Struct GObject.ParamSpec

Import line:	GObject = imports.gi.GObject;
GIR File:	GObject-2.0.gir
C documentation:	GParamSpec
Struct :	ParamSpec

GParamSpec is an object structure that encapsulates the metadata
required to specify parameters, such as e.g. GObject properties.

Parameter names need to start with a letter (a-z or A-Z). Subsequent
characters can be letters, numbers or a '-'.
All other characters are replaced by a '-' during construction.
The result of this replacement is called the canonical name of the
parameter.

Methods / Constructors
Method / Constructor		Defined By
	new GObject.ParamSpec () Create a new GObject.ParamSpec Create a new GObject.ParamSpec
	get_blurb () : String Get the short description of a GParamSpec. Get the short description of a GParamSpec. Returns: String the short description of pspec.	GObject.ParamSpec
	get_name () : String Get the name of a GParamSpec. Get the name of a GParamSpec. Returns: String the name of pspec.	GObject.ParamSpec
	get_nick () : String Get the nickname of a GParamSpec. Get the nickname of a GParamSpec. Returns: String the nickname of pspec.	GObject.ParamSpec
	get_qdata (guint32 *quark) : void Gets back user data pointers stored via g_param_spec_set_qdata(). Gets back user data pointers stored via g_param_spec_set_qdata(). Parameters: guint32 quark Required (not null) a GQuark, naming the user data pointer Returns: void* the user data pointer set, or NULL	GObject.ParamSpec
	get_redirect_target () : GObject.ParamSpec If the paramspec redirects operations to another paramspec, returns that paramspec. If the paramspec redirects operations to another paramspec, returns that paramspec. Redirect is used typically for providing a new implementation of a property in a derived type while preserving all the properties from the parent type. Redirection is established by creating a property of type GParamSpecOverride. See g_object_class_override_property() for an example of the use of this capability. paramspec should be redirected, or NULL if none. Returns: GObject.ParamSpec paramspec to which requests on this	GObject.ParamSpec
	set_qdata (guint32 *quark, void *data) : none Sets an opaque, named pointer on a GParamSpec. Sets an opaque, named pointer on a GParamSpec. The name is specified through a GQuark* (retrieved e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the pspec with g_param_spec_get_qdata(). Setting a previously set user data pointer, overrides (frees) the old pointer set, using NULL as pointer essentially removes the data stored. Parameters: guint32 quark Required (not null) a GQuark, naming the user data pointer void* data Required (not null) an opaque user data pointer Returns: none	GObject.ParamSpec
	sink () : none The initial reference count of a newly created GParamSpec is 1, even though no one has explicitly called g_param_spec_ref() on it yet. The initial reference count of a newly created GParamSpec is 1, even though no one has explicitly called g_param_spec_ref() on it yet. So the initial reference count is flagged as "floating", until someone calls g_param_spec_ref (pspec); g_param_spec_sink (pspec); in sequence on it, taking over the initial reference count (thus ending up with a pspec that has a reference count of 1 still, but is not flagged "floating" anymore). Returns: none	GObject.ParamSpec
	steal_qdata (guint32 *quark) : void Gets back user data pointers stored via g_param_spec_set_qdata() and removes the data from pspec without invoking its destroy() function (if any was set). Gets back user data pointers stored via g_param_spec_set_qdata() and removes the data from pspec without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier. Parameters: guint32 quark Required (not null) a GQuark, naming the user data pointer Returns: void* the user data pointer set, or NULL	GObject.ParamSpec
