GTK初学者疑问求教

jacobzz

按着Peter Wright的GTK+/GNOME程序设计这本书上输入程序，
第四章的windowposition这个例程，编译没问题，但是生成的程序不能
正常运行，产生了大量的Gtk-WARNING和Gtk-CRITICAL。但是按着
书输入的前两章的程序编译运行都没有问题，笨人是初学者，刚入门，一
时不知从何着手，还请前辈高人指点一二。
      笨人的系统是FreeBSD 7.2R。
      源程序如下：
#include <gtk12/gtk/gtk.h>

void CloseTheApp(GtkWidget *Window,gpointer data)
{
    gtk_main_quit();
}

void BuildAWindow(const gchar *title,GtkWindowPosition position)
{
    GtkWidget *window;
    window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_position(GTK_WINDOW(window),position);
    gtk_window_set_default_size(GTK_WINDOW(window),320,200);
    gtk_window_set_title(GTK_WINDOW(window),title);
     gtk_signal_connect(GTK_OBJECT(window),"destroy",GTK_SIGNAL_FUNC(CloseTheApp),NULL);
     gtk_widget_show(window);
}

gint main(gint argc,gchar *argv[])
{
    BuildAWindow("Normal",GTK_WIN_POS_NONE);
    BuildAWindow("Center",GTK_WIN_POS_CENTER);
    BuildAWindow("Mouse",GTK_WIN_POS_MOUSE);
     gtk_main();
    return 0;
}

产生的错误如下：

自己真是笨人啊
漏打了一行关键的
gtk_init(&argc,&argv)…………
真是笨啊，绿下自己

treat123

汗！！！楼主这是干嘛！！！
