Constructor Details

CairoNode

public CairoNode(PointerContainer pointer)

CairoNode

public CairoNode(@Nonnull
 Rect bounds)

Creates a `GskRenderNode` that will render a cairo surface
into the area given by @bounds.

You can draw to the cairo surface using [method@Gsk.CairoNode.get_draw_context].

Parameters:

bounds - the rectangle to render to

Method Details

getClassHandler

public static ClassHandler getClassHandler()

getDrawContext

public Context getDrawContext()

Creates a Cairo context for drawing using the surface associated
to the render node.

If no surface exists yet, a surface will be created optimized for
rendering to @renderer.

Returns:

a Cairo context used for drawing; use cairo_destroy() when done drawing

getSurface

public Surface getSurface()

Retrieves the Cairo surface used by the render node.

Returns:

a Cairo surface

getTypeID

public static long getTypeID()

getParentTypeID

public static long getParentTypeID()

getTypeSize

public static TypeSystem.TypeSize getTypeSize()

getParentTypeSize

public static TypeSystem.TypeSize getParentTypeSize()

getInstanceSize

public static int getInstanceSize()
