sorry, sometimes I don't know what to write to be clear.


i'm trying to implement these interfaces :

http://svn.savannah.gnu.org/viewvc/rapid/branches/gtkada-2.24/src/tki/mcc
_tki/mcc-tki-image.ads?view=markup&pathrev=257
( https://urlpetite.fr/hfd )

http://svn.savannah.gnu.org/viewvc/rapid/branches/gtkada-2.24/src/tki/mcc
_tki/mcc-tki-widget-picture.ads?view=markup&pathrev=257
( https://urlpetite.fr/olk )

http://svn.savannah.gnu.org/viewvc/rapid/branches/gtkada-2.24/src/tki/mcc
_tki/mcc-tki-widget-button-picture.ads?view=markup&pathrev=257
( https://urlpetite.fr/p48 )


it was done with a very old version of gtkada.
i'm with gtkada-2.24. it works, but it uses some components that were 
already Obsolescent in gtkada-2.24, like Gtk.Pixmap.

of ourse the goal is to update it to the latest version of gtkada.
to make it easier, an intermediate step is to update it properly to 
gtkada-2.24, without Obsolescent components.

i edited the corresponding bodies :

http://svn.savannah.gnu.org/viewvc/rapid/branches/gtkada-2.24/src/peers/G
tk/mcc-tki-image.adb?view=markup&pathrev=257
( https://urlpetite.fr/2uf )

http://svn.savannah.gnu.org/viewvc/rapid/branches/gtkada-2.24/src/peers/G
tk/mcc-tki-widget-picture.adb?view=markup&pathrev=257
( https://urlpetite.fr/nso )

http://svn.savannah.gnu.org/viewvc/rapid/branches/gtkada-2.24/src/peers/G
tk/mcc-tki-widget-button-picture.adb?view=markup&pathrev=257
( https://urlpetite.fr/gl3 )


for mcc.tki.Image.External_Image i use Gtk.Image.Gtk_Image.

for mcc.tki.Widget.Button.Picture.Picture_Button i keep 
Gtk.Button.Gtk_Button,
and both Create and Set_Image work fine, thanks to Gtk.Button.Set_Image.

for mcc.tki.Widget.Picture.Picture, if i keep 
Gtk.Event_Box.Gtk_Event_Box and I replace Gtk.Pixmap.Gtk_Pixmap by 
Gtk.Image.Gtk_Image, it seems to be no pb to change the child of the 
Gtk_Event_Box, but nothing is displayed (including for Create) !

(on the other case, if I replace Gtk.Event_Box.Gtk_Event_Box by 
Gtk.Image.Gtk_Image, Create works but Set_Image don't.)



is it clear enough ?
do you need to read my code ?
do you need some test code ?
