Nathan,
I don't know if you are just having trouble getting the menu to generate from
XML or just in general. I took the code you provided and it does work. I can
't
get it to work using XML either, but I don't know what a properly formatted
XML document looks like (does it need to start and end with <xml></xml>
respectively?). The path to the XML document would replace "url" in the last
line (loader.load(url);) -- the path would need quotes around it. However I
just
get an output error when I try to use that method instead of the one in lines
11
- 15 provided below.
I found this topice after being thoroughly frustrated with the lack of info
provided by Macromedia about how to implement the menu component,
myself. I watched their intro to components presentation on their website and
had to laugh when they said components were designed to help those who
didn't know much about ActionScript. I know a little, and I can't figure it
out.
Does anyone have a working example of something they did with the menu
component? Something complete with a customized style and actions when
clicking on a menu item. I can't seem to find a click event for a menu item in
the help either.
