Constructor Details

FontFace

public FontFace(MemorySegment address)

Create a FontFace proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the FontFace class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected FontFace asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class GObject

describe

public FontDescription describe()

Returns a font description that matches the face.

The resulting font description will have the family, style, variant, weight and stretch of the face, but its size field will be unset.

Returns:

a newly-created PangoFontDescription structure holding the description of the face. Use FontDescription.free() to free the result.

getFaceName

public String getFaceName()

Gets a name representing the style of this face.

Note that a font family may contain multiple faces with the same name (e.g. a variable and a non-variable face for the same style).

Returns:

the face name for the face. This string is owned by the face object and must not be modified or freed.

getFamily

public FontFamily getFamily()

Gets the PangoFontFamily that this FontFace belongs to.

Returns:

the PangoFontFamily

isSynthesized

public boolean isSynthesized()

Returns whether a PangoFontFace is synthesized.

This will be the case if the underlying font rendering engine creates this face from another face, by shearing, emboldening, lightening or modifying it in some other way.

Returns:

whether this FontFace is synthesized

listSizes

public void listSizes(@Nullable
 @Nullable Out<int[]> sizes)

List the available sizes for a font.

This is only applicable to bitmap fonts. For scalable fonts, stores null at the location pointed to by sizes and 0 at the location pointed to by nSizes. The sizes returned are in Pango units and are sorted in ascending order.

Parameters:

sizes - location to store a pointer to an array of int. This array should be freed with g_free().

builder

public static FontFace.Builder<? extends FontFace.Builder> builder()

A FontFace.Builder object constructs a FontFace with the specified properties. Use the various set...() methods to set properties, and finish construction with FontFace.Builder.build().
