[flexcoders] mxlm component instantiation using ActionScript

[normc_actionscript]

Is it possible/advisable to add an mxml component to the application by doing 
this from a Flex container:
var myComp:myCustomPanel = new myCustomPanel(); 
// myCustomPanel is myCustomPanel.mxml containing a Panel container.
AddChild(myComp)

On creation complete of myCustomPanel.mxml I attempt to set text in a 
 sub component, but error occurs at runtime.

Any other suggestions on how to pop up panels in the application? 
Popup manager?
Include them on application startup and toggle visibility?

Thanks,
Norm C.

[flexcoders] Re: Cairngorm Problem with Event and ModelLocator

[normc_actionscript]

Hi. Are those variabes bound?
var listUsers:ArrayCollection = model.listUsers;
var totalRows:int = model.countUsers;

I'm new to Cairngorm, so I'm not sure,off the top of my head, how to assign 
binding from a script. Within a component, it's done with squigly brackets {}.

Also, is your whole ModelLocator class marked as Bindable?

[flexcoders] Re: newbie q: transition from flash to flex (long-ish)

[normc_actionscript]

I can't see how you would do it any differently.
Maybe you can take advantage of Flex's databinding is some way, not sure. I'm a 
bit of a newbie myself, so maybe others have more to say.

See link for solution.

[flexcoders] AS2 AttachMovie equivelant in AS3/Flex

[normc_actionscript]

My Flex app loads an external SWF via a SWFLoader.
Said SWF contains movie clips in the library, with class definitions.

In my Flex app, I do have the class name (a string) of the movie clips in the 
SWF.

How can I show those movie clips in my Flex app?

Thanks!

[flexcoders] Re: DataGrid is blank

[normc_actionscript]

Thanks for the help, makes sense. 
I'll make a new component with a List and label above, and repeat that. 
DataGrid is overkill for what's needed anyway.

Norm

[flexcoders] DataGrid is blank

[normc_actionscript]

My DataGrid contains data, but is now showing it. (See itemClickEvent
function.)

Anybody know why?

(PS feel free to critisize any other aspect of my code, i'm just
learning)

public function itemClickEvent(e:ListEvent):void{

Alert.show(String(e.target.selectedItem));

// THIS SHOWS WHAT'S EXPECTED

}

public function addToGrid(e:Event):void{

// This adds several 1 column dataGrids to an hbox, because I need lists
with column headers.

// One dataGrid won't work, because the lists are different lengths.





categories = new XMLList(urlLoader.data)



for each (var cat:XML in categories.*){

var partsGrid:DataGrid = new DataGrid();



var partsListCollection:XMLListCollection = new
XMLListCollection(cat.children())

var df:XML=XML(partsListCollection.getItemAt(0))

partsGrid.dataProvider = partsListCollection;



var dgc:DataGridColumn = new DataGridColumn();



dgc.headertext=c...@name.tostring();

dgc.dataField=df.name();

var cols:Array =new Array()

cols.push(dgc)

partsGrid.columns = cols;

gridHbox.addChild(partsGrid)

partsGrid.addEventListener(ListEvent.ITEM_CLICK, itemClickEvent)

partsGrid.validateNow()// just to show you that I tried this but it
doesn't work.

}

[flexcoders] Re: Starting with Cairngorm or PureMvc

[normc_actionscript]

I found Cairngorm to be more straight-forward.
I knew little about Flex. I looked at the Cairgorm store example and it's 
pretty obvious.

I took a good look at PureMVC, but had trouble imagining how to set up the 
application I want to build. So I decided on Cairngorm. 

I suggest reading the Cairngorm Version 3 Beta documentation online for a 
conceptual understanding.

[flexcoders] Cairngorm store example - newbie binding question #2

[normc_actionscript]

Thank you Tracy for answering my previous question.

New one:
Why is 'handler' bound to 'confirmOrder' in this snippet?
 

confirmOrder is a function in the same file.
Is it just a way to set an initial value?

Thanks,
Norm
