<para>
The GTK+ signal system merely proxies the GLib signal system now. For future

<title>What are signals?</title>
<para>
Signals are a way to get notification when something happens
and to customize object behavior according to the
user's needs.
Every <wordasword>signal</wordasword> is uniquely identified by a name,
"class_name::signal_name", where signal_name might be something like
"clicked" and class_name might be "GtkButton". Note that some other class
may also define a "clicked" callback, so long as it doesn't derive from
#GtkButton.
</para>
<para>
When they are created, they are also assigned a unique positive integer,
the signal id (1 is the first signal id- 0 is used to flag an error).
Each is also tied to an array of types that describes
the prototype of the function pointer(s) (handlers) you may
connect to the signal. Finally, every signal has
a default handler that is given by a function pointer
in its class structure: it is run by default whenever the
signal is emitted. (It is possible that a signal will
be emitted and a user-defined handler will prevent the default handler
from being run.)
</para>
<para>
Signals are used by everyone, but they are only
created on a per class basis -- so you should not call
call gtk_signal_new() unless you are writing
a new #GtkObject type. However, if you want to make a new signal
for an existing type, you may use gtk_object_class_user_signal_new()
to create a signal that doesn't correspond to a class's builtin
methods.
</para>
</refsect2>
<refsect2>
<title>How are signals used?</title>
<para>
There are two basic actions in the signal handling game.
If you want notification of an event, you must <emphasis>connect</emphasis>
a function pointer and a data pointer to that signal; the data pointer
will be passed as the last argument to the function (so long as you
are using the default marshalling functions).
You will receive a connection id, a unique positive integer
corresponding to that attachment.
</para>
<para>
Functions that want to notify the user of certain actions,

<refsect2><title>A brief note on how they work.</title>
<para>
The functions responsible for translating an array of #GtkArgs
to your C compiler's normal semantics are called Marshallers.
They are identified by
gtk_marshal_<replaceable>return_value</replaceable>__<replaceable>parameter_list</replaceable>()
for example a C function returning a gboolean and taking a gint
can be invoked by using gtk_marshal_BOOL__INT().
Not all possibly combinations of return/params are available,
of course, so if you are writing a #GtkObject with parameters
you might have to write a marshaller.

This function aborts a signal's current emission.
</para>
<para>
It will prevent the default method from running,
if the signal was #GTK_RUN_LAST and you connected
normally (i.e. without the "after" flag).
</para>
<para>
It will print a warning if used on a signal which
isn't being emitted.

<!-- ##### MACRO gtk_signal_connect_object ##### -->
<para>
This function is for registering a callback that will
call another object's callback. That is,
instead of passing the object which is responsible
for the event as the first parameter of the callback,
it is switched with the user data (so the object which emits
the signal will be the last parameter, which is where the
user data usually is).
</para>
<para>
This is useful for passing a standard function in as a callback.
For example, if you wanted a button's press to gtk_widget_show()
some widget, you could write:
</para>
<informalexample>
<programlisting>
gtk_signal_connect_object (button, "clicked", gtk_widget_show, window);
</programlisting>
</informalexample>
@object: the object which emits the signal.
@name: the name of the signal.
@func: the function to callback.
@slot_object: the object to pass as the first parameter to func.
(Though it pretends to take an object, you can
really pass any gpointer as the #slot_object .)
@Returns: the connection id.
@Deprecated: Use g_signal_connect_swapped() instead.
<!-- ##### MACRO gtk_signal_connect_object_after ##### -->
<para>
Attaches a signal hook to a signal, passing in an alternate
object as the first parameter, and guaranteeing
that the default handler and all normal
handlers are called first.
</para>
@object: the object associated with the signal.
@name: name of the signal.
@func: function pointer to attach to the signal.
@slot_object: the object to pass as the first parameter to #func.
@Returns: the connection id.
@Deprecated: Use g_signal_connect_data() instead, passing
<literal>G_CONNECT_AFTER|G_CONNECT_SWAPPED</literal> as @connect_flags.
<!-- ##### FUNCTION gtk_signal_connect_full ##### -->
<para>
Attaches a function pointer and user data to a signal with
more control.
</para>
@object: the object which emits the signal. For example, a button
in the button press signal.
@name: the name of the signal.
@func: function pointer to attach to the signal.
@unsupported:
@data: the user data associated with the function.
@destroy_func: function to call when this particular hook is
disconnected.
@object_signal: whether this is an object signal-- basically an "object
signal" is one that wants its user_data and object fields switched,
which is useful for calling functions which operate on another
object primarily.
@after: whether to invoke the user-defined handler after the signal, or to let
the signal's default behavior preside (i.e. depending on #GTK_RUN_FIRST
and #GTK_RUN_LAST).
@Returns: the connection id.
@Deprecated: Use g_signal_connect_data() instead.
<!-- ##### FUNCTION gtk_signal_connect_while_alive ##### -->
<para>
Attaches a function pointer and another #GtkObject to a signal.
</para>
<para>
This function takes an object whose "destroy" signal
should be trapped.
That way, you don't have to clean up the
signal handler when you destroy the object.
It is a little less efficient though.
</para>
<para>
(Instead you may call gtk_signal_disconnect_by_data(), if you want
to explicitly delete all attachments to this object. This
is perhaps not recommended since it could be confused
with an integer masquerading as a pointer (through GINT_TO_POINTER()).)
</para>
@object: the object that emits the signal.
@name: name of the signal.
@func: function pointer to attach to the signal.
@func_data: pointer to pass to func.
@alive_object: object whose death should cause the handler connection
to be destroyed.
@Deprecated: Use g_signal_connect_object() instead.
<!-- ##### FUNCTION gtk_signal_connect_object_while_alive ##### -->
<para>
These signal connectors are for signals which refer to objects,
so they must not be called after the object is deleted.
</para>
<para>
Unlike gtk_signal_connect_while_alive(),
this swaps the object and user data, making it suitable for
use with functions which primarily operate on the user data.
</para>
<para>
This function acts just like gtk_signal_connect_object() except
it traps the "destroy" signal to prevent you from having to
clean up the handler.
</para>
@object: the object associated with the signal.
@name: name of the signal.
@func: function pointer to attach to the signal.
@alive_object: the user data, which must be an object, whose destruction
should signal the removal of this signal.
@Deprecated: Use g_signal_connect_object() instead, passing
<literal>G_CONNECT_SWAPPED</literal> as @connect_flags.
<!-- ##### MACRO gtk_signal_disconnect ##### -->
<para>
Destroys a user-defined handler connection.
</para>
@object: the object which the handler pertains to.
@handler_id: the connection id.
@Deprecated: Use g_signal_handler_disconnect() instead.
<!-- ##### MACRO gtk_signal_disconnect_by_func ##### -->
<para>
Destroys all connections for a particular object, with
the given function-pointer and user-data.
</para>
@object: the object which emits the signal.
@func: the function pointer to search for.
@data: the user data to search for.
@Deprecated: Use g_signal_handlers_disconnect_by_func() instead.
<!-- ##### MACRO gtk_signal_disconnect_by_data ##### -->
<para>
Destroys all connections for a particular object, with
the given user-data.
</para>
@object: the object which emits the signal.
@data: the user data to search for.
@Deprecated: Use g_signal_handlers_disconnect_matched() instead.
<!-- ##### MACRO gtk_signal_handler_block ##### -->
<para>
Prevents a user-defined handler from being invoked. All other
signal processing will go on as normal, but this particular
handler will ignore it.
</para>
@object: the object which emits the signal to block.
@handler_id: the connection id.
@Deprecated: Use g_signal_handler_block() instead.
<!-- ##### MACRO gtk_signal_handler_block_by_func ##### -->
<para>
Prevents a user-defined handler from being invoked, by reference to
the user-defined handler's function pointer and user data. (It may result in
multiple hooks being blocked, if you've called connect multiple times.)
</para>
@object: the object which emits the signal to block.
@func: the function pointer of the handler to block.
@data: the user data of the handler to block.
@Deprecated: Use g_signal_handlers_block_by_func() instead.
<!-- ##### MACRO gtk_signal_handler_block_by_data ##### -->
<para>
Prevents all user-defined handlers with a certain user data from being invoked.
</para>
@object: the object which emits the signal we want to block.
@data: the user data of the handlers to block.
@Deprecated: Use g_signal_handlers_block_matched() instead.
<!-- ##### MACRO gtk_signal_handler_unblock ##### -->
<para>
Undoes a block, by connection id. Note that undoing a block doesn't
necessarily make the hook callable, because if you block a
hook twice, you must unblock it twice.
</para>
@object: the object which emits the signal we want to unblock.
@handler_id: the emission handler identifier, as returned by
gtk_signal_connect(), etc.
@Deprecated: Use g_signal_handler_unblock() instead.
<!-- ##### MACRO gtk_signal_handler_unblock_by_func ##### -->
<para>
Undoes a block, by function pointer and data.
Note that undoing a block doesn't
necessarily make the hook callable, because if you block a
hook twice, you must unblock it twice.
</para>
@object: the object which emits the signal we want to unblock.
@func: the function pointer to search for.
@data: the user data to search for.
@Deprecated: Use g_signal_handlers_unblock_by_func() instead.
<!-- ##### MACRO gtk_signal_handler_unblock_by_data ##### -->
<para>
Undoes block(s), to all signals for a particular object
with a particular user-data pointer
</para>
@object: the object which emits the signal we want to unblock.
@data: the user data to search for.
@Deprecated: Use g_signal_handlers_unblock_matched() instead.
<!-- ##### MACRO gtk_signal_handler_pending ##### -->
<para>
Returns a connection id corresponding to a given signal id and object.
</para>
<para>
One example of when you might use this is when the arguments
to the signal are difficult to compute. A class implementor
may opt to not emit the signal if no one is attached anyway,
thus saving the cost of building the arguments.
</para>
@object: the object to search for the desired user-defined handler.
@signal_id: the number of the signal to search for.
@may_be_blocked: whether it is acceptable to return a blocked
handler.
@Returns: the connection id, if a connection was found. 0 otherwise.
@Deprecated: Use g_signal_has_handler_pending() instead.
<!-- ##### MACRO gtk_signal_handler_pending_by_func ##### -->
<para>
Returns a connection id corresponding to a given signal id, object, function
pointer and user data.
</para>
@object: the object to search for the desired handler.
@signal_id: the number of the signal to search for.
@may_be_blocked: whether it is acceptable to return a blocked
handler.
@func: the function pointer to search for.
@data: the user data to search for.
@Returns: the connection id, if a handler was found. 0 otherwise.
<!-- ##### MACRO gtk_signal_default_marshaller ##### -->
<para>
A marshaller that returns void and takes no extra parameters.
</para>
