RE: [flexcoders] Why never create an item renderer?

[Alex Harui]

It is good enough if you shipped it and got paid :)

If you want to post the code for a renderer, we can offer opinions on the pros 
and cons of your implementation.  It might be good education for many.  I don't 
have time to judge dozens of renderers so we can just start with one of yours 
and discuss it.  There is usually a trade-off of ease of programming vs 
performance and memory optimization.  The smaller and faster you want it to be, 
the more work you have to do.  If you're only gonna have 7 renderers on screen, 
it doesn't matter as much as if you are creating DataGrid renderers for a 20x20 
grid.

I've created a few. I've recreated a few working ones because I want to

I can't stand by either of these sometimes you need things to just work,

If it works, works fast, and its not memory hungry then it is correct :-)

Re: [flexcoders] Set child properties from event.target

[Fotis Chatzinikos]

You can either set the buttons visible property to a bindable property and
set this to true in the event handler or:

(event target as Panel).getChildAt(xxx).visible = true //xxx is the index of
the button

if you do not know the index of the button you can loop in the Panel
children searching for a known property
for example name='myButton'

[flexcoders] charting and/or grid replacements

[Pan Troglodytes]

Are there any 3rd-party charting and/or grid replacements in progress that
anyone wants to talk about?  I'm looking to move away from the
AdvancedDataGrid and possibly also Flex charting and am wondering what might
be on the horizon.  Right now Adobe pretty much has the only game in town
for these Flex components as far as I know.

I really wish DevExpress could be brought around to developing for Flex.
Their grid components can have a incredibly steep learning curve due to the
staggering amount of features, but I've found them to be quite a perfect fit
with a professional quality application.  I can only imagine what they'd
build from scratch for Flex.

This is not to dump on Adobe, necessarily.  They're trying to organize their
budget where they thing it's most effective, even if I disagree with it.
But without a rich 3rd-party component ecosystem, I'm afraid that this great
technology (I'm totally in love with the general process of programming for
Flex) might wither on the vine.

[flexcoders] DateField - minYear and maxYear - don't work if they contain calculated value?

[flexcoder2008]

I have a DateField and if I set the minYear or the maxYear property to a value 
directly, everything works great.

eg.  



But if I want to use a calculated value in there, it doesn't work.  I can 
navigate past this value. 

eg.

[Bindable]
var year:int = new Date().getFullYear();






Why is this? Does anybody have a workaround for this?

RE: [flexcoders] Why no event dispatched?

[Tracy Spratt]

Oh, I see, you are only testing the failed event.

 

Are you intentionally failing the login when you test it?  Are you sure the
dispatch event code is being run?

 

Also, are you sure the login manager is in the document hierarchy?  Your
component structure is not clear.

[flexcoders] AIR ApplicationUpdaterUI Not Initializing

[michaelisraelcaplan]

Hi,

I'm using the Flex SDK 4.0.0.9916, and cannot get the ApplicationUpdaterUI to 
initialize.

Following creation complete, I initialize the ApplicationUpdaterUI object, and 
call the ApplicationUpdaterUI.initialize() -- code snippet below.  

The object appears to initialized properly according to the data popped out in 
the application log:

(air.update::ApplicationUpdaterUI)#0
  configurationFile = (flash.filesystem::File)#1
  currentVersion = "0.2"
  delay = 1
  isCheckForUpdateVisible = true
  isDownloadProgressVisible = true
  isDownloadUpdateVisible = true
  isFileUpdateVisible = true
  isFirstRun = false
  isInstallUpdateVisible = true
  isNewerVersionFunction = (function)
  isUnexpectedErrorVisible = true
  isUpdateInProgress = true
  localeChain = (Array)#40
  previousApplicationStorageDirectory = (null)
  previousVersion = ""
  updateDescriptor = (null)
  updateURL = "http://www.ddxint.com/service/default/desktop_update/updates.xml";
  wasPendingUpdate = false


However, none of my events are being triggered.  My Apache access log doesn't 
show any hits on the defined URL.  Also, calls to checkNow() do absolutely 
nothing.  The only things that I am seeing is that the user application  local 
store folder is being populated with an "#ApplicationUpdater" folder with a 
state.xml file:

This seems to show that the updater is doing something...  but what?

Re: [flexcoders] custom components destroy Flex design mode ....

I've run into similar situations before with 3rd party components.  For some
reason, some of them just utterly break the MXML design mode.  I've also
done it myself when subclassing the charting components.  You just get a big
rectangle with a big red X over the whole area.

It is not always given as advice.  I give that when I see that a developer

Re: [flexcoders] Flex and REST

[Richard Rodseth]

The other issue is error responses. In the apps I work on we have specific
XML or JSON result formats for application errors, which means the Flex app
must handle those responses differently. If the service is using HTTP header
error responses instead I believe the Flex app can't see them, though I
forget the details.

I assume you've seen this thread:

re: [flexcoders] How to dynamically add series to an areaChart/cartesian chart

[Wally Kolcz]

With actionscript you can add them on the fly with addChild(), I don't think 
you can add them dynamically with mxml unless they are 'static' options that 
may or may not appear, then I think you can just have them set to visible=false 
and includeInLayout=false.

Hi, 

I am working with about 8 charts in my ui, they all share common functionality, 
how do I dynamically add series to my charts... is it as simple as setting 
series on my super.chart?

Are there any examples out there that show this?  Best practices too? Using 
mxml or actionscript?

Thanks,

Re: [flexcoders] What does [Bindable("dataChange")] do?

[Johannes Nel]

its not specific to any class, its part of the framework. its a very handy
way to optimise in truth, when a specific property updates you only fire
that one event, and only the property(ies) associated with that event via
binding will update.

you can also have multiple binding tags with one getter, for example
[Bindable("eventA")]
[Bindable("eventB")]
funciton get a():String
{
}

lastly its a way to make read only properties bindbale.

it means the binding will only update when the dataChange event fires on
that object.

Re: [Spam] [flexcoders] Re: What does [Bindable("dataChange")] do?

[Nick Middleweek]

Hi, thanks for the reply...

I can see similarities in the example to the code I'm looking at but my
setter doesn't dispatch an event - does this mean the
[Bindable("dataChange")]  isn't needed?


Also, is [Bindable("dataChange")] specific to the data property or the
IDataRender Class?... I mean is it a coincidence that the property is called
"data" and the event is called "data"Change?

Or does the IDataRenderer dictate that there must be this
[Bindable("dataChange")] meta tag in order for the data getter and setter to
function correctly.

INterfaces are new to me as well :)


Cheers,
Nick

i'm still new to Flex... I'm going through someone's code and i'm wondering
what *[Bindable("dataChange")]* does.

It's in an ItemRenderer MXML file for an Advanced DG. it's not inside any

Can anyone shed some light on it please?

[flexcoders] line series - resize issue

[Gautam P]

Hi,

I have a linechart within which there are a lot of line series. When I hide
a line series I want the line chart to resize/adjust to the visible line
series only.
This doesn't happen if I make the series I want to hide using visible=false
and includeInLayout=false. However the linechart does resize if I update the
dataprovider. Is there any way to resize the linechart with only visible
lineseries without updating the dataprovider?

Thanks,
Gautam.

Re: [flexcoders] Can we command an ole2 (COM) via AIR

[b_productiv2000]

This is 1% of our application, it's not its only function.
Our application is a customer relationship management dedicated 
to the insurances, and at one moment in the process (when the 
offer or the order is done) we've got to print a document based 
on a template that each client is supposed to create (i insist, 
we didn't know the template before).
The old application is based on the powerfull and well known 
merge function of word, so we are trying to achieve the same 
thing but in our new AIR application.

I hope to be clear enougth and that you understand my 
approximative english.

[flexcoders] Re: how to show icon in ToggleButtonBar

[grg_blls]

Thank you Steve for the example. 
(I also had a look at the links you provided :)

Though all seem very straightforward, somehow it keeps on disregarding showing 
the icons, without any errors. 
Looks like the itemRenderer 'forgets' to place the icons, even if the iconField 
is set at the mx:Menu control and points correctly to "@icon" property of the 
dataProvider :)
The icons are properly embedded of course!

As other matters are more pressing now, I will drop this icon "looks" 
improvement and remain with the labels already there, while keeping on with the 
main project development. When I have time I will look again to this "problem" 
for the shake of it.

Thanks again for your help

[flexcoders] change default rollover behavior of chart data point

[Ivan Wang]

Hi, all
Does anyone got some idea about how to change default rollover behavior of 
chart data point. Say if I use CircleItemRenderer:  For line series, I'd like 
to enlarge the inner circle and change the white fill color. For area series, 
I'd like to remove the default behavior, and to highlight the whole area fill 
background instead. 

The default rollover behavior exists no matter the chart's selection mode 
is "none". But I went through related source code, only find how to change it 
when the selection mode is not none. I'm pretty sure I missed some piece of 
code that control it. Does anyone ever researched this part?

Thanks
Ivan Wang
