Flex :: Spark List Mouse Wheel Scroll Speed?

Flex :: Spark List Scrolling By Mouse Position

Mar 13, 2011

[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.

Flex :: Add Separator Between Items In A Spark List Control?

May 21, 2010

I 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.

Flash :: Flex Spark List Scroll To Bottom When New Data Is Added

Oct 6, 2010

I have a Spark List (spark.components.List) backed by an ArrayCollection for its dataProvider. The List has a vertical scrollbar when there's too many rows to display. What I want is when a new row is added to the List for it to scroll to the bottom to show that new row.

I've tried calling List's ensureIndexIsVisible from a listener on the ArrayCollection. This doesn't work because the List hasn't yet fully rendered the new row. It will either scroll to the second from the last row, or throw the exception:

Flex :: Spark List Have Something Similar To ItemsChangeEffect In Mx List?

Jun 28, 2010

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.

Flash :: EnsureIndexIsVisible(), Scroll To The Top Of A List Control?

Feb 27, 2011

I'm using FB4 and apparently I need to use ensureIndexIsVisible() to scroll to specific item in my s:List. Anyway, the code below successfully scrolls to the item but does not scroll it to the top of the list (it's at the bottom, and cut off somewhat).

MXML:

<s:List id="Schedule" dataProvider="{schedule}" creationComplete="creationCompleteHandler(event)"/>

AS3:

protected function creationCompleteHandler(event:Event):void {
var d:Date = new Date();
var today:String = String((d.month + 1) + "/" + d.date + "/" + d.fullYear);

Flex :: 3: Scrolling Of List Items With In A List Via Scroll Wheel

Dec 31, 2009

Here 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.

Flex :: 4 - Scroll Flex Spark Datagroup To Maximum Amount Programmatically

Jul 6, 2011

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):

Flex :: How To Add Spark List Item Custom Properties

Jan 3, 2011

I'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).
