The checkbox of a terminal element was an all-or-nothing switch: while
it was unticked every conductor property (function, wire colour,
section, number...) crossed to the other side of the terminal, and
once it was ticked nothing did at all.
Rename it to "Function separation" and let one property still cross:
the voltage / protocol, which describes the electrical node itself
rather than one side of it. Conductor::functionSeparatedConductors()
returns the conductors reachable only by crossing such a terminal --
the potential computed with the separations ignored, minus the one
that respects them -- and
ConductorProperties::applyTensionProtocolChange() gives them that one
property, in the conductor properties dialog, the selection panel
multi-edit, the script API and search/replace.
The stored element information stays "potential_isolating", so
existing symbols and projects keep their setting, and the existing
sub-case of terminals sharing a potential-group identifier is
untouched. The German translation of the new label is deliberately
left out of this commit and belongs with the other .ts updates.
New QLineEdit (m_potential_le) between Type and Nom: an optional,
symbol-author-chosen grouping identifier shared by terminals that
belong to the same physical terminal within a multi-terminal block.
Stored as TerminalData::m_potential (new field, persisted as the
"potential" XML attribute, empty by default).
Used by relatedPotentialTerminal() in terminal.cpp: when
potential_isolating is enabled on a Terminal-type element, terminals
sharing a non-empty, matching potential value now stay electrically
linked to each other instead of every terminal in the block being
isolated from every other one.
Tooltip on the field for explanation
Extend TerminalData::Type enum with three new semantic values:
- No : Normally Open terminal of a switch (SW) contact
- Nc : Normally Closed terminal of a switch (SW) contact
- Common : Common terminal of a switch (SW) contact
Update typeToString() and typeFromString() accordingly.
Fully backward compatible: existing Generic/Inner/Outer types
are unchanged. Elements without typed terminals fall back
to the previous behavior (first 2 named terminals).
terminal: expose terminalType() as public accessor
Add Terminal::terminalType() returning the TerminalData::Type
of this terminal. This allows crossrefitem and other consumers
to filter terminals by semantic role (No, Nc, Common) without
accessing TerminalData internals directly.
terminaleditor: add No, Nc, Common entries to type combobox
Expose the three new TerminalData types (No, Nc, Common) in
the element editor UI so users can assign a semantic role to
each terminal of a SW contact element.
Also fix a pre-existing bug in updateForm() where m_type_cb
was incorrectly using m_orientation_cb->findData() instead
of m_type_cb->findData(), preventing the type from being
restored correctly when selecting a terminal.
