[flexcoders] Use ChangeWatcher with dynamic Object?

[Tracy Spratt]

I want to have a dynamic Object to which I can add properties at will,
making an associative array or hashtable, and Object works fine for this.

 

However, I also want to be able to set up changeWatchers for certain
properties, but my watchers are never getting fired.  I know Object is not
bindable, but should an explicit ChangeWatcher fire when a dynamic property
is  added or changed?

RE: [flexcoders] Text stuck on screen BUG in FP10 or IE7????

[Alex Harui]

Doesn't sound familiar.  I'm not sure how you're moving the main sprite and 
whether the text is within the stage or not.  Trace getTImer() on enterFrame to 
see how fast the player is refreshing the screen.

So I have an app that has upto 300 sprites on screen at once and inside each 
sprite is a textfield with embedded font (all Arial font).

In IE7, when you move the main Sprite around the sprite/textfield text gets 
stuck on the screen then eventually disappears. Its like the browser isn't 
refreshing fast or something. The amount of time it takes for the 
sprite/textfields to all go away varies sometimes 5 seconds sometimes 30 
seconds.

Wondering if its because of the way FP10 handles text now or ???

Here is the codes:
 
  override protected function updateDisplayList(unscaledWidth:Number, 
unscaledHeight:Number):void{
super.updateDisplayList(unscaledWidth, unscaledHeight); 
lal.setActualSize(unscaledWidth, unscaledHeight);
  }
  
  override protected function createChildren():void{
super.createChildren();
   
if( lal == null ){
  lal = new Label;
  lal.text = "Label";
  addChild(lal);
}
  }
  
  override protected function measure():void{
super.measure();
measuredWidth = lal.getExplicitOrMeasuredWidth();
measuredHeight = lal.getExplicitOrMeasuredHeight();
  }
 
I track the processing of these functions. The red code excuted before the 
green code. I thought the children actual size should be set before his 
parent container and then use the children's proterties to set his parent 
container.
I comment the green code.So There is nothing on the screen. 
The value of "lal.getExplicitOrMeasuredWidth/Height();" is as same as the 
"unscaledWidth/Height"
Flex already know before setting the Label's width and height. 
Why should the label be set up again ?

I forgot to say how to do the measurement. Here's how I'd do it:

function measure():void
{
measuredWidth = lal.getExplicitOrMeasuredWidth();
measuredHeight = lal.getExplicitOrMeasuredHeight();

[flexcoders] Filter Does Not Work on a Column when Record Count is more than 4000

[Angelo Anolin]

Hi FlexCoders,
I have this very strange bug which I don't have any idea why it is happening.

Basically, I have a datagrid which I am populating with an ArrayCollection 
data.  The array collection is being populated through via XML which I am 
retrieving from a web service.

When the record reaches more than 4000 records, the search functionality I 
implemented in my datagrid does not seem to fire up anymore.

Here are snippets of my codes:

private function searchFilterGrid(e:Event) :void
{
 e.stopImmediatePropagation()
 if(txtSearch.text == '')
 {
  arrDP.filterFunction = null;
 }
 else
 {
  arrDP.filterFunction = textFilter;
 }
 
 arrDP.refresh();
}
private function textFilter(item:Object) :Boolean
{
 switch(cmbColumns.text)
 {
  case "Booking Code":
   return item.BK_CODE.toLowerCase().indexOf(txtSearch.text.toLowerCase()) != 
-1;
  case "Booking Code Description":
   return item.BK_CODE_DESC.toLowerCase().indexOf(txtSearch.text.toLowerCase()) 
!= -1;
  default:
   return false;
 }
}

I invoke the searchFilterGrid function on the change event of the textInput 
control:



If I searched the Booking Code, even if the record is more than 4000, I am able 
to display the result. But when I try to search the Booking Code Description, 
when the record count is more than 4000, search and filter functionality does 
not fire up.

Any ideas/advice?  Thanks.

[flexcoders] How to get rid of annoying chart trial message

[iloveyouwisconsin]

I have flex 3 professional. On 2 of my projects when I create a chart the 
charts come out fine. However, on my 3rd project I get the annoying "chart 
trial" message on the chart. How do I get rid of it? The only thing I can think 
that I've done differently is the location of the project is saved on my 
desktop while the other 2 projects are saved in my documents folder. I've tried 
to create a new project and move the 3rd project to this but still get the 
chart trial message. 

(Looking at Adobe's website there is a way to convert a FB2 version w/out chart 
license to FB2 w/ license by simply copying the license key. I've built all my 
projects in FB3 so that shouldn't apply, I don't think)

What am I missing?

You are correct! You should call the alert box after instantiating the class & 
passing in the value & not in the constructor.

As for datagrid column names, you could access the datagrid(& therefore its 
columns) by calling Filtermanager.datagrid.dataField if you wanted.
Don't know if that helps or is exactly what you were looking for :)

[flexcoders] What to use instead of Model component in Flex 4?

[ben gomez farrell]

Hey guys,
Just starting to build my first Flex 4 app.  I'm making an MenuBar as 
the first thing I'm attempting.  I can get it working with XML data if I do


   



However, I'd like to break out the XML data into a separate 
file/component.  Normally I'm not so organized - so I don't really think 
I ever did this in Flex 3, but I understand you can just create a Model 
container, and you're good.

It doesn't look like I can do this in Flex 4.  I'm trying different 
things with the DataGroup container  - putting a dataprovider in it, or 
a XMLList in it, but nothing seems to work out.

Does anybody know the proper way to do this?
thanks!

[flexcoders] How to avoid recursive FABridge calls?

[Paul Wideman]

So I'm running into the problem where you cannot make recursive FAB>JS>FAB 
calls, an exception is thrown by the FAB. Here's an example:

[ActionScript code]
public function myFirstMethod(myCallback:Function)
{
  doSomething();
  myCallback();
}

public function mySecondMethod()
{
  doSomethingElse();
}

[Javascript code]
function start()
{
  myFabObject.myFirstMethod(myOtherJavascriptFunction);
}

function myOtherJavascriptFunction()
{
  myFabObject.mySecondMethod(); // this line fails
}

The only workaround I've found for this is to queue the javascript callback up 
on another thread (or whatever Flash has) with setTimeout, like so:

public function myFirstMethod(myCallback:Function)
{
  doSomething();
  flash.utils.setTimeout(myCallback, 1, myArgs);
}

This allows myFirstMethod to complete without directly calling back into 
javascript, so it breaks the chain of recursion. But it's obviously ugly & 
kludgey, so I was hoping someone out there had a better solution. Any ideas?

[flexcoders] CuePointEvent missing optional parameters

[kris range]

I'm using the VideoDisplay class and listening for cue points. I can

I need to access it a different way?

Do you need to use setActualSize on the label before you measure it?

[flexcoders] Re: Custom Actionscript component data-binding question

[Keith Hughitt]

I'm testing the variable during the FilterManager constructor. I
actually don't have Flex Builder, so I've been using Alert and
ObjectUtil to output information about the variables at run-time, e.g.:

 public function FilterManager():void {
 super();
 Alert.show(test);
 this.initDataGrid(dataSource);
 this.initFilters();
 }

When I try to print out the contents of either "test" or "_test" using
Alert, a blank box pops up. I *am* able to see the contents set from
MXML during the setter:

 [Bindable]
 public function set test(value:String):void
 {
 _test = value;
 Alert.show(_test);
 }

So perhaps the constructor is simply called before the variable has been
set?

Also, I am trying out your suggestion of passing in the ArrayCollection
instead of the DataGrid itself. One of my initial reasons for using the
DataGrid was so that I could have access to the column names that had
been chosen. Perhaps what I'll do is pass in a list of columns names
along with the data.

Does this look about right though?

  public class FilterManager extends Form {

 [Bindable]
 public var dataSource:ArrayCollection;

 private var _datagrid:DataGrid;

 public function FilterManager():void {
 super();
 this.initDataGrid(dataSource);
 this.initFilters();
 }

 private function initDataGrid(d:ArrayCollection):void {
 _datagrid = new DataGrid();
 _datagrid.dataProvider = d;
 }
...



...where "dataArray" is the relevant ArrayCollection.

Thanks!
Keith

[flexcoders] ADG/DataGrid cell change performance on large data set

[tntomek]

When I edit a cell and press Tab to move horizontally to the next cell in the 
same row the grid behaves wonderfully. If however, I make my next selection to 
another row this becomes incredibly slow (10-15 seconds). Is there any reason 
for this slowdown? I'm using a ArrayCollection of typed objects as my main data 
source. The source is between 100-5000k rows. Surely it doesn't take Flex this 
long to switch rows. Is there anything I'm missing?

[flexcoders] Re: Performance Question

[Tim Hoff]

Using the 80-20 rule, loading all of the individuals up-front would be
the way to go (even 1000 records is reasonable).  It's going to much
better handling the search on the client with a filter; instead of
making a call for each key-stroke.  If the user types fast, it can get
very expensive.  You might also want to delay the search a half-second
or so; incase the user types additional characters.

Re: [flexcoders] Performance Question

[Kevin F. Benz]

Well, you have to avoid over the wire activity as it will cause a traffic
pattern called a ³galloping herd². Basically servlet latency causing
latency, causing And so forth. Your keyboard buffer will end up getting
ahead of the over the wire call and end up with enough spooled key events to
make it seem like your app has died.

The startup load is ³OK² but you have to deal with the impact of having the
client-side data getting stale compared to the server. Perhaps limit the
download to some number of characters allowing for the round-trip to occur
after the user has typed in enough characters.

Remember, although the numbers you present seem low, you have to plan for a
much larger sample, one where the numbers of users substantially escalate or
you wish to repurpose the algorithm in a more data-centric operation.

[flexcoders] FormItem format/validation

[markgoldin_2000]

Here is my field definition:


   

What I am trying to do is to set a flag if data has been changed and also 
format an e-mail when a user is leaving the field. 

public function formatEmails(Name:Object, bindObj:Object=null):Boolean 
{
if (validations(Name, "email") && bindObj != null)
{
Name.text = toTitleCase(Name.text);
bindObj.dataProvider[bindObj.selectedIndex][Name.id] = 
Name.text;
return true;
}  
else
{
return false;
}   
}
This code works, at most part. If I leave the field to anywhere but DataGrid 
(salesreps) then salesreps gets its email column updated correctly, but if I 
leave the email field b clicking on a row in the DataGrid then the clicked row 
gets the email value. It's my problem is clear is there a solution?

Seeing as this could and would cause problems with the application if I hit the 
back end with an AMF call every key up, I was considering loading all of their 
individuals at startup.

The majority of our users will have relatively small number of individuals (50 
to 100 or so).  Some will have a lot (500 to 1000) and VERY FEW will have more 
than that.

Which path would be better, searching and filtering by making an AMF call which 
would make a subsequent database call and roundtrip the information back to me, 
or take the initial hit to load them all at startup?

Thanks!

[flexcoders] Slider dataTip- is it possibole to have this visibale all the time

[jossminker]

I woudl like to have the datatip for my slider visible at all times, not just 
when the user is holding down the thumb. 

if this is not possible, then I would at least like the datatip to appear if 
the user moves the thumb using the arrow keys or by clicking on the track as 
the way it is at present means it will never be visible to user who are not 
using the mouse.

does anyone know of a simple way of doing this? From what I have read about 
Slider datatip there is some kind of problem with teh way it is added to the 
display that amkes it hard to customise.

TIA

In the "Navigator" pane there is an icon with arrows going left and right.
It's called "Link with Editor".  I think that's what you want.

What option is it that, when you close a file, causes the Navigator to

[flexcoders] DataGrid's variableRowHeight

[al-al :D]

Hello!

Does anyone know how to set variableRowHeight depending on the data result in 
the DataGrid? I have a TextInput and a DataGrid that is able to display search 
results. The search results may vary in lines of text, meaning one row might 
have 2 or more lines of text.

variableRowHeight works fine, but I encounter a problem when I retrieve search 
results and the last record I retrieve has multiple lines of text. What happens 
is that the following empty lines of DataGrid (say, search results are only 3, 
and current view of DataGrid can view up to 20 records), all of them follow the 
multiple line row height of the last record retrieved.

I would like to avoid this. Thanks again!

Wondering if anyone knows of a tut or component or ??? that I can use to learn

I am assuming its would be implemented by taking a bitmap snapshot of whats on

[flexcoders] Flex and IText text warping issue

[Shyam]

Hi coders,

Both Flex and Itext have text wrapping mechanism exposed via APIs. But they 
both behave differently! meaning flex might display a text (in a Text Area) 
wrapped in 4 lines while Itext might do the wrapping in 3 for the same area 
(width x height)  Flex does a lot of padding and aligning behind the scene 
while ITex api is pretty low level and requires the developer to set each and 
every value. 

I have looked at the TextLineMatrix class which provides some info on how a 
Text is aligned inside a TextArea and all, but how the actual wrapping works is 
not documented

Can anybody help me demystify it ?


BTW: Itext is a java library used to generate PDF files. For the sake of this 
post ,consider Itext as another API which has a Text Wrapping functionality.

Regards
Shyam

I forgot to say how to do the measurement. Here's how I'd do it:

  function measure():void
  {
measuredWidth = lal.getExplicitOrMeasuredWidth();
measuredHeight = lal.getExplicitOrMeasuredHeight();
  }

You don't have to write a constructor if all you're going to do it
call the superclass constructor. Just so you know. You can still do it
if you consider it a good practice.

Normally a component should not set its own
explicitWidth/explicitHeight. These properties are to be set by the
Flex framework. A component should only calculate its measuredWidth
and measuredHeight, based on its contents. The right place to do that
is the measure() implementation.

>   override protected function measure():void{
>    this.explicitMinWidth = this.explicitMinHeight = 50;
>   }
>  }

Here you should set the meauredWidth, measuredHeight, and optionally
measuredMinWidth and measuredMinHeight (they can be set to the same as
measuredWidth and measuredHeight respectively).

Okay, you haven't implemented updateDisplayList(). That's where you
have do the layout. For example, in the following way:

  function updateDisplayList(unscaledWidth:Number,
  unscaledHeight:Number):void
  {
super.updateDisplayList(unscaledWidth, unscaledHeight);

lal.setActualSize(unscaledWidth, unscaledHeight);
  }

Basically your component object is first measured by the framework,
and then it is assigned a size. You have to lay out the contents of
the component based on the allocated size (unscaledWidth and
unscaledHeight).

It is also a good idea to always call the superclass's
createChildren() method at the end of your implementation.

Re: [flexcoders] About how to implement UIComponent

[Jeffry Houser]

Step through the code.

Will the labels height and width have any values at the time 
createChildren runs?

Additionally you may need to set the width and height of 'this'.
Additionally, isn't the measure method supposed o set the measuredWidth 
and measuredHeight values of your component? In the sample you specify 
it does not.

As long as you have a reference to the

Re: [flexcoders] Re: FilterFunction creating duplicate items in the list

[Rohit Sharma]

   Hi All,

 I think I am able to solve the problem.
   The issue was that at every updates I was modifying the dataprovider
which was cast as array collection.
   Once filter is applied the arraycollection keeps only the filtered rooms.
So, even though a room might be
   present in the unfiltered source array, it will get added to the
dataprovider if it was not present in the filtered
   dataprovider.
To remove this, I have changed my update code to change the
underlying array rather than modifying
   the arraycollection.

   Thanks,
Rohit
