GI.Pango.Structs.Attribute
Description
The PangoAttribute
structure represents the common portions of all
attributes.
Particular types of attributes include this structure as their initial
portion. The common portion of the attribute holds the range to which
the value in the type-specific part of the attribute applies and should
be initialized using [methodpango
.Attribute.init]. By default, an attribute
will have an all-inclusive range of [0,G_MAXUINT
].
Synopsis
- newtype Attribute = Attribute (ManagedPtr Attribute)
- attributeCopy :: (HasCallStack, MonadIO m) => Attribute -> m Attribute
- attributeDestroy :: (HasCallStack, MonadIO m) => Attribute -> m ()
- attributeEqual :: (HasCallStack, MonadIO m) => Attribute -> Attribute -> m Bool
- attributeInit :: (HasCallStack, MonadIO m) => Attribute -> AttrClass -> m ()
- getAttributeEndIndex :: MonadIO m => Attribute -> m Word32
- setAttributeEndIndex :: MonadIO m => Attribute -> Word32 -> m ()
- clearAttributeKlass :: MonadIO m => Attribute -> m ()
- getAttributeKlass :: MonadIO m => Attribute -> m (Maybe AttrClass)
- setAttributeKlass :: MonadIO m => Attribute -> Ptr AttrClass -> m ()
- getAttributeStartIndex :: MonadIO m => Attribute -> m Word32
- setAttributeStartIndex :: MonadIO m => Attribute -> Word32 -> m ()

Methods
Click to display all available methods, including inherited ones
copy
Arguments
:: (HasCallStack, MonadIO m) | |
=> Attribute |
|
-> m Attribute | Returns: the newly allocated
|
Make a copy of an attribute.
destroy
Arguments
:: (HasCallStack, MonadIO m) | |
=> Attribute |
|
-> m () |
Destroy a PangoAttribute
and free all associated memory.
equal
Arguments
:: (HasCallStack, MonadIO m) | |
=> Attribute |
|
-> Attribute |
|
-> m Bool | Returns: |
Compare two attributes for equality.
This compares only the actual value of the two attributes and not the ranges that the attributes apply to.
init
Arguments
:: (HasCallStack, MonadIO m) | |
=> Attribute |
|
-> AttrClass |
|
-> m () |
Initializes attr
's klass to klass
, it's start_index to
ATTR_INDEX_FROM_TEXT_BEGINNING
and end_index to
ATTR_INDEX_TO_TEXT_END
such that the attribute applies
to the entire text by default.
Since: 1.20
Properties
endIndex
end index of the range (in bytes). The character at this index is not included in the range.
getAttributeEndIndex :: MonadIO m => Attribute -> m Word32 Source #
Get the value of the “end_index
” field.
When overloading is enabled, this is equivalent to
get
attribute #endIndex
setAttributeEndIndex :: MonadIO m => Attribute -> Word32 -> m () Source #
Set the value of the “end_index
” field.
When overloading is enabled, this is equivalent to
set
attribute [ #endIndex:=
value ]
klass
the class structure holding information about the type of the attribute
clearAttributeKlass :: MonadIO m => Attribute -> m () Source #
Set the value of the “klass
” field to Nothing
.
When overloading is enabled, this is equivalent to
clear
#klass
getAttributeKlass :: MonadIO m => Attribute -> m (Maybe AttrClass) Source #
Get the value of the “klass
” field.
When overloading is enabled, this is equivalent to
get
attribute #klass
setAttributeKlass :: MonadIO m => Attribute -> Ptr AttrClass -> m () Source #
Set the value of the “klass
” field.
When overloading is enabled, this is equivalent to
set
attribute [ #klass:=
value ]
startIndex
the start index of the range (in bytes).
getAttributeStartIndex :: MonadIO m => Attribute -> m Word32 Source #
Get the value of the “start_index
” field.
When overloading is enabled, this is equivalent to
get
attribute #startIndex
setAttributeStartIndex :: MonadIO m => Attribute -> Word32 -> m () Source #
Set the value of the “start_index
” field.
When overloading is enabled, this is equivalent to
set
attribute [ #startIndex:=
value ]
