Methods

Methods

Overloaded methods

new

attrFontDescNew

Arguments

:: (HasCallStack, MonadIO m)

=> FontDescription

desc: the font description

-> m Attribute

Returns: the newly allocated Attribute, which should be freed with attributeDestroy.

Create a new font description attribute. This attribute allows setting family, style, weight, variant, stretch, and size simultaneously.

Properties

attr

the common portion of the attribute

getAttrFontDescAttr :: MonadIO m => AttrFontDesc -> m Attribute

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

get attrFontDesc #attr

desc

the font description which is the value of this attribute

clearAttrFontDescDesc :: MonadIO m => AttrFontDesc -> m ()

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

clear #desc

getAttrFontDescDesc :: MonadIO m => AttrFontDesc -> m (Maybe FontDescription)

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

get attrFontDesc #desc

setAttrFontDescDesc :: MonadIO m => AttrFontDesc -> Ptr FontDescription -> m ()

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

set attrFontDesc [ #desc := value ]
