/** @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().

- Primary control shall use id wxPG_SUBID1, and secondary (button)
control shall use wxPG_SUBID2.
- Unlike in previous version of wxPropertyGrid, it is no longer
necessary to call wxEvtHandler::Connect() for interesting editor
events. Instead, all events from control are now automatically
forwarded to wxPGEditor::OnEvent() and wxPGProperty::OnEvent().
