[flexcoders] Re: Using arraycollection as text for a flex TextArea Component.

[stephen_anson]

It looks like you are 'joining' objects, into a string.
If you created a product class and provided a suitable toString() method I 
think that would solve the problem

[flexcoders] Re: Best book for learning flex

[stephen_anson]

I think it depends on your development experience.
For a total noob i'd look at essential guide to flex3  - charles E Brown

the flashbuilder / flex bible is also good with a little less hand holding.

and if you like looking at examples the flex cookbook is good.

It's also worth doing the adobe flex video in a week.

Hi,

I have a custom item renderer for a list component that contains a button.
I would like the itemClick event to target clicks of the button not the whole 
renderer

What is the best way to go about this?

any help much appreciated.

[flexcoders] Re: Data grid column sizing is changing when returning from another state

[stephen_anson]

Well I'm not setting the width apart from in the mx:DataGrid attrib. to 991
However if I specify 100% rather than 991 then it works - the columns maintain 
their widths on returning to the prev state!
I can live with 100% but that behaviour seems odd to me.

Hi,
I have a data grid that has several columns, when i go from one state and back

Another variation is to use TextMetrics to figure out the size of the text.

[flexcoders] Flash builder 4 installation options

Hi,
I currently am working on Flex projects using flex builder 3, installed as a 
plugin to eclipse.
I also do java server development using eclipse.
I'm looking to upgrade to take advantage of the new tools in flash builder, but 
am concerned that this may give me issues. 

Anybody got advice in this area, as I've googled and found nothing helpful

I have a client who wants to develop a desktop application, and has the need to 
communicate with a web service via soap.

they have stated that the service will send a cookie and expect a return of 
that cookie with each request.

it sounds like this is not possible with flash?

[flexcoders] Printing on Mac

[stephen_anson]

Hi,
Anyone any idea why printing on Mac might result in an empty page whereas on 
windows its fine?

I'm using all the standard techniques, with Print jobs etc. But I am not adding 
the print sprite to the stage.

I am guessing that there is some difference in the way the flash players 
implement printing.

any pointers in the right direction much appreciated

Hi,

The server side dev team have asked if I can send a HEAD request to their home 
page in order to 'keep my flex app logged in'

URLRequest will not allow the method as  a "HEAD" as far as I can see.

And URLLoader returns the html data, I basically need to send only

Any ideas much appreciated

[flexcoders] issues with printing on mac and linux

[stephen_anson]

HI there,
I'm trying to print out a sprite called 'plan', but its not appearing on Mac 
and Linux. Here I draw my plan sprite into a bitmap, add that bitmap to a 
sprite and try and print that. 
I get blanks on Mac and Linux.

Any ideas really appreciated!

var pj:PrintJob = new PrintJob();
if( pj.start())
{
var planh:Number = plan.height;
var planw:Number = plan.width;
var ph:Number = pj.pageHeight;
var pw:Number = pj.pageWidth;
var bd:BitmapData = new 
BitmapData(planw, planh, false );
var bmp:Bitmap; 

var s:Sprite= new Sprite();


// figure out a scale that will suit 
the print
var rw:Number = planw/pw;
var rh:Number = planh/ph;
bd.draw(plan, null,null,null,null, 
true);
bmp = new Bitmap(bd);
if(rw >1 || rh>1)
{
var scale:Number = rw > rh ? 
1/rw : 1/rh;

bmp.scaleX = scale;
bmp.scaleY = scale;

}
s.addChild(bmp);

pj.addPage(s);
pj.send();

}

[flexcoders] Re: Observer pattern

[stephen_anson]

I notice something that is possibly similar in my app, eventually foun
d out the focus manager had a reference to a ui component in the
popup. You can see if it this by looking at references in the
profiler, by taking a memory snap shot and looking at your object

[flexcoders] When to use Cairngorm front controller ?

[stephen_anson]

Hi, I'm fairly new to cairngorm,

I have an app that produces many events via 'user gestures', so for
example I produce a group of items one of which can be selected for
further editing of its properties via a form.

Should cairngorm I produce custom events and hookup to the front
controller for every single mouse click etc, or is it best to reserve
the cairngorm architecture for specific parts of an application such
as sending and receiving data to the server.

thanks Steve
