I have found something good here. [URL]..The mouseover effect on the list item is good. Any ideas to make this look.. I can infer that this is happening on mouseover of the Image Component. I think this is similar to google image search preview of images. If anyone have come across a component similar to this kindly share it to me and to all.

View 1 RepliesI'm creating a mobile app in which I need to show a calendar with months at the top. The months are part of a component that extends from SkinnableDataContainer (and has some custom scrolling/behaviour - which is why I did'nt use a spark list). I need the months to be shown as a 'trapezium' shaped tab and so I'm using a png image as a mask in the item renderer for the component.
When the mask is not applied, it all works well - the months render, the list/data container selection works when I click on a month and so on.When the mask is applied, it renders well, scrolling and everything else seems to work well - but when I click on a month, nothing happens visually. And from the trace statements in my code, it appears list item selection is not changing. Looks like mouse clicks are not working.
Code:
public class TopCalendarMonthRenderer extends LabelItemRenderer {
[Embed(source="/assets/trapezium_alpha.png")]
private static var TrapeziumMask:Class;
private static var trapeziumMaskInstance:BitmapAsset;

How do I wordwrap in a spark list w/ an itemrenderer? This posting at[URL] works 100% but when I try to set a separate item renderer, I can't get the word wrapping...instead, I get an ugly horizontal scroll bar. HEre is my mxml:

I have a List and the item renderer displays an image. Whenever you scroll the list, and the item renderer refreshes, it redownloads the image. Causing there to always be a delay. Is there some way of caching it so it doesn't have to redownload every time causing a delay in showing the image every time you scroll the list?
View 3 RepliesI 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.
View 1 RepliesWe have a requirement to show a list of appointment slots. So every hour of a schedule has a set of 10 min slots. The requirement is that if we click on a arrow button at the 8:00, 9:00 hour slot, the layout of the hour slots should change from a vertical list to a horizontal list.For this we modeled the system as follows:ScheduleComponent ->(contains) -> List (Hours of schedule)The HourViewComponent is an Item Renderer, that displays the 10 mins slots based on the available appointments by using a Slots List (list of slots in the 8:00 hour). For the Slots List we have a Slot View Component as an Item Renderer.Now the issue is that when we click on the 8:00 slot we are able to change the HourViewSlot from a VerticalState to a Horizontal state. But The container height is not collapsing in the minimized state. It occupies the same size as the vertical layout! We tried using variableRowHeight attribute.

When a button is pressed I want to access textArea2 and change font size.
I am trying to turn labels red when they can no longer be added to a list because of size requirements. The renderer works but Flex creates a separate component. I can't think of any good way to get that value to the new component.[code]

View 8 RepliesI have a list component and I have an item editor for the items in the list. I would like to have a button that the user clicks once they are done with their changes because I am having them edit multiple pieces of data in the editor and I would also like to validate the data before closing the editor as well. I just don't know what to do on the button's click event to make the item editor close and commit it's changes to the data provider.

View 1 RepliesI have an mx:tree with with TreeItemRenderer as below.
Parent1 (Delete | Rename)
Child1
Child2
Parent2 (Delete | Rename)
Child3
Child4
Delete and Rename are link buttons
Now when i click Rename a popUp should be shown like
OldName : Parent1(Text Input showning present Name)
Enter New Name: Parent1NewName(Text Input for entering New name)
OK | CANCEL Buttons
Afetr Entering the new name,click OK,popup should be closed and need to get the value in the treeItemRenderer.
I have the logic to rename the Parent1 in TreeItemRenderer and also I m able to get the Parent1 in the popup OldName TextInput.But after entering the new name i m not able to get that new name in the TreeItemRenderer.
I use a spark List with a custom item renderer and an ArrayCollection for dataProvider.
The ItemRenderer looks something like
<mx:TextInput id="txtValue1" text="{data.myFirstValue}"/>
<mx:TextInput id="txtValue2" text="{data.mySecondValue}"/>
However, even though I change the text in txtValue1 or txtValue2, those are not actually changed in the object inside the ArrayCollection.
myFirstValue and mySecondValue are decorated with the [Bindable] tag.
My understanding is that if the text property is set to be bound a certain property, the changes should be automatically applied.
So the HACK (or so I think) that I use is to listen to the focusOut event of each textbox, and access the parent data provider and set the the values manually.
Is it a bad idea to inject data into an itemrenderer. The reason I ask this is because the state of each item is dependent on different changing data sources. So the original data is used to just display a new item, but there could be two to three other data collections that would be needed to determine the item's behavior. Is there a better way to do this? Should I be creating a custom DataGroup with the other data sources as properties on this custom container and then reference the data sources from the itemrenderer to the parent?
