Fixes: Maintaining schemas is difficult and error-prone
- Facilitate easy schemas add, remove, change, etc.
- Remove 14 files containing approx 2,190 lines of if/else code and data
- Place data in one file (UnitsSchemasData.h) using a normalized structure (including special functions)
- Isolate and simplify data operations (code)
- Remove schemas enum to keep data independent of code
- Separate responsibilities: Specifications, data, schemas, schema
- Add schema data 'isDefault'
- Add schema data name
- Prefer algorithms to raw loops
- Add schemas unit tests
- Tweak quantity unit tests
==============================================
Problem:
When the value set is a double, a new Quantity is created, which does not follow
the previously configured format (setDecimals).
Solution:
To copy the old format to the newly created quantity.
* Constructor of QFontDatabase is deprecated, use static functions instead
* Fix QuantitySpinBox::selectNumber()
* Fix InputField::selectNumber()
* Make InputField::fixup() compatible with Qt6
* QFont::setWeight requires an enum now
* QInputEvent reuires a pointing device now
* QAbstractItemView::viewOptions() has been renamed to QAbstractItemView::initViewItemOption()
* Explicitly include some missing headers
* Use 'static const char*' for XPM icon
* Skip template parameters for qMakePair
* Constructor of QFileInfo is marked as 'explicit' now
* QString::fromLatin1() also accepts a QByteArray
* QDateTime::fromTime_t() is deprecated in Qt5 and has been removed in Qt6. Use QDateTime::fromSecsSinceEpoch()
* QDateTime::toTime_t() is deprecated in Qt5 and has been removed in Qt6. Use QDateTime::toSecsSinceEpoch()
* QApplication::globalStrut() is deprecated. Don't use it any more.
* QWidget::isTopLevel() is deprecated, use QWidget::isWindow()
* On lines where the variable type is obvious from inspection, avoid repeating the type using auto.
* When possible use a ranged for loop instead of begin() and end() iterators
* Use multi-arg instead [-Wclazy-qstring-arg]
* Use an empty QLatin1String instead of an empty QStringLiteral [-Wclazy-empty-qstringliteral]
* getter Gui::ProgressBar::canAbort possibly mismarked as a slot [-Wclazy-const-signal-or-slot]
* Missing emit keyword on signal call [-Wclazy-incorrect-emit]
