Other Changes

Qt Keywords

KDE Frameworks now enforces -DQT_NO_SIGNALS_SLOTS_KEYWORDS

This means the "signals" and "slots" keywords will not work. They should be replaced by Q_SIGNALS and Q_SLOTS respectively.

Strings

In Frameworks 5 any string on its own such as "foo" will not be automatically converted to a QString. Instead, you should use one of:

  • QLatin1String() for string comparisons i.e (if myString == QLatin1String("SomeText))
  • QStringLiteral for string creation i.e QIcon::fromTheme(QStringLiteral("document-new"));
  • tr() for translatable strings in frameworks that cannot use i18n
  • i18n for translatable strings in frameworks that can use i18n
