If anyone has a solution that doesn't involve JavaScript in the html wrapper I'd love to hear it...
The problem is, Internet Explorer interprets control-key sequences (such as ctrl-r which reloads the browser window) regardless of whether your flex app captures the keystrokes or not, regardless of whether you setFocus() or not. The keystrokes still bubble to the browser. I have tested this both in Firefox and IE7, in Firefox the swf captures the control sequences without disturbing the browser, in IE7 the swf also captures the control sequences, but the browser also reacts to them which can be disastrous from the perspective of the application. This note from Adobe makes me think they have not come up with a simple fix for this yet: http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Book_Parts&file=events_054_21.html The only solution right now seems to be using JS in the wrapper to modify the browser behavior. Here are the related leads I've found so far: http://santrajan.blogspot.com/2007/03/cross-browser-keyboard-handler.html http://www.colettas.org/?p=69 I'd be happy to hear if anyone else has a better solution. --- In [email protected], "Michael Klishin" <[EMAIL PROTECTED]> wrote: > > From my experience setFocus helps in your case, just use it in > creationComplete handler of parent container (whatever it is) or component > root tag (which happens to be parent container as well) > > On 11/01/07, Lieven Cardoen <[EMAIL PROTECTED]> wrote: > > > > In Application is seems to work once with this.setFocus(), but then it > > doesn't work anymore.
