Schemas now get saved with a UUID and do not have to be looked up according to the form. They can be renamed and it gets reflected in existing elements. The GUI for editing them is now much easier, e.g. forms can be reshuffled. A formula can be applied. Many options now also for conductors and sheets.

/**
|
|
@brief The AutoNumSchemeCommand class
|
|
Undoable creation, edition (rename and/or new definition) and removal of
|
|
one conductor or folio numbering scheme of a project.
|
|
|
|
A folio refers to the scheme it follows by its title, as the project file
|
|
has always had it (the title of the conductor numbering a folio reads,
|
|
the title of the folio numbering its title block follows). So a rename
|
|
moves those references with it, in the same undo step, and a scheme which
|
|
a folio still follows cannot be removed: the folio would be left reading
|
|
a numbering which does not exist.
|
|
|
|
A folio numbering is applied once: the number is written into the folio
|
|
field of the title block, in place of %autonum, and the title block keeps
|
|
the name of the numbering it came from. So a folio really depends on a
|
|
folio numbering only while its folio field still holds %autonum, and
|
|
only then can the numbering not be removed; every title block which
|
|
names it has its name moved by a rename.
|
|
|
|
Conductors keep the formula they were numbered with, and the numbers
|
|
folios show are worked out from the scheme when they are drawn: a new
|
|
definition changes what is numbered from then on, nothing is renumbered.
|
|
|
|
Counter changes made by numbering something are not edits of the scheme
|
|
and do not come here.
