[flexcoders] Re: looping through xml (newbie question)
Thanks for this, I ended up stripping out the namespaces instead as I don't need them (and I couldn't actually make it work), but it's a big help to know it was the namespaces creating the problem and if I do need them in the future I know what I need to read up on.

Turns out it was my fault entirely, I hadn't checked the xml code properly and assumed it was supposed to give me three vertically stacked staves but it was actually showing them horizontally.

[flexcoders] looping through xml (newbie question)
Hi, I'm trying to loop through my xml, but I'm having some problems. I thought this would give me all the line nodes, but it's empty: var xmlLines:XMLList = myXmlList..Line; Is that the right way to go about it, or is there another way? Xml code is below.

[flexcoders] Displaying UIComponents vertically
Hi,
I'm having trouble with the layout of the musical score I'm
displaying. It's generated from an xml file and I want the staves to
be placed on top of each other but I can't make it work. I have a
class which draws out the lines and the notes on it, so I instantiate
that class, create the lines and notes, then create a UIComponent to
add it to. There's three staves, so I do this for all three, then I
add them all to a VBox which I display. I thought this would mean
they'd be stacked on top of each other, but they're horizontally
placed (the second two a little bit lower than the first for some
reason). I'm assuming I'm missing something really obvious, so I'd be
grateful if anyone could point me in the right direction.
Here's the code:
?xml version=1.0 encoding=utf-8?

[flexcoders] newbie question - call to actionscript class
Hello,
I'm brand new to Flex so I'm sure this is a very stupid question, but
hopefully someone will be able to help.
My ultimate goal is to take an xaml file with a musical score and
convert it to flex, but to start with I've hardcoded a score (or
rather some score elements) in an actionscript class and I'm trying
to call it from my main application file. When I debug I can see that
it does get called, however nothing gets drawn on screen. I first did
the hardcoded score in a project on its own, so I know that the score
should be able to be displayed.
Here's the code:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute initialize=initializeHandler()
mx:Script
![CDATA[
import test.DrawNotes;
public var myXmlList:XMLList;
private function initializeHandler():void
{
myXmlList = scoreXml.children();
// loop through the xml here and call
the relevant functions in DrawNotes
var notes:DrawNotes = new DrawNotes();
}
]]
/mx:Script
mx:XML id=scoreXml source=scoreCanvas.xml /
/mx:Application
Does anyone know what I'm doing wrong?
Many thanks,
Annelie
[flexcoders] Re: newbie question - call to actionscript class
I should probably have commented out that bit of code, it's not the
xml I'm having problems with now (well, I have, but I'll get to those
questions later). I thought that by calling my actionscript class,
var notes:DrawNotes = new DrawNotes();, that would display my hard
coded score on screen? I was going to loop through the xml later to
go draw every specific element but for now I'm just trying to draw
anything. Do I need to connect that to a visual element?
Cheers,
Annelie

[flexcoders] Re: newbie question - call to actionscript class
I tried addChild(notes); but that threw an error (Error #1034: Type
Coercion failed: cannot convert test::drawno...@7218ca1 to
mx.core.IUIComponent.). I googled a bit and it seems like you have to
make it into a UIComponent first. I tried this:
var uic:UIComponent = new UIComponent;
uic.addChild(notes);
This doesn't do anything though, so maybe my actionscript code is
wrong. I thought notes would be a Sprite, but maybe I need to do
something more? Here's the actionscript class:
package test
{
import assets.Note;
import flash.display.Sprite;
import flash.text.*;
public class DrawNotes extends Sprite
{
[Embed(source=HELSINKI.TTF, fontFamily=HELSINKI)]
private var embeddedFont:String;
private var note1:Note;
public function DrawNotes()
{
super();
// I've removed it as it would make the code
too long, but this calls a function that creates a textfield with the
music notes
createTextField(17,
AntiAliasType.NORMAL, , 63, 53);
note1 = new Note();
addChild(note1);
}
}
}
Cheers,
Annelie
