Member Function Documentation

static void Pango::CairoFontMap::add_interface ( GType gtype_implementer )

static

static Glib::RefPtr<FontMap> Pango::CairoFontMap::get_default ( )

static

Gets a default Pango::CairoFontMap to use with Cairo.

Note that the type of the returned object will depend on the particular font backend Cairo was compiled to use; You generally should only use the Pango::FontMap and Pango::CairoFontMap interfaces on the returned object.

The default Cairo fontmap can be changed by using set_default(). This can be used to change the Cairo font backend that the default fontmap uses for example.

Note that since Pango 1.32.6, the default fontmap is per-thread. Each thread gets its own default fontmap. In this way, PangoCairo can be used safely from multiple threads.

Since pangomm 1.10:

Returns: The default PangoCairo fontmap for the current thread. This object is owned by Pango and must not be freed.

Cairo::FontType Pango::CairoFontMap::get_font_type ( ) const

Gets the type of Cairo font backend that fontmap uses.

Since pangomm 1.18:

Returns: The #cairo_font_type_t cairo font backend type.

double Pango::CairoFontMap::get_resolution ( ) const

Gets the resolution for the fontmap.

See set_resolution()

Since pangomm 1.10:

Returns: The resolution in "dots per inch".

static GType Pango::CairoFontMap::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

PangoCairoFontMap* Pango::CairoFontMap::gobj ( )

inline

Provides access to the underlying C GObject.

const PangoCairoFontMap* Pango::CairoFontMap::gobj ( ) const

inline

Provides access to the underlying C GObject.

CairoFontMap& Pango::CairoFontMap::operator= ( CairoFontMap&& src )

noexcept

void Pango::CairoFontMap::set_default ( )

Sets a default Pango::CairoFontMap to use with Cairo.

This can be used to change the Cairo font backend that the default fontmap uses for example. The old default font map is unreffed and the new font map referenced.

Note that since Pango 1.32.6, the default fontmap is per-thread. This function only changes the default fontmap for the current thread. Default fontmaps of existing threads are not changed. Default fontmaps of any new threads will still be created using new().

A value of nullptr for fontmap will cause the current default font map to be released and a new default font map to be created on demand, using new().

Since pangomm 1.22:

void Pango::CairoFontMap::set_resolution ( double dpi )

Sets the resolution for the fontmap.

This is a scale factor between points specified in a Pango::FontDescription and Cairo units. The default value is 96, meaning that a 10 point font will be 13 units high. (10* 96. / 72. = 13.3).

Since pangomm 1.10:

Parameters

dpi	The resolution in "dots per inch". (Physical inches aren't actually involved; the terminology is conventional.).

Friends And Related Function Documentation

Glib::RefPtr< Pango::CairoFontMap > wrap	(	PangoCairoFontMap *	object,
		bool	take_copy = `false`
	)

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
