[Glade-users] Program debugging in GPS 2013

[bertus.dries at planet.nl (Bertus Dries)]

I just found the problem. By downloading XML Notepad I could just put GPS 
2013 and XML Notepad beside each other and I found the problem. I don't 
think I would have found it by just searching in Glade and/or GPS 2013 
together. It would be a good idea to create in glade a list of all the 
signals in a project and creating an error message within Do_Connect which 
signal is the problem.

JP,

I am using Windows 7 and am programming in Ada. and I am using Glade 3.14.2.

In the Debugger console of GPS 2013 the following Is presented
(gdb) run
Starting program: E:\ada\project\ConvertCtoAda\ConvertCtoAda.exe
[New Thread 7924.0x1600]
[New Thread 7924.0x1460]
[New Thread 7924.0xbd4]
[New Thread 7924.0x1574]
[Inferior 1 (process 7924) exited with code 01]

The code up to the position where the "error" occurred is

   procedure Init is
      Object               : GObject;
   begin
      -------------------------------------------------------------------------
      -- Step 1: create a Builder and add the XML data,
      -------------------------------------------------------------------------
      Gtk_New (Builder);
      nr_Error := Add_From_File (Builder, "ConvertCtoAda.glade",
Error'Access);
      if Error /= null then
         answer := Message_Dialog( Msg     => "Error : " & Get_Message
(Error),
                                   Buttons => Button_OK,
                                   Title   => "Error");
         Error_Free (Error);
         return;
      end if;
      -------------------------------------------------------------------------
      -- Step 2: add calls to "Register_Handler" to associate your
      --         handlers with your callbacks.
      -------------------------------------------------------------------------
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "main_quit", -- from XML file <signal handler=..>
         Handler      => On_Window_Destroy'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_New", -- from XML file <signal handler=..>
         Handler      => On_File_New'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Open", -- from XML file <signal handler=..>
         Handler      => On_File_Open'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Save", -- from XML file <signal handler=..>
         Handler      => On_File_Save'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Save_As", -- from XML file <signal handler=..>
         Handler      => On_File_Save_As'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Print", -- from XML file <signal handler=..>
         Handler      => On_File_Print'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Quit", -- from XML file <signal handler=..>
         Handler      => On_File_Quit'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Cut", -- from XML file <signal handler=..>
         Handler      => On_Edit_Cut'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "Copy_Activate", -- from XML file <signal
handler=..>
         Handler      => On_Edit_Copy'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Paste", -- from XML file <signal handler=..>
         Handler      => On_Edit_Paste'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Delete", -- from XML file <signal handler=..>
         Handler      => On_Edit_Delete'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Show_Inter_Buffer", -- from XML file <signal
handler=..>
         Handler      => On_Show_Inter_Buffer'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_About_Activate", -- from XML file <signal
handler=..>
         Handler      => On_Help_About'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Inter_Buffer_OK", -- from XML file <signal
handler=..>
         Handler      => On_Interbuffer_OK'Access);
      Register_Handler
        (Builder      => Builder,
         Handler_Name => "On_Inter_Buffer_Print", -- from XML file <signal
handler=..>
         Handler      => On_Interbuffer_Print'Access);
      -------------------------------------------------------------------------
      -- Step 3: call Do_Connect. Once to connect all registered handlers
      -------------------------------------------------------------------------
      Do_Connect (Builder); -- The program does not return from this
function.

I checked as good as I could the case sensitive handler names and have all
names copied from the glade program.
Sorry, but I did not mention the programming language because I think it has
little to do with the problem. What I would like is a debugging tool that
could specify where the problem is.

Hi you need to be a little more specific about your environment,
which language are you using?
Its better to refer to the language binding documentation to know
exactly how your functions/method map in builder handler names

BTW, is there any output in the console when you run your program?

cheers

JP
