Hi, I've got a Tilelist and I'm using an ItemRenderer, which is a Button. I don't understand how to reference what was clicked. So, if the first tile (which is the first Obect) is clicked, how do I know that that particular one was clicked. <mx:ArrayCollection id="myAC"> <mx:Array> <mx:Object id="first" label="1" /> <mx:...

You can hook into the creation of Flex 4 item renderers easily enough (through itemRenderer, or itemRendererFunction) allowing you to pull renderers from a custom object pool, but how would you put those renderers back into the pool? I understand that layout virtualization does a form of object pooling, but I'd like a way to hook in to ...
Virtualized Layouts are nice, but I find that they often feel a bit "chunky" due to the "tightness" of the virtual range. This could be improved by increasing the range - one or two steps ahead (and behind) would often be enough to improve the "responsiveness" of the list, especially when external resources (like images) need to be loade...

Hi, 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 doe...
Hi, I have a custom component as an item renderer. In this renderer there is an item called dlFirstChoice. Now when I add more items to this list and force the list to rebuild itself something odd happens.

I have a ListView in ext-gwt and I'm adding some custom data to it. How can I set an item renderer on the ListView? As of right now, whenever an item is added, there's just a small line representing each entry in the view. Here's my basic code: import com.extjs.gxt.ui.client.store.ListStore; import com.extjs.gxt.ui.client.widget.Lis...
I need to create a Flex component similar to ComboCheck (by Arcadio Carballares). What I need is a ComboBox with CheckBox and TextInput instead of Checkbox's label. If CheckBox is selected the TextInput is enabled and editable, other way it's disabled. Do you have an idea of the easiest way to achieve it? ...
Hey, A combo box as an item renderer for a data cell in a Flex Datagrid has been demostrated at various blogs. What if that combo box has to have an external dataprovider that has to be set at the time of converting the renderer class to a ClassFactory. Can this be done? Or is there a workaround? Thanks in advance. ...
I have a Flex Spark List (well it's a Tree to be precise but it renders as a list) and as I'm scrolling through it I want to provide information about the item that is currently at the top of the list in context to the viewport. So this could be the 100th item in the list depending on how far you've scrolled down. ...

When I use a static ArrayCollection within my ItemRenderer, it works (please see listing 1). However, when I use Swiz to mediate a 'list complete' event to load the ArrayCollection, the dropdownlist does n...

All works fine so far but I want the TextArea in the first itemrenderer to receive focus so that it instantly becomes editable when tabbing onto the List. Is that possible and if how would I achieve this? I've alr...
