PointerInterface

public class PaintableInterface
extends Record

The list of functions that can be implemented for the `GdkPaintable`
interface.

Note that apart from the [vfunc@Gdk.Paintable.snapshot] function,
no virtual function of this interface is mandatory to implement, though it
is a good idea to implement [vfunc@Gdk.Paintable.get_current_image]
for non-static paintables and [vfunc@Gdk.Paintable.get_flags] if the
image is not dynamic as the default implementation returns no flags and
that will make the implementation likely quite slow.

G_IFACE

public static final String G_IFACE

Private field: direct-type

SNAPSHOT

public static final String SNAPSHOT

Snapshot the paintable. The given @width and @height are
guaranteed to be larger than 0.0. The resulting snapshot must modify
only the area in the rectangle from (0,0) to (width, height).
This is the only function that must be implemented for this interface.

GET_CURRENT_IMAGE

public static final String GET_CURRENT_IMAGE

return a `GdkPaintable` that does not change over
time. This means the `GDK_PAINTABLE_STATIC_SIZE` and
`GDK_PAINTABLE_STATIC_CONTENTS` flag are set.

GET_INTRINSIC_WIDTH

public static final String GET_INTRINSIC_WIDTH

The preferred width for this object to be
snapshot at or 0 if none. This is purely a hint. The object must still
be able to render at any size.

GET_INTRINSIC_ASPECT_RATIO

public static final String GET_INTRINSIC_ASPECT_RATIO

The preferred aspect ratio for this object
or 0 if none. If both [vfunc@Gdk.Paintable.get_intrinsic_width]
and [vfunc@Gdk.Paintable.get_intrinsic_height] return non-zero
values, this function should return the aspect ratio computed from those.
