[flexcoders] Question on Flex Script Execution + Alert.show
Hi FlexCoders,
This has puzzled me a bit..
I have the following scripts in my application:
private var myAlert:int;
private function testFunction(evt:Event):void
{
Alert.show('do you want to proceed', 'Title', Alert.YES | Alert.NO, null,
alertHandler, null, Alert.YES);
if(myAlert == 1)
{
// Do Something here
}
else
{
// Do other thing here
}
}
Private function alertHandler(evt:CloseEvent)
{
if(evt.Detail == Alert.YES)
{
myAlert = 1;
}
else
{
myAlert = -1;
}
}
Now, what puzzles me is that the script after the Alert.show is triggered, the
scripts following it are also triggered.
Is there a way to ensure that the script following the Alert.show alert box
would only be executed after the Yes or No buttons has been pressed?
I won't be able to move the scripts after the Alert.show script to the
alertHandler event since there are some objects being set / modified prior to
the alert being called.
Inputs highly appreciated.
Thanks.
Re: [flexcoders] Flex Function and Web Service ResultHandler Question
Hi Tracy,
Thanks for the input.
How can I then pass some objects and variables to the ResultHandler which I
have made some modifications prior to calling the web service operation?
Would my last resort be on declaring variables and objects that would be
visible across the whole application?
Thanks and regards,
Angelo

Function and Web Service ResultHandler Question
Hi FlexCoders,
Needing your input on the following:
I have created a function for the dragevent of a
list.
Code is as follows:
private function myFunction(evt: DragEvent) :void
{
var nameID:String = 'Angelo';
// Call a webservice operation here
ws.GetStatus( nameID);
Alert.show(String( _xmlGetStatus) , 'myFunction' );
// I need to use the _xmlGetStatus here...
// But the _xmlGetStatus is NULL?
// Although in the Result Handler, it is not NULL.
}
private function getStatusResultHand ler(event: ResultEvent)
:void
{
_xmlGetStatus = XML(event.result) ;
Alert.show(String( _xmlGetStatus) , 'getStatusResultHan dler');
}
The result handler for the GetStatus web service
operation populates an XML variable which I declared on top of the script (i.e.
private var _xmlGetStatus: XML;).
When I run my application, myFunction executes but
the alert that is shown first is the one in the function myFunction, instead of
the one in the result handler.
I need to use the values in the XML variable
_xmlGetStatus for further operations in function myFunction, but then the value
is not populated right away.
Any way to handle this?
Thanks and regards,
Angelo
[flexcoders] Find Actual Width After Setting Percent Width
I have a canvas container with=100%. When the user clicks a button, the container is set to percentWidth=20, and I need to immediately know the new width so that I can properly re-size elements in the container to match the new width. From what I can tell, the LayoutManager doesn't get to measuring the new width of the container right away. If the user clicks the button again, the LayoutManager has done it's thing and has set the width value of the canvas. So the question is, how do I get the new width of the canvas as soon as I set percentWidth=20?

*Subject:* [flexcoders] Add mxml component to NativeApplication instance
Hi,
Situation:
I've simplified my problem to just a few lines of AS mxml (see below).
What I'm trying to do is easy: Create a custom NativeWindow instance that
has an mxml component as it's child.
Problem:
I can't get the component to show and it 'disappears' for some reason.
Code:
package
{
import flash.display.NativeWindow;
import flash.display.NativeWindowInitOptions;
import flash.display.NativeWindowSystemChrome;
public class CanvasWindow extends NativeWindow
{
public function CanvasWindow()
{
var options:NativeWindowInitOptions = new NativeWindowInitOptions();
options.systemChrome = NativeWindowSystemChrome.STANDARD;
options.transparent = false;
super(options);
var ct:CanvasTest = new CanvasTest();
trace(ct = + ct);
this.stage.addChild(ct);
trace(ct = + ct);
}
}
}
?xml version=1.0 encoding=utf-8?
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml; width=400
height=300
mx:Button x=178 y=138 label=Button/
/mx:Canvas
?xml version=1.0 encoding=utf-8?
mx:WindowedApplication xmlns:mx=http://www.adobe.com/2006/mxml;

mx:Script
![CDATA[
import mx.core.Window;
public function init():void
{
var newWindow:NativeWindow = new CanvasWindow();
newWindow.activate();
}
]]
/mx:Script
/mx:WindowedApplication
As you can see I've added two traces. The first traces my CanvasTest
instance, while the second one traces null. The component is also not
displayed.
I couldn't find a lot of information about this, and what I did find was
about an alpha about Apollo (hacked together).
So, what's going wrong here?
Thanks for reading!
[flexcoders] Re: SharedObject - do I need to stop it flushing at app exit?
Hi Tracy, that is when I assign the values - when the Save Prefs button is clicked. However, when the app quits, Flex autoflushes again, and the user might have changed some of the params but does not want them as Prefs. It seems that this autoflush remembers where the values came from e.g. soDrctrDash.data.ddParamsVO.vpID = drctrDashParamsVO.vpID; soDrctrDash.data.ddParamsVO.rvpID = drctrDashParamsVO.rvpID; soDrctrDash.data.ddParamsVO.divID = drctrDashParamsVO.divID; and overwrites the saved user prefs with whatever the most recent values are. I have never had this happen before and wonder if it is anything to do with flash.net.registerClassAlias(soDrctrDash.DrctrDashParamsVO, DrctrDashParamsVO); soDrctrDash = SharedObject.getLocal(drctrDash); TIA, Mic. --- In flexcoders@yahoogroups.com, Tracy Spratt tr...@... wrote: Don't assign values to the so until the user clicks the save prefs.

[flexcoders] Grouping issue on Advanced DataGrid
Hello, I've got an advanced datagrid with 5 columns, The number_Group column has data like this... 1-10 1-10 11-20 11-20 11-20 21-30 21-30 21-30 41-50 101-110 When I apply Grouping, it works as expected but the 101-110 group is displayed before the 11-20 group. I've tried to set groupingField.numeric = true but that screws it up even more... because 11-20 isn't a number I'm guessing. Does anyone know a way around this? I could change the number_Group column to this... 1 1 11 11 21 41 101 and groupingField.numeric = true should work but I need the Grouping display to show 1-10, 11-20. Perhaps I can intercept this and modify it? Thanks, Nick

[flexcoders] 'sans_nom_3.swc' does not have a recognized extension
hello,
I have already send this message but there's no answer, so I try a new time,
it's oimportant for me but I can't find any help in forums nor tutorials.
I am a beginner into flex, and in Flash, so I ask you to tolerate me!
here is my problem: I want to study the use of flash components into flex. So I
first created a symbol in flash, put one instance of this symbol in a FLA file,
and , then I exported it for flex by clicking the right item in flash.
Then, I ran flex, I entered the .swc in the library path of my new project, and
I entered this code:
package {
import flash.display.MovieClip;
import flash.display.Sprite;
public class pont_flash_flex_2 extends Sprite
{
public function pont_flash_flex_2()
{
[Embed(source='sans_nom_3.swc',symbol='occu_mon_symbole')]
var ClasseSymbole:Class;
var ma_classe:MovieClip=new ClasseSymbole();
addChild(ma_classe);
}
}
}
Here is the error message:
'sans_nom_3.swc' does not have a recognized extension, and a mimeType was not
provided pont_flash_flex_2/src pont_flash_flex_2.as line 9 1251140352156 15
and:
Unable to transcode sans_nom_3.swc. pont_flash_flex_2/src
pont_flash_flex_2.as line 9 1251140352156 16
Here is my question: is this code right?
in this case, the error comes from the flash part (creation of the symbol,
maybe its occurence's name).
thank you,
lolveley.

Re: [flexcoders] Flex Function and Web Service ResultHandler Question
Hi Tracy,
You mentioned that this is the only way...
But doesn't this kind of programming limits what the developer could actually
do?
I mean for example, you have coded in the dragDrop event of a list control. In
the said event, you need to get some data through a web service. The whole
operation is dependent on the event handler for the dragdrop. If you would
only be allowed to process the operations further in the result handler of the
web service, how could you then utilize the event which was the parameter in
your dragdrop event?
I think this question also goes the same for the Alert.show function where the
result handler deviates from the function/event with which it was executed. If
the continuation of execution would be on the Alert handler, it would be quite
tedious on the part of the developer to be able to gather the
variables/objects/handlers from the original function/event.
I am pretty sure Adobe / Flex team has thought about this but I may be doing
things wrong. So I would appreciate everyone's input. I am in a bind right
now cause this limitation(?) hampers me from being a lot more productive with
Flex.
Thanks.
Angelo

Needing your input on the following:
I have created a function for the dragevent of a

Code is as follows:
private function myFunction(evt: DragEvent) :void
{
var nameID:String = 'Angelo';
// Call a webservice operation here

// But the _xmlGetStatus is NULL?
// Although in the Result Handler, it is not NULL.
}
private function getStatusResultHand ler(event: ResultEvent)
:void
{
_xmlGetStatus = XML(event.result) ;
Alert.show(String( _xmlGetStatus) , 'getStatusResultHan dler');
}
The result handler for the GetStatus web service
operation populates an XML variable which I declared on top of the script (i.e.
private var _xmlGetStatus: XML;).
When I run my application, myFunction executes but
the alert that is shown first is the one in the function myFunction, instead of
the one in the result handler.
I need to use the values in the XML variable
_xmlGetStatus for further operations in function myFunction, but then the value
is not populated right away.
Any way to handle this?

Re: [flexcoders] Question on Flex Script Execution + Alert.show
Alert.show is async, so move the code after Alert.show to the alertHandler
method after your if/else block that's already in there.

Hi FlexCoders,

Now, what puzzles me is that the script after the Alert.show is triggered,
the scripts following it are also triggered.
Is there a way to ensure that the script following the Alert.show alert box
would only be executed after the Yes or No buttons has been pressed?
I won't be able to move the scripts after the Alert.show script to the
alertHandler event since there are some objects being set / modified prior
to the alert being called.
Inputs highly appreciated.

RE: [flexcoders] An Array of Class Objects???
Array and ArrayCollection do not enforce any kind of type checking on their elements… each element can be anything. If you need strongly-typed elements, use Vector: macList:Vector.deviceClass BTW, the convention is to start class names with a capital letter.

[flexcoders] Re: Find Actual Width After Setting Percent Width
The code below should demonstrate the issue more specifically.
What you get when the clicked() function is called, shows that there is a
slight delay in getting the width of the container. You'll note that the trace
statement returns the original width as does the txtWidth field.
You will note, however, that if you bind to the width of the container, you do
get the correct width of the canvas. What I infer from this is that there is a
delay in FlashPlayer/Air in having the width value set.
If, however, you use the previous example, posted Beau, this works, presumably
because the item you are re-sizing is within a container and the LayoutManager
deals with nested items first, as I recall.
Why the validateNow() function doesn't complete before moving on to the other
two elements in the clicked() function, wasn't what I expected. This is
probably a speed thing in the function so as to not hold up other items while
the item is being validated???

[flexcoders] Password Protection in Flex
Hello, I am new to flex but am immensely enjoying the charting/dashboard capabilities. As I begin to put sensitive data together for certain clients, I am wondering if there is a way to password protect the swf output. For instance, I would like to send a link to a client with their requested business-intell dashboard. When he/she opens this link, I want the first screen of the swf file to ask for a password. Once the password it entered correctly, the dashboard becomes functional. Any code suggestions or links to relevant examples? Thanks in advance, Alex

Re: [Spam] [flexcoders] Question on Flex Script Execution + Alert.show
I'm not sure if this technique is frowned upon but...
You could have a new private var boolAlertContinue:Boolean = false;
In your alertHandler function, you would set it to true... boolAlertContinue
= true;
And after the Alert.show and before the if(myAlert == 1) you need to do a do
while loop...
do {
//Not sure if there's a 'dummy' command to prevent CPU hog so we'll
just check the time...
var dtmNow:Date = new Date();
}
while (boolAlertContinue);
or you could probably initialise your myAlert:int = null and in the do ...
while loop check for (myAlert != null)
