public class FontMap
extends PropertyHolder

A `PangoFontMap` represents the set of fonts available for a
particular rendering system.

This is a virtual object with implementations being specific to
particular rendering systems.

FontMap

public FontMap(PointerContainer pointer)

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

addFontFile

public boolean addFontFile(@Nonnull
 Str filename)
                    throws AllocationError

Loads a font file with one or more fonts into the `PangoFontMap`.

The added fonts will take precedence over preexisting
fonts with the same name.

Parameter:

filename - Path to the font file

Gibt zurück:

True if the font file is successfully loaded into the fontmap, false if an error occurred.

Löst aus:

AllocationError

addFontFile

public boolean addFontFile(String filename)
                    throws AllocationError

Loads a font file with one or more fonts into the `PangoFontMap`.

The added fonts will take precedence over preexisting
fonts with the same name.

Parameter:

filename - Path to the font file

Gibt zurück:

True if the font file is successfully loaded into the fontmap, false if an error occurred.

Löst aus:

AllocationError

changed

public void changed()

Forces a change in the context, which will cause any `PangoContext`
using this fontmap to change.

This function is only useful when implementing a new backend
for Pango, something applications won't do. Backends should
call this function if they have attached extra data to the
context and such data is changed.

createContext

public Context createContext()

Creates a `PangoContext` connected to @fontmap.

This is equivalent to [ctor@Pango.Context.new] followed by
[method@Pango.Context.set_font_map].

If you are using Pango as part of a higher-level system,
that system may have it's own way of create a `PangoContext`.
For instance, the GTK toolkit has, among others,
gtk_widget_get_pango_context(). Use those instead.

Gibt zurück:

the newly allocated `PangoContext`, which should be freed with g_object_unref().

getFamily

public FontFamily getFamily(@Nonnull
 Str name)

Gets a font family by name.

Parameter:

name - a family name

Gibt zurück:

the `PangoFontFamily`

getFamily

public FontFamily getFamily(String name)

Gets a font family by name.

Parameter:

name - a family name

Gibt zurück:

the `PangoFontFamily`

getSerial

public int getSerial()

Returns the current serial number of @fontmap.

The serial number is initialized to an small number larger than zero
when a new fontmap is created and is increased whenever the fontmap
is changed. It may wrap, but will never have the value 0. Since it can
wrap, never compare it with "less than", always use "not equals".

The fontmap can only be changed using backend-specific API, like changing
fontmap resolution.

This can be used to automatically detect changes to a `PangoFontMap`,
like in `PangoContext`.

Gibt zurück:

The current serial number of @fontmap.

loadFont

public Font loadFont(@Nonnull
 Context context,
 @Nonnull
 FontDescription desc)

Load the font in the fontmap that is the closest match for @desc.

Parameter:

context - the `PangoContext` the font will be used with

desc - a `PangoFontDescription` describing the font to load

Gibt zurück:

the newly allocated `PangoFont` loaded, or %NULL if no font matched.

loadFontset

public Fontset loadFontset(@Nonnull
 Context context,
 @Nonnull
 FontDescription desc,
 @Nonnull
 Language language)

Load a set of fonts in the fontmap that can be used to render
a font matching @desc.

Parameter:

context - the `PangoContext` the font will be used with

desc - a `PangoFontDescription` describing the font to load

language - a `PangoLanguage` the fonts will be used for

Gibt zurück:

the newly allocated `PangoFontset` loaded, or %NULL if no font matched.

reloadFont

public Font reloadFont(@Nonnull
 Font font,
 double scale,
 @Nullable
 Context context,
 @Nullable
 Str variations)

Returns a new font that is like @font, except that its size
is multiplied by @scale, its backend-dependent configuration
(e.g. cairo font options) is replaced by the one in @context,
and its variations are replaced by @variations.

Parameter:

font - a font in @fontmap

scale - the scale factor to apply

context - a `PangoContext`

variations - font variations to use

Gibt zurück:

the modified font

reloadFont

public Font reloadFont(@Nonnull
 Font font,
 double scale,
 @Nullable
 Context context,
 String variations)

Returns a new font that is like @font, except that its size
is multiplied by @scale, its backend-dependent configuration
(e.g. cairo font options) is replaced by the one in @context,
and its variations are replaced by @variations.

Parameter:

font - a font in @fontmap

scale - the scale factor to apply

context - a `PangoContext`

variations - font variations to use

Gibt zurück:

the modified font

asListModel

ListModel

getTypeID

getParentTypeID

getTypeSize

public static TypeSystem.TypeSize getTypeSize()
