gui: no screen stands in a theme override any more - the window's fonts are parsed twice rather than once per line - #129

…eme override inkTight wrapped every sentence that wraps - an error area under each field, the status line, captions - in a container.ThemeOverride. Fyne gives an override a new scope at construction, at CreateRenderer and at every Refresh, and keys its parsed fonts by scope, so every rebuild of a screen followed by a new string in one of those labels parsed another ~7.4 MB set of fonts that nothing frees. Measured in the real window, interleaved: 26 sets after visiting the tabs, 19 of them this override's; without it 7, and the live heap there 205 MB -> 64 MB. The layout gives the label its inner padding outside the room it is handed, so the words land and wrap where a label with no inner padding puts them. All 28 stored screens are pixel for pixel the same (the guard's tolerance is 0 on amd64 and it rewrote no picture); their trees change from an override to a container.

…rride, and no screen holds an override any more QuietText is a rich text with the segment widget.Label builds for itself, the hint's colour in place of the disabled one (O213), drawn ink tight by the same layout as inkTight. It replaces quiet(label) - the subtitle, the caption, the note, a folded section's line and the count of bytes - which put each of them under a container.ThemeOverride: a new scope at every Refresh, and a fresh ~7.4 MB set of fonts for every new string drawn in one. Measured in the real window, interleaved with main (two runs each): - after visiting the tabs: live heap 205 MB -> 27 MB, process 287-310 MB -> 113-131 MB, font sets 26 -> 2; - ten rebuilds each followed by a new size: live 289 MB -> 30 MB, and nothing added by the rebuilds. All 28 stored screens are pixel for pixel the same. One would not have been: a folded section's line sat inside an override that stayed visible while the line was hidden, and the row kept a gap for it - the line now stands in a container that never hides, so the open head keeps its right inset. Guards read QuietText and ByteCount as words (wordsOf), and measure a line drawn ink tight by the room it was given (labelBox). New guard: TestNoScreenStandsInAThemeOverride. The open list of formats still draws its rows under one - the next change. Co-Authored-By: Claude Opus 5.5 <[email protected]>

- Line 478: Update the window-memory changelog heading to limit its claim to
screen rebuilds: state that rebuilds no longer increase memory, without implying
memory never grows with use. Keep the format-filter memory growth limitation
accurately represented in the entry.
In `@internal/gui/parts/quiet.go`:
- Line 35: Implement fyne.Accessible on QuietText by adding AccessibilityLabel()
and AccessibilityRole() methods that expose its text and return the text role.
This also gives ByteCount the accessibility metadata through its embedded
QuietText.
- Line 71: Remove the redundant q.rich.Refresh() call from QuietText.Refresh;
keep q.sync() and q.BaseWidget.Refresh() so the renderer refreshes the RichText
once.

Restore the text accessibility contract.
QuietText replaces widget.Label, but it does not implement fyne.Accessible. In Fyne v2.8.1, a label exposes its text and text role through that interface. The contained RichText does not implement it, so captions and byte counts lose their text accessibility metadata. Implement AccessibilityLabel() and AccessibilityRole() on QuietText. ByteCount will inherit both methods. (github.com)
Proposed fix
type QuietText struct {
widget.BaseWidget
// ...
}

+var _ fyne.Accessible = (*QuietText)(nil)
+
+func (q *QuietText) AccessibilityLabel() string { return q.Text }
+func (q *QuietText) AccessibilityRole() fyne.AccessibleRole {

…ly what was measured QuietText.Refresh refreshed its rich text itself and then again through the renderer, whose container refreshes every child - the shape copied from widget.Label, surplus included. The count of bytes redraws on every key. All 28 stored screens stay pixel for pixel the same, generate-typed among them, whose count is drawn after the first frame. The changelog heading said the window no longer grows with use while the same entry says the filter of the format list still does. It now says what was measured: rebuilding a screen no longer adds to it. Co-Authored-By: Claude Opus 5.5 <[email protected]>

What was wrong
Measured in the real window with
tools/probes/guilag(reads Fyne's font cache and its count of theme-override scopes):container.ThemeOverridea new scope at construction, atCreateRendererand at everyRefresh, and keys its parsed fonts by scope. A new string drawn in a new scope parses a fresh ~7.4 MB set of fonts that is never freed.inkTight: error areas, status line, titles) and every quiet line (quiet: subtitle, caption, note, folded section line, count of bytes) stood in one. 26 font sets after visiting the tabs, and each rebuild of a screen followed by a new string added more.What changed
inkTighttakes the label's inner padding off with a layout (label placed one padding up/left, one larger per side) instead of a theme override.QuietText- a rich text with the segmentwidget.Labelbuilds for itself, in the hint's colour (O213) - replacesquiet(label).ByteCountembeds it.wordsOfreadsQuietText/ByteCount,labelBoxmeasures a line drawn ink tight by the room it was given. NewTestNoScreenStandsInAThemeOverride.All 28 stored screens are pixel for pixel the same (the guard's tolerance is 0 on amd64 and it rewrote no picture); only their trees change.
Measured after (interleaved with
main, two runs each)Not in this PR
The open list of formats still draws its rows under a theme override (
rowTheme), and its filter makes each opening with a new letter parse two more sets: +158 MB over ten openings. That is the next change.🤖 Generated with Claude Code
