- Added Splitter::Type so it can be by pixel or by percentage.
- Added Widget::load/saveLayout functions and Widget::onLoad/SaveLayout
events.
- Added LayoutIO interface so we can delegate the serialization of the
layout.
Several refactoring tasks where made:
- Removed the old Widget::id field (JID).
- Renamed Widget::get/setName to get/setId.
- Moved load_widget_from_xmlfile() to app::load_widget and WidgetLoader
class.
- Removed jhook structure & jwidget_add_hook function. Hooks were replaced
subclassing widgets.
- Added InitThemeEvent class and Widget::onInitTheme member function.
