Hello, I did same questions in channel #Gtk in irc.gnome.org, but they
told me there's not a specific widget to get numeric data, they did
suggest me GtkSpinbutton, but it's not I need, then I use a GtkEntry to
get numeric data, in callback I use 'atoi' function to covert string into
integer.


#include <stdlib.h>

void callback(GtkWidget *entry)
{
    gint num;
    gchar *str;
    stpcpy(str,gtk_entry_get_text(GtkEntry(entry)));
    num = atoi(str);
    printf("Numeric data is: %d", num);
}
