- there are now XMLUIPanel and XMLUIDialog both inheriting from XMLUIBase
- following dialogs are managed:
- MessageDialog
- NoteDialog
- ConfirmDialog
- FileDialog
- XMLUI creation is now made using xmlui.create(...) instead of instanciating directly XMLUI
- classes must be registed in frontends
- "parent" attribute renamed to "_xmlui_parent" to avoid name conflicts with frontends toolkits
