g_object_notify的使用方法

g_object_notify的使用方法

0、注册部分

     g_object_class_install_property(gobject_class,

                                                        PROP_MODAL,

               g_param_spec_boolean("modal", P_("Modal"), P_("if true, the window is modal( other windows are not usable while this one is up)"),   FALSE, GTK_PARAM_READWRITE)

                                                       );

1、emit部分

     g_object_notify(G_OBJECT(window), "modal");

// 0,1 两步骤属于属性的注册和信号发射，放在同一个类里。

 

2.  connect部分

     g_signal_connect(window, "notify::modal", G_CALLBACK(notify_modal_received), NULL);

3、回调函数

     void notify_modal_received(GtkWidget *window, GParamSpec *pspec)

     {

         printf("notify modal received");

      }

// 2,3 属于信号获取，可以放在需要的类里
