DynamicElementTextItem::updateLabel() resolved %{label} in composite
text using the stale value from elementInformations()["label"], which
is only set once at load time and never updated when the folio/page
number changes.
Use element->actualLabel() instead, which resolves the label formula
(including %F, %f, %id) against the current folio at call time.
Two bugs reported by @arummler on #591 after merge:
"It works but to select the text field one has to right click on
it...I think there are competing handlers or something."
"the drag elements should be on the border of the box. In the
moment they appear directly left and right from the text."
Both reproduced headlessly (scripts/qet-gui-dialog.sh) against a fresh
build of current master and root-caused before touching anything.
Selection: DynamicElementTextItem::mousePressEvent() forwards a plain
click (no Shift) straight to parentElement()->mousePressEvent(), by
design and pre-existing -- it's what lets dragging a symbol by its own
label move the whole symbol rather than just the label. That's correct
and untouched here. But it means a plain click leaves the *parent*
selected, not the text, and #591's handles were wired only to the
text's own ItemSelectedHasChanged -- so they were only reachable via
Shift+click or a right-click's context menu (which happens to select
the item under the cursor for its own context menu, unrelated to the
Shift path), neither of which anyone reaches for to resize a text.
Confirmed with screenshots at each step, including that Shift+click
already reached the existing (if misplaced) handles correctly.
Fix: DynamicElementTextItem::refreshResizeHandlesVisibility() shows the
handles when either the text itself or its parent element is selected,
and Element gets an itemChange() override (it had none) that calls it
on each of its own texts when the element's own selection changes. Both
sides driven from itemChange(), Qt's own hook for exactly this and the
same one already used for the text's own selection.
First attempt drove this from paint() instead, since the PR's own
updateResizeHandlesPos() already runs there. That crashed reproducibly
(SIGABRT) on deselecting a text: paint() runs while QGraphicsScene
iterates its item list to draw it, and addResizeHandles()/
removeResizeHandles() mutate that list via QGraphicsScene::addItem()/
removeItem(), which cannot safely happen mid-iteration. Caught it with
the same headless repro before it went anywhere near a PR, moved the
logic to itemChange(), and re-ran the full sequence -- select, resize,
undo, deselect, twice through -- clean.
Position: updateResizeHandlesPos() placed the handles on frameRect(),
which is a box sized to the text's natural (idealWidth()) content and
then re-centred inside boundingRect() -- it does not grow with
textWidth(). Once a text has been widened, frameRect() stays tight
around the glyphs while boundingRect() -- the box QGraphicsView actually
outlines as the selection, and the box a user drags relative to -- grows
around it, leaving the handles stranded well inside the visible
selection border. Fix: position them on boundingRect() instead, which
does track textWidth(); confirmed by widening a text and checking the
handle lands exactly on the new edge rather than partway across it.
Verified headlessly end to end on the original report's own element
("motor off" on grafcet.qet, folio 1): a single plain left-click (no
Shift, no right-click) now shows both handles at the true box border;
dragging resizes correctly and the handle tracks the growing edge;
Ctrl+Z restores the -1 auto-width sentinel and the handles stay at the
reverted position; clicking away removes them; repeated twice with no
crash. Qt 6.10.2, ctest 12/12, no new warnings in either changed file.

Dragging an element's text -- its label, article number, any of its
information fields -- moved it in free one-unit steps while everything
else in the editor snapped to the grid. Reported by pki791 in #923 for
labels moved with Shift.
QET moves a text with the mouse along five paths. Four snap and let Ctrl
place freely:
DiagramTextItem::mouseMoveEvent an independent text
ElementTextItemGroup::mouseMoveEvent a group of element texts
ElementTextsMover::continueMovement every OTHER selected element text
QetGraphicsItem::setPos elements, images, shapes
DynamicElementTextItem::mouseMoveEvent, the text actually under the
cursor, ended "setPos(new_pos)" with no grid and no modifier check. It is
otherwise the same function as the group's, which is why this reads as an
omission rather than a decision: the line this adds is that function's,
character for character.
The inconsistency was visible in one gesture. With two element texts
selected and one of them dragged, ElementTextsMover skips the driver item
and snaps the rest, so the text under the cursor was the only one on the
folio that did not land on the grid.
Verified on a virtual display (Xvfb + openbox) against a two-lamp fixture,
grid 10, reading the saved positions rather than the screen:
Shift+drag the label before (32.95, -11.55) -> (7.95, 23.45) off-grid
after -> (10, 20) on-grid
the co-selected label (10, -10) -> (50, 20) on-grid, before and after
Shift to grab, then Ctrl -> (7.95, 23.45) off-grid, free placement kept
The last line matters: moving an element text needs Shift at press, and
the modifier is read at move time, so Ctrl still places freely -- press
with Shift, hold Ctrl to drag. Holding both from the press is a different
gesture, reserved by DiagramView::isCtrlShifting() for the view's mode
switch, and does not move the text at all. Nothing that was possible
before is lost.
Worth knowing when reviewing: 470 of the 492 element texts in the 24
example projects (95.5 %) sit off the grid today, because element
definitions place their default text at fractional offsets. The first
drag of almost any existing label will pull it onto the grid, by at most
half a grid step.

When duplicating a diagram page, copied slave elements retain stale
data from the source: labels, descriptions, link references, and PLC
master information (type, address, function, comment, cross-ref, timer
values) remain in the copies.
Fix by adding clearPendingLinks() to Element to prevent copies from
linking back to source elements via stale UUIDs, and by cleaning up
copied element data after fromXml():
- Slaves always lose their label, formula, comment, location, and
PLC master data, since their text comes from a master element which
is not available on the copy. The displayed text on slave elements
is cleared directly via setPlainText(), but UserText items (free
text typed by the user) are preserved.
- For PLC slaves, setElementInformations() is called without
m_block_alignment so that elementInfoChanged() can run
finishAlignment() to correctly adjust text positions for the
cleared content.
- Non-slave elements respect the existing erase-label-on-copy
preference, same as PasteDiagramCommand::redo().
- Conductor labels are also reset when erase-label-on-copy is
active, matching PasteDiagramCommand::redo() (issue #413).
- Text alignment is preserved by wrapping setElementInformations()
with m_block_alignment for non-slave elements, same as
Element::fromXml().
QET had no icon theme: the 446 entries of the icon table and the 116
iconsets in .ui files each named a resource path, so an icon could only
ever be one file, and a variant for another palette or a vector source
had nowhere to go (GitHub #466, #690, #870). This adds the theme layout
without changing a single pixel; a dark variant comes in a follow-up.
The theme "qet" follows the freedesktop layout Qt's icon loader
understands. misc/make_icon_themes.py generates ico/icon-themes.qrc,
which aliases the existing ico/<size>/<name>.png files into
themes/qet/<size>/<name>.png, and ico/themes/qet/index.theme. No file
moves. The four table entries that paired a 16 pixel file with a 22
pixel file of another name (ConductorSettings, DiagramAdd,
DiagramDelete, DialogInformation) get the 22 pixel file aliased under
the 16 pixel name.
QETApp::initIconTheme() registers the theme before initIcons() and makes
it current on every platform, so a desktop icon theme cannot replace
QET's icons. Icons are then looked up by name: QIcon::fromTheme() in
qeticons.cpp and in the few places that built a QIcon from a resource
path directly, and theme="..." on the iconsets in .ui files, with the
resource path kept as fallback. Flags, color swatches, application and
MIME icons stay on their paths.
One entry does not go through the theme. The elements panel draws the
project root with ProjectFileGP in the 50 pixel slot it reserves for
element previews, and the name "project" also carries the 128 pixel
file the configuration dialog uses. On a 2x display Qt's loader picks
that file for a 50 pixel request and fills the slot. ProjectFileGP
loads the 16 and 22 pixel files directly, as before.
tests/qttest/tst_qeticons: every name in the theme resolves, the four
aliases resolve at 22 pixels, a Fusion tool button shows its icon at
3:1 with disabled weaker than enabled, and the project root icon stays
at 22 pixels or less when asked for 50 at 2x while the configuration
dialog still gets its 128 pixel file. The rendering helpers shared
with tst_qetpalette moved to tests/qttest/inkcontrast.h.
Addresses scorpio810's review of PR #890 (bugtracker #734):
- The four cas "3"/"4" bridge-skip guards now compare qRound()ed
coordinates, matching how the bridge coordinate itself is computed --
an exact != would miss a pair already grid-equal after rounding but
off by a sub-pixel remainder, and still route a degenerate bridge for
it. Verified no behavior change on the shipped corpus: per-file
self-retrace counts are identical before/after (every coordinate
there already lands exactly on-grid).
- Added tests/qttest/tst_conductorselfretrace.cpp, fixture
qet_bug_repro_resaved.qet (the report's own canonical reproduction):
exports it via the built binary's --export-svg and asserts no
conductor path is self-retracing. Confirmed it actually catches the
regression, not just passes vacuously -- reverted conductor.cpp to
master and reran: fails, 1 self-retracing path found.
Not changed in code: the cas "4" descending-branch dead-code note (kept
for symmetry, as already agreed) and the schema_unifilaire_voltaique2.qet
trade-off (flagged for the reviewer's own visual check).

- Add !parentGroup() guard to stale xref removal in updateXref()
to prevent deleting xref data that ElementTextItemGroup::updateXref()
just stored for a grouped text item.
- Replace QStringLiteral("xref") with QETInformation::ELMT_XREF
in linkelementcommand.cpp and masterelement.cpp.
- Fix indentation in plclinkwidget.cpp.
- Element::reloadPicture() now returns a ReloadPictureResult and never
clears the current drawing before a successful rebuild: a missing or
unreadable definition leaves the element as it was instead of blank.
- Elements whose size, hotspot or terminals (added, removed or moved)
differ from the new definition are not redrawn: the new drawing would
no longer match their bounding rect and live terminals.
- The action lists those elements and warns that they must be removed
and re-inserted, which deletes the conductors already connected to
them.
- Status tip states the action is not undoable.
Terminal::~Terminal() called qDeleteAll(m_conductors_list) on the live
member. Each Conductor destructor calls removeConductor() on both of its
terminals, and that removes the conductor from the same list qDeleteAll
is iterating. Mutating a QList while iterating it is undefined
behaviour; with two or more conductors on one terminal (terminal strips,
bridged terminals) it can skip a delete or delete one conductor twice,
which leaves another conductor's terminal1/terminal2 pointing at freed
memory.
The pattern dates from a00404bc9 (2021), which replaced a foreach loop
(iterating an implicit copy) with a direct qDeleteAll. It went unnoticed
until the deterministic sort keys added to Diagram::toXml() in #844
started reading pos() on both terminals of every conductor on every
save, including the periodic backup, which turned the stale pointer into
an EXC_BAD_ACCESS in QGraphicsItem::pos() while deleting an element.
Copy the list first and delete from the copy, restoring the pre-2021
behaviour. An isolated regression test (a hub terminal with 2 to 8
conductors, under AddressSanitizer) did not trigger the failure with the
old code, so none is included; the crash analysis and that attempt are
recorded in jp2images/qelectrotech-source-mirror#1.
generateConductorPath()'s cas "3"/"4" branches each insert a two-point
bridge along one axis, at a coordinate on the other axis computed as
the midpoint of depart/arrivee and then snapped to the routing grid by
a loop that walks it strictly downward until it divides evenly.
When depart and arrivee already agree on the axis the bridge would run
along, no bridge is needed at all -- the midpoint starts on the
correct, already-shared value. But the snap can still walk it off that
value, or, when it happens to already sit on the grid, the two bridge
points just duplicate depart and arrivee outright. Either way the
conductor renders with an unnecessary out-and-back excursion or a
small looping detour at a join that needed neither.
Fix: skip the bridge in exactly that degenerate case, per branch, on
the axis that branch actually bridges on. descendant and montant are
not mirror images of each other in which axis each cas guards on --
each site says so.
Verified against the report's own canonical reproduction
(qet_bug_repro_resaved.qet from the linked gist): 1 self-retracing
path -> 0. Full corpus of 24 shipped example projects (stored
segments, as shipped, not regenerated): 74 -> 65 self-retracing
conductor paths, zero regressions -- only two files changed, both
improved.
One disclosed trade-off, found while checking for regressions: in
schema_unifilaire_voltaique2.qet, 8 terminal pairs closer together
than twice the extension length (docked stubs already cross before
any bridge is considered) go from an existing small rectangular-loop
artifact to a straight out-and-back retrace covering the full gap --
same count of defective paths (8 -> 8), a different shape, still no
connectivity change either way. Not chased further; a real fix for
that narrower "crossed stubs" case is a separate piece of work.
The shipped affuteuse_250h.qet's own 12 self-retracing paths (verified
by stripping all 185 stored <segment> elements and forcing full
regeneration) are unchanged by this fix -- they are a structurally
different point-count signature (a 4-point back-and-forth reachable
from cas "1"/"2", not the cas "3"/"4" grid-snap bridge this fixes),
consistent with what the issue thread already flagged as a separate,
undiagnosed mechanism.

A placed element is drawn once from its definition at construction --
buildFromXml() only turns terminal/input/dynamic_text tags into live
child objects, every other primitive (line, rect, ellipse, polygon,
arc, text) is pre-rendered into a QPicture by ElementPictureFactory,
cached forever under the element's uuid with no invalidation path
anywhere in the codebase. Edit and save a symbol's drawing and every
already-placed instance keeps showing the old one until the project
is closed and reopened.
Fix, scoped to what is safe to do without ever risking a conductor or
a dynamic text's per-instance state:
- ElementPictureFactory::dropCache(location) forgets the cached
drawing for one location, so the next fetch rebuilds it from the
definition's current content.
- Element::reloadPicture() re-fetches and repaints one instance.
- Projet > "Recharger les dessins des éléments": walks every diagram,
drops each distinct location's cache once, then reloads every placed
instance.
Deliberately does not touch terminals or dynamic texts -- a definition
whose terminal positions moved still needs the existing remove-and-
reinsert workflow, since terminals are what conductors are attached to
and a wrong guess there would silently misconnect wires.
Verified: build clean, ctest 6/6. Triggered the new action on a real,
densely-wired project (76 elements) via exact keyboard-menu navigation
cross-checked against the menu's own addAction order -- ran to
completion, correct confirmation dialog, no crash, diagram unchanged
and uncorrupted afterward. Could not complete a live edit-and-watch-
it-update trace: opening the element editor on a selected item via
GUI automation was unreliable in this environment (same class of
friction as PR #888), and this sandbox has no file-based (common://)
element to mutate on disk as a shortcut -- every example project
embeds its elements. The mechanism itself is traced correct:
ElementsLocation::xml() for an embed:// location reads the project's
live in-memory collection DOM on every call, so a dropped cache
rebuilds from whatever was most recently saved.

The F2 color editor recolors one conductor, but the next one drawn
falls straight back to defaultConductorProperties -- the choice made
via F2 is lost the moment you place another wire, and lost again on
restart. LastUsedStyle already solves the same problem for shapes
(pen/brush) and free text (font), session-scoped and deliberately not
QSettings-backed; this extends it with a conductor color, following
the identical has/get/set shape.
F2's handler records the color after pushing its undo command.
Conductor's constructor -- the one place a new conductor's properties
are set from defaultConductorProperties -- overrides just the color
field when a session color has been recorded, leaving every other
default (style, thickness, text) alone.
Verified: build clean, ctest 6/6. Could not get a reliable headless
GUI trace of "F2 one wire, draw a new one, see it inherit the color"
-- drag-and-drop element placement under Xvfb was unreliable in this
environment (one attempt did nothing, another drew an unintended long
conductor undo didn't fully clear). The code path is otherwise
identical to the already-shipped shape/text mechanism this mirrors.

Two additional bugs found after the initial xref cleanup:
1. Undo after unlink did not restore PLC variables (PLC_TYPE,
PLC_ADDRESS, etc.) because PlcLinkWidget::on_m_unlink_pb_clicked()
never stored the current group index in the LinkElementCommand.
makeLink() only populates PLC fields when group_idx >= 0, so
the slave was re-linked but appeared empty. Fixed by reading the
group index from the master via groupIndexForElement() and calling
setGroupIndex() before unlinking.
2. m_update_slave_Xref_connection was only cleared inside the
if(m_slave_Xref_item) block in the updateXref() cleanup path.
For AlignHCenter (Text field) position, no m_slave_Xref_item
is ever created — the connections are stored in
m_update_slave_Xref_connection but never cleaned up on unlink.
On re-link, the old stale entries prevented new connections from
being established. Fixed by clearing the list unconditionally
in the cleanup path.
Conductor::paint() drew every junction as a fixed 3.0-unit ellipse,
regardless of how wide the conductor carrying it is. The conductor width is
user-settable from 0.4 to 20.0, so at anything above about 3.0 the dot is
narrower than the line it sits on and disappears entirely -- exactly when a
junction most needs to be legible.
The dot now scales with m_properties.cond_size, floored at the historic 3.0
so nothing changes at or below the default width of 1.0. Only the wide
conductors the report is about are affected.
cond_size is used rather than the pen width because the pen is inflated by 4
while the mouse is over the conductor; the junction should not grow on
hover.
Measured with a temporary trace over examples/741.qet: at the default width
the diameter stays 3.00, and with condsize="5" it becomes 15.00. Visually,
a PNG export of that widened project shows two junctions that were invisible
under the line rendering as clear dots. ctest 4/4, Qt 5.15.18.

Fourth and last instance of the ordering defect, and the inner half of the
one fixed in the previous commit. ProjectDBModel::toXml() builds each
section's role list from m_header_data.value(key).keys(), and m_header_data
is a QHash<int, QHash<int, QVariant>> -- so both levels are randomised per
process. Sorting the sections left the roles inside each section still
arriving shuffled, which showed up as <data> children with the same
section="0" swapping places between two saves.
With this, save idempotence across the shipped examples goes from 6 of 23 to
22 of 24.
The two that remain fail for unrelated reasons, not for ordering:
schema_indus.qet stores no uuid attribute on its elements at all, so
fromXml() invents a fresh one on every load; and affuteuse_250h.qet loses a
title block logo's storage attribute and renames a title block template on
save. Both are separate defects.

When a placed nomenclature or summary table cannot display every row its
model holds, checkInsufficientRowsCount() informs the user with a modal
message box. It used QMessageBox directly rather than QET::QetMessageBox,
so it ignored the non-interactive mode that main.cpp sets for the
command-line verbs, and every headless verb (--info, --resave, --export-*)
blocked forever on a dialog nobody could answer.
This is the same defect fixed in e3d11a499 for the other modals reachable
from the command line; this call site was missed.
Found with a gdb backtrace on a hung --info: the process was parked in

An element can declare contact groups and a max_slaves that disagree with
each other, and nothing reconciles them.
The element editor keeps the two in step: max_slaves sizes the contact
group table, one row per slot. Nothing does so on load, so a hand
written or generated file can carry five groups and max_slaves=2. That
loads without complaint, isFull() then caps linking at two, and
ContactGroupSelectionDialog still offers all five groups -- so the user
is shown groups that cannot be linked to, with nothing to explain why.
When groups are declared they are the slots: a slave occupies exactly
one, and the selection dialog offers exactly these. So take the limit
from the group count, which is also the number the user can see.
max_slaves stays as the fallback for the elements that declare no
groups, which today is every element in the standard collection.
No element in the collection declares contact groups, so this changes
nothing for existing projects.
Verified with two purpose-built fixtures, since no real element
exercises either path: a coil declaring five groups with max_slaves=2
now takes the limit from the groups, and a coil with max_slaves and no
groups still takes the fallback path unchanged.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The earlier commit changed MasterElement::isFull() to compare the
contacts in use against max_slaves. That was wrong, and this restores
the original comparison against the number of linked elements.
max_slaves is a number of slots, not of contacts:
- it sizes the contact group table in the element editor, one row per
slot (ElementPropertiesEditorWidget::populateSlaveGroupsTable)
- a group must match the slave's own contact count before it can be
chosen, so a 4 pole slave needs a group declaring 4 and occupies
that single group (ContactGroupSelectionDialog)
- each slave stores exactly one group index
(Element::setGroupIndexForElement)
So a coil declaring 4 slots accepts 4 slaves, whatever their pole
count. Counting contacts made one 4 pole slave fill a 4 slot coil on
its own and refuse three further links that should have been allowed.
ContactUsage stays, and its per-type tally is still what the General
tab needs: how many contacts an auxiliary block must provide is a
different question from how many slots are occupied, and only the
former wants the pole multiplier. The header now says so.

Second half of #819: where a coil declares what contacts it provides, the
General tab now reports each type as used against declared rather than as
a bare count.
NO : 3/4, NC : 1/2, inverseurs : 0/1, autres : 0/0
MasterElement::contactCapacity() sums contactCount over the element's
SlaveContactGroup list, per type, reusing the same ContactUsage tally the
used count is built on. The mapping from ElementData::SlaveState onto the
tally's own type is factored into one helper so the used count and the
declared capacity cannot classify a contact differently.
Falls back to the plain count from the previous commit when an element
declares no groups, which is every element in the standard collection
today -- nothing in the corpus declares slaveContactGroups, so this
changes no existing display.
A type used beyond what is declared reads as e.g. "1/0". That is
deliberate: it says this contact does not fit the part.
Display only. Whether a declared capacity should also feed
MasterElement::isFull() is the open question in #819 and is not touched
here.
Verified end to end against a purpose-built fixture, since no existing
element exercises this path: a coil declaring two NO groups of two, one
NC group of two and one changeover group of one parses and reports
NO=4 NC=2 SW=1 other=0 total=7, matching the declaration exactly.
tst_contactusage gains a case covering capacity summed across groups
(10 cases, all passing).
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
MasterElement::isFull() decided whether a coil had room left with
connected_elements.size() >= max_slaves
which counts linked *elements*. A slave stands for as many contacts as
its "number" kind information declares, so a 4 pole contact consumed a
single contact from the coil's budget instead of four. 36 elements in
the standard collection declare a number between 2 and 4, so this is
reachable, not theoretical.
Add ContactUsage, a header-only tally holding the two rules that are
easy to get wrong:
- a slave counts once per contact it declares, not once per element
- a changeover is counted once, as sw, and never as one NO plus one
NC. CrossRefItem::NOElements() and NCElements() both return
changeovers, so a count built by adding those two lists together
reports one changeover as two contacts.
The upcoming per-type displays (the used count in the element's General
tab, and the per-type budget on the cross reference) need exactly this
count, so it lives in one place rather than being written out three
times, and isFull() now reads it too.
The header carries no graphics dependency, so the counting rules are
unit tested on their own in tests/qttest/tst_contactusage.cpp,
following the same pattern as diagramsortkeys.h.
Verified: all 9 unit tests pass, and both rules were mutation checked
(counting elements instead of contacts fails 2 tests, counting a
changeover as both NO and NC fails 3). The 23 example projects still
load and export without crash or hang, and qet-lint reports no
regressions against its baseline.

update instead of the image a placeholder box is drawn and a warning is given during export.
Current dxf version is extremely old and does not support any image embedding. Future possible
update is the introduction of a newer dxf version export option which would allow to embed a link to an external
image file.
Shapes and images can now be resized, rotated, and skewed directly
on the canvas, not just moved. Both share one small transform
struct (rotation, then skew, then scale, anchored on a movable
pivot) and one handle widget, so a corner drag, an edge skew, or
grabbing the rotate handle behaves the same way and runs through
the same matrix math everywhere, instead of every item type
reinventing its own.
Shapes also gained a proper pen tool (bezier paths, corner/smooth/
symmetric nodes), arc support, and mirroring. Images gained
non-destructive cropping and colour-keyed transparency, both
remember their own settings, so reopening the dialog picks up
where you left off instead of starting over.
Properties dialogs for both were extended to match (position,
size, angle, skew), with undo/redo wired through for every handle
drag.
Old XML files can read easily as the transformation is only added
if needed and the old syntax is still used and understood if it is
not needed.
New QLineEdit (m_potential_le) between Type and Nom: an optional,
symbol-author-chosen grouping identifier shared by terminals that
belong to the same physical terminal within a multi-terminal block.
Stored as TerminalData::m_potential (new field, persisted as the
"potential" XML attribute, empty by default).
Used by relatedPotentialTerminal() in terminal.cpp: when
potential_isolating is enabled on a Terminal-type element, terminals
sharing a non-empty, matching potential value now stay electrically
linked to each other instead of every terminal in the block being
isolated from every other one.
Tooltip on the field for explanation
Elements already inherited QetGraphicsItem::isMovable()/setMovable() --
the same mechanism images and drawn shapes use for their "lock position"
checkbox -- but nothing exposed it in the element properties panel, and
Element::toXml()/fromXml() never persisted it.
- ElementPropertiesWidget::generalWidget(): add a "Verrouiller la
position" checkbox mirroring ShapeGraphicsItemPropertiesWidget's
m_lock_pos_cb, toggling the element's inherited setMovable().
- Element::toXml()/fromXml(): persist is_movable, same attribute name
and default-true behavior as DiagramImageItem/QetShapeItem.
Verified via headless --resave round-trip: is_movable="0" survives
load -> save unchanged, existing elements without the attribute default
to movable.
