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

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

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

just like the following in a class subclassing 
mx.controls.dataGridClasses.DataGridColumn:

}
return 1;
if (arg1.hasOwnProperty(super.dataField) &&

arg2[super.dataField].toString(), true);
}
//  is a known property of the custom class
if (arg1..hasOwnProperty(super.dataField) &&
arg2..hasOwnProperty(super.dataField)) {
return 
ObjectUtil.stringCompare(arg1[super.dataField].toString(),
arg2.[super.dataField].toString(), true);
} 
return 0;

/* End */

But i get the error message:

Where do i have to set it?

[flexcoders] runtime localization

[Parag Metha]

Hi All,

 

I am working on runtime localization. I am using Flex 3 and LCDS 2.5.

 

I have few resource bundles specific to application along with some resource
bundles in Flex SDK and LCDS.

 

When compile all resource bundles (specific to my app, Flex, LCDS) into a
single swf/swc, the application is works properly even in runtime it is able
to find all resource bundles.

 

But, When compile only application specific resource bundles into a swf/swc
and keeping Flex and LCDS locale related swc on server and try to run the
application it is giving error;

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

I changed the login class so that it will work in all states.  So in

within the login controller.

 

Anyway, if I move the:

 

  

 

 

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

...

Etc.

 

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

[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.

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!).

RE: [flexcoders] Re: TextArea - changing backgroundColor on MouseOver when used in an ItemRenderer

[Alex Harui]

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).

It's not clear to me what exactly I would need to modify in

[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.

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

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

 



 

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?

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,

following which should help you out:

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.

[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.

Thanks,

Greg

[flexcoders] Populate label with item from combobox

[Cathal]

Hi,

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

code:
 

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,

[flexcoders] annotations on flex charts?

I am using chart annotations like the following example:

chart's dataRegion.

Does anybody know how to modify this? I tried moving the 
_annotationElementHolder.y up a few pixels but then it doesn't cover 
all the way down to the axis, and changing the height value does 
nothing.  Any suggestions?

Re: [flexcoders] Filter an ArrayCollection into an ItemRender

[Scott Bachman]

The syntax you tried is e4x (ECMAscript for XML) and only works with XML
data. For an ArrayCollection you could use a filterFunction to filter the
data. Check out, for instance,
http://www.boyzoid.com/blog/index.cfm/2006/10/19/Filtering-Data-in-Flex
or the filterFunction property of ArrayCollection in the Flex documentation.

Bingo, thanks that I believe was exactly what I needed, it would seem
that when I'm making the database tables, it would be best to use REAL

With regard  to Troy's comment on "making it *impossible* to create

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.

RE: [flexcoders] Re: PopUpManager

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: Drag and drop. From an image to a box

[Fernando Wermus]

I solved it doing this,

backgroundColor="#FF" backgroundAlpha="0"

in the box.

It is not nice! But works. Why is this behavior?

[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.

[flexcoders] Blank Images

[archtechcomputers]

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  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
effect I get a 2 second image, 3 second blank.

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?

Thanks

Joe

[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.

Re: [flexcoders] Re: Anyone have a good resource on 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.");
  }
}

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.

[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?

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

I think you can find the answers here :

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

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:

[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,

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

[zwetank]

Hi,

here I got a way to do it here
http://code.google.com/p/maashaack/wiki/Singleton

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)

cheers,

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] 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










var c:Number = 488.8;

[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,
Kuldeep Atil

[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 Vector

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

OBJECT_C extends Vector

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] 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?
