Re: [gtk-osx-users] Pasting images from clipboard

[Miroslav Rajcic <mrajcic hotmail com>]

I can confirm that this patch works OK. I actually modified sample to use this function (instead of patching 
GTK+ itself):

GdkPixbuf *gtk_clipboard_wait_for_image1 (GtkClipboard *clipboard)
{
        GdkAtom target = gdk_atom_intern_static_string("image/tiff");
        GtkSelectionData *data = gtk_clipboard_wait_for_contents (clipboard, target);
        if (data && data->data){
                GdkPixbuf *pixbuf = gtk_selection_data_get_pixbuf (data);
                gtk_selection_data_free (data);
                return pixbuf;
        }
        return NULL;
}

And it reported success.
I suppose this is a temporary code, because it only looks for tiff format?

Regards,
  Miroslav

I haven't yet made a patch for gtk-osx, I expected you to go test with a git clone. The change is below: 
Apply it and try again.
