Combobox stops propagation of the keyboard event. Go with your original but do this in content.mxml
content.addEventListener(KeyboardEvent.KEY_DOWN, handleKeyboard, true); From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of schneiderjim Sent: Monday, November 10, 2008 7:16 AM To: [email protected] Subject: [flexcoders] Re: Custom combobox even propagation I'll admit that I'm not sure you mean by the "capture phase". I can tell you what else I did. In the customer comboxbox constructor, I did add this (pseudo code): public MyComboBox () : void { component = new ComboBox(); component.addEventListener(Keyboard.KEY_DOWN, handleIt); } private function handleIt(event:KeyboardEvent) : void { Alert.show("Here"); } And I did get the keyboard event when I pressed my function key. However, it never seemed to bubble back up to where I really wanted to handle it. I looked at the properties of the keyboard event and bubbling was true. --- In [email protected]<mailto:flexcoders%40yahoogroups.com>, Alex Harui <[EMAIL PROTECTED]> wrote: > > Try listening in capture phase > > From: [email protected]<mailto:flexcoders%40yahoogroups.com> > [mailto:[email protected]<mailto:flexcoders%40yahoogroups.com>] On Behalf Of schneiderjim > Sent: Sunday, November 09, 2008 4:10 PM > To: [email protected]<mailto:flexcoders%40yahoogroups.com> > Subject: [flexcoders] Re: Custom combobox even propagation > > > Thanks, but I'm not looking to capture "normal" keyboard entries in > the combobox.
