hi :-)

i want to make an Image Button without text and without large borders.

when i use Gtk.Button.Set_Image, it makes spaces at 3 sides, and the
Image overflows at the 4th.
it depends on Gtk.Button.Get_Image_Position : it overflows at the side
where it would have been the text.

Gtk.Box.Get_Spacing (Get_Child (Get_Child (My_Button))) returns 2,
but Gtk.Box.Set_Spacing (Get_Child (Get_Child (My_Button))))), 0) does
not resolve the pb.

Gtk.Container.Get_Border_Width on any level of child of My_Button
returns 0.

i don't find how to remove these spaces.

do you think i should use Gtk.Container.Add instead of
Gtk.Button.Set_Image ?

previous authors have done that, but I feel like it's kind of a hack,
and I don't like it very much...

i gone back to Gtk.Container.Add.

it doesn't more overflow at the 4th side, and that's a good thing,
but i don't understand what's wrong with Gtk.Button.Set_Image.

i was wrong telling "too much spaces with Gtk.Button.Set_Image",
because it's not Set_Image which causes the spaces,
but it's the use of a Gtk_Image instead of a Gtk_Pixmap.

i don't understand more what's the difference between Gtk_Image and
Gtk_Pixmap.

Gtk.Misc.Get_Padding returns 0 0.
i have no other idea now.

it's better with Add than with Set_Image,
but it's not very nice because RAPID has not exactly the same behavior
with Gtk and with TclTk.
(2*4 pixels in a small button (27 pixels) is a big part.)

i cannot revert to Gtk_Pixmap because it is Obsolescent.

so i still need help, please :-)
