Method Summary

Modifier and Type	Method	Description
void	run(Pixbuf pixbuf, int x, int y, int width, int height)	Defines the type of the function that gets called every time a region of pixbuf is updated.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, int, int, int, int, MemorySegment) method.

Method Details

run

void run(Pixbuf pixbuf,
 int x,
 int y,
 int width,
 int height)

Defines the type of the function that gets called every time a region of pixbuf is updated.

GdkPixbufLoader uses a function of this type to emit the "area_updated" signal.

Parameters:

pixbuf - the GdkPixbuf that is currently being loaded.

x - the X origin of the updated area.

y - the Y origin of the updated area.

width - the width of the updated area.

height - the height of the updated area.

2.2

upcall

default void upcall(MemorySegment pixbuf,
 int x,
 int y,
 int width,
 int height,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(Pixbuf, int, int, int, int) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, int, int, int, int, MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
