Listing GuiPrivate unconditionally in QET_COMPONENTS breaks the whole
Qt5 configure: find_package(Qt5 COMPONENTS GuiPrivate) looks for a
Qt5GuiPrivateConfig.cmake that has never existed - Qt5 creates the
Qt5::GuiPrivate target implicitly together with Gui. Only Qt6 requires
(and provides) the explicit component.
Move the request into a QT_VERSION_MAJOR-guarded find_package after the
main one, both for the application and for tests/catch (whose targets
link Qt::GuiPrivate via QET_PRIVATE_LIBRARIES). Fixes the msys2/Qt5
Windows CI configure failure:
"Could not find a package configuration file provided by Qt5GuiPrivate".
Verified: Qt 6.11 configure passes and the Qt6::GuiPrivate target is
created (the private-module warning now fires from the guarded call).
The Qt5 path simply no longer requests the component, restoring the
pre-existing implicit behaviour.
Provide a small KAutoSaveFile-compatible implementation for the no-KF5 build path and use it to keep the existing crash-recovery code active when BUILD_WITH_KF5=OFF.
The normal KF5 build still uses the KDE KAutoSaveFile implementation.

The BUILD_WITH_KF5 option was checked with DEFINED, so passing -DBUILD_WITH_KF5=OFF still entered the KF5 setup path.
Skip the KF5 setup when disabled and provide small Qt-only replacements for the KDE color widgets used by .ui files in that build mode.

Move the PDF cross-reference hyperlink logic out of ProjectPrintWindow
into a standalone translation unit so it can be reused (the CLI PDF
export will call it next):
- injectCrossRefLinks(): emits the URI link annotations for a diagram's
cross-references and folio reports. The scene-to-page mapping is passed
in as a PageGeometry (transform + devToPdf + source-rect lookup) so each
caller supplies its own correct geometry, rather than the helper assuming
a QPrinter.
- convertUriToGoTo(): the PDF post-processor, moved verbatim.
ProjectPrintWindow stays a pure caller: it builds its PageGeometry from the
printer page layout exactly as before and calls the helper. No behavioural
change to GUI PDF export; no class-structure changes.
Per review guidance on #483.
Implements the long-requested batch/headless export
(bugtracker #171, GitHub #309): render a project's diagrams to files
without opening the GUI.
qelectrotech --export-pdf <project.qet> <output.pdf> one multi-page PDF
qelectrotech --export-png <project.qet> <output_dir> one PNG per diagram
qelectrotech --export-svg <project.qet> <output_dir> one SVG per diagram
main.cpp detects an export request before SingleApplication is created (so the
arguments are not forwarded to a running instance), spins up a plain
QApplication for rendering, and exits with the export's status code.
Rendering reuses Diagram::render() over
BorderTitleBlock::borderAndTitleBlockRect(), the same geometry the GUI
print/export path uses, so output matches the editor. Image files are named
NN_Title.<ext>.
New files: sources/cli_export.{h,cpp}, registered in
cmake/qet_compilation_vars.cmake.
directly to the related component on its folio, framing the target element.
When a project is exported to PDF, every cross-reference becomes an internal
link. Four kinds are covered:
- **Master → contact**: the contact list on a coil/relay (`CrossRefItem`)
- **Folio report → report**: report element labels (`DynamicElementTextItem`)
- **Slave → master**: the `(folio-position)` reference shown on a slave
(both standalone `DynamicElementTextItem` and grouped `ElementTextItemGroup`)
Clicking a link navigates **inside** the open document (no new viewer
instance) and zooms to frame the target element.
1. **Injection** (`printDiagram`, only when the paint engine is a `QPdfEngine`):
link rectangles are added with `QPdfEngine::drawHyperlink()`. The scene→page
mapping is rebuilt to match exactly what `QGraphicsScene::render()` does
(top-left anchored, `KeepAspectRatio`, **no centering**), and rectangles are
passed in device pixels — `pageMatrix()` already applies the 72/resolution
scale and Y-flip internally.
2. Each link URL encodes the target page and the target element's rectangle, in
PDF points on its own page: `#page=N&fitr=L_B_R_T`.
3. **Post-processing** (`pdfConvertUriToGoTo`, run after the painter is closed):
the `/S /URI` annotations are rewritten to native `/S /GoTo` actions with a
`/D [pageObj 0 R /FitR L B R T]` destination, and the xref table is rebuilt.
Pages are enumerated from the `/Pages /Kids` tree (reliable), not by scanning
for `/Type /Page` in raw bytes.
- `sources/print/projectprintwindow.{cpp,h}` — injection + post-processing
- `sources/qetgraphicsitem/crossrefitem.{cpp,h}` — `hoveredContactsMap()` accessor; store text rect for hit area
- `sources/qetgraphicsitem/dynamicelementtextitem.h` — `slaveXrefItem()` / `masterElement()` accessors
- `sources/qetgraphicsitem/elementtextitemgroup.h` — `slaveXrefItem()` accessor
- `qelectrotech.pro`, `cmake/qet_compilation_vars.cmake` — enable Qt gui-private headers (`<private/qpdf_p.h>`)
- **Fit-to-page mode only.** Links are not injected in tiled mode (multiple
pages per folio), which would require a per-tile transform.
- Uses Qt private API (`QPdfEngine::drawHyperlink`), stable since Qt 4 but not
part of the public API; the build links against `gui-private`.
- Page-tree enumeration assumes the flat `/Kids` array Qt produces (no nested
page trees).
- The frame zoom is controlled by two constants in `destRectPdf` (`pad`,
`minSide`) and can be tuned.
- Tested on Qt5; the `/Kids` parsing and `pageMatrix` behaviour are identical on
Qt6.
Those desktop MIME types were needed only with KDE up to 3.x, as it
used to have its own desktop-based MIME type system. KDE 3 is EOL for
many years now, and there are already XDG MIME types.
These files are the bare XML definitions, and they are automatically
generated by update-mime-database (part of shared-mime-info) on update
(e.g. by distro hooks) or manually. Keeping them in the sources, and
installing them, is definitely not correct, as qelectrotech.xml is
their canonical definition.
Hence, drop them from the sources, together with references to them.
