Document Search & Replace and the nomenclature/summary query builder
Both were confirmed still-real gaps from the survey: Search & Replace
(sources/SearchAndReplace/, ~3,180 lines) was a single features.md bullet,
and the query-builder UI (sources/dataBase/ui/, ~1,088 lines) was only
named once inside project_database.md as a pointer to ElementQueryWidget,
with no workflow documentation.
## Search & Replace
The name is misleading and worth correcting up front: this is not text
find/replace. SearchAndReplaceWorker::applyChange() shows the real
semantics -- an empty field leaves a property untouched, a filled field
replaces it wholesale (never a substring swap), and a reserved sentinel
string (set via a per-field checkbox, never typed by the user) explicitly
clears a field. Three states per field, not two. Traced through
setupLineEdit()'s own doc comment and applyChange()'s three-branch
behavior to be sure of this before writing it down.
## Nomenclature / summary query builder
ElementQueryWidget (element_nomenclature_view) and SummaryQueryWidget
(project_summary_view) are a visual SELECT builder: two-list column
picker, seven filter modes with their exact SQL traced from
on_m_filter_le_textEdited()'s switch statement (No filter/Not empty/
Empty/Contains/Does not contain/Is equal/Is not equal), group-by and
count, an "Edit SQL query" escape hatch, and named saved configurations.
Explicit about what it is not: not a general SQL client (bound to one
view, can't change the FROM even in raw-SQL mode), and not the same
column set as --export-bom, which was verified to hardcode its own fixed
list in cli_export.cpp rather than sharing this widget's choices.
Links the existing one-line Search & Replace mentions in features (all
three languages) to the new page. EN/FR/DE for both.
Document DXF: two unrelated features reduced to one bullet each
sources/createdxf.*, sources/dxfpaintdevice.*, sources/dxf/dxftoelmt.*
total ~1,780 lines. The only wiki coverage was a single repeated bullet
-- 'DXF -- CAD format for collaboration' -- across features, faq and
user_manual, in all three languages, describing neither direction
accurately: it reads as one feature, and it's actually two that share
nothing but a file extension.
Export (File -> Export, alongside PDF/PNG/SVG, in-process) reuses every
item's existing paint() code through a custom QPaintEngine
(DxfPaintEngine) rather than a separate DXF renderer -- documented from
that class's own thorough header comment, including the real fidelity
table it specifies: rectangles and filled paths lose their fill (no
HATCH primitive in this DXF dialect), arcs become straight-line chords,
and images become position-preserving placeholder rectangles since DXF
has no raster entity here. No CLI verb exists for it, unlike PDF/PNG/SVG.
Import (element editor only, not the diagram editor -- File -> Import a
DXF file) is a symbol-authoring tool: it shells out to dxf2elmt, a
separate third-party program QET does not bundle, the same external-tool
pattern as qet_tb_generator already documented in api_reference. Traces
the actual call: , stdout read as .elmt XML, pushed
onto the element editor's undo stack as one operation.
Makes explicit what neither direction is: not a way to place a DXF
drawing on a folio, not round-trip safe (export's own limitations rule
that out before even considering the code is entirely separate), and not
a full CAD interchange path -- no layers, blocks or metadata, just
primitives.
Links the existing one-line mentions in features/faq/user_manual (all
three languages) to the new page instead of rewriting them, since they
are fine as list bullets. EN/FR/DE.
