Re: [flexcoders] Re: Flying text or passing text??

[Allan Pichler]

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'... In my example a D.Y.P.P. scroll.
Different Y Pixel Positions :)

Re: [flexcoders] MXML draw dashed line between two text box

[Harish Sivaramakrishnan]

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: Re[flexcoders] moteObject endpoint= vs. Flex settings

[Jake Churchill]

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.

[flexcoders] Re: Binding two elements in a single datagrid column

[Tim Hoff]

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.

[flexcoders] multiple filters on XMLListCollection how?

does anyone have any examples of how i can create multiple filters for use in 
two comboboxes for one datagrid? seems my implementation only filters on one

12 items that are black... AS3 code below

private function filterColourData():void
{

xmlData2.filterFunction = applyColourFilter;
xmlData2.refresh()
Alert.show(xmlData2.length.toString());

}
public function applyColourFilter(item:Object):Boolean
{

if(colourFilter.selectedItem == "All colours")
{
return true

}

else
{
return item.colour == colourFilter.selectedItem;

}






}


 private function filterSizeData():void
{

xmlData2.filterFunction = applySizeFilter;
xmlData2.refresh()

Sorry, I should mention, the 'glitch' seems to be that the playback stops and 
the SOUND_COMPLETE event is dispatched by the SoundChannel.

Yeah, this is a problem, we're sorry :-)  DMV generally stands for the release, 
you should use 3.0.2 in this case I think.  We'll be working on cleaning this

I12 is the iterations for current development, so stuff going into Flex 4.

[flexcoders] Changing background image in datagrid - does not clear out

[luvfotography]

Hi, I've got a datagrid in AIR, alpha=".5" backgroundSize="100%"

and I'm dynamically setting it with:
var picurl:String = 'http://mysite.com/mypic.jpg';

setStyle("backgroundImage", picurl);

and this works, however after 2 or 3 background changes, the pictures don't 
clear and they keep layering each other with some transparency.

I tried clearStyle, no luck,
any way to clear out the old image?

Re: [flexcoders] Binding between components

[mikeashields]

Steve, 

Thanks, your code illuminated some valuable concepts (tangent question, what
does super() do?  I think it introduces all the properties of the class
being extended but if you could confirm it would be great)

but what I am attempting to determine is how to bind/send events from
component A to component B without involving "relay code" on say the
Main.mxml application.

In other words, if Main.mxml contains componentA and componentB can say
componentA declare a Metatag event that can be received by componentB
directly?  And/or can "html type name chains be used such that a
 could have say source="componentA.input1.text"
destination="main.componentB.label.text" />  TIA

[flexcoders] Re: Binding between components

[valdhor]

First off, events will always bubble UP. To pass an event into a
component just inject it.

Here is a simple application that should get you started:


http://www.adobe.com/2006/mxml";
layout="vertical"
 xmlns:Components="components.*"
creationComplete="onCreationComplete()">
 
 
 
 
 
 
 


MyLabelAS.as
package components
{
 import flash.events.MouseEvent;
 import mx.controls.Alert;
 import mx.controls.Label;

 public class MyLabelAS extends Label
 {
 public function MyLabelAS()
 {
 super();
 addEventListener(MouseEvent.CLICK, onMouseClick);
 }

 private function onMouseClick(event:MouseEvent):void
 {
 Alert.show("Mouse Click Event Received");
 }
 }
}

MyLabelMXML.mxml

http://www.adobe.com/2006/mxml";>



If you peruse this, you should be able to see how to move something into
a component as well as inject an event into a component. If you need
anymore help, just ask.


HTH.



Steve

[flexcoders] using ant as the builder in eclipse

[arieljake]

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?

Yeah, something was off so I backed things out so tabbing worked then moved

the cell (with callLater()).  Here's the key down handler on the itemEditor. (I

[flexcoders] Re: Problems using ItemRenderers in DataGrid

A couple of possibilities: Are you using binding for the checked value? The 
other possibility is that after clearing values in your data array you may need 
to refresh() your data array in order to have the changes reflected in your 
datagrid. Hope that helps.

[flexcoders] Re: Binding two elements in a single datagrid column

[Tim Hoff]

Ok, here's how I would do it; with efficiency and best-practice in mind:

http://www.timothyhoff.com/projects/AgeItemRendererSample/AgeItemRendere\
rSample.html

( right click to view source )

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.

I encourage you to read this series
   and
also look at the source code for the Flex controls.  They all follow the
same component life-cycle pattern.

Angelo, look at this sample for how to use an itemEditor.

[flexcoders] Shift-drag on HSlider in FB4

[Daniel McQuillen]

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,  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!

Re: [flexcoders] dmv with flex4 and flexbuilder3 causes "direction" style problem

[Pete Siviter]

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.


HTH,
Pete

Re: [flexcoders] Binding between components

[mikeashields]

I have the following simplified mxml application but want to know how to move
the label to a new component and the Button to a different component (both
components then being in the application).  More specifically I cannot
determine how to "address" the variable names and/or event listeners between
components (ie component A event bubbles up to application but then does not
"bubble" down to component B).  Thanks in advance.

[flexcoders] why does my MXML act differently than my AS?

[Pan Troglodytes]

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.
Here's the code:



http://www.adobe.com/2006/mxml";
  layout="absolute"
  >
  

  

  

  

  

  


  

  

  

  


TestGridRow.mxml:

http://www.adobe.com/2006/mxml";>
  

  



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
lot nicer to add rows in my addCategory function.  But I can't as long as
it's going to be so jittery.

Thanks!

Re: [flexcoders] Re: Binding two elements in a single datagrid column

[Harish Sivaramakrishnan]

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
Harish

Re: [flexcoders] How to pull youtube into a custom Flash/Flex Video Player [1 Attachment]

[Harish Sivaramakrishnan]

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 :)

RE: [flexcoders] Trying Smooth slide transitions with List control item renders or a Repeater...

Here's an example of how to do it:

 

http://www.axelscript.com/2008/09/25/building-a-simple-slider-component/

 

Axel and I used this on http://www.clickstatssports.com/index.cfm 

 

Click the close button in the top right of the flex app to see it slide.
Then click on something else.

 

Basically, this is just a grouping of canvases.  The source code is on
Axel's blog.

Hello All,
I have a HorizontalList that has an ItemRenderer that displays an Image. The
HorizontalList only displays one of my images at a time. I'm trying to make
a transition where the next image slides into the screen. 
Now, since itemRenderers are recycled, I probably can't use a List control.
So, I'm open to using a Repeater.

I've worked with transitions in the ViewStack before. 

Any suggestions or links to slideshow samples that have images slide into
place?

Thanks

Hi Krunal:

This is a simple engineering problem. Solve it just the way you would in any
of your other languages.

Put your buttons in a canvas and increment / decrement the
horizontalScrollPosition on click of next_btn and prev_btn (that could be
one of the ways, there are gazillion others!)

AFAIK it is called a ticker. There are many examples available. Try a Google 
search. Here are a couple to start you off...

[flexcoders] Re: Binding two elements in a single datagrid column

[valdhor]

I thought that was the idea.

In the example, I wanted a new NumericStepper for each data item (Actually two 
new NumericSteppers). If createChildren only runs once, how would you get the 
required output? In other words, can you post your version of the example using 
createChildren ?

[flexcoders] Re: Binding between components

[valdhor]

I looked at your forum thread but can't figure out what you are trying to do. 
Can you post another explanation here.

The important thing to realize about charts is that most things that are 
properties on other components are styles on charts.  I believe they did it 
this way so that you could use them as itemRenderers in ADG's and set them up 
with the styleFunction.

[flexcoders] LCDS Useage Issues

[Kevin Bowers]

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] Re: Flex and Reporting

[Martin Moschitz]

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

RE: [flexcoders] Flying text or passing text??

[Ashish Verma]

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:

 



http://www.adobe.com/2006/mxml";
layout="absolute" creationComplete="(scrollTextHorizontaly())">



  

  

 

   



 

Best,

Ashish

Where can I view those examples? I have used move effect for canvas
and panel. The way I used it was - I made the x or y coordinate of the
moving element to some thing so that it is not visible at all and once
some event is triggered I just move it in using move effect.

Are you suggesting that same thing for this text effect?
