问个GTK＋的简单问题。往container里添加并设置widget属性时，为什么没有用？

mywayliu

刚开始学习GTK，看着文档想试试几个函数，结果不成功，不晓得为什么，用anjuta写的（那些时间的回调函数没贴上来）。代码如下：
为什么红色的那行执行起来没用阿？就是往container中加入widget同时设置属性，但是运行起来没有任何效果。。。

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

    gtk_init (&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
   
   
    g_signal_connect(G_OBJECT(window), "delete_event", G_CALLBACK (delete_event), NULL);
   
    g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(destroy), NULL);

    button = gtk_button_new ();


    g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK (hello), NULL);
//   gtk_button_set_label(GTK_BUTTON(button) , "hello");
   
    g_signal_connect_swapped (G_OBJECT (button), "clicked", G_CALLBACK (gtk_widget_destroy), window);
   
    gtk_container_add (GTK_CONTAINER (window), button);
    gtk_container_child_set(GTK_CONTAINER(window), button, "label", "hello", NULL);

    gtk_widget_show (button);
    gtk_widget_show (window);
   
    gtk_main ();
    return 0;
}

第一次发帖就没人回复。。。。郁闷到了。不过我自己解决了。。。。

看了下doc，解释是：
GtkContainer introduces childproperties - these are object properties that are not specificto either the container or the contained widget, but rather to their relation.Typical examples of child properties are the position or pack-type of a widgetwhich is contained in a GtkBox.

应该是这个问题。
看来doc才是王道。。。。
