@NativeType:struct JAWT_DrawingSurface
Imports
javax.annotation.*, java.nio.*, org.lwjgl.system.*

Structure for containing the underlying drawing information of a component.

All operations on a JAWT_DrawingSurface MUST be performed from the same thread as the call to GetDrawingSurface.

JAWTDrawingSurfaceback to summary
public JAWTDrawingSurface(ByteBuffer container)

Creates a JAWTDrawingSurface instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

The created instance holds a strong reference to the container object.

Method Detail

createback to summary
protected JAWTDrawingSurface create(long address, ByteBuffer container)

Implements abstract org.lwjgl.system.Struct.create.

Doc from org.lwjgl.system.Struct.create.

Similar to the constructor, but returns the exact type of the Struct subclass.

Effectively, every Struct instance is a factory for more instances of the same type. This is used by StructBuffer.

Parameters
address:long

the struct memory address

container:ByteBuffer

an optional container buffer, to be referenced strongly by the struct instance.

Create a JAWTDrawingSurface.Buffer instance at the specified memory.

Parameters
address:long

Constructor Detail

Bufferback to summary
public Buffer(ByteBuffer container)

Creates a new JAWTDrawingSurface.Buffer instance backed by the specified container.

Changes to the container's content will be visible to the struct buffer instance and vice versa. The two buffers' position, limit, and mark values will be independent. The new buffer's position will be zero, its capacity and its limit will be the number of bytes remaining in this buffer divided by JAWTDrawingSurface#SIZEOF, and its mark will be undefined.

The created buffer instance holds a strong reference to the container object.
