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.
This avoid to parse the same element definition each time user drop the same element in the diagram.
Only the first element build the picture, all other get the created picture which is shared.
2- For use the "implicite shared" QPicture and QPixmap of element, now this isn't the element who build her picture, but a dedicated class who made only this job : build the QPicture and QPixmap of elements.
3- With the two previous novelty, the class CustomElement and GhostElement are became useless, and so was removed.
Some few member function of CustomElement was moved to Element.

If the text is wider than the defined width, the text is broken into multiple line.

From now, the class ElementTextItem is not anymore use in qet. Every texts in a diagram are DynamicElementTextItem.
the Xref item was adapted to dynamic text.
Previously, the comment and location, displayed as a "static text" below the "old text" tagged "label" are now automaticaly converted to DynamicElementTextItem, so visually, these texts stay unchanged

Tree Widget for edit the element text item :
-Change a value of a spinbox with the mouse wheel, apply the change in live (no need to press enter or leave focus).
-Remove the sub-level of source of text.

the displayed text of the dynamic text item is up to date according to the formula

when text is owned by a folio report, the only information available to the text is :
the label (formula used for the Xref between linked report), the function of the potential and tension/protocol of the potential.
Unlike other elements there is no more information, because a report is not a real element.

First : If the parent element of the text item is a slave,
the info use to create the text (both if option are 'element info' or 'composite text') are taken to the linked master element, and not the slave.
If the salve element is not linked, no information is taken.
Second : if the text is composed with the variable 'label' of the master (both if text from are 'element info' or 'composite text') double click on the text, act like a link and go to the master.
