[gtkada] Where are the buttons in Dialog and Filechooser Dialog

[bertus.dries at planet.nl]

I Now have placed yhe following lines in after

File_Dialog := Gtk_File_Chooser_Dialog_New

in the program:

FC_Cancel := Add_Button(Gtk_Dialog(File_Dialog), "Cancel", 
Gtk_Response_Cancel);
FC_OK := Add_Button(Gtk_Dialog(File_Dialog), "OK", Gtk_Response_OK);

I needed the enter the conversion of File_Dialog to Gtk_Dialog format.
Now I get two Buttons but they still do not rtespond

You always needed to add the buttons explicitly, via a call to 
Gtk.Dialog.Add_Button.
One of the changes they did in recent versions of gtk+ though is that 
depending on the
theme, the buttons are displayed in the title bar rather than at the bottom 
of the
dialog.
See the GtkAda specific subprogram Gtk.Dialog.Use_Header_Bar_From_Settings
