JavaScript port: desktop scrollbars for mouse-driven browsers by shai-almog · Pull Request #6073 · codenameone/CodenameOne

shai-almog · 2026-10-22T00:54:22Z

In a web build, scrollbars behaved like touch scrolling even under a desktop theme: dragging the thumb scrolled the content the opposite way (it was a swipe), and clicking the gutter did nothing.

Cause: the core's interactive (desktop) scrollbar is enabled by the interactiveScrollBool theme constant, which only the JavaSE port injects. HTML5Implementation never did, so the browser always used touch semantics.

Changes

HTML5Implementation.installNativeTheme sets @interactiveScrollBool when (any-pointer: fine) matches, unless the theme already declares it. Any fine pointer, not only the primary one, so a touch laptop gets a draggable scrollbar; the scrollbar only claims presses that land on it, so finger swipes over content still scroll.
New theme constant interactiveScrollTrackJumpBool (default off, LookAndFeel.isInteractiveScrollTrackJump()): a track click centers the thumb on the click and keeps it grabbed for dragging, instead of paging one viewport.
InteractiveScrollbarTest.trackClickJumpsToPositionWhenEnabled.

Verified locally: InteractiveScrollbarTest 10/10, core-unittests SpotBugs 0 findings, JS port classes compile. Not exercised in a real browser.

🤖 Generated with Claude Code

The JS port never injected the interactiveScrollBool theme constant the JavaSE desktop port injects, so in a browser a press on the scrollbar was handled as a press on the content: dragging the thumb became a touch swipe and scrolled the opposite way, and clicking the track did nothing. The port now sets the constant when the browser has any fine pointer, unless the theme declares it itself. The core also gains an interactiveScrollTrackJumpBool theme constant: a track click centers the thumb on the click and keeps it grabbed, instead of paging.

Compared 193 screenshots: 193 matched.
Native Windows port (x64 / Intel-AMD): full hellocodenameone screenshot suite rendered offscreen with Direct2D/DirectWrite, plus the real benchmarks (base64 native/CN1/SIMD, image createMask/applyMask/modifyAlpha/PNG/JPEG, SSE2 SIMD kernels). Compared against the in-repo baseline in scripts/windows/screenshots.

Detailed Performance Metrics

Metric	Duration
SIMD kernel backend	SSE2 (x64) / NEON (arm64) native kernels
SIMD int-add (64K x300)	java 28ms / native 3ms = 9.3x speedup
SIMD float-mul (64K x300)	java 28ms / native 2ms = 14.0x speedup
SIMD kernel correctness	PASS (native result == scalar reference)
Base64 native bridge	unavailable (CN1 + SIMD + image benchmarks only)
Base64 payload size	8192 bytes
Base64 benchmark iterations	6000
Base64 SIMD byte path	gated to scalar (CPU autovectorizes scalar; explicit SIMD not beneficial here)

…ly pointer #6073 gives any browser with a fine pointer desktop scrollbars. Headless Chromium reports a mouse, so every scrollable screen in the phone-sized suite gained an always-visible gutter and 48 goldens stopped matching. Answer only (any-pointer: fine) as a touch device would; the coarse query isPrimaryPointerMouse() reads keeps Chromium's answer. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

) * Security: P-256 key generation, ECDH key agreement and HKDF on every port KeyGenerator.ec, KeyAgreement.ecdh and Hkdf (RFC 5869, pure Java, shared with the backend). JavaSE and Android use the JCA; iOS Security.framework, Linux OpenSSL EVP, Windows BCrypt and the browser Web Crypto. EcP256Codec keeps the DER in Java so every port hands out byte-identical SPKI/PKCS#8. Fixes ECDSA on iOS (cn1_crypto_sign loaded every key as RSA) and in the browser (the bridge refused EC signatures outright). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: messaging sample skeleton, shared contracts and backend Reactor, shared DTO/RestClient contracts, and the Codename One backend: accounts, devices and prekeys, conversations and groups, the per-device envelope queue, media blobs, live frames and push, privacy and moderation, call signalling with TURN credentials, Telegram and WhatsApp Cloud bridges, demo seed and bot. Client modules follow. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: client messaging - chats, groups, media, privacy, admin Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * WebRTC: com.codename1.webrtc with Android, iOS, browser and simulator ports Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: voice and video calls over WebRTC with system call integration Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: browser e2e as a linked device, admin console from the overflow menu Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: Initializr template, CI workflow and developer guide chapters Adds the PARLEY full-stack template, parley.yml (backend, simulator and browser e2e, template, Android and iOS builds), the user's and implementor's guide chapters, a WebRTC chapter and the ECDH/HKDF security section. A full-stack template generated for Java 17 now raises the root pom's compiler level too, which the server and the shared module inherit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Initializr: track the parley template archives Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: review fixes, safe-area layout, browser WebRTC bridge, guide screenshots Server: a stale device copy is detected by device and owner, direct chats are unique in the database, each person holds one call line, and the offer and early ICE wait for a callee that was not connected. Client: call failures only end the call they belong to, a repeated offer is ignored, the media cache is bounded and cleared on wipe, acks survive a restart, expiry runs from the summary, and a registration answer is only applied to the identity it was sent for. Ports: iOS queues ICE until the remote description is set and detaches remote tracks on close; Android enters communication mode for a call; the browser WebRTC runs in the host bridge; the JavaSE desktop app has no simulator WebRTC. UI: the chat composer carries the bottom safe area, the title is centred on its avatar and buttons, and segmented choices always show the chosen option. Guide images were recaptured. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * WebRTC: runnable javadoc examples; call and server snippets opt out of Try it A call needs a second device the Playground does not have, and the Parley security rules are server code. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: no regex split in the compiled server, guide prose, a sturdier admin menu pick Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: atomic prekey claim, busy on a lost call line, call-line cleanup, reject unauthenticated plaintext, WebRTC remote track lifetime and browser audio; Initializr Parley README and selector; snippets; JS size baseline Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: crash-safe vault writes, prekeys spent after authentication, envelopes announced after commit, raced direct chats and bridge links, webhook dedupe, unsent messages resent, rotation without prekey growth; P-256-only ECDH; WebRTC audio source and iOS audio session cleanup; Android Ant build excludes webrtc Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: entity column types match the migrations on PostgreSQL and MySQL; VoIP token unregistered on sign-out; Android call pushes reconnect and the server replays rings to a connecting device; signalling devices must be the signaller's; conversation frames after commit; reaped calls notify both peers Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: V0 migration makes MySQL/MariaDB text keys case sensitive and NO PAD (no-op on SQLite and PostgreSQL) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: messages bound to their conversation; calls end on sign-out; signals of one call serialized and a late second answer refused; busy only on a real line conflict; bridges relay after commit; message sends rate limited; a direct chat goes with a closed account; chat screens release the recorder, its clock and the store listener Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: vault promotes a recovered side file before overwriting it; blocked callers never take the callee's line; call frames and ring cancels sent after commit; uploads capped by bytes per day; one-time prekeys rate limited per target device; attachments bounded before buffering; muted bridged chats stop pushing; expired unread messages leave the badge; TeaVM WebRTC fallback plays remote audio; browser ECDSA signs on the key's curve; Call Management keeps its default anchor Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Starter launchers: macOS job timeout fits the thirty-odd Initializr downloads it now runs Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: received plaintext journaled before the ratchet moves and kept until acknowledged; typing indicators sent outside the ratchet; a payload must match its envelope kind Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley: Initializr template synced Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Flutter bench: PR overlay re-measured on top of master's moved JavaScript size row Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Parley CI: server tests on PostgreSQL and MySQL, as Savor and Wayline run them Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Baselines: repair #5976's merged overlays (rows master already moved are dropped or re-anchored); Parley's own JS size overlay is covered by #5976's and goes Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Flutter bench: Parley's JavaScript and Linux size rows, measured on top of master Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Flutter bench: re-measure Parley's Linux size rows on top of current master Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Flutter bench: re-measure Parley's Linux zipped download on top of current master Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * JavaScript screenshots: present the phone-sized harness as a touch-only pointer #6073 gives any browser with a fine pointer desktop scrollbars.
