It was already public and used elsewhere, so the new get_background_process()
and its duplicate forward declaration were redundant; Plater.hpp is now untouched.
* build: remove std::move that blocks copy elision
std::move wrapped around a temporary, or around a local being returned,
stops the compiler constructing it in place. Each edit is the fix clang
suggests, which is to delete the std::move call and keep its argument.
Three of the 39 sites save a move, the two return std::move(local) in
Print.cpp and TreeSupport.cpp:2749. The rest are equivalent either way
and match how the codebase already writes this elsewhere.
Clears 39 -Wpessimizing-move warnings.
* build: drop null checks on references and this
A reference cannot be bound to null and this cannot be null, so the
compiler folds these conditions to true and drops the guard. Seven are
if (&bitmap && bitmap.IsOk()), where IsOk() already does the work; two
test this directly. The guarded code runs either way, so removing the
dead operand changes nothing.
Clears 11 -Wundefined-bool-conversion warnings.
New Project and Open Project went through Plater::priv::reset, which
drops ModelObjects but not the Model-level recipe, and never touched
the Design panel's document at all — so the previous design stayed
loaded and its next edit wrote itself into the new project.
A design that has not been committed to the plate has no ModelObjects,
so the project also read as clean: no autosave, and no unsaved-changes
prompt before the reset threw the design away.
* Keep mixed-color filaments intact when the extruder count changes
The extruder-count spinner resized the filament arrays in bulk at the tail,
which is where mixed-color slots live, so a new filament landed behind the
mix and the sidebar skipped a slot number. It now adds and removes one slot
at a time through the same calls the sidebar's +/- buttons use, so a new
slot opens ahead of the mixed tail and a removal renumbers object filament
ids, painted facets, custom g-code and mixed components rather than
clamping them away.
Drops the vector overload of set_num_filaments(), which this leaves without
callers.
Call update_dynamic_filament_list() alongside update_mixed_filament_list() in two places: after editing a mixed filament slot and when the filament count doesn't change (e.g., adding a mixed/virtual slot). This ensures per-feature filament lists reflect the updated blended colour and type without requiring a full filament count change.
The sidebar Mixed Filament list, the extruder icons, the color painting
gizmo and the canvas filament bar now show the same bottom-to-top fade the
Edit Mixed Filament preview shows, custom gradient curves included, instead
of a horizontal fade between the two component colours. Ordinary and vendor
multi-colour filaments are drawn exactly as before.
Mixed-colour slots are virtual and never flushed. Guard auto_calc_flushing_volumes_internal against them as BambuStudio does, and make the flushing dialog's default matrix and the sidebar 'modified' comparison physical-only so the untouched mixed rows no longer count as a user edit and the Re-calculate result matches the physical-only table.
