[flexcoders] Drop Down List Scroll Bar not working in DataGrid
Here is my code, every time I click on the drop down list scroll bars it closes
rather than scrolls. I've not had any answers to this problem. So if you can
figure it out their is a heap of kudos for you.
Good luck!

[flexcoders] Nested ItemRenderers Problem
I have placed a Label renderer inside of a Drop Down List inside of a Data Grid and I am having trouble makeing the Drop Down List scroll properly. I have included a link to the application which has the attached source code available if you need to look. When I click to drag the list closes for some reason. http://sbrown.myip.org/files/NestedRenders/NestedRenderers.html - Stephen
[flexcoders] Re: Nested ItemRenderers Problem
If I make the DataGrid editable I can select from the drop down and it updates the Data Grid which I can show by scrolling the Drop Down List off the panel and back on and it is still changed at the same time the Drop Down List scroll bars just close the drop down list when you click on them. If I make the Data Grid Un-editable the scroll bars begin to work but the editorDataField does not pass the update into the Data Grid and so it won't remember the changes. editable=true Scrolling fails, Update works editable=false Scrolling works, Update fails - Help!!
[flexcoders] Custom spark List drag indicators using dynamic MovieClips
Does anyone have a Flex 4.1 example of custom spark List component drag indicator that utilizes dynamically set runtime MovieClips? I've been trying to do this using the suggested customization routes from the Using Flex 4 documentation, and failing horribly. Here are the logical steps I've gone through, along with what works and what does not: ) Customize List component, with a style using a custom itemRenderer. Drag data is set to copy, not move (drag and drop items into other components). The itemRenderer contains an Image with the source dynamically set at runtime to loaded swf MovieClip content. WORKS ) Add a dragging state to the ItemRenderer that includes the Image. FAILS (Image does not display in the drag indicator although it displays fine in the normal itemRenderer states in their List positions) ) Create a custom List style that uses a custom dragIndicatorClass. WORKS … except: ) Try to dynamically set the source of the Image in the dragIndicatorClass. Perform this by trying to grab the Image source setting from the DragSource of the owner. This fails because the DragSource is null at the time the dragindicator is created. OK then, let's try to attach a listener to the owner for drag events, or listen to drag events directly. Hrm, none of this works. FAILS This was doable in mx / Flex 3 by overriding the ListBase dragImage, but this isn't the route to go with spark. Any suggestions?

[flexcoders] Data Management
If I create two tables and wish to display attributes from both and I join these tables together and display the results everything is fine. If I then need to change some of this data by updating or deleting from one of the tables (as update and delete wont work for the joined tables) I get a conflict error... Local item has changes to properties that conflict with remote change. instructing that my local joined table (that I read in from the database) is now diffrent from the current state of the table (on the server). This Data Management is getting to be a pain, does anybody know how to get around this proble or simply turn it off. I was hoping maybe their was a way to tell Zend to drop all refrences to the joined table so that their wouldn't be any more errors when the data is re-displayed. - Stephen

You'll need to look through the ArrayCollection and get either the index or

You can find the doc un using it here: http://help.adobe.com/en_US/Flex/4.0/UsingSDK/WSd0ded3821e0d52fe1e63e3d11c2f44bb7b-7fe7.html Stephen From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of Amy Sent: Thursday, November 19, 2009 4:05 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] ASDoc MXML When you give a component defined in MXML an ID, you essentially make it a public property of your component, so I want to document all of these properties.

[flexcoders] Flash-created Flex skin: Container content is offset
I'm having extreme difficulty creating a Flex 3 container skin in Flash that behaves properly. The resulting container content appears misplaced and shifted, compared to the built-in component skin that behaves normally. Setup: OS: Mac OS X 10.5.6 Applications: Flash 10.0.0.544 Flex Component Kit 1.1.2 Flex Skinning Templates 1.0.0 Flex Builder 3.0.2 Flex SDK 3.2 Steps to reproduce: I'm following the basic steps from the Importing Skins into Flex Builder document ( http://www.adobe.com/cfusion/entitlement/index.cfm?e=flex%5Fskins ). In Flash, create a new Flex skin Template (New Flex SkinsTemplatesflex_skins). Publish the document, creating a swc file with the default halo visual appearance. In Flex Builder, create a new Flex project. Import the skin (Import Skin Artwork). Drag a Panel component onto the stage. Drag a TextArea component into the Panel. Set the TextArea instance attributes to x=0, y=0, width=100%, height=100%. Problem: The TextArea now fills up the entire container component and is not restricted to the content area. Comments: This appears to be a bug with the Flex Skin Design Extensions Flex Component Kit for Flash CS3 package ( http://www.adobe.com/cfusion/entitlement/index.cfm?e=flex%5Fskins ). The content area in the template is not respected, even though no changes were made to the template! I've tried performing these steps in Flash CS3 (Flash 9) instead, and many varied approaches (introducing a mask, setting border regions, etc.), but the same results occur.

I just looked at the source, and I'm sorry to say that the algorithm for calculating the width of the text object is fixed and cannot be overridden. The width is calculated based on the length of the title text and the width of the buttons (both factors). Any width you set on the Alert object has no effect on the width of the text inside it. Your options are to either chop up the text programmatically into multiple lines, so it appears to be wrapped, or patch the framework's AlertForm component to respect the width assigned to it.

The error is related to an embedded font name not being correctly identified by flex in the system fonts list. However, on a whim, I decided to copy the code to Flex Builder and compile it there. To my surprise, it worked, and it found the proper font using the same system name I had given (PMingLiU). I suspected my problem may be a locale one, and that my system cannot correctly identify the font name because of locale considerations. I've tried setting the locale of the compile code to en_US, to no avail. So I would like to ask if anyone here knows the exact command string that Flex tells Mxmlc whenever it compiles a project. My answer might lie there.
[flexcoders] DataGrid - how to show the editor for a particular cell?
Hi, Say I have a datagrid with editable cells. That is, the user can click the cell to make the itemEditor appear and input data. This datagrid also has a feature that if I click on an empty row, I add a new record to the dataProvider and the user can input a new record. I've implemented that click-to-create-a-new-record part; now I want to do something like, when I click to create a new record, I would immediately set focus to the editor of a particular column. I'm not sure how to do this - is it possible to programatically show the editor for a specific column in a specific row? Without this change, currently the user has to click twice - once to create the new record, then second time to edit the field. Is it possible? Or any other approach you guys can suggest? Thanks! Roy

The best performance, especially in a multi-renderer DataGrid, will be if
you manually convert the XML node data ino an ArrayCollection of strongly

The mx:Model tag converts everything to a flat object. So the minute you

It's still easy enough to loop through though.

Looking at it further I've found how to get selectedItem set correctly using
the following code:

this.recordSetVO.requestVO.cursorOffset =
this.recordSetVO.requestVO.pageSize * this.pageMenu_cb.selectedIndex;
this.raiseRequestEvent(); // fetch next page of data

pageMenu_cb.selectedIndex = this.recordSetVO.currentPage - 1;

get called. Previously I could use my combobox to jump to a specific page of
results from the server, but after putting in the valueCommit code nothing
happens. : (
Has anyone experienced problems with using both valueCommit and change event

[flexcoders] Automatically granting local trust in Flex Builder 3
I thought Flex Builder 3 was supposed to automatically grant local trust to all swfs when debugging. That's what I'm trying to do, but I'm finding that all swfs are by default set to the local-with-network sandbox. System Setup: Mac OS X 10.5.4 Flex Builder 3 Safari 3.1.2 with Flash Player 9.0.124 debug Project/Local info: ) FB debugging is set to use an html wrapper as target. ) There are no use-network compile options in place in this project. ) The flexbuilder.cfg file shows that the output swf in question was added to the local trust ( ~/Library/Preferences/Macromedia/Flash Player/#Security/FlashPlayerTrust/flexbuilder.cfg ). Apparently Flash Player is not respecting this preference. I've manually targeted my project bin folder to add to the local trusted sandbox by using the Global Security Settings panel as a workaround, and checking flash.system.Security.sandboxType indicates that the sandbox has indeed changed from localWithNetwork to localTrusted. This is a pain of a workaround though. Understanding the Flash security model is a painful enough exercise (and I don't claim to be in shape on this issue), compounded with the scattered controls afforded to developers. Any enlightenment appreciated. Steve

A few things:
You'll need to override measure(), like so:
protected override function measure() : void {
measuredWidth = _txt.measuredWidth;
measuredHeight = _txt.measuredHeight;
}
and updateDisplayList(), like so:
protected override function updateDisplayList(w:Number, h:Number) : void

_txt.move(0,0);
_txt.setActualSize(Math.min(_txt.measuredWidth, w),
Math.min(_txt.measuredHeight, h));

RE: [flexcoders] Quick Start - Newbie help with Flex
Hi, The Flex Dev Center - http://www.adobe.com/devnet/flex/ - contains a Getting Started tab that links to the Getting Started Guide, an online site with overviews and examples, and also links to around 40 small quick start examples showing how to perform common Flex tasks.

In the past, I would try to get Flash to do everything that Flex can do now, with less work and effort. Anyway, I am using self-paced methods to learn Flex CS3 and be able to use it in my work with my clients/customers. I have the text: Flex Builder CS3 Training from the Source, which is a great text. I also use the training videos on Lynda.com for learning Flex. I'd like to see if there are some quick start texts or information on the web that someone knows about. While it won't replace learning and putting time into doing a lot of Flex Development, there are some tools and applications that I see that could be put into place on some of my sites and etc. Both training tools that I have, present a single project that is developed over the course of the training. This is good, except when you just need a few Flex components, menus, etc, etc. If I wasn't looking to have the entire site done entirely in Flex but wanted to use some Flex tools/components/applications, things would be different than if I were creating an entire web application within Flex, with XML or a database. The training I mentioned does not get into deploying the content and the Flex Designs until one is far into the text or training. I won't always need that much knowledge each time I create something using Flex CS3. So, if anyone could recommend additional training material, online or texts, please let me know, Thanks, Bruce
RE: RES: [flexcoders] Using CSS with custom item renderers
One more note on this one:
Renderers have their TypeSelectors blocked for the styles:
backgroundColor
borderStyle
borderStyle is blocked because DataGrid/List has a borderStyle and if
you put a container in as your renderer, it would pick up that
borderStyle by default.
Similarly, backgroundColor is blocked, but also for another reason. We
want the renderers to not have a background so the selection/highlight
colors can be drawn behind them and show through.
We can add this to the doc.

Simply put, the IDataRenderer interface.
ItemRenderers are supposed to be encapsulated, if Adobe used anything
other than the styleName of the renderer's parent, they would be
breaking this encapsulation rule.
You could try un setting the styleName in commit properties and then try
your TypeSelector again. If that dosn't work, override
updateDisplayList() and unset it after super().

Re: [flexcoders] bug in setMonth() method?
parseDate.setMonth(++parseDate.month); Then that statement above gives different results to: ++parseDate.month parseDate.setMonth(parseDate.month); which gives: Sat Nov 1 00:00:00 GMT+ 2008 Sun Feb 1 00:00:00 GMT+ 2009 Mon Dec 1 00:00:00 GMT+ 2008 Sun Feb 1 00:00:00 GMT+ 2009 Thu Jan 1 00:00:00 GMT+ 2009 Sun (i.e. it behaves as you would expect) Shouldn't the two versions be executed the same way? - i.e. month is incremented from 11 to 0 by the ++month (causing the year rollover) and then this 0 is passed into setMonth which should just set it to 0 again and cause no rollover. The call to setMonth is superfluous (though personally I'd go with setDate(parseDate.month + 1)) but shouldn't actually be doing anything as in both above cases it's just being passed 0 and so should either cause a year rollover in both cases (which would be buggy but consistent) or in neither case, that it's different is a bit worrying.

Re: [flexcoders] Re: Use Cairngorm wihtout Dispatch
You mean if you change the name of a method on your controller? Sounds like you'd have the same prob if you change the name of the event you were listening to on your controller. You'd have to change the event back to the correct name in your controller (i.e. the same as changing the method name back), or change every view to dispatch the new event your were using in your controller (after finding them ;)). The diff is, using events it would fail silently, then you'd have to search to find the events being dispatched by your view, where as the view calling a method on the controller that had its name changed would show me errors before I compiled. -- Stephen Downs Addict, Tink Ltd. e: [EMAIL PROTECTED] t: +44 (0) 7730 838 785 w: http://www.tink.ws -- On 6 May 2008, at 11:48, Tom Chiverton wrote: On Sunday 04 May 2008, Stephen Downs wrote: What is the difference of the view knowing what event it has to dispatch, to it actually knowing the method on the controller it was to invoke?

Re: [flexcoders] Child items in custom component

Hello!
I am currently a bit clueless regarding using Flex components. I am
currently trying to port a .NET component to Flex. Only I have some
problems. In a simplified form the problem is that I am trying to add
childs to the component. The idea is to use public method to add nodes
to the component. The code could be:
var node: MyNode = new MyNode();
node.width = node.height = 125;
myComponentInstance.addNode( node );
The addNode-method is basically contains:
public function addNode( node: MyNode ): void {
_nodeContainer.addChild( DisplayObject(node) );
invalidateDisplayList();
}
The _nodeContainer is a Sprite class which gets created in the
overriden
createChildren-method. Now I would be expected that the MyNode-

(which just draws a simple rectangle 125x125) would be shown. Sadly
enough, this is not the case.
Does anyone know what should be done to get this working?

Re: [flexcoders] Re: Use Cairngorm wihtout Dispatch
I'm not saying it's a major problem that we come across often, but when taking on other people's work, or working as a team it's something we have come across. We would expect all vars, methods, class, events to be named well, but we find it more efficient to error the project through changing a method name, than to do a find in files. We want to keep things as simple as possible. The point I was making as that just because events are used on the view instead of it accessing controller methods directly it doesn't necessarily de-couple them, since in most cases the view is relying on its events being picked up and acted upon. If my previous statement is true for you and your team, there's really no need to go down the event road, as it does introduces more complication and with it more time to implement. Just to clarify we don't take this approach on components, but we do for views/screens. On 5 May 2008, at 01:37, Jim Hayes wrote: I've not really had those problems myself Tink. I don't dispatch any standard cairngorm events, instead I have events that extend it and are (usually!) fairly well named to reflect what's happening. Maybe that's because for me they normally carry some data, and I like that data to be as strongly typed as is practicable. The command/delegate will usually follow the same naming, so I may have SaveBitmapEvent + SaveBitmapCommand + SaveBitmapDelegate, for example. So to find any particular event dispatch in my view, it's pretty easy to do a find in files on the project, though in practice I find I rarely need to. Likewise, finding the command it calls is pretty easy for the most part, as is the implementation in the delegate. Good point on the controller not listening, but I guess I've just got used to writing a shell version of my command, breakpointing it's constructor and checking it does get called when I expect it to before proceeding to fill in it's implementation. If not, then the frontController has it's fingers in it's ears shouting na na na I can't hear you :) It would be good if it could catch all cairngorm events and raise a warning if they were not registered, though. I have a feeling it wouldn't be too hard to extend it do that, but I've never felt the need myself. I'm sure we're both thinking don't make me have to think too hard, if at all, and I'm in broad agreement with you, but the 3 classes and controller entry approach does work for me (even if it is very tedious to write at the time). -Original Message- From: flexcoders@yahoogroups.com on behalf of Stephen Downs Sent: Sun 04/05/2008 14:08 To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Re: Use Cairngorm wihtout Dispatch I have to agree with MichNiu here.

The most useless part in cairngorm FrontCotroller and command
Just on my opinion, I really don't like to write the command for
every action and register it on FrontCotroller. I really think it
waste time, and It make debugging difficult! Sometimes you don't
know where do you get the result after you dispatched your Event.
Use A ServiceFacade to replace the front controller and the command.
I use a ServiceFacade to call the Delegate instead of the
controller and the junk command.
The idea is when the view page active some action. it will not
dispatch any event . it will call the service method from service
facade.
Here is example code form flexStore:
private function onLoadCatalog():void {
var event : LoadCatalogEvent = new
oadCatalogEvent();
event.dispatch();
}
to replace the event dispatch() my solution is :
private function onLoadCatalog():void {
ServiceFacade.getInstance().loadCats();
}
The ServiceFacade .loadCats() method call the delegate and service:
public function loadCats():void {
var handlers : IResponder
= new Responder
(onResults_loadCatalog,fault);
getDelegate(handlers).loadCatalog();
}
Use this way, I don't need create any front Controller and
command. I also get the benefit from Cairngorm Service Locate
Delegate and Model locator.
Any suggestion or Criticize is Appreciated

Here's how the code works in general:

- The selected image's name will be appended to a URL where the

- Check to see if newImgURL is existed in the associative
array. If it
is existed, then load the cached-bitmap else pass newImgURL to
imageObj.source.
- If it's passed to imageObj.source, the imageObj will throw
a complete
event. On the completeEventHandler, cached the imageObj's Bitmap

associative array.

Subject: Re: [flexcoders] Dynamic Instance Problem
Hi Dale,
did you reference the class somewhere in your code?
It needs to be compiled into the swf in order to instantiate it
dynamically.
My personal preference is to do this with a static code block:
{
MyClass1,
MyClass2
}

Re: [flexcoders] Re: Fade effect on a canvas
Changing from one child to another actually requires 2 effects. You see the first fade out, then the second fades in. PairedStackEffect enables you to combine the 2 effects into one. http://www.tink.ws/blog/pairedstackeffect-fade-squash/ There's a fade example there which might be what your after.

How would I prevent this? Is there a way to treat all of the visuals in the canvas as a single entity whose alpha is faded out? thx! -Matt

I think the original poster was looking for something like
graphics.drawText(Hello, format);
But there are (alas!) no APIs in the Graphics class that know how
to render a text string. Only TextField knows how to do that.

There is a way to draw a string to an graphical control (i.e.
Image) as:
private function drawStringOnImage( string:String, image:Image ):void
{
var t:UITextField = new UITextField();
t.text = string;
var b:BitmapData = new BitmapData( t.textWidth, t.textHeight,
true, 0x00 );
b.draw( t );
image.source = new BitmapAsset( b );
}
If you wanted to draw this on something like the canvas… well – you
*could* take a dynamic skinning approach.

Is there any way to write/draw text directly to a Graphics object?
For that matter is there
anyway to draw text (single line of static text) into a Canvas? I
suspect that the answer is no,
having searched and searched... but maybe there's some obscure
utility class that I've
overlooked.

RE: [flexcoders] Skinning in Flex - What a nightmare!!!
Hi,
There are several places to start with skinning doc:
- The Flex Developers Guide has a chapter on skinning. You can find it
here: http://livedocs.adobe.com/flex/3/html/skinning_1.html
- You can download and install the Flex Skinning Extensions for Adobe
tools, such as Flash, Fireworks, Illustrator, and Photoshop. These
include templates for all Flex skins. For more information, see

Subject: [flexcoders] Skinning in Flex - What a nightmare!!!
Please help
There is virtually no documentation on Flex skinning. I am really
struggling with border sizes and content sizes with custom skins, in
particular Panel skins using the borderSkin property.
I'm currently trying to skin an Alert box. I have the following
properties set:
Alert {
color:#ff;
borderSkin: Embed(source=flex_skins.swf, symbol=Panel_popupSkin2);
headerHeight: 30;
paddingTop: 20;
paddingBottom: 4;
}
My content only just fits, after much pixel pushing. It is still not
perfect as it is all squashed in. I have tried various things, that
have had no effect such as:
- tweaking the scale-9 borders in the .fla symbol
- setting verticalGap in the style
- setting borderThickness in the style
This is very frustrating as there only seems to be 1 definitive
document on skinning[1] which doesn't cover detailed concepts like how
to structure the .fla symbols.
[1] http://www.adobe.com/devnet/flex/articles/flex_skins.html
http://www.adobe.com/devnet/flex/articles/flex_skins.html (also
documented in Flex Help)
Where could I find out more information on skinning?

Subject: [flexcoders] Custom component with custom style - help please
I've made a custom component and on it I want to place a custom style
named waxColor. I started by simply creating getter/setters for
waxColor. Worked great when I include waxColor=#F0F0F0 to the mxml,
but I want this to be property driven. So I added
[Style(name=waxColor, format=Color, type=unit, inherit=no)]
to my as file. I then coded:
override public function setStyle(styleProp:String, newValue:*) : void
override public function styleChanged(styleProp:String) : void
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number) : void
to do what I needed. In my component that instantiates my custom
component I do myComp.setStyle(waxColor, 0xF0F0F0) and it works great.
But, the entire reason that I've added this as a style was that I
wanted to control the color via a style sheet. So in my css file I added
.wax {
waxColor: 0xF0F0F0;
}
and removed the setStyle code. Now my mxml does not have
waxColor=#F0F0F0 and instead has styleName=wax. This does not
work. I have trace statements in all of my overridden functions and
while styleChanged gets triggered, never with styleProp of waxColor.
setStyle is never called.
What am I doing wrong? I really want waxColor to be able to be set
via my css file.
Thanks,
Dale
Re: [flexcoders] Flex communication with WCF(.net 3) webservice issue
We got Flex 3 talking to WCF (Windows Communication Foundation for the curious, a .NET 3.5 thing). I don't recall if we saw the same errors as you but to get it to work we had to flatten the WSDL as Flex didn't like the way WCF WSDL involves 'including' lots of little WSDL files together. I'm not sure how you do this but our .NET guy did it in about 10 minutes so I guess it's easy if you know what to do.

[flexcoders] Embedded fonts not working in Flex 3?
Hi all,
I downloaded the 3.0.0.477 build from opensource.adobe.com and did a
few simple test cases. The ff mxml failed to compile:
==
?xml version=1.0?
!-- fonts/EmbeddedFontFace.mxml --
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
mx:Style

}
/mx:Style
mx:Panel title=Embedded Font Applied With Type Selector

mx:Button label=Click Me/
mx:Label text=Label/
mx:TextArea width=400 height=75 text=The text
uses the myClass class selector.
/
/mx:VBox
/mx:Panel
/mx:Application
==
The code is copy-and-paste almost exactly from an example in the
livedocs...I just changed the font from Myriad Pro to Arial.
Compiling the above gives a null pointer exception:
