I have a datagroup where I use a custom itemRenderer with a datagrid inside. What I want is to access each datagroup's itemRenderer's datagrid and get it's dataProviderAll I know is that you can access the ItemRenderer by using myDataGroup.getElementAt(index)
View 1 RepliesI have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.

View 2 RepliesI have a component with a public variable declared
[Bindable]
public var mnuSource:String;
When I extend this component, I can reference mnuSource (it compiles) but Runtime complains about the property not being accessible (error 1056).
How do you modify / declare component properties so they are actually available to other components?
I have a spark skinnable component which contains a datagroup with images. The datagroup is scrolled by hovering the mouse over it. Everything works fine except one thing: after I change the datagroup provider, I need to scroll down automatically. The problem is the images are not loaded immediately after I set the provider so (contentHeight - height) does not yet represent the actual maximum scrolling position. Is there an easy way of telling the datagroup to scroll down as its content loads? Because the workaround seems to be not so straightforward. This is the code for scrolling(thumbnailStrip is my datagroup):

I have DataGroup with TileLayout. How to make datagroup resize accordingly to number of elements in datagroup?For example 1 have 1 row with 4 elements. Each element is 20 pixels tall. So I want my datagroup to be 20 pixels tall as well. If I have 7 elements which will be 2 rows I want my datagroup to be 40 pixels tall and so on.Right now for datagroup with 1 row is about 100px tall.
View 1 RepliesI'd like to have an overlay that draws lines between selected items in different Flex 4 List controls.
The problem is I can't figure out how to access the x, y coordinates of the list's item renderers.
I am currently working on a Photoshop-like transformer application to work with DisplayObjects as layers. I have an ArrayCollection which serves as my data provider for my List of values, but the problem is that the items are appearing in ascending order in the List:
0 - Item 1
1 - Item 2
2 - Item 3
3 - Item 4
Since it's a layer manager application, I need the items to appear in descending order like so:
3 - Item 4
2 - Item 3
1 - Item 2
0 - Item 1
This is because layer 0 is at the bottom of the stack, whereas layer 3 is at the top, rather than the other way around which is the way Flex is currently displaying things.
I know that I can simply apply a Sort to my ArrayCollection to cause the items to be sorted in reverse order, but this breaks functionality in my application. I was wondering if it would be possible to essentially modify my Spark List or DataGroup to have the layout render items backwards.
I've found a very annoying problem with the itemRenderers in a DataGroup in flex 4, when I mouseout of the itemRenderer is returns to its default state. Here's an example:
<s:Application

xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">

When the user clicks on the button the VGroup is collapsed as expected, but then if a user moves their mouse out of the item renderer it then collapses, i.e. returns to its default state.
I've been playing around with renderers the last few days for a mobile application. I'm creating a gridlike renderer that has columns that is light weight for a mobile app. It is a bit of a poor man's datagrid. The layout is fine. The question I have is controlling the height of each row in the list.
When measure() is called, I set the measuredHeight to:
measuredHeight = getElementPreferredHeight(ld) + verticalPadding;
Where vertical padding is:
var verticalPadding:Number = getStyle("paddingTop") + getStyle("paddingBottom");
When I debug on the desktop, the measuredHeight is set to 12 and on the device (Motorola Atrix), it is set to 12. But when layoutContents is called, the unscaledHeight is a number much larger than my measuredHeight value (44 on the device, 66 when running on the desktop), resulting in more vertical whitespace surrounding each item than I care to have. How do I control that row height? I happen to be using a Datagroup for this particular example but in some playing around I did with just a simple list, I had the same issue. Somewhere the system is overriding my measuredHeight with some other value.

View 4 RepliesHow 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.

I have some generic functions like copy, paste,etc in an AS file. I want to use them for editing data present in different mxml applications embedded in one application. If I pass the child's component id as a parameter of a function in one of the events, I get the value as either null or the parent app name.

This is the setup. I have created a timeline with a playhead. When my playhead is dragged I would like the timeline to scroll with the drag.
So far, the only way I can do this is by setting clipAndEnableScrolling to true. But in this case I lose the scrollbars(not to mention the impact on my view). So what I would like is to set this property to false and dynamically affect the horizontal scrollbar's position, in other words enable scrolling without the clipping.
How can I Access Items Selected in a Component from the Main App I've got a component that has a listControl and a couple of RadioButtonGroups. I need to access the selected items in the main application. What's the best/simplest way to create and access the array of selected items. So, the user clicks the button to confirm the selections and then I need to access those selections in the main app. Is there a way I can use a public var to build the array? Another idea?

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
