Trait containing all Fontset methods.

Implementors

FontsetSimple, Fontset

Required methods

fn foreach<P: FnMut(&Fontset, &Font) -> bool>(&self, func: P)

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

func

Callback function

fn font(&self, wc: u32) -> Option<Font>

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

wc

a Unicode character

Returns

a Font. The caller must call g_object_unref when finished with the font.

fn metrics(&self) -> Option<FontMetrics>

Get overall metric information for the fonts in the fontset.

Returns

a FontMetrics object. The caller must call pango_font_metrics_unref() when finished using the object.
