Creates a new T instance.

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. Names which violate these rules lead to undefined behaviour.

When creating and looking up a T, either separator can be used, but they cannot be mixed. Using '-' is considerably more efficient and in fact required when using property names as detail strings for signals.

Beyond the name, Ts 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.

Creates a new Gtk.GObject.GParamSpecBoxed.T instance specifying a G_TYPE_OBJECT derived property.

See Internal for details on property names.

Creates a new property of type Gtk.GObject.GParamSpecOverride.T. This is used to direct operations to another paramspec, and will not be directly useful unless you are implementing a new base type similar to GObject.

Creates a new Gtk.GObject.GParamSpecParam.T instance specifying a G_TYPE_PARAM property.

Creates a new Gtk.GObject.GParamSpecUnichar.T instance specifying a G_TYPE_UINT property. GValue structures for this property can be accessed with g_value_set_uint() and g_value_get_uint().

See Internal for details on property names.

Creates a new Gtk.GObject.GParamSpecValueArray.T instance specifying a G_TYPE_VALUE_ARRAY property. G_TYPE_VALUE_ARRAY is a G_TYPE_BOXED type, as such, GValue structures for this property can be accessed with g_value_set_boxed() and g_value_get_boxed().

Creates a new Gtk.GObject.GParamSpecVariant.T instance specifying a GVariant property.

If default_value is floating, it is consumed.

Get the short description of a T.

Get the name of a T.

The name is always an "interned" string (as per g_intern_string()). This allows for pointer-value comparisons.

Get the nickname of a T.

Gets back user data pointers stored via SetQdata.

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 Gtk.GObject.GParamSpecOverride.T. See g_object_class_override_property() for an example of the use of this capability.

Increments the reference count of pspec.

Convenience function to ref and sink a T.

Sets an opaque, named pointer on a T. The name is specified through a GQuark (retrieved e.g. via Gtk.Glib.GQuark.FromStaticString), and the pointer can be gotten back from the pspec with GetQdata. Setting a previously set user data pointer, overrides (frees) the old pointer set, using NULL as pointer essentially removes the data stored.

This function works like SetQdata, but in addition, a void (*destroy) (gpointer) function may be specified which is called with data as argument when the pspec is finalized, or the data is being overwritten by a call to SetQdata with the same quark.

The initial reference count of a newly created T is 1, even though no one has explicitly called 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).

Gets back user data pointers stored via SetQdata 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.

Decrements the reference count of a pspec.
