…ow alone Measured on 2026-09-16 through the canvas: two presses on the title of a section left it shut, and the arrow after the title was the only target. The owner's decision is that the whole row is one target. The row is one control now, FoldHead: it answers the pointer anywhere on the row - the title, the arrow, the line a closed section shows, the room to the right up to a batch's own buttons - and the keyboard as one stop, with a fill under the pointer and a ring for the keyboard. The arrow is a mark on it rather than a button of its own, inked like the words at rest and brighter under the pointer. The control is a hit layer under the row's content rather than a widget holding the title: the guards that read titles walk containers and stop at a widget they were not told about, so a title inside a renderer would be a title nothing reads. The row keeps TabInset inside its box for the fill and the ring to draw in, and overhangs the column by the same amount so the title's ink stays on the edge everything else starts on. Four guards press the row through the canvas on the real window and assert that each press changed the fold, because a row and an arrow both answering would leave it as it was. The twenty-one stored screens that carry a section are regenerated. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Keep the arrow inside the FoldHead hit layer.
Padded places the 744-pixel content at x=8. The title and gap place the 20-pixel arrow at x=746..766 relative to the 760-pixel FoldHead. Fyne v2.8.1 excludes points at or beyond the object's right edge from hit testing, so the final 6 pixels cannot reach FoldHead.Tapped.
Constrain or truncate the title to reserve space for the arrow and its gap, then regenerate this fixture.

Expose FoldHead to Fyne accessibility dispatch.
Fyne v2.8.1 accessibility drivers type-assert each canvas object to fyne.Accessible. Since FoldHead does not implement that interface, the interactive row is omitted and receives no announced label or button role.

Fyne v2.8.1 focus_manager.go Canvas.Focus already focused FocusGained
💡 Result:
<search_synthesis>
In Fyne v2.8.1, the focus management logic is handled by the internal FocusManager, which ensures that focus transitions are clean and prevent redundant state updates [1][2]. If you are observing behavior where a canvas object appears to trigger FocusGained when it is already focused, or if you are manually calling methods that interact with focus, it is important to understand how the FocusManager and Canvas.Focus operate: 1. Redundancy Check: The FocusManager internal method focus(obj fyne.Focusable) explicitly checks if the target object is already the focused object [1]. If f.focused == obj, the function returns early without triggering redundant FocusLost or FocusGained events [1]. 2. Canvas.Focus Logic: When you call Canvas.Focus(obj), it routes the request through the focus manager [3]. The focus manager validates that the object is part of the canvas tree (i.e., visible and not disabled) before attempting to change the focus [1]. 3. FocusGained vs. Focus: The FocusGained() method on the Canvas is a signal that the entire application or window has regained focus from the operating system [4][2]. This is distinct from Canvas.Focus(obj), which sets the specific focus to a particular widget [4][5]. Calling FocusGained() on the canvas tells the focus manager to inform the currently focused object (if any) that it should react as if it just regained focus [1][6]. If you are experiencing unexpected behavior, consider these points: - Ensure the widget you are attempting to focus is already added to the canvas tree [7]. Attempting to focus an object not yet in the widget tree will fail [1][7]. - Do not attempt to modify the canvas state (including further changing focus or showing/hiding elements) inside a FocusGained or FocusLost method, as this can cause deadlocks or infinite loops [8]. - If you are seeing FocusGained firing unexpectedly, verify if external OS-level window focus changes are triggering the Canvas's FocusGained method [1][9]. For most use cases, you should rely on Canvas.Focus(obj) rather than manually triggering FocusGained [10]. If you are developing a custom widget, ensure it correctly implements fyne.Focusable and that its FocusGained method only performs intended UI updates [8].

Separate keyboard activation from pointer focus handling.
When keyboard focus sets marked, a pointer tap on the already focused FoldHead calls c.Focus(h) without invoking FocusGained again. The current Tapped method does not clear marked, so the keyboard ring can remain visible.
Clear marked only in Tapped. Toggle directly from TypedKey so keyboard activation keeps its current behavior.

What
Until now only the small arrow after a section's title opened or closed the section. A click on "Notes for the manifest" or "Settings for png" did nothing (O221, measured on 2026-09-16 with
test.TapCanvas: two presses on the title, section still shut). The owner's decision: the whole head row is one target.The row is now one control,
parts.FoldHead:DuplicateandRemovein a batch's head keep doing their own job,TabInsetinside its box and overhangs the column by the same amount (overhanglayout), so the ink does not move.Why this shape
FoldHeadis a hit layer under the row's content (WithRingthe other way up), not a widget holding the title. The guards that read titles walk containers and stop at a widget they were not told about, so a title inside a renderer would be a title nothing reads.The alternative - keep the arrow as a button and make the row tappable around it - was rejected: the driver keeps one object under the pointer, so the row's highlight would go out when the pointer reached the arrow, which would light its own. Two targets pretending to be one.
Proof
foldhead_test.go: four guards on the real laid out window. Four presses through the canvas (title, arrow, empty room, top edge), each asserted to CHANGE the fold - a row and an arrow both answering would leave it as it was.Duplicatein the same row: one more batch, fold untouched. Keyboard: Space delivered as key AND character changes the fold exactly once. States read from the renderer's rectangles, not from a flag.try-namedon this branch: 8 of 8 caught.🤖 Generated with Claude Code
