Flex :: Itemrenderer - Image Switching Place In Tilelist?
Oct 26, 2009I'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.

View 1 RepliesFlex - PopUpButton With TileList And Custom Renderer?
Jul 25, 2010I have prepared a simple test case for a PopUpButton opening a TileList with black and red entries and it mostly works, but has 2 annoyances. I've searched a lot, tried several variants (added [Bindable] members in my renderer; added color member to the bids array; created my public override set data() method; ...) and has been getting some answers too, but they are way too general.
1) Scrolling "tl2" right-left doesn't work well: the entries are displayed in a mix of red and black. I know the TileList reuses itemRenderer, but how do I fix the problem?
2) In debug-mode I get numerous warnings: warning: unable to bind to property 'label' on class 'Object' (class is not an IEventDispatcher)

Flex :: Custom ItemRenderer And Editor?

Flex :: Custom ItemRenderer Does Not Use Styles Specified
Mar 18, 2010I have a custom item renderer which I use for my DataGrid. The DataGrid has specified selectionColor, rollOverColor and themeColor. The Problem is that the custom item renderer, does ignore those colors, and doesn't give any Feedback...
I tried to add the lines:

setStyle("rollOverColor", 0xE1F5DE);

View 2 RepliesFlex :: RadioButton In Custom DataGridColumn ItemRenderer In AS3
Apr 30, 2010I have a datagrid that I want to add a column of radio button using AS3 (instead of mxml). I was able to do this with a custom itemRenderer.
var dgc:DataGridColumn = new DataGridColumn();
dgc.itemRenderer = new ClassFactory(com.mypackage.RadioBtnColumnItemRenderer);
In my RadioBtnColumnItemRenderer.mxml, I have a box with a radioButton... like so:
<?xml version="1.0" encoding="utf-8"?>
<mx:Box xmlns:mx="[URL]" horizontalAlign="center" verticalAlign="middle">
<mx:RadioButton id="btnRadio" groupName="btnRadioSelect"/>
</mx:Box>
When I run the application, the radio button shows up in the column as it should. However, I cannot select just ONE of the radio buttons. I am able to select all of them, but I don't want this... I want the ability to select one and then if I select another one, then the first one is unselected and the current one becomes selected (just like you would expect radio buttons to work).

Flex :: Get A Custom ItemRenderer To Scroll The DataGrid Rather Than Its Cell?
Jun 2, 2009I'm having an issue with a custom ItemRenderer I've written for a DataGrid. With this ItemRenderer, it's possible that the contents could exceed the width and height of the DataGrid cell - and when this happens, scroll bars appear, letting me scroll the individual cell.What I would like, however, is that when the contents of the cell are too large, the entire DataGrid scrolls, rather than the individual cells.
Now, when I set the custom ItemRenderer's horizontal and vertical scroll bar policies to "off", I get the vertical scrolling on the DataGrid that I want (the individual cells stretch to accommodate the full height of the contents) but I don't get any horizontal scrolling. Instead, any content too wide for the cell is clipped. Incidentally, setting the DataGrid's horizontal scroll bar policy to "on" has no effect, the scroll bar gutter is drawn, but nothing scrolls Is there a way to force the DataGrid to scroll horizontally when my custom ItemRenderer's contents are too wide for the cell?

Flex :: Cannot Access Constant Through ItemRenderer Using ParentDocument?

View 1 RepliesFlex :: Differentiate Between A Data Provider Update And A Itemrender Being Recycled When Using A Custom Itemrenderer In A DataGroup?
Oct 18, 2010How do I differentiate between a data provider update and a itemrender being recycled when using a custom itemrenderer in a DataGroup?I have overridden the set data function of the custom item renderer, but I have found that on making a change to the ArrayCollection used as the DataProvider some of the item renderers are not assigned the same object they had before the update. This has made it almost impossible for me to distinguish between a data update and an itemrender being recycled. Also, the data never seems to get set to a value = null, so that seems to be out as well.

Flex :: Setting A Custom ItemRenderer In A ComboBox On Specific List Items After Combobox Creation?
Nov 8, 2010I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..
I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.
