Re: ImageResource, Sprites and Data: URL
Oops! I think I replied to the individuals last time ;) Here's a summary: @DoNotEmbed is only for DataResource and not for any ResourcePrototype. Looked at the code of ImageResourceGenerator which says forceInline = false always, without caring about DoNotEmbed. IMHO, a simple change to this effect will be very useful. ClientBundle.enableInlining was the only option that worked, but sadly, it disables at a global level.

ImageResource, Sprites and Data: URL
Hi, Is there any option to force use the generated sprite image instead of the data:image/* URL? As I understand, the only reason to use data: URL is to avoid extra connection to the server. However, if an sprite has been created (and my sprite has around 150 images combined in), I'd prefer using that image. One extra connection for this, IMHO - specially in my case, is better than dumping in all 400KB of data in the HTML image that increases the payload and initial load-time by a huge amount (my basic HTML is only a few KBs, not even 100's of KBs) Happy Hacking, Gaurav Vaish http://www.mastergaurav.com -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Place image in object, send object over rpc, use hibernate to update database
Sending image data over RPC... how do you plan to use this binary data
on the client side?
It's not possible... JavaScript does not have any image-processing
API.
You can do something like this:
- Create the image binary data on the server, and label it with some
unique ID (store in memory, filesystem, db wherever).
- Create a servlet, say ServeImageServlet that will do something like
this
doGet(...) {
String id = request.getParameter(imageID);
InputStream input = huntForImageUsingID(id);
response.setContentType(image/png); // or jpg, gif...
OutputStream output = response.getOutputStream();
//copy all data from input to output
}
- In your RPC response, just send the URL.
Assuming that the servlet is mapped to /img, the URL can be
something like /img?imageID=abcd
- In the GWT app, use this URL to create a new Image(url)

Re: How to show the contents from a checkbox in a separate panel
Hi Samuel, Here's an outline of solution that can you may want to use (frankly speaking, I haven't gone in depth of your code): 1. Create an ArrayListCheckbox of all checkboxes 2. Add a ValueChangeChandler (if interested in only value) or ClickHandler (if you want instance reference as well). No specific preference in this case... feel free to choose anyone. 3. To get all checkboxes selected, iterate through all the checkboxes in the ArrayList created earlier and use getValue() method to get if it is selected or not. -- Happy Hacking, Gaurav Vaish http://www.mastergaurav.com On Nov 20, 11:55 pm, joelsamuel marc.bleic...@gmail.com wrote: Background: Hello I am quite new to GWT and Java.

Re: shared src folder and default constructor
Any class that participates in GWT-RPC should have a default constructor which is invoked during deserialization (on either size - server and client). The initialization code in your constructor is never trashed. It may happen that based on the data transferred, the values would get overwritten.
