Bug #331: "Il serait intéressant de pouvoir directement dans la fenêtre
'Sélection numérotation auto' modifier la valeur d'incrément et visualiser
la prochaine numérotation qui sera appliquée. Ceci sans être obligé
d'ouvrir la page de configuration."
The dock (AutoNumberingDockWidget) already let you see and edit a rule's
*current* value inline (added in 52c8ef6b4/031710b5f/ee4ba82d2). The
increment itself, and any preview of where the numbering is headed, was
reachable only through Configurer -> the full project-properties dialog.
Two new widgets per row (conductor/element/folio):
- An increment spin box, read from and written to the same NumerotationContext
field NumPartEditorW's increase_spinBox already edits in the full dialog --
same data, second place to reach it.
- A read-only next-value field, computed via
NumerotationContextCommands::next() -- the identical engine the "Suivant"
button in the full dialog already uses to step a whole context. Reusing it
rather than reimplementing the arithmetic means wrap-and-carry between parts
comes out identical to what actually happens when the number is next
consumed, and zero-padding matches real rendering
(NumerotationContext::formatValue(), mirroring
autonum::setSequentialToList()'s padding rule by hand since that function is
local to assignvariables.cpp).
NumerotationContext gains replaceIncrease(index, increase), a sibling to the
existing replaceValue() that touches only the increment field.
Every refresh call site in the file (13 of them) previously refreshed just the
value field; they now go through a new refreshRow(category), which refreshes
value + increment + next-value-preview together via a small per-row widget
bundle (rowFor()). This also let resetAutoNum()'s three-way switch collapse to
one line, and refreshValueFields()'s three near-identical blocks collapse to a
loop -- both existing before this change, not new here.
Verified live under Xvfb: created an element numbering rule "K" (Chiffre 1,
value 1, increment 1) via the full dialog, confirmed the dock showed
Valeur=1/Incrément=1/Suivant=2. Changed the dock's own Incrément to 3 --
Suivant updated live to 4, no dialog needed. Changed Valeur to 10 -- Suivant
became 13. Reopened the full configuration dialog and confirmed it read back
the same value_field=10/increase_spinBox=3, i.e. the round trip through
replaceIncrease()/storeContext() does not disturb type, initial value, modulus
or format.
Builds clean, CMake/Ninja Release, Qt 5.15, 820/820, no new warnings.

Bugtracker #308: the "current date" preset for a project's default
title block doesn't persist. A later comment on the report pinpointed
it exactly: the setting falls back to "No date" unless the folio tab
remains active when saving settings, and the same happens in Project
Properties.
TitleBlockPropertiesWidget::properties() (and its near-duplicate
sibling propertiesAutoNum(), copy-pasted with the same bug) reads the
date radio buttons like this:
else if (ui->m_current_date_rb->isVisible() && ui->m_current_date_rb->isChecked()) {
prop.useDate = TitleBlockProperties::CurrentDate;
...
Both the New Project settings page and Project Properties embed this
widget as one page of a QTabWidget (NewDiagramPage, in
configpage/configpages.cpp). QWidget::isVisible() depends on the
whole ancestor chain being visible, not just the widget's own state --
switch to any other tab before clicking OK/Apply and this radio
button's isVisible() goes false even though it's still checked
underneath, silently falling through all three branches. The function
returns a default-constructed TitleBlockProperties for the date
fields (useDate = UseDateValue, date = QDate(), i.e. "no date"),
matching exactly what was reported.
Fix: use isHidden() instead, which reflects only this widget's own
explicit state and mirrors the read side's own check in
setProperties()/initDialog() just above it in the same file -- that
side already uses isHidden(), not isVisible(), for the identical
"is the current-date option even offered here" question.
Verified directly: a standalone Qt program constructing the real
NewDiagramPage, checking "current date", switching the tab widget
away from Folio to Conducteur (reproducing the report's exact
trigger), then calling applyConf() and reading back the QSettings
value. Against the original code this saves date="null"; with the
fix, date="now" -- the same scenario, same tab switch, only the one
line differs. Also confirmed a full Release build (504/504, CMake/
Ninja, Qt 5.15.18) with no new warnings.
Bugtracker #335: element library icons are black and nearly invisible
under a dark desktop theme (reported on KDE Plasma / Fedora 43).
The main elements panel (ElementsCollectionWidget) already forces a
fixed light palette on its tree views via ElementsTreeView, added in
a8e2a7acf and completed in bb61dde81 -- element icons are rendered
with colors read from each .elmt file (almost always black linework,
matching printed-schematic convention) onto a transparent
background, so any view showing them needs to stay light regardless
of the OS theme. ElementsTreeView's own class doc already says
"This class must be used when the tree view have an
ElementsCollectionModel as model" -- but two other dialogs showing
the exact same model were still using a plain QTreeView and missed
that fix: the Open/Save Element/Category/Template dialog
(ElementDialog) and the New Element Wizard's parent-category picker
(NewElementWizard). Same underlying ElementsCollectionModel, same
black-on-transparent icons, same invisibility on a dark theme.
Fix: use ElementsTreeView in both, matching the main panel and the
class's own documented contract. No other behavior changes --
ElementsTreeView only additionally overrides startDrag() to use a
nicer drag pixmap, which is inert unless drag-out is enabled.
Verified with a full Release build (504/504, no new warnings) and a
standalone Qt program that shows the real ElementDialog under a
forced dark QPalette (simulating a dark OS theme, since neither this
build environment nor QET itself forces the palette one way or the
other): screenshots down through nested collection categories
(Electric > IEC 60617 > Conductors and connecting devices) confirm
the tree view keeps a white background against the dark dialog
chrome around it.
NewDiagramPage::applyConf() writes every other default to QSettings —
border, title block, conductors, folio reports and the guides — but the
cross-reference branch only fetched the properties into a local hash and
then dropped it on the floor. hash_xrp was never used.
The result: changing the cross-reference defaults under Settings > New
project has no effect. Nothing is written, no defaultxref* key ever
appears in the configuration file, and XRefProperties::defaultProperties()
keeps handing out the hardcoded fallbacks for every new project.
Write each of the four types (coil, protection, commutator, plc) with the
"diagrameditor/defaultxref" + key prefix that defaultProperties() already
reads back.
Both actions already exist and work; they were simply only reachable from
a toolbar, and those toolbars are user-hideable via Configuration >
Afficher, so hiding one made the feature unreachable entirely.
- "Afficher les guides" (m_draw_guides) goes into the Affichage menu next
to "Afficher la grille". The two are adjacent lines in the view toolbar
and do the same kind of thing, but only the grid had a menu entry.
- "Creation automatique de conducteur(s)" (m_auto_conductor) goes into the
Projet menu. It writes a project setting via
QETProject::setAutoConductor(), so the Projet menu is where a user would
look for it; it is placed with the project properties, above a separator
that keeps the folio operations grouped as before.
Also removes conductor_default and m_project_folio_list from the header.
Both are declared but never allocated and never referenced anywhere in the
tree -- that the build still links is the proof they were dead.
No new strings: both actions already carry translated text.
Found while auditing every QAction against every menu, discussion #677.

QetLogger (discussion #644, steps 1-3) captures whatever an explicit
qDebug()/qInfo()/qWarning() call already decided to report. Most of a
session -- painting, dragging, a slow synchronous operation -- produces
no log output at all, so a silent multi-second gap in the log is
indistinguishable from the user simply not doing anything. That gap
came up directly: investigating a user-reported "the program lagged"
required inferring stalls from timestamp gaps between unrelated log
lines, which can't tell a real freeze apart from normal idle time.
EventLoopWatchdog closes that gap directly instead of inferring it. A
QTimer::PreciseTimer repeating tick (every 50ms) measures the *actual*
elapsed time since the previous tick via QElapsedTimer (monotonic,
unaffected by system clock/NTP adjustments). Qt does not queue up
missed fires for a normal repeating timer, so if the main thread is
blocked for 600ms, the timer fires once as soon as the loop frees up,
with ~600ms measured since the last tick -- that gap is the stall,
measured at its source. Only logs (via the existing qWarning() path,
so it reuses QetLogger's file/ring/rotation with no new plumbing) when
a tick is late by more than 200ms, so a healthy session produces zero
output from this class, in keeping with QetLogger's bounded-log design.
Same QET_WATCHDOG_DISABLE=1 escape-hatch convention as QetLogger's own
QET_LOG_DISABLE=1.
Deliberately not included: attributing a stall to what caused it. This
tells you a stall happened and how long -- pairing that timestamp with
gdb attached to a running session (as used for the CLI hang, PR #661)
is still how you get from "it stalled" to a root cause.
Stacked on #647 (feature-diagnostic-logging-crash) for QetLogger/
qWarning() plumbing this depends on -- diff includes its commits until
that merges.
Verified against the compiled binary, not just read: temporarily
injected a QThread::msleep(600) via a one-shot QTimer 2s after
startup, confirmed the exact expected warning
("EventLoopWatchdog: main thread stalled for 620 ms") at the right
severity through the real qWarning()/QetLogger path, then removed the
test hook and reconfirmed a normal run produces no output from this
class at all.
Stacked on the steps 1-3 branch (feature-diagnostic-logging, PR #646).
Kept as its own PR rather than folded into that one, matching the
discussion's own framing: step 4 is explicitly "the highest-risk piece
... lands last, behind its own switch."
## Step 4 -- crash-time ring flush (CrashHandler)
Installs a handler for SIGSEGV/SIGABRT/SIGBUS/SIGFPE/SIGILL (POSIX) /
SetUnhandledExceptionFilter (Windows) that flushes the in-memory ring to
a fixed crash_dump.log before the process dies.
This required reworking LogRing (step 3) to be genuinely lock-free, not
just mutex-protected: a signal handler that blocks on a lock the
crashing thread (or another thread) already holds turns a clean crash
into a hang -- no ring dump *and* no core dump, worse than doing
nothing. append() now claims a slot with a single atomic fetch-add;
dumpToFd() reads the preallocated entries directly and writes them with
write(2) only, looping on EINTR/short writes. Accepted tradeoff: at most
one entry can be read torn if a crash lands mid-append into that exact
slot -- documented in logring.h, and the alternative (a seqlock to
detect and retry) wasn't judged worth the complexity for that window.
Other invariants implemented per the discussion:
- sigaltstack with a static 64 KiB buffer, SA_ONSTACK -- a stack-
overflow SIGSEGV has no usable stack for a handler without one.
- Nothing under the actual handler touches Qt, QString or the
allocator: the dump path and a small header (version/git/OS/Qt) are
precomputed into fixed char buffers by install(), which runs once at
startup in normal context.
- Atomic test-and-set so only the first crash writes a dump; a second
concurrent/nested fault goes straight to restore-and-re-raise.
- After writing, the handler restores SIG_DFL and re-raises (POSIX) /
returns EXCEPTION_CONTINUE_SEARCH (Windows) so the OS's own crash
path -- core dump, Windows Error Reporting -- still runs. A handler
that "fixed" the crash by swallowing the signal would destroy exactly
the post-mortem evidence this whole design exists to preserve.
Tested in this environment: POSIX/Linux only, all five signals. Sent
each directly to a running process and confirmed (a) crash_dump.log is
written with the correct header and ring contents, mode 0600, and (b)
the process still terminates via the signal with the kernel's own
"core dumped" flag set (exit code 128+signal, confirmed for all five).
The Windows path is implemented per the discussion's guidance but is
untested -- no Windows build available in this sandbox.
## Step 5 -- getting the data back out
- QETApp::checkCrashDump(), called from checkBackupFiles() only when
there's no stale project file to recover this run (so the two
prompts never both show, per the discussion), offers an unretrieved
crash dump via DiagnosticsReportDialog and then deletes it regardless
of the user's choice -- offered exactly once.
- A new "Aide > Enregistrer un rapport de diagnostic..." action
(QETMainWindow) builds the same kind of report from the *current*
session (QetLogger::buildDiagnosticsReport(): header + this session's
log file) for a manual "attach this to a bug report" flow, not tied
to a crash.
- Both go through QetLogger::redact() before ever reaching the user:
the one redaction implemented is a literal replace of the home
directory with "~", since an absolute path under it leaks the
account name. The discussion's fancier "optionally redact project
filenames too" isn't attempted -- reliably telling a project path
apart from arbitrary log text is a much fuzzier problem than a
literal prefix match.
- DiagnosticsReportDialog shows the full (already-redacted) content
before saving, per the discussion: "the user is about to attach this
to a public tracker."
Verified in a real GUI session (Xvfb): triggered a SIGSEGV, relaunched,
confirmed the crash-report dialog appears with the right header/content,
confirmed it does not reappear on a second relaunch, and confirmed the
manual "Save report" action produces a correctly-formatted report and
saves it to a chosen path.
Built clean, no new warnings.
## Build systems
Registered in both: cmake/qet_compilation_vars.cmake, and
qelectrotech.pro. The .pro needed explicit globs for the new
sources/logging/ui/ subfolder -- sources/logging/*.{h,cpp} was already
globbed, but unlike the other ui/ subfolders that one had no entry of
its own, so diagnosticsreportdialog.{h,cpp} would not have been built
under qmake.
ProjectView::initWidgets() called insertSpacing(1, 10) on a QHBoxLayout
that was still empty, inserting past the end of the item list. The
corrupted layout crashed later in QWidget::setLayout() via
QLayoutPrivate::reparentChildWidgets() and QBoxLayout::itemAt().
Use addSpacing(10) instead, which is equivalent for an empty layout.
Never leave a collection folder without a name (replaces #622)
Mark elements-folder with an exclamation-mark, when "qet_directory" is missing or faulty.
The unconditional early return was narrowed to non-directories only, so
that the just-added warning badge could be picked up once setUpData()
resolved m_qet_directory_unreadable asynchronously. But every directory
then called setIcon() on every single data(Qt::DecorationRole) query --
not just once -- and QStandardItem::setIcon() -> setData() emits
dataChanged() unconditionally (QIcon has no equality check to suppress
it). QTreeView handles dataChanged() by recomputing the row's size hint,
which re-enters data() for the same index, calling setIcon() again:
unbounded mutual recursion, confirmed by an isolated reproduction to
overflow the stack in a single frame (100k+ frames) well before the
first paint completes. Matches plc-user's report of a segfault right as
the elements tree begins drawing.
The race the guard was widened for doesn't actually occur:
ElementsCollectionModel only attaches itself to the tree view (the only
way data() becomes reachable) from loadingFinished(), which fires after
the QtConcurrent::map over every item -- this one included -- has
already finished. m_qet_directory_unreadable is therefore always final
before setUpIcon() can run for the first time, so the plain, always-only-
once guard is sufficient and the badge still works correctly.
"Add folio" always appends to the end of the project, ignoring
whatever folio is currently selected in the left panel -- even though
the panel already tracks the selected diagram's position for its
existing move up/down/top actions, and QETProject::addNewDiagram(pos)
already accepts an arbitrary insertion index, pushed as an undoable
AddDiagramCommand (QetGraphicsTableFactory::create() already relies on
this exact mechanism to insert a folio right after a specific one).
Add two new context-menu actions that compute the target position from
the selected diagram's folioIndex() and pass it straight through the
existing machinery -- no changes needed to QETProject or
AddDiagramCommand. New requestForNewDiagramAt/addDiagramToProjectAt
signal/slot pair added alongside the existing
requestForNewDiagram/addDiagramToProject rather than changing it, so
the plain "Add folio" action's append-at-end behavior is untouched.
Drawing tools on the diagram canvas always started new shapes and free
text from a fixed hardcoded default (Qt's plain QPen()/QBrush(), and
the static Preferences font) -- changing a shape's color or a text's
font had zero effect on what the next new item of that type got, even
within the same editing session.
Add LastUsedStyle: a small in-memory, session-scoped static helper
(no QSettings, no persistence across restarts -- this is a live "what
did I just use" value, not a new app-wide default). Write side hooks
capture the value right where the properties editors already apply a
change (ShapeGraphicsItemPropertiesWidget::associatedUndo(), both the
live-edit dock path and the modal editProperty() dialog path; and
IndiTextPropertiesWidget::on_m_font_pb_clicked() right after the font
dialog returns). Read side hooks apply the stored value, if any, to a
newly created item: DiagramEventAddShape::mousePressEvent for shapes,
IndependentTextItem's constructor for free text (falling back to the
existing QETApp::indiTextsItemFont() Preferences default otherwise).
Doesn't touch the element/symbol editor's own drawing tools (a
separate subsystem) or add last-used text color (no color control
exists in the text properties UI to originate it from yet).
@plc-user asked (review on #633) for a way to see a broken folder
directly in the tree instead of only on tooltip hover, originally
suggesting a "FixMe: " text prefix on the displayed name. That name is
reused verbatim in dialog titles and status-bar messages elsewhere
(elementscollectionwidget.cpp), so baking a prefix into it would leak
into those too. An icon badge gets the same visibility without
touching the name value.
setUpIcon() overlays a small warning glyph on the folder icon when
m_qet_directory_unreadable is set. Also drop the "already has an icon,
skip" guard for directories specifically: that flag is only known once
the async setUpData()/localName() job completes (QtConcurrent::map), so
without this a directory painted before that finished would have its
plain folder icon cached forever and never pick up the badge.
Implements steps 1-3 of discussion #644 (deliberately not steps 4/5 --
no signal handler / crash flush, no diagnostics UI; see below).
## Step 1 -- fix the existing logger (bugs, no new behavior)
- One QFile handle held open for the whole session under a mutex,
instead of opening and closing the log file on every single message.
- The log directory and the session's date-stamped filename are
resolved exactly once, in the new QetLogger::init() called explicitly
from main() immediately before qInstallMessageHandler() -- not
recomputed per message, so a session that runs past midnight now
stays in one file instead of silently splitting.
- Age-based retention now uses lastModified() instead of lastRead():
opening a log to attach it to a bug report no longer resets its
retention clock.
- stderr and file output both encode UTF-8 explicitly (toUtf8()),
replacing stderr's toLocal8Bit() and the file stream's previously
Qt5/Qt6-inconsistent default encoding.
## Step 2 -- size-capped rotation + hardening
- The previously-unbounded daily file is now capped at 2 MiB and
rotated (kMaxFileBytes/kRotationKeep in QetLogger), keeping
<date>.log plus <date>.1.log .. <date>.4.log; oldest is dropped.
- Each message is truncated to 4 KB with a "...[truncated N bytes]"
marker before it reaches the ring or the file.
- Control characters (newlines, tabs, other non-printables) in message
content are escaped, since much of what QET logs is externally
controlled (file paths, element names, font strings out of a .qet
file) -- left unescaped, an embedded '\n' could forge log lines.
- The log file is refused if a symlink already exists at that path,
and is created/rotated owner-read/write only.
## Step 3 -- in-memory ring buffer
- LogRing (sources/logging/logring.h) is a fixed-capacity, always-on
ring of the last 4096 log lines, preallocated once at construction
(4096 * 512 B = 2 MiB) so append() never allocates. Entries are
stored as plain pre-formatted bytes in fixed-size slots -- the shape
discussion #644 specifies so a *future* crash handler could dump it
with nothing but write(2), even though no such handler exists yet.
Thread-safe via a plain QMutex (the lock-free requirement in the
discussion applies specifically to a signal-handler read path, which
this step doesn't add).
## Escape hatch
QET_LOG_DISABLE=1 in the environment at startup bypasses all of the
above -- no ring, no file, no rotation -- falling back to a minimal,
self-contained stderr passthrough that doesn't share any code with the
new formatting/sanitization path, so it stays usable even if that path
is what's misbehaving.
## Deliberately not included (per the discussion's own phasing)
- No signal handler / crash-time ring flush (step 4) -- the discussion
flags this as the highest-risk piece, explicitly meant to land last
and behind its own switch once the rest is proven.
- No diagnostics export UI (step 5).
- No log categories, session header, repeat collapsing or rate
limiting -- listed under "best practices worth building in", not
part of steps 1-3.
## Testing
Built clean, no new warnings.
Verified with real runs (QT_QPA_PLATFORM=offscreen, isolated HOME):
- Log file created at the expected dataDir()/YYYYMMDD.log path, mode
0600.
- A full startup's worth of real messages (translations, MachineInfo's
system dump, collection loading) written correctly; every one of the
231 lines in one run starts with a proper timestamp -- confirmed the
sanitizer correctly escapes the raw embedded newlines/tabs in
MachineInfo's multi-line CPU/GPU description fields into visible
\n/\t sequences rather than letting them fragment the log.
- QET_LOG_DISABLE=1: zero log files created, stderr still worked via
the independent legacy path.
- Rotation: pre-filled a log to just under the 2 MiB cap, ran a normal
session, confirmed it rotated to <date>.1.log (still 0600) with a
byte-clean split (no truncated/duplicated line at the boundary) and
a fresh <date>.log picked up from the next line.
Placing an auto-numbered element or conductor advances a shared
NumerotationContext counter (QETProject::addConductorAutoNum/
addElementAutoNum) as a side effect that sat entirely outside the undo
stack. Undoing the placement removed the visible number but left the
counter advanced, so every undo of an auto-numbered placement silently
burned a number, with no way to get it back short of a manual reset.
Adds SetAutoNumContextCommand, a small QUndoCommand storing the old/new
NumerotationContext and calling the matching add*AutoNum() setter on
undo()/redo() -- the same shape QPropertyUndoCommand already uses next
to it in ConductorAutoNumerotation::applyText().
Wires it into the two conductor call sites (the static newProperties(),
and numerateNewConductor(), both in ConductorAutoNumerotation) and the
element call site (Element::setUpFormula(), called from
DiagramEventAddElement::addElement() when a new element is dropped onto
a diagram). setUpFormula() now takes an optional parent QUndoCommand;
addElement() calls it before pushing its own undo_object so the counter
change lands in the same undo macro as the element's placement -- one
Ctrl+Z reverts both together, instead of leaving the counter adrift.
The project-properties config dialog's own add*AutoNum() calls (editing
the numbering rule itself, not a side effect of placing something) are
deliberately left untouched, as are the load-time folio-sequential
bookkeeping calls in Diagram::loadElmtFolioSeq()/loadCndFolioSeq() and
the bulk folio-renumbering passes in QETProject -- none of those run as
part of an undoable user gesture.
Implements the scope proposed in discussion #608.
ElementInfoWidget's fixed ~40 predefined ELMT_* keys had no way for a
user to add a genuinely new element-info key, even though DiagramContext
already stores/round-trips arbitrary keys generically via toXml()/fromXml().
Adds an "Ajouter une propriété personnalisée" button that appends a
CustomElementInfoPartWidget row (both key and value user-editable,
unlike the fixed ElementInfoPartWidget rows bound to one predefined
key). The typed key is validated live against the existing
DiagramContext::isKeyAcceptable() and flagged with a red border when
it doesn't match, instead of silently dropping it. Any key already
present on the element that isn't one of the predefined/special keys
is re-displayed as a custom row on next selection.
Implements the scope proposed in discussion #611.
Suggests the element's filename (without its .elmt extension) as the
default save name when exporting to SVG, instead of only defaulting to
the customElementsDir with no filename. Addresses plc-user's review
suggestion on PR #637.
Implements discussion #605. The diagram editor can already export a folio
to SVG; the element editor, where a single .elmt symbol is drawn, had no
export capability at all -- confirmed by grepping its header for "export"
before starting: nothing.
## Renders the live scene, not ElementPictureFactory's cache
The discussion proposed sourcing this from ElementPictureFactory's cached
per-element QPicture (m_pictures_H), the one used for the elements-panel
preview icons. Checked that cache's actual invalidation before building on
it: nothing in the editor ever tells it to drop an entry on edit, and it is
keyed by the element's on-disk uuid. So for any element already previewed
once in the panel, exporting from the cache would silently produce stale
content after any edit; for a brand-new, never-saved element, no entry
would exist at all. Neither is acceptable for a File > Export action a
user expects to reflect what's on screen right now.
Renders ElementScene directly instead, the same way
ExportDialog::generateSvg() already renders the live Diagram for the
diagram editor's own SVG export: no new drawing logic, only a new playback
target (QSvgGenerator instead of the screen), sized to the element's own
content bounds via the existing elementSceneGeometricRect() helper.
## Hotspot cross excluded from the export
ElementScene::drawForeground() draws the red origin/hotspot cross on every
render() call, unconditionally -- it's an editing aid, not part of the
element being drawn, and diagram editor's SVG export has no equivalent
problem since Diagram doesn't draw one. Added a settable
hotspotVisible flag, defaulting to true (the existing editing view is
completely unaffected) and turned off only for the duration of the export
render() call.
## Verified end-to-end via a real Xvfb session, not just a build
Opened a real shipped element (en_60617_05_06_04.elmt, "Phototransistor"),
exported it, and rendered the resulting SVG back to a bitmap with a small
QSvgRenderer-based harness -- pixel-identical in shape to the element as
shown in the editor. Confirmed the file is valid XML and contains no
red/#ff0000 stroke (the hotspot cross did not leak in).
Then the case the whole "render live, not cached" decision was about:
opened the same element, drew a new line with the line tool, and exported
again *without saving*. The new line is present in the exported SVG.
git status on the source .elmt file after both exports shows it completely
untouched -- the export is read-only and reflects live, unsaved editor
state, exactly the property a cache-based implementation would have gotten
wrong.
Built clean, no new warnings.
Reported by @scorpio810 on #626: "The field does not update automatically;
you need to list the other rules for it to update."
Two reasons, both mine:
The refresh was wired to the combo boxes' activated() signal, which Qt
emits only for user interaction. Nothing that changed a context
programmatically -- which is to say, numbering an element -- ever reached
it. Re-picking a rule from the combo was not a workaround so much as the
only code path that refreshed at all.
And there was no signal to hang it on for two of the three categories:
addElementAutoNum() emitted elementAutoNumAdded(), but addConductorAutoNum()
and addFolioAutoNum() emitted nothing, so even a listener would not have
heard a conductor counter advance.
Add QETProject::autoNumContextUpdated(), emitted by all three setters, and
have the dock re-read its three fields on it. Kept deliberately separate
from the existing *AutoNumAdded/*Removed signals: those make listeners
rebuild their rule lists, which is both heavier than needed here and would
disturb the user's current selection every time an element is numbered.
This one only says "re-read me".
The automatic refresh skips a field that has keyboard focus, so numbering
an element cannot overwrite a value half-typed under the cursor. Explicit
refreshes after a reset or an edit still write unconditionally, so the
field always ends up showing the canonical stored value.
Measured, advancing a counter the way numbering advances it and without
touching the combo box:
field before advance "5"
context after advance 6
field after advance "6" (was still "5")
