Hello, I'm working with GWT with the MVP pattern, actually implementing a search results page. The search results are represented by a picture + some info. I created a presenter and a view for a search result (I'll call this little square "thumbnail" for now on), so that I can add it several times to the search results page, and use i...
I have a regular Java application and want to access an GWT RPC endpoint. Any idea how to make this happen?

Hello, we've got a GWT application with a simple search mask displaying the results as a grid. Server side processing time is ok as well as network latency. Client rendering time is ok even on low spec hardware with internet explorer 6 as long as the number of results is not too high (max 100 rows in the grid). We have implemented ...
The opposite of this question: http://stackoverflow.com/questions/138099/how-do-i-add-a-type-to-gwts-serialization-policy-whitelist GWT is adding undesired types to the serialization policy and bloating my JS. How do I trim my GWT whitelist by hand? Or should I at all? For example, if I put the interface List on a GWT RPC service class...

I've been playing around with GWT 2 and I'm finding it quite hard to get the basic page layout that I want. Basically I'm using a DocLayoutPanel where I'm adding a north (header), south (footer), west (navigation), and content area. I'd like the doc panel to take up 90% of the page and centered. That would give a nice 5% margin. Howe...
Hi, In javascript, I'm making an SVG shape and adding a click handler to it like this: var rect = document.createElementNS('http://www.w3.org/2000/svg','rect'); rect.addEventListener('click', myClickHandler, false); it works great.

However, for some reason, GWT does not sem to be used much in the real world. Is there something that is similarly tied into Java (like...
Hi, Can we add a listener for mouse move events on the main document in GWT? I'm not sure how to do this and if whatever I do add will interfere with other parts of GWT (like drag and drop?). In javascript I do this: window.onload = function() { document.onmousemove = function(e) { alert("the mouse was moved!"); }; } ...
