Description

A ParamSpecPool maintains a collection of GParamSpecs which can be quickly accessed by owner and name. The implementation of the Object property system uses such a pool to store the GParamSpecs of the properties all object types.

Synopsis

newtype ParamSpecPool = ParamSpecPool (ManagedPtr ParamSpecPool)
paramSpecPoolInsert :: (HasCallStack, MonadIO m) => ParamSpecPool -> GParamSpec -> GType -> m ()
paramSpecPoolListOwned :: (HasCallStack, MonadIO m) => ParamSpecPool -> GType -> m [GParamSpec]
paramSpecPoolLookup :: (HasCallStack, MonadIO m) => ParamSpecPool -> Text -> GType -> Bool -> m GParamSpec
paramSpecPoolNew :: (HasCallStack, MonadIO m) => Bool -> m ParamSpecPool
paramSpecPoolRemove :: (HasCallStack, MonadIO m) => ParamSpecPool -> GParamSpec -> m ()

Methods

Overloaded methods

insert

paramSpecPoolInsert Source #

Arguments

:: (HasCallStack, MonadIO m)
=> ParamSpecPool	`pool`: a `ParamSpecPool`.
-> GParamSpec	`pspec`: the `ParamSpec` to insert
-> GType	`ownerType`: a `GType` identifying the owner of `pspec`
-> m ()

Inserts a ParamSpec in the pool.

listOwned

paramSpecPoolListOwned Source #

Arguments

:: (HasCallStack, MonadIO m)
=> ParamSpecPool	`pool`: a `ParamSpecPool`
-> GType	`ownerType`: the owner to look for
-> m [GParamSpec]	Returns: a `List` of all `GParamSpecs` owned by `ownerType` in the pool`GParamSpecs`.

Gets an List of all GParamSpecs owned by ownerType in the pool.

lookup

paramSpecPoolLookup Source #

Arguments

:: (HasCallStack, MonadIO m)
=> ParamSpecPool	`pool`: a `ParamSpecPool`
-> Text	`paramName`: the name to look for
-> GType	`ownerType`: the owner to look for
-> Bool	`walkAncestors`: If `True`, also try to find a `ParamSpec` with `paramName` owned by an ancestor of `ownerType`.
-> m GParamSpec	Returns: The found `ParamSpec`, or `Nothing` if no matching `ParamSpec` was found.

Looks up a ParamSpec in the pool.

new

paramSpecPoolNew Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Bool	`typePrefixing`: Whether the pool will support type-prefixed property names.
-> m ParamSpecPool	Returns: a newly allocated `ParamSpecPool`.

Creates a new ParamSpecPool.

If typePrefixing is True, lookups in the newly created pool will allow to specify the owner as a colon-separated prefix of the property name, like "GtkContainer:border-width". This feature is deprecated, so you should always set typePrefixing to False.

remove

paramSpecPoolRemove Source #

Arguments

:: (HasCallStack, MonadIO m)
=> ParamSpecPool	`pool`: a `ParamSpecPool`
-> GParamSpec	`pspec`: the `ParamSpec` to remove
-> m ()

Removes a ParamSpec from the pool.
