From ffe141804b1277ae1c858f046737ec049017d6c3 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 19 May 2026 15:39:21 +0000 Subject: [PATCH 01/17] fix(patches): implement convert_pointer_data; split events into submodules MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add HasPointerData impl to NativeClickData in dioxus-native-dom patch, synthesising a mouse-type primary pointer from the BlitzMouseButtonEvent. Fixes the unimplemented!() panic that would fire on any onpointerdown / onpointermove handler in Phase 3 tool input routing. - Split the monolithic events.rs (386 lines) into events/{mod,mouse,keyboard, form,touch}.rs to respect the 300-line / 100-line mod.rs ceilings. - Remove the fontique patch entry from workspace Cargo.toml; the patch declared version 0.8.0 but blitz-dom 0.2.4 resolves fontique 0.6.0, so the patch never applied and generated a spurious cargo warning. The build is clean without it; re-evaluate if fontconfig_sys linkage errors appear on CI Linux. Which case applied: CASE B (HtmlEventConverter panics NOT fixed upstream). The dioxus-native-dom patch IS applying (to 0.7.9 — dioxus 0.7.4 depends on native-dom 0.7.9 internally). convert_mouse_data already worked; convert_pointer_data now delegates to the same NativeClickData path. No unused-patch warnings remain. https://claude.ai/code/session_012imcXHNWwg8q1TNRo1un9K --- Cargo.lock | 4 - Cargo.toml | 7 +- .../patches/dioxus-native-dom/src/events.rs | 348 ------------------ .../dioxus-native-dom/src/events/form.rs | 44 +++ .../dioxus-native-dom/src/events/keyboard.rs | 45 +++ .../dioxus-native-dom/src/events/mod.rs | 84 +++++ .../dioxus-native-dom/src/events/mouse.rs | 122 ++++++ .../dioxus-native-dom/src/events/touch.rs | 88 +++++ 8 files changed, 386 insertions(+), 356 deletions(-) delete mode 100644 crates/patches/dioxus-native-dom/src/events.rs create mode 100644 crates/patches/dioxus-native-dom/src/events/form.rs create mode 100644 crates/patches/dioxus-native-dom/src/events/keyboard.rs create mode 100644 crates/patches/dioxus-native-dom/src/events/mod.rs create mode 100644 crates/patches/dioxus-native-dom/src/events/mouse.rs create mode 100644 crates/patches/dioxus-native-dom/src/events/touch.rs diff --git a/Cargo.lock b/Cargo.lock index 1982cad..3723385 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -8853,7 +8853,3 @@ dependencies = [ "syn 2.0.117", "winnow 1.0.3", ] - -[[patch.unused]] -name = "fontique" -version = "0.8.0" diff --git a/Cargo.toml b/Cargo.toml index 890418d..0f1302b 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -66,10 +66,9 @@ bytemuck = { version = "1", features = ["derive"] } png = { version = "0.17" } [patch.crates-io] -# PATCH: fixes missing fontconfig_sys alias and dlopen/static feature-unification -# conflict with blitz-dom's fontique 0.6 — remove when fontique >0.8.0 on -# crates.io restores the alias and resolves the linkage conflict. -fontique = { path = "crates/patches/fontique" } +# COMPAT(dioxus): fontique patch removed — blitz-dom 0.2.4 resolves fontique 0.6.0 +# from crates.io directly; the 0.8.0-based patch was version-mismatched and never +# applied.

fires when blitz-shell routes MouseWheel to Dioxus — currently blitz 0.2.x consumes at CSS scroll level; see TODO comment in canvas_widget.rs §11.2). - Ctrl+wheel zooms via viewport.zoom_to(); plain wheel pans viewport.pan. iris-app: - Add tool_dispatch.rs: dispatch_tool_event routes by ToolMode; pixel path logs Down/Move/Up/Scroll/Pinch with doc coordinates. - Wire CanvasArea → IrisCanvas on_tool_event → dispatch_tool_event. dioxus-native-dom patch: - Add events/wheel.rs: NativeWheelData stub implementing HasWheelData; prevents convert_wheel_data from panicking when a future blitz version routes wheel events through Dioxus. Scroll/pinch via wheel requires a blitz-shell patch to call handle_ui_event for MouseWheel; tracked as TODO(iris) SPEC.md §11.2. Mouse down/move/up events fire and dispatch correctly. https://claude.ai/code/session_012imcXHNWwg8q1TNRo1un9K --- crates/iris-app/src/canvas_area.rs | 3 + crates/iris-app/src/main.rs | 1 + crates/iris-app/src/tool_dispatch.rs | 63 ++++++++++++++ crates/iris-canvas/src/canvas_widget.rs | 87 +++++++++++++++++++ crates/iris-canvas/src/lib.rs | 2 + crates/iris-canvas/src/tool_event.rs | 53 +++++++++++ .../dioxus-native-dom/src/events/mod.rs | 13 ++- .../dioxus-native-dom/src/events/wheel.rs | 63 ++++++++++++++ 8 files changed, 284 insertions(+), 1 deletion(-) create mode 100644 crates/iris-app/src/tool_dispatch.rs create mode 100644 crates/iris-canvas/src/tool_event.rs create mode 100644 crates/patches/dioxus-native-dom/src/events/wheel.rs diff --git a/crates/iris-app/src/canvas_area.rs b/crates/iris-app/src/canvas_area.rs index 47ac26b..f8580a8 100644 --- a/crates/iris-app/src/canvas_area.rs +++ b/crates/iris-app/src/canvas_area.rs @@ -64,6 +64,9 @@ pub fn CanvasArea(mut state: Signal) -> Element { viewport: viewport_signal, width: CANVAS_WIDTH, height: CANVAS_HEIGHT, + on_tool_event: move |evt| { + crate::tool_dispatch::dispatch_tool_event(evt, state);

BrushEngine (src/brush.rs): - Hard round brush with pressure-sensitive size (size_px * pressure) - Softness falloff: hardness 0.0–1.0 controls the feather zone - Sub-pixel spacing interpolation between ToolEvent::Move positions - Porter-Duff "over" compositing into f16 RGBA TileData - erase_mode flag uses destination-out instead of over EraserEngine (src/eraser.rs): wraps BrushEngine with erase_mode=true. Wired into iris-app: - PixelToolState added to AppState (brush + eraser engines) - dispatch_pixel_tool calls on_down/on_move/on_up per ToolEvent - canvas_dirty flag triggers tree_signal sync in canvas_area.rs so IrisCanvasPaintSource composites the painted tiles on next frame - selected_layer initialised to Background layer in AppState::default - Viewport pan initialised to (doc_w/2, doc_h/2) so doc (0,0) is at canvas top-left at zoom=1 (fixes brush landing in negative tile coords) Fix: read-guard from match state.read().tool_mode was kept alive across dispatch_pixel_tool causing AlreadyBorrowed panic on state.write(); resolved by binding tool_mode before the match.

On a 2x Retina display, width=2288, height=1266 while the correct logical CSS size is 1144×633. Storing physical dimensions in shared_size caused screen_to_doc() to use a wrong canvas center (1144,633) instead of (572,316), creating a fixed 572px horizontal offset. On maximize the physical dimensions grew further, making the offset proportionally worse — exactly the "maximizing makes it more pronounced" symptom. Fix: divide width/height by scale at the very top of render() before any early returns, storing the logical CSS size. Also restored the onmounted path as a belt-and-suspenders fallback (fires with logical Taffy layout size in CSS pixels, same value). https://claude.ai/code/session_012imcXHNWwg8q1TNRo1un9K --- crates/iris-canvas/src/canvas_widget.rs | 30 +++++++++++++++++-------- crates/iris-canvas/src/paint_bridge.rs | 29 ++++++++++++++++-------- 2 files changed, 41 insertions(+), 18 deletions(-) diff --git a/crates/iris-canvas/src/canvas_widget.rs b/crates/iris-canvas/src/canvas_widget.rs index ee940cb..bf43492 100644 --- a/crates/iris-canvas/src/canvas_widget.rs +++ b/crates/iris-canvas/src/canvas_widget.rs @@ -115,10 +115,11 @@ pub fn IrisCanvas(props: IrisCanvasProps) -> Element { let on_up = props.on_tool_event.clone(); let on_wheel = props.on_tool_event.clone(); // Clone Arc once per closure — Arc is Clone, not Copy. - let size_down = shared_size.clone(); - let size_move = shared_size.clone(); - let size_up = shared_size.clone(); - let size_wheel = shared_size.clone(); + let size_down = shared_size.clone(); + let size_move = shared_size.clone(); + let size_up = shared_size.clone(); + let size_wheel = shared_size.clone(); + let size_mounted = shared_size.clone(); rsx! { div { @@ -132,17 +133,28 @@ pub fn IrisCanvas(props: IrisCanvasProps) -> Element { background-color: #1e1e1e;", onmounted: move |evt| { - // Log the mounted dimensions for diagnostics.

The compositor was calling doc_to_screen() with physical dims while the event handler called screen_to_doc() with logical dims — producing mismatched center anchors that caused the painted stroke to drift from the cursor by an amount proportional to the distance from canvas center.
