Ahhh HA! I was reading the adobe documentation and it turns out that
when you do addchild() it calls updateDisplayList again. This is why
my program wasn't working, I had an infinite loop when I called addchild.
I fixed it by adding an if function with a flag.
if (_newBackground){
...
}
Since my updatedisplaylist was being called twice, once with 0
unscaledWidth and once with an unscaledWidth, I had to add another
condition.
if (_newBackground && unscaledWidth != 0) {
...
}
Now I can't seem to get the component to scale with the rest of the
app when the browser window opens. I'm going to start a new thread
for that question.
