Description
When trying to use lupdate to update translations in a source file that also includes an enum class with the underlying type specified, lupdate fails to recognize the context when using e.g. `tr()` inside of a class method of a class inheriting from QObject and using the Q_OBJECT macro.
Steps to reproduce:
1) Extract attached sample project translation-with-enum-class.zip
2) In the project directory, build the project:
$ ~/development/git/qt5/qtbase/bin/qmake $ make clang++ -c -pipe -g -std=gnu++1z -Wall -Wextra -fPIC -D_REENTRANT -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I. -I/home/michi/development/git/qt5/qtbase/include -I/home/michi/development/git/qt5/qtbase/include/QtWidgets -I/home/michi/ development/git/qt5/qtbase/include/QtGui -I/home/michi/development/git/qt5/qtbase/include/QtCore -I. -I/home/michi/development/git/qt5/qtbase/mkspecs/linux-clang -o main.o main.cpp /home/michi/development/git/qt5/qtbase/bin/lrelease translation-with-enum-class_de_DE.ts -qm .qm/translation-with-enum-class_de_DE.qm Updating '.qm/translation-with-enum-class_de_DE.qm'...

3) In the project directory, try to update the .ts file using lupdate:
$ ~/development/git/qt5/qtbase/bin/lupdate translation-with-enum-class.pro /tmp/translation-with-enum-class/main.cpp:15: tr() cannot be called without context Updating 'translation-with-enum-class_de_DE.ts'... Found 0 source text(s) (0 new and 0 already existing) Kept 1 obsolete entries
Actual result:
As seen above, the the following warning warning is shown and the .ts file with the German translation is not updated:
/tmp/translation-with-enum-class/main.cpp:15: tr() cannot be called without context
Expected result:
No warning, .ts file should be updated.
Further observations:
1) This works just fine when either removing the
enum class MyEnum : int { FIRST, SECOND, THIRD };
or also when not explicitly specifying the underlying type for the enum class, i.e. using this instead:
enum class MyEnum { FIRST, SECOND, THIRD };
2) Issue is reproducible with both, self-compiled qttools dev as of 213a613244cbbccaaf22f969e73d16052254f593 and lupdate from the qt6-l10n-tools 6.6.2-4 package as provided by Debian testing.
3) The issue is not reproducible when using lupdate from Debian's Qt 5 package instead (qttools5-dev-tools 5.15.13-4):
