DolphinQt2: Add missing Q_OBJECT macro to all QObject-related classes missing it Without this macro, if any signals or slots were attempted to be used, they wouldn't work; neither would various other features of the Qt meta-object system. This can also lead to weird behavior in other circumstances. Qt's documentation specifically states: "Therefore, we strongly recommend that all subclasses of QObject use the Q_OBJECT macro regardless of whether or not they actually use signals, slots, and properties." on its page for "The Meta-Object System", which can be seen here: https://doc.qt.io/qt-5/metaobjects.html Let's opt for "always do the right thing", and keep the code extensible for the future and not have random things blow up on us. 2018-05-13 20:16:20 +00:00			`Q_OBJECT`

DolphinQt: Replace QStringLiteral with alternatives where applicable 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. 2019-07-30 11:57:06 +00:00			`explicit ElidedButton(const QString& text = {}, Qt::TextElideMode elide_mode = Qt::ElideRight);`
