[flexcoders] Re: Scaling Custom Components
If you just want to remove all the children, do something like this:
while (this.numChildren() 0)
this.removeChildAt(0);

Hey Alex,
if 0 == childA
can you insert childB at 99 for example.
if so if you remove childA does childB's index change?
can you ensure that you're child will remain at an index?

Look at the code for removeAllChildren.
It will either removeChildAt(0) j times or iterate backwards.

Subject: [flexcoders] Scaling Custom Components
I have a custom component that adds multiple shapes during
UpdateDisplayList. When I scale the browser it calls update
display
list and draws over all of my shapes.
I have tried:
j = this.numChildren;
for (i=0; ij; i++){
this.removeChildAt(i);
}
Before I write redraw my shapes in UpdateDisplayList. I always
get an
outofbounds error after i exceed numAutomationChildren(?). If i
try
the same loop with numAutomationChildren nothing disappears.
It won't let me call this.removeAllChildren (i think because I'm
extending an UIComponent and not a Container)! Isnt there a way
for
me to get all those shapes outta there?
Maybe I'm taking the wrong approach.
Thanks in advance,
Nate
[flexcoders] Re: Scaling Custom Components
Thanks everyone for your response. Now that I understand how children
are added/removed i can take out some of my work arounds in other
projects!
The scaling works great now.
New question:
Is this the best way to scale? Is it expensive to remove and re-add
all the components when I want to redraw? In this component I have
graphics and text and it seems really fast. But what if I used more
complex things like sprites or containers? Would removing all of them
then re-adding them be the best way to redraw?
Thanks guys.

[flexcoders] Re: Scaling Custom Components
The browser window is resizing. How would I just set the scaleX,
scaleY in that situation? By setting those would i redraw for me?

RE: [flexcoders] Re: Scaling Custom Components
I think I need more context. If I had a component with a circle and
triangle and the browser window resized, if I set the component's
widht/height to use %, updateDisplayList will be called with different
numbers and I would just set scaleX/scaleY on either the entire
component or the circle and triangle.
Also look at stage.scaleMode. We use noScale by default.
