  • isInitialized() is gone -> if needed, track this in the class itself
  • event(QEvent *) is replaced by triggerableContextAction, performNextAction and performPreviousAction
  • ContainmentActionsSource enum type, getter and setter gone. All containment actions are global by their containment type, so all panels have the same config, all desktop have the same config

Context

  • Plasma::Context has been removed; the Activity DataEngines or KActivity* classes should be used instead.

Corona

  • layoutContainment is now virtual (no actual porting required; it is still a protected slot)
  • importLayout(const KConfigBase &config) was removed in favor of importLayout(const KConfigGroup &config)

  • Removed abstractDialogManager(), the whole class AbstractDialogMager has been removed as well
  • Removed appletMimeType() setAppletMimeType() (not used)
  • Renamed addContainment() to createContainment()

  • Removed releaseVisualFocus()
  • Removed initializeLayout() -> use loadLayout() instead. if then corona will have 0 containments, then call loadDefaultLayout()
