problems for C++( use gtk1.2.6)

["Chiou Wei-Han" <s7410010 ntut edu tw>]

Hi. I have some problem with my codes.

Because I want to use C++ in GTK+, not gtk--. But I have a little trouble. 

I write one class and have three files. They're bellow:

/* myFrame.cc */
#include <gtk/gtk.h>
#include "main_window.h"

void main( gint argc , char * argv[] )

{
     gtk_init( &argc , &argv );

     main_window window;

     window.create_main_frame();
     gtk_main();    

}

/* main_window.h */

#ifndef MAIN_WINDOW_H
#define MAIN_WINDOW_H

#include <gtk/gtk.h>
#include <math.h>

class main_window
{
public:
      main_window() {}
      ~main_window() {}

      void test1();
      void test2();

      //callback function;
      void do_exit( GtkWidget * widget , GtkWidget * window );
      void create_main_frame();

};

#endif

/*main_window.cc */

#ifndef MAIN_WINDOW_CC
#define MAIN_WINDOW_CC

#include "main_window.h"

void main_window::test1() {}
void main_window::test2() {}

void main_window::do_exit( GtkWidget * widget , GtkWidget * window )
{
     gtk_widget_destroy( window );
     gtk_main_quit();
}

void main_window::create_main_frame()
{
     void (main_window::*exit)( GtkWidget * widget , GtkWidget * window ) = &main_window::do_exit;

     struct
     {
        char * label;
        void (main_window::*func)();
     }
     buttons[] = {
       {"TEST Button1" , &main_window::test1} ,
       {"TEST Button2" , &main_window::test2 } , 

     };
     int no_buttons = sizeof(buttons)/ sizeof (buttons[0]);

     GtkWidget * window;
     GtkWidget * close_button;
     GtkWidget * button;
     GtkWidget * up_box;
     GtkWidget * down_box;

     window = gtk_window_new( GTK_WINDOW_TOPLEVEL );

     //set window's size;
     gtk_widget_set_usize( window , 200 , 250 );
     gtk_widget_set_uposition( window , 10 , 10 );

     //signal process;
     gtk_signal_connect( GTK_OBJECT(window) , "destroy" , GTK_SIGNAL_FUNC(gtk_main_quit) , NULL );
     //create a new vertical box;
     up_box = gtk_vbox_new( FALSE , 0 );
     gtk_container_add( GTK_CONTAINER(window) , up_box );    
     gtk_container_border_width( GTK_CONTAINER(up_box) , 10 );

     for( int i=0 ; i < no_buttons ; i++ )
     {
          //create a new button;
          button = gtk_toggle_button_new_with_label(buttons[i].label);

          gtk_signal_connect( GTK_OBJECT(button) , "clicked" , GTK_SIGNAL_FUNC(&buttons[i].func) , NULL );
          gtk_box_pack_start( GTK_BOX(up_box) , button , TRUE , TRUE , 0 );
      }

     //create a new vertical box;
     down_box = gtk_vbox_new( FALSE , 10 );
     gtk_container_border_width( GTK_CONTAINER(down_box) , 10 );
     gtk_box_pack_start( GTK_BOX(up_box) ,down_box , FALSE , TRUE , 0 );

 

     GtkWidget * separator = gtk_hseparator_new();
     gtk_box_pack_start( GTK_BOX(down_box) , separator , FALSE , TRUE , 3 );
 
     //create a new button about close window;
     close_button = gtk_button_new_with_label( "Close" );
     gtk_signal_connect( GTK_OBJECT(close_button) , "clicked" , GTK_SIGNAL_FUNC(&exit) , window );
     gtk_box_pack_start( GTK_BOX(down_box) , close_button , TRUE , TRUE , 0 );
     GTK_WIDGET_SET_FLAGS( close_button , GTK_CAN_DEFAULT );
     gtk_widget_grab_default( close_button );

     gtk_widget_show_all( window );

}

#endif

And my makefile is like this.

/*makefile*/

myFrame: myFrame.cc main_window.o
g++ -O3 `gtk-config --cflags` myFrame.cc main_window.o -o myFrame `gtk-config --libs`

 

main_window.o: main_window.cc main_window.h
 g++ -O3 -c main_window.cc
//...........................

my codes can be compile(didn't have any error). But, if executing the  program, it'll crash and close. And tell me this:

    Illegal instruction ( core dumped)

Please help me. Thanks a lot.
