Subject: [flexcoders] Flex Modules and external sources


Hi,

a little question for you..

i've a module that could load some images from an external directory.

The structure i use is:

projectname
---some sources classes
---imagedir
firstimage.jpg
secondimage.jpg
---modules
mymodule

So i create an mx:image tag into the module and i set the source property equal 
to the image file path (for example firstimage.jpg)..
this solution doesn't work..why?

any solutions?
thanks in advance

[flexcoders] Dynamic Flex Stacked Column Chart

2009-04-06 Thread jeffreyr6915

I'd like to create a dynamic Flex Stacked Column Chart at runtime, based on 
values out of a database. The following are the steps that I currently follow 
(without success):

1. Query the database and populate chartIemArrayColl with ChartItem objects
2. Iterate through chartIemArrayColl and only create a a new columnseries 
object if there does not already exist on for that 'selection'. Add this 
columnseries  to the columnset
3. Apply this to the chart

Note: I used secondSeries instead of series because of a known defect in Flex 
that makes the charts off center if series is used.

Problems:

1. The chartIemArrayColl contains items that contain the same 'name' but 
different 'value' and different 'selection'. However, in this case that 
particular 'name' is printed on the x-axis multiple times (not correct)
2. The 'selection' should be the legend, but when it is graphed it does not 
seem as though it is connected to the items actually charted

What I'd like to achieve:

1. Column chart with a legend that contains only values of the 'selection'
2. Stacked Column chart that contains values where I can chart the following 
example:

item1 (name=myName, selection=sel1, value=4)
item2 (name=myName, selection=sel2, value=6)
item3 (name=name3, selection=sel1, value=8)

I expect a chart that has myName and name3 across the x-axis (myName should 
only appear once). A column should appear at myName that has one 
color/selection (value 4) stacked on top of another (value 6). A column should 
be at name3 with the same color/selection as item1 (value 8).

Can you please help me with this? Thanks so much in advance

[flexcoders] CairngormEvent dispatch question

What is the difference between:

myEvent.dispatch();

where myEvent extends the CairngormEvent class?

I've been using the 1st code to dispatch my events but, saw in a post the 2nd.

Hello everybody,

I'm playing around with the new sound capabilities of Flash10 and wanted 
to try out an example I found on the internet.
Basically, I ported the DynamicSoundSample1 from 
http://www.adobe.com/devnet/flash/articles/dynamic_sound_generation/ to 
Flex 3.

But I keep getting the error Flex error: type was not found or was not 
a compile-time constant: SampleDataEvent.

Indeed, Flex Builder also doesn't show SampleDataEvent in the code 
completition of import flash.events..

According to the LiveDocs, SampleDataEvents should be available in
Flex 3.3 (and I recently updated the SDK to 3.3 and updated the project 
options):
http://livedocs.adobe.com/flex/3/langref/flash/events/SampleDataEvent.html

What am I doing wrong?

Simplest reproducable code:
---
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute
mx:Script
![CDATA[
import flash.events.SampleDataEvent;

[flexcoders] DataGrid Column Sort Prevents Drag From Updating DataProvider

2009-04-06 Thread chris.cobb40

Hi

I think I've seen this commented on before on flexcoders so sorry for the 
duplication.

In the reply the person who asked the question was told to turn off the Column 
Sort and that would do it but won't this reset the sort order back to default 
before allowing the drag ?

I want to cater for the situation where the user might want to sort the 
DataGrid into reverse alphabetical order and then just drag the resulting first 
row to be the second one.

Maybe I'm using the wrong method of turning off the column sort - I set the 
sort property of the ListColection DataProvider for the DataGrid to null and 
then refresh ?

Any sugegstions please ?

Thanks

Re: [flexcoders] Re: BlazeDS or JSON

2009-04-06 Thread Ivan Bojer

We are using remoting with Blaze. Now, keep in mind that if you do go
JSON route you'll be able to use different UIs (like build small
factor device UI in JS). With remoting you are 'locked in the
solution' (but we like it :) ).

On Sat, Apr 4, 2009 at 3:41 PM, max.nachlinger max.nachlin...@gmail.com wrote:
 I'd personally go with Remoting via BlazeDS.

 With remoting you can:

 1. Map your AS DTOs to Java DTOs, meaning when data arrives from the 
 middle-tier, you get it automatically typed as your AS classes.  (e.g. a 
 remote call to searchUsers() will return an Array of your native User 
 objects).
 2. You can send an AS DTO at the middle tier and it will arrive as its Java 
 DTO counterpart.
 3. Remoting talks via AMF, which, being a binary format, is far less bloated 
 than JSON.
 4. You are not tied to DTOs, you can still send standard objects and 
 primitives across the wire.

 The down-side to the DTO approach outlined above is that you have to maintain 
 2 sets of these objects.  Code generation helps here and its arguably a small 
 price to pay for what remoting brings to the table.

 JSON is a pain as you'll have to do a fair amount of de-serializing and 
 casting, but it you want to go that dark-route, as3corelib has great JSON 
 support.

 I'm still waiting for someone to (fully) implement Google's badass Protocol 
 Buffers (http://code.google.com/apis/protocolbuffers/), which would be a 
 great binary alternative to remoting.

 Hope this rambling answer helps.

[flexcoders] Re: Sharing objects (BitmapData) between 2 loaded swfs

2009-04-06 Thread p0lish_sausage

Hi Tracy,

I noticed LocalConnection through the documentation. Although people have 
mentioned that it shares the connection even across multiple pages in the same 
browser, you would end up getting collisions, which is silly. Have you had 
experience working around that problem?

When you have a very large project consisting of many complex elements and 
states, and A LOT of resources, it makes sense to have one swf that has 
ownership of all resources loaded. Then each satellite swf can reference the 
resource repository and thus minimize loading times considerably.

 I'm wondering if Flex has the capability of having 2 loaded swfs on a

 load a bitmapdata in A.swf, and then reference  use it both in A.swf and
 B.swf at the same time. I'd like when the bitmap in A.swf gets updated the
 B.swf is updated automatically, because it's pointing to the same object.
 
 I've found documentation for SharedObjects, however the amount of data I'll

 shouldn't be hitting the users local disk, so that won't work.
 
 Any suggestions for the above mentioned would be much appreciated.

 Declare a class instance, or make the function static.

 It's customary to name classes with a capital letter at the start, 
 instances
 with a lower case.

 private function callClassFunction():void
 {
 var test:Layout = new Layout();
 test.traceTest();
 }

[flexcoders] Problems opening window from AIR system tray app

2009-04-06 Thread michob

Hi folks,

I'm working on an AIR app that lives in the system tray / dock.  It
should not have a visible window at startup, only a system tray icon. 
After some event, I would like to create one of two windows (depending
on the event).  I've got the system tray part working, but can't get the
window to open...

TrayApp.as:


class TrayApp extends Sprite
{
  //  etc 

  function processEvent()
  {
var wnd:Window = new MyWindow();
mywindow.open();
  }
  //  etc 
}



MyWindow.mxml:


mx:Window xmlns:mx=http://www.adobe.com/2006/mxml;  width=400
height=300
   mx:Label text=hello, world/
/mx:Window



When I run this, I get an exception deep in UIComponent:

TypeError: Error #1009: Cannot access a property or method of a null
object reference.
 at
mx.core::UIComponent/http://www.adobe.com/2006/flex/mx/internal::updateC\
allbacks()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\\
UIComponent.as:5124]


I suspect that maybe I can't call the open() of Window from my app that
extends Sprite because some of the application framework is missing
(like layout managers, etc..).  Maybe it has to extend
Application/NativeApplication instead?  I tried that, but got another
odd exception.

Anyone know how to do this?

Thanks,
Mitch.

[flexcoders] Re: How can I call a function from a class?


There's a couple of ways.  If your class and function are static, like a
utility class that doesn't persist any data, just call
Layout.traceTest();  Note: Classes should be capitalized, in order to
differentiate them from variables.  Another way is to instantiate the
class as a variable:

private function callClassFunction():void
{
  var layout:Layout = new Layout();
  layout.traceTest();
}

[flexcoders] Debugger can't find source for Slider class

2009-04-06 Thread Aaron Hardy

Hey flexers,

In my project I'm using a VSlider in one of my components.  In my
component's actionscript, I set the VSlider's value.  I wanted to track that
value going through the VSlider class but FlexBuilder's debugger can't seem
to find the source for Slider (the base class for VSlider).  I can open the
Slider class in Flex builder just fine and set a break point in the value
setter, but it never stops there in the debugger.  Instead, it ends up
stopping at what I assume is the next line of code it can find source for,
which is the FlexEvent constructor.  In the thread stack, it shows:

mx.event::FlexEvent
mx.controls.sliderClasses::Slider/set value [no source]
...my component stuff.

I tried editing the source lookup path.  Currently it's looking for source
inside: C:\Program Files\Adobe\Flex Builder
3\sdks\3.2.0\frameworks\projects\framework\src.  This should be right and
when I attempt to be more specific by adding another source lookup path like
C:\Program Files\Adobe\Flex Builder
3\sdks\3.2.0\frameworks\projects\framework\src\mx\controls it doesn't seem
to make any difference.

I haven't seen any problems with the debugger finding source for other
framework classes.  I am pulling in SWCs into my project that may have been
built with other sdks.  I doubt any of them use the Slider class themselves
but I wouldn't rule it out.

Anyone have any ideas?  Thanks a lot!

Aaron

[flexcoders] Bar Chart Label - probably easy for most to resolve!!

2009-04-06 Thread flexnewbie06

Hi all, 
I am wondering if it is possible to use a different field for the label than 
the one used in the axis category in a bar chart.  

To expand...

mx:verticalAxis
mx:CategoryAxis categoryField=displayName
/mx:verticalAxis 

mx:series
 mx:BarSeries yField=ip xField=errorIndex displayName=Error Index 
styleName={barColor()}/
/mx:series

I am trying to show a bar chart that shows a list of services delivered by 
their respect delivery %.  I want the label field on the vertical axis to show 
the display name of the service but I want the bar series to be based on the 
IP of the service.  If I try to use the display name of the service it 
backfires because sometimes there are duplicate services with the same name, 
then the bar chart just wigs out and draws those bars on top of each other. But 
there are never duplicate IP's so I'd be safe there.  I just need clean labels.

Obviously the above code doesn't work but that is where my brain is right now.  
Could anyone point me in the right direction.

Re: [flexcoders] Re: Flex Component Kit still needed for CS4?

Nate,

Exactly. This is my question. The adobe website seems to
be inadvertently linking a CS4 website to a CS3 page because they never
specifically state Yes, we are sending you from a CS4 page to a CS3 page,
but you are still required to install this on CS4 as well if you want to use
this particular package as it does not ship as part of CS4.

What do you mean by needed? The component kit is kind of a convenience
for wrapping a flash MC or Sprite so it looks just like a component to Flex,

[flexcoders] ListCollectionView w/ a filterFunction as a dataProvider - Flex 2

Hi all, I've been having weird problems involving Lists, dataProviders, 
ListCollectionViews with  and ArrayCollections.  I was able to reproduce one of 
my problems below.

I have a ListCollectionView (filtered_stuff) that's viewing an ArrayCollection 
(stuff).  stuff initially just has one element.  filtered_stuff has a 
filterFunction that filters out this element.

Here's the weird part.  Clicking on Add item once does not show the added item 
in the List.  Clicking on Add item again will result in TWO items showing up in 
the list.  After that, clicking Add item behaves as you might expect.

Why is it behaving this way?

RE: [flexcoders] DataGrid Column Sort Prevents Drag From Updating DataProvider

A collection is either sorted or not, and if there is a sort, it won't let you

Hi

I think I've seen this commented on before on flexcoders so sorry for the 
duplication.

In the reply the person who asked the question was told to turn off the Column 
Sort and that would do it but won't this reset the sort order back to default 
before allowing the drag ?

I want to cater for the situation where the user might want to sort the 
DataGrid into reverse alphabetical order and then just drag the resulting first 
row to be the second one.

Maybe I'm using the wrong method of turning off the column sort - I set the 
sort property of the ListColection DataProvider for the DataGrid to null and 
then refresh ?

Any sugegstions please ?

Thanks

I am trying to show a bar chart that shows a list of services delivered
by their respect delivery %. I want the label field on the vertical axis
to show the display name of the service but I want the bar series to
be based on the IP of the service. If I try to use the display name of
the service it backfires because sometimes there are duplicate services
with the same name, then the bar chart just wigs out and draws those
bars on top of each other. But there are never duplicate IP's so I'd be
safe there. I just need clean labels.

Obviously the above code doesn't work but that is where my brain is
right now. Could anyone point me in the right direction.

[flexcoders] Re: maven compile flex project

2009-04-06 Thread vvandens

Hi Jonas,
It's always good to talk about design ;-)

So let me clarify (hopefuly) my thoughts. When we talk about MVC, I think that 
there are actually 2 different patterns.

Look at Swing or Flex for instance. They both implement the MVC pattern (maybe 
more MV with a tiny c), right? Their architecture is strongly related to the 
Observer/Observed pattern where the model (Swing model / flex dataprovider) 
notifies its listeners (the gui components) about its changes. Then, the view 
just adapt itself based on the notification it recieves (e.g. an element added 
in a collection). This allows to build rich domain models where the OO 
principles (mainly encapsulation here) are strongly enforced. Your business 
objects live on their own, have their business rules and preserve their 
integrity.
For instance, a table cell editing will set the underlying property of the 
object that may in turn update some other part of the model under its 
responsibility, that will in turn notify some different part of the GUI and 
everything is in sync without anyone having to know the dependency graph. So 
far so good.

But all this is fine and easily implemented in a single memory space (the java 
VM or the Flash one).

Now comes the the client/server distribution. One /old but still useful/ kind 
of approach is to have a pixel-based distribution (X, VNC, Citrix metaframe). 
The application actually runs on the server (with all the GUI stuff minus some 
optimizations) and notifications occur based on painting changes. Sync is 
perfect (actually synchronized) but it is server-resources and bandwith 
killing (minus some optimizations). Encapsulation is respected.

Now comes the /2nd/ MVC pattern introduced with webapps (mainly Struts in the 
Java world ?), where the model is not responsible of notifying the view anymore 
and everything is based on the following scheme : request - controller - 
service (action) - model - and... something has to know exactly *what* has 
been modified on the model and *what* part of the view has to change based on 
these modifications. This somehow breaks the OO encapsulation and the nice 
Observer/Observed pattern. It then leads to thin, not to say anorexic, domain 
models where your domain objects become more or less value objects (because you 
don't want them to update something that you won't transparently be notified 
of) and all the intelligence is on the controller part (service included). But 
the good news is that such an architecture is scalable without over-killing 
infrastructure.

With rich clients (i.e. Flex and Swing) comes the extra burden of transfering 
the state back and forth (the value objects). It may be fine with a simple 
(thin, anorexic) model since you can generate your VOs based on your /real/ 
business objects that actually live on the server. But now, your client *has to 
know what* to send to the server on the next round-trip and *when*. Moreover, 
notifications of problems (or updates) issued from server-side computations are 
delayed until the service request comes back. This is much how the Web (and the 
classic webapps) actually work, no ? The request-response scheme on a service 
basis.

The idea I would like to submit is the following : Is there a design in between 
that :
1/ allows me to keep a rich, encapsulated, service aware, domain model; so that 
I can reuse it across different frontends (even faceless ones), different 
applications and all that without re-coding rules that are business domain 
scoped.
2/ is scalable (at least no actual GUI code running on the server)
3/ garantees synchronization with the view whithout having to break 
encapsulation and let me develop as if I were in a single VM (the Swing or Flex 
MVC). In that case, the client-server distribution (and GUI deployment) remains 
an implementation detail instead of being a first citizen of the architecture.

In other words, I'm looking for a seamlessly distributed Observer/Observed 
pattern.

At least in Java, there are a bunch of library projects that implements this 
kind of server-centric, event-driven, GUI development - Canoo ULC , WingS 
(Ajax), Eclipse RAP. They are great but they still consume quite some memory on 
the server since they mimic the complete UI library with faceless objects (that 
have a size, colors, event listeners, ...).

What I've done in Jspresso is keeping a minimalistic UI state on the server 
that is able to comunicate seamlessly with a flex generic UI engine. All they 
exchange are technology agnostic commands (generic framework-scoped events).

The caveats :
- minimize the network round-trips
- keep a request-response scheme (avoid server push of notifications) but on an 
event basis.
Both are avoided by buffering the server-generated events and send them back 
with the response. On the server-side, all you need is a single BlazeDS 
RemoteObject endpoint that is your event dispatcher.

Sorry for the (very) long answer.

Any thoughts, remarks ? Did I loose my

[flexcoders] Re: ListCollectionView w/ a filterFunction as a dataProvider - Flex 2

That's a good suggestion.  Unfortunately I can't directly keep track of the 
ListCollectionViews unlike in the example.  I have a function that returns 
these views with different filtering functions.  I might be able to listen for 
COLLECTION_CHANGED on the ArrayCollection and call refresh then.

Unfortunately I have another problem, but I'm unable to distill it into a small 
example, which is that when the list has one item in it, and another is added, 
it appears that a duplicate of the first item was made.  I am going to put off 
what I'm working on for now and see if we can switch to Flex 3 later.

Thanks for your help.

[flexcoders] Re: How can I call a function from a class?


Ok, if your class is a component, and has been added to the display list
(as a child of the main class), you can reference a public variable in
the parent class with either outerDocument.myVariable or
parentDocument.myVariable.  Personally, I don't like this kind of
dependency, and recommend creating a getter/setter variable in the class
and set it after the class is instantiated and, if needed, when the main
variable is changed.   A getter/setter is recommended for the top level
variable as well.  This way your class can initialize it's own state, if
desired have it's state changed by the parent, and become re-usable;
without depending on the parent.

2009-04-06 Thread Paul Andrews

LOL.

How about the other way around, how can I access a variable in my main mxml 
from my class package?

Well, the real answer is you shouldn't do it. You really don't want to build 
dependencies between your classes (unless there's a really good reason) or 
between a class and your application.

A really bad way to do what you're asking:

?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute 
creationComplete=doIt()
mx:Script
![CDATA[
var s:String=ABC;
function doIt():void {
Application.application.s+=..DEF;
txtFld.text=s;
}
]]
/mx:Script
mx:Text id=txtFld text=UNSET /
/mx:Application

The Application class has a static attribute application that refers to the 
application scope. Please don't use it without a really good reason.

Really speaking most people issue events inter-class communication (without 
building inter-dependencies), or would pass the variable as a parameter. If 
the variable being passed is an object reference, you can still update the 
value when it's passed as a parameter.

Other techniques people use - static class variables - accessible without 
instance declaration. I think there's something else I've forgotten. It's 
late!

 There's a couple of ways. If your class and function are static, like
 a
 utility class that doesn't persist any data, just call
 Layout.traceTest( ); Note: Classes should be capitalized, in order to
 differentiate them from variables. Another way is to instantiate the
 class as a variable:

 private function callClassFunction( ):void
 {
 var layout:Layout = new Layout();
 layout.traceTest( );
 }

[flexcoders] Pros and Cons of Writing Air UI's in Pure Flash

2009-04-06 Thread Scott Delap

I have a question for the list.  We are currently doing rapid UI  
changes to our Air application.  Our UI designers that have experience  
with Flash have not been happy with the iteration turn around time of  
skinning our UI's.  Complains range from issues with compilation  
time to being able to easily preview changes.  They have proposed that  
we develop our UI's in pure Flash with only Flash level UI controls.   
We'd then embed these UI's as swfs in our Flex/Actionscript code.  I  
can see doing this for some UI components.  However, I must admit I'm  
very hesitant to implement the entire UI this way since it becomes one  
big passive view black box.  Would anyone else have pro's or con's to  
such an approach?

Re: [flexcoders] Pros and Cons of Writing Air UI's in Pure Flash

2009-04-06 Thread Josh McDonald

Personally, I'd think long and hard before doing something like this. It
really depends on how much of the actual work is in the very top layer of
frosting, how much work is done in the meat of the AIR app, and what kind
of feedback you need to have going between these layers.

Perhaps you can get the designers to build simpler components (buttons,
window decorations, etc) in Flash using the FCK, and lay them out with MXML
and Builder. If they're building SWCs with the FCK at least they can expose
[Event] metadata and such, which will make life easier for whoever needs to
tie things together in Builder for the AIR side of things. I'd be very loath
to make SWFs part of my app for anything more complex than image resources.
If it generates Events and exposes an API, I need to interact with it
without regard for its internal timeline, the possibility of memory leaks
caused by loading SWFs (mainly in Player 9), etc.

I agree with them 100% that compile-time is horrible for Builder. Adobe
knows this, and they're working on it. Building from Ant using MXMLC rather
than Builder is apparently faster as-is, and I believe you can get a
signifigant speedup using the compiler from Flex 4 but building against Flex
3 libraries. This opens you up to issues as Fx4 is still in early
development, but most of the changes these days appear to be happening in
Spark and the new MXML stuff, so building against the old namespace using
the Halo components could be a helper. Also, recently on the FlexShow
podcast they interviewed a guy (sorry, name escapes me) who's been
backporting some of the speedups from Fx4 into Flex 3. They're not part of
the official download, but I believe you can patch the compiler source,
recompile with Java, and reap the benefits of his hard work without the
technical risk inherent in building using the WIP Gumbo toolchain.

Enough ranting and suggestions from me, I think - time to yield the floor!

RE: [flexcoders] select non-top level items in a hierarchical menu

2009-04-06 Thread Tracy Spratt

The Menu will dispatch a plain click event for the parent nodes.  Since
menu options also dispatch click, you need to check for tht in the
handler.

So it looks like I can fake this by tracking a stack of open menus and
dynamically adding / removing MOUSE_DOWN listeners to the last menu
opened / closed. This seems... ahem... less than ideal. Anyone have a
better suggestion?

Subject: [flexcoders] select non-top level items in a hierarchical menu
Date: Mon, 06 Apr 2009 13:07:37 -0700

I need the ability to select non-leaf items in a hierarchical menu--is
this doable? Basically, suppose I have a dataProvider like this:

[ { label: 'a' },
{ label: 'b', children: [ { label: '1' }, { label: '2' } ] } ]

I want to be able to select a, b, 1, or 2. I can do exactly what I want
with a Tree, but I was hoping for something more compact. It seems that
selecting a node that has children does not dispatch an ITEM_CLICK
event: it just automatically opens the submenu. I'd like to open/close
the submenu on rollOver/rollOut, and dispatch a normal ITEM_CLICK for
that item on a click.
