set to true won't be used as a native menubar (e.g, the menubar at
the top of the main screen on \macos).
\value AA_MacDontSwapCtrlAndMeta On \macos by default, Qt swaps the
Control and Meta (Command) keys (i.e., whenever Control is pressed, Qt
sends Meta, and whenever Meta is pressed Control is sent). When this
attribute is true, Qt will not do the flip. \l QKeySequence::StandardKey
will also flip accordingly (i.e., QKeySequence::Copy will be
Command+C on the keyboard regardless of the value set, though what is output for
QKeySequence::toString() will be different).
\value AA_MacDontSwapCtrlAndMeta Keyboard shortcuts on \macos are typically
based on the Command (or Cmd) keyboard modifier, represented by
the ⌘ symbol. For example, the 'Copy' action is Command+C (⌘+C).
To ease cross platform development Qt will by default remap Command
to the Qt::ControlModifier, to align with other platforms. This
allows creating keyboard shortcuts such as "Ctrl+J", which on
\macos will then map to Command+J, as expected by \macos users. The
actual Control (or Ctrl) modifier on \macos, represented by ⌃, is
mapped to Qt::MetaModifier.
When this attribute is true Qt will not do the remapping, and pressing
the Command modifier will result in Qt::MetaModifier, while pressing
the Control modifier will result in Qt::ControlModifier.
Note that the \l QKeySequence::StandardKey sequences will always be
based on the same modifier (i.e., QKeySequence::Copy will be
Command+C regardless of the value set), but what is output for
QKeySequence::toString() will be different.
\value AA_Use96Dpi Assume the screen has a resolution of 96 DPI rather
than using the OS-provided resolution. This will cause font rendering
