Theoretically, yes. Both LoadVars & XML both have a getBytesLoaded &
getBytesTotal. However, in practice, neither took long enough to actually
justify the time in creating a preloader for them. I'd be lucky to even get
it to show a percentage.
Therefore, you're better of just showing a "loading" progress bar,
(ProgressBar.indeterminate = true):
- show the progress bar
- 1 frame later, load your XML
- when the XML arrives, update your progress bar to done
- 2 seconds later, kill the progress bar
People can argue that for LoadVars & XML calls to files larger than 200k,
it's work it, but to me, people who think Flash can parse such loads without
locking the computer are the types of people who are well aware of what they
are doing (parsing data across frames to prevent Flash locking up) and thus
already know how to create progress bars.
The common use case is not them, however, most are in the less than 100k
range.

Subject: [Flashcoders] preload loadvar xml return
I am doing a loadVars call to a php file, that then returns a bunch of xml.
Is it possible to show a preloader for this load?
var catalog_xml:XML = new XML();
catalog_xml.ignoreWhite = true;
catalog_xml.onLoad = function(success:Boolean) {
if (success) {
} else {
}
sendAndLoad("catalog.php", catalog_xml);
Thanks
