Flex :: Scrolling Interval In A Spark List With Tilelayout Oversized While Using Mouse Wheel After Scrolling With Mouseclick
Aug 27, 2010I 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).

Flex :: 3: Scrolling Of List Items With In A List Via Scroll Wheel
Dec 31, 2009Here 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 :: Scrolling Of List Control Is Misbehaving?
Dec 22, 2009I am having this very weird behavior with a mx:List control not scrolling properly.Here is a snippet:
<mx:List itemRenderer="customerRender" x="19" y="257" height="68" width="290" id="orderStatusHistoryList" color="#CCCCCC" rowHeight="35" ></mx:List>
The custom render creates a vBox that is 35 pixels high with some labels in it.Now, my dataProvider, set in the script block,is returning 3 items for the list (say item1, item2 and item3). Because of the height of the list control, only 2 are shown initially.Now for the weird part, when I scroll down the list to see the next item it is all messed up.
Initial display:
Item 1
Item 2
Display after clicking the scroll down button:
Item 2 (expected)
Item 1 (What the ?, this should be item 3)
Display after click the scroll down button one more time:
Item 1 (all wrong)
Now, if I increase the height of the list control,so it has enough room to display all three items, it displays fine.Also,I put a trace statement is the item render and flex is rendering all three items with the correct data.

View 2 RepliesScrolling A Sparks List With TileLayout In Flex 4.5?
Sep 1, 2011I'm experiencing a very strange behavior with a spark list with TileLayout placed inside a scroller. Basically, I want to have a title area above my list that scrolls away when the user scrolls down the list. To do this I put the title and the list inside a Group and wrapped the group inside a scroller with width and height = 100%. I also set the verticalScrollPolicy to off on the list to make sure everything scrolls together.
The problem is that if the list has the default VerticalLayout everything works fine but if you assign a TileLayout to the same list it only partially renders the items (about 30 items when testing on iPhone 4).
Here's the fully functioning code. Try it like this first, then try removing the <s:layout> part to confirm that it works well with VerticalLayout:

View 1 RepliesFlex :: 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.
View 1 RepliesFlash :: Detect When Flex Spark List's Data Has Changed
Oct 6, 2010I need to detect when a Flex Spark List (spark.components.List) data has changed so that I can programmatically change its scrollbar. I know that List is a an EventDispatcher but it's unclear which event I'd register for.
Edit: My List's dataProvider is an ArrayCollection that elements are added too. So the dataProvider is never replaced. I considered listening to the backing ArrayCollection, but it's possible the List will react to the change after my listener, which alters the scrollbar. Thus my listener's changes will be superseded by that of the List.
Flex :: Scrolling With The Mouse Wheel On An Application Containing A Spark List?
Mar 18, 2011I 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%" >
[Code]....
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.
Flex :: Keep A List From Scrolling On DataProvider Refresh/update/change?
Jun 30, 2011I have a simple list and a background refresh protocol.When the list is scrolled down, the refresh scrolls it back to the top. I want to stop this.I have tried catching the COLLECTION_CHANGE event and validateNow(); // try to get the component to reset to the new datalist.ensureIndexIsVisible(previousIndex); // actually, I search for the previous data id in the IList, but that's not importantThis fails because the list resets itself after the change).I hate to use a Timer, ENTER_FRAME, or callLater(), but I cannot seem to figure out a way.The only other alternatives I can see is sub-classing the List so it can catch the dataProviderChanged event the DataGroup in the skin is throwing.
View 4 RepliesFlex :: 4.5 : Strange Scrolling Behaviour In Custom Layout Used In A List
Sep 15, 2011I created a custom layout for a list, to be used on a mobile (android). I used this as example : [URL], using virtualization. Now the problem I have is with scrolling : when scrolling to the bottom of the list, there seems to be always a "bounce back", as if the list would have reached and as if the bounce/pull effect is taking place. But in fact the list has not reached the end at all, in fact I can not even scroll to the last element in the list. When going back from bottom to top, there's no problem at all.
I trace the top and bottom of the Scrolling Rectangle (Rectangle.getScrollRect) and there I can see that when scrolling down, the top and bottom parameters increase, but when releasing the touchscreen, all of a sudden the parameters decrease again with a certain amount, and so never reaching the end of the list.

ActionScript 3.0 :: Very Large Scrolling List Of Thumbnails?
Oct 10, 2008I have a photo browser that I am building, and so far itlooks good. It loads in however many images are listed in an XMLdocument to thumbnails, and then opens a larger window when youclick on them. The program basically stacks the thumbnails on topof one another in a movieClip, and you scroll through with a scrollbar or by dragging the thumbnails up and down directly. My issueis, once that movieClip gets to a certain size, Flash doesn't dealwith it well. Let's say I have 100 images I want to scroll through.If I stack them all up, and they are 150 pixels high with 25 pixelspadding each side, that's a 20,000 pixels high movieClip, and thatdoesn't fly. I thought about using a list component, but I need itto scroll smoothly, and not only a cell at a time.
Do folks have any ideas on how to do this? It's really keythat it scrolls smoothly, and that it can scroll by dragging photosdirectly up and down in the viewer. It's easy now because I canhave the dragging behavior attached to the thumbnail scroll, andnot each individual image, and I can move that one movieClip,rather than tracking the position of all the images

Jun 22, 2011I'm very novice at actionscript 3.0 so I can't handle custom components so I just use components given to me through flash professional. I want to scroll through a list by clicking down and moving mouse up and down (Almost like touchscreen model scrolling eg. iphone, andorid, ipad). I've tried startDrag() after adding EventhandlerI(ListEvent.ITEM_CLICK) to the list but it would start dragging the WHOLE list not through the data in the list. If my explanation isn't clear enough I'll be gladly be able to answer your question! So basically I dont want to see the scrollpanel skin on the right. If there is a way create this scrolling effect any way possible.

ActionScript 1/2 :: Scrolling Multiple Text Fields Via 1 Scroll Bar - Removing Commas From Being Displayed In Array List?
Oct 7, 2009I have been scripting this flash profile card which pulls data from multiple XML files. The problem i am having is when it comes down to pulling this 1 set of information which is accessing the attributes of an array of specific XML nodes on display after the first item it inputs a comma before each item.
My code:
---------------------------------------------------------------------- ---
xmlData = new XML ();xmlData.ignoreWhite = true;xmlData.onLoad = loadXML;xmlData.load ("../xml profiles/test.xml");
---------------------------------------------------------------------- ----
function loadXML (loaded){if (loaded){ xmlNode = this.firstChild;
[code].....
This is just a draft version of the layout i used to pull up fake data... to show the commas.Lastly i am wondering if it is possible to control the 3 text fields using 1 scroll bar or would i be better off learning how to create columns in 1 text field to display these lists.
Flex :: Spark List Have Something Similar To ItemsChangeEffect In Mx List?
