Method Details

run

void run(Pixbuf pixbuf,
 PixbufAnimation anim)

Defines the type of the function that gets called once the initial setup of pixbuf is done.

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

Parameters:

pixbuf - the GdkPixbuf that is currently being loaded.

anim - if an animation is being loaded, the GdkPixbufAnimation, else null.

2.2

upcall

default void upcall(MemorySegment pixbuf,
 MemorySegment anim,
 MemorySegment userData)

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

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated
