Function
GObjectsignal_connect_object
Declaration
gulong
g_signal_connect_object (
GObjectTypeInstance* instance,
const gchar* detailed_signal,
GCallback c_handler,
GObject* gobject,
GConnectFlags connect_flags
)
Description
This is similar to g_signal_connect_data(), but uses a closure which
ensures that the gobject stays alive during the call to c_handler
by temporarily adding a reference count to gobject.
When the gobject is destroyed the signal handler will be automatically
disconnected. Note that this is not currently threadsafe (ie:
emitting a signal while gobject is being destroyed in another thread
is not safe).
This function is not directly available to language bindings.
