[flexcoders] Re: Application container failed to capture KeyboardEvent
Thanks Alex. That works!
When I switch to another application and then switch back, my all
flash application loses the focus and no event fires at all unless I
click somewhere in it. Is there any way around it?

No children of the Application have focus, so there are no events to

not the top-level displayobject so your handlers will not pick up events
from popups either.

[flexcoders] LocalConnection Bug?
I tried to send an XML object over LocalConnection, and noticed if this XML doesn't have any child node, the other side will only see an empty one. For example: lc.send(lc_id, fn, new XML(a b='1'/)) lc_id.fn() will see an . However if we send ab/b/a, things work well. Is this a LocalConnection bug? Any workaround? I am using flash9/AS3. I thought about toString() but since I may also send objects containing XML object, it will be hard to decide when to do this conversion to/from string. Any ideas? Thanks! Tim
[flexcoders] Re: TitleWindow missing all focus events??
Thanks, Roman. Actually you answered my another question: I have been
trying to figure out why I cannot focus in the edit control inside the
titlewindow :) Where did you learn those good tips about relatedObject ?!!
I am still a little puzzled by how focusIn works. I realized I have to
do these two lines before the focusIn/OutHandler gets invoked:
this.addEventListener(FocusEvent.FOCUS_IN, focusInHandler);
this.addEventListener(FocusEvent.FOCUS_OUT, focusOutHandler);
Does it mean by default, TitleWindow doesn't get FOCUS events
dispatched to?
Thanks again for your great help!

Overloading focusOutHandler/focusInHandler helps. You'll be able to
handle
FocusEvents there.
Like in
protected override function focusOutHandler(event : FocusEvent) : void {
if (event.relatedObject == null || !contains(event.relatedObject)) {
// event came from outside not from one of the children
}
super.focusOutHandler(event);
}

I tried to capture the TitleWindow focus, which I did, but somehow I
can no longer focus in its RichEdit component. Attached is my code.
Could anyone shred some light on it? Thanks!

I have an image in a canvas container, and when I resize the canvas,
the image resizes as I expect. However, the image position doesn't
change at all, unlike in a Flash applicaiton.
For example, on a 300x300 canvas, I load an image of 100x100 at (100,
100). If I double the size of the canvas to 600x600, the image is
automatically resized to 200x200, BUT still at (100, 100), instead of
(200, 200)!!
What will be the solution for this? Please help!
Thanks in advance!!

[flexcoders] Writing a Custom Data Provider
Hi,
I am trying to write a custome data provider for my list control. My
data is not an array, so I am trying to rewrite all those APIs. Here
are some questions:
1. is modelChanged event subscription handled by the flex framework?
In another word, do I need to do any thing besides calling
dispatchEvent({target:this, type:modelChanged, eventName:...)?
2. Is there any good example I could follow? I tried this example
(http://www.macromedia.com/support/documentation/en/flex/1/mixin/mixin3.html),
but ran into many issues, such as:
a. getParent() required by the compiler. It's not in the ASDoc,
however;
b. I saw many warnings in the log:
Warning: getChildNodes is not a function
Warning: __get__editable is not a function
Warning: hasChildNodes is not a function
Warning: getParent is not a function
...
c. The GUI doesn't update itself unless I hover my mouse around.
Any advice will be greatly appreciated!
Tim

[flexcoders] Re: dynamically creating children suggestions?
That way for each different XML, backend Flex server needs to compile
it into a new swf, which, in my experience, has been a not so fast
process. Robert's screen is going to hang either way.
But frankly, I don't have a solution :(

creating your own UIObjectDescriptors, and staggering the drawing

frame.
Stepping back, why not have a server side process generate the MXML
(since it's just XML to begin with and you are merely changign the
format), have the server-side component (CF/Java) write out the MXML,
and then use a Loader to hit the MXML file?
10 billion more ideas of course, Matt'll put the smack down when
he finishes his tea and crepes.

So my flex app gets this XML chunk, I loop through the XML and based
on certain parameters in the example XML above, and in each loop, I
call createChild on a Form component I have in my MXML file and I
build a form that displays to the user various filters they can set
for the report they just selected.
I'm dynamically generating DateFields, Textfields, Lists, and a
custom Range component that I created whose MXML file looks like this:
