Live spelling check in TcxTRichViewEdit

In applications using DxSpellChecker, it is assumed that live spelling is performed only in the focused component.

If you use TcxTRichViewEdit component, it will be checked automatically when focused, if RvDxSpellChecker.CheckAsYouTypeOptions.Active = True.

You can assign TRVAPopupMenu component to RichViewEdit1.PopupMenu, however, TcxTRichViewEdit can display a popup menu with live spelling options even without it.

Live spelling check in TRichViewEdit (and TSRichViewEdit)

TRichViewEdit, process OnEnter and OnExit:

OnEnter: 
  RvDxSpellChecker1.CheckAsYouTypeOptions.Active := False; 
  RvDxSpellChecker1.UpdateRules; 
  RichViewEdit1.StartLiveSpelling;
