Re: [flexcoders] Possible to use labelFunction and change text color?
Better off to use a cellRenderer G. Here's some code to get you started.
?xml version=1.0 encoding=utf-8?

mouseOver=doMouseOver()
mouseOut=doMouseOut()

if(state != selected)
{
lastStyle = this.getStyle(color);
this.setStyle(color, 0x648BCB);
}
this.setStyle(textDecoration, underline);
}
public function d(o)

It's the wee hours of the morning and my brain is fried. Is it possible
to set the text color for the label of an individual node in a tree?
Thanks!

Re: [flexcoders] setPropertiesAt and Cairngorm are not playing together nicely
hi,
looks like a lifecycle problem to me.
try to see if the DataGrid is already created when you try the calls that fail.
note that if the DG is inside a viewstack or another container with a
creationPolicy, it might not get instantiated right away unless you
set the policy to all
best,

Re: [flexcoders] Re: Updating the data back to database
If you need to do it in Flex 1.5 you relally need to put significant amount of code in your base objects. We implemented in 1.5 just what Dave is suggesting with "PowerBuilder" approach ( which was considered astandard of Enterprise RAD - Rapid Application Development)- high-level objects that keep track of the state of each database record, with an ability to send the changes to the server. Unlike Flex 2, we implemented automaticgeneration of "updates" based on original "selects" and minimal metadata so you do not need to write your own persistence layer. Just write SQL to select the data - and Java/Flex UI is generated for you automatically - including Java DAO, updatable datagrids, forms and master/details. And we also placed nice toolkit on the top of it so users can select/apply their own layouts (persisted in database) in run-time if needed. Of course, code generators can be tuned for iBatis or Hibernate or any other - as long as there is justification for it. Other things that I have not seen in Flex 2 but are the must for real-life applications are "transaction" services, when you can submit changes to multiple objects at once. For that we had to write specialized gateway so we would preserve AMF/HTTP infrastructure for development (called RPC in Flex 2) while adding "transactional" methodology to the calls. So, it is very possible - the only bad news is that anyframework as such has learning curve, especially if the team is skilled with Web technologies, and do not have PowerBuilder one. When we bringthis to our customers it takes anywhere between 2 to 4 weeks of mentoring to get the team to RAD mode. While it is definetly more economical then writing all modification code for any application that is more then just few screens, and proved to produce much fewer "errors",decision to use it has to be made very early in the development process (or pilot if possible).

However Flex 2.0 will include the"Enterprise Data Services" which include exactly this functionality. This was demonstrated at MAX last fall and Adobe has presented severalweb casts on it. As you note (and much like other existingclient/server products like PowerBuilder) the data services willinclude the ability to track "changed" or "dirty" data on the client,marshal those changes to the server, and will provide for a pluggablepersistence layer which will handle writing the changes in anoptimized way to the underlying data store.

http://flexapps.macromedia.com/flex15/chartexplorer/explorer.mxml.
Look for Slider selection of time axis under Misc Techniques and
Examples at the bottom of the tree. From there, just add an
HScrollBar component that controls the start and end positions of the
HSlider. Here are some excerpts from my code:
In ActionScript:
function rangeScroll(o: Object) : Void {
slider.values = new Array(o.scrollPosition, o.scrollPosition +
o.pageSize - 1);
sliceResults();
}
and in MXML:
mx:HScrollBar id=timescroll minPos=0 maxPos={scrollbarMaxPos}
width=100% scroll=rangeScroll(event.target); /
You'll probably also want to set the various page size and scroll size
properties of the scrollbar according to your own needs.

Re: [flexcoders] MXML Components and Classes
You can create ActionScript or MXML class; they are effectively the same thing. The only real limitation I've found is I've failed to create extensible containers via MXML; meaning, extending CheckBox, Label, Loader, with MXML works great, but extending Containers like VBox, Panel, etc. gave me problems. I can't remember if it WAS supposed to have 1 child or NOT supposed to have any children... anyway, if you use ActionScript, works like a charm, but I like MXML better. If the mx:Script tag is the first tag after Application, those methods will become class methods, just like others. If you put it after uicomponents, I think it just becomes like an include instead. You can still put it after mx:Style and mx:Metadata tags which is cool.. - Original Message - From: Trey Long [EMAIL PROTECTED] To: flexcoders@yahoogroups.com Sent: Friday, January 20, 2006 12:12 PM Subject: [flexcoders] MXML Components and Classes Quick question about making custom components.

Right now I have an external .AS file that is just some import statements and a collection of functions (no package or class definition). How can I link the .MXML component to a class, or write the components class code?

[flexcoders] Wrapping Images and Bitmaps
Alright, the best way to describe this is with a use case. I have a Canvas on which rests an Image, let's say this image represents a map of the globe. Now, I have some nice panning code that interacts with the edges of the screen to move the x and y value kinda like your standard RTS game (ala Starcraft). Here's the interesting part, I would like to have the very left or very right edge of the map wrap around and begin again, effectively making no end to the horizontal scrolling. Gotchas: There will be a ton of crap painted on top of the map, like dots connecting different points with lines... So, the method has to support keeping those map widgets in tact. What I have thought of: I thought that if I could cache the canvas as a bitmap and access the bitmap data that I could wrap the pixels around bit by bit. Well, if any methods come to mind, please give me your input.

Re: [flexcoders] Performance question - please help!
Answering from the 30,000ft view, my suggestion is to utilize Flex 1.5 Flash 8's bitmap features. Flash Player 7, which is what Flex 1.5 outputs, cannot handle the amount of data points you want with acceptable performance, either in code or displayed. While paging can be effectively employed, you'd probably lose the visual representation you are going for. Therefore, utilizing the bitmap imaging code Flash 8 exposes, you could incoporate a component into Flex that utilizes blitting of those data points to 1 bitmap. The upshot us, it can scale infinitely since it's 1 bitmap, and an acceptable, predicatable RAM usage. The downside is, you still wouldn't really be able to retain the data if it's in the 100,000 range, but if it's just 60 pointers to machines, that's cake. - Original Message - From: Jonathan Hirschi [EMAIL PROTECTED] To: flexcoders@yahoogroups.com Sent: Friday, January 20, 2006 4:10 PM Subject: [flexcoders] Performance question - please help!

Re: [flexcoders] Performance question - please help!
So in terms of Flex 2, would it be able to possibly handle this amount of data effectively since it uses flash 8? It sounds like you are saying that 1.5 has trouble displaying that amount of data because of ram usage problems? does that same problem exist in flex 2? Is there a max on how much memory flash player 7 is able to use effectivly? is that max much larger in flash 8.5 player? It sounds to me like it might be easier to port this thing to flex 2 than it would be to try and plug in to flash 8 bitmap features and draw my own graphs. as far as data points, well, it's 200 machines * 60 properties * 60 minutes = 720,000 data points that i need to hold in memory at any given time. I'm also being asked to update the data points at a rate of once per minute ie 200 machines * 60 properties = 12,000 updated data points per minute with an eventual goal to get those updates down to once every 10 seconds.. is that something that is doable by flex 2 even? They've got an app here written in mfc (c++) that can do it, but they'd like to have it accessible from anywhere on the web... Have there been any performance papers published on flash describing memory usage, etc?

RE: [flexcoders] View Directory Tree
Have your middle tier build an xml representation of the filesystem tree, pass that back to Flex using HTTPService, and assign the result (resultFormat=xml) to a mx:Tree control's dataProvider property. Look at the docs to see what the tree wants by default and craft the xml accordingly. That way you won't have to worry about using labelFunction.

Flash Player 7, which is what Flex 1.5 outputs, cannot handle the amount of data points you want with acceptable performance, either in code or displayed. While paging can be effectively employed, you'd probably lose the visual representation you are going for. Therefore, utilizing the bitmap imaging code Flash 8 exposes, you could incoporate a component into Flex that utilizes blitting of those data points to 1 bitmap. The upshot us, it can scale infinitely since it's 1 bitmap, and an acceptable, predicatable RAM usage. The downside is, you still wouldn't really be able to retain the data if it's in the 100,000 range, but if it's just 60 pointers to machines, that's cake. - Original Message - From: Jonathan Hirschi [EMAIL PROTECTED] To: flexcoders@yahoogroups.com Sent: Friday, January 20, 2006 4:10 PM Subject: [flexcoders] Performance question - please help!

RE: [flexcoders] Performance question - please help!
In AS3, you should declare a non-dynamic class for your data items
rather than using untyped Objects. For example, don't use data items
like
{ foo: 100, bar: 200 }
Instead write
new DataItem(100, 200)
where
class DataItem
{
function DataItem(foo:int, bar:int)
{
this.foo = foo;
this.bar = bar;
}
var foo;
var bar;
}
A non-dynamic class like DataItem takes a lot less memory and you can
access foo and bar faster on it.
A plain Object is basically a name/value dictionary where AS3 has to do
a name lookup in a hash table.
By contrast, a non-dynamic class is laid out compactly in memory so that
AS3 knows that foo is at offset 4 from the beginning of the data item in
memory, bar is at offset 8, etc. It can then read and write them quickly
without any lookup.
When you use a non-dynamic class, each int, uint, Boolean, and object or
string reference will take up 4 bytes, while each Number will take up 8
bytes. Each instace also has a 16-byte header for keeping track of what
class it belongs to, etc. There is also some rounding up because the
memory manager allocates only chunks of certain sizes.

I have to parse through those records to create the Charts. I'm pulling the records back with a remoteobject request. I should also further say that the 760,000 records are all for the initial request. subsequent requests will be a lot less... but still along the lines of 12000 records every minute. records are coming back in the format of: machineID, propertyid, minuteid, propertyvalue 1,1,213,98 1,2,213,78 2,1,213,94 Everything is numbers Thanks for the explanations jester. --- Jonathan Hirschi [EMAIL PROTECTED] wrote: Well, the way I'm planning this out is that at the moment, i need to have 60 chart objects with essentially up around 40 or so series per chart (estimated - could go as high as 60). Each series is an array of numbers. Each array has 60 values. I'm still noodling out how to best put this together... I need still need to manage time in all this for labels on the charts, but the time element is going to be synced across alll of the charts, so I've been playing around with updating the labels and horizontal values manually..

So in terms of Flex 2, would it be able to possibly handle this amount of data effectively since it uses flash 8? It sounds like you are saying that 1.5 has trouble displaying that amount of data because of ram usage problems? does that same problem exist in flex 2? Is there a max on how much memory flash player 7 is able to use effectivly? is that max much larger in flash 8.5 player? It sounds to me like it might be easier to port this thing to flex 2 than it would be to try and plug in to flash 8 bitmap features and draw my own graphs. as far as data points, well, it's 200 machines * 60
RE: [flexcoders] Performance question - please help!
Gordon, thanks for the response.
i guess what I was wondering was if it'd be better to
write up a class for data storage or just to use a
regular object...
ie myDataStore:Object and then:
myDataStore[mychart+1] = new Object();
then a lot more stuff and objects added... ie..
storing a ton of data...
or is it better to obfuscate this into a class
ie..
myDataStore = new DataStore(mychart+1);
Does it make a difference to the performance of the
application? so for example, when using the class do
you avoid any potential access locks? or are there no
access lock problems with either one of these? The
problem i'm facing is that I need to be able to move a
large amount of data into the system where i could be
trying to access the same variables at the same
time...
which brings up an at what point along the line does
variable locking take place?
so for example, if i have an extended variable
structure with sub objects and arrays, if two threads
try to update the same value, where does the locking
occur?
so for example:
myChartObj.myarray[3].property
if two threads try to update property, does it lock
you out of myarray until the update goes through or
does it lock you out of myChartobj? or does it only
lock property?
Thanks!

In AS3, you should declare a non-dynamic class for
your data items
rather than using untyped Objects. For example,
don't use data items
like
{ foo: 100, bar: 200 }
Instead write
new DataItem(100, 200)
where
class DataItem
{
function DataItem(foo:int, bar:int)
{
this.foo = foo;
this.bar = bar;
}
var foo;
var bar;
}
A non-dynamic class like DataItem takes a lot less
memory and you can
access foo and bar faster on it.
A plain Object is basically a name/value dictionary
where AS3 has to do
a name lookup in a hash table.
By contrast, a non-dynamic class is laid out
compactly in memory so that
AS3 knows that foo is at offset 4 from the beginning
of the data item in
memory, bar is at offset 8, etc. It can then read
and write them quickly
without any lookup.
When you use a non-dynamic class, each int, uint,
Boolean, and object or
string reference will take up 4 bytes, while each
Number will take up 8
bytes. Each instace also has a 16-byte header for
keeping track of what
class it belongs to, etc. There is also some
rounding up because the
memory manager allocates only chunks of certain
sizes.
