refactor: Remove usage of QT_IMPLICIT_QCHAR_CONSTRUCTION#1058
Merged
Conversation
The macro `QT_IMPLICIT_QCHAR_CONSTRUCTION` allows converting an integer into a QChar. Starting with 6.0, the default behaviour of Qt is to only allow constructing a QChar from an integer explicitly, but until 6.8, above macro allowed the implicit conversion. Qt 6.8 removes the macro, requiring explicitly calling a QChar constructor when creating a QChar from an integer.

Since Qt 6.0, the macro
QT_IMPLICIT_QCHAR_CONSTRUCTIONwas necessary to allow implicit conversion frominttoQChar. Qt 6.8 removes this macro, making the default behaviour mandatory, i.e. call theQCharconstructor with anintto get aQChar.This affects Linux and Windows who make use of this macro; removing the macro reverts to the default since 6.0, so this change is fully backwards compatible.
Qt5 never had the macro (it was introduced to ease the transition from Qt5 to Qt6), therefore nothing changes there either.
Tested on Arch Linux with Qt 6.7.2, 6.8beta3, and 5.15.14.
Fixes #1055
