how to explain this behavior but I'll try. I am loading images from an external url that requires basic auth so I am using URLLoader to load the image from a unique ID. The ID gets passed to the itemrenderer which then proceeds to load the image. But the images switch around on their own when I scroll. If I load more than 7 images or so it starts repeating images....

I'm running into an odd issue with itemRenderers inside a TileList.Here is a working example without an itemRenderer: 152.org/flex/
Here is the broken version with an itemRenderer: 152.org/brokenExample/. (I don't have the rep to make both of these a link)Both examples have "View Source" enabled.To see the problem use the broken example, select an album and scroll down one row. Scroll back up and the images will be switched.If you try this on the working example it's fine.This seems to be a widely known bug, but I can't find a solution for it.
UPDATE: I started playing with this example again and found out something else. Turns out you don't have to override the data setter. You can create a new method in the itemRenderer that is set whenever the tile wants to refresh. So the trick is to not rely on the initialize or creationComplete methods.This is what I have for the itemRenderer in the Application.
<itemRenderers:ImageTile img="{data}"/>
This is the code I have in the itemRenderer.
public function set img(value:String) : void {
trace("setting source: " + value);
this.source = value;[code]....
I updated my example to reflex this change.
Which parameter should I put not to automatically resize an Image that is put on an ItemRenderer?
Ex (in which the image gets resized):
<mx:AdvancedDataGridColumn headerText="estado" dataField="estado" width="30"
editable="false" resizable="false">
<mx:itemRenderer>
[Code].....
in datagrid I have an ItemRenderer (which extends UIComponent) which loads images based on a data value, eg:
_img.source = "assets/images/flags/" + value[dglistData.dataField] + ".gif";
When I run my application the images (flags) are appearing in the ItemRenderer. When I build and deploy the application into BlazeDS as an SWF file - the images do not appear. Instead there is the standard "missing icon" link that appears in Internet explorer.
As far as I can tell, my ANT build script includes the above directory "assets/images/flags/" and all the images into the SWF file.
I am trying to loop through a list of images and then add them to list box with a itemRenderer
public function createDataProvider():ArrayList
{
var a:Array = new Array();
[code].....
I currently have an SWF that is reading and displaying text, images and an ID number via an XML file. What I wanted to do was switch the text and graphic based on a URL.
For example the if the url was www.somedomain.com/about/ the SWF would then read the XML file and see that based on the domain ID the "about" text and images would load.
Here is what my Actionscript looks like
Code:
function loadXML(loaded) {
if (loaded) {
_root.headers = this.firstChild.childNodes[0].childNodes[1].firstChild.nodeValue;
[Code].....
we are making an app that uses a lot of images. Is it possible to preload all the images at the start of the app ? So the user doesn't have to wait in beteen switching the images.
View 3 RepliesI have a swf that loads images from my server and resizes them to fit the 800x600 stage size. The original images are stored at 1024x768 max pixels. The user can press a button to go into fullscreen mode. What should I do to show the images at the best quality?
a) should I resize the loaded images to their max size (1024x768).
b) do I need to reload the entire image if it has been resized to 800x600 or is the original image still accessible and I can replace the 800x600 image with the original?
I am using AS2 and Flash 8 (but require users to have Flash Player 10 for fullscreen)

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.
View 1 RepliesI have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
Suppose I have one combo box and I am switching its data provider from oldDataProvider to newDataProvider with ActionScript. Both data providers are ArrayCollections. Then, when a change occurs in the oldDataProvider ArrayCollection, it affects the combo box, although it is not its data provider anymore. Specifically, when removing an item from oldDataProvider (in the range of the newDataProvider values), it decreases the selectedIndex value of the combo box by one, changing the selected item.
View 1 RepliesI want to create a list of progress bars and update the list accordingly.I have group data in an Array as
<mx:Array id="arr">
<mx:Object label="Group One" min="0" max="200" currentValue="60" />
<mx:Object label="Group Two" min="0" max="300" currentValue="50" />[code]....
The values in the array object indicate name of group,minimum,maximum and current value for the group (to be used in progressbar).I used the list with "mx.controls.ProgressBar" as itemRenderer as
<mx:List width="100%" dataProvider="{arr}"
itemRenderer="mx.controls.ProgressBar"/>
Now what I need is whenever currentValue field of Array "arr" changes i want to update the progressbar "progress" value to currentValue (where min and maximum value of progressbar are stored in Array "arr").
Is there a easy / good way of getting the url from the URLLoader object? It seems at least two other people (this guy and this this guy) have wondered the same thing. Maybe we can get an answer here on s.o.?
View 2 RepliesI have a email form in a custom component that is put in the main application when switching to the email state. When someone searches something it will switch back to the search state. But when the person eventually goes back to the email state the contents of the form is still there. I tried doing a creationComplete and running a function that makes the fields have no text such as email.text = ""; but this doesnt work.
View 1 RepliesHow can we navigate within an itemRenderer? For example, in Views we use the View.navigator (ViewNavigator) to push and pop views, there is no such feature in ItemRenderer.

I have a List which has TextInput as itemRenderers for all its items. Upon application launch the items are rendered in the TextInputs correctly. The data is being populated from an Array of Objects.
What I want is, after the data has been populated in the ItemRenderers, I want to have an additional item renderer (TextInput of course)...so that if the user wants to enter another item, he can put it in the additional textInput.
And I also want to add the additional itemRenderer each time the user has added a new item and taps ENTER on the newly added item.
Below is my itemRenderer, there is the clearTxt_enterHandler handler..but I wonder how to add another itemRenderer upon "Enter".

In Flex 4 (beta 2), I have a list control populated from an XMLListCollection. What I would like to do is when an item is selected in the list, use a custom item renderer on the selected item as well as the item that appears just prior to the selected item in the list.
I am using a spark list control, but I am open to alternate components if the solution makes sense.Here is the strucutre of the xml used to populate the XMLListCollection

I have an AC with several questions and assoicated answers. These must be shown in a DG, and the idea is that the rows and colums of the DG are bound to the AC. For example, if the answer to question1 is Yes, the Yes-button must be true, and both the others must be false (as in normal radiobuttongroup behaviour). But when I change a button by clicking it, the actions datafield of the AC should change accordingly. Am I clear enough here?

What is the Difference between ItemRenderer and ItemEditor?And When ItemRenderer is initializing and loading?
View 1 RepliesI've created a custom ItemRenderer extending UIComponent and implementing IListItemRenderer. This renderer contains a Text-Object to display the value.
For editing I'm using the standard ItemEditor (TextInput).
Now, when I want to edit a value, I click on a cell and the editor is created. But instead of displaying the value which was displayed in the renderer, "[object Object]" is displayed.

I have a advanceddatagrid that has around 15 columns. Some are string, some are numbers. I have shown 4 columns below.
