Method Details

run

void run(GObject object,
 int propertyId,
 Value value,
 ParamSpec pspec)

The type of the getProperty function of GObjectClass.

Parameters:

object - a GObject

propertyId - the numeric id under which the property was registered with g_object_class_install_property().

value - a GValue to return the property value in

pspec - the GParamSpec describing the property

upcall

default void upcall(MemorySegment object,
 int propertyId,
 MemorySegment value,
 MemorySegment pspec)

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

toCallback

default MemorySegment toCallback(Arena arena)

Parameters:

arena - the arena in which the function pointer is allocated
