Description
If you use the wrong type for Q_ARG, you will get a list of candidates:
14:27:14: Starting C:\dev\temp\quick-cpp-test-Desktop_Qt_6_2_0_MSVC2019_64bit-Debug\Stuff.exe ...
********* Start testing of Stuff *********
Config: Using QtTest library 6.2.0, Qt 6.2.0 (x86_64-little_endian-llp64 shared (dynamic) debug build; by MSVC 2019), windows 10
PASS : Stuff::initTestCase()
QWARN : Stuff::test_case1() QMetaObject::invokeMethod: No such method WorldMap_QMLTYPE_0::worldMapTilePosToScenePos(QPointF)
Candidates are:
worldMapTilePosToScenePos(QVariant)
FAIL! : Stuff::test_case1() Failed to call worldMapTilePosToScenePos on chooseDestinationWorldMap
C:\dev\temp\quick-cpp-test\tst_stuff.cpp(47) : failure location
PASS : Stuff::cleanupTestCase()
Totals: 2 passed, 1 failed, 0 skipped, 0 blacklisted, 122ms
********* Finished testing of Stuff *********
14:27:14: C:\dev\temp\quick-cpp-test-Desktop_Qt_6_2_0_MSVC2019_64bit-Debug\Stuff.exe exited with code 1
If you make the same mistake with the return type, you get nothing besides a false return value.
The list of candidates should also show the return type, and there should be a warning when only the return type is wrong.
