QStringLiterals generate a buffer so that during runtime there's very
little cost to constructing a QString. However, this also means that
duplicated strings cannot be optimized out into a single entry that gets
referenced everywhere, taking up space in the binary.
Rather than use QStringLiteral(""), we can just use QString{} (the
default constructor) to signify the empty string. This gets rid of an
unnecessary string buffer from being created, saving a tiny bit of
space.
While we're at it, we can just use the character overloads of particular
functions when they're available instead of using a QString overload.
The characters in this case are Latin-1 to begin with, so we can just
specify the characters as QLatin1Char instances to use those overloads.
These will automatically convert to QChar if needed, so this is safe.
Avoids dragging in IniFile, EXI device and SI device headers in this header which is
quite widely used throughout the codebase.
This also uncovered a few cases where indirect inclusions were being
relied upon, which this also fixes.
This changes the Host Input Authority and Golf Mode checkboxes into a
set of radio buttons, consisting of Fair Input Delay, Host Input
Authority, and Golf Mode. This represents the 3 network modes we have.
Although Golf Mode is just an extension of Host Input Authority, it's
more logical to the user to present it as a separate option, rather
than enabling the Golf Mode checkbox only when Host Input Authority is
enabled. This also eliminates the need to first enable Host Input
Authority before Golf Mode can be enabled.
This also adds tooltips to provide brief descriptions of the options,
as well as reintroducing tooltips that were previously removed.
This is an extension of host input authority that allows switching the
host (who has zero latency) on the fly, at the further expense of
everyone else's latency. This is useful for turn-based games where the
latency of players not on their turn doesn't matter.
To become the so-called golfer, the player simply presses a hotkey.
When the host is the golfer, latency is identical to normal host input
authority.
Calling deleteLater in MainWindow's destructor doesn't work, as the
event loop will stop before it gets around to deleting these dialogs.
Seeing as this is a QObject destructor, we should already be on the
event loop anyways, so simply using delete should be safe.
