There is not an <mx:Breadcrumb> component in Flex ..
it's behavior you would have to bake
into your own application. From a UI point of view,
the <mx:LinkBar /> tag might be a good
starting point for you to contain a Breadcrumb trail
in.
Think about how you might encapsulate a link bar component;
your link bar has a
data provider that is the links to be displayed. You
could encapsulate that
data provider, and expose methods on your BreadCrumb
component that
encapsulate the array with methods such as descend() or
ascend() that push
or pop links onto the link bar data provider, and switch
the view accordingly.
If you have a basic understanding of how to extend Flex
component, spend some
time mucking around with the Link Bar, and think about what
you'd want a
public API to look like, it shouldn't be a great deal of
work for you to be able
to create a custom component:
<magic:BreadCrumbs id="trail" />
and then be able to perform ActionScript calls such
as:
trail.descend( "anchorName" ); // push anchorName on the
breadcrumb trail for current view
trail.ascend(); // pop the current anchor off the stack and
toggle back the view
Note that I don't have any source for this (I'm
brainstorming here) and assume
that "magic" is the namespace that I create my custom
component in.
Hopefully I've lifted one corner in this email, and that
you can lift the other three....
Best,
Steven

From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Shahnavaz Alware Sent: 15 June 2005 20:37 To: [email protected] Subject: [flexcoders] Flex Component Hi All, This is a repetition of my last
email. Does Flex provide anything for “Breadcrumb/trail”? Actually I have to
replace the ViewStack implementation by some kind of trailing functionality. So
I am trying to find out how I can achieve the same Viewstack implementation with
multiple PATH to get to the same screen. Any reply would be helpful as I am new
to this Flex UI. Thank
you, Shahn Yahoo! Groups Links
