In kconfigwidgets/src/ktipdialog.cpp the tips are translated using a tr call, but otherwise KConfigWidgets uses KI18n for internationalization. Also translation of tips doesn't currently work with at least some KF5-based applications that use KI18n. Examples are Kig and Parley. Those two tr calls can be changed to i18n calls, but then the calls need to be connected to the correct catalog where the tips are translated. Tested with kconfigwidgets from git master, updated today, 2014-02-08. Reproducible: Always Steps to Reproduce: 1. Use x-test as translation language. 2. Open a KF5-based application that uses Tip of the Day (for example Kig or Parley). 3. Open Tip of the Day window. Actual Results: Tips appear in English. Expected Results: Tips appear in x-test, that is, they have two x characters at the beginning and at the end.
