When an item type is selected for the first time the properties dock
expands, causing the QGraphicsView viewport to shrink. Qt recalculates
scene coordinates and fires one or more synthetic mouseMoveEvents before
the user has actually moved the mouse.
The original code used a single-shot m_first_move flag in
CustomElementGraphicPart, which absorbed exactly one spurious event.
PartText and PartDynamicTextField had no protection at all.
Fix: compare screen-coordinate displacement against
QApplication::startDragDistance() (~4 px). Screen coordinates are
stable across viewport resizes, so the check correctly rejects
synthetic dock-expansion events while allowing genuine drags.

Same root cause as ProjectPropertiesDialog: Qt::WindowModal only blocks the
direct parent window, leaving the rest of the MDI area live. If new_project
or close_project fires while the app settings dialog is open, any raw pointers
derived from the project list become stale. Switch to ApplicationModal to
block all windows for the duration of the dialog.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
ProjectPropertiesDialog::exec() was using Qt::WindowModal, which only
blocks the parent ProjectView window. The MDI workspace and its other
subwindows remained interactive, so actions like new_project or
close_project could fire while the dialog's config pages still held raw
QETProject* pointers — leading to a SIGSEGV when Qt's event loop later
dispatched a signal through one of those stale pointers.
Detected by the 8-hour GUI fuzzer: action sequence add_diagram_page →
flood_wires ×18 → new_project while Project Properties was open
produced exit code -11 (SIGSEGV) on the first of 12,717 actions.
Switch to Qt::ApplicationModal so no window can receive input while the
dialog is open. Project Properties is a short-lived dialog; blocking
the whole application for its duration matches user expectation and
removes the lifetime hazard without requiring QPointer surgery across
four config-page classes.

Follow-up to the eventFilter fix: testing showed double-click works
when QET is already running, but a cold launch (app not running yet)
still opens an empty window. Finder/Launch Services can deliver the
QFileOpenEvent to the QApplication's native event loop before main()
reaches the point where QETApp is constructed and its real eventFilter
is installed -- there's a window between 'SingleApplication app(...)'
and 'QETApp qetapp;' during which the event can arrive and be lost.
Add a minimal EarlyFileOpenCatcher installed on app immediately after
it's constructed (before anything else can run an event loop). It only
buffers the file path. Once QETApp exists, main() swaps it out for the
real QETApp::eventFilter and drains anything that was buffered via
qetapp.openFiles(), so no cold-launch QFileOpenEvent is silently
dropped.
Confirmed by manual testing:
- 'open app --args file' on .qet/.elmt/.titleblock: OK (already worked)
- double-click while app already running: OK (already worked)
- double-click cold launch: previously opened an empty window, this
buffers and replays the event so it now opens the right editor.
Root cause (see issue #218 discussion):
- QETApp::eventFiltrer (Q_OS_DARWIN) was correct in intent but never
actually installed as an event filter anywhere, and its name didn't
match the QObject::eventFilter virtual signature, so even if it had
been installed it would never have been invoked as an override.
Confirmed dead code.
- main.cpp instead routed Finder's QFileOpenEvent through
MacOSXOpenEvent -> SingleApplication::sendMessage(), which is the
secondary-to-primary IPC channel. Called from within the primary
instance itself, sendMessage() fails silently and the file path is
dropped, which is exactly what double-click does (Finder doesn't spawn
a secondary process, the running instance receives the FileOpen event
directly).
- openFiles() takes a QETArguments, not a QStringList. The dead code's
openFiles(QStringList() << filename) only worked via an untested
implicit QStringList -> QList<QString> -> QETArguments conversion
chain.
Fix:
- Rename eventFiltrer -> eventFilter (qetapp.h/.cpp) so it's a proper
override of QObject::eventFilter, and make it public so main.cpp can
install it on QApplication.
- Build the QETArguments explicitly instead of relying on implicit
conversion.
- main.cpp: drop MacOSXOpenEvent entirely (include + instantiation),
install qetapp as the Q_OS_MACOS event filter on app right after
QETApp qetapp; is constructed and before app.exec(). No race window:
the event loop hasn't started, so no QFileOpenEvent can be delivered
before the filter is installed.
QETArguments::handleFileArgument() already sorts files by extension
(.elmt, titleblock, else project) and openFiles() already fans out to
openProjectFiles()/openElementFiles()/openTitleBlockTemplateFiles()
accordingly, so this single fix covers .qet, .elmt and .titleblock
double-click/drag-to-dock on macOS, not just .qet.
SingleApplication's sendMessage/receivedMessage flow (used for CLI args
on all platforms) is untouched; this only touches the Q_OS_MACOS block,
so there is no behavior change on Windows/Linux.
Follow-up (not included here): the macOS Info.plist (misc/Info.plist)
has an empty CFBundleShortVersionString, which may affect macOS's
willingness to retain file associations across app updates.
pugi::xml_document::load_file(const char*) calls fopen/fopen_s on Windows,
which uses the ANSI codepage — not UTF-8. This silently fails when the
collection path contains accented characters (é, ü, ñ, …) or is longer
than the narrow-API MAX_PATH limit, leaving the collection panel with no
element names or illustrations.
Switch both call sites to toStdWString().c_str() which invokes the
load_file(const wchar_t*) overload. On Windows pugixml calls _wfopen,
the wide Unicode API that handles all valid Unicode paths. On Linux/macOS
the same overload converts wchar_t to UTF-8 internally and calls fopen,
so behaviour is unchanged on those platforms.
Affected files:
sources/ElementsCollection/fileelementcollectionitem.cpp (qet_directory load)
sources/ElementsCollection/elementslocation.cpp (element .elmt load, both branches)

- Resolve cmake/qet_compilation_vars.cmake conflict: keep both upstream's
cli_export.cpp/h and pdf_links.cpp/h and the EDZ source additions.
- 10-position grid alignment: pin_y values are multiples of 10 so terminals
snap cleanly to QET's default grid. group_gap raised to 10 (one full slot).
- Named connector groups get a header label (group name) placed in the gap
above the first pin, so the electrician sees block names (XDI, XPOW, …)
without reading individual terminal designations.
- Device-tag dynamic_text now uses 9pt LABEL_FONT and y = min_y - 9 so it
clears the element body and is legible at normal zoom.
- Add EPLAN Data Portal Terms of Use disclaimer to sources/import/edz/README.md.

saveConfig() serialises Qt::AlignHCenter as the string "AlignHCenter"
via QMetaEnum::valueToKey(), but loadConfig() matched against
Qt::AlignCenter (0x0084 = AlignHCenter|AlignVCenter) instead of
Qt::AlignHCenter (0x0004). The two values differ, so the switch fell
through to the default (Right) every time center was saved and reloaded.
Add Qt::AlignHCenter as the primary case and keep Qt::AlignCenter as a
fallthrough for any config files that were hand-edited by users following
the workaround documented in issue #283.
Verified with a standalone Qt test: QMetaEnum::keyToValue("AlignHCenter")
returns 4 (AlignHCenter), which now correctly resolves to combobox index 1
(Center) instead of 2 (Right).

The default user-collection path ends in "elements" and the default
company-collection path ends in "elements-company". Both
FileElementCollectionItem::isCustomCollection() and
ElementsLocation::isCustomCollection() used startsWith(customDir),
so "…/elements-company/…" matched "…/elements" and returned true.
This caused ElementsCollectionModel::addLocation() to insert a
newly-saved user-collection element as a child of the company-
collection branch in the tree, making it appear in the wrong panel.
Fix: require the path to equal the directory root exactly, or to
start with the directory root followed by '/'.
path == dir || path.startsWith(dir + QLatin1Char('/'))

Previous logic resolved duplicate connectionDesignation values by
appending sanitised description text or numeric suffixes, which was
fragile and produced names an electrician could not easily map back to
the physical wiring.
New scheme:
• terminalNr present → "XDI.2", "XRO1.3", "XPOW.1" …
• terminalNr absent → designation as-is ("L1/U1", "UDC+", "PE") —
these are busbar / power connections and are already globally unique
• collision (malformed data) → numeric suffix as safety net
The description (connectiondescription) remains as the human-readable
label beside the terminal symbol, exactly as suggested by plc-user.

EdzPin gained a third field (group) but the fallback initializer at
line 70 still listed only two fields, triggering -Wmissing-field-initializers.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
EPLAN 2022-style part.xml files (e.g. IFM AL1122) use a numeric
functiondefgroup attribute and do not carry the text functiondefinition
block name that the previous grouping logic relied on. Those parts
fell back to grouping by pin designation, producing symbols with all
pin "1"s stacked together, then all "2"s, etc. — the bug reported in
PR #513.
Fix: read terminalNr first (the physical M12/connector socket identifier,
e.g. "X01", "X31") as the primary group key; fall back to functiondefinition
text for older EPLAN formats that omit terminalNr. Pins within each
connector group are still sorted by designation using natural sort.
Also remove the dashed inter-group separator lines; the existing 5 px
gap between groups provides sufficient visual separation.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The previous grouping compared `connectionDesignation` values (e.g. "1",
"2", "3") to detect group boundaries. Those values are pin position
numbers within a terminal block, not functional group identifiers, so
devices like the ABB ACS880 produced 11+ tiny single-pin "groups" instead
of the ~8 functional blocks (AC-IN, Motor-OUT, DC-Bus, Brake-Resistor,
Analog-I/O, Digital-I/O, ...) the reviewer identified.
Fix:
- Add `group` field to EdzPin, populated from the `functiondefinition`
attribute on <functiontemplate> (newer EPLAN) or its parent <function>
element (older EPLAN).
- Sort pins by group first (preserving XML appearance order per group),
then by designation within each group using natural sort.
- Use `groupKey()` — group when present, designation as fallback — for
the group-break detection that drives separator lines and Y-gaps.
Parts without any functiondefinition data retain the previous
designation-based behaviour unchanged.

- StyleEditor: QGridLayout(this) pre-empted the widget's layout slot,
causing setLayout(main_layout) to silently fail and orphan main_layout.
Fix: use QGridLayout() without a parent so setLayout() succeeds.
- ExportDialog: ~ExportDialog() was empty, leaving ExportDiagramLine
heap objects in diagram_lines_ unfreed. Fix: qDeleteAll(diagram_lines_).
- GenericPanel::getItemForDiagram: when called without the bool* created
arg, it created a parentless QTreeWidgetItem that callers immediately
discarded. Fix: return nullptr when created==nullptr and item not found
(all callers already guard with if (item)).
- ElementScene: m_paste_area (created in initPasteArea) was temporarily
added/removed from the scene during XML loading but never freed in the
destructor. Fix: delete it if not currently in the scene.

Qt 5.15.x added libxcb-cursor0 as a hard runtime dependency of the xcb
platform plugin (libqxcb.so). The kf5-5-110-qt-5-15-11-core22 content
snap does not bundle this library, so when the snap runs on an Ubuntu 24.04
host the dlopen() of the plugin fails with:
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in ""
even though it was found.
Staging libxcb-cursor0 from the Ubuntu 22.04 archive satisfies the
dependency without changing the snap base, Qt version, or any other
dependency. No ABI mismatch: the plugin and the staged library are
both built against the core22 (22.04) ABI.
Fixes issue #373.

Pins are already sorted by designation (see EdzPart::parse natural sort).
This change makes same-designation groups visually obvious in the element
symbol by:
- Inserting a 5 px gap between consecutive terminals whose designation
differs, so each group reads as a distinct block.
- Drawing a thin dashed horizontal line through each gap, mirroring
the grouped-I/O style shown in typical manufacturer datasheets.
The body rectangle and bounding box grow automatically to accommodate the
extra gaps, so no fixed sizes change. Unique terminal names (added in the
previous commit) are unaffected.

Two issues raised in PR review:
1. Copyright year: new files carried "2006" (the project's founding year).
Updated to "2006-2026" to reflect the actual authorship period.
2. Duplicate terminal names: EPLAN parts can have multiple connection
templates sharing the same connectionDesignation (e.g. a drive where
both wire entries of terminal "1" are labelled "1"). QET requires
unique terminal names for wiring and terminal-diagram generation.
Resolution order in EdzElementBuilder::build():
- Unique designation → used as-is.
- Duplicated designation with distinct sanitised description →
"designation_description" (e.g. "1_L_P").
- Otherwise → numeric suffix: "1", "1_2", "1_3", …

1. machine_info.h: zero-initialise Screen struct members
Max_width, Max_height, count, width[] and height[] were bare
int32_t with no initialiser. The comparisons in
init_get_Screen_info() read them before any write, producing
undefined behaviour flagged by Valgrind as 'Conditional jump
or move depends on uninitialised value(s)'.
2. main.cpp: pre-initialise MachineInfo on the main thread
MachineInfo::instance() was first called inside QtConcurrent::run(),
causing its constructor (which calls qApp->screens()) to run on a
background thread. QScreen methods are not thread-safe in Qt5.
Calling instance() once on the main thread before the worker
launches guarantees the singleton is fully built first; subsequent
calls from the worker just return the cached pointer.
3. qetdiagrameditor.h: move m_first_show before the QActionGroup members
C++ initialises members in declaration order. m_first_show was
declared after the QActionGroup members (line 256 vs 168). During
construction of m_row_column_actions_group(this), Qt dispatches a
QObject parent-change event that reaches QETDiagramEditor::event(),
which reads m_first_show before it has been initialised.
Moving the declaration to the top of the first private: block
ensures it is initialised before any member that can trigger events.
All three found via Valgrind --tool=memcheck on Ubuntu 22.04 / Qt 5.15.3.
Relates-to: PR #514 (same QtConcurrent thread-safety pattern).
Reviewer requested configdir/datadir instead of cached for consistency
with the surrounding code style.

QStandardPaths::writableLocation() is not thread-safe in Qt5.
ElementsCollectionModel::reload() launches:
QtConcurrent::map(m_items_list_to_setUp, setUpData)
Each worker calls FileElementCollectionItem::setUpData()
→ collectionPath() → isCollectionRoot()
→ QETApp::userMacrosDir() → QETApp::dataDir()
→ QStandardPaths::writableLocation() ← SIGSEGV (null deref)
The crash was confirmed by Valgrind (address 0x0, inside
libQt5Core's writableLocation internals).
Fix: replace the bare QStandardPaths calls in dataDir() and
configDir() with a C++11 static-local lambda. The compiler
guarantees the lambda body runs exactly once across all threads
(magic statics, ISO C++11 §6.7). After the first (main-thread)
call the result is returned lock-free.
Relates-to: #492 (same QtConcurrent lifetime pattern fixed in
QETProject::writeBackup by PR #512).
- EdzArchive checks the archive magic up front: gives a clear message for
zip-format .edz (not yet supported) and unrecognised data, instead of an

- Trim the vendored LZMA SDK headers to the decode closure actually used
(removes 21 unused encoder/multithread/Xz/Aes headers; 18 .c + 18 .h remain).
- Add sources/import/edz/README.md documenting the feature, the data mapping

The new import action and dialogs used French source strings (QET convention)
but had no English translation, so they showed French in the English UI. Add

Replaces the QProcess->7z shim with the public-domain LZMA SDK (23.01) 7-Zip
reader, vendored under sources/import/edz/lzma/ (decode-only subset). New
edzsevenzip.cpp wraps SzArEx_Open/SzArEx_Extract and writes entries via Qt, so
EdzArchive no longer needs an external 7-Zip at runtime. Enables the C language
in CMake for the vendored sources.
Verified: the bundled decoder extracts all three ifm sample .edz and the
generated elements still match the Python oracle exactly (byte-correct decode),
with no 7z on the path.

Wires EPLAN .edz import into the elements panel. EdzImporter orchestrates
EdzArchive -> EdzPart -> EdzElementBuilder and writes the generated .elmt into a
destination collection folder (named by order number). A right-click
"Importer une piece EPLAN (.edz)..." action on a writable collection directory
opens a file picker, runs the importer into that folder's fileSystemPath() and
reloads the panel; errors surface via QetMessageBox. Modeled on newElement().
EdzImporter verified headless against the Python oracle for KG6000/MFH200/
R1D200; the panel wiring is built/tested via the WSL Qt5+KF5 build.

Port of the edz2qet.py prototype's mapping to C++. EdzPart parses an EPLAN
part.xml into a portable model (identity/metadata, localized names, connection
list); EdzElementBuilder turns that into a QET element (generic symbol: body
rectangle + one west-facing terminal per pin, per-pin labels, localized <name>s,
and elementInformations for the BOM).
Pins are natural-sorted by designation so they stack 1,2,3,4 regardless of the
order EPLAN lists them (MFH200 lists 1,3,4,2). Output verified structurally
identical (uuids aside) to the Python oracle for three ifm samples — KG6000
(4-pin), MFH200 (4-pin, reordered) and R1D200 (5-pin, incl. Dutch name) — and
the generated element loads in the QET editor with correct UTF-8.

First piece of native EPLAN Data Portal (.edz) import. A .edz is a 7-Zip
archive; QET previously had no archive handling. EdzArchive unpacks one to a
temporary directory and locates the contained part.xml.
The extraction backend is isolated behind extractWithSevenZipCli() so it can be
replaced with a bundled decompressor later without touching callers; this M0
step shells out to a 7-Zip CLI via QProcess. Verified on three ifm sample
parts (KG6000, MFH200, R1D200 — all 7z), plus the corrupt/missing-file paths.

Although I haven’t encountered the problems described myself (nor do I need to!), the changes and additions look plausible and compile without errors or warnings, so I’m approving this PR!
But as a remark:
I'm not particularly familiar with the Qt functions used here. But when I see that there is a version-specific implementation for Qt5 and only a debug-message mentioned for Qt6, it makes me wonder:
Is it implemented differently there, or is it not even needed there — which I don't think is the case...
If possible, "we" should also include something for Qt6 and later versions in another PR.
Do you know what’s needed for Qt6, @ispyisail ?
writeBackup() fires QtConcurrent::run(QET::writeToFile, ..., &m_backup_file)
fire-and-forget: the QFuture was discarded and nothing kept m_backup_file
alive until the worker finished. If the QETProject was destroyed first, the
worker wrote through the freed member -> use-after-free crash in
QET::writeToFile (intermittent; ~1/6 on short-lived CLI runs).
Store the QFuture and waitForFinished() in ~QETProject (and before
setFilePath() re-points the managed backup file). Also skip launching a new
backup while one is still running, so two threads never write m_backup_file
at once.
The Qt6 path is still a TODO stub and the QtConcurrent block is KF5-only, so
this affects only the Qt5/KF5 build that actually has the backup code.
Per review (plc-user): scope the reset to items currently painted with the
red Dense4Pattern instead of clearing every item's background. This avoids
clobbering other backgrounds (e.g. the amber "show this dir" highlight)
and skips needless item updates on large collections.
ElementsCollectionModel::highlightUnusedElement() only ever painted the
currently-unused elements red; it never cleared the background of items
that were no longer unused. So when an element was re-added to a project
and saved, its red 'unused' highlight persisted until the model was
rebuilt from scratch.
Reset every item's background before re-applying the highlight to the
current unused set.
