How to scroll Spark list with a disabled scroller bar? I created two buttons to scroll up and down, but it is unclear what methods can be used to scroll the list.
View 1 RepliesI have a spark List with an item renderer and a tile layout. If I scroll by clicking with the mouse on the scroll bar and trying to scroll with the mouse wheel after that, there is a problem: The interval of the scrolling is oversized, instead of scrolling one item down (or up) the List scrolls 4 items down (or up).
[Code]...
I'm using the following mxml code for displaying a list of some data. I built a custom renderer which can have variable height. Each time a new data arrives, the scroller should go to the end of the list. I registered to the events which triggers an array change.
It's working fine if the height of items is the same. But if this is not happening, the scroller is going a little bit above the end.
If the height of an item from the middle of the list is bigger, then the last items are not visible.
<s:Scroller width="100%" height="100%" id="scroller" horizontalScrollPolicy="off">
<s:DataGroup
id = "lstComments"

I have a spark.components.List component on which I would like the vertival scroll to be visible by default.
View 1 RepliesThe answer to my question is possibly easy, yet I haven't found an example of solving it in the web, nor have I found a solution reading ActionScript reference. My problem is the following: I have a big UIComponent derivate element inside a Scroller (spark.components.Scroller) window. The Scroller class is great because when my canvas element, that changes size dynamically, exceeds its boundaries, scrollbars appear automatically and handle scrolling of my UIComponent inside it. However, I'd like not just to be able to Scroll using these automatically appeared scroll bars, but also by using a pan tool that I will myself implement (similar to the hand tool in Adobe software, for example). The thing is that I am not able to modify correctly the element's position inside the Scroller window.
I tried, as a first approach, accessing to my elements' 'x' and 'y' properties, however, when changing them, I dont get the resulkts wanted. The code for it is the following (in which, for symplifying reasons, I used a text label as my 'inside' element, and two buttons as an external scroll controller, instead of a hand tool)

[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 an Application displaying a spark.List. Every item of my list must be visible (no vertical scroll).
I need my Application to be scrollable in a web browser, so I've add a Scroller containing all my components. When the browser window is too small to contain all my application, scrollBar appears.
My application looks like that :
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="100%" height="100%" >

When I scroll with my mouse cursor outside of the List, everythink works fine. When I scroll with my mouse cursor over the List, nothing happends.
It looks like the mousewheel event is stopped by the List, even if the List does not have a scrollbar.
I am working on a drag and drop feature for the sparkScroller. This is sort of how my layout looks:
<mx:Canvas>
<s:Scroller id="items" .. />
<mx:Box id="dummyRow" visible="false" />
<s:View id="touchView" visible="false" />
</mx:Canvas>
So when you hold your finger over a row in the items Scroller for more than a 30 seconds, the touchView becomes visible so does the dummyRow. The dummyRow gets populated to look like the row which you held your finger over.
So the touchView has the event handlers for moving your fingers and places the dummyRow where your finger is. The problem I am having is even though the touchView is reacting to my move events, the scroller still keeps reacting to my move events as well even though it's a sub layer. Because I started on the scroller it still keeps track!
How can I remove focus / tracking from the scroller?
I have a renderer that looks like this:

Loading thumbnails using this method works perfectly. The issue happens when you scroll the List.
are there any events that the scroller will dispatch when being scrolled?

View 2 RepliesI'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.

View 1 RepliesHere is a snip from within my code:
[Code]...
The 'recommendations' dataProvider is an ArrayCollection of String, which are generally sentences about as long as this one. By setting the variableRowHeight and wordWrap properties as shown, if a sentence is too long to fit on a single line, everything works fine- the row expands and the messages show on two lines, or occasionally three.
The space allocated for this panel within the entire canvas means if the total text size of 'recommendations' exceeds six lines, I need for the entire list scroll. This is also working just fine. The trouble is when using the mouse wheel to do the scrolling- Flex scrolls both the entire list and the single item where the mouse is hovering. Often this results in only the second half of a sentence being visible. Non-programmer friends I have asked to look at this noticed this, and tell me it as a problem. If a user does not notice the dual scrolling, and sees only a fragment of a sentence, it will be perceived as an error in the application.

I am using a scroller component within a custom skin for a SkinnableDataContainer. I am running into an issue in that the thumbbar of the scroller stops at about the 50% point, however this is actually the end of the scrollable area. In actuality, the thumbbar should be at the bottom of the scroll track. Here's the code for the scroller:
<s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/halo" bottom="150" >

View 1 RepliesI 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 RepliesI have several horizontal scrolling lists with differing item widths stacked inside a Vertical Group. On an item click all any selected item from the other lists will be cleared. When any of the lists are scrolled all the other lists should scroll exactly the same amount in the same direction, simalar to [URL]
The synced scrolling is throwing an undefined error and has crashed the adl(it is a mobile app) on one occasion. This happens only when I add more than 2 synced scrolling lists via event listeners.
So my question is: Can anyone see why this errors or is there a better way to achieve this type of horizontal scrolling multi-list, possibly a really wide data-grid or group of buttons inside a scroller?

How can I make my datagrid have its first column fixed and scroll the reset horizontally and vertically?
View 1 RepliesI found this example [URL].. which works great but only if you have the focussable elements in a VGroup.
However I have a Form inside the VGroup which means that the focussable elements are in FormItems of the Form. The Form can't be added directly into the Scroller and doesn't have a layout property.
I could use form.getElementIndex(formItem) and then do some math using the formItem y position but that's very ugly. Anyone have an idea how to get this working in a clean way like the above example?
How 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. When im dragging an item and over the other list item, i want the target item to change the background coloer.Basically instead of showing the black line indicating that I will drop between elements, I want to see the target item highlight.
