RE: [flexcoders] Flying text or passing text??
The very simple trick to do that. Place the label at the bottom of the
Canvas and take the label text in string. Here is the source code:
?xml version=1.0 encoding=utf-8?
mx:WindowedApplication xmlns:mx=http://www.adobe.com/2006/mxml;

private function scrollTextHorizontaly():void
{
scrollText = lblText.text;
timerObject = new Timer(500);
timerObject.addEventListener(TimerEvent.TIMER,dotheScrolling);
timerObject.start();
}
private function dotheScrolling(event:TimerEvent):void
{
var tempString:String;
tempString = scrollText.substr(1,scrollText.length);
scrollText = tempString + scrollText.charAt(0);
}
]]

[flexcoders] Re: Flex and Reporting
Hi Angelo, thanks for your insights. Finally I ended up doing a similar thing. Since I get my data from PHP Services, I now just send back a print request, which generates the PDF and sends back a link to it, and the Flex Client can navigate to it. I find that this is probably the best solution if you need complex pdfs to be generated, as AlivePDF and FlexReport etc. still have some limitations and I also dont know about their performance. Thanks for the insights, Martin
[flexcoders] LCDS Useage Issues
Good Morning, I wonder if anybody could possibly help me out with some issues that we are having with an installation of LCDS. We are evaluating the software for a large project that we are planning, but cannot seem to get LCDS to run under JBoss. We have successfully connected to our Oracle database, with a whole bunch of tables being created. We can successfully view the LiveCycle control panel, log into it and so on. However, we cannot seem to find the config files or find which port the LCDS is listening on. If you could possibly point us toward some information or tutorials I'd be most grateful. We are running on a windows machine, as we had many problems trying to install on Linux. Incidentally, we also had problems with the windows install, but eventually it worked. Many thanks, Kevin Bowers

[flexcoders] How to pull youtube into a custom Flash/Flex Video Player
I found the docs from Google on how to query the user's information, but what element do you use as the source for the video player?
Re: [flexcoders] How to pull youtube into a custom Flash/Flex Video Player [1 Attachment]
Google does not give you direct access to the video source through their APIs. You will need to scrap (steal) that Information from the youtube page. I had written a class which does it for some testing purposes. I have attached the source in this mail. But AFAIK, its illegal to scrap information from their site. You can take a look at the attached code to get an idea. Again, use it at your own risk :) Cheers Harish On Wed, Jun 17, 2009 at 9:03 PM, Wally Kolcz wko...@isavepets.com wrote: I found the docs from Google on how to query the user's information, but what element do you use as the source for the video player?

Re: [flexcoders] Re: Binding two elements in a single datagrid column
Listen to the change event / enter event on the NumericSteppers and dispatch
an event to update the DataProvider with the new values. Once you override
the itemRenderer with a custom Renderer, you need to handle the commit of
values back to the DataProvider.
You can do something similar to this. Please note that this is NOT exact
code, but you could use this approach.
nsOutwardAgeYear.addEventListener(change onnsOutwardChange);
private function onnsOutwardChange(event:Event):void
{
dispatchEvent(new CustomEvent(valueChanged, (event.target as
NumericStepper).value);
}
*The custom event can have an extra property that holds the value of the
Stepper.*
*In your main app, add a listener to your DataGrid*
dg.addEventListener(CustomEvent.VALUE_CHANGED, onvalueChanged);
private function onvalueChanged(event:CustomEvent):void
{
var selectedObject:Object = datagrid.selectedItem
selectedObject.Age = event.value;
(datagrid.dataProvider as ArrayCollection).setItemAt(selectedObject,
datagrid.selectedIndex)
}
Hope this helps!
Cheers

[flexcoders] why does my MXML act differently than my AS?
I have a test program that, as far as I can tell, does the same thing using
an MXML component and the equivalent actionscript. When I click on the
button to execute the AS version, everything is fine. But when I click on
the button to execute the MXML version, I get a layout flicker. It's bad
enough that if you try to click on the MXML button over and over really
fast, you'll wind up clicking the main app and the menu will go away.

I've dug through the generated code and have not been able to find anything
that I think would account for the problem. This is frustrating, because
what I really want to do is a more complicated MXML component to make it a

it's going to be so jittery.

Re: [flexcoders] dmv with flex4 and flexbuilder3 causes direction style problem
Hi there, I think you'd need to take the datavisualization.swc from flashbuilder 4.0.0 sdk (presumably installed under your drive_c in wine) and use it in your sdk folder under flexbulder linux. I spent quite a bit of time looking at the same problem and re- compiled datavisualization after editing the source. This stopped the compiler errors with 'direction' but caused problems further down the line (though I was working in gumbo which I think isn't compatible with datavisualzations from earlier versions). I fixed the problem once I copied the correct datavisualization.swc from the 4.0.0 folder. There's a whole bunch of files you need to copy, but you can google it if you've never done it before.

[flexcoders] Shift-drag on HSlider in FB4
Does anybody have any tips for capturing a slider drag with SHIFT keyboard event? MouseEvents have the handy shiftkey property for capturing events with SHIFT key depressed. However, s:HSlider/ doesn't seem to launch any helpful mouse events (e.g. mouseUp) and the events it does launch (e.g. change) don't have the event.shiftkey property. I could capture the shift key state in my own boolean flag somewhere by using keyUp and keyDown handlers on the slider or parent containers, but then the issue of component focus gets in the way and it doesn't behave smoothly. There's probably a really easy answer to this that -- like so many before -- eludes my slow thinking. Thanks for any suggestions! - Daniel McQ

Two main differences Steve:
First, use createChildren to add the children, instead of in set data.
I suspect that what's happening with the way you are doing it is that
each time the data is changed (which, because the itemRenderers are
recycled, happens on every scroll), the instance of the child is
attempted to be added to the display list. I can't see the code in
flash.display.DisplayObjectContainer, but I suspect that the code is
checking to see if the instance exists already and/or re-parenting it.
Either way, this is an un-necessary step. You only need to add the
child once and then use the data to control it's state.
Second, for efficiency, try to avoid using containers in itemRenderers.
A good practice is to extend UIComponent and do the layout manually.
It's a little more work, but you get some good performance benefits.

Subject: [flexcoders] Re: using arrow keys to move around editable datagrid
Thanks for the reply. The custom grid wasn't moving from cell to cell based
on typing the tab key so I didn't think that simulated events would do the
trick. I got it to work but I wonder if there is a cleaner way.
The grid has a custom itemEditor that extends TextInput. The itemEditor has a
listener for keydown that calls this function

{
trace(TextInputEditor.onKeyDown);
//trace(currentTarget: + event.currentTarget.toString());

[flexcoders] using ant as the builder in eclipse
If i have one application and one library, in my ant file that i have specified as the builder in the project settings for the application, am I supposed to set depends=library-build or not? I have the library specified as a dependency in the project properties, and it seems as if the library's build.xml file is being called automatically when I build the application, but I don't see how to get the application's build to wait till the library is done compiling. The alternative is to use depends=library-build to make sure they happen in the correct order, but the only way I see to disable the application build from automatically triggering the library build is to remove the link in the project properties, but then will code references work in the editor?? How are people handling this?

Re[flexcoders] moteObject endpoint= vs. Flex settings
Primarily because I cannot seem to understand the CF Root Folder / Webroot /
Root URL for a non-localhost setup (ie //DevServer/ColdFusion8/wwwroot
along with http://testingIP:8500/projname???) I have taken to using
the endpoint property in RemoteObject as follows:
mx:RemoteObject destination=ColdFusion
source=test.cfcs.QuoteService
endpoint=http://174.1.159.113:8500/flex2gateway/;
method=getQuote
arguments={event.symbol}
What is the downside of this??? I assume if the CF-Flex settings are set
properly then flex uses those to set the endpoint so in theory the
benefit would be not having to enter endpoint in each time (in which case I
actually prefer the verbiosity of the above method) but is there any other
reason/benefit to either not using the endpoint OR to setting up the CF-Flex
link??

[flexcoders] Re: Binding two elements in a single datagrid column
No response huh? Ok, you're welcome valdhor (Steve). One thing to
point out is that all flex controls, containers and components extend
UIComponent. Therefore, they all use the createChildren(),
commitProperties(), measure(), layoutChrome() and updateDisplayList()
methods. This applies to itemRenderers as well. The Flex engineers did
a great job developing the component life-cycle, and each of these
functions has a specific purpose. So really it's fine, if some other
practice, that circumvents the intended use of these methods, works for
you. However, it's propbably not fair to spread bad habits like this to
others; that are just learning.

added
to
the display list everytime that the data is set. But usually, you
only
need to add them once.

I'm with you Steve; about using AS for an itemRenderer. I do

you would use addChild in the set data function though; rather

mx:itemRenderer
mx:Component
mx:HBox horizontalGap=5 horizontalAlign=center
width=100% horizontalScrollPolicy=off
verticalScrollPolicy=off
mx:NumericStepper id=nsOutwardAgeYear value={ data.Age
} minimum=0 maximum=200 stepSize=1 width=50
textAlign=center/
mx:NumericStepper id=nsOutwardAgeMonths value={
data.Months } minimum=0 maximum=200 stepSize=1
width=50
textAlign=center/
/mx:HBox
/mx:Component
/mx:itemRenderer
For the HBox, notice the use of horizontalGap, instead of a
spacer
as
well. Just cleans it up a bit.

RE: Re[flexcoders] moteObject endpoint= vs. Flex settings
To my knowledge, there is now benefit or detriment to doing it either way.
I do the same thing and I know other people who do also. I actually find it
easier to deploy this way because I always have some kind of config xml file
that loads at startup which contains things like the domain and endpoint in
it. That way, when I deploy an app, the only thing I need to worry about
changing is the config file. I don't spend a bunch of time trying to figure
out server configurations and difference between my environment and a
production/staging environment.

Subject: Re[flexcoders] moteObject endpoint= vs. Flex settings
Primarily because I cannot seem to understand the CF Root Folder / Webroot /
Root URL for a non-localhost setup (ie //DevServer/ColdFusion8/wwwroot
along with http://testingIP:8500/projname???) I have taken to using
the endpoint property in RemoteObject as follows:
mx:RemoteObject destination=ColdFusion
source=test.cfcs.QuoteService
endpoint=http://174.1.159.113:8500/flex2gateway/;
method=getQuote
arguments={event.symbol}
What is the downside of this??? I assume if the CF-Flex settings are set
properly then flex uses those to set the endpoint so in theory the
benefit would be not having to enter endpoint in each time (in which case I
actually prefer the verbiosity of the above method) but is there any other
reason/benefit to either not using the endpoint OR to setting up the CF-Flex
link??

Re: [flexcoders] MXML draw dashed line between two text box
You can style the HRule Component to draw a dashed / dotted line or even change the skin of the HRule component by overriding the programmatic skin that is drawn by default.

Re: [flexcoders] Re: Flying text or passing text??
I have a more outrageous hippie version of a marquee on my experimental site. And as a sidenote the term marquee is probably the right one, but the fact that my coding career started back in 1982 and I used to be part of the C64/Amiga demo scene I will insist that it's a 'scroller'...
