GI.GObject.Structs.ParamSpecTypeInfo

This structure is used to provide the type system with the information required to initialize and destruct (finalize) a parameter's class and instances thereof. The initialized structure is passed to the paramTypeRegisterStatic The type system will perform a deep copy of this structure, so its memory does not need to be persistent across invocation of paramTypeRegisterStatic.

Methods

Properties

finalize

No description available in the introspection data.

clearParamSpecTypeInfoFinalize :: MonadIO m => ParamSpecTypeInfo -> m ()

Set the value of the “finalize” field to Nothing. When overloading is enabled, this is equivalent to

clear #finalize

getParamSpecTypeInfoFinalize :: MonadIO m => ParamSpecTypeInfo -> m (Maybe ParamSpecTypeInfoFinalizeFieldCallback)

Get the value of the “finalize” field. When overloading is enabled, this is equivalent to

get paramSpecTypeInfo #finalize

setParamSpecTypeInfoFinalize :: MonadIO m => ParamSpecTypeInfo -> FunPtr C_ParamSpecTypeInfoFinalizeFieldCallback -> m ()

Set the value of the “finalize” field. When overloading is enabled, this is equivalent to

set paramSpecTypeInfo [ #finalize := value ]

instanceInit

No description available in the introspection data.

clearParamSpecTypeInfoInstanceInit :: MonadIO m => ParamSpecTypeInfo -> m ()

Set the value of the “instance_init” field to Nothing. When overloading is enabled, this is equivalent to

clear #instanceInit

getParamSpecTypeInfoInstanceInit :: MonadIO m => ParamSpecTypeInfo -> m (Maybe ParamSpecTypeInfoInstanceInitFieldCallback)

Get the value of the “instance_init” field. When overloading is enabled, this is equivalent to

get paramSpecTypeInfo #instanceInit

setParamSpecTypeInfoInstanceInit :: MonadIO m => ParamSpecTypeInfo -> FunPtr C_ParamSpecTypeInfoInstanceInitFieldCallback -> m ()

Set the value of the “instance_init” field. When overloading is enabled, this is equivalent to

set paramSpecTypeInfo [ #instanceInit := value ]

instanceSize

Size of the instance (object) structure.

getParamSpecTypeInfoInstanceSize :: MonadIO m => ParamSpecTypeInfo -> m Word16

Get the value of the “instance_size” field. When overloading is enabled, this is equivalent to

get paramSpecTypeInfo #instanceSize

setParamSpecTypeInfoInstanceSize :: MonadIO m => ParamSpecTypeInfo -> Word16 -> m ()

Set the value of the “instance_size” field. When overloading is enabled, this is equivalent to

set paramSpecTypeInfo [ #instanceSize := value ]

nPreallocs

Prior to GLib 2.10, it specified the number of pre-allocated (cached) instances to reserve memory for (0 indicates no caching). Since GLib 2.10, it is ignored, since instances are allocated with the [slice allocator][glib-Memory-Slices] now.

getParamSpecTypeInfoNPreallocs :: MonadIO m => ParamSpecTypeInfo -> m Word16

Get the value of the “n_preallocs” field. When overloading is enabled, this is equivalent to

get paramSpecTypeInfo #nPreallocs

setParamSpecTypeInfoNPreallocs :: MonadIO m => ParamSpecTypeInfo -> Word16 -> m ()

Set the value of the “n_preallocs” field. When overloading is enabled, this is equivalent to

set paramSpecTypeInfo [ #nPreallocs := value ]

valueSetDefault

No description available in the introspection data.

clearParamSpecTypeInfoValueSetDefault :: MonadIO m => ParamSpecTypeInfo -> m ()

Set the value of the “value_set_default” field to Nothing. When overloading is enabled, this is equivalent to

clear #valueSetDefault

getParamSpecTypeInfoValueSetDefault :: MonadIO m => ParamSpecTypeInfo -> m (Maybe ParamSpecTypeInfoValueSetDefaultFieldCallback)

Get the value of the “value_set_default” field. When overloading is enabled, this is equivalent to

get paramSpecTypeInfo #valueSetDefault

setParamSpecTypeInfoValueSetDefault :: MonadIO m => ParamSpecTypeInfo -> FunPtr C_ParamSpecTypeInfoValueSetDefaultFieldCallback -> m ()

Set the value of the “value_set_default” field. When overloading is enabled, this is equivalent to

set paramSpecTypeInfo [ #valueSetDefault := value ]

valueType

The GType of values conforming to this ParamSpec

getParamSpecTypeInfoValueType :: MonadIO m => ParamSpecTypeInfo -> m GType

Get the value of the “value_type” field. When overloading is enabled, this is equivalent to

get paramSpecTypeInfo #valueType

setParamSpecTypeInfoValueType :: MonadIO m => ParamSpecTypeInfo -> GType -> m ()

Set the value of the “value_type” field. When overloading is enabled, this is equivalent to

set paramSpecTypeInfo [ #valueType := value ]

valueValidate

No description available in the introspection data.

clearParamSpecTypeInfoValueValidate :: MonadIO m => ParamSpecTypeInfo -> m ()

Set the value of the “value_validate” field to Nothing. When overloading is enabled, this is equivalent to

clear #valueValidate

getParamSpecTypeInfoValueValidate :: MonadIO m => ParamSpecTypeInfo -> m (Maybe ParamSpecTypeInfoValueValidateFieldCallback)

Get the value of the “value_validate” field. When overloading is enabled, this is equivalent to

get paramSpecTypeInfo #valueValidate

setParamSpecTypeInfoValueValidate :: MonadIO m => ParamSpecTypeInfo -> FunPtr C_ParamSpecTypeInfoValueValidateFieldCallback -> m ()

Set the value of the “value_validate” field. When overloading is enabled, this is equivalent to

set paramSpecTypeInfo [ #valueValidate := value ]

valuesCmp

No description available in the introspection data.

clearParamSpecTypeInfoValuesCmp :: MonadIO m => ParamSpecTypeInfo -> m ()

Set the value of the “values_cmp” field to Nothing. When overloading is enabled, this is equivalent to

clear #valuesCmp

getParamSpecTypeInfoValuesCmp :: MonadIO m => ParamSpecTypeInfo -> m (Maybe ParamSpecTypeInfoValuesCmpFieldCallback)

Get the value of the “values_cmp” field. When overloading is enabled, this is equivalent to

get paramSpecTypeInfo #valuesCmp

setParamSpecTypeInfoValuesCmp :: MonadIO m => ParamSpecTypeInfo -> FunPtr C_ParamSpecTypeInfoValuesCmpFieldCallback -> m ()

Set the value of the “values_cmp” field. When overloading is enabled, this is equivalent to

set paramSpecTypeInfo [ #valuesCmp := value ]
