The IO table of MasterPropertiesWidget -- the panel that opens when a
PLC master placed on a schematic is edited -- set every section to
QHeaderView::Stretch. Stretch spreads the sections evenly over the
widget and disables section dragging altogether, so the column
boundaries were permanently fixed: they could be neither widened nor
narrowed, and only the width of the whole panel had any effect.
Use QHeaderView::Interactive instead, with movable sections and a set
of default widths, so the columns can be dragged as they are everywhere
else in the application. The layout reached this way is written to
QSettings under masterpropertieswidget/plc-table-header-state on every
sectionResized and sectionMoved, and restored the next time the table
is built -- the same header-state trick the free and linked element
trees of this widget already use, except saved automatically rather
than only from the context menu.
max_slaves records how many contacts a part is expected to carry. It was
enforced as a rule the drawing had to obey, which obstructs the way both
@scorpio810 and @IBSYSLevi described working in #819: draw the schematic
first, choose the physical hardware afterwards. A limit that refuses the
link forces the hardware decision up front, which is exactly what they
said gets in the way.
Two changes, both in the UI rather than in isFull(), which stays the
query it always was:
- MasterPropertiesWidget::on_link_button_clicked() now says the limit
is reached and asks whether to link anyway, defaulting to yes,
instead of refusing outright.
- LinkSingleElementWidget no longer removes a full master from the
candidate list. That was the worse half: a master at its limit simply
was not there, indistinguishable from one that does not exist, with
nothing to say why. It now stays selectable and the user decides.
PLC masters are deliberately left alone. Their limit is the number of
declared IO slots, which is structural rather than advisory -- a link
past it would have no IO index to map to -- and PlcLinkWidget already
tells the user when it hides one, via m_hidden_masters_label.
Only coils that opt into a limit are affected: max_slaves defaults to
-1, and no project in examples/ sets it.
