I have something working, there might be a simplier
solution but that's all I have (see
attachment) ;))

From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Brooks Andrus Sent: mercredi 10 août 2005 10:34 To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Re: selectedItem in a list shows an icon Does the list component
in Flex not have setPropertiesAt() ? This method of the list takes two
arguments: 1)
the index
of the row in the list you want to modify (listen for a change event and then
check the selectedIndex property of the
list). 2)
a style
object which allows 2 properties of the row in question to be set-the
backgroundColor (hex value) and an icon (in Flash the icon properties value
would be equivalent to the linkage id of a MovieClip in the library you wished
to use as an icon). I hope this helps-I'm a
Flash guy who lurks on the flexcoders list in a lame attempt to keep abreast of
the technology. Regards, Brooks From:
Is there an example you can show me...I'm not quite sure
