    Automatically hide word candidate list · 839a0afe
    Jarkko Koivikko authored
    
    This change adds support for automatically hiding word candidate list
    when inactive. This feature includes the following enhancements:
    
    - Added new settings:
      * VirtualKeyboardSettings.wordCandidateList.autoHideDelay
      * VirtualKeyboardSettings.wordCandidateList.alwaysVisible
    - Automatic hiding of word candidate list when inactive and when
      autoHideDelay elapsed.
    - alwaysVisible setting restores the old functionality.
    - Added new signal selectionListsChanged() to input method, allowing
      the input method to dynamically allocate or deallocate selection
      lists.
    - HunspellInputMethod does not allocate selection list when
      dictionary cannot be loaded, or Qt::ImhNoPredictiveText is enabled.
      Also, it will no longer use pre-edit text in this case.
    - OpenWnnInputMethod does not allocate selection list if not needed.
    
    [ChangeLog] Automatically hide word candidate list when inactive.
