GI.Pango.Objects.Fontset
Description
A PangoFontset represents a set of PangoFont to use when rendering text.
A PangoFontset is the result of resolving a PangoFontDescription
against a particular PangoContext. It has operations for finding the
component font for a particular Unicode character, and for finding a
composite set of metrics for the entire fontset.
Synopsis
- newtype Fontset = Fontset (ManagedPtr Fontset)
- class (GObject o, IsDescendantOf Fontset o) => IsFontset o
- toFontset :: (MonadIO m, IsFontset o) => o -> m Fontset
- fontsetForeach :: (HasCallStack, MonadIO m, IsFontset a) => a -> FontsetForeachFunc -> m ()
- fontsetGetFont :: (HasCallStack, MonadIO m, IsFontset a) => a -> Word32 -> m Font
- fontsetGetMetrics :: (HasCallStack, MonadIO m, IsFontset a) => a -> m FontMetrics

Setters
foreach
Arguments
| :: (HasCallStack, MonadIO m, IsFontset a) | |
| => a |
|
| -> FontsetForeachFunc |
|
| -> m () |
Iterates through all the fonts in a fontset, calling func for
each one.
If func returns True, that stops the iteration.
Since: 1.4
getFont
Arguments
| :: (HasCallStack, MonadIO m, IsFontset a) | |
| => a |
|
| -> Word32 |
|
| -> m Font | Returns: a |
Returns the font in the fontset that contains the best glyph for a Unicode character.
getMetrics
Arguments
| :: (HasCallStack, MonadIO m, IsFontset a) | |
| => a |
|
| -> m FontMetrics | Returns: a |
Get overall metric information for the fonts in the fontset.
