Sets our main struct and passes it to the parent class.
A destructor is present on this object, but not explicitly documented in the source.
Get the short description of a gobject.ParamSpec
Gets the default value of pspec as a pointer to a gobject.Value
Get the name of a gobject.ParamSpec
Gets the GQuark for the name.
Get the nickname of a gobject.ParamSpec
Get the main Gtk struct
Gets back user data pointers stored via ParamSpec.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 GParamSpecOverride See ObjectClass.overrideProperty for an example of the use of this capability.
the main Gtk struct as a void*
Convenience function to ref and sink a gobject.ParamSpec
Increments the reference count of pspec.
Sets an opaque, named pointer on a gobject.ParamSpec 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 ParamSpec.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 ParamSpec.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 ParamSpec.setQdata with the same quark.
The initial reference count of a newly created gobject.ParamSpec is 1, even though no one has explicitly called ParamSpec.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 ParamSpec.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.
Creates a new gobject.ParamSpec instance.
Registers name as the name of a new static type derived from G_TYPE_PARAM The type system uses the information contained in the GParamSpecTypeInfo structure pointed to by info to manage the gobject.ParamSpec type and its instances.
Transforms src_value into dest_value if possible, and then validates dest_value, in order for it to conform to pspec. If strict_validation is TRUE this function will only succeed if the transformed dest_value complied to pspec without modifications.
Checks whether value contains the default value as specified in pspec.
Sets value to its default value as specified in pspec.
Ensures that the contents of value comply with the specifications set out by pspec. For example, a GParamSpecInt might require that integers stored in value may not be smaller than -42 and not be greater than +42. If value contains an integer outside of this range, it is modified accordingly, so the resulting value will fit into the range -42 .. +42.
Compares value1 with value2 according to pspec, and return -1, 0 or +1, if value1 is found to be less than, equal to or greater than value2, respectively.
the main Gtk struct
gobject.ParamSpec is an object structure that encapsulates the metadata required to specify parameters, such as e.g. GObject properties.
Parameter names # {[canonical-parameter-name|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 gobject.ParamSpec, either separator can be used, but they cannot be mixed. Using - is considerably more efficient, and is the ‘canonical form’. Using _ is discouraged.
