GI.Pango.Structs.AttrFontDesc
Description
The PangoAttrFontDesc structure is used to store an attribute that
sets all aspects of the font description at once.
Synopsis
- newtype AttrFontDesc = AttrFontDesc (ManagedPtr AttrFontDesc)
- newZeroAttrFontDesc :: MonadIO m => m AttrFontDesc
- attrFontDescNew :: (HasCallStack, MonadIO m) => FontDescription -> m Attribute
- getAttrFontDescAttr :: MonadIO m => AttrFontDesc -> m Attribute
- clearAttrFontDescDesc :: MonadIO m => AttrFontDesc -> m ()
- getAttrFontDescDesc :: MonadIO m => AttrFontDesc -> m (Maybe FontDescription)
- setAttrFontDescDesc :: MonadIO m => AttrFontDesc -> Ptr FontDescription -> m ()

Arguments

| -> m Attribute | Returns: the newly allocated
|
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 Source #
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 () Source #
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) Source #
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 () Source #
Set the value of the “desc” field.
When overloading is enabled, this is equivalent to
setattrFontDesc [ #desc:=value ]
