In the original post, you had 3 class vars  You still need those.
@Embed is compile time, so you have to embed the 3 images like you had
it at first, then the code I showed will choose one of the three
variables.

I have tried what you suggested but the image is not displaying. I have
added a text field into the custom component - this is displaying the
correct value. But it is not displaying any image - just a broken image
icon.

 

Here is the code for my custom component:

I am creating a datagrid that uses a custom component in an item

The data grid columns are created dynamically. I can't figure out how to

The symbol names are the same as the value for xmlColumn.localName();

Hello everybody.

I am developing a system for use of sockets to a telnet server on port 6677.
Locally, everything goes fine, even creating a projector(exe).

But when it goes online, it don´t connect because some kind of
crossdomain error.

The problem is that I don´t have access to the 80 port of the server,
so my webserver is on 6680 port.

I try use:
Security.loadPolicyFile("http://servico.servidor.com:6680/crossdomain.xml 
 "); 

And also:
Security.loadPolicyFile("xmlsocket://servico.servidor.com:6680/crossdomain.xml");

But, for some reason, he keeps giving me the sandbox error.

I did several alterations like:
Security.allowDomain(host +":6680")
Security.allowInsecureDomain(host +":6680");
Security.loadPolicyFile("xmlsocket://"+ host
+":6680/crossdomain.xml");
Security.loadPolicyFile("http://"+ host +":6680/crossdomain.xml");

But still, nothing.

Somebody have any idea?

Re: [flexcoders] Adding buttons to an Accordion header

[Doug McCune]

I might try to do a full post about this soon, but you can try checking out
the CanvasButton component in FlexLib. Basically this is a subclass of
Button that works like Canvas, so you can easily add whatever children to it
that you want. So you would use that to create your header renderer, which
you can set as a header renderer because it actually subclasses Button. You
can get the FlexLib components here: http://code.google.com/p/flexlib/

Hopefully that makes some sense. I'll try to write up a post soon since I've
seen this question asked multiple times.

RE: [flexcoders] Can I use Flex to create flash widgets? that are embedded in HTML/JS web-app?

[Alex Harui]

You can use Flex to create things not based on the Flex Framework and
make really small swfs, but you can't make swcs that will work in Flash
Authoring.

 

To make small widgets and swfs, you can subclass Sprite.

RE: [flexcoders] How to change positions of Alert popups in SHOW_ALL mode

[Alex Harui]

If I remember correctly, to get the scaling stage modes to work, you
have to make sure the application lays out at the same size as the
original stage.  I think you have to specify the size in the
mx:Appication tag, customize the HTML wrapper so it doesn't fix the
size, then make sure your layout fits in the size you specified.
Otherwise, things get out of whack.

[flexcoders] DelegateFactory

[Sammi]

Hi,

 

Am am creating a Cairngorm app that needs to support the API of a number of
similar online webservices.  All the webservices supply the same
functionality - just in a slightly different way.

 

My idea is this.  Use the FactoryPattern for the Delegates.  So when a
Command needs a delegate it calls the Factory and the factory supplies the
command with a delegate.

 

So the command needs a LoginDelegate.  It gets a
LoginDelegateForWebServiceA(), because the user has previously configured
the app to use web service A.

 

I am just so new to actually applying design patterns.  I have read many
articles and books (Head first Java books are GREAT!) so I understand the
concept.  I just haven't used it much so I am not sure if my idea is any
good.

 

Is this the way to go?  Can you point me at any good articles on how to
support multiple "backends"?

 

Best,

Sammi

What if the transition is just a simple fade from one skin to the
next. Does that make things any easier? The Button class has a
transitions property, so why can't that be leveraged?

[flexcoders] Adding buttons to an Accordion header

[kundigee]

I am dynamically creating an Accordion at run time.  I place a new 
panel in the Accordion which generates a new Accordion header that I 
attribute an icon to.  All good so far.  I need to dynamically place +/-
 buttons on the right side of each header to give the user the ability 
to replicate, or delete the panel/Accordion component.  I can't seem to 
addChild to the header with a child button.  The Accordion header is a 
button itself and not a container.  I started to create a custom MXML 
module extending Button, which I intended to substitute via the 
headerRenderer if I could work something out, but that also will not 
allow me to drop anything onto the component, as it is not a container.

Is there any way to do what I am trying to accomplish?

[flexcoders] How to change positions of Alert popups in SHOW_ALL mode

[george_w_canada]

In Flex the SHOW_ALL mode couldn't function correctly for default
popups, like Alert. I didn't find a way to fit them in center of
browser screen automatically. Occasional Alert popups (usually server
side errors) not belong to any views so to make an customized version
of Alert class will cost lots of time to dig. Any suggestions?

Thanks a lot!

[flexcoders] httpservice and crud

[nylarch]

noob question alert.

Just starting on flex.   I'm doing a simple CRUD page working with a calendar.  
 Do I need 
to do seperate HTTPService components for the different CRUD operations or is 
it possible 
to dynamically pass in requests to one service since I'm doing all of the 
operations on the 
same backend php page.

i.e. do you need to seperate:




{fmtDate.format(dateChoose.selectedDate)}






{fmtDate.format(dateChoose.selectedDate)}
<_update>true




or can I dynamically pass in the in "update=true" and just use one service for 
both Get and 
Update.

Thanks.

[flexcoders] Custom AS3 component, on stopDrag, everything disappears?

[mrand02]

I have a draggable part of my component (that extends Panel, if it
matters), that seems to work fine while dragging.  I can click on the
titleBar of the Panel and the Panel drags around the screen as you'd
expect a draggable window to do, but after I release the mouse button
and this function here gets called, the entire panel just disappears.
 I've tried stage.invalidate() and evt.updateAfterEvent(), they both
do nothing.  Any suggestions?  Never seen this happen before...

public function onRelease(evt:Event):void
{
if (_bIsDraggable)
{
this.stopDrag();
}
}

[flexcoders] HTTPService: Request timed out

[mitek17]

Hi all,

I've got an intermittent problem with HTTPService fetching data from
Apache2/PHP5 server over an SSL connection.

Sometimes (2-6 out of 200 requests) the response from server never
reaches the client back. Server logs show that the response has been
sent. The problem is in the browser or in my gut feeling in the
HTTPService itself.

I've already done the following:

1. variable URL like page.php?nocache=
2. PHP sends a header which tells not to cache the response
3. new HTTPService object is created for each request (this step gave
me the best improvement)

This problem happens on ANY browser at the same rate (IE6,IE7, FF,
Safari).

The whole flex application is running over an SSL connection and all
the HTTPService calls are made to the relative server addresses.


I should admit, that in test environment (localhost) where we don't
have SSL connection it never happened. On the other hand localhost
connection and ADSL links to the live site are quite different things.


Does anybody know any ways of overcoming this problem?

Thanks in advance!


Cheers,
Dmitri.

RE: [flexcoders] insert / delete problems using FDS with hibernate

[Jeff Vroom]

Hi Carlos,

 

First of all, if you are not running the latest version LC DS 2.5.1 (FDS
was renamed to LC DS), it may help to upgrade as we've both fixed a few
problems and also improved the diagnostics.  

 

The best way to diagnose these problems is to turn on the debug logging
on the server (services-config.xml for the patterns Message.* and
DataService.*) and client (with the ) tag.  

 

Hibernate also has some nice debug logging which shows the SQL that is
generated which is nice as well.  

 

I haven't heard of any problems where deleteItem just silently does not
delete the object.  In some cases, there are rows which refer to the row
you want to delete and so the deleteItem will generate an error due to
the database integrity constraint.  This can happen in particular
because hibernate supports cascade="delete" behavior but DMS does not
have that yet.  In these cases, you may have to delete the related
objects before you delete the main object.  

 

In any case, the debug logs will show the details and so we can figure
out what is going on.  If the logs are too big to send to the list, feel
free to send them to me off list ([EMAIL PROTECTED]) and I can help you
out.

 

Jeff

Subject: [flexcoders] insert / delete problems using FDS with hibernate

 

Hi everyone,

I'd be very thankful if anyone could help me with this problem 
because I got stuck on it for several weeks.

I'm developing a FDS application with database connection and I've 
mapped a relational database to POJO's with Hibernate (using 
hibernate tools). I'm experiencing a lot of problems when I try to 
insert and delete items using the hibernate assembler. Here is my 
situation.

My database, which represents information about cars, contains five 
tables:

MODEL
id
engine
transmission
cab 
bed 

MODEL_PACK
model_id
pack_id
inclusion_type

PACK
id
name 
category

MODEL_COLOR
model_id
color_id

COLOR
id
extColor
intColor

The AS classes that represent this schema:

Model.as

id:int;
engine:string;
transmission:string;
cab:string;
bed:string;
colors:ArrayCollection;
packs:ArrayCollection;

ModelPack.as

id:ModelPackId;
model:Model;
pack:Pack;
inclusion:String;

ModelPackId is a custom class to store the composite primary key 
which is mapped to the corresponding java POJO.

Pack.as

id:String;
category:String;
name:String;
models:ArrayCollection;

Color.as

id:String;
extColor:String;
intColor:String;
models:ArrayCollection;

The corresponding destinations in data-management-config.xml:


...


..


.








...


...

.

As you can see the relationships are bidirectional. 

For example I have the data service to manage the operations in the 
front end and a datagrid:





and a button:



The callback function only uses the hibernate assembler to delete the 
model:

models_ds.deleteItem(modelList.selectedItem);
models_ds.commit();

It seems that the operation is performed succesfully but then when I 
check the database or reload the application the model that I've 
tried to delete is still there with its corresponding packs and 
colors. Sometimes the application throws a runtime error about 
synchronization. I've tried to remove the relations in the AS classes 
because I think that the problem have to do with the relations 
between classes and it works but in this case the application doesn't 
meet my requirements and the delete operation is more complex. 
Similar problems happen when I try to add Items.

I've tried a lot of solutions to fix that problem (remove relations, 
convert them to unidirectional instead of bidirectional...) and I'd 
be deeply grateful if anyone can show me the procedure to add and 
delete items in that scenario. I've also thought that I could have 
missed any tag like "cascade" in the hibernate mapping files but I 
haven't tried this solution because I don't know what does it exactly 
mean.

I have heard that the hibernate assembler has some bugs and in some 
circumstances it doesn't work properly. Could anyone confirm that?If 
true what should be the alternative solution? It's very important for 
me because this is a small part of my dissertation and I can't 
continue because I got stuck on this issue.

Thanks a lot in advance,

Carlos

 

[flexcoders] Re: Multiple Axis in Flex 3 FLEX CHART

[reflexactions]

The example you give is not what is usually meant by a "multiple axis" 
chart it is more a "multiple chart" chart!

Multiple Axes refers to displaying several overlayed data series that 
use more than one axis in the same position i.e. two overlayed lines 
charts which have different scales shown with two Y Axis placed on the 
left of the chart.

You want to have several different charts stacked above each other 
sharing a common X axis.

With Flex Charts there is no built in way to achieve that but you can 
create more than one chart, place them in a VBox to stack vertically. 
You would then need to customise the charts to ensure the X axis scales 
were the same and to hide the XAxis for all but the main chart. 



FYI In XPCharting for Flex we have a built in SubChart that 
automatically does exactly this, it allows you to add multiple sub 
charts which are displayed stacked underneath the main chart sharing a 
common XAxis and only one chart displays the shared XAxis. You can see 
an example here 
http://www.xpcomponents.com/flex/examples/StockChartExample2/StockChartE
xample2.html where we use the subcharts to display volume and RSI below 
the main stock chart. You can control the heights of the various 
subcharts individually.

Therein lies the entire problem.  Discontinuities are an artefact of a

The whole problem would go away if we counted in base pi and went back

[flexcoders] Re: Overriding ValueObjects class

[simonjpalmer]

My first question is what are you trying to achieve by duplicating the
title variable in the subclass, it would on the face of it seem a
little pointless?   If you need to titles use an array or call them
different things so as to disambiguate them.

However, have you tried writing a setter or getter on the subclass

I think there is also an override keyword you could investigate.

Best solution is to design your objects in such a way that avoids
these sorts of clashes.

RE: [flexcoders] ComboBox SelectedIndex HELP!

Binding to functions is tricky.  It doesn't know when its value changed.
Binding to something that does is better.  The function probably gets
run at init time and errors which is eaten by Binding then never knows
that the results came back.  I would set selectedIndex in the results
handler.

RE: [flexcoders] Math.cos...?

[Gordon Smith]

Here is what the Ecmascript spec 
(http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf 
 ) 
has to say about methods like Math.cos():

The behaviour of the functions acos, asin, atan, atan2, cos, exp, log, pow, 
sin, and sqrt is not precisely specified here except to require specific 
results for certain argument values that represent boundary cases of interest. 
For other argument values, these functions are intended to compute 
approximations to the results of familiar mathematical functions, but some 
latitude is allowed in the choice of approximation algorithms. The general 
intent is that an implementer should be able to use the same mathematical 
library for ECMAScript on a given hardware platform that is available to C 
programmers on that platform.

Although the choice of algorithms is left to the implementation, it is 
recommended (but not specified by this standard) that implementations use the 
approximation algorithms for IEEE 754 arithmetic contained in fdlibm, the 
freely distributable mathematical library from Sun Microsystems (fdlibmcomment@ 
 sunpro.eng.sun.com). This specification also 
requires specific results for certain argument values that represent boundary 
cases of interest.

Note the phrases "intended to compute approximations" and "approximation 
algorithms". The "certain arguments values that represent boundary cases of 
interest" are specified as follows:

cos (x)

Returns an implementation-dependent approximation to the cosine of x. The 
argument is expressed in radians.
• If x is NaN, the result is NaN.
• If x is +0, the result is 1.
• If x is −0, the result is 1.
• If x is +∞, the result is NaN.
• If x is −∞, the result is NaN.

The http headers to control (and avoid the cache) come from the

In order to avoid cache you need to set the header "Pragma" with the

You should be using UIComponent if you know you won't need scrollbars,

Kind of a tangent, but if I had a ui component that had lots of child
ui components but I explicitly managed their position/layout, is there
something lighter weight than a Canvas I should be using? Should I
just be coding the object directly in AS, or is there an
MXML-supported component that's going to give me the freedom to do

Check out skin states in Moxie.  It was done for situations like this.

 

Otherwise, yes, you have to have a giant switch or really smart
per-state animations that look smooth no matter what the previous state
is.

Then how would you recommend implementing a button with transitions?
Buttons go through transitions (they are simple state machines), but it
doesn't appear to me (on admittedly casual inspection) that there's any
way to act on those transitions (in a way similar to how effects work). 

Sure, you can create a multi-frame animation for a given button state,
and you don't even have to do that in Flash, a programmatic skin could
do it with programmatic animation. I'm just not clear on how would could
correctly and accurately handle transitions. 

For example, I can happily plan an animation in the up state. And then
when the user mouses over my button, my skin switches to an over state,
and I can play an animation for that. But is there a way to skin the
*transition* from one state to another? 

I guess you could mirror the button's state machine and handle
transitions transparently to the button. With a programmatic skin, you
basically (in one style of implementation) have a giant switch statement
that determines if the skin is "up", "over", "down", "focus", etc. You'd
just need to update this switch to account for "transition states" and
animate appropriately. You'd have the awkward scenario of the button
entering the the "over" state immediately while the skin was in the
"up_to_over" transition state, which may or may not be a problem
depending on the complexity of the animation. Is it possible to manually
control the states of a button or is it hardcoded to specific events
(mouse over, mouse down, etc.)?

One option would be to use the effects of the button to do the
transitions. Unfortunately, they don't appear to be customized for the
Button class, so I don't know if you'd step on stuff the Button class
does in regards to mouseOver, mouseOut, etc. 

To be honest, depending on the complexity of your visuals and the number
of these buttons you need in your UI, it may be quicker to just create
an mx:Canvas that looks like a button and use effects (if you need a
container with children, e.g. labels and images), or just create a
UIComponent directly and manipulate it (if you've got just images).

Of course, that does depend on the overhead of Canvas which is something
I've been curious about (and perhaps Alex could answer): does mx:Canvas
introduce much overhead to the UI (as compared to UIComponent)? I know
mx:Canvas does a lot of layout chores, but are they relatively cheap if
the children are relatively cheap ( e.g. a few fixed sized components
with fixed positions)?

Hmm, good question...

In the Flash IDE, you'd just create animations in each state
(transition is tricky, but you could easily have it play an animation
at the beginning of a state and loop).

In Flex, you could do it with a programmatic skin, but you'd be
responsible for juggling all the animation and state information.
Again, transitions would be difficult, i.e. Up to Down plays this

You could do that. But you cannot store PI or any other infinite  
sequence in the machine from which to perform calculations on.  
Getting a specific digit of PI, or something similar (say 22/7), is  
different than using it in a calculation.

[flexcoders] glow effect on component with border shifts insides of component

[blc187]

I have a component that I am using a glow effect for mouseover.
The component is an hbox with some labels and 2 images inside it, 
and a solid border around it.
However, when the mouseover triggers and the glow effect plays, the 
labels inside shift down a pixel or two.
When the border is removed, everything stays where it should on 
mouseover.

Anyone have any ideas why the shift?
Below is the mxml for the component (border of HBox mainBox is what 
can be removed to stop the shift)

Hi!

I have a skinned play button that needs to turn into a pause button

not, what is the recommended way to change the button skin when user
clicks it?

Appreciate the help!

I may take you up on this challenge- I've got this strange masochistic

It's not sloppy, it's just how floating point numbers work.  Try the
same thing in other programming languages and you still will not get
zero (unless they round the output).  For example, .NET reports the
result as 

6.12303176911189E-17.

The documentation's actually fairly clear on this: "The cosine of a 90

calculations using binary numbers, Flash Player will report a number
extremely close to, but not exactly equal to, zero."

 

Nevertheless, it seems... sloppy to me.

[flexcoders] Cache-Control header not working in HTTPService

[Guido]

Hi y'all,

I've been having this problem for a while now, and I've went by the docs on
RPC components time and time again, getting no solution for this.

I have an HTTP service and I need to guarantee that its results are not
cached by either the app or the browser.

My last attempt on this is:



When debugging the app, the service's HTTP header property is populated by
the URLRequestHeader, so I believe It's getting built adequately. Also, when
inspecting the AsyncToken returned by myService.send(), the message property
has its headers also populated by the URLRequestHeader.

The thing is that when I check for adequate reception on the server side, I
don't get the Cache-Control header at all.


Does anyone know how to make HTTP headers work for HTTPServices?

TIA,

Guido.

Re: [flexcoders] Cache-Control header not working in HTTPService

[Dan Todor]

Try adding current system time as a parameter to your request, it will avoid
caching.

Re: [flexcoders] Cache-Control header not working in HTTPService

[Scott - FastLane]

If you have control of the server side of your project, you could ask 
them to include the cache in their response header... I believe that is 
the way it is supposed to work.  The server indicates that the content 
it is returning is dynamic in nature and should not be cached.  While 
adding the current time to each of your requests as a parameter will 
avoid caching, it is a bit burdensome if you have a large system to 
implement.  Note also that the no-cache response header is ignored by 
IE/flashplayer when your request is over https as described here 
http://blog.fastlanesw.com/?p=9.  Note: I also describe the workaround 
that I use to get around this issue.

Kind of a tangent, but if I had a ui component that had lots of child
ui components but I explicitly managed their position/layout, is there
something lighter weight than a Canvas I should be using? Should I
just be coding the object directly in AS, or is there an
MXML-supported component that's going to give me the freedom to do
composition without the weight of a container?

The thing is on my server side checkings I don't get the HTTP headers at all

It's not a problem of the HTTP parameters, it's got to do with the HTTP

Re: [flexcoders] Math.cos...?

[Troy Gilbert]

ML == MathLab? Well, of course MathLab would go to great trouble to minimize
this issue as much as possible, including doing its calculations in such a
way that it preserves fractional representations and evaluates by truly
combining expressions and doing simplification, as opposed to rote
calculation to a numerical value then substitution.

I also wouldn't be surprised if ML didn't explicitly handle common Pi
constants. While it absolutely wouldn't be an optimization for standard trig
functions (it doesn't take many lookups on modern CPU's before just letting
the floating-point unit do its thing to be faster -- and if you start
choosing 'shortcuts' you'll never make everyone happy).

Re: [flexcoders] Buttons in Flex !

[Troy Gilbert]

Then how would you recommend implementing a button with transitions? Buttons
go through transitions (they are simple state machines), but it doesn't
appear to me (on admittedly casual inspection) that there's any way to act
on those transitions (in a way similar to how effects work).

Sure, you can create a multi-frame animation for a given button state, and
you don't even have to do that in Flash, a programmatic skin could do it
with programmatic animation. I'm just not clear on how would could correctly
and accurately handle transitions.

For example, I can happily plan an animation in the up state. And then when
the user mouses over my button, my skin switches to an over state, and I can
play an animation for that. But is there a way to skin the *transition* from
one state to another?

I guess you could mirror the button's state machine and handle transitions
transparently to the button. With a programmatic skin, you basically (in one
style of implementation) have a giant switch statement that determines if
the skin is "up", "over", "down", "focus", etc. You'd just need to update
this switch to account for "transition states" and animate appropriately.
You'd have the awkward scenario of the button entering the the "over" state
immediately while the skin was in the "up_to_over" transition state, which
may or may not be a problem depending on the complexity of the animation. Is
it possible to manually control the states of a button or is it hardcoded to
specific events (mouse over, mouse down, etc.)?

Math.cos() (and every other trig function) should check the argument being
PI (or any other of its own constants) before calculating, since it would
better reflect the mathematical function and maybe even save up on some
performance.

RE: [flexcoders] Re: Reduce size of my module! Really boring....

[Alex Harui]

The host generates a link-report that the modules load-extern so that no
classes in the host are in the modules.

 

If you use the framework as an RSL, then compiling with that option on
should flush all of those classes as well.  If you generate link-reports
from your modules, you can see if everything that should be removed got
removed.

 

The shared code example on my blog also addresses how to deal with a set
of modules that share code among themselves.

[flexcoders] Overriding ValueObjects class

[nhid]

Hello,

Lets say I have a VO class Bar.as to be extended from Foo.as VO class.  I
get this error at variable "title" (see code below):

Overriding a function that is not marked for override.

How do I resolve this?  I saw Adobe's link saying I should remove [Bindable]
from base class, I did but that did not resolve the problem.  Any suggestion
is appreciated.

thank you.

**
// Foo.as
package com.xyz
{
  [Bindable]
  public class Foo
  {
public var title:String;
  }
}

// Bar.as
package com.xyz
{
  [Bindable]
  public class Bar extends Foo
  {
public var description:String;
public var title:String;
  }
}

RE: [flexcoders] air namespace (adobe)

[Gordon Smith]

No. This decision is consistent with the fact that the AIR team has put
their new classes like File into the flash.* package.
 
Both decisions are motivated by the fact that it's hard to know what
classes will exist on which platforms in the future. For example, the
Flash Player for mobile devices -- which isn't AIR -- may have a File
class. So our rule is that packages do not indicate the platform.

RE: [flexcoders] Buttons in Flex !

[Alex Harui]

Contianers are very heavy.  There's actually quite a bit of logic making
a button feel like a button.  You can approximate it with Canvas and
states, but you might miss some things.  It really depends on quality
and what you're comfortable with.  If you don't know Flash, it could
take you a while to figure out how to create a symbol.

One option would be to use the effects of the button to do the
transitions. Unfortunately, they don't appear to be customized for the
Button class, so I don't know if you'd step on stuff the Button class
does in regards to mouseOver, mouseOut, etc. 

To be honest, depending on the complexity of your visuals and the number
of these buttons you need in your UI, it may be quicker to just create
an mx:Canvas that looks like a button and use effects (if you need a
container with children, e.g. labels and images), or just create a
UIComponent directly and manipulate it (if you've got just images).

Of course, that does depend on the overhead of Canvas which is something
I've been curious about (and perhaps Alex could answer): does mx:Canvas
introduce much overhead to the UI (as compared to UIComponent)? I know
mx:Canvas does a lot of layout chores, but are they relatively cheap if

with fixed positions)?

Hmm, good question...

In the Flash IDE, you'd just create animations in each state
(transition is tricky, but you could easily have it play an animation
at the beginning of a state and loop).

In Flex, you could do it with a programmatic skin, but you'd be
responsible for juggling all the animation and state information.
Again, transitions would be difficult, i.e. Up to Down plays this
animation, but Up to Over plays this animation (or whatever
transitions make sense).

If you wanted to keep things as "high level" as possible, by which I

use effects/behaviors.

RE: [flexcoders] Math.cos...?

[Gordon Smith]

In addition to Math.PI not being able to store the exact value of pi,
the computation of trig functions involves approximations. For example,
one definition of a cosine is in terms of an infinite series, and a
computer can't calculate an infinite number of terms. Even if the
argument passed to Math.cos() is exact, the result generally won't be.

That's pretty much it. 

To a computer Math.cos(Math.PI/2) is not 0. It's really close to 0,
because PI is an infinite sequence and a computer can "only" store it as
a double precision floating point number (ie, a fixed value).

What you get back from this calculation is the error bound of the
computer basically, which you can then use for  numerical calculations,
ie, MathLib.ERROR_BOUND = Math.cos(Math.PI/2). Then you can feasibly use
if you need numerical accuracy.

IE, if result == MathLib.ERROR_BOUND, result = 0.

Numerical accuracy in AS2 is not equivalent to that of AS3. I ran into
this while porting the Mersenne Twister algorithm to AS2 - I couldn't
even store 2^32 as a hex value in AS2 (0x1, which equals
4294967296).

At least we can be somewhat numerically accurate now...

good luck,

jon

Hello everybody.

I am developing a system for use of sockets to a telnet server on port 6677.
Locally, everything goes fine, even creating a projector(exe).

But when it goes online, it don´t connect because some kind of
crossdomain error.

The problem is that I don´t have access to the 80 port of the server,
so my webserver is on 6680 port.

I try use:
Security.loadPolicyFile("http://servico.servidor.com:6680/crossdomain.xml 
 ");

And also:
Security.loadPolicyFile("xmlsocket://servico.servidor.com:6680/crossdomain.xml 
 ");

But, for some reason, he keeps giving me the sandbox error.

I did several alterations like:
Security.allowDomain(host +":6680")
Security.allowInsecureDomain(host +":6680");
Security.loadPolicyFile("xmlsocket://"+ host
+":6680/crossdomain.xml");
Security.loadPolicyFile("http://"+ host +":6680/crossdomain.xml");

But still, nothing.

Somebody have any idea?

Not sure why you're seeing a difference between AIR and Flex (I would
assume they're both using the Flash Player, but I guess AIR uses a
special build of the Flash Player to ease security issues). Hopefully
someone else can address the AIR issue.

Looking at the specific image, though, I would urge you to use a
different format for your image data. For high-resolution B&W imagery
(grayscale is just masking the reduced resolution) you should either
use a specialized renderer (store the image as a ByteArray at either
1-bit or 8-bit depending on the zoom level you want, then render out
tiles manually), or if you can get the data in this format from the
source, store it as vectors (mxmlc can compile SVG into vector shapes
in an SWF, and you can probably find a vector to SVG converter for
whatever the originating SVG format is).

[flexcoders] Need some help with Tooltips and Flex Component Kit

[Mark]

I have a Flash that has 2 items for use by my Flex app.  One is a 
flat circle to plot some points on and the other is the dot which 
will be those points.  In flex I'm duplicating and position these 
points from the data within my ArrayCollection.  That is woking just 
fine, but I have a tooltip on my points that takes a while to 
appear.  I have a trace on that function that returns the info right 
away, but the tooltip is very slow.  But if you roll over it anytime 
after it has been created the first time it works properly.  I think 
my AS is bad and was hoping someone could tell me what is wrong.

Here's what I have.



on the Circle I have a function that creates each point - 

public function plotRadarPoints() {

[flexcoders] Changing the image in a custom component item renderer

[Paul Steven]

I am creating a datagrid that uses a custom component in an item renderer to
display one of 3 images (symbols of an embedded swf)

 

The data grid columns are created dynamically. I can't figure out how to set
the value of imagePath inside this custom component. 

 

The symbol names are the same as the value for xmlColumn.localName();

 

Any help really appreciated!!

 

 

e.g

 

dgc = new DataGridColumn();

dgc.headerText = xmlColumn.localName();
dgc.itemRenderer=new ClassFactory(statusComponent); 
dgc.dataField = xmlColumn.localName();

 

My custom component is as follows:

Re: [flexcoders] Buttons in Flex !

Hmm, good question...

In the Flash IDE, you'd just create animations in each state
(transition is tricky, but you could easily have it play an animation
at the beginning of a state and loop).

In Flex, you could do it with a programmatic skin, but you'd be
responsible for juggling all the animation and state information.
Again, transitions would be difficult, i.e. Up to Down plays this
animation, but Up to Over plays this animation (or whatever
transitions make sense).

If you wanted to keep things as "high level" as possible, by which I
mean doing it declaratively in MXML, you'd probably end up just
skipping a subclass of mx:Button and instead subclass mx:Canvas and
use effects/behaviors.

As Tom said, the answer is no, you can't do that, and for very good
security reasons.

>From a usability perspective, the answer would still be no, you
*shouldn't* do that, for very good usability reasons.

My question is, why do you want to do that? Why would it ever be smart
to *prevent* your user from have more control over their machine and
their interaction with your product?

Interestingly, this issue used to come up all the time in the DirectX
world with folks asking how to prevent users from ALT+TAB'ing away
from their game, or to prevent users from using CTRL+ALT+DEL, etc...
and the question was always, "why?"

[flexcoders] Sandbox/Crossdomain problem on connecting Socket with webserver on port 6680

[Rogerio Gonzalez]

Hello everybody.

I am developing a system for use of sockets to a telnet server on port 6677.
Locally, everything goes fine, even creating a projector(exe).

But when it goes online, it don´t connect because some kind of
crossdomain error.

The problem is that I don´t have access to the 80 port of the server,
so my webserver is on 6680 port.

I try use:
Security.loadPolicyFile("http://servico.servidor.com:6680/crossdomain.xml";);

And also:
Security.loadPolicyFile("xmlsocket://servico.servidor.com:6680/crossdomain.xml");

But, for some reason, he keeps giving me the sandbox error.

I did several alterations like:
   Security.allowDomain(host +":6680")
   Security.allowInsecureDomain(host +":6680");
   Security.loadPolicyFile("xmlsocket://"+ host
+":6680/crossdomain.xml");
   Security.loadPolicyFile("http://"+ host +":6680/crossdomain.xml");

But still, nothing.

Somebody have any idea?

Regards!

[flexcoders] Re: FABridge and Safari

[Richard Rodseth]

Sorry to repeat the question. I enabled the debug menu in Safari and
the JavaScript console reports an error "undefined value" at this
line:

var flexApp = FABridge.flash.root();

The code works fine on Firefox and IE. I'm using the FABridge included
with Moxie B1. Is there a later or earlier version I should be using?
Perhaps it only works with bridgeName set? (I'll try that). Thanks.

Re: [flexcoders] SOAP Service Issue, kind of a big bug

[Paul deCoursey]

Alright, I've figured it out.  I was trying the property value to 
represent the text content of the element, but flex looks for the name 
of the element as the text content. Not exactly intuitive, but 
reasonable.  Some other issues have arisen however.  I have a response 
that looks like this:





And the profile Element is unbounded, and there can be none at all. I've 
noticed that if there are several, like 2-7 (I have not tried more) then 
the response objects that flex decodes look fine.  But if there is one, 
then I get an array for the only element is null, where is the Object?  
Any ideas?

RE: [flexcoders] Flex component kit problem

In Flex, components are constructed, then their properties are set.  I
would expect you to have the same problem in Flash if you did

 

Var foo = new MyComp()

Foo.label = "bar"
