Re: [flexcoders] Dispatch an event from a non visual non IEventDispatcher class
You can use composition to acquire the functionality of EventDispather, in other words add the instance of EventDispatcher class as a property of your VO class More on this: http://www.gskinner.com/blog/archives/2007/07/building_a_stat_1.html http://www.gskinner.com/blog/archives/2007/07/building_a_stat_1.html -- Best regards, JabbyPanda On 11 July 2010 08:13, dorkie dork from dorktown dorkiedorkfromdorkt...@gmail.com wrote: Is there a way to dispatch an event from a class that doesn't extend EventDispatcher? For example, lets say you have 30 different value object classes. You want to have one method called invalidateData() that dispatches an event to get the latest content from the server. Since I want to keep the data separate from the view I may need to call this in several different places. Any help would be appreciated.

Re: [flexcoders] Re: Capturing ENTER key in a Numeric Stepper
Hi Andrew.
Can you trap the ENTER (keyCode = 13) on a Numeric Stepper? I've been
failing to do this... :(
When a user presses the ENTER key, I want to perform an operation, such as a
search... So I'm thinking I need to somehow trap the ENTER key and dispatch
a custom event.
Mmmm... Any ideas?
Cheers,
Nick

Re: [flexcoders] Capturing ENTER key in a Numeric Stepper
Hi dork, how you doing?... Thanks for the info on this...
Have you managed to achieve this when using a NumericStepper for your form
objects? i...@ve just this out as an example:
http://flexmusings.wordpress.com/2008/10/30/using-default-button/
And it works when pressing ENTER in either of the TextInputs but if I pop a
NS control on the form and press ENTER from within that it doesn't invoke
the defaultButton?...
Here's my code: http://pastebin.com/65HwfuGf
Cheers for the help...

On enter, I want to dispatch a submitSearch event but can't seem to detect

Any ideas will be great..

[flexcoders] Re: Capturing ENTER key in a Numeric Stepper
I would probably have an event handler to deal with ALL keystrokes, and within that have a switch statement. One case of the switch statement would be case '13': var searchValue:int = myNumericStepper.value; doTheSearch(searchValue); break; So when the enter key click is captured, the code goes and looks at the number stepper and sends whatever its current value is to the search function. a --- In flexcoders@yahoogroups.com, Nick Middleweek n...@... wrote: Hi Andrew.

[flexcoders] stopping accodion animation
Hey all, I have to be able to dynamically remove children from an accordion container. Problem is, this causes a crash when the animation that runs on the selected child is running when I need to remove the panel. I see no way to force this animation to end or register for notification of it ending. Am I missing something? Turning animation off is not an option. I have worked around this to try to ensure it is impossible for a selected child change to occur anywhere near the remove child, but I would rather code this more defensively if possible. thanks! (ps, I am using 3.5 targeting FP 10.0.0)
Re: [flexcoders] Re: Capturing ENTER key in a Numeric Stepper
Andrew - cheers. My problem was that I am working with a custom Numeric
Stepper, I had extended the base control it so it could support null entries
and to be quite restrictive with the inputs... 0-9, delete key, backspace,
etc... I forgot to include ENTER.. doh! :-)
After your post, I decided to go back to basics and testing and
trace(event.keyCode.toString()) on the keydownHander...
Cheers, it's all sorted. I'm now firing out my own FlexEvent.ENTER from my
custom numberstepper.
nice! :-)

[flexcoders] show points on linechart. display the Legend of each line series [1 Attachment]
Morning all of you.
I need you help about adding the Legend Tag in your solution of showing
points on lineChart mentioned in this
link:http://www.mail-archive.com/flexcoders@yahoogroups.com/msg36175.html
In fact, i do the same thing like you (all work good). but the only
different thing that i would want it's to display the Legend of each line
series.
so when i add the tag mx:Legend dataProvider={myChart}/ which myChart
represent the id of the lineChart,
i have this error: TypeError:Error #1034: Type Coercion failed: cannot
convert mx.charts.chartClasses::legendd...@cc33701 to mx.charts.ChartItem.
i tried to add the import like
import mx.charts.Legend;
import mx.charts.LegendItem;
import mx.charts.chartClasses.LegendData;
