Don't know why this does not work.

Hi All,
	the following is my first attempt to write a hello world program using
gtk.

#include <gtk/gtk.h>

gint delete_event(GtkWidget *widget, GdkEvent *event, gpointer data)
{
        g_print("This Event is to be deleted\n");
        return (TRUE);
}

void destroy(GtkWidget *widget, gpointer data)
{
        if (data != NULL)
                g_print("%s\n", (char *) data);
        gtk_main_quit();
}

void hello(GtkWidget *widget, GdkEvent *event, gpointer data)
{
        if (data != NULL)
                g_print("%s was pressed.\n", (char *) data);
        else
                g_print ("Hellow World!\n");
}

void crap(GtkWidget *widget, GdkEvent *event, gpointer data)
{
        if (data != NULL)
        {
                g_print("%s was pressed", (char *) data);
        }
        else
                g_print ("Crap!!!\n");
}

int main(int argc, char *argv[])
{
        gtk_init(&argc, &argv);
        guint gi;
        GtkWidget *window, *box1;
        GtkWidget * button1, * button2, *button3;
        window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

        gtk_container_set_border_width(GTK_CONTAINER(window), 40);
        gtk_window_set_title(GTK_WINDOW(window), "My Test Program");

        button1 = gtk_button_new_with_label("Hello Button");
        button2 = gtk_button_new_with_label("Crap Button");
        button3 = gtk_button_new_with_label("Quit");

        box1 = gtk_hbox_new(FALSE, 0);
        gtk_container_add(GTK_CONTAINER(window), box1);

        gtk_signal_connect(GTK_OBJECT(window), "delete_event",
                        GTK_SIGNAL_FUNC(delete_event), NULL);

        gtk_signal_connect(GTK_OBJECT(button1), "clicked",
                        GTK_SIGNAL_FUNC(hello), (gpointer) "Hello
Button");

        gtk_signal_connect(GTK_OBJECT(button2), "clicked",
                        GTK_SIGNAL_FUNC(crap), (gpointer) "Crap
Button");

        gtk_signal_connect(GTK_OBJECT(button3), "clicked",
                        GTK_SIGNAL_FUNC(destroy), (gpointer)
"Quitting");

        gtk_box_pack_start(GTK_BOX(box1), button1, TRUE, TRUE, 0);
        gtk_widget_show(button1);

        gtk_box_pack_start(GTK_BOX(box1), button2, TRUE, TRUE, 0);
        gtk_widget_show(button2);

        gtk_box_pack_start(GTK_BOX(box1), button3, TRUE, TRUE, 0);
        gtk_widget_show(button3);

        gtk_widget_show(box1);
        gtk_widget_show(window);

        gtk_main();

        return (0);
}



-------------------------------------------------

I've compiled it and ran the program.
it seemed to work, however, when I click on "crap" or "hello" button.

I get something like these printed out in my terminal:
¸ct@\ was pressed     <--- it should print "crap button was pressed"

pct was pressed.	<-- it should print "hello button was pressed"


so I"m just curious how g_print should be done properly.

Ps I used "g++ -g -lgtk -lgdk -lglib -o test test.cpp"

command to compile the program.

thanks for the help.


cheers.
