From 584c02526f660b48b9f04ed916a630b6191d5ee3 Mon Sep 17 00:00:00 2001 From: Kevin Harder Date: Tue, 26 May 2026 14:05:47 -0500 Subject: [PATCH 01/47] Gate self-content draws on needsDrawSelf to stop child-only redraw fan-out Capture NeedsDraw at the top of View.Draw() before DoDrawAdornments mutates NeedsDrawRect, and gate DoClearViewport / DoDrawText / DoDrawContent on the captured value. When a parent enters Draw() only because SubViewNeedsDraw is true, its viewport is no longer cleared and its own text/content is no longer redrawn. Adornments, subviews, and line canvas still render correctly.

Add a DrawingText counter to both the diagnostic and integration tests — DrawingText is gated on NeedsDraw inside DoDrawText and is not intercepted by Code (which does intercept ClearedViewport / DrawingContent via OnClearingViewport / OnDrawingContent returning true). Use DrawingText to verify per-Code inactive-tab behavior, and use tabsCounts.ClearedViewport to verify the parent's own behavior. TabsFanOutDiagnosticTests (synthetic Layout/Draw path) now asserts: - inactive tabs have DrawingText == 0 - Tabs container has ClearedViewport == 0 - text-draw fan-out ratio == 1.0 (parity with single-Code baseline) TabsFanOutIntegrationTests (end-to-end via main loop) keeps the existing "documents remaining fan-out" assertion: a separate cascade source remains in ApplicationImpl.LayoutAndDraw (force=true when neededLayout, calling SetNeedsDraw on the top runnable which cascades to overlapping subviews). Removing that force=true uncovers stale-content bugs in the shrink/move path (already covered by ShadowTests / BorderViewTests) and is out of scope for #5358.

The result was that NeedsDrawRect was effectively clamped to the current Viewport size on every call — accumulated partial regions were silently widened to ~viewport-wide, making NeedsDrawRect useless for narrowing draw work. Replace with Rectangle.Union (NeedsDrawRect, viewPortRelativeRegion) so NeedsDrawRect accurately tracks the accumulated dirty area. This is required for issue #5358's region-aware ClearViewport.

Coordinate-space inconsistency. SetNeedsDraw(Rectangle) cascades to subviews using frame-local coordinates (subtracts subview.Frame.X/Y), while the no-arg variant passes content-coord Viewport. For an unscrolled view those coincide; for a scrolled view they disagree, and my narrowing math (subtracting Viewport.X/Y) would shift the clear off-screen on a scrolled subview. 2. Code/MarkdownCodeBlock full-clear contract. Both call public ClearViewport() from their OnClearingViewport overrides expecting a full fill of the code-block background. With NeedsDrawRect set partial by the cascade, the narrowed clear left stale background in the un-cleared part of the viewport (visible when content has fewer lines than the viewport, etc.). Fix: revert public ClearViewport() to always full-clear. Move narrowing logic into a private CanNarrowClearToNeedsDrawRect helper invoked only from DoClearViewport (the framework's draw-pipeline entry point), guarded by Viewport.Location == Point.Empty so the scrolled-cascade ambiguity is sidestepped entirely. The Item 1 normalization (frame-local vs content-coord NeedsDrawRect) is a deeper refactor deferred as a follow-up. 3. TransparentMouse hit-region wipe. _localDrawContext was recreated unconditionally before the needsDrawSelf gate, but on child-only passes DoDrawText/DoDrawContent are skipped, so _localDrawContext stayed empty. DoDrawComplete then wrote that empty region into CachedDrawnRegion, breaking mouse hit-testing for transparent views until the next full self-redraw. Fix: only recreate _localDrawContext when needsDrawSelf is true. On child-only passes the prior context is preserved, so DoDrawComplete keeps the previously- cached drawn region. SetNeedsDraw nulls CachedDrawnRegion when the view is genuinely invalidated, so stale cache values are bounded by view lifecycle. Updated tests: - RegionAwareClearViewportTests: switched from testing the public ClearViewport API to testing the framework's DoClearViewport via Draw(). Added a FrameworkDraw_ScrolledView_FallsBackToFullClear test that locks in the scrolled-view guard from fix 1. - SubViewOnlyRedrawTests: added TransparentMouseParent_ChildOnlyDirty_ PreservesCachedDrawnRegion to lock in fix 3.

Enter_In_TextField_On_Last_Step_Requests_Stop: OnAccepting returns false on last step, bypassing Dialog.OnAccepting which calls RequestStop(). Wizard doesn't close when Enter is pressed in content view on last step. 2. MovingBack_Cancel_Does_Not_Bubble_Accept: BackBtnOnAccepting doesn't set e.Handled when MovingBack is cancelled, so accept bubbles to the dialog.

OnAccepting on last step: call base.OnAccepting(args) instead of returning false, so Dialog.OnAccepting can call RequestStop() in modal mode. Without this, Enter from content views on the last step won't close the wizard. 2. BackButtonOnAccepting: set e.Handled = true when MovingBack is cancelled, preventing accept from bubbling up to the dialog. Tests verify both fixes and fail without them.
