The box hides the name of the terminal on the sheet only: the element
keeps all of its data, and with the labelling split the terminal keeps
its number, drawn once - in its own field when the symbol has one,
alone in the label field when it has not.
Only a terminal may have its name undrawn: the box is shown for the
element type Terminal alone, and Element::labelShown() obeys the
stored information for a terminal only. The choice is stored as the
element information "label_shown" = "false" and only that, so files
of every element which still draws its name stay exactly as they are.
Multi-selection: the flag appears for terminals only and counts an
absent information as "shown", so a mixed selection shows the box
ticked only when every terminal has it ticked.
Includes four test cases: hidden name keeps the stored data, keeps
the number without a number field, leaves the number to its own
field, and a non-terminal draws its name whatever the file says.
Selecting several elements left the Selection properties panel blank and
Edit (Ctrl+E) disabled, so giving many elements the same supplier or
manufacturer meant editing them one by one.
The panel now shows the Information fields for two or more elements, or
for elements selected with other items (left unchanged, and counted in
the panel's header). Ctrl+E opens the same editor as a dialog when only
elements are selected.
- A field shows the value every element shares, or "Multiple values".
Left alone, each element keeps its own value; typed text goes to every
element; the erase box clears the field on every element.
- A restore button per field, and Reset, bring back the values the
elements had.
- One apply is one undo step. The keystrokes typed in the panel merge
into one step but never into an earlier change of the same elements
(a paste of element information, another edit).
- Numbering scheme, label freezing and the number picker are left out:
they are about one element. Custom properties are kept as they are.
Also:
- An element's own texts, selected with it by Select all, count as part
of the element, not as other items.
- ElementInfoWidget::reset(): Reset in the element dialog now brings back
the Information tab's values; it did nothing.
- The panel opens an element's editor on the tab picked last, instead of
the first tab, after the selection went to something else and back.
Test: tst_multielementinfo.
