Re: Download, IE7 Download Blocker
I know in IE8 there is a security setting that can be turned off to remove this feature as they would probably call it. Unfortunately that will require all of your users to make sure they turn this setting off. What I have done to get around this is to return the URL to the user and place it in a DialogBox in an anchor allowing the user to click it and the browser will download it as expected. This is unfortunately a nuance for your users but its better than the download being blocked. Hope that helps, Pat On Feb 18, 10:15 pm, Geoffrey Wiseman geoffrey.wise...@gmail.com wrote: I have a GWT application that uses GWT-RPC to send data back and forth to the server.

Re: Download, IE7 Download Blocker
Here's some code. Perhaps this or a modification should be included in
gwt itself.
There are a few problems with downloading files.
1) IE doesn't always let you open a file download dialog. It will on
some machines, others it won't.
2) Users double click. Prevent this!
3) When opening a window from javascript you want to test whether the
window has been blocked.
You'll have to adjust the code below as it's got some things specific
to our codebase, but it gives you the general idea.
public void download(String title, ClientFile file){
if (Browser.isInternetExplorer()) {
new FileResultsDialog(Download, file).show();
return;
}
if (!PopupDetectingWindow.open(file.getURL(), _blank, )) {
// show HUGE pop-up blocked message.
controller
.getCurrentPage()
.showErrorMessage(
Your download was
blocked! Please enable popups for this site.
This is usually done in a small toolbar just above this sites window.
To test, just click download again.);
}
public class PopupDetectingWindow {
/**
* Opens a new browser window. The name and features arguments
are
* specified a href=
* 'http://developer.mozilla.org/en/docs/DOM:window.open'here/a.
*
* @param url
*the URL that the new window will display
* @param name
*the name of the window (e.g. _blank)
* @param features
*the features to be enabled/disabled on this window
* @return whether or not the popup was opened
*/
public static native boolean open(String url, String name, String
features) /*-{
var mine = $wnd.open(url, name, features);
if( mine ) return true;
return false;
}-*/;
}
in our file results dialog (just a popuppanel):
ExternalHyperlink externalHyperlink = new
ExternalHyperlink(file.getName(), file.getURL());
headerPanel.addLink(externalHyperlink);
Hope that helps!
