  49 /** @class wxPGEditor
  50
  51     Base class for custom wxPropertyGrid editors.
  52
  53     @remarks
  54     - Names of builtin property editors are: TextCtrl, Choice,
  55       ComboBox, CheckBox, TextCtrlAndButton, and ChoiceAndButton. Additional
  56       editors include SpinCtrl and DatePickerCtrl, but using them requires
  57       calling wxPropertyGrid::RegisterAdditionalEditors() prior use.
  58
  59     - Pointer to builtin editor is available as wxPGEditor_EditorName
  60       (eg. wxPGEditor_TextCtrl).
  61
  62     - To add new editor you need to register it first using static function
  63       wxPropertyGrid::RegisterEditorClass(), with code like this:
  64         @code
  65             wxPGEditor *editorPointer = wxPropertyGrid::RegisterEditorClass(
  66                                             new MyEditorClass(), "MyEditor");
  67         @endcode
  68       After that, wxPropertyGrid will take ownership of the given object, but
  69       you should still store editorPointer somewhere, so you can pass it to
  70       wxPGProperty::SetEditor(), or return it from
  71       wxPGEditor::DoGetEditorClass().

 119           events. Instead, all events from control are now automatically
