[flexcoders] Re: TabNaviigator tabBar index doesn't update on selectedIndex change

[rleuthold]

Hi Jeff,

Have you found a solution to this, cause I'm having exactly the same problem, 
and didn't 
found a way to solve it.

 I can work around this by extending the component (I think) but I
 shouldn't have to do this - perhaps I'm missing something on how to best
 approach it.

[flexcoders] Inline EventListener in MXML tags - confusing description in Developers guide.

[florian.salihovic]

Quoted from Adobe Flex Developers Guide, page 78

However, it is best practice to use the addEventListener() method.
This method gives you greater control over the event by letting
you configure the priority and capturing settings, and use event constants.
In addition, if you use addEventListener() to add an event handler, you can
use removeEventListener() to remove the handler when you no longer need
it. If you add an event handler inline, you cannot call removeEventListener()
on that handler.

 - End of Quote -

What i think is a little bit confusing is, that it's said that inline 
EventListener can't be 
removed? Or is it just a little bit unluckily expressed? Why can't i just call 
removeEventListener in ActionScript on the type of event declared in MXML?

[flexcoders] Mapping LCDS from Java to AS

[berenger_kc]

Hello,




I use LCDS 2.6 and JBoss 4.2.2, I start to work with these technologies
and have a problem with the data mapping between java and actionscript.




I will try to be as clear as possible to express my problem :



Server side, I use the java.util.Vector class and my design is

OBECT_A extends VectorOBJECT_B

OBJECT_B  /*this object has an attribute called anObjectDList  with the
type OBJECT_C*/

OBJECT_C extends VectorOBJECT_D

OBJECT_D



If from the client side I use the arraycollection type, this mean that
anObjectDList is not like an OBJECT_C type and the fill method fill an
object that is an ArrayCollection and not an OBJECT_A type. Then,
everything happened well, but I loose all my design. In fact the
OBJECT_A and OBJECT_B type are no more useful in the client side.



Then what I did is to extends the OBJECT_A et OBJECT_C to the
ArrayCollection. But now the problem occurs, I can see the content of
the Object_A and Object_B, but the Object_C is now empty. There is a
conversion error : conversion from mx.collections::ArrayCollection to
test.datamodel.OBJECT_C impossible



Does it mean that the mapping could not exist with object extended from
ArrayCollection ? DO we have to use strictly the ArrayCollection type, I
mean no inherited classes from this type ?


Thanks for your answer.

[flexcoders] AdvancedDataGrid + printing issue

[Kuldeep Atil]

Hi All,

Is there any way(method) by which we can get the expanded nodes of 
advanceddatagrid while printing irrespective of the current (expanded) 
state of advanceddatagrid.

i.e. lets say i a collapsed ADG but when i click print button the 
printed ADG must have all the nodes expanded without really expanding 
the nodes of ADG in my application.

Thanks and Regards,

[flexcoders] Numbers gone crazy: 5 - 4.8 = 0.2000000000000018 ?

[b_alen]

Here is how I arrived at this:

var res:Number;

var a:Number = 5;
var b:Number = 4.8;

res = a - b;
trace(result:  + res + , a:  + a + , b:  + b);


The trace clearly shows that the value of a is 5, and the value of b
is 4.8. However the end result is clearly shown as 0.2018.

Ok, I wanted to create a workaround where I will make sure that b is
really 4.8, and I used toPecision() method.

var b1:String = b.toPrecision(2);
var b2:Number = Number(b1);
trace(b1:  + b1 + , b2:  + b2);

res = a - b2;
trace(result:  + res + , b1:  + b1 + , b2:  + b2);


Again with same result. b2 was traced as 4.8, but the end result still
showing 0.2018. As this can of course break all further
calculations I had to make sure result is really holding a value that
it should, based on all mathematical logic. So I did this:

var res1:String = res.toPrecision(2);
res = Number(res1);

trace(result:  + res);

I got the expected result and the value of res is now 0.2.

This is however very ugly, in case I'm not doing something wrong.
Every time we expect a floating point value in our calculation we have
to handle it to ensure the proper value is calculated, because what
Flash calculates is just wrong. Also, every intermediate calculation
has to be stored in a variable converted to String with toPrecision
and back to Number for future use. I really don't know how to properly
handle this and would appreciate any advice. Imagine the shopping cart
system with this sort of unpredictable behavior. 

For the end, here's one more weirdness:

var c:Number = 488.8;

trace(c:  + c +  , c.toPrec:  + c.toPrecision(2));


Traces out c: 4.8, c.toPrec: 4.9e+2




Thanks,

Alen

Re: [flexcoders] Re: Inline EventListener in MXML tags - confusing description in Developers guid

[Johannes Nel]

you could compile with the -keep option to see what is output underneath the
covers.
and then what i think might be the case
pure speculation follows
consider that the mxml gets converted to as. now in mxml you could have
something event={a=1}
or
something event=function(event,'sdfdsf')
or...
now if i was to write a converter for something like this i would wrap the
function which invokes whatever the user specified (i am not certain if this
is the case) in order to make my approach as flexible as possible

RE: [flexcoders] air sqlite example with BLOB datatype

[Jim Hayes]

I don't have an example to hand, but from memory :
 
Storing images is a question of reading the original image file as a
bytearray and inserting that byteArray varaible into a blob field in the
database.
 
Reading is much the same, select the record and read/cast it into a
byteArray.
 
It's then possible to use Loader to convert that into an image (Some
details on that @  http://ifeedme.com/blog/ )
 
Hope that's enough to get you going (it all worked fine for me)

[flexcoders] Re: Anyone have a good resource on singletons?

Hi,

here I got a way to do it here

note that a lot of people will debate on how to define singleton in AS3,
I don't say that the solution I mention above is the best but imho
it's the most standard-way to do it and the closest to the AS3
language (and if someone want to debate that come with good arguments,
just saying duh Java use getInstance() so we should do the same that
will not qualify as a good argument)

[flexcoders] Numeric values drawn from a database, always int?

[bredwards358]

So far so good in the application currently in development, I feel
like I'm in the home stretch. However something has come up which
could prove to be a roadblock in the near future. There are some
values which need to be totaled up and some of those need decimals.
Now I realize that the int datatype doesn't deal with that, and the
only thing I've seen thus far which fills the same purpose as a double
datatype is the Number datatype. However when I try something like this:

for(var i:int; i  n; i++)
{
total2 += dgProvider[i].ProductList;
total3 += dgProvider[i].Cost;
}

If total2 and total3 are of the Number datatype, the result will
display as NaN or Not a Number. This works fine however if total2
and total3 are declared as int. What I'm wondering is, are numeric
values drawn from a database (SQL Lite here) automatically cast as
int? Even if the database has them as NUMERIC and not INTEGER? If so,
then would I be able to work around this by doing something like this?

for(var i:int; i  n; i++)
{
total2 += Number(dgProvider[i].ProductList);
total3 += Number(dgProvider[i].Cost);
}

I'm just asking for some clarification on this before I finally get
around to it after finishing up a few things on this project. Thanks
in advance,

Re: [flexcoders] Re: Numbers gone crazy: 5 - 4.8 = 0.2000000000000018 ?

[Alen Balja]

Yes, toFixed() is a better option. It still does not solve the problem as we
don't know to what value to fix the numbers to achieve consistent behavior.
In practice using something like toFixed(8) for every Number should do the
job, but then again we can't be sure.

I also found this blog that seems useful:

RE: [flexcoders] Numeric values drawn from a database, always int?

I think you can find the answers here :

(I'd been meaning to look this up in any case, you just prompted me! Not
finished reading it all as yet.)

Subject: [flexcoders] Numeric values drawn from a database, always int?
 
So far so good in the application currently in development, I feel
like I'm in the home stretch. However something has come up which
could prove to be a roadblock in the near future. There are some
values which need to be totaled up and some of those need decimals.
Now I realize that the int datatype doesn't deal with that, and the
only thing I've seen thus far which fills the same purpose as a double
datatype is the Number datatype. However when I try something like this:

for(var i:int; i  n; i++)
{
total2 += dgProvider[i].ProductList;
total3 += dgProvider[i].Cost;
}

If total2 and total3 are of the Number datatype, the result will
display as NaN or Not a Number. This works fine however if total2
and total3 are declared as int. What I'm wondering is, are numeric
values drawn from a database (SQL Lite here) automatically cast as
int? Even if the database has them as NUMERIC and not INTEGER? If so,
then would I be able to work around this by doing something like this?

for(var i:int; i  n; i++)
{
total2 += Number(dgProvider[i].ProductList);
total3 += Number(dgProvider[i].Cost);
}

I'm just asking for some clarification on this before I finally get
around to it after finishing up a few things on this project. Thanks
in advance,

[flexcoders] Re: Runtime CSS and SWF is not a loadable module

Was anybody able to view the css styles swf that I posted earlier?  I'm still 
unable to 
implement runtime css because of the SWF is not a loadable module error.  Any 
further 
help would be greatly appreciated.

Thank you,

 Hi Tracy,
 
 I'm confident that FB3 can find the style swf since the following is
 printed to the console:

 Still not sure how to verify that the style1.swf is actually a style swf
 (though I have no 
 reason to believe that it is not).

  Hello,
  
  I'm trying to implement runtime css in my flex application. I have
  compiled my css file 
  into a swf with mxmlc
   mxmlc style1.css
  
  Then I load the resulting style1.swf on Application creationComplete:
  
  mx:Application xmlns:mx=http://www.adobe.com/2006/mxml
 http://www.adobe.com/2006/mxml

 layout=vertical
 
 creationComplete=StyleManager.loadStyleDeclarations('../assets/style1.s
  wf', true, 
  true)
  
  But when I debug this in Flex Builder 3, I get an error (see below)
  saying that my 
  style1.swf is not a loadable module. I looked around online and in
 this
  forum and it seems 
  that this message is security-based, which is puzzling to me because
 all
  files are local in 
  my example. I am not loading a style file from another domain.
  
  My directory structure (on OS X Leopard) is:
  testRuntimeCss\
  assets\
  style1.css
  style1.swf
  src\
  testRuntimeCss.mxml
  
  I have tried this with the Compile CSS to SWF option both checked
 and
  unchecked (right 
  click on style1.css). 
  
  What gives?

[flexcoders] Animated dashed lines

[havardfl]

In a project I'm working on I would like to represent data flowing
through the system with dashed/dotted lines moving between two or more
points.

I've done one implementation using the lineGradientStyle function to
create dashes. This works, but I'm not pleased with the CPU load while
the script is running. I'd like to draw 100+ lines, and my method of
doing it isn't cutting it.

Does anyone know a great way of drawing animated dashed/dotted lines
without using much CPU time?

Hi people!  Situation as follows:

MYARRAYCOLLECTION (Example fields)
- TITLE 
- URL

- TILELIST
  - DataProvider={MyArrayCollection}
  - ItemRenderer =MyRenderer


MYRENDERER.MXML
- LABEL (data.TITLE) (WORKS FINE)
- LINECHART

THe problem is: How can i filter linechart inside MYRENDERER.MXML the

I tried something like:

-DataProvider=Application.application.MyArrayCollection.(@Url=data.Url)}

but this throws me the following error:

wrote:

 you could compile with the -keep option to see what is output

 pure speculation follows
 consider that the mxml gets converted to as. now in mxml you could

 something event=function(event,'sdfdsf')

 now if i was to write a converter for something like this i would

certain if this
 is the case) in order to make my approach as flexible as possible
 

One difference between adding a listener inline and adding a listener 
in AS3 is that inline you have a choice of arguments...you can have 
no argument, an arbitrary argument, or send the event.  In AS3, the 
event is always passed.   If your function doesn't expect to get the 
event as its one and only argument, you will get a runtime error.

This does imply that whatever goes on in addEventListener, it is way 
stricter than what happens when you add the listener inline.  It 
would be nice if the finer points were documented.

Re: [flexcoders] Re: Anyone have a good resource on singletons?

[Troy Gilbert]

 I'm trying to find information on using singletons in AS3/Flex. I've
 got an .AS file set up but I'm having issues calling the data/functions
 within that function in other classes. Does anyone have a good resource
 on the web for creating and using singletons?

As others have probably pointed out, it sounds like you may be trying
to use a singleton to solve an architectural issue possibly not best
solved with a singleton. But, if singleton is appropriate...

Don't make it more complicated than it needs to be. Everyone seems to
do that with singletons, which is unfortunate since singletons should
be so rarely used anyway. Just create a class that creates and returns
an instance on first access, then returns that instance on further
access. If you're worried about other developers constructing multiple
instances of your class, then just include a test in the constructor
and have it throw an error or assert.

Don't worry about making it *impossible* to create multiple
instances... it's just not worth the effort. If people are determined
to use your classes incorrectly and disregard warnings and errors,
etc, then they're digging their own grave.

Here's the implementation I use:

public class Singleton {

  private static _instance:Singleton;

  public function get instance():Singleton {
if (_instance == null) _instance = new Singleton();
return _instance;
  }

  public function Singleton() {
if (_instance != null) throw new Error(This class is a singleton.
Instance already created.);
  }
}

Troy.

[flexcoders] Re: Would like to create a dynamic form

[valdhor]

Tim

Yes, it can be done but it ain't easy.

I have just completed an application that creates form items on the
fly from a database. The PHP code returns value objects with fields
including FieldName, FieldLabel, FieldType etc.

So, first, I create a custom class that extends Form. Then, in the
constructor, I ask for the field data with a RemoteObject call. Once I
get the data back, I loop through the value objects and create a form
field as specified...

for(var i:int ; i  FormFieldsArrColl.length ; i++)
{
   var theFormItem:FormItem = new FormItem();
   switch(currentFormField.FieldType) // currentFormField is my VO type
   {
  case textinput:
 var theTextInputItem:TextInput = new TextInput();
 addTextInputFormItem(theFormItem, theTextInputItem,
currentFormField);
   }
}

The addTextInputFormItem function looks like this...

private function addTextInputFormItem(aFormItem:FormItem,
aTextInputItem:TextInput, theFormField:MyFormField):void
{
   if(theFormField.Required) {aFormItem.required = true;}
   aFormItem.setStyle(fontWeight, bold);
   aTextInputItem.setStyle(fontWeight, normal);
   aTextInputItem.id = theFormField.FieldName;
   aTextInputItem.width = 300;
   aFormItem.label = theFormField.FieldLabel + :;
   aTextInputItem.text = theFormField.FieldDefaultText;
   aFormItem.addChild(aTextInputItem);
   this.addChild(aFormItem);
}

There are case items and functions for all the other field types
(TextArea, Checkbox and RadioButtons) but I will leave those
definitions for you to figure out ;-}

Then, once everything has been set up you need to add a submit button
and then loop through all the fields and validate them (Correct data
type, Values specified for required fields etc) and finally send all
this data back to the server.

Of course, I have extended mine even more with fields that depend on
other fields and animation to show different fields.

[flexcoders] Blank Images

I am testing something with Flex3 and need some guidance.

I have a security camera that I can only see as a jpeg 320x240 and I
am trying to get a flex program to display an image every 3 seconds.

I have used the image control and created a timer event to refresh
the image every 5 seconds.  
The problem is that the image blanks out during the reload, so in

What would be a good solution to remove the blank times?
URLLoader?, is there some part of the image controls to remove the
blank during load?

[flexcoders] Flex Dashboard

[gjessup1]

Hey all,
I have been watching this group for a while and figured many of you
could benefit from a project I started called the Flex Dashboard.
The google group is  http://groups.google.com/group/flex-dashboard

Its basically a database driven module loader. It is currently using
MSSQL Server as the DB, but the table script is available online, so
could easily be changed to use the DB of your choice. Its a work in
progress, but getting a community involved usually helps a project
grow much faster.

I am  using Weborb to invoke the DB calls using C#. This could be
changed. Would like to see it become very dynamic over time.

Please head over and have a look. Looking to create a community that
can make this a great product everyone can use.

RE: [flexcoders] Re: PopUpManager

[Alex Harui]

Background of the popup?  You specify that by making a selector of the
name of the MXML file that defines the popup.

 

 Backgorund of the app behind the popup?  You have to specify the
modalTransparency and related styles

[flexcoders] Re: Anyone have a good resource on singletons?

[Rick Winscot]

With regard  to Troy's comment on making it *impossible* to create
multiple instances... - I would add.. multiple instances shouldn't be
a huge problem unless you are using modules in your app. If you are -
it is quite important to make sure you watch that like a hawk.

 As others have probably pointed out, it sounds like you may be trying
 to use a singleton to solve an architectural issue possibly not best
 solved with a singleton. But, if singleton is appropriate...

 Don't make it more complicated than it needs to be. Everyone seems to
 do that with singletons, which is unfortunate since singletons should
 be so rarely used anyway. Just create a class that creates and returns
 an instance on first access, then returns that instance on further
 access. If you're worried about other developers constructing multiple
 instances of your class, then just include a test in the constructor
 and have it throw an error or assert.

 Don't worry about making it *impossible* to create multiple
 instances... it's just not worth the effort. If people are determined
 to use your classes incorrectly and disregard warnings and errors,
 etc, then they're digging their own grave.

 Here's the implementation I use:

 public class Singleton {

 private static _instance:Singleton;

 public function get instance():Singleton {
 if (_instance == null) _instance = new Singleton();
 return _instance;
 }

 public function Singleton() {
 if (_instance != null) throw new Error(This class is a singleton.
 Instance already created.);
 }
 }

   Hi Randy - thanks for the feedback!
  
   I was hoping to find a way to preserve the XML file without
   contaminating it with the private var novel:XML =  bit. That way I
   can create the XML file using my favorite XML generator (and use a
   validating XSD schema to make sure everything is correct). When the
   XML file looks good I can simply drop it into my Flex project -
   overriding the previous XML file - and everything should just
 compile.
  
   That approach would work if I was working in MXML using the mx:XML
   id=MyBooks source=books.-xml/ tag. I was hoping there was an
   equivalent way to do it when working purely with ActionScript .as
 files.
  
   Any ideas?

What's the best way to compile an XML file directly into
 ActionScript?
   
You can assign an XML literal to a variable as such:
   
var novel:XML = BOOKTITLE--My Book/TITLE--/BOOK
   
But it would be much better to have the XML in an externally
 managed
file. I'd much prefer to do something like:
   
var novel:XML = {include Books.xml;--};
   
But this doesn't seem to be allowed.
   
I could load the XML file at runtime but then I'd have to deal
 with
the asynchronous nature of the loading and I'd have to handle any
runtime errors if there was a problem - yuck!
   
If I was working in MXML I'd be able to do something very elegant
 such
as using the compile-time tag mx:XML id=MyBooks
  source=books.--xml/
   
So how do I include XML into ActionScript in a way that is as
 elegant
as it is for MXML?

Re: [flexcoders] Filter an ArrayCollection into an ItemRender

The syntax you tried is e4x (ECMAscript for XML) and only works with XML

http://www.boyzoid.com/blog/index.cfm/2006/10/19/Filtering-Data-in-Flex
or the filterFunction property of ArrayCollection in the Flex documentation.

[flexcoders] annotations on flex charts?

[flexcoders] How to display a total row on a DataGrid

Hello All,
Well, I'm stuck.  I've approached this about 3 different ways and have run
into (different) dead ends on all of them. I've tried using multiple
datagrids, which I got working fabulously, but setting the datagrid to width
100% does really wacky things with the column sizes.  I've also tried to use
the built-in Summary classes with the AdvancedDataGrid, but they seem only
to work with Grouped data. I could hack a collection to do it, but that
would screw up my pagination and wouldn't show unless I scrolled to the
bottom.

I just want a footer that displays the total of each column.  Is there any
good way to do this?  The Summary and Grouping classes were disappointing.

Once, the combo box is changed it fills a label with the value selected.

{
lblCompanyName.text = evt.currentTarget.selectedItem.projectname;
}

The problem is what if only one item exists in the combobox. There
cannot be any change. I want the label to be filled by default item in

selectedIndex but with no luck. Any suggestions is appreciated.

[flexcoders] How to make Tree only display branch nodes without filters

[Greg Hess]

Hi All,

My application has a global data model representing a file system. I
have a tree control allowing users to navigate the file system
directories. I am using a global data model so that rename, delete,
add operations automatically propogate to other UIComponents bound to
file children collections.

So I need my trees data provider to be bound to a collection with
branch and leaf nodes but only display ItemRenderers for branch nodes.
I needed a custom TreeIR and I thought I could just set its visible
and includeInLayout properties but it is not working. I think I can do
this in the TreeIR by overriding createChildren(), updateDisplayList
and measure to do nothing with a leaf node but it feels like I should
be using a custom Tree impl to actualy just ignore those leaf nodes.

I also tried to use itemToItemRenderer and return null for leafs but
they are still drawn...

Any help is much appreciated.

Subject: [flexcoders] Populate label with item from combobox

 

Hi,

I have a combobox which is populate by an XML file and works fine.

code:
mx:ComboBox creationComplete=userProjects.send()
dataProvider={userProject} labelField=projectname
change=setCompanyName(event) width=313 /mx:ComboBox

Once, the combo box is changed it fills a label with the value selected.

code:
private function setCompanyName(evt:Event):void
{
lblCompanyName.text = evt.currentTarget.selectedItem.projectname;
}

The problem is what if only one item exists in the combobox. There
cannot be any change. I want the label to be filled by default item in
the combobox and also on any chnage, I've tryed with selectedItem and
selectedIndex but with no luck. Any suggestions is appreciated.

Kind Regards,

In theory, you can override createItemRenderer and return different

Subject: [flexcoders] How to make Tree only display branch nodes without
filters

 

Hi All,

My application has a global data model representing a file system. I
have a tree control allowing users to navigate the file system
directories. I am using a global data model so that rename, delete,
add operations automatically propogate to other UIComponents bound to
file children collections.

So I need my trees data provider to be bound to a collection with
branch and leaf nodes but only display ItemRenderers for branch nodes.
I needed a custom TreeIR and I thought I could just set its visible
and includeInLayout properties but it is not working. I think I can do
this in the TreeIR by overriding createChildren(), updateDisplayList
and measure to do nothing with a leaf node but it feels like I should
be using a custom Tree impl to actualy just ignore those leaf nodes.

I also tried to use itemToItemRenderer and return null for leafs but
they are still drawn...

Any help is much appreciated.

Thanks,

Greg

 

[flexcoders] getting absolute height from component

If I have a canvas with height set to 100%, how do I get its absolute height?

RE: [flexcoders] getting absolute height from component

You're accessing the 'height' property before the LayoutManager has
determined what its height should be. You need to wait at least until
the component has dispatched an updateComplete event.

RE: [flexcoders] Inline EventListener in MXML tags - confusing description in Developers guide.

[Gordon Smith]

 Why can't i just call removeEventListener in ActionScript on the type
of event declared in MXML?

 

Because you don't know what to pass for the handler reference. When you
write MXML code like

 

Button click=a=1; b=2/

 

the MXML compiler autogenerates an event handler method whose body
containts the statements in the attribute value, and you don't have
access to this method.

Quoted from Adobe Flex Developers Guide, page 78

However, it is best practice to use the addEventListener() method.
This method gives you greater control over the event by letting
you configure the priority and capturing settings, and use event
constants.
In addition, if you use addEventListener() to add an event handler, you
can
use removeEventListener() to remove the handler when you no longer need
it. If you add an event handler inline, you cannot call
removeEventListener()
on that handler.

- End of Quote -

What i think is a little bit confusing is, that it's said that inline
EventListener can't be 
removed? Or is it just a little bit unluckily expressed? Why can't i
just call 
removeEventListener in ActionScript on the type of event declared in
MXML?

 Hello All,



 Well, I'm stuck.  I've approached this about 3 different ways and have run
 into (different) dead ends on all of them. I've tried using multiple
 datagrids, which I got working fabulously, but setting the datagrid to width
 100% does really wacky things with the column sizes.  I've also tried to use
 the built-in Summary classes with the AdvancedDataGrid, but they seem only
 to work with Grouped data. I could hack a collection to do it, but that
 would screw up my pagination and wouldn't show unless I scrolled to the
 bottom.



 I just want a footer that displays the total of each column.  Is there any
 good way to do this?  The Summary and Grouping classes were disappointing.



 Thanks

How can I attach it to two without having to instantiate two versions

A display object can only have a single parent, so you will have to have two

[flexcoders] ArrayCollection filterFunction only gets called on root item

[Greg Hess]

Hi All,

I have a tree control who's data provider is an ArrayCollection
holding a single File object I defined. The File object represents the
root of a remote file system hierarchy that has children getter that
supports the tree control and each child is rendered in the tree with
an ItemRenderer.

The tree control displays the File hierarchy well and it traverses the
data providers children as expected. However, filter does not. I
wanted to apply a filter to the data provider so only directory items
are displayed. I specified the filterFunction and refresh the
dataProvider but it only gets called on the first root node and not
the data model hierarchy and each item that gets rendered in the tree.

Should I have implemented a special interface so the tree or data
provider can properly filter the object hierarchy?

What am I doing wrong?

Any help much appreciated.

I am recommending that you modify your renderer in Actionscript instead
of MXML.  It will be much more efficient, and you can use
ListItemRenderer as a template, and borrow background modification code
from the examples on my blog for DataGridItemRenderer (which is a
TextField).

RE: [flexcoders] air sqlite image loading

[Jim Hayes]

I'm not sure why you're using Base64Encoder/Base64Decoder here, tbh (perhaps 
you really need to send over the net as text at some point?).
Unless it's because you are using only a string for the insert statement?

You can insert binary data into a blob field in the AIR database directly, 
though you probably do have to use a different syntax for the query:

try using sqlStatement parameters instead of a concatenated string : e.g

var sql:SQLStatement = new SQLStatement();

sql.sqlConnection = someSqlConnectionInstance;

var sqlInsert:String = INSERT INTO Person VALUES(:personName ,:personEmail 
,:personImageData);;

sql.text = sqlInsert;

sql.attributes[:personName] = person.name;
sql.attributes[:personEmail] = person.email;
sql.attributes[:personImageData] = person.image_As_ByteArray; // (however you 
get that).


(There are other good reasons for using sqlStatement parameters, but I'll leave 
for now).

I know you can store the image as a byteArray (perhaps encode a bitmapData with 
JPEGEncoder or PNGEncoder ?) and read that back out, I'm guessing that it would 
also take a BitmapData (though you would get no compression with that. It may 
be easier to stuff it back into an image component, however).

If storing as a byteArray of a PNG or JPEG image rather than a bitmapData (*if* 
storing a BitmapData is possible, that is) then you may need to extract the 
image from that byteArray using Loader .
(I'm unsure as to whether the Image component accepts an encoded byteArray as 
content in flex3, I know it did not in flex2)

Apologies if any of the above is incorrect, it's from memory and from about a 
year ago at that.

I'd take it all back to the very simplest test project if I were you, and just 
test the simplest thing that will/won't work before taking it further.
I found all the image storage / display stuff a bit of a struggle initially, 
that approach helped me a lot (together with reading the docs in depth!).

[flexcoders] referencing embedded images inside AdvancedDataGridGroupItemRenderer

[Brandon Krakowsky]

I've embedded some images like so:

[Embed(source=images/image1.png)]
private var image1:Class;

[Embed(source=images/image2.png)]
private var image2:Class;

I can't seem to reference these class names from a String like so:

override public function set data(value:Object):void {
img = new Image;
img.source = getDefinitionByName(value.icon) as Class; 
//getDefinitionByName is part of flash.utils package
img.width = 22;
img.height = 22;
addChild(img);
}

I also tried the following:
value.icon as Class
Class(value.icon)

[flexcoders] Understanding DataGridColumn#sortCompareFunction with composite custom classes

[florian.salihovic]

I'm currently working with a custom classes which are composites. I display the 
needed 
data via custom ItemRenderer which extends the mx.controls.Text component. It 
works 
pretty nice and is pretty flexible. But i need to sort my data as well. After 
some researches 
i learned to implement a custom sortCompareFunction. My current implementation 
works 
just like the following in a class subclassing 
mx.controls.dataGridClasses.DataGridColumn:

 /* Begin */

protected function compare(arg1:CustomClass, arg2: 
CustomClass):int {
if (!super.dataField) {
return 0;
}
return 1;
if (arg1.hasOwnProperty(super.dataField) 
arg2.hasOwnProperty(super.dataField)) {
return 
ObjectUtil.stringCompare(arg1[super.dataField].toString(),

arg2[super.dataField].toString(), true);
}
// property is a known property of the custom class
if (arg1.property.hasOwnProperty(super.dataField) 

arg2.property.hasOwnProperty(super.dataField)) {
return 
ObjectUtil.stringCompare(arg1property[super.dataField].toString(),

arg2.property[super.dataField].toString(), true);
} 
return 0;
}

/* End */

But i get the error message:
Error: Find criteria must contain at least one sort field value.

Where do i have to set it?

Any examples of sorting custom object hierachies in DataGrid controls would be 
appreciated.

Best regards!

[flexcoders] Layout challenge

[Richard Rodseth]

Here's what I need:

A single row containing a right-aligned PopUpButton and to its left,
an mx:Label that fills the remaining space. The label has
truncateToFit=true ad should display an ellipsis when necessary (the
label can have very long contents).

Ideally the PopUpButton could be of variable width based on it's label
length, but with a minimum.

Any suggestions for the best approach to this layout? Also, I'm
finding that truncateToFit doesn't seem to be working when the
mx:Label is of varying size. The case I was trying assumed a fixed
width for the PopupButton, and used left= and right= constraints
on the mx:Label.

Thanks.

[flexcoders] display code won't work outside of the mx:State and mx:AddChild

[Scott]

I'm not sure why this is not working but I can't seem to get it to work
correctly...

 

I've got the following code:

 

mx:State name=Startup

  mx:AddChild position=lastChild

mx:Image x=31 y=30 source=images/FT.gif/
(this one displays the logo correctly)

  /mx:AddChild

  mx:AddChild position=lastChild

controllers:windowedApplication top=0
left=0 right=0 bottom=0 borderColor=#E9321A
backgroundColor=#FBF5F5/

  /mx:AddChild

  mx:AddChild position=lastChild

mx:VBox width=100% height=100%
horizontalAlign=center verticalAlign=middle 

  controllers:Login

  id=loginController

  width=500 height=400

 
loginSuccessful=this.currentState='LoggedIn';  currentState=login
horizontalAlign=center/

/mx:VBox

 

  

  /mx:AddChild

/mx:State

 

I changed the login class so that it will work in all states.  So in
other words, I want to move the login controller outside of the main
state handling and always displayed.  It will show a button to log in, a
login screen, and a welcome with a logout button depending on the state
within the login controller.

 

Anyway, if I move the:

 

  controllers:Login

  id=loginController

  width=500 height=400

  loginSuccessful=this.currentState='LoggedIn';
currentState=login horizontalAlign=center/

 

 

outside of the state then it will not display.  I also tried to create a
vbox/hbox like this:

mx:Script

(singleton class)

... 

...

/mx:Script

  mx:HBox x=10   y=30

mx:Image source=images/FT.gif/  

  /mx:HBox

  mx:VBox x=100 y=100 (tried with/without location x/y)

controllers:Login

id=loginController

width=100% height=100%

 
loginSuccessful=this.currentState='mainApplication';
currentState=login horizontalAlign=center/

  

/mx:VBox

mx:States

  mx:Name=login

Etc.

 

Also, the FT.gif does not display when it's outside the mx:States area.


 

Any ideas on why this is happening?

 

Thanks!

RE: [flexcoders] Understanding DataGridColumn#sortCompareFunction with composite custom classes

[Alex Harui]

If the property identified by the column's dataField doesn't actually
exist, I think that's when you get this error.  A sortCompareFunction on
a column specifies a SortField's compare function.  You can also specify
a custom Sort with a global compareFunction that shouldn't check for the
existence of fields.  You would get the HEADER_RELEASE event, call
preventDefault() and set the collection's Sort accordingly

protected function compare(arg1:CustomClass, arg2: CustomClass):int {
if (!super.dataField) {
return 0;
}
return 1;
if (arg1.hasOwnProperty(super.dataField) 
arg2.hasOwnProperty(super.dataField)) {
return ObjectUtil.stringCompare(arg1[super.dataField].toString(),
arg2[super.dataField].toString(), true);
}
// property is a known property of the custom class
if (arg1.property.hasOwnProperty(super.dataField) 
arg2.property.hasOwnProperty(super.dataField)) {
return 
ObjectUtil.stringCompare(arg1property[super.dataField].toString(),
arg2.property[super.dataField].toString(), true);
} 
return 0;
}

/* End */

But i get the error message:
Error: Find criteria must contain at least one sort field value.

Where do i have to set it?

Any examples of sorting custom object hierachies in DataGrid controls
would be 
appreciated.

Best regards!
