I have gone through DataGrid and List classes, both of them listen for focusInHandler and override this method to add a listener for "keyFocusChange" event. and then in the handler, do processing manually for itemrenderer. My question is, do I have to do it manually for my component which has other components which receive focus when they are on stage. (i.e. My component is a composite of Button, TextInput and a TextArea, do I have to manage focus manually or FocusManager can take care of it, I read that there can be multiple instances of FocusManager in an application, when it can be useful ?). Could you please point me to some documentation/presentation etc.
One more question, when to use IFocusManagerComponent and when to use IFocusManager. (I have developed same component in Flash also. I don't have to manage focus manually, it was taken care by FocusManager itself) Thank you -- Chetan www.riageeks.com --- In [email protected], Alex Harui <aha...@...> wrote: > > In Flex components can be comprised of sub-components. The outermost component, which is most often the thing that you think of as the component and would normally set focus to (like a DataGrid) is an IFocusManagerComponent with focusEnabled=true. All child sub- components that are IFocusManagerComponents have focusEnabled=false. When the DataGrid wants to pass focus to child cell editors, it intercepts the keyFocusChange event and handles tabbing itself. > > Other components are "containers" and do not directly receive focus and have tabChildren=true and tabEnabled=false > > Alex Harui > Flex SDK Developer > Adobe Systems Inc.<http://www.adobe.com/> > Blog: http://blogs.adobe.com/aharui > > From: [email protected] [mailto:[email protected]] On Behalf Of cksachdev > Sent: Sunday, February 08, 2009 9:14 PM > To: [email protected] > Subject: [flexcomponents] Problem with Keyboard navigation in custom component > > > Hi to all, > > I have developed a few set of custom components and I am facing > problem with tab navigation.
