Flex :: Add Element To Top Of List?
Dec 15, 2011
I've got a spark list that gets dynamically filled.So far the new items appear at the bottom of the list. What I'd like to do is to add them at the top.The items in the list have a unique ID so some kind of sorting mechanism would probably do the trick as the new items have a greater ID than the old ones.What I'd like to avoid is some complex method behind this as I'm working on a mobile platform and the list can get quite big so I need this to be as efficient as possible.The list's data provider is an ArrayList that gets updated using binding.

I have a s:List in my flex application attached to an ArrayCollection ( elements ). I want to change position of one element, so in fact I'm changing it's item index, the question is, how to do this kind of action ?
Here is a better example :
item 1 i : 1
item 2 i : 2
item 3 i : 3
item 4 i : 4

Is there a way to query an embedded flash element to determine the available methods that can be executed on it via JavaScript?
Edit:
It appears that in IE it's as simple as
for ( i in flashNode ) {
alert(i);
}
After much clicking, they will be some of the very last members enumerated.
Still not able to determine this in Firefox though.

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.

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.

The traditional way to assign an icon would be to use the icon field of the item renderer,which reads the value of "icon" property in your data, for example:
listData.addItem({label: "Logout", icon: "com.classpth.DefualtThemeLogoutIconClass"});
But i want the DefualtThemeLogoutIconClass to changed to another class: ightThemeLogoutIconClass when the theme is changed.The only way to do this would be to use a style declaration containing a classReference to the icon, and change its the value in each of the CSS files of the various themes.The question is, is there any way to assign this style to an icon in a List, something as easy as intuitive as list[0].getIcon().setStyle("styleName");

I know that there is no such function as getElementByName in Flex but I also now that you can do this["object_id"] to get the element of the application u're in.What about getting an element inside another element?I've tried making element["id"] ? But in my try-catch it always runs the "catch" part..how do I get an element inside another element just having it's id in dynamically created string form?

I have flash where there is a link for song download. And, at the bottom of the flash I've a count, loaded thorugh flash vars which should increment everytime donload button is hit. Please let me know what approach should i take to do that. can i call a Java method on donload button which will insert a row in the table and and then get the count and render it to the count variable in my flash?
May be this extremely confusing. Here is a very similar example on how it is done. This is actually very similar to what i want to do. [URL] on this link there is count below which increments you hit the download button.

I've built a rather robust tooltip class recently that attaches and draws a single tooltip sprite to the root, then uses MOUSE_OVER to detect when it is over a tooltippable object, and shows the appropriate tooltip text. At the moment, I'm ensuring that any elements in my application which wants to take advantage of showing tooltips implement the ITooltippable interface, and expose a public getter, get tooltip().

Basically I have 14 text boxes, each box draws its content from an external txt file. Next to each text box is a button. I want the button to be either visible=true or visible=false depending on weather or not the text box has content or is "undefined" Here is what I have so far, and it's not working:[code] I would like a FOR loop to just run through the variables and check to see if any of them are undefined. if it is, then make the correct send button invisible.

In Flex Mobile I have a few buttons in the action bar. On devices with very small screen (such as the HTC Wildfire) not all buttons can be shown. Is there a way to tell Flex to hide an element when it doens't fit? I know it is possible by using states and test the width of the screen but I hope there is another way..

I have a simple list in Flex that is populated every N seconds by a dataprovider. My goal is to avoid scrolling the list after the dataprovider has been changed.
So, before I populate the list, I save the selectedIndex, and once the dataProvider is filled, I call:
list.selectedIndex = index;
list.scrollToIndex(index);
Trouble is that this moves the selected item of the list to the top. The solution would be to get the index of the first element displayed in the list: but I have no idea on how to get that.

How do I put things above an mx:HTML element? No matter where I place the code it's always under the <mx:HTML> element.
Example:

<mx:Label x="150" y="50" color="#ffffff" text="CAN YOU SEE ME?"/>

I'm trying to implement a dragging system which can only be described as similar to dragging the map on Google Maps. I can set up dragging easily in Flex, but unfortunately the standard model of dragging i.e. dragging an element proxy and dropping it in another element is not what I'm after.
Is there anything built into flex where the actual element rather than a proxy can be repositioned in a different place within the same parent? Or will I have to hand code something using mouse events as you would if implementing a solution in JavaScript?
