What are Signal Marshallers?
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....
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.
So the function named:
gtk_marshal_BOOL__POINTER_INT_INT_UINT(GtkObject*, GtkSignalFunc, gpointer, GtkArg*);
will call the #GtkSignalFunc assuming it was a function with signature:
gboolean sigfunc(gpointer,gint,gint,guint);
Writing Custom Marshals
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.
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:
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);
}
Add an array of signals to a #GtkObjectClass.
Usually this is called when registering a new type of object.
@klass: the object class to append signals to.
@signals: the signals to append.
@nsignals: the number of signals being appended.

This signal is emitted when text is deleted from
the widget by the user. The default handler for
this signal will normally be responsible for inserting
the text, so by connecting to this signal and then
stopping the signal with gtk_signal_emit_stop(), it
is possible to modify the inserted text, or prevent
it from being inserted entirely. The @start_pos

@Returns:
Mark an allocated object as constructed.
This is used for situations
that require precise control of the construction process.
This is done when gtk_object_default_construct() is inadequate.
In #GtkCList the need arises because #GtkCList does construction work that
must happen after its derivers. This work
cannot be done in an initializer function, so an alternate
constructor is mandatory. It calls gtk_object_constructed() to
indicate it has done its job, so that no other constructor will
be invoked.
Normally this function is just automatically run from
gtk_object_default_construct().
@object: object which has been constructed. This is usually
done automatically by gtk_object_new() and gtk_object_newv().
This function is called to construct arguments that haven't been initialized
but have the #GTK_ARG_CONSTRUCT flag set.
All number arguments are set to 0. All pointers and strings
are set to NULL.
Normally invoked by gtk_object_new() automatically; gtk_type_new() can
be used to bypass it.
@object: the object to initialize.
Internal to #GtkLabel.
@buffer:
Query information about an argument type.
@object_type: type of object to query about.
@arg_name: name of the argument.
@info_p: pointer to be filled in with a pointer to the GtkArgInfo.
@Returns: an error message, or NULL on success.
It is the caller's responsibility to call g_free() in the event of error.
@GTK_TREE_SELECTION_SINGLE:
@GTK_TREE_SELECTION_MULTI:
Setting this with a GtkType of GTK_TYPE_SIGNAL connects
the signal to the object, so that the signal is always run

A macro that returns a GList that contains the selection of the root tree of @obj.
@obj: A pointer to the #GtkTree. @obj will accept any pointer, but it the pointer does not point to a #GtkTree, the results are undefined.
Causes the "changed" signal to be emitted.
@editable: a #GtkEditable widget.
Set an array of arguments.
@object: the object whose arguments should be set.

This signal is emitted when text is inserted into
the widget by the user. The default handler for
this signal will normally be responsible for inserting
the text, so by connecting to this signal and then
stopping the signal with gtk_signal_emit_stop(), it
is possible to modify the inserted text, or prevent
it from being inserted entirely.
@editable: the object which received the signal.
@new_text: the new text to insert.
@new_text_length: the length of the new text.
@position: the position at which to insert the new text.
this is an in-out paramter. After the signal
emission is finished, it should point after
the newly inserted text.

at run-time.
@class_type: the GtkType of the ObjectClass
(returned from GTK_OBJECT_CLASS(class)->type for example).
@arg_flags: if non-NULL, obtains the #GtkArgFlags that apply to

@n_args: the number of arguments is returned in this field.
@Returns: an array of arguments, that you must deallocate with g_free().

@foreign_type: Must be a GtkType with a sequence number of zero. Must not be a
fundamental type.
@varargs_type: Must be a GtkType which is either structured or flag, or NONE.
Given a GtkTypeClass pointer @klass, and a GtkType @cast_type, make
sure that it's okay to cast something of that @klass into a @cast_type.
@klass: GtkTypeClass*
@cast_type: GtkType
@Returns: Always return @klass.
Setting this with a GtkType of GTK_TYPE_SIGNAL connects
the signal to the object, so that the user data and objects
and swapped when the signal handler is invoked,
and so that the handler is invoked after all others.
See gtk_signal_connect_object_after() for more details.

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

@row: the row to move to. (A negative value indicates
the last row)
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)
By default, there are no such functions.
@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.

@text:
A set of bit flags used to specify the filter being set
when calling gtk_font_selection_dialog_set_filter() or
gtk_font_selection_set_filter().
@GTK_FONT_FILTER_BASE: the base filter, which can't be changed by the user.
@GTK_FONT_FILTER_USER: the user filter, which can be changed from within the
'Filter' page of the #GtkFontSelection widget.
An action signal. Move the cursor position.
@editable: the object which received the signal.
@x: horizontal distance to move the cursor.
@y: vertical distance to move the cursor.
Return the class of the parent. Initialize the class if necessary.
Return NULL if anything goes wrong.
@type: GtkType
@Returns: gpointer to the klass.
A function which you can use to clean up when the
signal handler is destroyed.
For example, if your handler requires a few variables
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).
@data: The user data associated with the hook that is being
destroyed.

Setting this with a GtkType of GTK_TYPE_SIGNAL connects
the signal to the object, so that the user data and objects
and swapped when the signal handler is invoked.
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.

The pointer is allocated just for you: you must g_free() it.
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.
