I'm building a mobile app, using spark list control. When user tap on a list item, i want it to navigate to that correspondence page
<s:List id="list" width="100%" height="100%" labelField=" label">
<s:dataProvider>
<s:ArrayList>
[Code].....
how do i code it so that when user tap on item label="Page One" it will navigate to PageOneView.mxml and if it tap on "Page Two" it will go to PageTwoView.mxml and so on.
Flex 3 List control had a itemRollOver event. Flex 4 List doesn't have it. Is there an equivalent or a workaround for this issue?
View 2 RepliesI have a s:List where I've defined my own itemRenderer, and would like to insert a horizontal line separating items, similar to the way the mx:LinkBar works. I don't want to have a line at the top or bottom of the list, so I can't just include an upper or lower border in the itemRenderer. I was hoping the itemRenderer could be made aware of its index in the list, but I don't see how.

I'm trying to animate a list as I delete the top row. All the examples I can find use itemsChangeEffect to bind to the effect, but this property exists only in MX lists, not spark lists.
Any idea how I can get the same effect done in Spark Lists?
I'm trying to remove the top most item in the list with a slight fade out effect before the rest of the items move up to replace the gap.
I have a Spark List with a data provider consisting of a list of filled out form applications. What is the best way to add a button to each List Item (form application)? This button will be named Open and will navigate to the specified form application.
View 2 RepliesHow to enumerate items of Spark List component after setting dataProvider property?
I mean accessing them as DisplayObject instances.
I have a spark list, which is based on a dataProvider. As the application runs, the data in the dataprovider can change, and also the dataProvider can be swapped for a different one
What I need to do is make sure that something is always selected in the list (unless it is empty)
I have two spark lists and want to drag items from one list to the other.

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.

View 2 RepliesI'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component.
I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class:
<s:Label color="{data.color}" text="{data.label}"/>
Where data.color would be set whenever the user gives an answer to a question.
Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example).
[code]I want to extend the list with hyperlinks. For example in every node I should have an href attribute also. Then I need to redirect users to the selected item. I know Flash has the URLRequest class. The little problem I have now is to get the selected item. It propably is because of the dataprovider is xml and I haven't done the correct casting.
View 2 RepliesI'm developing a Calendar application, and I'm using a Spark List inside a Panel for each individual day, in a 5x7 grid. I'd like to make sure that the individual lists stay the same size and simply add scrollbars when needed, but I'd also like to avoid setting an explicit width or height to maintain compatibility with multiple screen resolutions.
View 1 Replies[code]When I hover the upper (red) part of the List (I would like to have the List scroll downward, the higher the mouse position is, the faster it should scroll). Similarly, If the mouse hovers over the bottom (red) part, the List scrolls upwards, and the lower the mouse is hovered, the faster the list would scroll. The current code does work - Though, the trace outs make it obvious that:this.layout.verticalScrollPosition += (mouseY - 220)*0.5.or this.layout.verticalScrollPosition += (mouseY -86)*0.5;are giving jumping effects, is there a way to make these values change more linearly or smoother? I created an AnimateProperty, but that works well only if I would like to scroll to a selectedIndex, In this case, I would like the scroller to keep scrolling linearly as the mouse is hovered to a particular red area, and increase in speed when I scroll to either extremity.The Objective: While the mouse is over the Bottom (red part )of the List, the verticalScrollPosition scrolls faster as it gets farther than the center of the ticket list... yet there is jumping effect going on, I suppose due to the EnterFrame. the Same with Upper Part... the higher the cursor is, the faster the List should scroll.I feel this is a common problem to Flash CSx developers.
View 1 RepliesI have a Spark.List with several items ("folders") each containing an ArrayList of files inside, when I select one of these "folders" it should display the list of "files" on another Spark.List. Its working right now by doing this:
private function onFolderChange (event:*):void {
var list:List = event.currentTarget as List;
if (list.selectedIndex != -1) {
currentFolder = null;
currentFolder = list.selectedItem;
fileListDataProvider = currentFolder.files;
fileList.selectedIndex = -1;
}}
The problem is that when the "file" thumbnails cover more then the List viewport and a scroll is needed sometimes by changing from a "folder" to another "folder" the file List loses files. For example lets say there is a "Folder 1" with 30 "files" in it (10 visible and 20 hidden by the scroller) and "Folder 2" has 5 "files" (all visible), if I switch back and forth between "folders" sometimes it will display everything right. Sometimes it will display a scroll on "Folder 2" when there is no need and sometimes it will only display a few (5 or 10) "files" in "Folder 1" even though it has 30. Something is wrong with the fileList, its updating its items but not really updating well. I've tried setting the itemRenderer to null and reapplying, setting the dataProvider to null and reapplying, doing validateNow().
I need to create a slideshow using data received from another view.I'm calling the slideshow's view like this:

I have a list with custom item renderers. What I would like is when one of the list items is selected to position another control OUTSIDE the list to the same vertical position as the selected item.
View 2 RepliesI want my list control has its content height as I don't want scroll bars. For the scrolling purpose I have my own scroller in parent container.
Now, The problem is when list control exceeds the maxHeight 10000, then it will start clipping remaining data. I think the solution is increase the maxheight.
how I can set maxheight more than 10000.
For Example..
</s:Scroller width="100%" height="100%">
</s:VGroup>
<s:List id="myList" dataProvider="arrData" useVirtualLayout="false" />
</s:VGroup>
</s:Scroller>
In this case assume that I have arrData.length = 9999999, and for that mylist's height will become 10000+ (Lets assume 15000). now mylist will clipped after 10000px height or list's vertical scrollbar will visible and as I adready have scroller of my own It will have two scrollbars at that particular time.
how in Flex can I display a message within a Spark List component that states that the List is empty. For example if I have a List showing number of jobs outstanding, if my List is empty then I want a message displayed across the List stating "there are no jobs to perform".
I'd rather not use an Item Renderer because then it's an Item (the list is not empty) and the item can be selected.
I have a regular spark list which is sorted correctly when no item renderer is used. However, when the following item renderer is used, the list shuffles and displays items from previous instances of the list.[code]
View 2 RepliesIn flex 4.5, I have an application that has a BorderContainer that loads a spark list (mxml style - _myList and the borderContainer is stored in a library outside of the parent application) that loads an arrayCollection with an itemRenderer (I should note said itemRenderer is not an inline renderer - on selection of an item in the list, the itemRenderer expands, loads a particular control within the item renderer based on data passed from the selected item in the list) and allows the user to perform a search. This works all well and good on startup/load, until I try to change the dataProvider for the list (my app allows users to switch data sources which then creates a new dataProvider with new variables).
