I'm using a spark list to render data which I get from a web service.is there an event which fires after the list has finished rendering all the data ?I want to show a loading image to the user until the list finishes.
View 2 RepliesI have a child component that dispatches an event in Parent. The event in parent makes a call to our database. Right now, the event gets fired off & the child continues without the results. How do I make it so that the child waits for the results from the database b/f the child continues?
in child:
<fx:Script>
<![CDATA[
dispatchEvent(new Event("getDBcontents")); //
dispatch the event in the parent do some more stuff here but we need pause until we get the result from the parent

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'm working on an mp3 player. I want to trigger an event when the track finishes playing. I've created a function that will just trace a statement so that I know the event listener is working, but I can't seem to get it to trigger. Here is the playSong function in which the code is used:
Code:
function playSong(mySong:Number):void {
var myURL = my_songs[mySong].@URL;
playingTra = mySong;
current_song = mySong;
my_sound = new Sound();
[Code] .....
I tried to add in the following lines, but that instead institutes some playback issues:
Code:
if (my_channel){
my_channel.stop();
my_channel.removeEventListener(Event.SOUND_COMPLETE, stuff);
}
I'm using the Actionscript Timer class. What happens if I run a function every 3 seconds, but the function takes 4 seconds to complete? Does the Timer object queue up events? I guess this must happen if only 1 thread is being used?
View 1 RepliesIt seems to be the case that the MOTION_FINISH event fires of prematurely in the Flash Tween class. I've heard that it is not the best tween engine to use, but this seems like a particularly egregious. I am using "Strong.easeOut" for the motion. What are some alternative tween engines that people like?

//Where myDataArray is an ArrayCollection consisting of my Custom ValueObjects. When i execute the code it displays my list with custom item renderer, which is fine. But when bring my mouse over it, it doesn't give any colour highlight which means it is not selecting. Secondly, when i click on any of the list item, it doesn't dispatch any change event. I tried a lot but couldn't understand it.
I have a List component that has drop-in CheckBox itemEditor that also serves as the itemRenderer. It displays each item as a simple CheckBox with a label.
However, the itemEditEnd Event does not get triggered until I click on something outside of the List. I want it triggered once the CheckBox is checked or unchecked.
I was thinking of manually dispatching the ListEvent.ITEM_EDIT_END in a CLICK Event handler, but then the itemEditEnd Event would get dispatched twice. There's gotta be a better way to do this.
I have a flash project that's implementing a simple two player game. I have added an enterFrame function to my main movie which listens for keyboard activity in order to move a cowboy gunslinger. Whenever the cowboy moves, I send a message over a socket to a server which dispatches the movement to the other connected client. This works pretty well, however, the movement messages tend to arrive in clumps which results in jumpy animation of my cowboy on my opponents screen and jumpy animation of his cowboy on my screen. To illustrate, i put a trace in my enterFrame function because I am imagining that this function will run roughly once each time my main movie renders the screen. I also put a trace statement in my function that responds to network traffic and moves the remote player's cowboy on my screen. Here's the output:

The video seeks normally when first playing but when it finishes i canīt seek the video again. I used a listener to call a function after the event TimeEvent.COMPLETE occurs(video finishes). In the function i call the function player.seek(20) for example but it doesnīt work. The video keeps in the end of it.
View 1 RepliesI'm using flex 4.1 to write an application. i read in the documents that has the rowCount property to set how many items to display. the does not have that property. how can I limit the list to display 3 items ?
View 3 RepliesI'm using a lineseries chart, but it gets fairly slow to re-render when I add a new point when the total # of points is ~1200 points. Granted, this is running on a fairly slow PC (~600 MHz). Reading the Flex documentation on how to speed up rendering (turning off dropshadows, turning off filterData, etc...) doesnt seem to help. I bound my chart to an ArrayCollection (rather than the array I used before which I manually updated) and it doesnt seem to be any faster. Adobe's documentation seems to have me believe that the Chart looks only at what changed since the last time it was updated, but i'm only adding one point!
If their info is correct, why does it take significantly longer (5 seconds) to update one point when I have ~1200 points then when I only have 2 points (instantaneous)? FYI - When I add a new point to my ArrayCollection, I have to do a "AC.refresh()" to get the DataBinding to pick up the new data.
Has anyone seen rendering glitches with Papervision?

View 3 RepliesI have a component that has a sub-component they both use a shared variable from the model. The shared variable needs to be set by the parent component before it can be used by the child component. I did like this in the parent component:
<mx:Canvas
xmlns:mx="library://ns.adobe.com/flex/mx"
...
creationComplete="group1_completeHandler(event)" >
[Code]....
But for some reason when the code inside myCustomComponent tries to use myVariable for the first time I get a "null" object error. This means I guess that the child component gets rendered before the group1_activateHandler gets called and consequently myVariable gets set.
What should I do to ensure that the parent container initializes the variable before the child component gets created?
I need to have custom rendering of each row in my datagrid. It is column based by default. Is there some way to achieve this?
View 1 RepliesI'm currently upgrading an app from Flex 4.1 to 4.5.We've noticed that the Arial font is rendered differently between the two versions when used at small sizes.Here's a simple app example:
<?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"[code]....
When run against the 2 different sdks, here's an image of the font rendering we get:
Note that in 4.5 the font looks slightly squashed.
What's the cause of this, and how do we resolve it?
Here is a snip from within my 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.

When a user selects a category from the first drop down box then i want the 2nd drop down to be updated based on the selection of the first drop down. I have created multiple ArrayCollections whose names are set to the "data" values of the first drop down, for instance:
[Bindable]
public var countries:ArrayCollection = new ArrayCollection([
{label:"USA",data:"USA"},

I am currently working on a project in Flex and I am having a hard time having a list's contents ALL be selected by default. Wondering how to do this.

View 1 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.
I have a TextInput control which has a search functionality for the people in the system.It works fine. All I need is to style it in such a way that, it will be having search image on the right, which when clicked, will search. Its actually for look and feel part of the application, which will make the search box look much better.
It is exactly similar behavior implemented in search box embedded in Firefox.
i have a datagrid which contains a number of itemrenderers, it is populated each time a user does a search. Is there an event which can tell me when the datagrid has completed rendering all new rows and item renderers?
I need to trigger an event once everything has been created so that i can resize then container which holds the grid.
Currently im using DataGridEvent.HEADER_RELEASE and CollectionEvent.COLLECTION_CHANGE events to manage this however the problem with these events is that they get called as each new row is being added to the datagrid.

I have an mx:TileList which is bound to an ArrayCollection.I have some code that displays a "Loading..." message before modifying the ArracyCollection and some code after that hides the loading message.For small data sets, it works fine. However, I noticed with an array size of about 50~ and larger, flex will hide my loading message before the TileList is finished rendering the new data and I'm left with a blank screen for an odd second.Is there an event I can listen to that is called after the TileList is finished re-rendering? Code looks something like this:
loading_message.visible = true;
for each (var x:Object in new_data) {
tile_list_data.append(x); // bound to my_tile_list component[code]..........
In this example, loading_message appear, disappear, and then the flex app will lag before finally revealing the updated TileList.
The dataProvider for my grid contains several objects. Some of which have a Number value, and some Boolean values under field 'value' (other fields are used in other columns).I would like to be able to render differently for each data-type, i.e. have a checkBox for booleans, and a label for numbers. Furthermore, I would like to be able to edit these fields differently, unchecking the checkbox for booleans, and using a numericStepper for Numbers.
Just FYI, I decided to go with AdvancedDataGrid, to take advantage of the styleFunction property, nothing more..Tried to used spark-states, which didn't seem to work as I'm using an AdvancedDataGrid. I'm not sure what the problem was.
