Hi,
I have the following sequence in my program:
obj:= last_builder.Get_Object(winname);
if obj=null then raise findobject_Ex with
builder_file & ": " & winname & " not found";
end if;
win.win := Gtk.Window.Gtk_Window (obj);
win.win.Show_All;
When it is executed for the first time, it runs as expected. At the
second time, the window win.win does not open and the following warning
is printed out:
(sos:2905): Gtk-CRITICAL **: gtk_widget_show_all: assertion
'GTK_IS_WIDGET (widget)' failed
For debugging I would like to execute the GTK macro G_OBJECT_TYPE_NAME
but did not find anything similar in gtkada.
So how would you debug this?
