Flash :: Efficiently Splicing Items From An Array Using Flex?
Aug 14, 2009
I have overcome a problem, but my solution seems really inefficient and clunky. Please consider this problem:
I have an array collection with articles in.
This array collection is filtered to a currently selected article category.
There is a cursor bound to a view that shows the current article. When a category is deleted I need to delete orphened articles, I can't use the cursor or collection without affecting the views as they are bound.

I am working on trying to collect data within an array (which works) and this data is collected when a button is pressed or selected. I also want the ability to remove an item from the array if the button is pressed again. Currently, I have these buttons dynamically generated and everything works well. The buttons have ids applied to them. SO what I am trying to get working is, if I select button 0, 2, 3 (0 indexing), the data array created holds [A., C., D.]. I want to remove A. after I click button 0. Instead, it seems to cause problems. What I am doing wrong with splicing??? trace statement:
A. items so far selected
selected items are: 0
A.,C. items so far selected

have an missileContainer array on the main timeline which I use to store the missile info in for collision detection. I use a for loop go to through the array every frame and check if it's hitting an asteroid. Everything there works fine, but in the missile's class I have a destroy function which removes the missile if it goes beyond the stage boundaries. However, I need to splice it from the missileContainer array on the main timeline, too. But I can't seem to access the missileContainer array from the class no matter what I try.

I have a browser-deployed Flash app (not an AIR app with access to SQLConnection) and it fetches JSON results from a remote server via HTTPService. I need to extract subsets from the returned resultset, an array of objects, efficiently. Mutltiple calls through the cloud to the back-end won't do. It all has to happen client-side.Is there any collection class in Flex ActionScript that can sort an array of objects by one of the properties the objects all have in common, like the Array sortOn method, and then also provides a binary search method can extract a subset of objects from the sorted version of the array without visiting every item in the array and comparing?if I have an array of objects and each object had a zip property and a name property, I'd like to be able to extract all objects with zip = 10015 from the a copy of the original array where the copy has been sorted on zip.

I have an app where a user puts in the required info into text inputs inside a titlewindow pop up and it sends the data entered into a datagrid. This first time when I call for the popup and enter info it works fine. Here's the problem: the next time I call the component pop up and click anywhere on the popup, including textInputs, the first the item in the array is automatically entered into the textInput where the user is supposed to enter the data themselves (BTW this textInput is also a autocomplete component).What I want is nothing to entered into textinput until the user inputs the data themselves. I've been tweaking with it for hours and im stumped. Here's the code: (this is main page)

I have an ArrayCollection of Objects. Each Object with three attributes:CustomerID, Income and DateMy goal is to chart this data for each customer (or a couple together) in a Income by Date LineChart display. Selection of customers is done with ArrayCollection filters.Data is fetched from an SQL database, however, each customer has some data points missing.f there was zero income on August 8, 2010 there will be no entry for that.Charting the ArrayCollection as is, is misleading because there is no indication of the missing data points.One way to solve this is to artificially add zero points for the missing dates for each customer. However, this would explode the data set (and impact performance).

I have an array of items that should be selected in my tree control. As you can see from my code below, I bind this array to the selectedIndices property of the tree. The selected Items are not properly selecting in tree(selecting some other items and always root is selected).Flex seems to "ignore" my items (selects some other indices).
My XMLList:-
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
<fx:XMLList id="XMLList">
<node><node name="max">

the AC is defined as follows:[Bindable] private var projectErrorsAC:ArrayCollection = new ArrayCollection;
I'm using this AC in a repeater to display each error. After each error is shown, I've placed an "Accept" and "Deny" button. Once the user clicks either one of these buttons, I'd like to call a function that removes the particular error from the AC. Here's what I have so far:

I would like to use the selectionMode=multiple described in the Flex docs, but with a few modifications:
1) I would like the box that the user drags over the graph to remain there until the user drags a new one.
2) In the top right corner of the box I want to display the sum of the items selected by that box.

I am trying to animate a navigation menu so that when you roll over an item (say "Contact Us"), it moves up a bit, and the rest of the items blur.
I allllmost have it working but there is one piece of code that is no longer working (blurTween.onMotionChanged) since I put it into a for each loop in order to go through the array and apply the blur filter to each item.
So my code is as follows:
Code:
import caurina.transitions.Tweener;
import flash.filters.BlurFilter;
import mx.transitions.Tween;

I'm creating a facebook application in flex. I'm actually working on the friends component that shows your friends who are using the application. now, each friend has a profile image.
I created the component using a s:List element.
In the Skin Class of the element i configured the requestedColumnCount to 3, which means it shows 3 friends. i added buttons to scroll left and right in the list.
Whenever I scroll to see a different friend, for a half of a second i see no image because the List component is loading the image in order to view it.
is there a way to make the list preload all the elements so i won't have this kind of problem ?

I have an array that holds a list of items. In a movie clip, I have that same list as the frame labels. I'm using a for loop to iterate through the array and then assigning event listeners so that when you roll over an icon, it sends the movie clip to the right frame label (matching the item in the array).
However, the code I have now only returns the first match and not any of the others. Here's my code:
Code:
for (var j:uint = 0; j<interiorCallouts.length; j++) {
featureTextArray[j].text = interiorCallouts[j];
featureArray.length = interiorCallouts.length;
[Code]....
See the showCallout function. I'm using the interiorCallouts array to match the frame label in the callouts_mc, but I'm only getting the first match. None of the others.

I have found a way! It's very complicated though... Hopefully someone has an idea on how to clean this up...
The workflow:
------------------
I'm using Flash to draw movieClips which are exported as one assets.swc file and then used in Flex for coding.
The scenario:
------------------
I've been working / thinking about this for the past 3 days.. it's driving me a little crazy. I've simplified my code down to 3 boxes that are drawn onto the screen. Each containing one background movieClip. The three boxes are three individual box clips in the Flash IDE library (different designs). But all three boxes share the same functionality.
The problem:
------------------
When using a custom baseclass (AbstractBox.as) to define all the functionality for the boxes, Flex looses all the code hinting for the movieClips inside the box movieClip (bg in our example) Also it seems like Interfacing doesn't work since as3 can't define MovieClip instances or any other variables in interfaces.
[code]...
Now my question: Why is this so complicated!? Isn't there a cleaner / simpler way to write this?

I am building a Flex application using Pure MVC pattern and Zend framework for calling php code on the server. I need to sync some data with my server which is using MySQL as the database. And there are 5 such tables I need to sync. So I call these php functions at regular intervals from Flex and use long polling on php side. The client side code for my subjects lies in 5 different proxies.
Should I send 5 separate requests from each proxy to call the php code which is lying in separate classes. Or should I build a separate proxy to send 1 request from 1 php file and then distribute this data among different proxies on the client side. Which one will be more effecient? Mathematics shows using separate proxies and php classes allow more number of users to be accomodated on the server.Can I write 1 SQL command to fetch data from all 5 tables given they cant be joined on any column?

I have a "menu" mc object which has 8 children with names "m1", "m2", and so on..... the last one is "m8" . They are NOT created dynamically.
the children are even organized in layers alphabetically.
