I've got a little app that is the same old small viewer / large  
image type thing we all know and love.



I've got a slider that sets the scale - ie when the user zooms up,  
the large image zooms up and the 'box' canvas does the invert so  
that it shows what view the user is seeing -- dig?


Now I'm trying to allow the user to move the small box around and  
see that same view with the large image; I've tried the following  
which ALMOST works --when the user moves the box to the right (ie x+ 
+ and y++) the large image goes to the left; but when the user  
moves it BACK the large image doesn't move back to the right.



private function boxMouseDrag(e:MouseEvent):void{
borderBox.transform = box.transform;
var bigM:Matrix = big.transform.matrix.clone();
var boxM:Matrix = new Matrix();
boxM.translate(box.x, box.y);
boxM.invert();
bigM.concat(boxM);
big.transform.matrix = bigM;
//big.transform.matrix.translate(box.x, box.y);
out.text = "dragging " + box.transform.matrix;
}

Hi there,

I had requirment for having radio button for one of the column in Datagrid and 
the user should be able to select only one row radiobutton.

I have used item renderer and assigned it to a RadioButton Group. But I got

Re: [flexcoders] (SOT) Opportunity for FB ? (Hey! Adobe !)

[Sam Lai]

I highly doubt this will happen, mainly because the flagship user of
bugzilla is Mozilla, a web browser company with deep investments in
HTML5, CSS and JS. Their community probably wouldn't be very receptive
either.

>From a personal perspective, I don't think it is a good idea either -
Flash UIs generally aren't good at conveying large amounts of
information. Those that are basically replicate HTML UIs, which
defeats the purpose.

What I'd like to see is Flash being used for visualisations of bug
histories, bugs in components, bug response time statistics etc. Of
course, Mozilla will likely lean to SVG/JS for that, but nevertheless,
that is an area where using Flash would be appropriate.

Use the profiler to see where the time is being spent.  If your attempt to use 
List had poor scrolling it implies that your post renderer is inefficient.

Hi everyone,

I am creating an application which is basically a flex/flash based blog engine. 
When the application is initially loaded, it will retrieve 50 blog post and 
display them on the first page. The problem I am having now is that it takes a 
LONG(5 min) time to load the posts. If I decrease the posts number down to 5, 
the load time is within an acceptable level(7 seconds). However, 5 posts per 
page is just not acceptable.

I will try my best to describe the blog post structure in the following...

1. Each blog post can have pictures and text in it. Each post also has 
"comments" attach to the bottom. Following is a diagram illustrating what a 
post would look like

* abc dummy text *
* (picture) *
* xyz dummy text *
* (picture2) (picture3)*

*Comment 1 *


*Comment 2 *


*Comment 3 *


2. Each post will have variable height due to different content and different 
number of comments

Currently, I put 50 posts in a vbox, and the vbox height is set to 768. The 
vbox wil have a vertical scroll bar for user to scroll down to see the older 
posts. Since vbox will render "everything" before the component can be visually 
displayed, I can understand why it takes such a long time. I have tried to 
modify the code to use variable height "List" with custom itemRenderer instead, 
but the scroll on the list is NOT smooth at all due to itemRenderer recycle and 
re-render with new data.

I am running out of ideas now. Many sites(facebook, blogger, or any other blog 
site) made this easy with PHP/.NET/HTML utilizing "div"+AJAX, but what is the 
best approach with Flex when constructing a blog engine application? Any 
suggestion/help will be greatly appreciated. Thanks!

[flexcoders] Re: Flex error when AdvancedDataGrid made too small.

[Mic]

Cool - I will try this  I had tried the visible="false" but I left it in 
the Layout. After further investigation I narrowed this down to the fact that I 
am using the advanced datagrid footer extensions that are available - Alex's I 
think with a couple of tweeks - and the error is in 
AdvancedDataGridBaseEx.as/protected function drawColumnBackground where var 
lastRow:Object = rowInfo[listItems.length - 1]; resolves to null and causes 
problems downstream when calculating height  includeInLayout = false will 
be a lot easier than resolving the above ... fingers crossed.

[flexcoders] AIR sql parameters - can I use an array ?

[Jim Hayes]

I'm looking for a way to use the "IN" sql syntax and parameters,
something like "SELECT someField FROM someTable WHERE someOtherField IN 
(1,4,6,8,12);" .
Obviously I could build a string query from an array and execute that, but I'd 
rather stay with parameters if at all possible.

If anyone knows, please do tell!
I'm afraid I'm away from my workstation so can't check it at the moment.
Many thanks!

[flexcoders] Adding a close button to a TabBar

[fumeng5]

Hi --

I'm trying to add a close button to a tab in a TabNavigator component. I 
searched the archives and found a post that is nearly 4 years old and was 
hoping there was something newer. 

My Tab is a VBox and I set its icon property to an image. But that image 
appears to the left; how can I align it to the right? Then, how can I assign it 
a click event? 

Any guidance is very much appreciated. 

Thank you

[flexcoders] Re: multiple filters on XMLListCollection how?

This is a little cleaner and less verbose.  Also, if your ComboBox's are
using Objects, you may have to use selectedLabel; instead of
selectedItem:

private function filterData():void
{
  xmlData2.filterFunction = itemFilterFunction;
  xmlData2.refresh()
  Alert.show(xmlData2.length.toString());
}

private function itemFilterFunction( item:Object ):Boolean
{
  var includeItem:Boolean = true;

  // colour filter
  includeItem = colourFilter(item);

  // size filter
  if (includeItem) includeItem = sizeFilter(item);

  return includeItem;
}

private function colourFilter( item:Object ):Boolean
{
  var includeItem:Boolean = true;

  includeItem = (colourFilter.selectedItem == "All colours" ||
item.colour == colourFilter.selectedItem);

  return includeItem;
}

private function sizeFilter( item:Object ):Boolean
{
  var includeItem:Boolean = true;

  includeItem = (sizeFilter.selectedItem == "All sizes" || item.sizes
== sizeFilter.selectedItem);

  return includeItem;
}

[flexcoders] Re: Creating a new ListEvent - how to specify ItemRenderer?

Thanks Tim,

That's not quite the behavior I was looking for though - my List can not be in 
edit mode.

I figured out exactly what I needed - I had to use the indexToItemRenderer 
method of the List - hopefully this will help someone else...

Here's my List KeyDown handler:

private function myListKeyDownHandler(event:KeyboardEvent):void{
var le:ListEvent = new ListEvent(ListEvent.ITEM_CLICK);
var ir:IListItemRenderer =  
myList.indexToItemRenderer(myList.selectedIndex);
le.itemRenderer = ir;

myListClickEvent(le);

[flexcoders] Re: multiple filters on XMLListCollection how?

[Tim Hoff]

Looks like you have a little problem in the logic.  It will either
include all of the items or those that meet the two selected criteria. 
But it won't include all of one and a selected criteria of the other.  A
suggestion is to break up the individual criteria into seperate sub
filterFunctions.  This makes it easier to read and debug; when you start
to use a lot of different filter criteria:

private function filterData():void
{
  xmlData2.filterFunction = itemFilterFunction;
  xmlData2.refresh()
  Alert.show(xmlData2.length.toString());
}

private function itemFilterFunction( item:Object ):Boolean
{
  var includeItem:Boolean = true;

  // colour filter
  includeItem = colourFilterFunction( item );

 // size filter
 if  ( includeItem ) includeItem = sizeFilterFunction( item );

 return includeItem;
}

private function colourFilterFunction( item:Object ):Boolean
{
  if ( colourFilter.selectedItem == "All colours" || item.colour ==
colourFilter.selectedItem )
 {
   return true;
  }
  else
 {
  return false;
 }
}

private function sizeFilterFunction( item:Object ):Boolean
{
  if ( sizeFilter.selectedItem == "All sizes" || item.sizes ==
sizeFilter.selectedItem )
  {
   return true;
  }
  else
  {
   return false;
  }
}

[flexcoders] Re: Accurate way of measuring a datagrid

[djhatrick]

Lulz thanks for the that!  I must be tired ... but i  got this to work, 
correctly,  I have multiple rows that can be longer than others, so this was my 
error...  By the way, is there an event I can subscribe to that will tell me 
when everything is rendered, or do i have to rely on my trusty timeout?

Thanks For your help.

Re: [flexcoders] my SWFLoader wont give me the correct width and height

[Jamie S]

I don't think that's necessarily correct because as I mentioned the
$width and $height protected values are correctly set by the time the
COMPLETE event is dispatched. So the values are known, they just
aren't being updated until the time of the UPDATE_COMPLETE event.

[flexcoders] Datagrid sort function

Addresses and names like so?

[flexcoders] Sticky scrollbars

[djhatrick]

Sticky scrollbars, even with livescrolling set to false..

This is so frustrating, tell me this stuff is fixed in fb4?  
I wouldn't call developing in flex as RIA, there's just too many things like 
these bugs that are annoying... I am venting today.

But the framework drives me crazy when things like this sticky scrolling 
happens, scroll wheel not working on mac, module memory leaks... This stuff has 
to get better.

[flexcoders] Flex 3s generated web service proxies

[nathanpdaniel]

Here's the link to what I'm referring to:
http://livedocs.adobe.com/flex/3/html/help.html?content=data_4.html

I'm importing a web service (WSDL) and having Flex Builder 3 generate all my 
web service proxy classes.  It works great but, I modified my base class - now 
how do I update my WSDL (and the classes generated) without effecting my 
changes? (Modify the templates used to generate the classes)

A second question would be how can I "really" tie this generated service 
 into Cairngorm?  For example, the ServiceLocator has 
getHTTPService("serviceName") and getWebService("serviceName") but, how can I 
do a "getMyService('serviceName')" with the ServiceLocator so I can still use 
the business delegates to send requests to the server.
As it stands, I ignore the delegate and my event command class looks something 
like

public class TestCommand implements Command, IResponder {
 public function event(event:CairngormEvent):void {
  var evt:CustomEvent = event as CustomEvent;
  /*
   HERE IS WHERE MY DELEGATE SHOULD BE
   My code should look like:
   var delegate:CustomDelegate = new CustomDelegate(this);
   delegate.queryServer();

   But instead I have the code below:
  */
  var myServices:MyService = new MyService();
  myService.addEventListener("result", result);
  myService.addEventListener("fault", fault);
  myService.getServerInfo();
 }

 /**
  * EVENT HANDLERS
  **/

 public function result(data:Object):void {
 }
 public function fault(data:Object):void {
 }
}

[flexcoders] Re: Accurate way of measuring a datagrid

[Tim Hoff]

If you can't get it to work, you could always use a Repeater instead. 
In this case, since you want to display all of the items, this would
probably work out better.

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

[Angelo Anolin]

Hi Tim. the sample really looks great.  I would try to analyze the codes this 
weekend since I was pretty occupied these past few days.

The display alone is already what I am hoping to achieve since I don't want to 
separate the age and months on another column.  If I did separate it, then it 
would be easier on my part but it kind of defeats the purpose.

Thanks a bunch!

Regards,

Angelo

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





Ok, here's how I would do it; with efficiency and best-practice in mind:
http://www.timothyh off.com/projects /AgeItemRenderer Sample/AgeItemRe 
ndererSample. 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. DisplayObjectCon tainer, 
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.

Well, the thing is it doesn't work in my case. I attached camera to Video

Hey peepsJust looking for some help with some charting related tasks.

- Can you rotate the axis labels on a LineChart? All the examples i have
used seem to work fine on BarChart but not on LineChart

- Consider the following...





Is it possible to specify the number of axis points and labels? Using the
DateTimeAxis is seems to just try and work out where to plot them but i want
to specify at what intervals to put markers.

- Is it possible to get the color value of a chart line or legend marker? I
want to use the colors for something else and need them to match (other than
specifying my own colors).

Thanks for any help you can give..

i assume the light only turns green whan you actually use the camera like using

We considered this when choosing a bug system for bugs.adobe.com and decided 
the investment wasn't really worth it to us. It's certainly good if someone 
else wants to take it on, but at least 3 years ago if I recall correctly 
bugzilla didn't really have services that you could build a ui around.

[flexcoders] Camera deactivation

[Leon`e]

When I use in my Flex applicaiton Camera.getCamera() function I activate
camera which is signalized by blue light attached to my camera in computer.
How can I deactivate camera? It’s still capturing image (blue light is still
turned on) until I close flex application in the browser.

Instead of setting height and width of a component to 0, try setting visible

[flexcoders] Re: multiple filters on XMLListCollection how?

[valdhor]

What is colourFilter, sizeFilter and selectedItem?

You should be using item. That is the object passed into the filter function. 
Set a breakpoint in the filter function and see what properties item has. Once 
you know, you can write a function to test those properties.

[flexcoders] Re: Remoting Question

[valdhor]

I don't know how ColdFusion handles sessions but PHP uses cookies. IF CF does 
it the same way then you will have a problem as mydomain.com and 
www.mydomain.com would have separate cookies.

I don't know if it is even possible to do what you want in CF. Maybe check the 
documentation or the CF forums.

Re: [flexcoders] Re: Signed RSL penetration

[Simon Bailey]

You know what confuses me though over all this, why hasn't Adobe  
cached the Flex framework in the Flash Player?  An additional 500k on  
the player download would be a miniscule inconvenience in time for the  
user, the way it stands the time added reflects poorly on the actual  
Flex application.


 Releases of the flex framework sdk for caching and flash player  
releases are not so often for that to be a hurdle, surely?


If Adobe are (a) reluctant to release statistics on how many players  
have the framework cached and (b) not going to help push these stats  
up by caching the framework in the player, its going to be a constant  
concern for the developer.

This is due to Google not yet executing network requests from the

Re: [flexcoders] Livecycle CommunicationsException: Communications link failure

[Ward Loockx]

Hello Pedro,

Increasing the connection timeout is not possible because other 
applications use these database too. I try'd to use C3Po but looks like 
the connections still timeout.


Here is an example

I have a remoting service. In the constructor I create my pool.

*Class.forName("com.mysql.jdbc.Driver");
String dbString = "jdbc:mysql://" + properties.getProperty("x") + 
":3306/" + properties.getProperty("x");
DataSource unpooled = 
DataSources.unpooledDataSource(dbString,properties.getProperty(""),properties.getProperty("x"));

this.dataConnection = DataSources.pooledDataSource(unpooled);

*I have a method in the remoting class that get's some data from the 
database. When I call this method below from flex the first +- 10times 
it is not a problem but then I can't get any connection anymore and 
stops after "OPENING CONNECTION". Looks like there is something very 
wrong. Any idea? I just need that the connections stay open during the 
livecycle uptime.


*public String getTeaserUrl(String account)
{
System.out.println("#REQUESTING 
TEASER\n\n");

try
{
System.out.println("OPENING CONNECTION\n");
Connection connect = this.dataConnection.getConnection();
System.out.println("GOT CONNECTION "+connect.toString());
String select = "SELECT FILENAME FROM TEASERS WHERE ACCOUNT = ? LIMIT 0,1";

PreparedStatement statement = connect.prepareStatement(select);
statement.setString(1,account);
ResultSet result = statement.executeQuery();

System.out.println("GOT TEASER RESULT!! "+result.toString());
while(result.next())
{
return "http://xxx/teasers/"+result.getString("FILENAME")+".flv";
}
connect.close();
}
catch(SQLException e)
{
e.printStackTrace();
}
return "";
}

*Greets,
Ward*

1) Try to increase your connection timeout
2) Double check if you are releasing the connections correctly.
3) Use a connection pooling mechanism :) C3P0 is a good one and easy 
to use


If you are using hibernate, it will be very easy to configure it.

Hello Pedro,


Thanks for your reply!


Here are the answers


1) What is your connection timeout?
-> connect timeout 5

2) Are your application and database in the same machine?
-> No (the DAO's make multiple connections to mysql servers and
non of them are installed on the localhost)

3) Are you using some kind of connection pool mechanism? If so,
what are you
using?
-> Don't think so

4) Is it ocurring when your execute some specific query or it occurs
anytime?
-> No, it just occurs after 20minutes. (every connection). So I
get multiple errors in my application

5) What engine are you using(MyISAM, InnoDB, ...) ?
-> MyISAM


Thanks,

[flexcoders] Charting questions

[inevative]

Hey peepsJust looking for some help with some charting related tasks.

- Can you rotate the axis labels on a LineChart? All the examples i have used 
seem to work fine on BarChart but not on LineChart

- Consider the following...


  


Is it possible to specify the number of axis points and labels? Using the 
DateTimeAxis is seems to just try and work out where to plot them but i want to 
specify at what intervals to put markers.

- Is it possible to get the color value of a chart line or legend marker? I 
want to use the colors for something else and need them to match (other than 
specifying my own colors).

Thanks for any help you can give..
