Picking a sheet (folio) background colour in the diagram editor was lost
on every restart. Diagram::background_color is a static initialised to
white and PaletteGraphicsView's s_custom_bg a static bool, and neither
was ever written anywhere -- Diagram::toXml() carries no colour attribute
either -- so closing and reopening a project always came back on the
default and the choice had to be made again.
Store it in QSettings under diagrameditor/sheet_background_* as a pair of
values rather than one: the colour, and whether it was picked explicitly.
Both halves are needed. "#ffffff, follow the system" and "#ffffff, always
white" are the same colour and two behaviours -- the first is what the
views invert on a dark palette -- so keeping only the colour would
silently turn one into the other on the next start, which is the reported
problem one step removed.
The colour is written as HexRgb on purpose. The SVG export gives
Diagram::background_color an alpha of 0 to render a transparent
background and never puts it back, and that transient value must not be
persisted as a permanently transparent sheet.
Applied from main() after the headless export and scripting branch -- those
return before reaching it and must keep rendering on plain white, the rule
ProjectPrintWindow already enforces for printing -- and before QETApp is
constructed, since that constructor already loads the projects given on
the command line. The GUI export dialog is left alone: it renders through
drawBackground(), so what you see is what you export, as it already was
within a session.
Saved at the moment the colour is applied rather than at shutdown, so
neither the print window's temporary white nor the SVG export's alpha can
reach it. The button's constructor now mirrors the stored state instead of
always claiming "system colour", and the "recently used" list is stored
alongside it.
Covered by tst_sheetbackgroundsetting, which pins the custom flag and the
dropped alpha -- the two rules a single stored colour would lose.
A script reaches the whole project and, through the export calls, the
filesystem. That is a capability most people installing an electrical CAD
program never asked for, and leaving it on by default hands it to them
anyway. So QET_HAS_SCRIPTING builds now ship with it switched off.
QetSettings::scriptingEnabled() is the single answer, read by all three
places that need it, with QET_ENABLE_SCRIPTING=1 overriding the stored
value. The override is not decoration: a CI job or a batch run has no
dialog to tick, and a machine whose HOME is created fresh for each run has
nowhere to keep the setting either. It beats a stored "false" on purpose,
so a box unticked once cannot lock a build server out of --run for good.
Only the exact value "1" counts.
--run refuses with exit 3 and a message naming both ways in.
Projet > Exécuter un script... asks once, and turns the setting on if
the answer is yes. Asking beats grey: a disabled menu
entry says something exists and nothing about how to have
it, and this is the pattern people already know from
macro security in office software.
Configurer QElectroTech > Général > Projets has the checkbox, for
turning it back off. While the environment forces
scripting on, the box is disabled and says why, and
applyConf() then leaves the stored value alone rather
than quietly overwriting it.
runOnProject() checks as well, after both callers have. It is the one
function that actually evaluates JavaScript, so it is the one place a
future caller cannot forget to ask; the callers check first only to give a
better answer than it can.
Verified on the built binary, all four states, with an isolated HOME:
stored env result
absent - refused, exit 3
true - script runs, exit 0
false - refused, exit 3
false 1 script runs, exit 0
tst_scriptingsetting covers the same matrix hermetically, in its own
QSettings scope, and was mutation-checked: flipping the default to true
turns defaultsToOff() red.
