g_signal_connect_swapped() 和g_signal_connect() 相同,只是回调函数只用一个参数,一个指向 GTK 对象的指针。所以当使用这个函数连接信号时,回调函数应该是这样的形式 void callback_func( GtkObject *object ); 这个对象通常是一个构件。然而我们一般不用函数g_signal_connect_swapped() 设置回调。它们常用来调...
g_signal_connect_swapped(instance, detailed_signal, c_handler, data); connects a GCallback function to a signal for a particular object. The instance on which the signal is emitted and data will be swapped when calling the handler. 我不太明白这是什么意思。这是否意味着data将指向instance指向的...
