The strip seen from above drew no cable at all: it had no zone for one
and no code to draw it, so a strip drawn realistically told nothing
about where its cables go while the same strip drawn schematically did.
The drawing itself was already shared between nothing -- it lived in
one style only, so it is now Helpers::drawCables() with its cells, and
both styles hand it the terminals they show. The realistic style
collects one wire exit per level spread over the width of the terminal
body, all of them leaving the strip at its bottom edge, and reserves
the zone under the strip for them as soon as one terminal carries a
cable, exactly like the schematic style does.
tst_cabletarget checks the realistic style paints under the body of
the strip when a terminal carries a cable, and drops that zone when it
does not.
The box hugged its own text, so it stayed small whatever room the end
zone gave, and its font shrank until the three lines squeezed into it.
It now spans the cross bar the cable bundle ends on -- the width the
strip already draws there -- and keeps the font of the drawing: when
its lines (Installation, Location and Label) are longer than that cross
bar, it is the box which grows, the text is never cut down to fit a box.
The end zone of the default layout leaves the room those three lines
need at that font, so a target is not squeezed by the drawing itself.
The setting still rules it: a smaller zone shrinks the text again.
tst_cabletarget checks the box is drawn three lines tall at the font
of the drawing, and that the default zone leaves that room.
The number of a wire was written from its mark towards the terminal
without any regard for the room left: a colour code like 'gnge' ran
into the drawing of the terminal. The length of the wires setting
moves the mark, but every project has to be tuned to its longest
number by hand, and a short length leaves no room at all.
Shrink the font while the number is longer than the room between the
mark and the terminal, and clip away what still does not fit even at
the smallest size, so a number never crosses into the terminal -- the
wire length and the font stay the settings to make the drawing
pleasant, they are just no longer able to break it.
tst_cabletarget paints the strip with a long number and without any
and checks the two pictures are the same above the bottom of the
terminal: the number is drawn below it or not at all.
The strip graphic fanned the wires out again after the cable, which
shows each core leaving the cable but says nothing about where it is
going -- the far end was unnamed. Keep the bundle together at the end
now: a short stub and a box with the Installation, Location and Label
(BMK) of the piece the cable lands on, the same three fields the cable
list computes for a target (cablelistrows.cpp), so the strip and the
list can never disagree.
The target is the first piece past the strip's own terminals the
wires of the cable land on, in plan order; a report is no arrival
(the cable continues on the linked sheet), several cores on one
piece are one landing, and a cable which lands on nothing but the
strip itself gets no box. The lines shrink to the end zone the
Terminal plan settings give (Cable end length), so the box never
grows past the strip the bounding rect reserved.
RealTerminal::cableTarget() works the whole out: the cable is the one
the wires drawn to the terminal carry, a name typed by hand is
looked up among the cables of the project, and the box is drawn for
the first wire of the cable group. tst_cabletarget checks the value
rule (own strip no target, spare no target, no cable no target) and
that painting with and without a target gives two different
pictures.
