Member documentation

• <union>
  • hwnd – the native window handle
  • hbitmap – the DDB handle
  • pbits – the DIB handle
• hdc – the device context handle. This HDC should always be used instead of the HDC returned from BeginPaint() or any calls to User32.GetDC(long).
• hpalette – the palette handle

Constructor Detail

JAWTWin32DrawingSurfaceInfo

public JAWTWin32DrawingSurfaceInfo(java.nio.ByteBuffer container)

Creates a JAWTWin32DrawingSurfaceInfo 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

sizeof

public int sizeof()

Specified by:

sizeof in class org.lwjgl.system.Struct

hwnd

public long hwnd()

Returns the value of the hwnd field.

hbitmap

public long hbitmap()

Returns the value of the hbitmap field.

pbits

public java.nio.ByteBuffer pbits(int capacity)

Returns a ByteBuffer view of the data pointed to by the pbits field.

Parameters:

capacity - the number of elements in the returned buffer

hdc

public long hdc()

Returns the value of the hdc field.

hpalette

public long hpalette()

Returns the value of the hpalette field.

create

public static JAWTWin32DrawingSurfaceInfo create(long address)

Returns a new JAWTWin32DrawingSurfaceInfo instance for the specified memory address.

createSafe

@Nullable
public static JAWTWin32DrawingSurfaceInfo createSafe(long address)

Like create, but returns null if address is NULL.

create

public static JAWTWin32DrawingSurfaceInfo.Buffer create(long address,
                                                        int capacity)

Create a JAWTWin32DrawingSurfaceInfo.Buffer instance at the specified memory.

Parameters:

address - the memory address

capacity - the buffer capacity

createSafe

@Nullable
public static JAWTWin32DrawingSurfaceInfo.Buffer createSafe(long address,
                                                            int capacity)

Like create, but returns null if address is NULL.

nhwnd

public static long nhwnd(long struct)

Unsafe version of hwnd().

nhbitmap

public static long nhbitmap(long struct)

Unsafe version of hbitmap().

npbits

public static java.nio.ByteBuffer npbits(long struct,
                                         int capacity)

Unsafe version of pbits.

nhdc

public static long nhdc(long struct)

Unsafe version of hdc().

nhpalette

public static long nhpalette(long struct)

Unsafe version of hpalette().
