<para>
All the functions in here are marked a Non-public.
We describe it anyway because it is occasionally useful
to understand how the work is done.
</para>
<para>
Arguments are a way of describing a named parameter to a function.
They have two important roles within gtk+:
<itemizedlist>
<listitem>
<para>
they describe <wordasword>object properties</wordasword>.
This means that they present an interface to get and set a named-type
for any type of object in a consistent way.
(All the relevant functions to do this start with gtk_object_set
or gtk_object_get).
</para>
</listitem>
<listitem>
<para>
they describe <wordasword>signal arguments</wordasword>.
This is a lot less often needed but still useful.
Usually if you are just emitting or creating a particular signal
it is more convenient to just use gtk_signal_emit() or gtk_signal_new().
However if you are writing a function to emit or create an arbitrary
signal, you must use gtk_signal_emitv() or gtk_signal_newv().

<!-- ##### SECTION ./tmpl/gtkdata.sgml:Long_Description ##### -->
<para>
The #GtkData object is a very simple object intended to be used as a base
class for objects which contain data (i.e. the 'Model' in the object-oriented
Model/View/Controller framework).
</para>
<para>
Currently it is not very useful since all it provides is a "disconnect" signal.
This signal could be emitted by a #GtkData subclass to notify any 'Views'
that they should disconnect from the #GtkData (the 'Model'), possibly just
before the #GtkData is destroyed.

<title>What are Signal Marshallers?</title>
<para>
Marshals are functions which all have the same prototype:
they take a #GtkObject, a #GtkSignalFunc, a #gpointer,
and an array of argument values.
The functions are names gtk_marshall_RETURNTYPE__PARAMTYPE1_PARAMTYPE2....
</para>
<para>
They then call a native function:  the GtkObject is the first
parameter passed in.  The arguments are passed in the native
calling convention:  chars, shorts, ints, longs may be packed
on the stack, or tucked in registers:  it doesn't matter
because the same calling convention will be generated
inside the gtkmarshal code as is expected where you define
your handlers.
</para>
<para>
So the function named:
<programlisting>
gtk_marshal_BOOL__POINTER_INT_INT_UINT(GtkObject*, GtkSignalFunc, gpointer, GtkArg*);
</programlisting>
will call the #GtkSignalFunc assuming it was a function with signature:
<programlisting>
gboolean sigfunc(gpointer,gint,gint,guint);
</programlisting>
</para>
</refsect2>
<refsect2>
<title>Writing Custom Marshals</title>
<para>
Marshals are primarily used as arguments to gtk_signal_new().
Sometimes, you may find that a marshaller you need isn't available
in the standard list.  Then you have to write your own.
</para>
<para>
If you wish to define a signal with a new type of argument list.
Suppose you want 2 pointers and 2 integers.
You would write:
<programlisting>
typedef int (*GtkSignal_INT__POINTER_POINTER_INT_INT)(
                        gpointer, gpointer, gint, gint
);

void marshal_INT__POINTER_POINTER_INT_INT(GtkObject*    object,
                                           GtkSignalFunc func,
                                           gpointer      func_data,
                                           GtkArg*       args)
{
        GtkSignal_NONE__POINTER_POINTER_INT_INT rfunc;
        gint* return_val;
        return_val = GTK_RETLOC_INT(args[4]);
        rfunc = (GtkSignal_INT__POINTER_POINTER_INT_INT)func;
        *return_val = (*rfunc)(object,
                               GTK_VALUE_POINTER(args[0]),
                               GTK_VALUE_POINTER(args[1]),
                               GTK_VALUE_INT(args[2]),
                               GTK_VALUE_INT(args[3]),
                               func_data);
}

<!-- ##### SIGNAL GtkEditable::insert-text ##### -->
<para>
This signal is emitted when text is inserted into

This is useful for handlers that are primarily notifying
other objects and could just invoke an already existing function
if the parameters were swapped.
See gtk_signal_connect_object() for more details.
</para>


<!-- ##### ARG GtkObject:object-signal-after ##### -->
<para>
Setting this with a GtkType of GTK_TYPE_SIGNAL connects
the signal to the object, so that the user data and objects

<para>
A function which you can use to clean up when the
signal handler is destroyed.
</para>
<para>

that you made into a struct and allocated (using g_new()
or something), then you will probably want to free
it as soon as the hook is destroyed.  This will
allow you to do that. (For this in particular
it is convenient to pass g_free() as a #GtkSignalDestroy
function).
</para>

destroyed.

constructor is mandatory.  It calls gtk_object_constructed() to
indicate it has done its job, so that no other constructor will
be invoked.

Returns whether a connection id is valid (and optionally not blocked).
</para>

@object: the object to search for the desired handler.
@handler_id: the connection id.
@may_be_blocked: whether it is acceptable to return a blocked
handler.

unless #may_be_blocked was specified.  FALSE otherwise.

<!-- ##### FUNCTION gtk_signal_handlers_destroy ##### -->
<para>

<!-- ##### FUNCTION gtk_signal_init ##### -->
<para>

</para>


<!-- ##### FUNCTION gtk_signal_n_emissions ##### -->
<para>
Find out the recursion depth of emissions for a particular type
of signal and object.  (So it will
always return 0 or 1 if #GTK_RUN_NO_RECURSE is specified)
This is a way to avoid recursion:  you can see if
you are currently running in that signal handler and emit it only
if you are.
</para>
<para>Another way to look at it is that this number increases
by one when #gtk_signal_emit(), et al, are called,
and decreases by one when #gtk_signal_emit() returns.
</para>

@object: the object with the signal handler.
@signal_id: the signal id.
@Returns: the recursion depth of emissions of this signal for this
object.

<!-- ##### FUNCTION gtk_signal_n_emissions_by_name ##### -->
<para>
Find out the recursion depth of emissions for a particular type
of signal and object.  Just like gtk_signal_n_emissions()
except it will lookup the signal id for you.
</para>

@object: the object with the signal handler.
@name: the signal name.
@Returns: the recursion depth of emissions of this signal for this
object.

<!-- ##### FUNCTION gtk_signal_query ##### -->
<para>
Obtain information about a signal.
</para>

@signal_id: the signal type identifier.
@Returns: a pointer to a GtkSignalQuery structure
which contains all the information, or NULL.
The pointer is allocated just for you:  you must g_free() it.

<!-- ##### FUNCTION gtk_signal_remove_emission_hook ##### -->
<para>
Delete an emission hook. (see gtk_signal_add_emission_hook())
</para>

@signal_id: the id of the signal type.

@i: 
@h: 

<!-- ##### FUNCTION gtk_signal_set_funcs ##### -->
<para>
These set default functions to call when the user didn't
supply a function when connecting.  (These are rarely
used, and probably only for language bindings)
</para>
<para>
By default, there are no such functions.
</para>

@marshal_func: the function to invoke on every handlers for which there
isn't a function pointer.  May be NULL.
@destroy_func: the function to invoke when each hook is destroyed.
May be NULL.

@shadow_type: the new border type.

@dummy: unused.
@line: line number (used within macros).
@do_ref: whether to reference or unreference.
