preventDefault is only for cancelable events, and KEY_DOWN is not cancelable.
I don't think there's an easy answer, you'll probably have to detect the problem and adjust the scrollposition yourself. From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of itdanny2002 Sent: Wednesday, November 26, 2008 6:13 AM To: [email protected] Subject: [flexcoders] PreventDefault doesn't work An application with only 2 controls ComponentA is a multi-line text. ComponentB is TextInput. I capture PgUp/PgDn and scroll the component. However, when focus on component B, PgUp/PgDn will cause my cursor move to the end or beginning of word together with scrolling. I want to scroll without moving the cursor in textInput. I try to use preventDefault() but not success private function KeyDown(event:KeyboardEvent):void{ if (event.KeyCode == KEYBOARD.PAGEUP) { ...... scroll the page...... } } private function ComponentAKeyDown(event:KeyboardEvent):void{ if (event.KeyCode == KEYBOARD.PAGEUP) { event.preventDefault(); } } It works for other key, but not PgUp, PgDn !! I try to override KeyDownHandler, not ok. Any helps ?
