- Replace Q[TRY]_VERIFY(pointer == 0) by Q[TRY]_VERIFY(!pointer).
- Replace Q[TRY]_VERIFY(smartPointer == 0) by
Q[TRY]_VERIFY(smartPointer.isNull()).
- Replace Q[TRY]_VERIFY(a == b) by Q[TRY]_COMPARE(a, b) and
add casts where necessary. The values will then be logged
should a test fail.
in tests/auto/other, tests/auto/printsupport and tests/auto/xml.
