I have a question on coustom sort..I have a datagrid for which one coloum has a itemrenderer. I need to sort a coloum based on the value in the item renderer. In the dataprovider for the datagrid i have a numeric value. Based on the numeric value in dataprovider i have a String associated with that value which is shown in UI. I need to sort based on the statusLabel associated with the numeric value.
[Code]...
I have been working on sorting Arraycollection like ascending , descending the numeric list. Total length of my collection will go up to 100. Now I want to preform sort to nested data like this
Data Structure
Name : String
Categories : Array ["A","x or y or z","C"]
Categories array will have maximum 3 items , out of that three items the second item can have 3 different values either X or Y or Z. My result data looks like here
{"Mike" , ["A","x","C"]}
{"Tim" , ["A","y","C"]}
{"Bob" , ["A","x","C"]}[code]....
anyone please explain how to sort this type of data in a way showing all "x" first , "y" next and "z" at the last and vice a versa.

i got an Arraycollection which holds other arrays in it.i want to display the data inside with an item render but cant manage to do this
here is example code to explain my question
<s:DataGroup dataProvider="{news}"
itemRenderer="components.displaynews">
and this is the item render
<s:Label text="{data.??/}"/>
now what i dont understand is what comes after data? in the array collection the data goes like this : myArrayCollection->[0]->firstname
so when im binding data to item render,how do i represent the [x] to get to the specific name that i want? this obviusly wont work
<s:Label text="{data.[0].name/}"/>
and one more thing is what is the lightest way to display data in a listgroup with simple item render (image and text)
private function convertFBEventData2TreeData(eventData:Object):Object
{
var children:ArrayCollection = new ArrayCollection();[code].....
i dont know what to add after data, i tried many things but nothing work :
I have an ArrayCollection where I want to be able to bubble items up or down by one position. What is the best way to do this?
View 2 RepliesIn the project I'm working on, there are towers the user can place. However, it you place a tower higher then another one, it appears infront of that one, which looks weird.I want to be able to arrange all the towers so that that does not happen.There is an sprite called towerHolder holding, which all the towers are children of, and an array called towerArray, which the towers get pushed to when they are created.I tried clearing towerHolder, then running the sortOn() function on the array, and then adding each tower back to the towerHolder, but the towers just seem to be randomly placing themselves irrelevent to their height.Here's my code for the relevant parts:
Actionscript Code:
function clearTowers():void { while (towerHolder.numChildren > 0) { towerHolder.removeChildAt(0); }}function orderTowers():void { clearTowers();

View 3 RepliesIm busy with a rpg graphics engine, while discovering as3 whilst doing it. So I made different classes for the world, tile managers and players, etc. But since I have a 45 degrees SNES rpg view on my world I need depth sorting based on their Y coordinate. At least my npc's and the middle tile layer need that. But all these objects are now all different classes now and the swapchilderen method is quite cumbersome. Do I need a whole messy cumbersome method to sort specific tiles and npc's based on their y coordinate or is there a simpler method to have proper depth sorting in as3?

I've been playing around with ActionScript 3. They have a new way of placing clips onto the stage, "addChild(clip)," which automatically places the clip onto the stage with it's own depth. So here's my problem, when making a tile based game, I have to constantly depth sort to make sure the object lower on the screen has the higher depth than an object higher on the screen. Pretty much, their depth depended on their y-coord. Does ActionScript 3 still let us play with depths?
View 2 RepliesQuick Question, I just started learning the psuedo 3D methods in FP10, and as a sample I am creating a virtual rolodex. It is dynamically generated with a user inputted number of cards. The cards are then added to the stage and are rotated around a central axis using the function below.
[Code]....
After this is created I have an Enter Frame listener that rotates the cards around that axis based on mouse position. Problem is that they get depth sorted based on the order that they are created, cardArray[0] in back all the way up to whatever the number of cards is. I have tried a few of the simple Z sorting classes and noticed that my cards dont actually change there Z property, only their rotationX. I was just wondering if anyone might know of an easy way to depth sort these. Otherwise the best idea I can come up with is to check the rotation based on 360 degrees and assign a depth. That seems like a lot of ugly math though if you want to see what the swf looks like check here.
I'm having a hard time wrapping my head around this problem. I have 2 unsorted arrays that need to be compared, array2 must contain all elements of array1 and array2 can any number of extra elements without affecting the result. I don't see any benefits from sorting the arrays and comparing the string values as array2 can have extra information causing noise.

What I want is to sort a Vector array of objects(not primitive), based on a propery(Number). (think character.zDepth). Generally the same thing as the sortOn function of Arrays, except that we don't have that for Vectors.
like myArray.sortOn(x, Array.NUMERIC)
Dealing with Vector arrays of primitives not complex objects.
I am trying to sort big array using actionscript 3. The problem is that i have to use custom sorting function which is painfully slow and leads to flash plugin crash.
Below is a sample code for custom function used to sort array by length of its members:
[Code]...
I'm doing a project where I manually create sorting algorithms.After several tests I found out that my heapsort is way quicker than quicksort (I think it should be the other way around), my selection sort is also faster than insertion sort.I'm testing using integers from -100 to 100, randomly generated, 5000 values in an array (I modified this number several times, still the same problems).My quicksort isn't in-place.I thought that maybe flash's recursive functions are slow? my heapsort uses loops, unlike quicksort. That's just a hypothesis though. I start a timer, run the class's exec() function, stop the timer and calculate the elapsed time.[code]
View 3 RepliesI'm trying to create a custom sort function. This function will sort the pegs in a certain row by their row number (0: lowest -- numRows - 1: highest)For context, here is Adobe's description for the Array sort method: http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/Array.html#sort()
My array-building function:
Code:
public function getPegsInRow(row:int):Array
{
var pegRowArray:Array = new Array()
for(var i:int = 0; i < pegArray.length; i++)
[code]....
Unfortunately, the array does not get sorted correctly.
A few hours ago I've asked how to create a custom component (textInput and label component and created a Component Definition) and with your answers I can do that now.
Problem 2: I'd like to use that component in a datagrid column so that the user can type a value in the textInput which will in turn update the underlying dataprovider. I know I should use a cellrenderer like I've done with a checkbox column
I extended the DataGridColumn because I wanted to include a custom itemToLabel function (to be able to show nested data in the DataGrid. See this question.
Anyways, it also needs a custom sorting function. So I have written the sorting function like so:
private function mySortCompareFunction(obj1:Object, obj2:Object):int{
var currentData1:Object = obj1;
var currentData2:Object = obj2;
[Code].....
Whenever I try to sort the column, I get the error "Error: Find criteria must contain at least one sort field value."
When I debug and step through each step, I see that the first few times, the function is being called correctly, but towards the end, this error occurs.
The sorting capabilities that are available in Flex assume that you have access to all the data, but I'm using a paginated datagrid (with custom code), the datagrid is binded to an ArrayCollection instance, on the next page call I change the data of the dataprovider and everything works ok, but for sorting I need to override the click or event better override the sort method of the arraycollection
All this is to be able to do a server-side sorting.

how to reorder an array based on the information contained in another array. What my script is currently doing is detecting all the attached monitors I have and then ordering them based on their left bounds. However I then want to reorder the screens location in the array based on whether the user has selected that display or not. If the user has selected it, by clicking a button, the button movie clip will be on frame two, if they haven't been chosen it will be on frame one. So what I am doing is then creating two separate arrays, chosen screens and not chosen screens, and then combining them into one.
Code:
if(displayButton.currentFrame==displayButton.totalFrames)
{
//sort the chosen ones into an array
[Code]....
My problem now is being able to reorder a separate array which contains all the screens, called screenArray, based off of that. screenArray currently returns [Object Screen], [Object Screen], [Object Screen], etc... and is in the order of 1,2,3,4,5,6. How do I take then and get it to be equal to the order of my displayButtonsChosen Array of 1,3,5,2,4,6?
I'm using a custom component CheckBoxList DataGrid (http://blogs.adobe.com/aharui/2008/02/checkbox_selection_in_datagrid.html) and as dataProvider I have an ArrayCollection with items such this one:

I would like the CheckBox list updated when the selected attribute is set to false or true in the data model.
I have a custom component as an item renderer.In this renderer there is an item called dlFirstChoice.Now when I add more items to this list and force the list to rebuild itself something odd happens.Part of the creation of the renderer I set a default selection for the DropDownlist as follows: dlFirstChoice.selectedIndex=0The problem is once I have more than one item to render from my dataset this property stops working. So if my dataset has only 1 item to render the drop downlist sets itseld up properly, the momment I need to render more than 1 copy of my item renderer, all of a sudden nothing gets set fo

View 7 RepliesWe have a requirement to show a list of appointment slots. So every hour of a schedule has a set of 10 min slots. The requirement is that if we click on a arrow button at the 8:00, 9:00 hour slot, the layout of the hour slots should change from a vertical list to a horizontal list.For this we modeled the system as follows:ScheduleComponent ->(contains) -> List (Hours of schedule)The HourViewComponent is an Item Renderer, that displays the 10 mins slots based on the available appointments by using a Slots List (list of slots in the 8:00 hour). For the Slots List we have a Slot View Component as an Item Renderer.Now the issue is that when we click on the 8:00 slot we are able to change the HourViewSlot from a VerticalState to a Horizontal state. But The container height is not collapsing in the minimized state. It occupies the same size as the vertical layout! We tried using variableRowHeight attribute.
