Record Class SDL_PenProximityEvent

java.lang.Object
java.lang.Record
club.doki7.sdl3.datatype.SDL_PenProximityEvent
All Implemented Interfaces:
IPointer, ISDL_PenProximityEvent

@ValueBasedCandidate @UnsafeConstructor public record SDL_PenProximityEvent(@NotNull MemorySegment segment) extends Record implements ISDL_PenProximityEvent

Pressure-sensitive pen proximity event structure (event.pmotion.*)

When a pen becomes visible to the system (it is close enough to a tablet, etc), SDL will send an SDL_EVENT_PEN_PROXIMITY_IN event with the new pen's ID. This ID is valid until the pen leaves proximity again (has been removed from the tablet's area, the tablet has been unplugged, etc). If the same pen reenters proximity again, it will be given a new ID.

Note that "proximity" means "close enough for the tablet to know the tool is there." The pen touching and lifting off from the tablet while not leaving the area are handled by SDL_EVENT_PEN_DOWN and SDL_EVENT_PEN_UP.

Since: This struct is available since SDL 3.2.0.

Structure

typedef struct SDL_PenProximityEvent {
    SDL_EventType type;
    Uint32 reserved;
    Uint64 timestamp;
    SDL_WindowID windowID;
    SDL_PenID which;
} SDL_PenProximityEvent;

Contracts

The property segment() should always be not-null (segment != NULL && !segment.equals(MemorySegment.NULL)), and properly aligned to LAYOUT.byteAlignment() bytes. To represent null pointer, you may use a Java null instead. See the documentation of IPointer.segment() for more details.

The constructor of this class is marked as UnsafeConstructor, because it does not perform any runtime check. The constructor can be useful for automatic code generators.
