"Professional CMake" book suggest the following:
"Targets should build successfully with or without compiler support for precompiled headers. It
should be considered an optimization, not a requirement. In particular, do not explicitly include a
precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
generated precompile header on the compiler command line instead. This is more portable across
the major compilers and is likely to be easier to maintain. It will also avoid warnings being
generated from certain code checking tools like iwyu (include what you use)."
Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
Wrapping QAction through QObject does not work as QAction class
is a part of QtGui not QtCore, so Py::Object with internal
pointer being null is returned causing a crash later.
Therefore implement fromQAction conversion method.
Support longest key sequence match with user defined delay (configurable
through 'Customize -> Keyboard -> Key sequence delay').
Support user defined priority to resolve shortcut conflict through
'Customize -> Keyboard')
Add 'All' category in 'Customize -> Keyboard' to list all command and
showing their shortcuts
Unify macro command shortcut setting (BaseApp/Preferences/Shortcut).
* On lines where the variable type is obvious from inspection, avoid repeating the type using auto.
* When possible use a ranged for loop instead of begin() and end() iterators
