Description
The AttrString structure is used to represent attributes with
a string value.
Synopsis
- newtype AttrString = AttrString (ManagedPtr AttrString)
- newZeroAttrString :: MonadIO m => m AttrString
- noAttrString :: Maybe AttrString
- getAttrStringAttr :: MonadIO m => AttrString -> m Attribute
- clearAttrStringValue :: MonadIO m => AttrString -> m ()
- getAttrStringValue :: MonadIO m => AttrString -> m (Maybe Text)
- setAttrStringValue :: MonadIO m => AttrString -> CString -> m ()
Exported types
newtype AttrString Source #
Memory-managed wrapper type.
Constructors

Defined in GI.Pango.Structs.AttrString Methods wrappedPtrCalloc :: IO (Ptr AttrString) # wrappedPtrCopy :: AttrString -> IO AttrString # wrappedPtrFree :: Maybe (FunPtr (Ptr AttrString -> IO ())) # | |
| tag ~ AttrSet => Constructible AttrString tag Source # | |
Defined in GI.Pango.Structs.AttrString Methods new :: MonadIO m => (ManagedPtr AttrString -> AttrString) -> [AttrOp AttrString tag] -> m AttrString # | |
newZeroAttrString :: MonadIO m => m AttrString Source #
Construct a AttrString struct initialized to zero.
noAttrString :: Maybe AttrString Source #
A convenience alias for Nothing :: Maybe AttrString.
Properties
attr
the common portion of the attribute
getAttrStringAttr :: MonadIO m => AttrString -> m Attribute Source #
Get the value of the “attr” field.
When overloading is enabled, this is equivalent to
get attrString #attr
value
the string which is the value of the attribute
clearAttrStringValue :: MonadIO m => AttrString -> m () Source #
Set the value of the “value” field to Nothing.
When overloading is enabled, this is equivalent to
clear #value
getAttrStringValue :: MonadIO m => AttrString -> m (Maybe Text) Source #
Get the value of the “value” field.
When overloading is enabled, this is equivalent to
get attrString #value
setAttrStringValue :: MonadIO m => AttrString -> CString -> m () Source #
Set the value of the “value” field.
When overloading is enabled, this is equivalent to
setattrString [ #value:=value ]
