Edit > "Miroir horizontal" (M) and "Miroir vertical" (F), also in the
folio's right-click menu, mirror the selected symbols in place. The keys
are the ones the element editor uses for the same two actions.
An element keeps two mirrors about its own axes, applied before its
rotation, and saves them as mirror="horizontal|vertical|both" on its
<element> (written only when set, so other projects save byte for byte
as before). On a symbol turned by 90 or 270 degrees, a mirror of the
folio is the other mirror of the symbol itself, so the rotation never
changes: a label kept upright does not swing round, and "Pivoter" still
turns a mirrored symbol clockwise.
- Terminals face the mirrored way (Terminal::orientation()), so wires
follow.
- The symbol stays where it was: its centre is kept, on the grid, since
the hotspot is often a corner.
- Texts read normally. The element's texts, text groups and cross
reference are mirrored a second time about the centre of their own box
(Element::keepReadable()), and ElementPictureFactory draws the texts
of the symbol itself the same way, in a cached picture per mirror.
Groups and cross references held at the bottom of the folio stay
centred under their element.
- DXF export mirrors the symbol's lines, arcs and texts.
- Scripting: qet.mirrorElement(folio, uuid, vertical) and
qet.elementMirror(folio, uuid); live mode may run both menu commands;
the MCP server gets a mirror_element op and qet_diff reports mirrors.
Not done: the parts of a PLC table drawn at run time
(Element::drawPlcTable()) are not kept readable on a mirrored PLC; the
project database has no column for it, as it has none for the rotation.
Test: tst_scriptmirror mirrors a symbol through --run, checks every
terminal's side and facing, the round trip, undo, a save and reload,
and a symbol turned by 90 degrees.
