[news.eclipse.platform.swt] Re: Browser widget on Linux (BUG?)

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

A simpler approach that may work is to asyncExec() it in the main thread
rather than using another thread.  This would look like:

browser.addStatusTextListener(new StatusTextListener(){
    public void changed(StatusTextEvent event) {
        browser.getDisplay().asyncExec(new Runnable() {
            public void run() {
                if (browser.isDisposed()) return;
                browser.execute(script);
            }
        });
    }
});
