Hey all, We have uploaded Wt 2.2.1 was uploaded to sourceforge.
As usual, this release is a mix of bug fixes, improvements, and new features. All changes were recorded in the Changelog. The most note-worthy new additions: - The WAbstractItemModel interface and the WStandardItemModel implementation now support hierarchical models. This may break existing code if you have implemented your own model or implemented your own view class (see the release notes [http://www.webtoolkit.eu/wt/doc/reference/html/Releasenotes.html] for details). - The WTreeView widget uses the new WAbstractItemModel to implement an MVC-based tree (table) view component. Learning from existing experience with WTreeTable and Ext::TableView, this widget has been designed to be able to deal with large models. Not only is data loaded incrementally as you expand nodes, also only visible nodes are loaded into the browser (with some margin). Invisible nodes are stubbed and replaced with real content as needed. In this way we support arbitrarily large models with constant memory usage both in the browser and the server, and a responsive user interface. See the new treeview example for how to use it (this example is not yet available online). Development on this widget is ongoing. Most notably, there is not yet any support for editing the underlying model, and no general support for delegates which allow you to have more control of how cell contents should be rendered. - A widgetgallery example was added that demos most of the widgets and features in Wt. - WSubMenuItem extends WMenuItem to hold a sub menu (see the widget gallery example for its usage).
