<doc xml:space="preserve">A convenience macro to ease adding private data to instances of a new type
|
|
in the @_C_ section of G_DEFINE_TYPE_WITH_CODE() or
|
|
G_DEFINE_ABSTRACT_TYPE_WITH_CODE().
|
|
|
|
For instance:
|
|
|
|
|[<!-- language="C" -->
|
|
typedef struct _MyObject MyObject;
|
|
typedef struct _MyObjectClass MyObjectClass;
|
|
|
|
typedef struct {
|
|
gint foo;
|
|
gint bar;
|
|
} MyObjectPrivate;
|
|
|
|
G_DEFINE_TYPE_WITH_CODE (MyObject, my_object, G_TYPE_OBJECT,
|
|
G_ADD_PRIVATE (MyObject))
|
|
]|
|
|
|
|
Will add MyObjectPrivate as the private data to any instance of the MyObject
|
|
type.
|
|
|
|
G_DEFINE_TYPE_* macros will automatically create a private function
|
|
based on the arguments to this macro, which can be used to safely
|
|
retrieve the private data from an instance of the type; for instance:
|
|
|
|
|[<!-- language="C" -->
|
|
gint
|
|
my_object_get_foo (MyObject *obj)
|
|
{
|
|
MyObjectPrivate *priv = my_object_get_instance_private (obj);
|
|
|
|
g_return_val_if_fail (MY_IS_OBJECT (obj), 0);
|
|
|
|
return priv->foo;
|
|
}
|
|
|
|
void
|
|
my_object_set_bar (MyObject *obj,
|
|
gint bar)
|
|
{
|
|
MyObjectPrivate *priv = my_object_get_instance_private (obj);
|
|
|
|
g_return_if_fail (MY_IS_OBJECT (obj));
|
|
|
|
if (priv->bar != bar)
|
|
priv->bar = bar;
|
|
}
|
|
]|
|
|
|
|
Note that this macro can only be used together with the G_DEFINE_TYPE_*
|
|
macros, since it depends on variable names from those macros.
|
|
|
|
Also note that private structs added with these macros must have a struct
|
|
name of the form `TypeNamePrivate`.
|
|
|
|
It is safe to call the `_get_instance_private` function on %NULL or invalid
|
|
objects since it's only adding an offset to the instance pointer. In that
|
|
case the returned pointer must not be dereferenced.</doc>

|
|
<doc xml:space="preserve">#GBinding is the representation of a binding between a property on a
|
|
#GObject instance (or source) and another property on another #GObject
|
|
instance (or target). Whenever the source property changes, the same
|
|
value is applied to the target property; for instance, the following
|
|
binding:
|
|
|
|
|[<!-- language="C" -->
|
|
g_object_bind_property (object1, "property-a",
|
|
object2, "property-b",
|
|
G_BINDING_DEFAULT);
|
|
]|
|
|
|
|
will cause the property named "property-b" of @object2 to be updated
|
|
every time g_object_set() or the specific accessor changes the value of
|
|
the property "property-a" of @object1.
|
|
|
|
It is possible to create a bidirectional binding between two properties
|
|
of two #GObject instances, so that if either property changes, the
|
|
other is updated as well, for instance:
|
|
|
|
|[<!-- language="C" -->
|
|
g_object_bind_property (object1, "property-a",
|
|
object2, "property-b",
|
|
G_BINDING_BIDIRECTIONAL);
|
|
]|
|
|
|
|
will keep the two properties in sync.
|
|
|
|
It is also possible to set a custom transformation function (in both
|
|
directions, in case of a bidirectional binding) to apply a custom
|
|
transformation from the source value to the target value before
|
|
applying it; for instance, the following binding:
|
|
|
|
|[<!-- language="C" -->
|
|
g_object_bind_property_full (adjustment1, "value",
|
|
adjustment2, "value",
|
|
G_BINDING_BIDIRECTIONAL,
|
|
celsius_to_fahrenheit,
|
|
fahrenheit_to_celsius,
|
|
NULL, NULL);
|
|
]|
|
|
|
|
will keep the "value" property of the two adjustments in sync; the
|
|
@celsius_to_fahrenheit function will be called whenever the "value"
|
|
property of @adjustment1 changes and will transform the current value
|
|
of the property before applying it to the "value" property of @adjustment2.
|
|
|
|
Vice versa, the @fahrenheit_to_celsius function will be called whenever
|
|
the "value" property of @adjustment2 changes, and will transform the
|
|
current value of the property before applying it to the "value" property
|
|
of @adjustment1.
|
|
|
|
Note that #GBinding does not resolve cycles by itself; a cycle like
|
|
|
|
|[
|
|
object1:propertyA -> object2:propertyB
|
|
object2:propertyB -> object3:propertyC
|
|
object3:propertyC -> object1:propertyA
|
|
]|
|
|
|
|
might lead to an infinite loop. The loop, in this particular case,
|
|
can be avoided if the objects emit the #GObject::notify signal only
|
|
if the value has effectively been changed. A binding is implemented
|
|
using the #GObject::notify signal, so it is susceptible to all the
|
|
various ways of blocking a signal emission, like g_signal_stop_emission()
|
|
or g_signal_handler_block().
|
|
|
|
A binding will be severed, and the resources it allocates freed, whenever
|
|
either one of the #GObject instances it refers to are finalized, or when
|
|
the #GBinding instance loses its last reference.
|
|
|
|
Bindings for languages with garbage collection can use
|
|
g_binding_unbind() to explicitly release a binding between the source
|
|
and target properties, instead of relying on the last reference on the
|
|
binding, source, and target instances to drop.

<doc xml:space="preserve">A callback function used by the type system to initialize the class

|
of a specific type. This function should initialize all static class
|
|
members.
|
|
|
|
The initialization process of a class involves:
|
|
|
|
- Copying common members from the parent class over to the
|
|
derived class structure.
|
|
- Zero initialization of the remaining members not copied
|
|
over from the parent class.
|
|
- Invocation of the GBaseInitFunc() initializers of all parent
|
|
types and the class' type.
|
|
- Invocation of the class' GClassInitFunc() initializer.
|
|
|
|
Since derived classes are partially initialized through a memory copy
|
|
of the parent class, the general rule is that GBaseInitFunc() and
|
|
GBaseFinalizeFunc() should take care of necessary reinitialization
|
|
and release of those class members that were introduced by the type
|
|
that specified these GBaseInitFunc()/GBaseFinalizeFunc().
|
|
GClassInitFunc() should only care about initializing static
|
|
class members, while dynamic class members (such as allocated strings

|

|
]|
|
|
Initialization of TypeBClass will first cause initialization of
|
|
TypeAClass (derived classes reference their parent classes, see
|
|
g_type_class_ref() on this).
|
|
|
|
Initialization of TypeAClass roughly involves zero-initializing its fields,
|
|
then calling its GBaseInitFunc() type_a_base_class_init() to allocate
|
|
its dynamic members (dynamic_string), and finally calling its GClassInitFunc()
|
|
type_a_class_init() to initialize its static members (static_integer).
|
|
The first step in the initialization process of TypeBClass is then
|
|
a plain memory copy of the contents of TypeAClass into TypeBClass and
|
|
zero-initialization of the remaining fields in TypeBClass.
|
|
The dynamic members of TypeAClass within TypeBClass now need
|
|
reinitialization which is performed by calling type_a_base_class_init()
|
|
with an argument of TypeBClass.
|
|
|
|
After that, the GBaseInitFunc() of TypeBClass, type_b_base_class_init()
|
|
is called to allocate the dynamic members of TypeBClass (dynamic_gstring),
|
|
and finally the GClassInitFunc() of TypeBClass, type_b_class_init(),
|
|
is called to complete the initialization process with the static members
|
|
(static_float).
|
|
|
|
Corresponding finalization counter parts to the GBaseInitFunc() functions
|
|
have to be provided to release allocated resources at class finalization
|
|
time.</doc>

<doc xml:space="preserve">A #GClosure represents a callback supplied by the programmer. It
|
|
will generally comprise a function of some kind and a marshaller
|
|
used to call it. It is the responsibility of the marshaller to
|
|
convert the arguments for the invocation from #GValues into
|
|
a suitable form, perform the callback on the converted arguments,
|
|
and transform the return value back into a #GValue.
|
|
|
|
In the case of C programs, a closure usually just holds a pointer
|
|
to a function and maybe a data argument, and the marshaller
|
|
converts between #GValue and native C types. The GObject
|
|
library provides the #GCClosure type for this purpose. Bindings for
|
|
other languages need marshallers which convert between #GValues
|
|
and suitable representations in the runtime of the language in
|
|
order to use functions written in that language as callbacks. Use
|
|
g_closure_set_marshal() to set the marshaller on such a custom
|
|
closure implementation.
|
|
|
|
Within GObject, closures play an important role in the
|
|
implementation of signals. When a signal is registered, the
|
|
@c_marshaller argument to g_signal_new() specifies the default C
|
|
marshaller for any closure which is connected to this
|
|
signal. GObject provides a number of C marshallers for this
|
|
purpose, see the g_cclosure_marshal_*() functions. Additional C
|
|
marshallers can be generated with the [glib-genmarshal][glib-genmarshal]
|
|
utility. Closures can be explicitly connected to signals with
|
|
g_signal_connect_closure(), but it usually more convenient to let
|
|
GObject create a closure automatically by using one of the
|
|
g_signal_connect_*() functions which take a callback function/user
|
|
data pair.
|
|
|
|
Using closures has a number of important advantages over a simple
|
|
callback function/data pointer combination:
|
|
|
|
- Closures allow the callee to get the types of the callback parameters,
|
|
which means that language bindings don't have to write individual glue
|
|
for each callback type.
|
|
|
|
- The reference counting of #GClosure makes it easy to handle reentrancy
|
|
right; if a callback is removed while it is being invoked, the closure
|
|
and its parameters won't be freed until the invocation finishes.
|
|
|
|
- g_closure_invalidate() and invalidation notifiers allow callbacks to be
|
|
automatically removed when the objects they point to go away.</doc>

The same marshallers (generated by [glib-genmarshal][glib-genmarshal]),

the right callback and passes it to the marshaller as the

<doc xml:space="preserve">Takes over the initial ownership of a closure. Each closure is
|
|
initially created in a "floating" state, which means that the initial
|
|
reference count is not owned by any caller. g_closure_sink() checks
|
|
to see if the object is still floating, and if so, unsets the
|
|
floating state and decreases the reference count. If the closure
|
|
is not floating, g_closure_sink() does nothing. The reason for the
|
|
existence of the floating state is to prevent cumbersome code
|
|
sequences like:
|
|
|[<!-- language="C" -->
|
|
closure = g_cclosure_new (cb_func, cb_data);
|
|
g_source_set_closure (source, closure);
|
|
g_closure_unref (closure); // GObject doesn't really need this
|
|
]|
|
|
Because g_source_set_closure() (and similar functions) take ownership of the
|
|
initial reference count, if it is unowned, we instead can write:
|
|
|[<!-- language="C" -->
|
|
g_source_set_closure (source, g_cclosure_new (cb_func, cb_data));
|
|
]|
|
|
|
|
Generally, this function is used together with g_closure_ref(). Ane example
|
|
of storing a closure for later notification looks like:
|
|
|[<!-- language="C" -->
|
|
static GClosure *notify_closure = NULL;
|
|
void
|
|
foo_notify_set_closure (GClosure *closure)
|
|
{
|
|
if (notify_closure)
|
|
g_closure_unref (notify_closure);
|
|
notify_closure = closure;
|
|
if (notify_closure)
|
|
{
|
|
g_closure_ref (notify_closure);
|
|
g_closure_sink (notify_closure);
|
|
}
|
|
}
|
|
]|
|
|
|
|
Because g_closure_sink() may decrement the reference count of a closure
|
|
(if it hasn't been called on @closure yet) just like g_closure_unref(),
|
|
g_closure_ref() should be called prior to this function.</doc>

<doc xml:space="preserve">A convenience macro for emitting the usual declarations in the
|
|
header file for a type which is intended to be subclassed.
|
|
|
|
You might use it in a header as follows:
|
|
|
|
|[
|
|
#ifndef _gtk_frobber_h_
|
|
#define _gtk_frobber_h_
|
|
|
|
#define GTK_TYPE_FROBBER gtk_frobber_get_type ()
|
|
GDK_AVAILABLE_IN_3_12
|
|
G_DECLARE_DERIVABLE_TYPE (GtkFrobber, gtk_frobber, GTK, FROBBER, GtkWidget)
|
|
|
|
struct _GtkFrobberClass
|
|
{
|
|
GtkWidgetClass parent_class;
|
|
|
|
void (* handle_frob) (GtkFrobber *frobber,
|
|
guint n_frobs);
|
|
|
|
gpointer padding[12];
|
|
};
|
|
|
|
GtkWidget * gtk_frobber_new (void);
|
|
|
|
...
|
|
|
|
#endif
|
|
]|
|
|
|
|
This results in the following things happening:
|
|
|
|
- the usual gtk_frobber_get_type() function is declared with a return type of #GType
|
|
|
|
- the GtkFrobber struct is created with GtkWidget as the first and only item. You are expected to use
|
|
a private structure from your .c file to store your instance variables.
|
|
|
|
- the GtkFrobberClass type is defined as a typedef to struct _GtkFrobberClass, which is left undefined.
|
|
You should do this from the header file directly after you use the macro.
|
|
|
|
- the GTK_FROBBER() and GTK_FROBBER_CLASS() casts are emitted as static inline functions along with
|
|
the GTK_IS_FROBBER() and GTK_IS_FROBBER_CLASS() type checking functions and GTK_FROBBER_GET_CLASS()
|
|
function.
|
|
|
|
- g_autoptr() support being added for your type, based on the type of your parent class
|
|
|
|
You can only use this function if your parent type also supports g_autoptr().
|
|
|
|
Because the type macro (GTK_TYPE_FROBBER in the above example) is not a callable, you must continue to
|
|
manually define this as a macro for yourself.
|
|
|
|
The declaration of the _get_type() function is the first thing emitted by the macro. This allows this macro
|
|
to be used in the usual way with export control and API versioning macros.
|
|
|
|
If you are writing a library, it is important to note that it is possible to convert a type from using
|
|
G_DECLARE_FINAL_TYPE() to G_DECLARE_DERIVABLE_TYPE() without breaking API or ABI. As a precaution, you
|
|
should therefore use G_DECLARE_FINAL_TYPE() until you are sure that it makes sense for your class to be
|
|
subclassed. Once a class structure has been exposed it is not possible to change its size or remove or
|
|
reorder items without breaking the API and/or ABI. If you want to declare your own class structure, use
|
|
G_DECLARE_DERIVABLE_TYPE(). If you want to declare a class without exposing the class or instance
|
|
structures, use G_DECLARE_FINAL_TYPE().
|
|
|
|
If you must use G_DECLARE_DERIVABLE_TYPE() you should be sure to include some padding at the bottom of your
|
|
class structure to leave space for the addition of future virtual functions.</doc>

convenience of the person defining the type and should not be considered to be part of the ABI. In

<doc xml:space="preserve">A convenience macro for type implementations, which declares a class
|
|
initialization function, an instance initialization function (see #GTypeInfo
|
|
for information about these), a static variable named `t_n_parent_class`
|
|
pointing to the parent class, and adds private instance data to the type.
|
|
Furthermore, it defines a *_get_type() function. See G_DEFINE_TYPE_EXTENDED()
|
|
for an example.
|
|
|
|
Note that private structs added with this macros must have a struct
|
|
name of the form @TN Private.
|
|
|
|
The private instance data can be retrieved using the automatically generated
|
|
getter function `t_n_get_instance_private()`.

Note that in C, small integer types in variable argument lists are promoted
|

up to #gint or #guint as appropriate, and read back accordingly. #gint is 32

bits on every platform on which GLib is currently supported. This means that
|
|
you can use C expressions of type #gint with g_object_new() and properties of
|
|
type #gint or #guint or smaller. Specifically, you can use integer literals
|
|
with these property types.
|
|
|
|
When using property types of #gint64 or #guint64, you must ensure that the
|
|
value that you provide is 64 bit. This means that you should use a cast or
|
|
make use of the %G_GINT64_CONSTANT or %G_GUINT64_CONSTANT macros.
|
|
|
|
Similarly, #gfloat is promoted to #gdouble, so you must ensure that the value
|
|
you provide is a #gdouble, even for a property of type #gfloat.</doc>

<doc xml:space="preserve">Increases the reference count of the object by one and sets a
|
|
callback to be called when all other references to the object are
|
|
dropped, or when this is already the last reference to the object
|
|
and another reference is established.
|
|
|
|
This functionality is intended for binding @object to a proxy
|
|
object managed by another memory manager. This is done with two
|
|
paired references: the strong reference added by
|
|
g_object_add_toggle_ref() and a reverse reference to the proxy
|
|
object which is either a strong reference or weak reference.
|
|
|
|
The setup is that when there are no other references to @object,
|
|
only a weak reference is held in the reverse direction from @object
|
|
to the proxy object, but when there are other references held to
|
|
@object, a strong reference is held. The @notify callback is called
|
|
when the reference from @object to the proxy object should be
|
|
"toggled" from strong to weak (@is_last_ref true) or weak to strong
|
|
(@is_last_ref false).
|
|
|
|
Since a (normal) reference must be held to the object before
|
|
calling g_object_add_toggle_ref(), the initial state of the reverse
|
|
link is always strong.
|
|
|
|
Multiple toggle references may be added to the same gobject,
|
|
however if there are multiple toggle references to an object, none
|
|
of them will ever be notified until all but one are removed. For
|
|
this reason, you should only ever use a toggle reference if there
|
|
is important state in the proxy object.</doc>

Creates a binding between @source_property on @source and @target_property
|
|
on @target, allowing you to set the transformation functions to be used by
|
|
the binding.
|
|
|
|
If @flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
|
|
if @target_property on @target changes then the @source_property on @source
|
|
will be updated as well. The @transform_from function is only used in case
|
|
of bidirectional bindings, otherwise it will be ignored
|
|
|
|
The binding will automatically be removed when either the @source or the
|
|
@target instances are finalized. This will release the reference that is
|
|
being held on the #GBinding instance; if you want to hold on to the
|
|
#GBinding instance, you will need to hold a reference to it.
|
|
|
|
To remove the binding, call g_binding_unbind().
|
|
|
|
A #GObject can have multiple bindings.
|
|
|
|
The same @user_data parameter will be used for both @transform_to
|
|
and @transform_from transformation functions; the @notify function will
|
|
be called once, when the binding is removed. If you need different data
|
|
for each transformation function, please use
|
|
g_object_bind_property_with_closures() instead.</doc>

Usually, calling this function is only required to update

user data pointers with a destroy notifier, for example:

object_add_to_user_list (GObject *object,

const gchar *new_string)

// retrive the old string list
|
|
GList *list = g_object_steal_qdata (object, quark_string_list);
|
|
|
|
// prepend new string
|
|
list = g_list_prepend (list, g_strdup (new_string));
|

// this changed 'list', so we need to set it again

g_object_set_qdata_full (object, quark_string_list, list, free_string_list);

g_list_free (list);
|
|
}
|
|
]|
|
|
Using g_object_get_qdata() in the above example, instead of
|
|
g_object_steal_qdata() would have left the destroy function set,

and thus the partial string list would have been freed upon

g_object_set_qdata_full().</doc>

its value set through g_object_set_property(), g_object_set(), et al.
|
|
|
|
Note that getting this signal doesn’t itself guarantee that the value of
|
|
the property has actually changed. When it is emitted is determined by the
|
|
derived GObject class. If the implementor did not create the property with
|
|
%G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results
|
|
in ::notify being emitted, even if the new value is the same as the old.
|
|
If they did pass %G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only
|
|
when they explicitly call g_object_notify() or g_object_notify_by_pspec(),
|
|
and common practice is to do that only when the value has actually changed.
|
|
|
|
This signal is typically used to obtain change notification for a
|
|
single property, by specifying the property name as a detail in the

|
g_signal_connect() call, like this:

All properties should be installed during the class initializer. It

is possible to install properties after that, but doing so is not

|
recommend, and specifically, is not guaranteed to be thread-safe vs.
|
|
use of properties on the same type on other threads.
|
|
|
|
The property id of each property is the index of each #GParamSpec in

the @pspecs array.
|
|
|
|
The property id of 0 is treated specially by #GObject and it should not
|

be used to store a #GParamSpec.

This function should be used if you plan to use a static array of
|
|
#GParamSpecs and g_object_notify_by_pspec(). For instance, this
|
|
class initialization:
|
|
|
|
|[<!-- language="C" -->

enum {

PROP_0, PROP_FOO, PROP_BAR, N_PROPERTIES
|
|
};

|

static void

|
my_object_class_init (MyObjectClass *klass)
|

{

|
|
obj_properties[PROP_FOO] =
|
|
g_param_spec_int ("foo", "Foo", "Foo",
|

-1, G_MAXINT,
|
|
0,
|

G_PARAM_READWRITE);
|
|

obj_properties[PROP_BAR] =

g_param_spec_string ("bar", "Bar", "Bar",

G_PARAM_READWRITE);

This allows this class to "override" a property implementation in

a parent class or to provide the implementation of a property from
|
|
an interface.
|
|
|
|
Internally, overriding is implemented by creating a property of type
|
|
#GParamSpecOverride; generally operations that query the properties of
|
|
the object class, such as g_object_class_find_property() or
|
|
g_object_class_list_properties() will return the overridden
|
|
property. However, in one case, the @construct_properties argument of
|
|
the @constructor virtual function, the #GParamSpecOverride is passed
|
|
instead, so that the @param_id field of the #GParamSpec will be
|
|
correct. For virtually all uses, this makes no difference. If you
|
|
need to get the overridden property, you can call

g_param_spec_get_redirect_target().</doc>

<doc xml:space="preserve">#GParamSpec is an object structure that encapsulates the metadata

required to specify parameters, such as e.g. #GObject properties.
|
|
|
|
## Parameter names # {#canonical-parameter-names}
|
|
|
|
A property name consists of segments consisting of ASCII letters and
|
|
digits, separated by either the `-` or `_` character. The first
|
|
character of a property name must be a letter. These are the same rules as
|
|
for signal naming (see g_signal_new()).
|
|
|
|
When creating and looking up a #GParamSpec, either separator can be
|
|
used, but they cannot be mixed. Using `-` is considerably more
|
|
efficient, and is the ‘canonical form’. Using `_` is discouraged.</doc>

See [canonical parameter names][canonical-parameter-names] for details of

the rules for @name. Names which violate these rules lead to undefined

|
behaviour.
|
|
|
|
Beyond the name, #GParamSpecs have two more descriptive
|
|
strings associated with them, the @nick, which should be suitable
|
|
for use as a label for the property in a property editor, and the
|
|
@blurb, which should be a somewhat longer description, suitable for
|
|
e.g. a tooltip. The @nick and @blurb should ideally be localized.</doc>

When an object is allocated, the private structures for
|
|
the type and all of its parent types are allocated
|
|
sequentially in the same memory block as the public
|
|
structures, and are zero-filled.
|

a type and all its parent types cannot exceed 64 KiB.

|
|
MyObjectPrivate to an object MyObject defined in the standard

GObject fashion in the type's class_init() function.

of repeatedly calling MY_OBJECT_GET_PRIVATE().

<doc xml:space="preserve">#GTypeModule provides a simple implementation of the #GTypePlugin
|
|
interface. The model of #GTypeModule is a dynamically loaded module
|
|
which implements some number of types and interface implementations.
|
|
When the module is loaded, it registers its types and interfaces
|
|
using g_type_module_register_type() and g_type_module_add_interface().
|
|
As long as any instances of these types and interface implementations
|
|
are in use, the module is kept loaded. When the types and interfaces
|
|
are gone, the module may be unloaded. If the types and interfaces
|
|
become used again, the module will be reloaded. Note that the last
|
|
unref cannot happen in module code, since that would lead to the
|
|
caller's code being unloaded before g_object_unref() returns to it.
|
|
|
|
Keeping track of whether the module should be loaded or not is done by
|
|
using a use count - it starts at zero, and whenever it is greater than
|
|
zero, the module is loaded. The use count is maintained internally by
|
|
the type system, but also can be explicitly controlled by
|
|
g_type_module_use() and g_type_module_unuse(). Typically, when loading
|
|
a module for the first type, g_type_module_use() will be used to load
|
|
it so that it can initialize its types. At some later point, when the
|
|
module no longer needs to be loaded except for the type
|
|
implementations it contains, g_type_module_unuse() is called.
|
|
|
|
#GTypeModule does not actually provide any implementation of module
|
|
loading and unloading. To create a particular module type you must
|
|
derive from #GTypeModule and implement the load and unload functions
|

in #GTypeModuleClass.</doc>

|
|
<doc xml:space="preserve">The GObject type system supports dynamic loading of types.
|
|
The #GTypePlugin interface is used to handle the lifecycle
|
|
of dynamically loaded types. It goes as follows:
|
|
|
|
1. The type is initially introduced (usually upon loading the module
|
|
the first time, or by your main application that knows what modules
|
|
introduces what types), like this:
|
|
|[<!-- language="C" -->
|
|
new_type_id = g_type_register_dynamic (parent_type_id,
|
|
"TypeName",
|
|
new_type_plugin,
|
|
type_flags);
|
|
]|
|
|
where @new_type_plugin is an implementation of the
|
|
#GTypePlugin interface.
|
|
|
|
2. The type's implementation is referenced, e.g. through
|
|
g_type_class_ref() or through g_type_create_instance() (this is
|
|
being called by g_object_new()) or through one of the above done on
|
|
a type derived from @new_type_id.
|
|
|
|
3. This causes the type system to load the type's implementation by
|
|
calling g_type_plugin_use() and g_type_plugin_complete_type_info()
|
|
on @new_type_plugin.
|
|
|
|
4. At some point the type's implementation isn't required anymore,
|
|
e.g. after g_type_class_unref() or g_type_free_instance() (called
|
|
when the reference count of an instance drops to zero).
|
|
|
|
5. This causes the type system to throw away the information retrieved
|
|
from g_type_plugin_complete_type_info() and then it calls
|
|
g_type_plugin_unuse() on @new_type_plugin.
|
|
|
|
6. Things may repeat from the second step.
|
|
|
|
So basically, you need to implement a #GTypePlugin type that
|
|
carries a use_count, once use_count goes from zero to one, you need
|
|
to load the implementation to successfully handle the upcoming
|
|
g_type_plugin_complete_type_info() call. Later, maybe after
|
|
succeeding use/unuse calls, once use_count drops to zero, you can
|
|
unload the implementation again. The type system makes sure to call
|
|
g_type_plugin_use() and g_type_plugin_complete_type_info() again
|
|
when the type is needed again.
|
|
|
|
#GTypeModule is an implementation of #GTypePlugin that already
|
|
implements most of this except for the actual module loading and
|
|
unloading. It even handles multiple registered types per module.</doc>

this value bit-by-bit. Each character in the format represents

an argument to be collected, and the characters themselves indicate

the type of the argument. Currently supported arguments are:
|
|
- 'i' - Integers. passed as collect_values[].v_int.
|
|
- 'l' - Longs. passed as collect_values[].v_long.
|
|
- 'd' - Doubles. passed as collect_values[].v_double.
|
|
- 'p' - Pointers. passed as collect_values[].v_pointer.
|
|
It should be noted that for variable argument list construction,
|
|
ANSI C promotes every type smaller than an integer to an int, and
|
|
floats to doubles. So for collection of short int or char, 'i'
|
|
needs to be used, and for collection of floats 'd'.</doc>

A signal name consists of segments consisting of ASCII letters and
|
|
digits, separated by either the `-` or `_` character. The first
|
|
character of a signal name must be a letter. Names which violate these
|
|
rules lead to undefined behaviour. These are the same rules as for property
|
|
naming (see g_param_spec_internal()).
|
|
|
|
When registering a signal and looking up a signal, either separator can
|
|
be used, but they cannot be mixed. Using `-` is considerably more efficient.
|
|
Using `_` is discouraged.
|
|
|
|
If 0 is used for @class_offset subclasses cannot override the class handler
|
|
in their class_init method by doing super_class->signal_handler = my_signal_handler.
|
|
Instead they will have to use g_signal_override_class_handler().
|
|
|
|
If @c_marshaller is %NULL, g_cclosure_marshal_generic() will be used as
|
|
the marshaller for this signal. In some simple cases, g_signal_new()
|
|
will use a more optimized c_marshaller and va_marshaller for the signal
|
|
instead of g_cclosure_marshal_generic().
|
|
|
|
If @c_marshaller is non-%NULL, you need to also specify a va_marshaller
|

In theory, simply calling the type's _get_type() method (or using
|
|
the corresponding macro) is supposed take care of this. However,
|
|
_get_type() methods are often marked %G_GNUC_CONST for performance
|
|
reasons, even though this is technically incorrect (since
|
|
%G_GNUC_CONST requires that the function not have side effects,
|
|
which _get_type() methods do on the first call). As a result, if
|
|
you write a bare call to a _get_type() macro, it may get optimized
|
|
out by the compiler. Using g_type_ensure() guarantees that the

type's _get_type() method is called.</doc>
