Description

A Fontset represents a set of Font to use when rendering text. It is the result of resolving a FontDescription against a particular Context. 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.

fontsetForeach Source #

Arguments

:: (HasCallStack, MonadIO m, IsFontset a)
=> a	`fontset`: a `Fontset`
-> FontsetForeachFunc	`func`: Callback function
-> m ()

Iterates through all the fonts in a fontset, calling func for each one. If func returns True, that stops the iteration.

Instances

((~) * signature (Word32 -> m Font), MonadIO m, IsFontset a) => MethodInfo * FontsetGetFontMethodInfo a signature Source #
Methods overloadedMethod :: MethodProxy FontsetGetFontMethodInfo a -> signature -> s #

fontsetGetFont Source #

Arguments

:: (HasCallStack, MonadIO m, IsFontset a)
=> a	`fontset`: a `Fontset`
-> Word32	`wc`: a Unicode character
-> m Font	Returns: a `Font`. The caller must call g_object_unref when finished with the font.

Returns the font in the fontset that contains the best glyph for the Unicode character wc.

Instances

((~) * signature (m FontMetrics), MonadIO m, IsFontset a) => MethodInfo * FontsetGetMetricsMethodInfo a signature Source #

fontsetGetMetrics Source #

Arguments

:: (HasCallStack, MonadIO m, IsFontset a)
=> a	`fontset`: a `Fontset`
-> m FontMetrics	Returns: a `FontMetrics` object. The caller must call `fontMetricsUnref` when finished using the object.

Get overall metric information for the fonts in the fontset.
