connect_object

This is similar to 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 cannot fail. If the given signal name doesn’t exist, a critical warning is emitted. No validation is performed on the "detail" string when specified in detailed_signal, other than a non-empty check.

Refer to the [signals documentation](signals.html) for more details.

Parameters:

instance	the instance to connect to.
detailed_signal	a string of the form "signal-name::detail".
gobject	the object to pass as data to c_handler.
c_handler	the ObjectConstructorFunc to connect.
connect_flags	a combination of ConnectFlags.

Returns:

the handler id.
