Strange but it compile now on Debian Buster chroot and I don't understand why it's compile without this comment on Ubuntu with Qt 5.9..
Thanks.

Re: fix deprecated warning int QWheelEvent::delta() break macOS build

If I dont want to see #pragma messages warnings when I compile for packaging?

QMAKE_CXXFLAGS_WARN_ON += -Wunknown-pragmas
or
QMAKE_CXXFLAGS_WARN_ON += -Wno-unknown-pragmas

not help...

It irritates me to see them, or remove this #prama and keep @TODO?

Re: fix deprecated warning int QWheelEvent::delta() break macOS build

i will look for a solution

Re: fix deprecated warning int QWheelEvent::delta() break macOS build

These messages are useful during development while compiling, but are not useful to be seen when making packages, they pollute real GCC warnings.
