其中有这么一句gdk_window_set_cursor(eventBox->window, gdk_cursor_new(GDK_HAND1));
编译命令是gcc `pkg-config --cflags --libs gtk+-3.0`
编译时提示GtkWidget下没有window成员 可是我在帮助文档下确实找到GtkWidget下有window这个这个属性啊
看了网上很多教程也是这样调用window的啊 怎么回事啊 求教！！！！
下面是源码：

#include <gtk/gtk.h>
static gboolean button_pressed(GtkWidget *, GdkEventButton *, GtkLabel *);
int main(int argc, char *argv[])
{
     GtkWidget *window, *eventBox, *label;
     gtk_init(&argc, &argv);
     window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
     gtk_window_set_title(GTK_WINDOW(window), "Event Box");
     gtk_container_set_border_width(GTK_CONTAINER(window), 10);
     gtk_widget_set_size_request(window, 200, 50);

     eventBox = gtk_event_box_new();
     label = gtk_label_new("Double-Clicked Me!");
     gtk_event_box_set_above_child(GTK_EVENT_BOX(eventBox), FALSE);

     g_signal_connect(G_OBJECT(eventBox), "button_press_event",
                 G_CALLBACK(button_pressed), (gpointer)label);
     gtk_container_add(GTK_CONTAINER(eventBox), label);
     gtk_container_add(GTK_CONTAINER(window), eventBox);
     gtk_widget_set_events(eventBox, GDK_BUTTON_PRESS_MASK);
     gtk_widget_realize(eventBox);

/*下面这一句错误event->window 编译提示GtkWidget 没有window成员
   但是我查看GtkWidget类的成员确实发现有window属性啊*/
     gdk_window_set_cursor(eventBox->window, gdk_cursor_new(GDK_HAND1));
     gtk_widget_show_all(window);

     gtk_main();
     return 0;
}

static gboolean button_pressed(GtkWidget *eventbox, GdkEventButton *event,
             GtkLabel *label)
{
      if(event->type == GDK_2BUTTON_PRESS)
     {
         const gchar *text = gtk_label_get_text(label);
         if(text[0] == 'D')
           gtk_label_set_text(label, "I was double-clicked!");
         else
           gtk_label_set_text(label, "Double clicked me again");
     }
     return FALSE;
}
