[flexcoders] flex toggle button question
Hi All, I have a toggle button (play / pause), that needs to be 'clicked' externally from flash (e.g. a javascript call thru external interface to pause the video). I am able to make the button switch state by saying playPauseButton.selected=true This succeeds in toggling the skin for the button, but doesn't seem to toggle the internal state of the button. So the next time the button is clicked with the mouse, the click action doesn't fire, and you have to click the button twice to have it work. Has anyone seen this before? Thanks, Adrian

[flexcoders] Manipulate y-axis of built-in tooltip?
Hi all,
Quick question...is there a way to manipulate the y-axis position of
a tooltip without using a custom tooltip? For example, I have an image
that has uses the builtin tooltip and I need to have it display above
the image.
I have a series of images, side by side, in the bottom right of my
screen...when a user hovers over one of the images, because they are
already grounded in the bottom right, the tooltip shows up and covers
the images so the user has to really pay attention to the text to
realize which image they are clicking.
mx:Image id=cascadePic source={cascadeBtn} buttonMode=true
click=cascadeWindows() verticalCenter=0 right=70 toolTip=Click to
rearrange your widgets staggered one on another. /
I'm trying to see if there is an easy way to deal with this without
having to dig into custom tooltips.
Appreciate the help!

This is causing me problems with continuing to send messages to the application to continue panning. I am hoping the joystick will behave differently, but am also looking for any other suggestions. I have considered using a timer to send repeated increments (the back-end app only needs position deltas), but I haven't figured out how to stop that.

I just wrote up a simple C# web service that accepts an ArrayList:
[WebMethod]
public bool ArrayListTest( System.Collectio ns.ArrayList a)
{ ... }
Then in Flex I wrote this,
mx:Script
![CDATA[
import mx.collections. ArrayCollection;
private function sendWebServiceCall( ):void
{
trace(appComplete );
ws.ArrayListTest( new ArrayCollection( [ {name:bob, id:808 }, {

mx:operation name=ArrayListTest result=trace( event.result)
fault=trace( event.fault. faultString) /
/mx:WebService
When sendWebServiceCall is triggered, it calls the C# web service and
passes the ArrayCollection to it.
In the web service, the ArrayCollection is received as an array list
of XmlNodes. Each XmlNode contains a node for each field, even if it
is an empty string.
tns:id xmlns:tns=http://tempuri. org/808/tns:id

You mentioned you'd map the XML to typed objects in .NET.� How can I do
this?
As you're using a dataset, this isn't really an option. A dataset as
opposed to a collection of typed objects are two ways of handling data
from data sources; it is arguable which way is better.
The problem in your case, is that the XML generated as a result of
passing an ArrayCollection to a web service method cannot be passed
into the dataset's readXml method. (Even if it could by inferring a
schema, it would be different to your database's schema.)
The only way I know of to do seamless transfer of data without having
to parse XML is to use WebORB. Otherwise you will have to parse the
XML produced on both sides to re-create the dataset/object.
Instead of using arraycollection as dataprovider in my datagrid, can I use
another which would be much easier when I pass back to the .NET function?
I wonder if it is possible to bind your datagrid directly to the e4x
XML? That way you can pass the entire XML doc back to .NET via the web
service, and hence you can re-create the dataset using
dataset.readXML.

Once your project is created, choose the Data menu Item and then Create Application from Database. Create a connection to your database, choose a table, etc. I've been known to use the generated code just as a starting point to save time and then to modify it drastically. I don't think that the code generated this way is great but it's a decent way to learn how the code works. The web service calls should return array collections, not tables and the generated code on the flex side re-loads the tables every time that you make a change, including sorts so requires some tweeks and it's bloody slow.

Re: [flexcoders] Flex and .NET
Hi there...
We have a rather large RIA using C#.Net as the backend...and we have
a large number of arrayCollections and dataGrids/advancedDataGrids
We don't massage any of the data that we are passing with our web
services...we literally pass as as it's created...i.e. as an Array or as
a Object...
For example, we may have an AdvancedDataGridthat is asking for data
from our web service...in our .net code we'd simply have something like:
public ListMainClass BuildTheArray(string Group, string Admin)
{
ListMainClass configs = new ListMainClass();
SqlParameters[] sqlParams = new SqlParameters[2];
sqlParams[0] = new SqlParameter(@Group, Group);
sqlParams[1] = new SqlParameter(@Admin, Admin);
try
{
using (SqlDataReader dr =
(SqlDataReader)DB.Instance().ExecuteReader(main_stored_procedure,
sqlParams))
{
while (dr != null dr.Read())
{
configs.Add(new MainClass(
Convert.ToString(dr[Name]),
Convert.ToString(dr[Email]),
etc...
}
}
}
return configs;
}
Then in our Flex webservice def, we are defining the result as
Object (which I've seen a number of folks sugges E4X, but I've not
delved into the pros/cons of this).
mx:operation name=GetConfigs resultFormat=object
result=getConfigsResult(event) /
Now, since it's an object, in our web service result handler, you
can cast it a number of ways, but for the list as created above on the
.net side and since we are putting this data in an AdvancedDataGrid, we
simply say:
private function getConfigsResult(event:ResultEvent):void
{
configs = event.result as ArrayCollection;
ourDataGrid.dataProvider = configs;
}
Generally speaking, out of the 100+ web service calls we have, any
that return any kind of dataset we cast directly as an Array,
ArrayCollection or Object.
Now that said, we have seen something that is aggravating...with
large datasets, we see a lag in the transport time over our web
service. For example, we have a data set that returns 5000 rows of 125
columns of data...our T-SQL stored proc generates the data set in 6
seconds or less but then it still takes anywhere from 45s to 1.5m to
transport that dataset to the client side...and that's over a fast
connection...then, once it's in the client side, depending on how much
custom rendering we are doing, it takes up to 10-15 sec's to render the
data. So we have a bottleneck in our web service that causes a lengthy
delay on large data setswe are still researching on why this is
happening and the fix but just wanted to let you know as a heads up.

advantages are probably negligible.
Are you transmitting everything in the array collection back to the
web service, or just the IDs of the selected rows? Transferring
everything including the row data would remove the need for another
database hit, but for large datasets, that could be quite a bit of
traffic. I'd say it would be better just to transmit the IDs back to
the webservice, and let the webservice hit the database for the row
data (some caching on the server-side would help too).

Hi Sam,
Thanks for your reply.
As of now, I actually prefer to utilize what I know on .NET and what
I am
learning on Flex. Adding another utility (Web Orb) in my learning
process
may complicate things a bit. I might consult this later if I feel
that the
needs for is getting tremendous.
Anyway, I am actually able to generate the report from what I am
currently
doing (no error encountered), where the ArrayCollection I am parsing
into a
delimited string, passing the string to the webservice call, and
letting the
webservice de-serialize the string to populate a Crystal report document
which I subsequentlt display in another browser window which I call
from the
Flex application.
I mentioned that I did not feel it is the BEST way because I am
literally
storing all datagrid (report) information in a string variable.
Assuming
for example that the data displayed in the datagrid is quite huge, then
creating the delimited string would take some time and additional
processing
time could also be consumbed by the back end web service to parse
the string
and populate the report.
As of now, this is what the application does.

provider.
Memory usage with 10k row - 220 MB
Memory usage after removing all item - STILL 220 MB
Is this the standard behavior of datGird or do i need to apply some
workaround to get rid of this ?

Re: [flexcoders] Problem loading signed RSL
Hi Denis, If you've compiled using the RSL instead of merged code, you will need to locate the framework file (in your case: framework_3.2.03958.swf) on the computer used to compile and push that file to your web server along with your application swf's...when you use the RSL's and make any changes after the fact, that framework file adds digest entries that have to be available to your app on the server. We had this problem quite a bit and it took awhile to figure out that this was the issue. Now, whenever we push our code to our server, we make sure to push the framework file as well and we haven't had the problem since. HTH, -adrian Denis wrote: Hi all, I am trying to publish an app with the signed framework RSL. The application works fine when accessed online from my machine (developer).

Re: [flexcoders] Links in Flex Data Grid Collumns
You need to take a look at setting up a custom item renderer for the dg column. As for an example, try searching flex datagrid itemRenderer to get a good start. in a nutshell, you create your itemRenderer as a separate component then reference that component in your DG column...such as: mx:DataGridColumn itemRenderer=rendererdirectory.URLRenderer/ we generally use this for hyperlinking email addys and it works great. Our actual renderer is based on a Label and we override the set data function, passing our dataItem into htmlText with the url info and then we return the renderer. We have a click listener on the Label declaration that (in the end) fires a navigateToURL() function. Good luck! Adrian guess what wrote: I have a Flex Data Grid Populated from XML .

Back in older versions of Flash the only way to communicate between the browser and the ActiveX was to use things like setVariable then inside Flash you would have a watch expression that watched for changes to that variable, and reacted. The variable value could only be a string (I think). Back then we would change the value of the variable from outside, have Flash react to the change, reset the value of the variable to its non-set state. Assuming this would still work, when the .NET application regained focus you would tell the ActiveX instance to setVariable( focusReceived , true); and in Flash it would see that, reset the listeners. One word of warning, if your resetting your listeners constantly, are you doing anything to remove the old listeners first - if not that may well be the source of your memory leak. I used the setVariable method in VB with the old Flash active x controls a number of years ago and it worked flawlessly, you just have to set it up right to begin with and it was obviously messier then the ExternalInterface method.

[flexcoders] Re: Datagrid question
There are a few ways to do this but the easiest is to add a value to your
object that will be updated in the item renderer, perhaps in the set data
function. You could also use an event and a public property in your item
renderer.
var myObject = new myClass();
override public function set data(value:Object):void
{
//value is the object from your list
myObject = value as MyClass;
}
private function buttonClick()
{
myObject.randomNumber = MyRandomNumberGen();
}
You should now be able to access randomNumber in your application.
This will require you to parse your ArrayCollection into an object.

Thanks for responding, Tracy.
Let's say this is an application that allows generation of license numbers.
Imagine this:
You have 3 columns in the datagrid. The first and second columns are the
first and last names of a person. The third column is a button (which is
really part of an MXML component) that has it's 'label' set as Click to
generate license number. When the user clicks the button, the logic to
generate the license number is within the component and will be output to
the label property of the button, and the button will no longer be
clickable. The application allows multiple people to be listed in the
datagrid. Outside the datagrid, there is a button that says Click to print
all.
Given the specs I described so far, it's clear that I have to be able to
iterate through each row in the datagrid, extracting the data from each
column of each row. Typically, I would just get the dataProvider array
collection object, and the problem would be solved. But because the license
number is being output through the label property of the button (which is
part of a MXML component) and is not part of the original dataProvider data,
I can't go that route.
I figured I now have to somehow iterate through each row, grabbing the data
of each column of the row and storing it somehow. Is there a way for me to
get the license number from the label property of the buttons?

Re: [flexcoders] ADG Memory leak.

We have a fairly large ADG (100+ columns) and every time we'd scroll right to see more columns, more renderers would be created in addition to the one's already present...and scrolling back left would recreate them again instead of using the one's that had already been created...at one point, we had several hundred instances of renderers running for a single grid. Insanity! And, because the ADG and the DG are maintained by two separate teams at Adobe, one is not related to the other and in this case, the DG does not have the same leaks as the ADG. In the end, we had to write a serious piece of code to manage our renderers, which finally rid us of the leaks we were encountering. I've been working on trying to encapsulate our logic so I can post it here as I know a lot of other folks have run into the same problems and could probably use the help. Best, Adrian Wesley Acheson wrote: I've wasted most of the day trying to figure out why my application was leaking memory. I was dynamically adding and removing columns from the AdvancedDataGrid. I noticed that it was slowing down a lot. I naturally assumed that it was my custom item renderer and even after reading Alex's blog entry about using the profiler I couldn't figure out what was holding references to my item renderer. Anyway the error continued to happen after I commented out all the code in my item renderer. I even changed it to subclass AdvancedDataGridItemRenderer, still no joy. So I removed the custom item renderer and noticed that instead of my ItemRenderer the ADG didn't remove references to its own item renderer. Anyway I changed to a standard DataGrid and all worked correctly. The references were removed when garbage collection occurred I had to change my code a bit. This isn't really a question more of a complaint really. I don't know if it was my code or just a problem with the ADG though I suspect the latter. A couple of things I noticed with the standard DG. Firstly if setting the itemrenderer on the DG itself it also uses the same ItemRenderer on the header rows. Is this correct behaviour. Setting the ItemRenderer on the column seems to keep the normal header renderer. This I admit has me confused is this the way its supposed to work? How would I set all the cells to a custom IR and leave the headers alone? It seems inconsistent. I have read the excellent Articles on Alex's blog. Anyway that's all. Regards, Wes
Re: [flexcoders] calling a function from swf
This is pretty straightforward. We do a lot of this in our dashboard app
where we have a function called registerSWF(). This helps us keep tabs
on all the swf objects that are loaded on the dash.
private var registeredSWF:ArrayCollection = new
ArrayCollection();
public function registerSWF(swf:Object):void
{
registeredSWF.addItem(swf);
}
Each child swf calls this functions when they load:
application.registerSWF(this);
Then, when we need to access a function from within the child swf, we
pull it from the AC (so we can reference it) and directly call the function:
for each (var swf:Object in registeredSWF)
{
swf.someFunction(vars);
}
Keep in mind that the function in your child swf must be in the public
scope or the parent app cannot see it.

Re: [flexcoders] Converting strings to numbers before sorting?
Hi Keith,
Have you tried casting your string to a number via the number()

problem sorting kit numbers in true numerical fashion as we can have
some that begin with a letter versus a true number. So in our sort
compare we do this:
public static function compareKitNumbers(obj1:Object,
obj2:Object):int
{
var value1:Number = (obj1.KitNum == '' || obj1.KitNum ==
null) ? null : new Number(obj1.KitNum);
var value2:Number = (obj2.KitNum == '' || obj2.KitNum ==
null) ? null : new Number(obj2.KitNum);
var kitnum1:String = obj1.KitNum as String;
var kitnum2:String = obj2.KitNum as String;
var kit1Length:int = kitnum1.length - 1;
var kit2Length:int = kitnum2.length - 1;
if (isNaN(value1) isNaN(value2))
{
if (kitnum1.substr(0,1) kitnum2.substr(0,1))
{
return -1;
}
else if (kitnum1.substr(0,1) kitnum2.substr(0,1))
{
return 1;
}
else
{
value1 = new Number(kitnum1.substr(1,kit1Length));
value2 = new Number(kitnum2.substr(1,kit2Length));
}
}
if (value1 value2 || (isNaN(value2) !isNaN(value1)))
{
return -1;
}
else if (value1 value2 || (isNaN(value1) !isNaN(value2)))
{
return 1;

Hi all,
I have a problem related to sorting type-casted numeric data, and was
wondering if someone could help me out:
Given some numeric data stored as strings (11.5), how can I populate
it into a DataGrid and have it sort properly?
From the Flex API docs
http://livedocs.adobe.com/flex/3/langref/mx/controls/dataGridClasses/DataGridColumn.html#sortCompareFunction
it appears that when you use a labelFunction instead of a dataField to
specify what should be displayed in a column, that the output of the
label function is what is then used for sorting:
If you specify a value of the |labelFunction| property, you must
also provide a function to the |sortCompareFunction| property,
unless sorting is not allowed on this column.
So my first attempt was to simply cast the strings to numbers within
the label function and hope that the default sorters would still be
available:
private function testLabel2(item:Object, col:DataGridColumn):Number {
return parseFloat(item.string);
}
... I also tried using Number(item.string), however, neither worked
so I went to manually specifying the sort compare function:
public function sortAsIs(obj1:Object, obj2:Object):int {
if (obj1 obj2)
return -1;
else if (obj1 == obj2)
return 0;
else
return 1;
}
This didn't do the trick either. So finally, I decided to try doing
the conversion in the sortCompareFunction, just in case it was
comparing the original data fields and not the output of the label
function. Again no luck.
Anyone have any suggestions? Any help would be greatly appreciated.
Here is the full code for the test case I am describing:

[flexcoders] swfLoaded charts dataTips lose parent container boundaries -- WAS: 3.0.2 Upgrade Causes PieChart dataTipFunction placement to go haywire???
OK, after a half day of waste on this, I've narrowed down the problem
that I am having with my pie chart dataTips.
It seem most likely that the problem exists somewhere in changes that
were made to the swfLoader code between v3.0 and v3.2. When I have my
charts loaded via a swfLoader into a panel on my dashboard, my
dataPoints go grape ape on me and instead of keeping their positioning
within the panel, they default to the parent container and get way ugly.
When I hard code the same charts from the swf to the dashboard code, the
dataTips function perfectly.
I have attached two files here. The first (chartTesters.mxml) is a basic
layout with two panels on a cavas. One panel and piechart set has been
created in the mxml. This works beautifully. You will also see a
second panel setup dynamicaly in the AS code, creating the panel and
calling the swfLoader to load the swf created from the second file
attached here (testHGWidget.mxml). It is the same code as the pie
charts in the mxml. This one's dataTips are jacked.
When you run it, you will notice that hovering over the pie wedges on
the Static/Hardcoded charts provide dataTips just above and to the right
of the mousewhere they should be.
When you hover over the pie wedges on the Dynamic/swfLoaded charts, your
dataTips are forced to the top left of the main canvas instead of
staying within the panel.
Any help with this would be GREATLY appreciated as I really need to fix
this and am suspecting it is an Adobe bug.
Best,
Adrian

[flexcoders] Wicked Memory Leaks and Massive Loitering Objects
Hi all, My forehead is becoming flatter by the minute as I bang my head against the wall on this one In my dashboard application, I have a tab navigator with a canvas that defines each tab. A single tab/canvas has numerous panels and each panel has a swfloader swf file. When a user clicks on a different tab, I'm trying to unload all the components on the tab (canvas.removeAll()) before making the switch...in an effort to free up the memoryI've made sure to go thru and add appropriate listener removals but when I run the app, I end up like an ant standing in front of Hoover dam, yelling Bring it on!!. After clicking the third tab, memory is maxed and FF crashes So, I've run this sucker through the flex profilertaken snapshots and compared to find loitering objects...holy crapthere are PAGES of loitering objects...with the top two offenders being 62,000 String instances taking up 3,233,462 (30.01%) of memory and 439 Class instances taking up 3,308,623 (30.71%) of memory. Upon investigation, every freakin string that is returned from my web service calls and used in the panels is saved in memory... The rest of the top ten list are: UITextField, Function, Object, Array, Button, QName, WSDLMessagePart and UIComponent. (wtf is QName???) I've poured thru what I can find on the net about getting rid of all this junk...and haven't found much. I'm seriously hoping for some help because we cannot go public beta with this until I get the memory problems ironed out. I found some information that is perplexing... 1.) The removeAll() doesn't actually unload anything from memory?? It only removes it from the container?? What!?! 2.) I scrapped the removeAll() and tried instead to use the delete() function, cycling thru all the panels on the canvas and doing a delete panel. That pukes on me with the error 1189: Attempt to delete the fixed property mdiwindow. Only dynamically defined properties can be deleted. 3.) It seems that renderer's like to hang out for a while and enjoy the show...with no clear way to get rid of them (kinda like my Uncle Jesse) So, folks, all help here would certainly be appreciatedhow in the world do I get this stuff cleared out? Should I be trying to unload the swf's or will that results in the same thing as the removeAll()...gone...but not really? Looking forward to getting this resolved, Adrian
Re: [flexcoders] Is there any way to use predefined functions for a sortCompareFunction?
I don't think you can use the sortCompareFunction that way...it needs a
function to process your data against.
We use a number of customized sorting functions on a number of our
fields via both sort.compareFunction as well as adg.sortCompareFunction,
though funny enough, the compareFunction is a bit different depending on
which way you are using it. If you are tying it to an ADG
sortCompareFunction, it takes two arguments while when using a Sort()
compareFunction, it takes three.
When trying to do an alphabetical sort (on the ADG), we do this:
public static function compareLastNames(name1:Object,
name2:Object):int
{
var newName1:String = name1.LastName + name1.FirstName +
name1.MiddleName;
var newName2:String = name2.LastName + name2.FirstName +
name2.MiddleName;
if (newName1.toLowerCase() newName2.toLowerCase())
{
return -1;
}
else if (newName1.toLowerCase() newName2.toLowerCase())
{
return 1;
}
else
{
return 0;
}
}
and when using a Sort() we do the very same logic but we have to add a
fields parameter into the method signature:
public static function compareLastNamesWithFields(name1:Object,
name2:Object, fields:Array = null):int
In this case, we've automatically set the fields array to null as we
never have any fields to pass in but without it, flex throws errors
(we've long thought this to be a bug).
Also note that these are public and static because we've abstracted them
into a class.
Hope this helps!

You are misunderstanding how listeners work. You add the listener to
the component that **dispatches** the event, and have it call a method
where you want the action to take place.
parent just goes up one component. The surest way to do this is to
use Application.application.addEventListener().
A bubbling event will hot help you going in this direction (down to
the child)

Hi Steve,
But I need the child swf to react, not the parent. So I think the

[flexcoders] How to reload a SWFLoader swf in place
Hi All, Have our dashboard application with numerous widgets (individual panels with a swf loaded with via a SWFLoader. We have a scenario (or six) where a user may change data in one widget that needs to be reflected in another widget. Short of making them completely reload the app just to see the one widget get updated, I've added a reload icon to the panel controls, thinking that they can reload the single widget at will. So now the key questions are these: 1.) How do I get a SWFLoader object to reload in place? 2.) How do I get the document.parameters that were passed when the original SWFLoader was created passed again into the reloaded swf? Thanks in advance!! Adrian
Re: [flexcoders] What comes out of a datagrid
Hi Wally, We have something that's practically identical to what you have described. For ours, instead of waiting until all the people have been dragged, we setup a number of listeners on our blank ADG (DRAG_START, DRAG_ENTER, DRAG_DROP) and as soon as the person is dropped, we reference our sourceGrid.selectedItems property which has the pertinent information about the 'fella' that was droppedonce we have that, we hit our web service, passing the information, including the group change info to our db. Alternatively, you can take a look at your teamDG.dataProvider and see the data that's been dropped in it... HTH, Adrian Wally Kolcz wrote: Lets say I have 2 DataGrids, one has user info in it (populated with a binded ArrayCollection) and the other is blank (lets call it id=teamDG). You can drag the people from the populated to the blank to populate it. Got that part to work fine. When you have dragged all the people you wanted to the blank one and then wanted to save that new group of people, how can you go about saving them? Is there a specific array or object associated with that DataGrid (teamDG) which then you can pass to a function to populate a database? Any examples or tutorials out there? Thanks.
Re: [flexcoders] Re: Default sorting for Datagrid
We handle this in a couple different fashions...for data already in the grid, (albeit for an ADG vs. a DG), by setting up a custom sorter. var sorter:Sort = new Sort(); sorter.compareFunction = sortKitNums; sorter.fields = new Array(); memberReportData.sort = sorter; memberReportData.refresh(); In the code above, we instantiate our sorter and then point the compareFunction to our custom sort function. Then we invoke the sort against our arrayCollection, refresh, then do a validateNow on our ADG and poof! Usually, though, we also sort the data on the server before it ever gets to our flex layer. We are using a MS-SQL Db and via a ton of stored procedures, our data sets are ordered as we need them before they are returned to the flex...this way, we use the horsepower of the server vs. relying on the host machine. This would be easily done for you as well if you have a date field as the ORDER BY function of most DB languages will correctly sort your data by a date field. HTH, Adrian valdhor wrote: I don't know if this is overly helpful but I normally do my initial sort on the server (It is much easier for the database to do the sorting). If you really want to do the sort at Flex end you should sort the underlying dataprovider using the sort and sortfield classes.

[flexcoders] [Fwd: UPDATE: how to forcibly minimize a window via flexmdi window]
Ok,
So once my morning caffeine jolt hit me, I realized that I already
know how to force a mouseclick in the event:
newPanel.minimize(new MouseEvent(MouseEvent.CLICK, true, false));
So, I fire the event and even walked the code thru the debugger to
watch it go into the function and act normally...but my window still
defiantly sits un-minimizedsigh...

Hi gang,
I've been toying with the outstanding flexmdi component from flexlib
and have found something challenging...
One of the pieces of the MDIWindow is the minimize() function. I'm
creating the windows on the canvas dynamically based on the users last
know settings...including whether they have minimized any of the windows
on their dashboard. I have a variable in their record for each window
called isCollapsed (bit/bool). What I'm trying to do is when the
records are read and the windows are dynamically created, I check to see
if the isCollapsed == true and if so, I'm trying to fire the
MDIWindow.minimize() function. However, it's expecting a mouseEvent and
I'm not sure how to force a non-existent event into the function???
Basically, I need to programmatically emulate a mouseclick on the
minimize button of the window.
I've tried a number of alternative methods without success,
including these:
newWindow.minimize();
newWindow.minimize(null);
newWindow.dispatchEvent(MDIWindowEvent.MINIMIZE);
dispatchEvent(new
MDIWindowEvent(MDIWindowEvent.MINIMIZE, newWindow));
Here is the minimize function:
public function minimize(event:MouseEvent = null):void
{
// if the panel is floating, save its state
if(windowState == MDIWindowState.NORMAL)
{
savePanel();
}
dispatchEvent(new MDIWindowEvent(MDIWindowEvent.MINIMIZE,
this));
windowState = MDIWindowState.MINIMIZED;
showControls = false;
}
Has anyone tried to do this or have any ideas on what to try next?
Thanks,

Re: [flexcoders] Re: DataGrid Drop Deny based on dropIndex
Hi S,
That's a toughie...I haven't tried to selectively deny a drop
depending on an index...
I don't know of any methods that will reject the drag-drop other
than the stopPropagation and stopImmediatePropagation methods. You
might try looking the DRAG_OVER event to see if you can selectively
showDropFeedback and hideDropFeedback depending on what rows you are
over and then in your listener, if it's dropped where its not supposed
to be cancel the op. Another idea would be if you know which row's you
don't want drop enabled on, see if you can manipulate the drop
properties of those row to deny the drop??
Not really sure what else to do herebut am interested to know if
you find out how!
Best,
Adrian
park96 wrote:
Hi Adrian,
Thanks for the response. So I didn't know about the hideDropFeedback
method on the ListBase class. That helps a bit but the problem I'm
encountering now, is that when I start dragging, it denies it at
first, but once it passed over a row that it's able to drop, it
becomes droppable over all the rows. It looks like the
DragManager.acceptDragDrop() toggles on and won't turn back off even
if I hide the dragDropFeedback. Is there a method like
DragManager.rejectDragDrop() so that when I'm dragging a row over all
the rows, that it will reject certain rows, but accepts others?
Thanks

Re: [flexcoders] adding components in alert control
The only way I have seen this possible is to use the PopUpManager.
For our app, a user can delete a participant from their group (by
dragging their ADG row to a trash can), but have to provide a reason
why. So, we created a TitleWindow component that we pull in via the
PopUpManager. Here's the code. I imagine there is a better way to do
this, but this is what works for us.
The component (called DeleteParticipantTitleWindow.mxml):
?xml version=1.0?
mx:TitleWindow xmlns:mx=http://www.adobe.com/2006/mxml;
showCloseButton=true
width=350 height=100%
borderAlpha=1
verticalAlign=middle horizontalAlign=center
mx:Script
![CDATA[
import mx.managers.PopUpManager;
]]
/mx:Script
mx:Text text=Please enter a reason for removing this participant:/
mx:TextInput id=reason width=300/
mx:HBox
mx:Button id=okButton label=OK/
mx:Button id=cancelButton label=Cancel/
/mx:HBox
/mx:TitleWindow
Then we reference it in our code like this:
First, we alert them (using our custom alert which extends the standard
alert class) that their delete is permanent:
private function deleteParticipantDrop(event:DragEvent):void
{
var component:IUIComponent =
IUIComponent(event.currentTarget);
dragComponent = component;
DragManager.acceptDragDrop(component);
isEditingParticipantInfo = false;
isDeletingParticipant = true;
deleteParticipantDropEvent = event;
event.stopImmediatePropagation();
alert.confirm(Are you sure you want to delete this
participant from the project? This cannot be reversed!! An email will
be +
sent to notify this participant and you will
receive a copy of it for your records., confirmRemoveParticipant);
}
Then, on confirmation, we popup a window where they have to provide the
reason for delete (the key here is the deleteReason = ... in the third
line of the conditional):
private function confirmRemoveParticipant(event:CloseEvent):void
{
if (event.detail == Alert.YES)
{
deleteParticipantDropEvent.action =
DragEvent.DRAG_COMPLETE;
dispatchEvent(deleteParticipantDropEvent);
deleteReason =
DeleteParticipantTitleWindow(PopUpManager.createPopUp( this,
DeleteParticipantTitleWindow , true));
PopUpManager.centerPopUp(deleteReason);
deleteReason.showCloseButton = true;
deleteReason.title = Reason for removal from project;
deleteReason.addEventListener(close,
cleanupRemoveParticipant);
deleteReason[cancelButton].addEventListener(click,
cleanupRemoveParticipant);
deleteReason[okButton].addEventListener(click,
finalizeDeleteParticipant);
isDeletingParticipant = false;
}
else
{
cleanupRemoveParticipant();
}
}
Then, once they enter ok, we validate their text entry and continue
with the delete, which I've removed all that code for this, but wanted
to show how to access the text field from the popup.
public function finalizeDeleteParticipant(event:Event):void
{
if (deleteReason.reason.text != null)
{
memberReportData.removeItemAt(memberRpt.selectedIndex);
}
else
{
alert.info(You must provide a reason for removing a
participant from your project!!);
}
cleanupRemoveParticipant();
}
Hope this helps!

Hello guys,
I'm trying to filter my ADG without success :
I created a GroupingCollection from a flat ArrayCollection.
ADG's dataProvider is GroupingCollection.
First issue : refresh
if I filter the underlaying ArrayCollection, the related
groupingCollection doesn't refresh automatically (bug? feature?)
Actually I menaged to force gc.refresh() with some event( it is
impossible to listen on CollectionEventKind.REFRESH because of
infinite loop ac.refresh = gc.refresh )
Second issue (more important) : openNodes
Ok now that my gc is refreshed, the Tree in the ADG collapses
itself
(ok let say that is normal), and I need it to expand all nodes
that
were opened before.
I tried to do something like this :
var openNodes : Object = IHierarchicalCollectionView(
myADG.dataProvider ).openNodes;
gc.refresh();
myADG.dataProvider.openNodes = openNodes;
and it doesn't works.
next I tried this :
var openNodes : Object = IHierarchicalCollectionView(
myADG.dataProvider ).openNodes;
for each( var node : Object in openNodes )
{
IHierarchicalCollectionView( myADG.dataProvider.openNode( node )
}
guess what, doesn't work :)
I'm calling myADG.invalidateList() each time too.
I don't know what to do to achieve this simple task, I'm a bit
disappointed because I expected lot more from the brand new
AdvancedDataGrid and this basic functionality actually seems too
hard
to implement.
I still hope I'm wrong and someone can show me the correct
solution :)
Thank you all,

I have a dashboard application (dashboard.swf) that uses multiple swfloaders to load the various widgets that the user needs (which are also .swf's). The trick is that I need to pass a variable into the widgets to let them know which user logged in which allows the widget to load the data specific to that user. I've seen a method that utilizes a localConnection to pass a connection string, a method and parameters...my concern is the local connection...there can be up to 20 widgets on a dashboard and opening an LC for each doesn't seem like it's be efficient... Help?! Thanks, Adrian
Re: [flexcoders] Passing variables from .swf to .swf
Hi Tracy, We are already using a cental db here...we are running a pretty massive DB via SQL, use C#.Net for our control layer and use Flex/AS for our presentation, which calls for the data using a WSDL...the dashboard is for project managers...when they login to the dashboard, I need to be able to pass their loginId to the widgets so they can load the various data points for the project that person manages...i.e. widget-A loads project statistics...and it needs to know which project's statistics to load...the only way it will know that is by having the userId that logged in. Or am I not understanding what you are referring to as a central data model? Adrian Tracy Spratt wrote: How about just having a central data model?

Re: [flexcoders] Passing variables from .swf to .swf
Hi Tracy,
Oh if only it were that easy!! Looks like it's gonna have to be much
deeperhere's why...
A project manager can have any number of projects they run...
The dashboard is setup so they have access to all their projects via
one dashboard
Basically, when they login, I get a list of all the projects they
manageand then create a simple viewStack with tabNavigator, one tab
for each of the projects they run. Each tab has the same widgets, only
loaded with the data specific to the project for the tab they are
looking at (much akin to having several tabs opened in Firefox, all of
them on Amazon, yet on each one, I'm looking for a book different from
the other tabs.)
The widgets are simple stand-alone apps that are repatedly used in
each tab...i.e. projectStatistics.swf is used once on every tab (i.e.
for every project) on the dashboard. For each instance of the widget,
it needs to know the project name so it can query the data for that
specific project.
All of this is created dynamically in my actionscript (will paste
below). In addition, the user can customize (and persist in the db)
their widget configuration for each project (tab). So, with my 3-column
layout, they might have, on [Tab1] Project 1, column 1, Widgets A, C
and D while on [Tab2] Project 2, column 1, Widgets A, B, F, Q. All of
this persistence is read from the database upon their login and the code
simply builds their dashboard, tabs and widgets based on their last know
setup.
Since this is so dynamic, I don't think I can get away with trying
to access any static public variables via application.application. I've
taken a look at your example on cflex.net on manipulating the .content
property, but it looks like I need to specifically reference each of the
loaded widgets, which is not very simple considering their dynamic
loading...
Any other ideas? And I cannot seem to find much regarding the data
model in flex you mentioned...
Best,
Adrian

[flexcoders] DandD of row to last row of last node in grouped ADG throws RTE...looks like Adobe Bug to me...thoughts?
All, I have an ADG that contains a grouped collection. In the dataset, there are 21 nodes...each node has 1 to many children. When I attempt to drag a row, either from another node or within the last node, and drop it below the last item in the last node(i.e. make it the very last row in the group and ADG overall), the systems treats it like I'm trying to drop it at the node level instead of the child level and throws an out of bounds (which is probably due to my code that persists the orders in the database). In watching it in debugger, here are the values that occur. Here's the setup: 21 groups (nodes) in the adg. The last group has 4 children (rows). If I expand only the last node...and drag the first row of that node to the next to last row, the adg.dropData.index == 3 and the adg.dropData.parent == the node object that I am in, which is should because I am dropping it within that grouping. If I drag the first row of that node to just below the last row, intending on making it last in the group, the adg.dropData.index == 25 and the adg.dropData.parent == null. It obvious that the adg doesn't realize that I am dropping it within the last position of the group because it's the final row in the overall adg. So I tried to outsmart it. I created a handler to determine if the adg.dropData.index = (the hierarchical tree length + the length of the all the open nodes in the tree), using the assumption that if this is true, then the user is trying to put the row at the end (keep in mind I am also checking to make sure it's not a node that is being dragged to reorder). If this is true, then I manipulate the actual event.dragInitiator._dropData and the adg.dropData values and force the index (which I calculate from the number of children in the last node) and parent information into them. To a point, this works and my drop is persisted to my database per design. However, the dropped row disappears from the grid, only appearing in its correct position on refreshing the grid. The problem appears in the AdvancedDataGrid.as class.within the updateDropData function where calculations are being done to re-place the row...because the index value is 25, the top and bottom parent calculations seem to get all jacked up and in the end, the _dropData gets reset to the old values, completely overriding my efforts to cheat.

[flexcoders] Search Function within a Flex App -- Not Filter
Hi All, I have another wild one...has anyone seen or figured out how to embed a search function within a flex app? I have seen the information on creating filters but they all filter out (read: remove from visibility) all the data that falls outside the filter. In other words, I need to figure out how enable a search that acts the same as doing a 'find' in a webbrowser...a user enters a search criteria and the focus goes to any instance of that search criteria.

Otherwise, call the preventDefault() method, to prevent editing.

[flexcoders] Printing ADG - Livedocs code results in printing gray box
Hi all,
I posted this problem awhile back with no response and am going to
try again before I call Adobe. I've seen others with the same issue,
but no resolutions pending.
I have used the code from Adobe's labs website:
http://labs.adobe.com/wiki/index.php/Flex_3:Feature_Introductions:_Advanced_DataGrid
The problem is that when using this function, as written, and I try
to print my ADG, all that is output from the printer is a gray box. Has
anyone else found the solution to this one?
Here is the code:
private function doPrint():void
{
var printJob:FlexPrintJob = new FlexPrintJob(); //
Create an instance of the FlexPrintJob class.
var printADG:PrintAdvancedDataGrid = new
PrintAdvancedDataGrid(); // Initialize the PrintAdvancedDataGrid control.
if (printJob.start() == true)
{
printADG.includeInLayout = false; // Exclude the
PrintAdvancedDataGrid control from layout.
printADG.source = memberRpt; // Provide the data
source for the report
addChild(printADG); // Add the print-specific
control to the application.
printJob.addObject(printADG,
FlexPrintJobScaleType.MATCH_WIDTH); // Add the object to print. Scale it
to fit width of page.
printJob.send(); // Send the job to the printer.
removeChild(printADG); // Remove the print-specific

Re: [flexcoders] Disable Column reordering on Advanced Data Grid?
We had a similar challenge except we needed to persist to the DB the
rearrangement of columns...to do this, we extended the event class for
our listeners so we could capture column selection events...You might
try using the same thing and on column selected, perform a
preventDefault() which would halt any action from happening...
Here's the class:
package com.ftdna
{
import flash.events.Event;
public class ColumnSelectedEvent extends Event
{
public var colIdx:int;
public static const COLUMN_SELECTED:String = columnSelected;
public static const LABEL_SELECTED:String = labelSelected;
public static const COLUMN_DROP_TARGET:String = columnDropTarget;
public function ColumnSelectedEvent(type:String, colIdx:int)
{
super(type);
this.colIdx = colIdx;
}
override public function clone():Event
{
return new ColumnSelectedEvent(type, colIdx);
}
}
}
And here is an application of the class:
adg.addEventListener(ColumnSelectedEvent.COLUMN_SELECTED, denySelect)
private function denySelect(event:ColumnSelectedEvent):void
{
if (event.type == ColumnSelectedEvent.COLUMN_SELECTED)
event.preventDefault();
}

[flexcoders] Tricky one...adding attachments to an email generated from the app
Hi guys, And yet another one that I haven't seen... Part of our app allows a user to send an email to one or more folks in their view. We simply provide a state that has a simple email form they fill out and then we pass that information back through our web service (.NET) that actually has the procedure to send the email. What I need to be able to do is allow the user to add attachments to the email they want to send out. Is there any way to do this and is there a better method to the email solution? We briefly toyed with the idea of just creating the hyperlink to use their own email client, but a user can literally send a bulk email to several thousand people and a hyperlink would die a slow, miserable death trying to handle that.

Hi, Adrian,
Wow. That's a doozey of an issue. When you're on the bleeding edge,
you tend to bleed a lot. My recent experience with the ADG wasn't
pretty or pleasant, and I bled a lot. But by posting to this group and
various blogs, I found kind souls who helped and finally, through
trial-and-error, found the solution.
Some thoughts on the problem,
- Could it be that after the first (and each) delete, you might need
to refresh your dataprovider for the ADG? It might be worth a try.
- I know the myADG.invalidateDisplayList() helped a lot. It forced
the ADG to fetch the latest data. I overrode the set data() method in
the itemRenderer. No explicit validateDisplayList() method.
- I also used the myADG.invalidateList() elsewhere when the screen
wasn't refreshing.
As Alex Harui suggested, do a debug build and post the entire stack
trace with the linenumbers here. Good luck :)

Ok, I have spent the morning pouring through the debugging trying to
figure out what this error is and am completely stymied. I have been
able to determine it has nothing to do with my delete functions...the
code never makes it to them anyway...I suspect it may be a bug in the
core AdvancedDataGridBaseEx code. The actions that are being done are:
1.) A user drags a grouped node off the 6-column ADG to the trash can
image on the app control bar...
mx:Image source={trashImage} right=80
buttonMode=true
toolTip=drag a subgroup here to delete them from the project
dragDrop=deleteSubgroupDrop(event)
dragEnter=deleteSubgroupEnter(event) id=image2/
2.) my drag manager is listening and accepts the dragEnter:
private function deleteSubgroupEnter(evt:DragEvent):void
{
var obj:IUIComponent = IUIComponent(evt.currentTarget);
DragManager.acceptDragDrop(obj);
}
2.) and then accepts the dragDrop. On the drop, I am throwing an alert
box up to confirm that the user wants to do this:
private function deleteSubgroupDrop(event:DragEvent):void
{
partsToDelete = new Array;
partsToDelete = currentSubgroups.selectedItems;
subgroupToRemove =
currentSubgroups.selectedItem.GroupLabel;
alert.confirm(Are you sure you want to delete this
subgroup: ' + subgroupToRemove +
' from the project?? This cannot be reversed!!,
deleteSubgroupAction);
}
3.) When it hits the alert box, the code then jumps into the core to
render the alert box. The code eventually ends up in the
LayoutManager.as code on line 592, function validateDisplayList():void.
4.) The logic steps thru all of the objects that are on the stage and
for each of them calls the obj.validateDisplayList(); function. All
goes
well until it gets to my ADG. Via the validate leg, it goes to the
ADGBaseEx.as code to the function
commitEditedItemPosition(coord:Object):void. During the course of this
function, the columnIndex is manhandled all over the place.
Eventually,
it gets to line 4406 where it is checking:
if(colIndex lockedColumnCount)
and passes this check, stepping to the next line of
if (colIndex horizontalScrollPosition + lockedColumnCount)
which fails, then executing a loop against the colIndex. Once the
loop is completed, the final line
actualColIndex =
absoluteToVisibleColumnIndex(displayToAbsoluteColumnIndex(colIndex));
is called, which is on line 7164 of the AdvancedDataGridBaseEx.as
code. Within this function is a single method:
return displayableColumns[columnIndex].colNum;
As I stepped thru the code, I watched the values. columnIndex == 6
and on the execution of this line, the error is thrown. When I hover
the mouse over the components of the line, I get tooltips on
displayableColumns (Array displayableColumns -
mx.controls.AdvancedDataGridBaseEx) and over [columnIndex] (columnIndex
= 6). However, when I hover over the .colNum...I get nothing. In this
case, the error is:
TypeError: Error #1010: A term is undefined and has no properties.
I am really hoping that someone, especially Alex or the like, can
provide some insight to what the heck is happening here because I
really, really need to get past this error.

occurring and why.
As fate would have it, the error is now gone. My coding partner and
I both merged in some changes we were making to that particular ADG

Alex,
when you say a debug build what do you mean? and how do I access
the stack trace? whenever I've heard/used stack trace before, its
always
been on the C# side and the entire listing that's provided when an
exception is thrown...which in this case was included in the original
thread (at the bottom of this email).
Thanks,

Hi, Adrian,
Wow. That's a doozey of an issue. When you're on the bleeding edge,
you tend to bleed a lot. My recent experience with the ADG wasn't
pretty or pleasant, and I bled a lot. But by posting to this group and
various blogs, I found kind souls who helped and finally, through
trial-and-error, found the solution.
Some thoughts on the problem,
- Could it be that after the first (and each) delete, you might need
to refresh your dataprovider for the ADG? It might be worth a try.
- I know the myADG.invalidateDisplayList() helped a lot. It forced
the ADG to fetch the latest data. I overrode the set data() method in
the itemRenderer. No explicit validateDisplayList() method.
- I also used the myADG.invalidateList() elsewhere when the screen
wasn't refreshing.
As Alex Harui suggested, do a debug build and post the entire stack
trace with the linenumbers here. Good luck :)

toolTip=drag a subgroup here to delete them from the project
dragDrop=deleteSubgroupDrop(event)
dragEnter=deleteSubgroupEnter(event) id=image2/
2.) my drag manager is listening and accepts the dragEnter:
private function deleteSubgroupEnter(evt:DragEvent):void
{
var obj:IUIComponent = IUIComponent(evt.currentTarget);
DragManager.acceptDragDrop(obj);
}
2.) and then accepts the dragDrop. On the drop, I am throwing an alert
box up to confirm that the user wants to do this:
private function deleteSubgroupDrop(event:DragEvent):void
{
partsToDelete = new Array;
partsToDelete = currentSubgroups.selectedItems;
subgroupToRemove = currentSubgroups.selectedItem.GroupLabel;
alert.confirm(Are you sure you want to delete this
subgroup: ' + subgroupToRemove +
' from the project?? This cannot be reversed!!,
deleteSubgroupAction);
}
3.) When it hits the alert box, the code then jumps into the core to
render the alert box. The code eventually ends up in the
LayoutManager.as code on line 592, function validateDisplayList():void.
4.) The logic steps thru all of the objects that are on the stage and
for each of them calls the obj.validateDisplayList(); function. All goes
well until it gets to my ADG. Via the validate leg, it goes to the
ADGBaseEx.as code to the function
commitEditedItemPosition(coord:Object):void. During the course of this
function, the columnIndex is manhandled all over the place. Eventually,
it gets to line 4406 where it is checking:
if(colIndex lockedColumnCount)
and passes this check, stepping to the next line of
if (colIndex horizontalScrollPosition + lockedColumnCount)
which fails, then executing a loop against the colIndex. Once the
loop is completed, the final line
actualColIndex =
absoluteToVisibleColumnIndex(displayToAbsoluteColumnIndex(colIndex));
is called, which is on line 7164 of the AdvancedDataGridBaseEx.as
code. Within this function is a single method:
return displayableColumns[columnIndex].colNum;
As I stepped thru the code, I watched the values. columnIndex == 6
and on the execution of this line, the error is thrown. When I hover
the mouse over the components of the line, I get tooltips on
displayableColumns (Array displayableColumns -
mx.controls.AdvancedDataGridBaseEx) and over [columnIndex] (columnIndex
= 6). However, when I hover over the .colNum...I get nothing. In this
case, the error is:
TypeError: Error #1010: A term is undefined and has no properties.
I am really hoping that someone, especially Alex or the like, can
provide some insight to what the heck is happening here because I
really, really need to get past this error.
Best,
Adrian

What does your delete method look like? Try adding some IF statements

it's null or undefined, do a return.

Re: [flexcoders] How to access ADG mx_internal _dropData values: Was -- Identifying which node is the drop target on Grouped ADG

I finally figured it out Here's the solution use namespace mx_internal; var dropData:Object = currentSubgroups.mx_internal::_dropData; var subgroupName:String = dropData.parent.GroupLabel; This gives me the label of my parent node which I can then use to write the data back to my db.
