Direct Known Subclasses:

CairoContext.CairoContext$Impl

@Generated("org.javagi.JavaGI")
public abstract class CairoContext
extends DrawContext

Represents the platform-specific draw context.

GdkCairoContexts are created for a surface using Surface.createCairoContext(), and the context can then be used to draw on that surface.

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	CairoContext.Builder<B extends CairoContext.Builder<B>>	Inner class implementing a builder pattern to construct a GObject with properties.
static class	CairoContext.CairoContext$Impl	The CairoContext$Impl type represents a native instance of the abstract CairoContext class.

Constructor Summary

Constructors

Constructor	Description
CairoContext()	Create a new CairoContext.
CairoContext(MemorySegment address)	Create a CairoContext instance for the provided memory address.

Method Summary

Modifier and Type	Method	Description
protected CairoContext	asParent()	Return this instance as if it were its parent type.
@Nullable org.freedesktop.cairo.Context	cairoCreate()	Deprecated. Drawing content with Cairo should be done via Cairo rendernodes, not by using renderers.
static MemoryLayout	getMemoryLayout()	The memory layout of the native struct.
static @Nullable Type	getType()	Get the GType of the CairoContext class.

Constructor Details

CairoContext

public CairoContext(MemorySegment address)

Create a CairoContext instance for the provided memory address.

Parameters:

address - the memory address of the native object

CairoContext

public CairoContext()

Create a new CairoContext.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the CairoContext class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected CairoContext 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 DrawContext

Returns:

the instance as if it were its parent type

cairoCreate

@Deprecated
public @Nullable org.freedesktop.cairo.Context cairoCreate()

Deprecated.

Drawing content with Cairo should be done via Cairo rendernodes, not by using renderers.

Retrieves a Cairo context to be used to draw on the GdkSurface of context.

A call to DrawContext.beginFrame(Region) with this context must have been done or this function will return null.

The returned context is guaranteed to be valid until DrawContext.endFrame() is called.

Returns:

a Cairo context to draw on `GdkSurface
