Group and Ungroup are enabled in slot_updateComplexActions(), which ran
only when the selection changed. Grouping, ungrouping and undoing either
leave the selection as it is, and so does right-clicking an item that is
already selected, so the actions kept the state from before. The
right-click menu hides disabled actions, so it went on showing Group on a
selection that was now one group (and Ungroup after ungrouping), and the
one that would work was not in the menu at all.
Diagram::setItemGroup() is the one place an item's group changes (group,
ungroup, undo, redo, paste), so it now emits itemGroupChanged() and the
editor refreshes its actions on it, beside the selectionChanged
connection.
Checked in the GUI on two free texts, saving after each step: right-click
> Group, right-click again, Ctrl+Z, right-click again. Before, the second
and third right-clicks offered Group again and did nothing (both saves
still grouped). After, they offered Ungroup and ungrouped (0 grouped
texts in both saves); Group, Ungroup, Group also round-trips.

A wire whose terminals have uuids is saved against them, and on load it
is reattached to a terminal with that uuid or dropped, with only a qDebug
line. Re-importing a changed symbol and choosing "replace" swapped the
project's definition for one whose terminal uuids differ; the placed
symbols kept the old ones until the project was reopened, so every wire
on them was lost at the next open, silently, and gone for good at the
next save.
- XmlElementCollection::copyElement(), where an embedded definition is
overwritten, carries each old terminal uuid onto the new terminal at
the same place and orientation (TerminalUuids::keep()). Terminals that
moved, and new ones, keep their own.
- Diagram::fromXml() records wires it could not reattach, logs them, and
the editor lists them in one warning after opening a project.
Measured on 2612_ats_singlephase.qet with the stored splice's terminal
uuids made to differ from the collection's: replace, save, reopen loads
34 of 131 wires on master, 131 with this change (GUI, both arms).
tst_terminaluuids covers keep() and runs the real loader.

Clicking an item of a group selects the whole group (#1070). Clicking
again on one of its items is meant to select just that item, to edit it
on its own -- what discussion #1070 proposed -- but the second click
selected the whole group again: Qt left only the clicked item selected on
release, and the group completion pulled the others back in.
A press on a member of a group that is selected whole now notes that
member (ItemGroups::memberToPick(), which also finds the member when the
click lands on a symbol's own text). If the click ends without a drag and
Qt has left only that member selected, the selection stays so. A drag
still moves the whole group; Ctrl+click keeps its meaning; a group of one
is not picked from.
In the GUI, on two grouped texts: one click then Delete removes both
(master and this); click, click again, Delete removes only the clicked
text here, both on master; dragging after one click moves both texts by
the same amount on both. tst_itemgroups: 5 new checks; removing the
whole-group or the group-of-one condition fails one each. ctest 24/24.

Symbols, free texts, shapes and pictures can be grouped from the Edit
menu, the selection's context menu or the command search. Clicking one
member selects the group, so moving, copying and deleting act on all of
it; Ctrl+click on a member deselects the group; a rubber band touching
part of a group selects all of it when released. No default shortcut:
Ctrl+G is "jump to element".
A group is not an object in the scene. Each member keeps its place and
carries the group's uuid (QGraphicsItem::data()), saved as a "group"
attribute written only when set: a project without groups saves exactly
as before, and older versions open a grouped one and ignore the groups.
Re-parenting under a QGraphicsItemGroup would have made every member's
position group-relative; ElementTextItemGroup already needs nine special
cases for that.
- Selection is completed on clicks and at the end of a rubber band, not
on every selectionChanged(): export, search and Tab select items
themselves and must not have groups pulled back in.
- Project database: group_uuid on element, shape, independent_text and
image, kept in step by projectDataBase::itemGroupChanged().
- Paste and folio duplication give each source group one new uuid.
- Undo of Ungroup restores each item's exact group.
Builds on #1065 (uuids and database rows for texts, shapes and images).

Texts snapped to the folio grid, so the first drag of an off-grid label
pulled it sideways by up to half a grid step (discussion #1020). Texts
now snap to a fraction of the folio grid, chosen from a "Textes 1:N"
button in the View toolbar and a menu under Affichage: Off, 1:1, 1:2,
1:2.5, 1:5, 1:10. Because the step divides the folio grid, texts on
different elements still line up. Ctrl still places a text freely.
1:1 is the default and matches the previous behaviour. The setting is
stored in QSettings; nothing changes in saved projects.
All five text movers switch together: element texts, text groups,
texts moved with a selection, conductor texts and independent texts.

The inverted painting, the rubber band replay and the changed()
receiver lived in DiagramView, which the unit tests cannot link, so the
update-flag regression was only covered through a stand-in view. They
now live in PaletteGraphicsView, a QGraphicsView subclass with no
other dependency, and DiagramView derives from it. The view tells a
subclass through paintingInverted(bool) when it renders for an
inverted display; DiagramView forwards that to the diagram. The grid
dot rule moves out of Diagram::drawBackground into
QET::Palette::gridDotColor().
tst_qetpalette now links the real class: gridDotColorSoftensInvertedDots,
paletteViewFollowsThePalette (light sheet, dark sheet at text contrast
with a red box still red and the paintingInverted calls in order, back
to light), paletteViewKeepsSceneUpdatesFlowing (three whole-scene
updates and a selection each repaint, scene set after construction),
paletteViewDrawsTheRubberBand.
On a dark palette the folio view paints through QGraphicsView::render()
instead of onto its viewport. In that case QGraphicsView never clears
the scene's "update everything" flag, and while the flag is set every
further QGraphicsScene::update() and item update is dropped: from the
second Diagram::update() on, the grid toggle, the white/gray toggle and
even a selection waited for an unrelated repaint. With a receiver on
QGraphicsScene::changed() the scene clears the flag before it emits, so
DiagramView now connects an empty receiver in its constructor.
While the view paints for inversion, Diagram draws the grid dots a
third of the way from the sheet color to black, so they come out as a
soft gray on the dark sheet instead of as bright as the ink. Printing
and export never take that path.
Test in tst_qetpalette: sceneUpdatesReachARenderedView.
a) paste
- conductor does not move
- pressing escape does not abort
- pressing anything during the process crashes the program instead of aborting
b) similar issue with the escape not working fixed for graphics items, texxt fields (and probably others)
Diagram::m_uuid was created in the constructor and never written, so a
folio got a new uuid on every load. Inside a running instance that is
enough (the project database keys on it), but nothing outside it could
tell which folio is which: in the file, folios were only identified by
their position.
Motivation
More and more .qet projects live in version control -- a Git repository
on GitHub or GitLab, reviewed through pull requests, sometimes edited
by several people -- or are synchronised through a cloud or key-value
store. A .qet file is plain XML, so in principle it can be diffed,
merged and split up, but only if the same folio can be recognised in
two versions of the file. Today it cannot:
- Inserting, deleting or reordering a folio shifts every following
<diagram> element. A line-based diff, and GitHub's review view, then
pair up unrelated folios and show far more change than was made.
- A three-way merge of two branches that both touched the project has
no way to match "folio 3" on one side with "folio 3" on the other if
either side reordered folios.
- Any tool that wants to say "folio X changed in this commit", keep
per-folio history, lock a single folio, or store folios as separate
objects has nothing stable to key on. The title and the folio number
are user-editable and not unique.
Element uuids are already persisted and used for cross-folio links, so
the file format already relies on uuids for identity; the folio itself
was the missing piece. A stable folio uuid is the prerequisite for
later work towards better version control support: per-folio diffs and
locks (check-out / check-in), and possibly storing a project as a
directory with one file per folio.
Change
Write the uuid as an attribute of <diagram> when the whole content is
saved, and restore it first thing when the project is loaded, before any
item is created. Older versions ignore the attribute, so files stay
readable in both directions.
Folios without a uuid: why not a random one
The obvious migration -- keep the random uuid created by the
constructor and save it -- conflicts with #754 / #779: saving an
unmodified project must give the same bytes every time. Every example
project predates the attribute, so each load would invent different
uuids and write them out. Measured on the 24 example projects (resaved
3-4x each from the same original, QT_HASH_SEED=0 so that QDom's
attribute order is stable, isolated HOME per run):
upstream master 23/24 byte-identical
persist, random uuid 0/24
persist, derived uuid (this) 23/24
The remaining project, schema_indus.qet, differs only in element uuids,
the known residual #779 leaves for elements; its folio uuid is stable.
This is the same problem #779 solved for conductors by not writing an
invented uuid back at all. That is not an option here: legacy folios
would never get a persistent uuid, which is the whole point of the
change. Instead, a folio without a uuid gets a name-based (version 5)
uuid, derived only from data read from the file:
QUuid::createUuidV5(<fixed QET folio namespace>,
"legacy" + project title
+ position of the folio in the file
+ folio title)
- The same input file always yields the same uuids, so resaving an
unmodified legacy project stays reproducible.
- The uuid is derived once, at load time, and saved from then on. After
that it is read, never recomputed: renaming, reordering or editing
the folio later does not change it. Renaming in the same session as
the migration does not change it either, since it was derived from
the title as loaded.
- Two people opening the same legacy file on different branches get
the same uuid for each folio, even if one of them reorders or renames
folios before saving. With random uuids the two branches would
disagree about every folio and a later merge could not match them.
- The folio content is deliberately not part of the name: QDom keeps
attributes in a hash whose iteration order changes between runs, so
hashing the content would need a canonical form for no real gain.
Folios are only guaranteed unique within their project. Two unrelated
legacy projects with the same title and the same first folio title get
the same uuid for that folio; anything keying folios globally has to
combine the folio uuid with a project identifier. (The project uuid is
not persisted yet; that is a separate change.)
Duplicated uuids
A hand-edited or merged file can contain the same uuid twice, e.g. a
folio copied by duplicating its XML block. Since the uuid is used as a
key, the second folio gets a derived uuid as well ("duplicate" + the
clashing uuid + the same inputs as above), so this case is
reproducible too. Should a derived uuid ever be taken already, which
takes a hand-crafted file, the name is salted with a counter until it
is free.
The namespace uuid is fixed in the code and must never change, or every
legacy folio would get a different uuid.
Tests (Qt 6.4, offscreen, qelectrotech --resave / --set-titleblock)
- 24 example projects, 3-4 resaves each from the same original: results
above; all folio uuids identical across runs, no duplicates within
any project.
- Resaving an already migrated file is byte-identical to the first
output.
- Renaming a folio in a migrated file keeps its uuid.
- Swapping two <diagram> blocks in a migrated file: each uuid moves
with its folio.
- Migrating and renaming in the same run (--set-titleblock title=...
on a legacy file) gives the same uuids as a plain resave.
- A file with a duplicated uuid: the second folio gets a new uuid, the
same one on every run.
- A migrated file opened with upstream master loads normally; the
attribute is ignored and dropped on save.

Implements the second pillar of #574: keyboard-driven selection on the
diagram canvas.
Tab / Shift+Tab select the next / previous item on the current
diagram, cycling through items() (z-order) and wrapping at either
end. If nothing is selected, Tab selects the first item and
Shift+Tab the last. Skipped while a text item has focus, for the
same reason arrow-key movement already guards on !focusItem().
Candidates use the same "what counts as a real selectable diagram
item" filter (QetGraphicsItem / DiagramTextItem / Conductor) already
established by Diagram::invertSelection(), so the cycling order
always matches what a user could reach by clicking.
Getting Tab to actually reach the scene needed two separate fixes,
each independently discovered by empirical testing rather than
assumption:
- QWidget (DiagramView) intercepts Tab/Backtab for widget focus-chain
traversal before generating a key event at all. Overriding
DiagramView::focusNextPrevChild() to return false disables that.
- QGraphicsScene (Diagram) has its own, separate item-focus-chain
traversal, checked before keyPressEvent() is ever reached. The
obvious fix -- overriding Diagram::focusNextPrevChild() the same
way -- silently does nothing on Qt 5, because
QGraphicsScene::focusNextPrevChild() only becomes virtual in Qt 6
(guarded by the QT6_VIRTUAL macro); a compile error surfaced this
immediately when attempted directly, rather than shipping a fix
that worked on Qt 6 and silently no-opped on Qt 5. Intercepting
QEvent::KeyPress in Diagram::event() instead is virtual on every Qt
version and sidesteps the scene's internal traversal entirely.
Also adds Diagram::selectAllConductors() / selectAllTextFields(),
wired up as two new actions in the existing select_all /
select_nothing / select_invert action group in
qetdiagrameditor.cpp, so they appear in the Edit menu and go through
the same QAction -> data() -> selectGroupTriggered() dispatch as the
existing selection commands.
Verified end-to-end in a real running session (Xvfb + xdotool) with
a multi-transistor schematic: Tab/Shift+Tab correctly move a single
selection forward/backward through elements and text fields
(confirmed via the properties panel updating to each new item and
the visual selection box moving on canvas); Tab/Shift+Tab from no
selection correctly select the first/last item; "Select all
conductors" and "Select all text fields" each correctly select every
matching item and deselect everything else.
See discussion #574.

When copying and pasting selected areas, right-aligned dynamic text in
report and slave elements was not displayed correctly. The text
insertion point was always shifted to the left by the text width.
To correct this, the insertion point of dynamicElementTextItems is reset
to its origin insertion point before writing to clipboard.
Remove setter function : void BorderTitleBlock::setTitle(const QString
&title)
Remove singal diagramTitleChanged from BorderTitleBlock and use instead
the signal informationChanged.
Before this commit :
ElementPropertiesWidget emit a signal of Diagram to edit an element, and
the signal goes up from Diagram -> DiagramView -> ProjectView ->
QetDiagramEditor and QetDiagramEditor call a static function.
Now :
ElementPropertiesWidget call the static function itself and that all.
All unnecessary signals are removed.
