That's a great answer especially considering I wasn't exactly sure what I was asking. I think I have two more questions which would finish up this line of questioning for me. (I'm working off the UIComponent API doc also.)
1. If you click on a composite component, it will walk up the parent tree until it finds mouseFocusEnabled = true, and then walk up the tree until it finds focusEnabled = true, and then set the focus to that component? 2. What happens if you have mouseFocusEnabled and tabEnabled both equal false and focusEnabled = true. Then you can set focus through code or by clicking on a child? All of this assumes that mouseEnabled and mouseChildrenEnabled are set correctly. (I'll be honest that I'm a little confused with mouseChildrenEnabled also, but I haven't looked very hard for that yet.) Thanks, - Dan On 11/16/06, Matt Chotin <[EMAIL PROTECTED]> wrote:
From the focus guru: Actually, Flash will remove focus from a textfield when the mouse is clicked outside of the textfield. The Flex FM always tries to make sure something has focus always (generally a good practice for accessibility) so it will not let focus go away unless something else is clicked that is IFocusManagerComponent and has mouseFocusEnabled=true. You have to implement IFocusManagerComponent in order to be a focus candidate from the Flex FM perspective and have focusEnabled=true to actually receive focus. mouseFocusEnabled says whether you want to receive focus via mouse clicks, tabEnabled says whether you want to receive focus from the keyboard. focusEnabled=false is a good way to disable child components like scrollbars that shouldn't receive focus HTH, -Alex ------------------------------ *From:* [email protected] [mailto:[EMAIL PROTECTED] *On Behalf Of *Daniel Freiman *Sent:* Thursday, November 16, 2006 12:18 PM *To:* [email protected] *Subject:* Re: [flexcoders] Understanding the FocusManager There's not any specific question yet. But I foresee two issues. 1. What prompted the question was that I had a UITextField that wasn't losing focus when I clicked on UIComponent. I know this specific example would be guided by the player's focus manager and not mx.Managers.FocusManager, but I thought there might be some interaction between the two managers I could leverage. For now I have a workaround of setting the selection to an off screen object. What I'm worried about is that in Flash 8 this type of problem tended to compound and I actually spent 40% of my time just trying to resolve focus issues because I didn't understand focus when I started writing the program. 2. My second issue is just that I want to make sure I'm using the object properties correctly (focusEnabled, mouseFocusEnabled). From reading the docs, they seem to enable receiving focus events, but set focus to only objects that have mouseFocusEnabled=true? If either of this spark a specific answer, I would appreciate it. If not I'll just wait until I come across a more specific problem. Thanks, - Dan On 11/16/06, *Matt Chotin* <[EMAIL PROTECTED]> wrote: Hi Dan, There aren't any real docs with details on it.
