help on gtk.

["sameer tandra" <sameer tandra gmail com>]

Hi I am Sameer.

                        I am working on GTK. I have a problem when running the program  i.e "Segmentation Fault".

 

I am trying to add two buttons to the container window.First the window is displayed but when i tried to append the buttons to container  it is giving runtime error.

 

The program is as follows:

 

#include <gtk/gtk.h>

static void callback( GtkWidget *widget,
                      gpointer   data )
{
    g_print ("Hello again - %s was pressed\n", (char *) data);
}

int main( int   argc,
          char *argv[] )
{
    GtkWidget *window;
    GtkWidget *button;
    GtkWidget *table;

    gtk_init (&argc, &argv);
   
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title (GTK_WINDOW (window), "Table");
    g_signal_connect (G_OBJECT (window), "delete_event",
                      G_CALLBACK (delete_event), NULL);
    gtk_container_set_border_width (GTK_CONTAINER (window), 20);
    table = gtk_table_new (2, 2, TRUE);
    gtk_container_add (GTK_CONTAINER (window), table);
    button = gtk_button_new_with_label ("button 1")
    g_signal_connect (G_OBJECT (button), "clicked",
               G_CALLBACK (callback), (gpointer) "button 1")
    gtk_table_attach_defaults (GTK_TABLE (table), button, 0, 1, 0, 1);
    gtk_widget_show (button);
    button = gtk_button_new_with_label ("button 2");
    g_signal_connect (G_OBJECT (button), "clicked",
                      G_CALLBACK (callback), (gpointer) "button 2");
    gtk_table_attach_defaults (GTK_TABLE (table), button, 1, 2, 0, 1);
    gtk_widget_show (button);
    gtk_widget_show (table);
    gtk_widget_show (window);
    gtk_main ();
    return 0;
}

please help me.

thanks in advance.
