Hi,
I'd like to create a link to separate external page, eg.
"http://www.eclipse.org/" in my RAP app.
What's the best way to do it?
I tried Link widget, but it seems to be just a widget, that still needs
some SelectionListener to really do the action.
I also tried RWT.getResponse() setHeader("Location", ...),
setRedirect(...) things but without success...
Maybe there is some simple way to just render some html like <a
href="http://..."> but I can't find it...
thanks,
Jacek

RWT provides the ExternalBrowser widget for this:
Link link = new Link( parent, SWT.NONE );
link.setText( "<a>Open URL in external browser window</a>" );
link.addSelectionListener( new SelectionAdapter() {
public void widgetSelected( SelectionEvent e ) {
int style = ExternalBrowser.LOCATION_BAR
| ExternalBrowser.NAVIGATION_BAR
| ExternalBrowser.STATUS;
String url = "http://www.eclipse.org/rap";
ExternalBrowser.open( "someId", url, style );
};
} );

Right, the Link widget is an SWT widget and must also work in a desktop
application, where it is not always clear which program to use to for
URLs of a certain type.

RAP doesn't allow to smuggle HTTP code through the SWT API, also for
security reasons. If you use this pattern more often, you could easily
wrap the above code in a utility method.
