Re: Applet internet explorer
Thanks for the reply Bryan.
The problem I was having is different.
I fixed it setting my HTML object to "" - html.setHTML("");
and then the applet is not loaded anymore.
When I need the applet to be loaded again I set this same HTML to the applet
tag.
Thanks

Is there a way to make the FixedWidthGrid (where is the content of the

Re: Download file
Hi guys, I still couldn't find the right way to create an hyperlink in my web app that makes a download of a file from the server to the client. When you say "You have to create a GWT hyperlink and point it to the resource" What method of the GWT Hyperlink do I use to point this hyperlink to the resource (the file to be downloaded in my server - I know the exactly location path + filename.) I can't find the method that I can use to point to this file. Can abybody give me a little help one more time? thanks again 2009/9/16 Ian Bambury > Please don't post the same question more than once - at least, not in the > same 5 minutes. > Ian > > http://examples.roughian.com > > > 2009/9/16 sathya > > >> I am having same problem in GWT 1.7. >> In my application, I need to download file from server to client.

Re: Download file
Hi chandrahas, thanks for the answer I've been out from work last week. Now I have to create a way to the user of my application make a download of a file that is in the server. I know the exactly location of the file and its name. But I don't understand how to create a link (would be a GWT Hyperlink) that point to my file. I think this way is easier than to create a servlet. Could anybody give me a little help about? thank you guys again 2009/8/25 chandrahas koyari > > There are two general methods to achieve it > 1.
