/** @class wxPGEditor

    Base class for custom wxPropertyGrid editors.

    @remarks
    - Names of builtin property editors are: TextCtrl, Choice,
      ComboBox, CheckBox, TextCtrlAndButton, and ChoiceAndButton. Additional
      editors include SpinCtrl and DatePickerCtrl, but using them requires
      calling wxPropertyGrid::RegisterAdditionalEditors() prior use.

    - Pointer to builtin editor is available as wxPGEditor_EditorName
      (eg. wxPGEditor_TextCtrl).

    - To add new editor you need to register it first using static function
      wxPropertyGrid::RegisterEditorClass(), with code like this:
        @code
            wxPGEditor *editorPointer = wxPropertyGrid::RegisterEditorClass(
                                            new MyEditorClass(), "MyEditor");
        @endcode
      After that, wxPropertyGrid will take ownership of the given object, but
      you should still store editorPointer somewhere, so you can pass it to
      wxPGProperty::SetEditor(), or return it from
      wxPGEditor::DoGetEditorClass().

          events. Instead, all events from control are now automatically
          forwarded to wxPGEditor::OnEvent() and wxPGProperty::OnEvent().
