连接和切断信号处理函式
gulong g_signal_connect( GObject *object, const gchar *name, GCallback func, gpointer func_data ); gulong g_signal_connect_after( GObject *object, const gchar *name, GCallback func, gpointer func_data ); gulong g_signal_connect_swapped( GObject *object, const gchar *name, GCallback func, GObject *slot_object ); void g_signal_handler_disconnect( GObject *object, gulong handler_id ); void g_signal_handlers_disconnect_by_func( GObject *object, GCallback func, gpointer data ); |
Blocking and Unblocking Signal Handlers
void g_signal_handler_block( GObject *object, gulong handler_id); void g_signal_handlers_block_by_func( GObject *object, GCallback func, gpointer data ); void g_signal_handler_unblock( GObject *object, gulong handler_id ); void g_signal_handler_unblock_by_func( GObject *object, GCallback func, gpointer data ); |
发出和停止信号
void g_signal_emit( GObject *object, guint signal_id, ... ); void g_signal_emit_by_name( GObject *object, const gchar *name, ... ); void g_signal_emitv( const GValue *instance_and_params, guint signal_id, GQuark detail, GValue *return_value ); void g_signal_stop_emission( GObject *object, guint signal_id, GQuark detail ); void g_signal_stop_emission_by_name( GObject *object, const gchar *detailed_signal ); |
