Method Details

run

void run(@Nullable TextIter iter,
 @Nullable Rectangle area,
 int button,
 Set<ModifierType> state,
 int nPresses)

The signal is emitted when the renderer is activated.

upcall

default void upcall(MemorySegment sourceGutterRenderer,
 MemorySegment iter,
 MemorySegment area,
 int button,
 int state,
 int nPresses)

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

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated
