I have a XML and it has an attribute option or combo box, parsing that i need to create components in my flex dynamically. Viatropos has given a wonderful code, but i am not able to execute it... can anyone produce it.
View 2 RepliesIsn't there some way to re-write the following code, such that I don't need a gigantic switch statement with every conceivable type? Also, if I can replace the switch statement with some way to dynamically create new controls, then I can make the code smaller, more direct, and don't have to anticipate the possibility of custom control types.Before:

I am created a dynamically adding a VBox, that contains two images. Into a Custom Component that is derived from UIComponent. The problem is the Vbox that contains the two image is only a really tiny size. I would like the VBox stretch to the size of the two images. This is how I am creating the Vbox....

View 2 RepliesFor my AIR based application I am trying to create a custom component based on canvas which has an image (as shown below).

As a work around, I am trying to add an creationComplete listener to the canvas in my custom component and used to give titleImage.source = this.path . keep changing the image or when the path of the image fetched using some async call.
im trying to figure out what is better for run-time, creating components in MXML or by SCRIPT?. I built an app that recieves data from a server without knowing how much data exactly. In worst case scenerio , ill need 10 LABELS and 2 DATAGROUPS.But i usually need something like 3 LABELS and 1 datagroup. what is better? creating all components in advance and than not include in layout the ones i dont need, or make some checks and then create only the components i need by script? I made some tests , but it wasnt really decisive, run-time was pretty much simillar.Im guessing it must be stated somewhere what is better. Does anyone have an answer for me?
View 1 RepliesI have a Flex application which references a separate MXML file as a template for a custom component. I create instances of the component dynamically several times in my program, but I need to get a handle that will allow me to modify that instance of the component as desired. I pass specific information to this component on instantiation using bindable public variables in the component's MXML file. I add it to my main program using addChild().
I want to update the component's progressbar as necessary and I want to remove it from the box to which I addChild'd it. What's the easiest/best way to get a variable that will give me predictable access to each component so I can easily manipulate the components as necessary? Some research suggests creationComplete, but I decided it was faster to just ask than to go through lots of different experiments and come up blank.
I have some simple function in Flex in which I would like to send one of my variables to all the components used in my app... The problem is that there is lots of components in my app, and I'm not sure how to reference to my component's id... Basically, is there an easier way to do this;
private function preloadStuff():void{
// populating of bulkLoader var
var preloaderItemsList:XMLListCollection = new XMLListCollection(preloaderItems.children());
var item:XML;

I'm looking for a tool to create just the skins for different kinds of Flex 4 components.I'd like to be able to create the components myself and have the designer/artist do the skin, but I don't think they'd like the idea of doing them by writing MXML files.

I need to dynamically bind properties of components created at runtime. In this particular case please assume I need to use bindProperty. I don't quite understand why the following simplistic test is failing (see code). When I click the button, the label text does not change.
I realize that there are simpler ways to go about this particular example using traditional non-dynamic binding, but I need to understand it in terms of using bindProperty.

I've a custom component where I do some graphics (e.g draw a line) and dynamically add a subcomponent (e.g a label) to it.
If I base the component off Group (which is recommended as per docs since its a spark component) then when I dynamically add a label the graphics part disappears.
However if I base it off Canvas this doesn't happen.
Why is that the case?
Here is the code.

public class MyComponent extends Group

Is there any opensourse, free set of components for creating Flex mxml graphs? like aviary Peacock style ones with at least Drag, drop, and connect generators so each graph element could have or something like that. Framework should be opensource (like GPL, LGPL etc) BTW: I found one wary bacic made by Erno Aapa with Degrafa but I would really love to see something much more Flex 4 - mxml oriented and frienfdly.
View 2 RepliesI need to load all images that I have used in my project externally without embedding. The images are present either in skins or as icons for items in trees. I came across the IconUtility class here I was able to modify it and use it for trees but the problem is we cannot use iconutility for the same component to set 2 different skins (like for a button - upskin downskin). I was not able to think of a workaround with iconutility. Is it possible to simulate embed and create a class dynamically and return the class at runtime?
View 2 Repliesi'm loading several sound files, and want to error check each load. however, instead programming each one with their own complete/error functions, i would like them to all use the same complete/error handler functions.
a successfully loaded sound should create a new sound channel variable, while an unsuccessfully loaded sound will produce a simple trace with the name of the sound that failed to load. however, in order to do this, i need to dynamically create variables, which i haven't yet figured out how to do.
here's my code for my complete and error functions:
function soundLoadedOK(e:Event):void
{
//EX: Sound named "explosion" will create Sound Channel named "explosionChannel"
var String(e.currentTarget.name + "Channel"):SoundChannel = new SoundChannel();

something like

but what i wrote above dosn't work for some reason.
1) Using datefield as item renderer in flex.I am dynamically creating datagrid and its columns. like
dataGridColumn=new DataGridColumn();
dataGridColumn.dataField="invoiceDTO.invoiceDate";// I read this value from XML
dataGridColumn.editorDataField="selectedDate";
dataGridColumn.itemRenderer=new ClassFactory(DateFieldRenderer);
dataGridColumn.rendererIsEditor=true;
But when UI is generated i get the error invoiceDTO.invoiceDate not found on the TestDTO
//Test DTO
public class TestDTO
{
public var invoiceDTO:InvoiceDTO;
}
My objective is my dataField should be binded with datafield inside the datagrid.How can i do it in actionscript
2) I need to present combobox as item renderer. (same like case 1). But how can i assign dataprovider in the combobox which is present inside the datagrid.
I need a List that resizes to exactly fit its content, unless that height exceeds its (dynamically sized) parent container. My requirements are as follows:
The component extends List, or at least acts similarly. variableRowHeight and wordWrap both equal to true. The height of the list cannot be less than minHeight (roughly 32px for scrollbar arrows). The height of the list cannot be greater than the height of the parent container .
Note that the parent container can be resized dynamically.
The height of the list should be updated as the size of both the contents and parent container changes.
Live updating would be preferable but not necessary.
There should be no scrollbars if the content height is less than the parent container height (sounds obvious, but I've had trouble with this too).
The trouble is that with variableRowHeight and wordWrap, it's very hard to know the size of the content at any given time. If the parent container's width is reduced, a line wrap may occur in the list which will change the height of the content. I know I can measure the height of the list content using measureHeightOfItems() + viewMetrics.top + viewMetrics.bottom, but when should I calculate that? What events should I listen for? And the thing I've had the most trouble with - when should I calculate it to set the size initially (i.e. just as the content has finished populating)?
Do you know any flex component with the functionality such as horizontally collapsible window or panel I found arc90, but it folds vertically.
