Get the short description of a GParamSpec.
Gets the default value of pspec as a pointer to a GValue.
Get the name of a GParamSpec.
Gets the GQuark for the name.
Get the nickname of a GParamSpec.
Gets back user data pointers stored via g_param_spec_set_qdata().
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.
Increments the reference count of pspec.
Convenience function to ref and sink 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.
This function works like g_param_spec_set_qdata(), 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
g_param_spec_set_qdata() with the same quark.
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).
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.
Decrements the reference count of a pspec.
