Re: [flexcoders] Image component not resizing correctly
You have to set 'maintainAspectRatio' to false if you want the content to fill the image.

RE: [flexcoders] Add check mark to context menu item when running in Web (not AIR)
Thanks Alex. Is it possible to pop up a Flex Menu on right click (without adding JS code and preventing event defaults etc)? Even if I can't check the context menu item, any way of highlighting it (making the text bold or using an icon) would be great with me. All I need is some way to indicate that this is the currently selected item to the user. Is this possible?

Re: [flexcoders] Re: Switching Item Renderers
it does.
Another approach which i have taken (and I find neater, faster and more
memory efficient with less emphasis on binding) is the concept of one 1
itemrenderer and several layouts which you can swop out depending on the
model. This allows you to control shared resources (meaning i create the
least number of fields i have to across several different itemrenderers) and
get extremely intelligent about a lot more with less overhead.
but hey, its personal flavour, spice of life stuff, ya know.

Also a comment on ListItemRenderer, theres an awful lot of methods
that
need
to be implemented to make this work. I doubt all of them are used
in a
List
Senario. Even implementing them all theres still a dependency on
DisplayObject (who's methods seem to be implemented). It does feel
to me
like the architecture seems a bit off. I mean if all of those
methods are
implemented why is there still a dependency on DisplayObject.
Its not just enough to implement IListRenderer which seems to
defeat the
purpose of an interace

Hi
I was wondering if anyone had any luck with the following senario
in
flex.
I'd like to be able to have a custom item renderer which
delegates to
another renderer inside.
The reason for this would be in a datagrid for instance
displaying a
checkbox if the dataprovider for the row had a boolean value.
Using the
default item renderer when the value was a non boolean.
Basically I was hoping to use a proxy object (though not
necessarily
the
proxy class) so that I could a renderer which delegated all of
its
responsibilties to a sub renderer.
Hard to explain.

I think the following gives a clearer idea of what I had in mind.
This
is
only knocked up quickly for the purpose of showing the idea.

{
this.checkboxRenderer = new CheckBox();
this.defaultRenderer = new DataGridItemRenderer();
this.currentRenderer = defaultRenderer();

//If the data for this cell is a boolean

Re: [flexcoders] Re: FABridge Problem - Please help!
Alex, I thank you for your patience. However, in one of my earlier posts on this thread I did give quite a lot of details about my particular situation (which is almost certainly different, but at the same time, related to, the other posters issue). In my case, I'm using an IFrame component (from http://code.google.com/p/flex-iframe/) to display a credit card data collection processing application (for PCI reasons, we do not wish to have the CC data collected via our main application) What I wish to happen, is for the 'hosted' app to be able to tell the 'hosting' flex app that it has completed its job, so that the flex app can change the ui, to present the main dashboard again, or perhaps a new order builder screen, or whatever. The problem is that my hosted html app (via javascript) is unable to communicate with its host flex app. There is an example of exactly this sort of behavior here ( http://ccgi.arutherford.plus.com/website/flex/iframe/IFrameBridgeTest/ ). FYI, I know for sure that this doesn't work (on Windows) with Chrome of Safari, but it does work with IE, FF, and Opera. What I've done, is to take the flex3 project here( http://code.google.com/p/flex-iframe/source/browse/trunk/examples/IFrameCommTest/ ), and just do a simple conversion of the code to flex4. I've exported my version of the project to facilitate help ( http://www.mediafire.com/file/172448jkkgva4ki/iframeCommTest.fxp ) The issue I'm trying to resolve, is why the code works fine in flex3, but not in flex4, and my best guess as to what is wrong is that its got something to do with swfobject being used in the flex4 version causing a change to the location of the FABridge object in the hosted html pages DOM. Hopefully that clears up some of the confusion. Thanks -- Brian J.

Re: [flexcoders] Slow connection to a server
Try using Swiz. There is a delegate helper class that allows you to timeout the async request for a certain amount of time. As long as you are sequencing your events correctly and taking advantage of binding, you shouldn't have to worry about slow connections.

[flexcoders] couple questions about android / air
I have been trying to code an android app in java and decided to take a look at air; I've read some things and need to be clarified about a few items: 1) does the android phone need to have some sort of 'air' installed on it? It seems as if compiling makes a regular .apk but I've also read that there was something necessary on a phone... 2) Flex 4 can or can't create the necessary projects? Awhile back it was necessary to start with a flash project but unsure where that stands now. 3) does an android / air app have all the same framework intents that a java app would? For example, I'm dealing specifically with something that works with Alarm Manager; I'd normally set up an intent that would repond to my Alarmmanager setup, and it would respond when fired; air projects work the same way?

Brian, Thanks for the additional info, but what I am really asking for is unambigious language about what your debugging has discovered so far.

I've got the open nodes working pretty well and the refresh use case also mostly works (I store the selection as guids from the objects in question and find them again after the refresh).
