@Generated("org.javagi.JavaGI")
public abstract class Fontset
extends GObject

A PangoFontset represents a set of PangoFont to use when rendering text.

A PangoFontset is the result of resolving a PangoFontDescription against a particular PangoContext. It has operations for finding the component font for a particular Unicode character, and for finding a composite set of metrics for the entire fontset.

Constructor Details

Fontset

public Fontset(MemorySegment address)

Create a Fontset instance for the provided memory address.

Parameters:

address - the memory address of the native object

Fontset

public Fontset()

Create a new Fontset.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the Fontset class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected Fontset asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class GObject

Returns:

the instance as if it were its parent type

foreach

public void foreach(@Nullable FontsetForeachFunc func)

Iterates through all the fonts in a fontset, calling func for each one.

If func returns true, that stops the iteration.

Parameters:

func - Callback function

Since:

1.4

getFont

public Font getFont(int wc)

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

Parameters:

wc - a Unicode character

Returns:

a PangoFont

getMetrics

public FontMetrics getMetrics()

Get overall metric information for the fonts in the fontset.

Returns:

a PangoFontMetrics object

getLanguage

protected Language getLanguage()

a function to get the language of the fontset.
