findProperty

public ParamSpec findProperty(@Nonnull
 Str property_name)

Looks up the #GParamSpec for a property of a class.

Parameters:

property_name - the name of the property to look up

Returns:

the #GParamSpec for the property, or %NULL if the class doesn't have a property of that name

findProperty

public ParamSpec findProperty(String property_name)

Looks up the #GParamSpec for a property of a class.

Parameters:

property_name - the name of the property to look up

Returns:

the #GParamSpec for the property, or %NULL if the class doesn't have a property of that name

installProperty

public void installProperty(int property_id,
 @Nonnull
 ParamSpec pspec)

Installs a new property.

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.

Note that it is possible to redefine a property in a derived class,
by installing a property with the same name. This can be useful at times,
e.g. to change the range of allowed values or the default value.

Parameters:

property_id - the id for the new property

pspec - the #GParamSpec for the new property

overrideProperty

public void overrideProperty(int property_id,
 @Nonnull
 Str name)

Registers @property_id as referring to a property with the name
@name in a parent class or in an interface implemented by @oclass.
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().

Parameters:

property_id - the new property ID

name - the name of a property registered in a parent class or in an interface of this class.

overrideProperty

public void overrideProperty(int property_id,
 String name)

Registers @property_id as referring to a property with the name
@name in a parent class or in an interface implemented by @oclass.
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().

Parameters:

property_id - the new property ID

name - the name of a property registered in a parent class or in an interface of this class.
