Constructor Details

AttrShape

public AttrShape(MemorySegment address)

Create a AttrShape proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

AttrShape

public AttrShape(Arena arena)

Allocate a new AttrShape.

Parameters:

arena - to control the memory allocation scope

AttrShape

public AttrShape()

Allocate a new AttrShape. The memory is allocated with Arena.ofAuto().

AttrShape

public AttrShape(Attribute attr,
 Rectangle inkRect,
 Rectangle logicalRect,
 MemorySegment data,
 AttrDataCopyFunc copyFunc,
 DestroyNotify destroyFunc,
 Arena arena)

Allocate a new AttrShape with the fields set to the provided values.

Parameters:

attr - value for the field attr

inkRect - value for the field inkRect

logicalRect - value for the field logicalRect

data - value for the field data

copyFunc - value for the field copyFunc

destroyFunc - value for the field destroyFunc

arena - to control the memory allocation scope

AttrShape

public AttrShape(Attribute attr,
 Rectangle inkRect,
 Rectangle logicalRect,
 MemorySegment data,
 AttrDataCopyFunc copyFunc,
 DestroyNotify destroyFunc)

Allocate a new AttrShape with the fields set to the provided values. The memory is allocated with Arena.ofAuto().

Parameters:

attr - value for the field attr

inkRect - value for the field inkRect

logicalRect - value for the field logicalRect

data - value for the field data

copyFunc - value for the field copyFunc

destroyFunc - value for the field destroyFunc

Method Details

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

readAttr

public @Nullable Attribute readAttr()

Read the value of the field attr.

Returns:

The value of the field attr

writeAttr

public void writeAttr(@Nullable Attribute attr)

Write a value in the field attr.

Parameters:

attr - The new value for the field attr

readInkRect

public @Nullable Rectangle readInkRect()

Read the value of the field ink_rect.

Returns:

The value of the field ink_rect

writeInkRect

public void writeInkRect(@Nullable Rectangle inkRect)

Write a value in the field ink_rect.

Parameters:

inkRect - The new value for the field ink_rect

readLogicalRect

public @Nullable Rectangle readLogicalRect()

Read the value of the field logical_rect.

Returns:

The value of the field logical_rect

writeLogicalRect

public void writeLogicalRect(@Nullable Rectangle logicalRect)

Write a value in the field logical_rect.

Parameters:

logicalRect - The new value for the field logical_rect

readData

public MemorySegment readData()

Read the value of the field data.

Returns:

The value of the field data

writeData

public void writeData(MemorySegment data)

Write a value in the field data.

Parameters:

data - The new value for the field data

readCopyFunc

public @Nullable AttrDataCopyFunc readCopyFunc()

Read the value of the field copy_func.

Returns:

The value of the field copy_func

writeCopyFunc

public void writeCopyFunc(@Nullable AttrDataCopyFunc copyFunc,
 Arena _arena)

Write a value in the field copy_func.

Parameters:

copyFunc - The new value for the field copy_func

_arena - to control the memory allocation scope

readDestroyFunc

public @Nullable DestroyNotify readDestroyFunc()

Read the value of the field destroy_func.

Returns:

The value of the field destroy_func

writeDestroyFunc

public void writeDestroyFunc(@Nullable DestroyNotify destroyFunc,
 Arena _arena)

Write a value in the field destroy_func.

Parameters:

destroyFunc - The new value for the field destroy_func

_arena - to control the memory allocation scope

new_

public static Attribute new_(Rectangle inkRect,
 Rectangle logicalRect)

Create a new shape attribute.

A shape is used to impose a particular ink and logical rectangle on the result of shaping a particular glyph. This might be used, for instance, for embedding a picture or a widget inside a PangoLayout.

Parameters:

inkRect - ink rectangle to assign to each character

logicalRect - logical rectangle to assign to each character

Returns:

the newly allocated PangoAttribute, which should be freed with Attribute.destroy()

newWithData

public static Attribute newWithData(Rectangle inkRect,
 Rectangle logicalRect,
 @Nullable MemorySegment data,
 @Nullable AttrDataCopyFunc copyFunc)

Creates a new shape attribute.

Like new_(org.gnome.pango.Rectangle, org.gnome.pango.Rectangle), but a user data pointer is also provided; this pointer can be accessed when later rendering the glyph.

Parameters:

inkRect - ink rectangle to assign to each character

logicalRect - logical rectangle to assign to each character

data - user data pointer

copyFunc - function to copy data when the attribute is copied. If null, data is simply copied as a pointer

Returns:

the newly allocated PangoAttribute, which should be freed with Attribute.destroy()
