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)

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('/'))

- 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.

Terminal stores its TerminalData* as member d but never deletes it.
Every Element creation (placing on diagram, loading icon for the
element browser, drag previews) leaks one TerminalData per terminal.
ASan confirmed 112 leaked objects (9856 bytes) in a short session
across four call sites all rooted in Element::parseTerminal.

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.

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).
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.
The Windows search list for the qet_tb_generator plugin included
`~/Application Data/qet/qet_tb_generator.exe` as a fallback. That legacy
junction path is the same inaccessible location the standard-directories
change moved QET away from, and it never matched a pip install anyway:
`pip install qet_tb_generator` puts the executable in the Python Scripts
directory (`...\PythonXX\Scripts` on PATH, or
`%APPDATA%\Python\PythonXX\Scripts` for --user installs), not in
`QETApp::dataDir()`.
Pip installs are already found via QStandardPaths::findExecutable (PATH),
and manual binary drops via dataDir()/binary and the working directory.
The legacy entry only matched old manual drops into the inaccessible
folder, so remove it.

Without a source-tag or source-commit, snapcraft pulls the latest
HEAD of qet_tb_generator-plugin on every build. This makes builds
non-reproducible and risks breakage whenever the upstream repo changes.
Pin to the only published release tag (v1.31, commit d6ee3cf) so
the snap always builds against a known-good version of the plugin.
Closes#202

The .desktop, MIME package, and appdata install rules are
freedesktop.org conventions and only apply on Linux. Wrapping
them in if(UNIX AND NOT APPLE) prevents a configure failure on
macOS and Windows where QET_APPDATA_PATH and QET_MIME_PACKAGE_PATH
are not defined.
Also replace the hardcoded share/mime/packages path with
${QET_MIME_PACKAGE_PATH} for consistency with
paths_compilation_installation.cmake.
No change to Linux build behaviour.
