Re: [flexcoders] Problem with events, how event dispatched when state change?
Hi Daniel
If you use a binding between a value of you model and the
selectedIndex of your combobox,
the control updates automatically whenever you change the model property.
//in MyModel
[Bindable] public var selectedIndex : int
//in MyForm
mx:ComboBox selectedIndex={ myModel.selectedIndex } .../
Now whenever you change myModel.selectedIndex, the combobox will
update automatically.
You can find some more examples of binding in the docs.
Cheers
Ralf.

There are lots of depending ons here, but in general, there is nothing about flash or AS3 that makes processing data slow. In fact it can be quite fast. The issue is how to architect it on the client side. For example it probably doesnt make sense to load all this data into a datagrid. But it can still be on the client in stoage focused data structures. Really flash is entirely capable of loading and handling large datasets. Adobe has announced their desire to move all their apps to flex, and in general, I view flex as just as capable as a regular desktop development environment for which one would never say oh you cant load all that data into excel for example. Flex isnt as fast as C++ but it really is getting there and for most applications the speed difference doesnt matter. Just like today we do not hesitate to do stuff in java vs C++. The point is you can build highly performant client side apps in flex, and with things like AIR being introduced, we need to get comfortable with that idea.

Re: [flexcoders] There has been an I/O Error: Error #2038
FileUpload is probably one of the hardest functions to troubleshoot in Flex owing to the lack of detail. My personal wishlist is for Adobe to enhance upload function with robust error details. Even if only returning the literal error as output by the server. Meanwhile the method I use is to first develop the upload using an HTML form which can reveal error details. Then migrate to Flex implementation once all the kinks have been worked out. FlexCoders wrote: FLEX 2 I have a Flex upload project that gets this error at the end.

1067: Implicit coercion of a value of type flash.display:Bitmap to an
unrelated type mx.core:IFlexDisplayObject.
on line:
DragManager.doDrag(dragInitiator, event, dragProxy);
Do you maybe know how can i solve this?
thank you

I would like to use my original drag source UIComponent as dragProxy

public function dragItSubs(event:MouseEvent):void{

// Call the DragManager doDrag() method to start the drag.
DragManager.doDrag(dragInitiator, event, dragProxy);
}
then the original UIComponent (which is a drag source) is used as
dragProxy while dragging it but that same component dissapears from
its original position as soon as dragging starts. How can i accomplish
that drag source UIComponent's image is used as dragProxy but the
same source drag UIComponent is intact while dragging?
thanks in advance

RE: [flexcoders] [Design Mode] FlexBuilder 3 Design Mode not working
It has nothing to do with code. If I just create a new flex project, put one Button in the code, switch to design view, I get nothing... In design view, if I drag a Button to the stage, I get the sign saying that it's impossible to drag the item there... In Design Mode, the Flex Properties Panel says : 'This panel is only available in Design Mode'. I'll try reinstalling FlexBuilder 3 Plugin. Is there a Plugin needed for the design view?

[flexcoders] Progress Bar Item Renderer
I'm trying to create a progress bar item renderer, but I can't get the
value of progress bar to bind:
mx:AdvancedDataGridColumn headerText=% Complete width=100
mx:itemRenderer
mx:Component
mx:VBox
mx:Label id=lbl
text={data.percentageComplete}/
mx:ProgressBar label=%3%% maximum=100
width=100%
mode=manual source={data.percentageComplete}/
/mx:VBox
/mx:Component
/mx:itemRenderer
/mx:AdvancedDataGridColumn
You don't appear to be able to bind the value using source. What am I
doing wrong?
[flexcoders] Re: Progress Bar Item Renderer
The source-property is bindable, though as stated in the docs:
Refers to the control that the ProgressBar is measuring the progress
of. Use this property only in event and polled mode. A typical usage
is to set this property to a Loader control.
Since you set your mode to manual, the source-property will be ignored
and as a consequence, the binding won't be executed.
When using 'manual' you could try using the setter method, again from
the docs:
public function setProgress(value:Number, total:Number):void
Sets the state of the bar to reflect the amount of progress made
when using manual mode. The value argument is assigned to the value
property and the maximum argument is assigned to the maximum property.
The minimum property is not altered.
When needed for binding, take a look at BindingUtils.bindSetter

[flexcoders] Re: Where to do heavy lifting in a Flex app? (no threading?)
Maybe he confused the SDK/compiler with the player. especially since I think I saw a call for talented assembly programmers to work on the Flash player. I doubt you could squeeze *that* much performance at such a small size with anything else (actually, two players in one now-a-days) but this isn't solving the initial problem that sparked this thread (if you pardon the pun - and irony). Sadly I can't think of a solution to get that smooth transition, except a possible rethink of what's happening (gut feeling only)
[flexcoders] SandBox, crossdomain.xml
hey people, got some questions about crossdomain.xml i got a swf file that loads up under https//www.test.com and the swf file also load in https. now I had to make my crossdomain calls http so i can call http://sub1.test.com. We only have a SSL cert for www.test.com. So if I try to make a crossdomain call to https://sub1.test.com it will not load the crossdomain.xml. Is this because the https://sub1.test.com doesn't have a SSL cert? If I got a wild-card SSL cert for *.test.com would my sub1.test.com calls over https work? Can I even make corssdomain https calls? any help would be good.

I have been attempting to replace the basic rollOverEffect with my own custom version that allows some extra validations but it doesn't seem to want to work the same. When I play a glow effect it works but if I continue to leave the mouse over it the effect disapears soon after it completes the effect. What property do I need to set to replicate the rollOverEffect?
[flexcoders] Re: Progress Bar Item Renderer
Seems to me that Flex doesn't like scripts anywhere but in the root of
a document. I do not have any experience with item-renderers, nor do I
have with loaders, but this is my guess:
If you create the ItemRenderer as a custom mxml-component, then you
should be able to set a script-block in this file.
Again this is just my wild thinking, but I hope that with it, you, or
others in here, might get to a working example.
Good luck,

Hi Guys, I have a problem with the LinkButton in Flex 3 Beta 2. It isn't showing the character 'q' entirely. The bottom of such characters is not shown. If I adjust the height of a label, it just disappears... Strange... If I add labelPlacement=bottom the q appears... But there's no Icon in my LinkButton... So this is a workaround.

Hello there, The url is www.KickPlay.com and is a site where you can play casual games like solitaire and some other simple ones. The cool thing is that you can personalize the games with your own face or any other image you want. You can get pretty creative with the games and make them political, funny, holiday, etc... You can send them to a friend, post them on your website or Facebook page too, if you have one. It would be great if you have 10 minutes or so to play a couple games then try to personalize one or two and give us your honest feedback on everything. Thanks!
[flexcoders] Custom itemRenderer using Label Question
Hi,
I'm using the following code to set the data of an extended Label
being used as an itemRenderer in a datagrid. The editor for the cell
is a combobox. What I'm doing is taking the data value sent down for
that cell (a number), looking it up in the dataprovider of the
combobox and displaying the corresponding label in my custom Label
widget. What I'm wondering is if this is the best way to do it. In
particular, the part that concerns me is that I'm creating an instance
of the combobox editor to get the dataprovider collection to search.
Any thoughts would be greatly appreciated. Thanks, John

super.data = value;
var cbr:ComboBoxRenderer; // will contain

selected cell's comboBox
if (listData != null) {
dg = DataGrid(listData.owner);
cbr =
dg.columns[listData.columnIndex].itemEditor.newInstance();
dp = cbr.dataProvider as ArrayCollection;
// now iterate through dp to find a matching
data value, when

[flexcoders] Re: Flex grid to serve 100K-1mil rows
Hi all, Thanks for all your responses. Maybe it'll be better if I described our use case in bit more in details. Our users send us trade file (sometimes has ~50K trades in it currently). And let say all of the trades have an invalid broker code, and all got kicked out, the user will have to go in and change the broker code 1 by 1 that could take them hours. Therefore, the ability for our users to perform mass actions on the dataset (either client side or server side) would be a huge win for us. Once again, thanks all.

Sounds like a good idea - but I can already access all of the fields of each object without casting. What does casting buy me in this situation?

The statement ac = event.result.products.rug; changes the pointer ac so that instead of pointing to the ArrayCollection that you new'd, it now points to the rug. By the way, this makes no sense since ac is typed as an ArrayCollection, while products.rug is presumably NOT an ArrayCollection. The compiler can't report this error because it doesn't know what type event.result is. If the result object has some type, you should cast it: ac = SomeResultClass(event.result).products.rug why can I not directly manipulate my original object from within the function? You can access and change the state of that object within the function.. For example, within the function you can do things like ac.addItem() trace(ac.length) to manipulate your ArrayCollection. But if you want your function to make collectionAC point to a different object, you must write collectionAC = ... inside that function.

I have a custom event that holds an array element. When I dispatch
an
event from a pop up window - by dispatching it from the
mx.core.Application.application object - with data assigned to the
array the event fires correctly, however, the data array element is
no
longer assigned any data. Also the event object still has the
data:Array property, so the program recognizes it as my custom
event,
it just does not have any data anymore. Why is this?

Use trace() to display the xml content you are getting back from the

Consider using a result handler instead..
Also, specify resultFormat=e4x. The default converts your xml to a

if I either need a [] somewhere in the dataProvider or I need to put

[flexcoders] Re: Where to do heavy lifting in a Flex app? (no threading?)
Looks like quite a few people are tackling the same problems, or have at least had it in the back of their minds. I understand the history of the flash player, what kinds of applications it's been used for, and I also understand how large an undertaking it would be to make the current Flex components thread-safe, etc. The big problem I have, and I think others have already touched on it, Flex and AIR are being marketed as the evolution of RIAs, and I honestly believe they are. But there are some pretty big hurdles to overcome to make the user experience as rich as possible, the development as painless as possible, and the RIA as powerful as possible. In my case the server is doing a TON of the work, so offload it to the server is already pretty much the case. That being said you can't fine tune ALL your data for a particular view. The Flex UI I'm working on is just one of the consumers of the XML data available on the server. I get a large chunk of XML, I process it, and then I need to make intelligent decisions about updating various data models and the view reacts to those changes. The problem is when all of this happens serially in event listeners, the UI is blocked. I hear a lot of suggestions to split the work up and do it in the next frame. Most of my work prior to Flex has been Java and similar languages, so I'm still getting used to the idea of thinking in frames. Can someone give me a good example of how to split this work across frames? Most of the work is being done in the result of Cairngorm commands, which aren't DisplayObjects so callLater() isn't available. Do I need to have these commands somehow listen for a frame change on the application? That seems like a very un-clean way of handling this. I've been considering some of the suggestions of using a Timer. I may create a WorkQueue where I can pass function references and parameters. Start a timer and have the WorkQueue listen for the timerEvent and process the next action. I think it'd be great to hear from more Adobe employees such as Alex about how they are currently handling problems such as this, and any possible plans for the future of Flex and AIR to handle more client-side processing. Maybe a series of blog posts are in order. Thanks again for the great responses.
[flexcoders] FlexBuilder 3 Beta 2 charting and license
Hi, I realize there were several messages about this before, but I'd just like to clarify: Currently, with the FlexBuilder 3 Beta 2 trial, when I try to use the AdvancedDataGrid, for instance, the running Flex application displays a watermark to the effect that it's the Flex data visualization trial. I have a FlexBuilder 2 license, but not a charting license. If I purchased a license for Flex Charting for the Flex 2 SDK, would that license key make the watermark disappear in the AdvancedDataGrid in FlexBuilder 3, also? Thanks, -- Frank

Subject: [flexcoders] Custom itemRenderer using Label Question
Hi,
I'm using the following code to set the data of an extended Label
being used as an itemRenderer in a datagrid. The editor for the cell
is a combobox. What I'm doing is taking the data value sent down for
that cell (a number), looking it up in the dataprovider of the
combobox and displaying the corresponding label in my custom Label
widget. What I'm wondering is if this is the best way to do it. In
particular, the part that concerns me is that I'm creating an instance
of the combobox editor to get the dataprovider collection to search.
Any thoughts would be greatly appreciated. Thanks, John
override public function set data(value:Object):void {
super.data = value;
var cbr:ComboBoxRenderer; // will contain renderer for this cell
var dg:DataGrid; // reference to grid containing this cell
var dp:ArrayCollection; // dataProvider of selected cell's comboBox
if (listData != null) {
dg = DataGrid(listData.owner);
cbr = dg.columns[listData.columnIndex].itemEditor.newInstance();
dp = cbr.dataProvider as ArrayCollection;
// now iterate through dp to find a matching data value, when
found put its label in the Label widget
var dpLen:int = dp.length;
for (var j:int=0; jdpLen; j++) {
if (dp.getItemAt(j).data ==
data[DataGridListData(listData).dataField]) { // found match
this.text = dp.getItemAt(j).label; // + + dp.getItemAt(j).data;

It is actually - especially because you can unit test it without the ui
I'm using a model class for all my comboboxes, which contains the
dataProvider and a selectedIndex property.
However, if you don't want to go down that route, you can either use a
binding function,
if the whole dataProvider is replaced you add CollectionChange
handling to your dataProvider
if it is changed. You can use myArrayCollection.itemUpdated(..) to
trigger this event.

[flexcoders] Custom List component Height Issue
Hi all, I created a custom item renderer and in it I have: Canvas HBox Text /HBox /Canvas The text inside Text includes spaces like /r, so most items take up at least two lines. However my problem is that it only seems to be rendering the first line of text and is not displaying the rest. If I set the height strictly it'll display the full text, but this would seem odd for items that are only one line of text. Anyone have issues/solutions with variable heights in list items?
[flexcoders] Code for preventing browser caching of SWF
I'm trying to stop the client's browser from caching my flex app swf so that each time they call the html wrapper they get the latest swf. I've found some suggestions out there for accomplishing this, and I think adding the myapp.swf?build=12341234 (some timestamp) solution looks cleanest, but I was wondering... Has anyone modified their index.template.html wrapper so that each time you compile your app it auto-generates and appends that random (or time based) number like this? Anyone know if there's an example out there I can look at? It would be nice if this was automatic and I didn't have to implant a new number in the wrapper each time by hand. Thanks Darren

[flexcoders] HorizontalList drop indicator weirdness
Hello! I have a HorizontalList with drag drop enabled, so you can re-arrange stuff in it. For some reason in HorizontalList, the drop indicator line appears on top of an item instead of on the side of the item like in TileList. I was wondering if there's a way to change this. I was trying to reason why this is happening and my guess is HorizontalList is probably a TileList with direction=vertical and max row set to 1. Thus, it is working as if it is a tall 1-column list and that's why the drop indicator is on top of the item. I appreciate the advice!

Hi flexcoders! I have a VScrollBar and HScrollBar that both loads identical skins (it's simply some PNGs).

Anyone has an idea? Thanks!
RE: [flexcoders] Re: Where to do heavy lifting in a Flex app? (no threading?)
Rats, I've been singled out again. I was sort of hoping not to get too involved in this topic, but, since you asked... First, a little about me: I'm an old DOS/Windows app developer turned AS developer. I wrote code that had to fit in 640K, and later in Windows 2 which were both single threaded environments. I've done some multi-threaded Windows 3 code in the past, but know almost nothing about servers, and you can print out all of the Java code I've written and still not cover your dining room table. My background probably makes me more willing to jump through hoops to make things work in the environment I've been given. I'm all about leveraging what's there and will sacrifice some maintainability in order to deliver a great user experience. I've written tons of assembly code, designed and implemented a custom overlay infrastructure to get MBs of code to run in 640K and lots of other 'crazy' things. To me, the Flash Player is a new paradigm/platform. I don't even consider it to be single-threaded, but rather, completely event-driven. We can wish it was Java, Windows XP, Linux, etc, but it isn't. It was designed to optimize animation in a browser plug-in environment, in the smallest possible download so as to encourage ubiquity. Plenty of studies show that proper use of animation in a presentation can significantly improve the chances your application will achieve its goals of learnabiity, reduced errors, task completion time, retention, etc. To me, that is the promise of ria. It is not an opportunity to offload servers. In fact, the whole principle of web-hosted apps is the notion of zero-install, i.e, not having to visit every desktop. The more work you push into your client, the greater the chances are that you'll have to visit them to upgrade their box. So, if I were in your shoes, I'd be trying to design apps that leverage these advantages, while working around the limitations via things like pseudo-threading, paging data, etc. However, I'm not in your shoes. I've never built and delivered a RIA. I'm stuck in a cubicle, improving the framework, but I never really have the time and opportunity to use it from your perspective; We rely on feedback from those of you who are in the trenches. I can only offer unproven ideas. Will there be threading in some future Flash Player? Probably. Do you need threading now? Probably. Can pseudo-threading solve it for now? Probably. Maybe I'll try to put together a general pseudo-threading engine. Keep in mind one thing about threading: While it will help you show progress or spin a busy cursor while cranking lots of data, if the user is waiting for its completion as part of the workflow, it will still seem painful to the user. It will always be better to try to design the app to avoid any serious cranking in the workflow. That's why paging of data is useful. If your DataGrid can only show 8 rows of data, go get 8 rows and get the rest later. Show a low-res thumbnail and get the high-res later. Use your imagination, learn how to think in this new platform, and design for the user, and forget for a moment that their computer is a fast as the server. After all, they may be running their virus scan at the same time as your app, or watching some video, so you cannot always factor that CPU into your load-balancing equation, and it in theory, it is the user's experience that matters most. Of course, I could be wrong... -Alex From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of danielggold Sent: Monday, November 12, 2007 9:11 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Where to do heavy lifting in a Flex app? (no threading?) Looks like quite a few people are tackling the same problems, or have at least had it in the back of their minds. I understand the history of the flash player, what kinds of applications it's been used for, and I also understand how large an undertaking it would be to make the current Flex components thread-safe, etc. The big problem I have, and I think others have already touched on it, Flex and AIR are being marketed as the evolution of RIAs, and I honestly believe they are. But there are some pretty big hurdles to overcome to make the user experience as rich as possible, the development as painless as possible, and the RIA as powerful as possible. In my case the server is doing a TON of the work, so offload it to the server is already pretty much the case. That being said you can't fine tune ALL your data for a particular view. The Flex UI I'm working on is just one of the consumers of the XML data available on the server. I get a large chunk of XML, I process it, and then I need to make intelligent decisions about updating various data models and the view reacts to those changes. The problem is when all of this happens serially in event listeners, the UI is blocked. I hear a lot of suggestions to split the work up and
[flexcoders] Drag-scroll in a List not working on Mac (?)
I have a List that has drag drop enabled so you can rearrange the items. On Windows, while you are dragging an item, you can go near the bottom of the list and it'll scroll if there are more content and it's scrollable. I can't seem to get this behavior on Mac. Is this a known bug? Thanks!

[flexcoders] Re: Where to do heavy lifting in a Flex app? (no threading?)
With the help and suggestions in this thread I'm currently looking through the app I'm working on and trying to decide what I need to gut. This is where examples from others can really help out, and a Pseudo-Threading-Engine example would probably be golden. I think any documentation about the Event-Driven model in Flex/Flash should have *** all over it to remind those of use who came from multi-threaded event driven applications that any listeners will be processed serially when an event is dispatched. I think that's where my mind took off with the event driven model and ran, thinking those listeners would be processed in some background Event thread. I have to be very careful how I structure this application because I am working in a team of ten developers. The performance problem I've been seeing has been exacerbated by the fact that other developers have registered their components as event listeners for many of the events I'm dispatching. With each new listener, my function becomes slower and slower as each listener action is basically added in-line. Going back to the drawing board on this application architecture.

[flexcoders] Re: Flex grid to serve 100K-1mil rows
Have you considered paging the dataset in the ActionScript, but applying the operations to the original ArrayCollection/Dataset? What I mean is, although the grid may only show say 15 records at a time, the dataset is still stored as an AS object and could be adjusted client side, and the current page reloaded. I'm imagining the bottleneck isn't the data structure, but rather the DataGrid rendering time. The other option which has already been mentioned would be to do it server side. You could also roll this into AIR and use the built in SQL Lite implementation for added ease and speed. -- William --- In flexcoders@yahoogroups.com, letterpigeon [EMAIL PROTECTED] wrote: Hi all, Thanks for all your responses.

Without understanding his application and architecture I cannot opine on whether it is better to do this on the client or server.

[flexcoders] ComboBox that opens by default

Hello everyone, Kevin here from San Francisco building an application

In my ViewManager, which I am extending from Sprite, but could be as

abstract whatever Components may be rendered at runtime.
Thanks for any pointers,

RE: [flexcoders] Re: Reference variables / pointers / hex heap addresses
I think your XML is getting autoconverted into untyped ActionScript objects (because you haven't specified format=e4x).

You can access and change the state of that object within the function.. For example, within the function you can do things like ac.addItem() trace(ac.length) to manipulate your ArrayCollection.

[flexcoders] DataGrid not populating from XMLListCollection - namespace issue?
I've been trying to get a DataGrid populated from a WebService and
having much trouble. I'm wondering if the issue might be namespace
issues, but I'm confused by the usage and syntax of namespace from the
posts I've found here on that. There is no data in the DataGrid, but
it does appear to flicker and slightly resize it self when I call the
service so it looks like _something_ is going on. I've bound the
service response to an XMLListCollection so I can trace() it and I can
see the XML tree that should be displayed in the DataGrid.
Any ideas why it's not working? Would appreciate any help, been
banging my head on this for days now. Thanks.

RE: [flexcoders] classes
The compiler will not let me add Bla3 and Bla4 without throwing an

In AS3, an overriding method must have exactly the same method signature
as the method being overidden. The signature includes the number and
type of the parameters, the return type, and the accessibility modifier
(such as public, protected, private, etc.) If you need to add
parameters, define a getBla2().
it also expects you to data type the methods
The type of a method specifies the data type of the value that it
returns. If it doesn't return a value, declare it to have type :void.

Subject: [flexcoders] classes
I am not a Flex user, I don't know how to do that yet. But here is my
problem anyways.
I have been working on my final project for school. I set up all my
classes. I was having difficulty with getting them to work. My base
class contains all the data that is necessary to set up the all the
class that follow. For example.
package packageName{
//the base class
public class A{
//the base class method
public function getBla(bla1, bla2){
bla1 defined...
bla2 defined...
}
}
package packageName{
//on of the subclass's
public class B extends A{
//subclass method
override public function getBla(bla1, bla2, bla3, bla4 ){
bla1 and bla2 are inherited automatically
bla3 and bla4 are defined
}
}
package{
import flash.display.Sprite;
import packageName.*;
//the main class
public class mainClassName extends Sprite{
private var theBla:B;
public function mainClassName(){
theBla.getBla();
}
}
}
Anyhow it didn't work. It seems that overriding does just that and
only that, overide. The compiler will not let me add Bla3 and Bla4
without throwing an error. Also I can't remove the keyword override
because the compiler thinks I am trying to override the Method when all
I am really trying to do is update the method.
Another problem I am trying to work out is data types. Not only
does flash expect you to data type your parameters, but it also expects
you to data type the methods. I am sure that I have some sort of
misunderstanding about this, but here is my flawed interpretation
anyways.
public function getBla(bla1:String, bla2:String):String{
bla1 = 'bla bla bla';
bla2 = 'bla bla bla';
}
But what if I want to add a string and a numeric type in the same
method? Then what what datatype do I declare my method to be?
public function getBla(bla1:String, bla2:int):???{
bla1 = 'bla bla bla';
bla2 = 123;
}
And if I am actually successful overiding or updating or whatever a
method in a subclass, then how do I data type the subclass or base class
for that matter?
//base class
public function getBla(bla1:String, bla2:String):?String?{
bla1 = 'bla bla bla';
bla2 = 123;
}
//subclass
public function getBla(bla1:String, bla2:String, bla3:int,
bla4:int):???{
bla3 = 456;
bla4 = 123;
}
Also, if you notice that some of my terminology is off, then please feel
free to correct me. I am still a learning the basics.
Thanks,

Sorry this is taking so much back and forth.

Still doesn't work, would it be too much to ask you to post that
code
to
draw
bitmap data onto UIComponent? I tried to implment that idea with
following
code:
public function dragItMain(event:MouseEvent):void{
// Get the drag initiator component from the event object.
var dragInitiator:UIComponent = event.currentTarget as
UIComponent;
// Create a DragSource object.
var dragSource:DragSource = new DragSource();
dragSource.addData(dragInitiator, main);
var target:UIComponent = event.curentTarget as UIComponent;
var bitmapData:BitmapData = new BitmapData(
Math.round(target.width /
target.scaleX),
Math.round(target.height /
target.scaleY),
false);
bitmapData.draw(target);
var bitmap:Bitmap = new Bitmap(bitmapData);
var bitmapHolder:UIComponent = new UIComponent();
bitmapHolder.addChild(bitmap);
// Call the DragManager doDrag() method to start the drag.
DragManager.doDrag(dragInitiator, dragSource, event,
bitmapHolder);
}
But all i got is the following error:
ArgumentError: Error #2015: Invalid BitmapData.
at flash.display::BitmapData$iinit()

Sorry, try BitmapAsset instead of Bitmap, which extends Bitmap and
implements IFlexDisplayObject. If that doesn't work, I have code
to
draw
the bitmap data onto a UIComponent.

I followed your advice Dan and used this code:
public function dragItSubs(event:MouseEvent):void{
// Get the drag initiator component from the event object.
var dragInitiator:UIComponent = event.currentTarget as
UIComponent;
/
var target:UIComponent = event.currentTarget as UIComponent;
var dragProxy:Bitmap;
var myBitmapData:BitmapData = new BitmapData(target.width,
target.height);
myBitmapData.draw(target); // draw target onto bitmap
dragProxy = new Bitmap(myBitmapData);
/
// Call the DragManager doDrag() method to start the drag.
DragManager.doDrag(dragInitiator, event, dragProxy);
}
But now i get the following error:
1067: Implicit coercion of a value of type flash.display:Bitmapto
an
unrelated type mx.core:IFlexDisplayObject.
on line:
DragManager.doDrag(dragInitiator, event, dragProxy);
Do you maybe know how can i solve this?
thank you

Use a bitmap of the target instead of the original target.

Re: [flexcoders] Grid lines in TileList
Darn. Any suggestions for the 2-d dashboard-style grid I'm doing? I've played around with PlotChart, but it wants numeric axes, which I suppose I could fudge now that I'm building an adapted model. The TileList is working OK, but I tried alternating colours, and they appear vertically no matter what I set the direction to. I've also had some success with nested repeaters, but always worry about the overhead, though in this case the data set won't be very large. Doing a DG with a data-driven number of columns looked harder, but maybe I'm missing something simple. On 11/12/07, Alex Harui [EMAIL PROTECTED] wrote: Yes. Only DG has this style. Am I correct that there is no style property to enable grid lines in a TileList?
Re: [flexcoders] Grid lines in TileList
I was also having trouble getting rotated labels on a PlotChart - if anyone has an example of that, I'd love to see it. On 11/12/07, Richard Rodseth [EMAIL PROTECTED] wrote: Darn.
