[flexcoders] Preventing default onClick-behaviour in List-Component
Hi all,
I want to cancel a list component to change the selection under some
circumstances.
Neither works:
list.addEventListener( ListEvent.ITEM_CLICK, handleChange );
list.addEventListener( ListEvent.CHANGE, handleChange );
private function handleChange (e:ListEvent):void
{
e.preventDefault();
return;
}
To workaround I tried to manually set selectedIndex to the selected value
prior user-click, but I´m also unable to retrieve the previous value.
I read a post by Alex Harui, where he suggested to use the change-event in
capture phase, but that doesnt ever get fired.
Thanks for directions!

[flexcoders] Re: PopupMenuButton: Want to stop the click event and only have the itemClick ev
This post´s a little long ago, but I thought I´d post an answer
anyway:
one can achieve the desired behaviour easily by creating a custom
component that extends PopUpMenuButton.
In your custom component just override the clickHandler-method like
this:
override protected function clickHandler(event:MouseEvent):void
{
//super.clickHandler(event); -- do NOT envoke PopUpMenuButton´s
.clickHandler()
}
In mxml U can then define your own handler only for the button controls
(eg. open the menu only, dont call itemClick-Handler automatically):
controls:myPopUpMenuButton
click = { event.target.open() }
itemClick = { myItemClickHandler(event) } /

Hello Everybody,
I am working with a PopupMnuButton. The PopupMenuButton is skined so
the selected value is not visible. The menu has four items which
when clicked performs respective operations. But when the main
button of the PopupMenuButton is clicked it performs the operation
for the first menu item. I wish to stop that from happening.
Going through the help files I found that PopupMenuButton dispatches
a click event when the main button part of the PopupMenuButton is
clicked, which further dispatches the itemClick event for the last
selected index.
Is there a way around to stop the click event from firing when the
main button is clicked?
I dont want any action to take place if the button is clicked. The
user has to select an item from the menu.
Please advise.
Regards,
Paromita

Hi Owen, I´m also about to use Cairngorm with FMS / SharedObjects - did U find useful resources on the issue in the end? Have U been succesful with your approach? Thx for any hint! Carsten --- In flexcoders@yahoogroups.com, Owen van Dijk [EMAIL PROTECTED] wrote: Hi all, I'm implementing a project now using Cairngorm's framework and uses FMS to provide multi-user capabilities through SharedObjects. It uses the SharedObject onResult handlers to update the model ( concurrent users, number of users connected etc ). Where in the architecture would this functionality fit best? I'd assume i would create a NetConnection 'service' and create a Delegate for the SharedObject and handle the Result and Fault handlers in a Command but this feels a bit weird because the SharedObject is 'persistent', not in the context of persistent SharedObjects but persistent that they are never deleted. I'd believe that Commands can be created and execution ends when the execute method returns ( or it's onResult/onFault handlers ). What do you think, should i implemented as suggested above or is there something i'm missing? -- Owen van Dijk
[flexcoders] Re: AMFPHP / databinding nested arrays
Hi Patrick,
thx a bunch already for answering!!
Actually my example will already allow me to access the values like:
trace( myResultObject[0].day );// prints 'Mon'
trace( myResultObject[0].[0].start ); // prints '100'
...
But I guess there´s no way to use e.g. that 'start' value directly
via MXML binding, hm?
I should rather be using a custom renderer for it or flatten the aray
on the client pre-binding?!
The latter(flatten array on client) just 'feels' a little uncomfortable,
as well as it feels not too good to change the data structure in the
backend 'only' for flex.
thx again regards
carsten

The way you constructed your array might come out like this, but not

myResultObject[0].day.mon.start.100.end.300
Nested Arrays return into Flex as objects. I haven't tried
nesting
an array as complicated as this, I guess it's doable but it
might be better to reorganize your array structure . I think it will
be easier to read than a big old nested array constructor than in php
if you use the following example, and this is how I do it.
?
$my_array = array();
$my_array[0]['days'] =$some array
$my_array[0]['starts'] =$some_other_array
Return $my_array;
?
//in flex your result arrays work like this...
Var someArray:Array = myResultObject[0].days
Var someOtherArray:Array = myResultObject[0].starts
Then you can get your values and organize your arrays which ever way
you like.
Hope this Helps

Subject: [flexcoders] AMFPHP / databinding nested arrays
Hi there,
I guess this is a typical newbie question, maybe someone could
kindly direct me to a tutorial or sample:
I try to bind e.g. using a charts control to a nested array I receive
from an AMFPHP service.
On the php side I have as an example:
$outputArr[] = array('day' = 'Mon', array('start' = '100', 'end' =
'300'));
$outputArr[] = array('day' = 'Tue', array('start' = '250', 'end' =
'600'));
$outputArr[] = array('day' = 'Wed', array('start' = '500', 'end' =
'600'));
return $outputArr;
..which will deliver the data correctly as I can see from the flex
debugger.
In flex I have eg.:
mx:series
mx:ColumnSeries xField=day yField=??? /
/mx:series
Now, how do I access e.g. the value 'start' to use it for
databinding? Well, 'day.start' does not do the trick : )
I had similar probs using XML for binding, where I wouldnt be able to
access sub-children?
Do I have to somehow wrap the server response into an actionscript
object which I'd have to manually add properties to?
Any hint greatly appreciated!!

[flexcoders] Re: beta3 -- Binding XML data to List Controls -- data binding experts?
Hi Tim, Jim,
any news on the issue yet?
I´m a flash developer just starting with Flex and also wonder what
the best way to message/bind/modify ie. XML data to controls is.
In addition to Tim´s question, I also would like to process some
values on the client.
Example: I have user data in an xml-file. I then take ie. name email
values directly from the file to populate a grid while I would like to
process 'last login' values in Flex so I can use date-sorting, etc...
How do I declare the data type for each received value in a list
control?
I would love to hear any hint to start my flex work the right way.
Thx in advance!

Hi all,
I have XML data that is being returned from a remoting service. I
would like to bind this data directly to various List-based controls
(As I understand it, List controls like Arrays/ArrayCollections).
What is the best way to massage the incoming XML data so that it can
be binded directly to List controls.
Any insight is greatly Appreciated.
