Follow-up to #740, which fixed the slave-side "(n-Xn)" cross-reference
label. The master-side item - the small table/cross drawn next to a
report or master element, listing where each of its slaves is used -
was still missing from DXF export. Measured against examples/
industrial.qet with the PDF export as an oracle (renders the whole
scene, so it shows what should be there):
before after PDF
slave xrefs "(n-Xn)" 41 41 41 (already fixed, #740)
folio/position strings 358 403 403
DXF now matches the PDF exactly.
## Why this needed a different approach than #740
The slave label is a plain QGraphicsTextItem - one string, trivial to
walk and re-emit as a single DXF TEXT entity, which is what #740 did.
The master-side item (CrossRefItem) is not: it paints itself with
~600 lines of hand-written QPainter calls across three modes
(drawAsCross/drawAsContacts/drawAsPlcTable), including a header
table, contact symbols, and rules. Hand-porting that logic to emit
DXF primitives directly would mean maintaining two divergent
implementations of the same drawing that have to be kept in sync by
hand forever.
## Approach: a QPaintEngine that intercepts CrossRefItem's own paint()
DxfPaintEngine/DxfPaintDevice (sources/dxfpaintdevice.{h,cpp}) is a
QPaintEngine/QPaintDevice pair - the same mechanism QPrinter and
QSvgGenerator use to redirect QPainter output elsewhere. Constructing
a QPainter on a DxfPaintDevice and calling item->paint() on it produces
DXF entities instead of pixels, using the exact same drawing code that
already renders correctly on screen. CrossRefItem::paint() is
unmodified.
Scope is deliberately narrow - only the QPainter calls CrossRefItem's
paint() is observed to make: drawLines -> LINE, drawRects/drawPath's
fill case -> outline-only LWPOLYLINE (no HATCH support in v1 - DXF's
fill primitive is a separate, more involved entity type; documented as
a known limitation rather than attempted here), drawEllipse -> CIRCLE
or a flattened polygon for rotated ellipses, drawPath's arc case (from
drawArc/drawPie) -> chord-flattened LINE segments, drawPolygon ->
LWPOLYLINE, drawTextItem -> TEXT. drawPixmap is intentionally
unimplemented (qWarning + skip) since CrossRefItem never calls it -
this is not a general-purpose DXF paint engine, and isn't meant to be
in this PR.
CrossRefItem::paint() is protected, per the normal QGraphicsItem
contract - added a small paintForExport() wrapper rather than making
paint() itself public, or reaching around access control.
## Explicitly out of scope
QetShapeItem::toDXF() and QetGraphicsTableItem::toDXF() (both already
implemented and working) are untouched. Rewriting working exporters
onto this engine to prove an architectural point would be a large,
unrelated diff with no user-visible benefit - if that consolidation is
wanted later, it's a separate proposal once this engine has shipped
and proven out on the one item that currently has no DXF export at
all.
## Testing
Built clean on Qt5/Linux. Verified via the GUI export dialog
(Fichier > Exporter > DXF) against examples/industrial.qet, 50 folios:
export completes without error or crash, all 50 .dxf files are
structurally well-formed (balanced SECTION/ENDSEC, single EOF each),
and grepping the folio-position pattern gives the before/after/PDF
numbers above. Spot-checked several real label strings (e.g. "18-B18",
"20-A2") present as TEXT entity values in the output, not just an
artifact of the count matching.
- build-windows-qt6: install kwidgetsaddons/kcoreaddons/extra-cmake-modules,
switch -DBUILD_WITH_KF=OFF to ON, add -DBUILD_KF=OFF to use precompiled
MSYS2 packages instead of building KF6 from source via FetchContent
- build-windows: swap unsuffixed kwidgetsaddons/kcoreaddons (actually KF6
packages after MSYS2's renaming) for the -qt5 suffixed ones, add
-DBUILD_KF=OFF so the installed packages are actually consumed instead
of being ignored by the default FetchContent-from-source build

## Bug
Element library icons (collection tree thumbnails, drag icon, preview
panels) render with a fully transparent background. Element definitions
almost always hardcode a black stroke color, on the assumption of the
white diagram sheet they are normally drawn on. Against a dark widget/
tree-view background (e.g. KDE Plasma dark theme), that black stroke
disappears entirely - reported as icons being "black and almost
invisible". scorpio810_mantis linked this to the same recurring family
as #231, #247, #267.
## Fix
ElementPictureFactory::pixmap() is the single shared point where every
consumer of these icons gets its QPixmap (collection tree via
ElementsCollectionCache -> Element::pixmap(), master/slave properties
tree, element properties preview, drag icon). Change its background
fill from fully transparent to opaque white - exactly what the element
already visually assumes in every context this pixmap is used, so it
is correct regardless of the surrounding widget's palette.
## Testing
Built both variants and compared under Xvfb using a simple, decisive
visual test: select the tree row (giving it a highlighted/colored
background) and compare what shows immediately around the icon's
glyph.
- Before: the icon's background matches the row's selection color -
confirms it is transparent, so on a dark unselected row the black
strokes would have the same problem.
- After: a solid white square is visible behind the glyph regardless
of the row's background color.
Note for the on-disk pixmap cache used by ElementsCollectionCache
(~/.local/share/QElectroTech/QElectroTech/elements_cache.sqlite):
existing cached PNGs predate this fix and will keep their transparent
background until regenerated. That cache already keys strictly on
path+uuid with no invalidation on QET version, so this is an existing
characteristic of that cache, not something introduced here.
Bugtracker #291: clicking Cancel on the open/save-element dialog before
the user collection finishes loading crashes the whole application with
an unhandled pointer exception.
ElementsCollectionModel::loadCollections() loads collections in the
background via QtConcurrent::map(m_items_list_to_setUp, setUpData) -
worker threads call setUpData() on each ElementCollectionItem
(a QStandardItem), which does setFlags()/setData() on it.
ElementDialog::execConfiguredDialog() deletes the dialog immediately
after exec() returns:
element_dialog->exec();
...
delete element_dialog;
That destroys the tree view and its ElementsCollectionModel, which as
a QStandardItemModel frees all its items in its destructor. Nothing
waited for the QtConcurrent::map() to finish first, so on Cancel before
loading completes, background threads were still calling setUpData()
on items the main thread had just freed - a use-after-free race.
Add an ElementsCollectionModel destructor that waits for the future
before QStandardItemModel's destructor runs. QFuture::waitForFinished()
on a default-constructed (never-started) future returns immediately, so
this is a no-op whenever loading already completed - the crash path is
the only one affected.

Cross-references were missing from DXF exports, as reported on the
forum: https://qelectrotech.org/forum/viewtopic.php?id=2481
generateDxf() walks the scene and collects items by cast. A slave
element's cross-reference label ("(6-G15)", pointing back to its master)
is a plain QGraphicsTextItem hung off a DynamicElementTextItem as a
child, so it matches neither the IndependentTextItem nor the
DynamicElementTextItem branch and was dropped on the floor. Nothing was
wrong with the label itself; it was simply never collected.
Collect it through the existing DynamicElementTextItem::slaveXrefItem()
accessor and draw it with the same placement, rotation and multi-line
handling as the other text items, using defaultTextColor() since a bare
QGraphicsTextItem has no DiagramTextItem::color().
Measured on examples/industrial.qet, comparing against the PDF export
(which renders the whole scene and so shows everything):
before after PDF
slave xrefs "(n-Xn)" 0 41 41
folio/position strings 317 358 403
The slave cross-references now match the PDF exactly.
Still missing, and not addressed here: the master-side cross-reference
table drawn by CrossRefItem, which accounts for the remaining 45
strings. CrossRefItem is a QGraphicsObject that renders itself with
custom QPainter code in three different modes (drawAsCross,
drawAsContacts, drawAsPlcTable) including contact symbols and rules, so
giving it a DXF representation is a larger piece of work than this.
"exclude_from_bom" is listed in QETInformation::elementInfoKeys() so the
project database can build the element_info table column for it, but it
is not a free-text property: ElementInfoWidget already gives it its own
"Exclure de la nomenclature" check box.
Because buildInterface() creates one ElementInfoPartWidget per key in
that list, the key also got a second, generic edit row. And since
translatedInfoKey() has no case for it and falls through to
"return QString()", that row carries no label at all - an anonymous edit
line at the bottom of the panel. currentInfo() then writes
exclude_from_bom unconditionally, so as soon as the user edits anything
the nameless row fills with "true"/"false".
Drop the key from the list buildInterface() iterates. The check box
remains the only way to set it, currentInfo() still writes it exactly as
before, elementInfoKeys() is untouched so the database schema and
elementquerywidget are unaffected, and predefinedKeys() already excluded
it from the custom-property rows.

QVector<int>(Qt::DisplayRole) creates a vector of size 0 (since Qt::DisplayRole == 0), not a vector containing DisplayRole. Fixed

The sam applies to QVector<int>(role) which gets changed to {role}.
<private/qpdf_p.h> (QPdfEngine::drawHyperlink) needs Qt's private GUI
module, previously flagged only by a #warning at compile time.
Qt >= 6.7 ships GuiPrivate as a proper find_package component, but some
distro packages (e.g. Ubuntu's qt6-base-private-dev, Qt 6.8.3) do not
install Qt6GuiPrivateConfig.cmake and only provide the implicit
Qt6::GuiPrivate target created alongside Qt6::Gui. Requesting the
component unconditionally would therefore break distro-Qt builds.
Instead: try the component quietly, then hard-verify the Qt6::GuiPrivate
target exists after the main find_package, failing at configure time
with an actionable message if the private headers are missing. The
compile-time #warning in pdf_links.cpp and projectprintwindow.cpp is
now redundant and removed.
Verified: cmake configure + compile of both translation units on
Ubuntu 25.04 / Qt 6.8.3 (system KF6), cmake configure on Qt 5.15.

Selecting more than one dynamic text field in the element editor silently
replaced every selected field's colour with the colour of the first one.
Nothing was clicked -- merely extending the selection destroyed the others'
colours, and the change went onto the undo stack as if the user had asked
for it.
Cause: updateForm() loads the current part's colour into the colour button
with m_color_kpb->setColor(). KColorButton::changed is emitted for a
programmatic setColor() just as it is for user interaction, and it is
connected to m_color_kpb_changed(), which applies the new colour to *every*
part in m_parts. So simply displaying the first part's colour wrote that
colour to all the others.
Every other widget in updateForm() is immune because it is wired to a
user-only signal -- on_m_x_sb_editingFinished(), on_m_frame_cb_clicked() --
which setValue() and setChecked() do not emit. The colour button is the one
control whose signal cannot distinguish the two, so block it while loading.
This also explains why the reporter saw it only when rubber-band selecting
bottom-to-top: the write happens only when the first part's colour differs
from what the button already shows, which depends on selection order.
Verified in the element editor with two dynamic texts, one red and one blue:
select the red one, then ctrl-click the blue one. Before: the blue text
turned red. After: both keep their colours. Changing the colour deliberately
with the button still applies to all selected texts, as intended.
Forum report (qelectrotech.org/forum, topic 3005, reporter oc67): a
project named e.g. "Mon_projet.avec_un_point.qet" exported to PDF as
"Mon_projet.pdf" - everything after the first "." in the filename was
silently dropped.
Root cause: ProjectPrintWindow::docName() used QFileInfo::baseName(),
which returns the filename up to the FIRST "." rather than stripping
only the final suffix. docName() feeds both the PDF print job's
setOutputFileName() and the QFileDialog::getSaveFileName default in
exportToPDF(), so the truncation showed up as the actual exported
file's name, not just a dialog suggestion.
sources/exportdialog.cpp's SVG/PNG/DXF export path already uses the
correct QFileInfo::completeBaseName() (strips only the last suffix) -
this fix brings the PDF/print path in line with that existing,
correct pattern rather than introducing a new approach.
Verified the exact before/after behavior with a standalone QFileInfo
test: baseName() on "Mon_projet.avec_un_point.qet" returns
"Mon_projet" (the bug); completeBaseName() returns
"Mon_projet.avec_un_point" (correct). Also did a clean incremental
build with no new warnings/errors.

Fix bugtracker #251: title block template with slash in name fails silently
There are some characters that are not allowed in filenames.
Absolutely correct to mark a filename containing (one of) them as invalid!
Saving a new user title block template (right-click "Cartouches
utilisateur" > "Nouveau modèle" > "Enregistrer sous") with a name
containing a slash (or other filesystem-reserved character) silently
did nothing, with no error shown. The entered name is turned directly
into a filename (TitleBlockTemplatesFilesCollection::toFileName()), so
e.g. "foo/bar" becomes a path "foo/bar.titleblock" -- since "foo/"
essentially never exists as a directory, the underlying file write
fails, but that failure was never surfaced:
- TitleBlockTemplateLocation::isValid() only checked for an empty
name, so an invalid name still counted as "valid" and got passed
through to save.
- QETTitleBlockTemplateEditor::saveAs(const TitleBlockTemplateLocation&)
discarded the bool result of setTemplateXmlDescription() and
unconditionally returned true, marking the undo stack clean as if
the save had actually succeeded.
Fix:
- isValid() now also rejects names containing \ / : * ? " < > |,
matching the character set that's actually unsafe once the name
becomes a filename.
- saveAs() (the no-arg entry point that asks the user for a location)
now shows a clear error dialog when the entered name is rejected,
distinguishing "user cancelled" (location.name() empty) from
"name was invalid" (non-empty but rejected by isValid()).
- saveAs(location) now checks setTemplateXmlDescription()'s return
value and shows an error dialog instead of reporting false success
on any future/other write failure, not just this one.
Verified: clean rebuild, only the intended files recompiled and
linked successfully. Live-tested under Xvfb: creating a new template
and using "Enregistrer sous" with the name "foo/bar" now shows
"Le nom « foo/bar » n'est pas valide : il ne doit pas contenir les
caractères suivants : \ / : * ? " < > |" instead of silently doing
nothing; reopening the save-as dialog afterward showed the name field
correctly empty (nothing was partially written). Saving again with a
valid name ("mytemplate_valid") completed with no error dialog, and
the resulting mytemplate_valid.titleblock file was confirmed present
on disk in the user's title-block collection directory.
ProjectView::askUserForFilePath() only appended the .qet extension when
FLATPAK_ID/SNAP_NAME were NOT set, on the assumption that the
xdg-desktop-portal file dialog used by sandboxed Snap/Flatpak builds
always appends the selected filter's extension itself (avoiding a
double ".qet.qet"). In practice, on the reporter's Snap/Ubuntu 22.04
setup the portal dialog does not append it, so the environment-based
skip left Save As producing a file with no extension at all.
Portal behavior isn't something QET controls or can reliably detect via
environment variables -- it depends on the desktop's actual portal
implementation/version. Rather than guessing per-environment, normalize
unconditionally: strip any existing .qet suffix (case-insensitive) and
re-append exactly one. This produces the correct single extension
whether or not the dialog already added it, on every environment.
Verified: clean rebuild, only the intended object file recompiled and
linked successfully. Wrote a standalone test of the normalization logic
covering no-extension, already-has-extension, uppercase-extension, and
a literal dot in the base filename -- all four produced exactly one
correct ".qet" suffix with no double-extension and no missing extension.
Not verified: the actual Snap-sandboxed portal dialog behavior itself,
since building/running the Snap package and testing its file-save
dialog under a portal is outside what's practical to set up in this
sandbox. Confidence rests on the fix removing the environment-guessing
entirely in favor of unconditional, dialog-implementation-agnostic
normalization, which is correct regardless of what the underlying
dialog does.
