Member Function Documentation
void Pango::Fontset::foreach | ( | const ForeachSlot& | slot | ) |
Iterates through all the fonts in a fontset, calling slot for each one.
If slot returns true, that stops the iteration.
- Since
- -1.4
- Parameters
-
slot Callback function
Glib::RefPtr<Font> Pango::Fontset::get_font | ( | guint | wc | ) | const |
Returns the font in the fontset that contains the best glyph for the Unicode character wc.
- Parameters
-
wc A Unicode character.
- Returns
- A Pango::Font. The caller must call g_object_unref when finished with the font.
FontMetrics Pango::Fontset::get_metrics | ( | ) | const |
Get overall metric information for the fonts in the fontset.
- Returns
- A Pango::FontMetrics object. The caller must call Pango::FontMetrics::unref() when finished using the object.

PangoFontset* Pango::Fontset::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
