Two independent Opus reviews of 01b98ca30 (Slice A - movable, collapsible
plugin shelf) found blocking design and behavior issues plus several
should-fix gaps. All addressed in this commit:
1. Grip/toggle are now REAL children instead of a drawn band + a
cursor-position-dependent HandlesClick override + an OnEvent toggle
hack: ShelfGripPanel (WindowMoveHandle=true) spans the top band minus
the toggle width; a UiSimpleButton toggle sits beside it (HandlesClick
already wins at UiRoot.OnMouseDown before the Draggable-window
fallback). The shelf's own Draggable is now FALSE - verified against
UiRoot.FindDragHandleWindow, which never reads a window's own
Draggable flag at all (it walks for a WindowMoveHandle ancestor-or-self
then climbs to the nearest child of UiRoot), so Draggable=true was
never required for the grip to work and only armed the whole-window-
drag fallback for clicks on the shelf's own padding - exactly the
behavior the review asked NOT to have. The two Assert.Single(shelf.
Children) test sites now filter by the (now internal) PluginShelfButton
type instead of asserting child count.
2. Deleted the per-tick "always highest ZOrder" raise in OnTick. It fought
RetailDialogFactory.Tick's own per-frame dialog re-raise, so a dialog
opened while the shelf was visible could never end up on top of it.
Registration's ordinary press-to-raise (a grip press calls
BringToFront before the drag starts) remains.
3. Collapse and hide/show intent are now persisted through their own
channel. RetainedWindowState gained a nullable RequestedVisible;
RetailWindowHandle gained an internal StateChanged event that
RetailWindowLayoutPersistence subscribes to (alongside Moved/Resized/
Shown/Hidden) and that the shelf raises after a collapse toggle or
Show/Hide. Capture() now persists state.RequestedVisible (the panel's
own intent) instead of the derived IsVisible, so an availability hide
(last plugin window unregistered) is never mistaken for a user hide.
WindowNames.PluginShelf is now one of RetailUiRuntime's state-managed
visibility windows, so Apply() restores the intent through
RestoreWindowState directly rather than via Show()/Hide().
4. RetailWindowLayoutPersistence now subscribes to
RetailWindowManager.WindowRegistered/WindowUnregistered so a window
(a plugin window loaded after startup, or the shelf on any path that
constructs persistence first) attaches even when it registers after
persistence already exists.
5. Reflow()'s default height argument is now nullable and falls back to
the last height OnTick actually measured (or unbounded if none yet),
instead of always forcing a single-column layout - every call site
OTHER than OnTick's own row-wrap (Add, unregister, Show/Hide, the
collapse toggle, RestoreWindowState) used to collapse a wrapped
multi-column layout to one column for a frame.
6. _userPositioned is now flipped only when the handle's position differs
from the recorded dock placement, not on every RetailWindowHandle.
Moved (which fires unconditionally on any completed window-drag
release, including a zero-movement grip click, and on any
ClampAllToScreen reachable-clamp).
7. New tests cover: a press+drag starting on an entry button does not
move the shelf; the removed per-tick raise (a sibling with higher
ZOrder keeps it after a tick); TogglePluginManager's hidden-and-
collapsed -> shown-and-expanded / visible -> hidden transitions at the
shelf API (no RetailUiRuntime construction harness exists in this test
suite to exercise the action-routing switch itself - the "no plugin
windows registered" message branch is therefore not covered here).
8. The hide branch of TogglePluginManager now displays "Plugin shelf
hidden. Press Shift+Ctrl+F1 to show it again."; the show branch stays
silent.
9. The collapse toggle now draws ASCII '<'/'>' instead of the DAT-font-
dependent '«'/'»' glyphs (the only use of those code points in the App
UI, silently dropped by UiDatFont when absent), and gets the same
DatFont + bitmap fallback the shelf's entry buttons already have
through UiSimpleButton. A new installed-DAT test pins that the default
font actually carries both ASCII glyphs.
10. ResizeX/ResizeY are false on the shelf so a restored layout's saved
dimensions can never stomp the derived Width/Height via ResizeTo.
11. WindowNames.PluginShelf replaces the "plugin-shelf" literal at every
site (RetailUiRuntime, docs comments, tests).
12. The grip dims to half opacity while RetailWindowManager.IsLocked, the
same visual cue every other retail window gets (the shelf's grip has
no DatElementId, so RetailWindowLockPresentationController's authored-
chrome dimming does not reach it on its own).
Every new test was verified to fail against the pre-fix source: reverting
src/AcDream.App/UI/PluginSidePanel.cs, IRetainedWindowStateController.cs,
RetailWindowHandle.cs, WindowNames.cs, and RetailUiRuntime.cs to their
01b98ca30 state makes the whole PluginSidePanelTests.cs file fail to even
compile (missing WindowNames.PluginShelf, the now-internal
PluginShelfButton type, and RetainedWindowState.RequestedVisible);
reverting RetailWindowLayoutPersistence.cs alone (fixed source elsewhere)
makes WindowRegisteredAfterConstruction_StillRoundTrips fail at runtime
with a null saved layout, confirming finding 4 in isolation.
Verified: dotnet build src/AcDream.App (Release) green; dotnet test
tests/AcDream.App.Tests (Release) targeted filter
(PluginSidePanel|RetailWindowLayout|Markup|UiRootInput) 105/105 green;
full suite 7303 passed / 97 skipped / 36 failed (identical failure set to
the pre-fix-round baseline - installed-DAT live-mount probes, Linux-only
pacing/credential tests, and alpha-flush COUNT-only conformance
divergences, none touching plugin UI; +9 tests, all passing, over the
prior 7294/97/36 baseline).
