[flexcoders] Image Marquee
I am pretty new to Flex but a vet in the programming world so Action Script
3 is great and I think I am coming along quickly with it. I am trying to
create a footer bar 800w 60h that will display an animated marquee of all
the images i load from an xml file. I have about 30 images in there right
now. I am using a tile list to display them and the way I have it the first
8 are showing up. Is there a way to animate the rest of the images in a
scrolling animation or am I completely on the wrong track here? Here is what
I have so far, any help is greatly appreciated!

[flexcoders] Security Model
I am having a hard time understand the flash player security model. I am trying to write some web serverice examples and for everyone I keep getting the following error. Warning: Domain services.digg.com does not specify a meta-policy. Applying default meta-policy 'all'. This configuration is deprecated. See http://www.adobe.com/go/strict_policy_files to fix this problem. Is this a problem with me or with the cross domain policy on the providers side. If it is on there end it really does not make much sense to me. All of these web services work in the http request world so why doesnt it work here. Do I need to go around and start asking others to fix it or is this a problem on my end? Dan
[flexcoders] Flex Book
I downloaded a great component from http://www.quietlyscheming.com/blog/ and
I am trying to customize it and I am coming across a problem. The example
uses
mx:XML and if understand that is acompile time tag. I want to load the xml
at runtime so I changed the code. Here is my code and this is the error I
keep getting. Does anyone
know what I am doing wrong?

Re: [flexcoders] Flex Book
The problem with that is mx:XML is a compile time tag, the xml file will
change on the server.

Simplify your code by using the mx:XML tag and set it's source
property to the path to your XML.
mx:XML id=myXML source=data/images.xml/
Your xml might look like:
images
image thumb=assets/thumb1.jpg/
...
Then reference it as myXML.image.thumb.

Re: [flexcoders] Flex Book
Rob,
Great tip on using http instead of xml. The problem I am having now is I
think the component is trying to load before the service is completed. I
don't think the dataSet is filled when the component is setting up. I tried
to create the component in AS but it would not let me. Any help is
appreciated, I am racking my brain over this.

Well the component needs the data from the httpservice so somehow i need to
call the component when the service is completed.

Re: [flexcoders] Flex Book
While I see your direction I am just not sure thats what I want to do. The
xml needed is to display the 1st image and that needs to come from the xml
file. Is that what my problem is? Is the component looking for values before
they are available? It works using mx:XML/ and that makes sense since its
compiled.

Dan, I'd set the components dataprovider to an XML variable, and
initialise that variable as either empty or whatever the minimum xml
information needs to be to prevent the component getting upset about null
values. make that variable bindable.
Then, when you get the http service results, convert that to xml and put
it into the variable that the component is bound to, the binding should
result in the component updating. If binding isn't working (for whatever
reason), then just reset the dataprovider to the new xml from the http
result (and think about binding later if you have to).
Hopefully that should get you started on something that works, at least.

[flexcoders] Basic Air App
I am trying to build a basic air app using Flex 3. I have been writing some Flex applications with no problem but when I goto debug my AIR app I am having some issues. First off here is the basic code to create the app. ?xml version=1.0 encoding=utf-8? mx:WindowedApplication xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute title=Hello AIR mx:Label text=Hello AIR horizontalCenter=0 verticalCenter=0/ /mx:WindowedApplication When I try and debug Flash Player 9 opens and Flex Builder stays on Launching... for about 1 minute after which I see the following error. Failed to connect, session timed out. Ensure that. 1.) You compiled your flash application with debugging on 2.) You are running the debugger version of Flash Player. I am not sure why I get this message? If I am debbugging flex applications with no problem I should be running the debugger version of Flash player right?

[flexcoders] ColdFusion Structures in Flex
I am new to Flex and I have some questions about data types. I have a method in ColdFusion that returns a structure. I heard that this is automatically converted for me. I was wondering if anyone can point me to article that explains what types in CF are converted to in Flex. I put a break point on my result and it just looks like an object. A follow up to that is there a method that I can use that will return the type of object I am working with? - Completely separate how does the data provider for different components such as the tree and datagrid work? I have datagrids working with arraycollections and xmlcollections. Is there a specific format for the dp to work? Thank You Dan
Re: [flexcoders] ColdFusion Structures in Flex
Here is what I am trying to do and it may make more sense. I have an object
coming back from ColdFusion that contains a list of datasource names. When
reading through the docs I can tell i need an arrayCollection or
XmlLIstCollection to use as the data provider.
I also need to list the field names for each datasource underneath that so
should I just build that completely on the cf side before passing it back or
when the datasource + is clicked retrieve a list of field names.

[flexcoders] Scrolling Image Component
I built a custom component that allows me to scroll an image up the screen.
When you mouse over the image the animation stops and when you mouse out it
resumes. I also built in a click handler to open up a url. Here is the code
as well as the code I am using to instantiate it. My question is how could
I go about nesting another component? You will see my want example I want
to be able to pass any number of images into the component. I am a newb so I
am not sure how I can keep nesting.

Re: [flexcoders] Problems accessing a class method from an mxml file
The static error leads me to believe you have not instantiated your object
yet. Have you created the object or are you directly trying to call the
method?
var obj:myObject = new myObject();
obj.getData();

getData through a reference with static type Class.' I've tried fully

[flexcoders] DataGrid Item Editor Question

about this because the fileReference object does not hold this data so I can
not give it a dataField. I am sure this is because Im a new, any help is

Re: [flexcoders] DataGrid Item Editor Question

[flexcoders] Component Questions
I built a small app that has 4 screens and everything is working great. I
want to learn more about breaking up the views into different components
before I move on to mvc in Flex. My question is lets say I have my main
application and then each of my screens are views. In my main application I
have a public variable called _client. On the first view I am trying to
access that object and the compiler is telling me it is undefined. In my
code you will the line _client = selected.
My question is how does the component know about the data declared in the
main application ?

I know about the _ for private variables, I am just in the process of

Re: [flexcoders] Component Questions
Ok, I re wrote the 1st screen into a component. Here is the code for my
component. When a user selects a client from the data grid I want to
dispatch an event of clientSelected My question now is in my main app I
have the following code. How do I tell my main application to listen for
that event? addEventListener(clientSelected,onClientSelect) does not work?
Also all of my screens have next and previous buttons and when the app was
all in one file i was able to change states. Now that I am in a component
how can i change the state? Thanks for your help!!

Re: [flexcoders] Component Questions
I agree with you but is there an easy way to do this without diving into a framework right away? I understand frameworks in general but I am still learning the ins and outs of Flex. I am just trying to go up the 45 degree ramp instead of the 90 :) THanks! I seem to be in the minority opinion on this topic, and you must also know that I develop framework components and not full-fledged production applications, but if you are headed to MVC, there should be a central model class that contains the data, and the UI should only reference the model's data and not really own it, or the services that fetch the data, and when the UI is manipulated, the UI should update the model, and not really dispatch events for other UI to manage.

That is a ton of information Greg, thanks so much! I have viewed the Lynda videos before so I guess its about time to revisit them. I think once I wrap my head around how to move data around I will be ready to jump into a framework, after that sky is the limit! Thanks again for the info..

[flexcoders] Passing objects to components
If I want to pass a string to my custom component its pretty easy. Lets say
you have a custom button component and in that component you declare a
public var str, when you create your custom button you can simply do the
following.
local:CustomButton str=Hello World/
This works fine, but If I create an object and I want to pass an object into
the custom component it does not seem to be working. The button is displayed
but the button label is not displayed. Here is a quick example to show what
I am doing.
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute
xmlns:local=* creationComplete=init()
mx:Script
![CDATA[

public var obj:Object;
private function init():void {
obj = new Object();
obj.str=Hello Object;

You can also add the metadata tag to the class definition. That will
make all of the properties of the class bindable.

[flexcoders] Application Design
Maybe I am going about this the wrong way. I would like to explain my small
application and get some feedback. This app started out as 1 big file but I
decided to break it into smaller components. The main file is pretty small
as you can see below. What the main app does is use a view stack to display
the 4 screens I have broken into components. The first screen is the
client selector, once a client is selected you move on to the second screen.
In my client selector i dispatch an event that lets anyone listening know
that a client was selected, this custom event pushes the client data back to
the main app. The next two screens do something very similar in pushing data
back out of the custom component and the main app grabs.it. Once the first 3
screens are done its time to goto the reivew screen. The final screen needs
all of this data I have collected. As you can see below I simply try and
just pass the data but it does not work. Why can't I pass complex data but
strings will pass just fine? Im sure my being a newb to Flex has a lot to do
with this but I am just wondering 2 things.
1.) What am I doing wrong here?
2.) How do others layout a small application similair to this ?
Thank you so much for the help

Re: [flexcoders] Application Design
Thank you so much to everyone for your help and suggestions.
Tracy - I think it was because the objects are not bindable like you said.
In the review panel i was passing client but on startup its just an empty
object.
mx:ViewStack id=vs width=100% height=100%
views:ClientSelector id=startPanel vs={vs}
clientSelected=onClientSelected(event)/
views:FileChooser id=fileChooser vs={vs}
fileAdded=onFileAdded(event)/
views:Options id=optionsPanel vs={vs}
optionsSaved=onOptionsSaved(event)/
views:Review id=reviewPanel vs={vs} client={client}/
/mx:ViewStack
Instead of that i just set it in my custom event handler.
private function
onClientSelected(event:ClientSelectedEvent):void {
client = event.client;
reviewPanel.client = client;
}
** Thanks again for your help! So this is typical design of small
applications? I know i need to get into mvc approach but im still learning.

When its published the path looks more like this +projectroot +myproject -myswf.swf +cfc -Clients.cfc My question is what do others do about this. I know that in the web world I could read a config file based on live or dev. The problem is that through out this project I have really learned that I need to stop thinking in terms of basic web application development.

Re: [flexcoders] Remote Object Paths
Douglas,
The remote object path is used in the Flex app and therefor if its hard
coded it doesn't that get compiled? I think the flash vars is a nice way of
doing. I just threw in an initialize event, check to see if it existed and
if not set it and pass that path on to my views.
private function loadFlashVars():void {
// load flash vars
_ropath = Application.application.parameters.ropath;
if(_ropath == null){
// must be development
_ropath = MyProject.src.cfc;
}
}
This works for me but I am open to any suggestions, Im still learning.
Thank You

Re: [flexcoders] Debugging off when having multiple FB3 workspaces?
I am not sure if this is your problem but it may be causing it. One thing is to make sure all projects that you are not working on are close. If you right click on the project you are working on select close unrelated projects. This is more of an eclipse tip but it may be causing issues like this. Just a suggestion.

This is an AIR project so there shouldnt be any browser caching issues. In the past this has not affected me terribly since I only experienced it on temporary machines, my main dev workstation never had this problem...until today. All I did was switch workspaces to a brand new one and checked out from svn an earlier revision of the same project I was already working on. I then added a trace statement put a break point on the new line but as I step thru the code it is off by one line. I deleted the contents of the bin folders rebuilt but the problem persists. The only way I can make changes stick is to check into svn, blow away the workspace and redownload everything. The original Flex Builder 3 workspace does not seem to have this problem but all new workspaces do. In the past I have never had to work on two workspaces simultaneously so this wasnt a problem but now I need to be able to switch back and forth rapidly (using svn switch takes too long). Does anyone know how to solve this issue? Thanks, - Ivo

right, so have your server code (CFCs) sit in the same folder path in
dev, staging, and production so doesn't matter what Flex, Flash, HTML

can set application specific mappings in application.cfc. So, in your

[flexcoders] DataGrid Header Styles
I have some custom styles for my datagrid that apply to all datagrids. My
problem is that the rows of the grid get a rollover color close to black and
the text is white. The problem is with the header. When I roll over the
header the background color is black but so is the text so I can not tell
what the text says. Also the arrows are black so you never see those. Is
there a way to customize all of this or just tell the header to act normal
(don't apply styles)?
DataGrid {
textRollOverColor:#ff;
rollOverColor:#242424;

Hi,
I am building a product configurator, which creates an Estimate object. The
Estimate contains a Customer object and an array of Configuration objects,
each of which contains an array of Products.
The objects are built properly in Flex. But when I attempt to send the
Estimate object back to a ColdFusion CFC, the CFC acts as if there was no
parameter passed.
Specifically, if I call productService.saveEstimate(estimate), I get an
error saying the parameter estimate is required, but not passed in.
In debugging, just at the point of the RemoteObject (productService) call,
I can see that the estimate object does exist in the proper scope.
And if I create a string or array and put one in the method call:
productService.saveEstimate(blah), or
productService.saveEstimate(myArray)
... the method fires properly on the CFC. (The arg type in the CFC is set
to any for testing, so any data type is accepted.)
Why would the Estimate object (which exists) not be passed?
Any thoughts would be greatly appreciated.

[flexcoders] File Manager
I am not quite sure how to put this so I will try and explain the problem best I can. I built a small file manager utility that allows you to dbl click on folders and drill down through them. Once you are nested there is a toolbar icon that allows you to go back up. Most file managers have the up folder as the first row in the grid. Picture a data grid listing all of the folders first / all of the files next. I want to insert a blank row where the first column would have this up arrow image and on click would call my upNav method. Does anyone know of a way to dynamically insert this? I would think this needs to be done after the grid is created. Thank You Dan Vega

Re: [flexcoders] dynamic remote objects
That makes total sense because I also have an mxml tag in the document.I changed the code // setup the remote method var service:mx.rpc.remoting.RemoteObject = new mx.rpc.remoting.RemoteObject(); service.destination = ColdFusion; service.source = component.text; // the method needs to know about the remote object var operation:Operation = new Operation(service); operation.name = method.selectedItem.NAME; operation.addEventListener(ResultEvent.RESULT,loadGridData); operation.send(); and it still gives me the same error.

You either need to remove whatever tag or script that is using the MXML version of RemoteObject, or you need to fully qualify the class name in your statement, something like this: var service:mx.rpc.remoting.RemoteObject = new mx.rpc.remoting.RemoteObject(ColdFusion);' Hope that helps, Sid - Original Message From: Dan Vega [EMAIL PROTECTED] To: flexcoders@yahoogroups.com Sent: Wednesday, July 30, 2008 9:29:54 AM Subject: Re: [flexcoders] dynamic remote objects Ok, I figured out what I was doing wrong but I am still getting an error.

I add a bunch of text to the title windows content area. If I just add the
text it runs off the screen. I can set the width but that seems like a bit
of a hack to me. I know im probably just missing something dumb here.

[flexcoders] Selected Items in a datagrid
I have a datagrid with a custom renderer for the id column. What I want to
accomplish is letting the user select as many rows as they want by clicking
on the checkbox in the first column. When they click the export button I
will do some logic to export only the selected records to a txt file. Going
by the solution below how can i figure out what indexes are selected? Even
if i can't easily get a list of all the id's I can run over the index list
and get the actuall id's.
If there is a better way to do this and I am going about this the wrong way
please speak up! Thanks in advance!

[flexcoders] File Explorer
I am building a full featured file explorer and I am stuck on one part of the application. On the left hand side I will have a base root directory (root) and a listing of all directories that fall under it (no end). When you click on a folder they will show up in the datagrid to the right. My question is actually 2 parts. 1.) What approach should I take. Do I make one call to my server and build the entire folder structure, then return either and arraycollection or xmllistcollection or should I just grab the list of directories and show an arrow next to directories with sub directories indicating that there are sub directories. When you click on that folder make another call to the server to grab that sub directory list and so on. 2.) The second part of the question is i heard that If I am going to be updating this collection (deleting / adding / renaming directories) that I should be using an ArrayCollection. The question is when I have data like there is below, how do I break it down into parent/child nodes? Every example I have seen of the tree always uses xml as the data and in those examples its clear how to break down child / parent relationships. ** Any help on this how to move forward with this would be great help ** [0] (Object)#3 Attributes = DateLastModified = Sat Nov 1 13:21:02 GMT-0400 2008 Directory = H:\JRun4 hasDirs = 0 Mode = Name = bin Path = H:\JRun4\bin Size = 0 Type = Dir [1] (Object)#4 Attributes = DateLastModified = Fri Aug 3 21:55:23 GMT-0400 2007 Directory = H:\JRun4 hasDirs = 1 Mode = Name = docs Path = H:\JRun4\docs Size = 0 Type = Dir Thank You Dan Vega danv...@gmail.com http://www.danvega.org
Re: [flexcoders] File Explorer
Thank you so much! After screwing around with this for awhile I am finding that to be the real problem. When you get into unlimited numbers of sub directories the array collection becomes very hard to manage. I think to return my list of files an arrayCollection will work just fine but for the directory structure I am going to produce xml. Also I think when we we are just talking about directories, I might as well go build them all out now __,_,_ Thank You Dan Vega
Re: [flexcoders] File Explorer
So I am working with the file explorer and I came across another problem.
Server side I am writing out the following xml
root
node label=Root Directory
node label=bin path=H:\JRun4\bin isBranch=false/
node label=docs path=H:\JRun4\docs isBranch=true/
node label=jnbridge path=H:\JRun4\jnbridge isBranch=true/
node label=jre path=H:\JRun4\jre isBranch=true/
node label=lib path=H:\JRun4\lib isBranch=true/
node label=logs path=H:\JRun4\logs isBranch=false/
node label=servers path=H:\JRun4\servers isBranch=true/
node label=uninstall path=H:\JRun4\uninstall isBranch=true/
node label=verity path=H:\JRun4\verity isBranch=true/
/node
/root
__,_._,_
My 1st problem is when its an array collection I know how to get the 1st
item (getItemAt(0)) but here i have no idea how to tell the tree to expand.
private function buildTree(event:ResultEvent):void {
_treedata = new XML(event.result);
tree.expandChildrenOf(_treedata,true);
}
Also, now that I have my basic structure, i am not quite sure what the
approach is. Here i have a listener function so that when the folder is
opened we can make another trip the server.
private function onItemOpen(event:TreeEvent):void {
var path:String = event.it...@path;
//trip to the server.
}
** on that trip back to the server do I have a different function that re
writes my xml strucutre or am I just inserting the new xml block somewhere?
If I am just inserting how do I replace the block
node label=logs path=H:\JRun4\logs isBranch=false/
If anyone has an example of what I am doing please let me know.
Re: [flexcoders] Re: File Explorer
This is great stuff, thanks so much to all of you. For the record I am not arguing with anyone, I am just trying to learn the most efficient way of doing things. With that being said and a ton of screwing around with code I have come up with my solution (half way there). I have decided to only load the top level directories for a given path for speed purposes. I will start a new thread so that you can check out where i am Thanks to all! Dan
[flexcoders] Tree and array data
I am in the middle of building a file explorer and I have come to a
stumbling block. I have a simple screen that has a tree on the left and a
grid on the right. My ColdFusion components return an array and I end up
with something that looks like this. So far it works great but all of my
directories are showing up as leafs.
When I was messing around with the xml side I was able to provide an
attribute called isBranch. This gave the representation that there were sub
directories to this folder. The haschildren variable is letting me know if
this directory has any child dirs. How can I represent to the user that this
is a branch. After that I a pretty sure I can work through making another
call to the server and updating my array.
Thanks for the help in advance!

Re: [flexcoders] Re: Tree and array data
I think I am finally getting some where. In case you don't know what I have
been up to I will bring you up to speed. I am building a file explorer where
the left side will only be directories. When you select a directory the
contents (files) will show up in a datagrid on the right. I was having some
issue with display branches but I solved that by inserting an empty array on
any folder i knew had children.
Now I am trying to append the directories when the user starts drilling
down. So first I have an onItemOpen() method for when the folder is opened.
All this does is figure out the path and call my server side function that
will retrieve me a list of directories for a given path.
private function onItemOpen(event:TreeEvent):void {
var path:String = event.item.path;
FileManager.getDirectories(path);
}
I have a onResult method for the getDirectories() method called
listDirectories(). What I am doing here is
1. getting the list of directories.
2. if the tree data provider (_directorheies) is null we know this is the
base.
3. if not I am trying to figure out a way to append this array (or swap out)
with the children empty array i have as a placeholder.
Is this the right approach? I am obviously doing something wrong, hope
someone can point that out!
private function listDirectories(event:ResultEvent):void {
var dirs:Array = event.result as Array;
var parent:String = dirs[0].parent;
var pos:uint = -1;
// if the _directories array is null this is our root
request
if(_directories == null) {
_directories = dirs;
}else {
// we know the parent of the item that was clicked, find
the array position
for(var i in _directories){
if(_directories[i].path == parent){
pos = i;
break;
}
}
//if we found the position append the directories to the
children node
_directories[i].children = dirs;

[flexcoders] Tree problems
I am still having some tree / array issues that I am hoping to get some help
on. My tree loads an array of data that looks like this. Items with a
children array tell me that this folder should be a branch and it has
children. When you click on the branch I want to go retrieve the list of
directories for that folder and update the array with the new directory
data.
(Array)#0
[0] (Object)#1
lastModified = 1225560062218
name = bin
parent = H:\JRun4
path = H:\JRun4\bin
[1] (Object)#2
children = (Array)#3
lastModified = 1186192523437
name = docs
parent = H:\JRun4
path = H:\JRun4\docs
My itemOpen listener event basically get the path of the folder being opened
and fetch the directories for that path.
private function onItemOpen(event:TreeEvent):void {
var path:String = event.item.path;
holder = event.item.children;
FileManager.getDirectories(path);
}
When the list of directories is called this method is the result handler. IF
the tree data provider is null we know its top level. What I thought I could
do is setup a variable called holder that would the array object of the item
above. I thought this would pass the reference of that object and using that
reference i could set the new dirs into that empty array. This is not really
working so I was wondering if anyone has some ideas or what the right
approach should be.
private function listDirectories(event:ResultEvent):void {
var dirs:Array = event.result as Array;
// if the _directories array is null this is our root
request
if(_directories == null) {
_directories = dirs;
}else {
// what do we do now?
holder = dirs;

Re: [flexcoders] Tree problems
If you read through the post I am actually passed that and now trying to figure out how to dynamically insert / remove nodes. Dan
Re: [flexcoders] Tree problems
I am not sure what you mean by getChildren() though, when a branch is
clicked this method is called.
private function onItemOpen(event:TreeEvent):void {
var path:String = event.item.path;
FileManager.getDirectories(path);
}
The getDirectories() method of the remote object call has a result handler
called listDirectories(). So based on the path of the node that is clicked
(request for drill down) we make a remote call to get a list of directories
for that path. Im not sure between these 2 stpes how to add my new array of
directories to the empty children array of the node that was clicked.
private function listDirectories(event:ResultEvent):void {
var dirs:Array = event.result as Array;
// if the _directories array is null this is our root
request
if(_directories == null) {
_directories = dirs;
}else {
//?
}
}
hope that makes a little more sense.
Re: [flexcoders] Tree problems
The current target of the event is that, I don't think that will work?

Re: [flexcoders] Tree problems
Well i used that approach before and now I am back to using the same
approach. A placholder to that array works great but the problem I had
before is coming up again. when I click the folder no data shows up but the
data is in the array. If i close it and open it again it shows up. The tree
is just not updating for whatever reason. Is there something I need to do to
refresh everything?

Re: [flexcoders] Re: Tree problems
I would rather take that approach because there can be an infinite number of children and I want it to be fast. Thats why Ithink loading when requested is better for this scenario. How can I tell the tree to refresh its view? Thank You Dan Vega danv...@gmail.com http://www.danvega.org

Re: [flexcoders] Re: Tree problems
I appreciate the help! Does anyone have an example of this? I have a hard time believing that I am the first person to attempt something like this. For small sub directories it seems to be working fine but any large data set does not work, you need to close the node and then re open it.
Re: [flexcoders] Re: Tree problems
Ok, I think I found the solution but it was basically through guessing, can anyone tell me why I need both of these ? tree.invalidateList(); tree.invalidateDisplayList();
[flexcoders] Center a Popup window
I am trying to center a popup window that is being displayed from a tree. If you just call the static centerPopUp it centers it in the tree. When you add the popup though i noticed the second argument is the parent object. How can I get a reference to the stage itself so I can center this popup correctly. //add modal window PopUpManager.addPopUp(_renamedir,this,true); //center modal window PopUpManager.centerPopUp(_renamedir); Thank You Dan Vega danv...@gmail.com http://www.danvega.org

You could run the testIt method from anywhere (even from within an

[flexcoders] Custom Event Problem
For the file manager I am writing I am having an issue with dispatching a
custom event. I have a tree on the left with a custom tree item renderer. In
that renderer I have setup a context menu so the user can rename/remove/add
directories easily.
private function renameDirectory(event:ContextMenuEvent):void {
_renamedir = new RenameDirectory
_renamedir.oldDirectoryName = data.name;
_renamedir.parentPath = data.parent;
//add modal window
PopUpManager.addPopUp(_renamedir,DisplayObject(Application.application),true);
//center modal window
PopUpManager.centerPopUp(_renamedir);
}
My RenameDirectory component works well and does the renaming just fine. The
problem I am having is once the folder is renamed i need to refresh the tree
to show the changes. I figured for all of my options (add/remove/delete)
would just dispatch a custom event. Here is my RenameDirectory.mxml That is
dispatching my custom event.
?xml version=1.0 encoding=utf-8?
mx:TitleWindow xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute
title=Rename Directory width=300 height=125
showCloseButton=true creationComplete=centerWindow()

ro.renameDirectory(_old,_new);
ro.showBusyCursor = true;

closeWindow();
}
}

I think you make a great point but im just not sure how to do it. The data provider for the tree is not getting updated just yet. What I am doing is throwing a popup on the screen with what you want to rename the folder to. I do the renaming on the server side. Somehow I have to tell my main application to call the getDirectories() method again. I can do it from the view without really repeating a ton of stuff. Im just kind of stuck on how to make another call back to the server to list the dirs again. Thank You Dan Vega danv...@gmail.com http://www.danvega.org

[flexcoders] Custom Tree Item Renderer
I have a custom tree item renderer that is working out great except one
little small problem. In my item renderer I have some actions for adding /
removing / renaming directories. The only time I don't want the remove or
rename context menu items is when its the home directory. I know that I can
hack it and hard code it here because the data object is passed to each
function.
What I am trying to do though is going back to the main part of the
applicaiton (or pass in) the baseDirectory so I can account for change. Has
anyone got data in/or out of a renderer before? If it was just another class
it would be easy to put in the constructor but there is no constructor when
you add it to the tree.

Re: [flexcoders] Custom Tree Item Renderer
Thats exactly what I am looking for, a way to access public variables from

I am not exactly sure what you are trying to do. Are you trying to
test the data Item to see if it is the root node of the tree?
What is the dataProvider? If it is xml, you could test for parent() ==
null.
If it is nested collections then your connections would need to exponse a
parent poperty.
Of course, within an itemRender instance, as with any instance you can
access public members through the dom properties, like parentDocument, and
Application.application

*Subject:* [flexcoders] Custom Tree Item Renderer
I have a custom tree item renderer that is working out great except one
little small problem. In my item renderer I have some actions for adding /
removing / renaming directories. The only time I don't want the remove or
rename context menu items is when its the home directory. I know that I can
hack it and hard code it here because the data object is passed to each
function.
What I am trying to do though is going back to the main part of the
applicaiton (or pass in) the baseDirectory so I can account for change. Has
anyone got data in/or out of a renderer before? If it was just another class
it would be easy to put in the constructor but there is no constructor when
you add it to the tree.
itemRenderer=com.rocketfm.CustomTreeItemRenderer
package com.rocketfm {
import flash.display.DisplayObject;

add.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT,addDirectory);

menu.hideBuiltInItems();

this.contextMenu = menu;
}
private function addDirectory(event:ContextMenuEvent):void {
addWin = new AddDirectory();
addWin.dirPath = data.path;
addWin.parentPath = data.parent;
addWin.item = data;
// add window
PopUpManager.addPopUp(addWin,DisplayObject(Application.application),true);
}

Tracy you are genius! :) Are there cases like this where you just need to do this or is it bad practice? Thank You Dan Vega danv...@gmail.com http://www.danvega.org
[flexcoders] Loading Images Using CSS
I was looking through the archives and I came to what I thought was an
answer to my problem but I can't get it to work. I have logo / icon sets
that I want to be able to switch between. All of the sets have there own
style sheets and its working great for the buttons but i am having an issue
with the logo. There is no way to define a css image but I read that you can
do something like this
*main.mxml*
mx:Image id=logo initialize=logo.source =
StyleManager.getStyleDeclaration('logo').getStyle('source')/
*stylesheet
*.logo {
source: assets/images/robp/rocketfm_logosmall.png;
}
I tried this and got the following error. I am sure I am probably just doing
something wrong, anyone know what it is?
TypeError: Error #1009: Cannot access a property or method of a null object
reference.

[flexcoders] Loading images using binary data
I have a data grid that lists the contents of a folder an the server.What I
want to do is have a button that allows the user to swap between a data grid
and a list of thumbnails. There maybe a chance that these directories have
more than images but for now lets just pretend they are all images.
Using a remote object call I can go to the server and get the binary data
for an image, like I have in the example below. I was wondering if anyone
has an example of this in an item renderer and second once I grab the binary
data, how can I create thumbnails of that image?
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=vertical
creationComplete=init()
mx:Script
![CDATA[
import mx.rpc.events.ResultEvent;
private var imgData:ByteArray;
private function init():void {
var imgData = new ByteArray();
ImageService.readImage(C:\\dan\\rocket_step7_a.png);
}
private function onReadImage(event:ResultEvent):void {
imgData = event.result as ByteArray;
var loader:Loader = new Loader();
loader.loadBytes(imgData);
imageCanvas.rawChildren.addChild( loader );
}
]]
/mx:Script
mx:RemoteObject id=ImageService destination=ColdFusion
source=ImageLoader.src.ImageService showBusyCursor=true
mx:method name=readImage result=onReadImage(event)/
/mx:RemoteObject
mx:Canvas id=imageCanvas width=100 height=100/
/mx:Application

Re: [flexcoders] Loading images using binary data
I am able to read in images via the server returning the binary data of the image. My question is can I then create a thumbnail or should I be doing that on the server as well? Thank You Dan Vega danv...@gmail.com http://www.danvega.org
