Re: Web Workers in GWT

Thank you for your input Chris.
Yes I have been looking at the code included in Speedtracer but
without documentation (and the fact that I am a novice GWT developer)
I am having a difficult time figuring out how to the webworker is
being set up and used in Speedtracer. There seems to be a module for
the webworker with various classes representing worker entry points
but I am not sure which would to implement and in what context. In the
xml files of the modules i did notice an <add-linker ...> tag which I
am assuming points to the module that represents the worker. Again, if
anyone could provide a few basic steps to make a simple web worker
work in GWT I would greatly appreciate.

On a general note, I am a bit surprised by the lack of support
available for web workers in gwt, when there is support for other
HTML5 features like local storage, canvas etc. Does anyone know why it
is the case ? Are people not interested in using multi-threading in
GWT or is GWT not a suitable tool for such an application ?
