem. It just creates a tiny placeholder.
Is there a way to get a warning in this case? The GtkAda_RM is silent on this.

"...If the file isn't found or can't be loaded, the resulting
Gtk.Image.Gtk_Image will display a "broken image" icon. This function
never returns null, it always returns a valid Gtk.Image.Gtk_Image widget..."

Embed Ada_9X.bmp into your GtkAda program. It will always be there, no
need to care about shipping the image file with your program.

Tnanks, Dmitry, I thought about this but do not know how to do this.

I have a small Ada utility program converting an XPM image to Ada
packages. E.g. open BMP in GIMP and export it as XPM.

Dmitry,
I've produced the files Ada_9X_xpm-image.ads/adb .
Problem is: Ada_9X_xpm.adb starts thus:

with Gdk.Pixbuf.Conversions; <-- GNAT complains: file not found
package body Ada_9X_xpm is

Have I overlooked something in your documentation?

It is a helper package from the GtkAda contributions:

----------------------------------
-- GtkAda 2.14.2 introduced a backward incompatibility by making
-- Gdk_Pixbuf a tagged type rather than plain pointer. This package is
-- provided for backward compatibility of the GtkAda Contributions.
--
-- !!WARNING!! Use only with GtkAda >= 2.14.2
--
with Gdk.Pixbuf; use Gdk.Pixbuf;
with GLib.Object; use GLib.Object;
with System; use System;

with Glib.Properties;
with Gtk.Cell_Renderer_Pixbuf;

package Gdk.Pixbuf.Conversions is
--
-- From_Address -- Ada object creation
--
-- Object - Obtained from a GDK call
--
-- Returns :
--
-- The Ada object
--
function From_Address (Object : Address) return Gdk_Pixbuf
renames Convert;
--
-- To_Address -- Getting C object address
--
-- Object - An Ada object
--
-- Returns :
--
-- The C object's address
--
function To_Address
( Object : access GObject_Record'Class
) return Address renames GLib.Object.Get_Object;
--
-- Set_Pixbuf_Property -- Set pixbuf property
--
procedure Set_Pixbuf_Property
( Object : access GObject_Record'Class;
Name : Glib.Properties.Property_Object :=
Gtk.Cell_Renderer_Pixbuf.Pixbuf_Property;
Value : access GObject_Record'Class
) renames Glib.Properties.Set_Property;

subtype To_Value is Gdk_Pixbuf;

end Gdk.Pixbuf.Conversions;

I replaced the call of your Gdk.Pixbuf.Conversions.From_Address in the generated file by
the original Gdk.Pixbuf.Convert.

The embedding works fine. Thanks again.
