Re: [flexcoders] Clean way to filter very large ArrayCollection (in pieces) using filterFunction
I guess you can easily reset some sort of counter before refreshing collection and then increment it from inside of filter function without getting into internals.

I use ArrayCollection's filterFunction to perform the filtering, but as the recordset grows, it (obviously) takes longer to filter and makes the interface less responsive. Is there a way to access/adjust the internals of filterFunction without having to roll my own or implement greenthreading? Similarly, is there a way to know how far into the filtering it is, for example to update a Number of Matched Records box that gets updated DURING the filtering process rather than jst at the end when it is done?

Re: [flexcoders] Mapping Java Generics to an AS3 Vector through BlazeDS remoting?
You won't be able to get generic element type information during runtime so what's the point? The only likely approach I guess is generic serializer/deserializer. And still I'm not sure whether vector element type information is serialized/deserialized with vector or is it just a compile time information unreachable during runtime.

3. Then clicked delete.
4. Then again click on check... (Traces [object] [object]

does that mean in each of my function I need to set all the params to

These events are thrown by event handlers on the actual individual
component (either a button or a grid).
for the grid:
private function dispatchRowClickEvent(ev:ListEvent):void{
var e:ListEvent=new ListEvent('rowClick');
e.rowIndex=ev.rowIndex;
dispatchEvent(e);

for the button
mx:Button id=btnRefreshRecord

var currentIssueForm:IssueForm = new IssueForm();
var buf:XML = XML(event.currentTarget.selectedItem);
currentIssueForm.modelIssue = buf;
PopUpManager.addPopUp(currentIssueForm, this, true);
PopUpManager.centerPopUp(currentIssueForm);
}
However at runtime it fails because event.currentTarget.selectedItem
is null.
It is null because the event I am catching is the custom component
event and not the low-level datagrid event
Is there a way to wrap the datagrid event [and keep its content]
whilst still renaming it ?
Or maybe there is just a simpler way to do this ?

Re: [flexcoders] data providers and filter functions
The simplest solution as I see it: create another collection. R. On 6/5/07, Ariel Jakobovits [EMAIL PROTECTED] wrote: I have a global variable called categories. It is an XMLListCollection populated when a user logs in, representing the categories they have created. I use the categories collection as a dataprovider in various controls. I also have a global variable called selectedItem. An item, among other attributes, has a list of assigned categories. What I am approaching is a view with two lists. One list contains the categories that have been assigned to the selected item. Easy: dataprovider = selectedItem.categories. The other list needs to contain the categories that have not been assigned to that item yet. The basis for the data is the global categories collection, but since the filterFunction is applied to the dataprovider and not the control itself, the filter function will affect all controls using the categories collection.

Re: [flexcoders] Validating custom component - how to get error to display next to field
Hi, John. My previous message wasn't any good. Sorry. :) The error box is one of components rawChilds. I guess what you need to check is UIComponents validationResultHandler() method. validationResultHandler()method public function validationResultHandler(event:ValidationResultEventhttp://livedocs.adobe.com/flex/2/langref/mx/events/ValidationResultEvent.html ):void http://livedocs.adobe.com/flex/2/langref/specialTypes.html#void Handles both the valid and invalid events from a validator assigned to this component. You typically handle the valid and invalid events dispatched by a validator by assigning event listeners to the validators. If you want to handle validation events directly in the component that is being validated, you can override this method to handle the valid and invalid events. You typically call super.validationResultHandler(event) in your override. R. On 4/26/07, Roman Protsiuk [EMAIL PROTECTED] wrote: Is Validator you use required=true? R.

You can listen for the menuShow event on the root menu object. The
event object's menu property actually points to the submenu that's
being popped up, through which you can check its position and size and
make sure it's within the screen area (move it).

Re: [flexcoders] Can someone explain this?
from documentation: 1) BitmapData.copyPixels(). (a) Bitmap as I understood is the target. It has public bitmapData which copyPixels should be called.

The above is from the help file. 1) the pixel-copying routine is referring to BitmapData.copyPixels() ? 2) What does it mean by the Bitmap object must meet certain conditions to use it ?

Howdy again.
The flex application that I'm building is really quite simple which is
good cause I'm learning flex. However that said.. in html we have onLoad()
which we put on a page. I have built a function called CostCalc() everytime
someone changes a field it will recalculate each field. I got that working
perfectly.
However, when I first load the page up with values every value in the
form is 0.00 until I make a change to a field. I know that in flex we
have creationComplete= onCreationCompl ete(event) ; but when I put in the
function call CostCalc() it doesn't seem to work. Below is the code.
Disregard the RequestType stuff. I'm switching states based on the URL.
//Alert.show( RequestType) ;
if (RequestType == 1)
{
EndValue();

Re: [flexcoders] Dispatching Event Question?
When you are adding an event listener the only thing that tells who is to dispatch the event is who's addEventListener() is called. I mean if you are calling addEventListener(...) this means that you are listening to 'this' that will dispatch the event. If a.addEventListener(...) then 'a' will dispatch it. What you need is smth like: instanceOfA.addEventListener(myEvent, myBListenerFunc); inside of the B instance. R.

Howdy again.
The flex application that I'm building is really quite simple which is
good cause I'm learning flex. However that said.. in html we have onLoad()
which we put on a page. I have built a function called CostCalc() everytime
someone changes a field it will recalculate each field. I got that working
perfectly.
However, when I first load the page up with values every value in the
form is 0.00 until I make a change to a field. I know that in flex we
have creationComplete= onCreationCompl ete(event) ; but when I put in the
function call CostCalc() it doesn't seem to work. Below is the code.
Disregard the RequestType stuff. I'm switching states based on the URL.
//Alert.show( RequestType) ;
if (RequestType == 1)
{
EndValue();
CostCalc()
}
else
{
LandedCosts( );
CostCalc()

Re: [flexcoders] Accessing Item Renderer in a List.
All the interaction with item renderer is expected to be done via data set to it. And the feedback may be for example bubbling event (though, I use this technique very seldom).

2) Connect with the first problem I think, if I set the last answer as the

For a doubleClick event to occur, it must immediately follow the following series of events: mouseDown, mouseUp, click, mouseDown, mouseUp. All of these events must share the same target as the doubleClick event. The second click, represented by the second mouseDown and mouseUp events, must occur within a specific period of time after the click event. The allowable length of this period varies by operating system and can often be configured by the user. If the target is a selectable text field, the word under the pointer is selected as the default behavior. If the target InteractiveObject does not have its doubleClickEnabled flag set to true it receives two click events. R.

Re: [flexcoders] Quick Question
As far as I remember someone once told me... :)
When you write:
mx:Button x=23 y=242 label=Button click={myFunction()} /
or
mx:Button x=23 y=242 label=Button click={foo = bar;} /
the event handler (function) is generated dynamically.
So writing
mx:Button x=23 y=242 label=Button click={myFunction()} /
means that some method will be generated by compiler and it will call
myFunction().
If you don't use braces myFunction used for handling event and no additional
function is generated.
Am I right?

This is just calling myFynction() in response to the button click.
Second:

Here, you have the same as above, but you are (for some reason) trying to
wrap the function call in a binding which is having no effect in this
context, so the effect is the same.
Perhaps some research on Flex binding will help.

string? How to implement the following function?
function getObjectPropertyValue(obj:Object, property:String)
{
return ?
}
This function should return obj.property_name, if property =
property_name.
Thanks.

Re: [flexcoders] mouseOver an element within a TileList problem
I don't really see problem in this. You just have to add event handler to
handle itemRollOver event of your TileList. That's all. Handler may look
like:
protected function onItemRollOver(event : ListEvent) : void {
someLabelUnderTheList.text = event.itemRenderer.data.name;
}
Or something like this. Here event.itemRenderer is list element you rolled
over and event.itemRenderer.data is this elements data (from data provider).

I have a TileList populated with data (ArrayCollection). Underneath the

data (for example
name, category) to appear in the blank area. This sounds rather straight
forward but I having
a bit of a hard time getting it to work.
Is there a way to explicitly reference the currently mouseOver'd object
so it can be displayed
outside the TileList. item renderers and repeaters don't seem to help much

[flexcoders] Opening GIF in Safari (offtopic?)
Hi, everyone. Dunno maybe it's offtopic. However, the question is: if I try opening GIF image in a Safari browser via ExternalInterface, e.g. ExternalInterface.call(window.open, /content/some.gif, _blank); I get it saved instead of showed. Browser just saves image and that's all. I'm not keen on Safari and stuff. Maybe someone knows what it's all about. Thanks, R.

Re: [flexcoders] Re: TitleWindow missing all focus events??
As the matter of fact I just forgot to say that for focusInHandler to work
your component has to implement IFocusManagerComponent. In this way you
don't have to add these methods as event listeners manually.
And as to relatedObject part of understanding came from documentation and
another one came from reading sdk sources.

Thanks, Roman. Actually you answered my another question: I have been
trying to figure out why I cannot focus in the edit control inside the

I am still a little puzzled by how focusIn works. I realized I have to
do these two lines before the focusIn/OutHandler gets invoked:
this.addEventListener(FocusEvent.FOCUS_IN, focusInHandler);
this.addEventListener(FocusEvent.FOCUS_OUT, focusOutHandler);
Does it mean by default, TitleWindow doesn't get FOCUS events
dispatched to?
Thanks again for your great help!

So the reason for this is because PopUpManager listens for the SHOW and
HIDE events (see PopUpManagerImpl.as line 471). If your popped up
component dispatches SHOW or HIDE then the PopUpManager takes this to mean
that it should show or hide the popup.
So when your popped up window dispatches SHOW, PopUpManager calls
showModalWindow(), which then also sets the window's visible property. If
this setting of the visible property in turn triggered the SHOW event, then
we'd get caught in an endless loop of PopUpManager calling showModalWindow()
over and over again.
So this isn't a solution, but hopefully it helps to understand what's
going on.

The problem here consist in show event which should be dispatched when
component visibility is changed to true as I understand.
The bad thing is this pop up dispatches show event ONLY while it is
NOT MODAL. If I say 'let's make it modal', show event isn't
dispatched. Confusing. At least as for me.
Can anybody explain this behavior? Or say it's not right?

[flexcoders] SOLVED: IFocusManagerComponent and removePopUp
Thanks for the huge amount of advises. ;)
As it appeared the hole thing was in method hidePopUp of PopUpWindow.
We do removePopUp there and after it focus of course changes and this
pop-up fires focusOut. in focusOutHandler we call the very same
hidePopUp. But, it isn't popped up now. So the only thing missing in
hidePopUp is test for isPopUp. The final code for hidePopUp is
following:
public function hidePopUp() : void {
if (isPopUp) {
PopUpManager.removePopUp(this);
}
}
That's all.

The only thought i have: it's because focus is lost (it stays in
pop-up) when pop-up is removed and the lost focus is unacceptable for
flash player. So I added clickButton.setFocus() on close. But if i do
it before removePopUp then PopUpWindws focusOutHandler removes it. Why
do i need to call it manually anyway

Re: [flexcoders] Re: Code behind- do you use it?
Hi, everybody. Interesting thing that just recently we had discussion at our team about code-behind and why should we use it or use not. The point we are at the moment is: we've used code-behind more like legacy related thing from Flex 1.5 (FlexBuilder) and now we've got a lot of classes which simply copy several properties. Definitely it's not very object-oriented. And now the idea is NOT to use code-behind where possible. The discussion continues so it's very interesting to hear different opinion.

Re: [flexcoders] It shouldn't be this hard.
The first thought is:
mx:Canvas width=100% height=100%
mx:Image source={yourSource} horizontalCenter=0 verticalCenter=0
/
/mx:Canvas
To scale, dunno, but maybe something like:
mx:Canvas id=imageContainer width=100% height=100%
mx:Image id=image
source={yourSource}
width={imageContainer.width image.width ? imageContainer.width :
image.width}
height={imageContainer.height image.height ?
imageContainer.height : image.height}
scaleContent=true
horizontalCenter=0
verticalCenter=0 /
/mx:Canvas
This one probably won't work, it's very dirty, however might give you a
clue... ;)
And the easiest way to scale, but still, not so nice from the point of ui
(it scales both way) is just:
mx:Image source={yourSource} scaleContent=true width=100%
height=100% /
Have fun,

I hate the flex documentation...
All I want to do is dynamically center an image on my stage.
I have a VDividedBox with an image in the top, and text in the bottom.
I loading in images by setting the source of an image tag(probably not
the best way to do it, but again I hate the Flex docs...).
So when the image loads I am trying to set it to center in the upper
pane of the vdividedbox, but all my attemps have failed.
It would be nice to also resize the image as the divideBar is dragged,
but only to the original size of the image, then it just centers.
Thanks

Re: [flexcoders] Is this a bug about FocusEvents and popupmanager?
It is more likely Firefox bug. Are you using this browser? Because the
described behavior is reproducible in Firefox but not in IE. Try to search
older posts in list seems to me that I saw this problem being discussed
here.

Hi to all,
I have a couple of textinputs that all have focusIn and focusOut

One of these tese inputs open a file reference (FileReference.browse)
When you press cancel in file explorer dialog, it closes silently. But
when i click another textinput, two focusIn events are disparchet together,
one for the old textinput one for the recently clicked textinput.
Below is a code to demonstrate the issue.
Just click 1st textinput, than 3rd one. Close the dialog with cancel
button, than click the first textinput.
log variable was expected to be:

However it is:

[flexcoders] IFocusManagerComponent and removePopUp
Hi, everyone.
As I understand in order to properly handle focusOut event for my
component it should implement IFocusManagerComponent. The component I
develop is a pop-up window. Then strange and very unpleasant bug
appear. After I set focus to one of my components child and after I
click a button on it to close it browser crashes (firefox, ie).
I don't know what to say more. Here's example. Simply clicking close
me crashes browser. Totally confused.

The only thought i have: it's because focus is lost (it stays in
pop-up) when pop-up is removed and the lost focus is unacceptable for
flash player. So I added clickButton.setFocus() on close. But if i do
it before removePopUp then PopUpWindws focusOutHandler removes it. Why
do i need to call it manually anyway? :/ And if i do it after calling
removePopUp then situation remains the same, browser crashes, not
surprisingly.
Any help highly appreciated.

Re: [flexcoders] IFocusManagerComponent and removePopUp
Yeah, and this bug appeared just recently. Is it related with Flash
Player 9.0.28 changes or with FlexBuilder 2.0.1 hard to tell.
Everything worked as it is without crashes before.

Re: [flexcoders] Filter An ArrayCollection By Multiple ArrayCollections (selectedItems)
Hard to understand what exactly do you need. However if I understood

I'm trying to think of the best way to approach this.
I have 3 main arrayCollections - store, store_category and 6 X
categories (categories filtered into groupings).
A user would select several items from the cats AC's that would
filter store_cats AC (the mappings). Then the stores with matches
are filtered from the stores AC.
I have a filter function in place but can only figure out out to
feed it one value - not an array of selected values from several
DataGrids.
public function addMapping():void
{
ac.addItem({dg1:selectedItem.text});
}

Re: [flexcoders] Capturing an event everytime an item becomes visibile in a viewstate

Re: [flexcoders] New to Flex - dynamic text in mx:Label?
Hi, Alex.
Tried your example. It works. %)
However, maybe what you need is something like this:
[Bindable]
protected function get someText() : String {
return _someText;
}
protected function set someText(value : String) : void {
_someText = statusToImage(value);
}
private var _someText : String;
and:
mx:Label text={someText} /
This seems pretty flexible to me.

Hi there,
Given this function:

How precisely can I set it as text-generator for a label? I've tried:
mx:Label text={statusToImage('abc')} /
And Flex Builder writes: 1180: Call to a possibly undefined method
statusToImage..
Seems it's right above in the same mxml file though!
Thanks in advance.

Re: [flexcoders] Multiple dynamic filterFunction help
