Function
GObjectsignal_connect_object
Declaration [src]
gulong
g_signal_connect_object (
GObjectTypeInstance* instance,
const gchar* detailed_signal,
GCallback c_handler,
GObject* gobject,
GConnectFlags connect_flags
)
Description [src]
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 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 for more details.
This function is not directly available to language bindings.
