Re: [flexcoders] dmv with flex4 and flexbuilder3 causes direction style problem
Hi Thomas, Glad it worked. I am afraid I don't really use httpservice as I am using amfphp for my server communications (which seems to work out the box in flex 4), but my only suggestions are to try other relative paths like ./path/to/file to see if that works? Or use a function to find the absolute path of the default location to return to the client (php script would do it I think). Just random ideas... Of course, it should be compatible, so maybe file a bug? Regards, Pete On 18 Jun 2009, at 08:43, thomas parquier wrote: Hi Pete, Thank you, the application compiles fine now.

[flexcoders] Re: Binding two elements in a single datagrid column
Actually, I am still reading through Peter Ent's dissertation on the subject.
From what I have learned, what I am doing is not wrong per se. It works and
works very well for the smaller data sets that I use (Hundreds of rows, rather
than thousands). Also, doing it the way I do is a lot more readable. I don't
see it as a bad habit - just one way of many to get something done.
I think that if I had a performance issue I would go back and tweak item
renderers (And other components) to be more efficient.
From a new users perspective, if I had seen your item renderer when I first
started using Flex, I would have been totally intimidated and probably tried
very hard never to need an item renderer.

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
http://www.adobe.com/devnet/flex/articles/itemrenderers_pt5.html and

[flexcoders] Fooling the runtime over type
I've seen a similar question asked on flex coders before, but it was about 2006 so things may have moved on since then! I'm trying to fool the runtime into thinking one object is of a different type. The object is of type ObjectProxy so it can handle all the calls to the object it is proxying, and I'm trying to use the Proxy in place of the object it is proxying... Clear as mud? Basically... var obj : ObjectProxy = new ObjectProxy( new MyObject() ); var newObj : * = obj; works because the newObj variable is untyped. This isn't acceptable for a whole host of reasons (the loudest one appears to be that code hinting stops working at that point). var obj : ObjectProxy = new ObjectProxy( new MyObject() ); var newObj : MyObject = obj; throws a Type Coercion error as it cannot convert the Proxy to the strong type. Is there any way of fooling the runtime into thinking the type of the ObjectProxy is actually that of MyObject? Am I actually going mad, and trying to do something foolhardy and impossible? Gk.

[flexcoders] Copy ToolTip to Clipboard
Hi all, I have a challenging little req't. We're using tooltips all over the place on our app. I need to be able to setup the tooltips so that we can have a copy button or text in the tooltip that our user can click to copy the contents of the tooltip to the system clipboard. This needs to be usable on everything from a large ADG with thousands of tooltips to the simple stuff. I thought I had seen a solution for this at one point in time but cannot for the life of me find it again. Help!? Thanks, adrian

[flexcoders] Re: Binding two elements in a single datagrid column
Oh heck, I just can't resist. From what I have learned, what I am doing is not wrong per se. It works and works very well for the smaller data sets that I use (Hundreds of rows, rather than thousands). Also, doing it the way I do is a lot more readable. I don't see it as a bad habit - just one way of many to get something done. For some reason, you are thinking that each item in a data set has an itemRenderer; they don't There are only enough itemRenderers instantiated, to display in the scrollable area of a list; and sometimes one or two more. When the list scrolls or the dataProvider changes, the itemRenderers that have already been instantiated are recycled. So, it doesn't matter if there are 100 or 1000 items in the dataProvider. What matters is how many objects on the screen need to be rendered.Each time that an itemRenderer is recycled, it's data is set; but it isn't re-instantiated. So performing tasks like addChild are redundant at that point. Agreed, there's usually more than one way to accomplish a task in flex and everyone is entitled to their opinion and preferred practices. If you want to add children to a component every time that the data changes, go for it. To me though, it just doesn't make sense to try to re-add something that's already there. I think that if I had a performance issue I would go back and tweak item renderers (And other components) to be more efficient. We're talking milliseconds here, so perception is always relative. I imagine that people that have only used dial-up, are accustomed to and happy with a certain level of performance. That is, until they experience broadband for the first time. From a new users perspective, if I had seen your item renderer when I first started using Flex, I would have been totally intimidated and probably tried very hard never to need an item renderer. If you look back at the first few posts on this thread, you'll see that my response was a solution for Angelo's simple in-line mxml itemRenderer. You introduced an AS solution. Agreed, beginners will find AS itemRenderers intimidating. Oh well, you have to learn sometime. So, I don't want to make this a big deal. At the end of the day, if it works for you, that's all that matters. That doesn't mean though, in a public forum, that best-practices shouldn't be pointed out. In the past, I've had several occasions where I've just been flat-out wrong on this list; or should I say strong and wrong, because of ego and stubbornness. :) . The good thing is that people have nicely pointed out my errors and I've learned from it; as well as others following along. On this specific issue though, I stand by my assertions completely. Anyway, nice discussing this with you Steve.

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.

[flexcoders] ComboBox : HBox as ItemRenderer - textRollOverColor problem
So I have an itemRenderer which simply displays text and an
image...something like:
mx:HBox
mx:Image /
mx:Label text={data.anme} /
/mx:HBox
My ComboBox is configured in MXML such as:
mx:ComboBox id=foo itemRenderer=MyComboRenderer /
My CSS has:
ComboBox {
textRollOverColor=0xFF;
}
So what I want is for the items in my ComboBox (foo) to have red
text on the Label when the item is rolled over...but this isn't
happening. How can I get this to work? I should mention I prefer to
keep the style stuff out of the code and in a CSS file.

[flexcoders] Re: ComboBox : HBox as ItemRenderer - textRollOverColor problem
So my fix is this:
MyComboRenderer
mx:HBox rollOver=onRollOver(); rollOut=onRollOut();
mx:Script
...
private function onRollOver():void {
lblGroup.setStyle(color, getStyle(textRollOverColor));
}
private function onRollOut():void {
lblGroup.setStyle(color, getStyle(color));
}
...
/mx:Script
/mx:HBox
You'll notice I just listen for the rollOver/rollOut events and handle
it there. It uses the textRollOverColor style that is set on the
ComboBox :)

[flexcoders] Creating a new ListEvent - how to specify ItemRenderer?
I have a List that handles a Click event - the ClickEvent takes a ListEvent, and inside that handler I have access to the ListEvent's itemRenderer property. This allows me to align a button next to the row that I have clicked on. I also want to trigger this click event when the user uses the keyboard up and down arrow keys to navigate the list. Inside my KeyDown handler I want to call my List click handler. The trick is, how do I specify the itemRenderer for the new ListClick event or get access to it? eg. var le:ListEvent = new ListEvent(ListEvent.CLICK,.. .. .., myItemRenderer);

The trick is, how do I specify the itemRenderer for the new ListClick event or get access to it? eg. var le:ListEvent = new ListEvent(ListEvent.CLICK,.. .. .., myItemRenderer);
[flexcoders] Re: Copy ToolTip to Clipboard
Doesn't ring any bells for me. Just a thought... The tooltip is context sensitive (ie. it depends on where the mouse is an any particular moment).

[flexcoders] Adding Repeater elements to different containers

[flexcoders] Remoting Question
I have an app that I'm having some issues accessing a session variable that is set in ColdFusion. I think it's due to my services-config.xml file having the flexgateway url set to have the www. If I'm at www.mydomain.com I can make the remoting call and have the cfc return the session variable to Flex. If I go to just http://mydomain.com then I seem to have an issue. I created a cross domain policy file to allow with the www and without but because the session variable is set on the domain without the www and then the remoting call is trying to access the cfc with the www the session variables are being reset. I can force the page to always go to www but wanted to see if others have run into this and the best way to handle it. Thanks, Ben

[flexcoders] Accurate way to measure variable row datagrid
Is there an accurate way to measure a datagrid's height with variable row height? Can I extend datagrid and extend something to find this property? By the way, are other people having issues with posts not showing up on flexcoders? What's the delay before something shows up, I forget who moderates this list, is it because they all need to be approved?

[flexcoders] my SWFLoader wont give me the correct width and height
I'm using a SWFLoader to load in an image and i have a handler function for COMPLETE. In this load complete handler, i'm trying to get the size of the SWFLoader instance by using swfLoader.width, swfLoader.height but it always gives me 0. if I set a breakpoint, i can see that the $width and $height protected properties are correct but no matter what I do I can't get the public width and height properties to update. i've tried using validateNow(), invalidateSize(), validateSize() and whatever else I can think of but the width and hight are still always 0. And I noticed that if i check the width and height at some later point in the program, the values are correct. Does anybody know how to force SWFLoader to update its width and height? Jamie

Thanks for that, but unfortunately that method is inaccurate( Maybe it doesn't

See my examples:

Measuring each row height 560
It's off by 72 pixels... that's quite a difference.

That sorta works. It's a way of getting notified when the properties
do finally get updated . But i still have to do if( swfLoader.width

run that piece of code once, I would have to remove the listener after

I still don't understand why calling swfLoader.validateNow() does not
work when I try to call it in the 'complete' handler.

[flexcoders] Flex error when AdvancedDataGrid made too small.
In an application where 8 panels exist on the screen with each panel containing a chart or an advanced datagrid (corporate dashboard), any portlet can be zoomed to fill the whole screen, and I was doing this by setting height and width of the other 5 to 0. Trying to debug the error I was getting, I discovered that if you make an AdvancedDataGrid less than about 40 (cannot remember exact cutoff) Flex gives an error of: TypeError: Error #1009: Cannot access a property or method of a null object reference. at mx.controls::AdvancedDataGridBaseEx/drawColumnBackground()[C:\work\flex\dmv_automation\projects\datavisualisation\src\mx\controls\AdvancedDataGridBaseEx.as:3503] etc. It looks like it is too small to draw - Alice would tell it that it took the wrong pill :-) Is there a way around this? TIA, Mic
RE: [flexcoders] Re: Accurate way of measuring a datagrid
Was 560 really the right number? Or was it closer to 612? You have to factor
in viewMetrics as well. Are you using a custom renderer and have verified it
measures correctly?

RE: [flexcoders] my SWFLoader wont give me the correct width and height
I don't think there is a way to force SWFLoader to know its width when it
dispatches the COMPLETE event. That event means the bytes are downloaded, but
they may not be fully consumed yet. However, it should be available on the
UPDATE_COMPLETE that follows the COMPLETE event.
