Hello,

Google Summer of Code 2010 was announced recently. Will EmWeb (try to)
participate this year?

Maybe we can start a brainstorm here for new ideas. The ideas for GSoC
2009 (sadly EmWeb got no slots) are still there:

http://redmine.webtoolkit.eu/wiki/wt/Ideas_for_Google_SoC

* WebKit integration

A first, very pedestrian approach, is available from
http://gitorious.org/wtdesktop

This idea is to incorporate WebKit into Wt. The level of integration
may evolve over time, as are the possible applications.

The first step is to combine WebKit with the built-in httpd to provide
a desktop application using Wt. This could be useful for distributing
an off-line version of a Wt application or during development. The
webkit would be configured to act as a single application (instead of
as a general purpose browser).

The second level is to allow introspection of the DOM inside WebKit
from a Wt application session. This could become the basis for an
automated testing framework which verifies that the widget tree and
the DOM tree are in sync. By querying the DOM for information on the
location and CSS properties of widgets, it can be checked that the
application works properly. By allowing for events to be simulated on
the DOM tree, the application can be checked for correct event
handling.

The third level is to by-pass the HTML/JavaScript and HTTP protocol
for certain rendering steps. For example, a new WPaintDevice could be
developed which paints directly instead of encoding it first as SVG or
HTML Canvas5 JavaScript. This would allow significant speedups for
vector graphics.

Required expertise: Good C++ knowledge, knowledge of or willing to
learn the CMake build system, familiarity with GTK or Qt application
development.


* Widget Set mode

Since some months, Wt includes a so-called widget-set mode. In this
mode, a Wt application does not take responsibility to render the
entire user interface, but only selected <div>'s. The Wt application
is loaded as a JavaScript library, which then renders into these
<div>'s, which then correspond to a set of "top-level" widgets. Any of
%Wt's features may be used inside such a widget, including portable
vector graphics.

This would allow a Wt application to also expose a JavaScript API,
such as for example Google Maps, but this has not yet been provided.
To provide support for this in the Wt library, it would require that a
Wt application can extend its JavaScript object with JavaScript
methods that map onto C++ methods, which assumes a system that helps
as much as possible to convert between JavaScript objects and C++ data
structures (for example based on maps).
