Getting Started
Useful Reading
Information about the changes between Qt4 and Qt5 can be found in the dist/changes-5.x of each submodule
Changes regarding changes to kdelibs can be found at kdelibs/KDE5PORTING.html
Other Changes
Qt Keywords
KDE Frameworks now enforces -DQT_NO_KEYWORDS
This means the macros Qt without the Q_ 'namespace' will not work.
This includes "foreach" "emit", "signals", and "slots". They should be replaced by Q_FOREACH, Q_EMIT, 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))
- QLiteralString for string creation i.e QIcon::fromTheme(QLiteralString("document-new"));
- tr() for translatable strings in frameworks that cannot use i18n
- i18n for translatable strings in frameworks that can use i18n
