Function
GObjectsignal_connect_data
Declaration [src]
gulong
g_signal_connect_data (
  GObject* instance,
  const gchar* detailed_signal,
  GCallback c_handler,
  gpointer data,
  GClosureNotify destroy_data,
  GConnectFlags connect_flags
)
Description [src]
Connects a GCallback function to a signal for a particular object. Similar
to g_signal_connect(), but allows to provide a GClosureNotify for the data
which will be called when the signal handler is disconnected and no longer
used. Specify connect_flags if you need ..._after() or
..._swapped() variants of this function.
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.
