Actionscript 3 :: AddChildAt() To Add Item At Specific Index Position?
May 16, 2011
I have a textBox and I am using it as a mail address input field where the user can type in several addresses, a bit same as in hotmail. Each address is rendered into a clickable button. Thus upon double-clicking on a specific address I want the item to be editable. After having edited the address when the user taps enter, the item is added to the list of mail adds.I am adding it using the code below:
flowBox.addChildAt( myItem, myindex);
However addChildAt seems to add the item as the last item in the list. But I want it to add the item the position where it was originally. Say the item was at position 2 in the mail list, after editing adn tapping enter, it should add at position 2 itself and not at the end of the list.

If I have several items that move across the screen but the user can click any of them at any time, how do I record the current position of any of the items item in order to use that data to change the position of the item after the user clicks?
This is what I am doing: I have 11 images that slide accross the screen. The user can click any of them at any time. When he clicks one I am scaling the image so it looks like it is comming forward (z axis) and then the rest of the images are scaled down so it looks like they are going back on z axis. So what I am trying to do is get the current position of the image when the user clicks the image so that I can use that to correctly estimate the scaling and moving of the image to make it look like it scales from the center and not from the top left corner. So if have a variable that gets the current position of the image being clicked I'm thinking I can change its position using something like: x = currentposition + -45;
I have a tricky problem in that I have an array that has been populated with strings ("item1", "item2", etc). However, at a certain point I need to pull one randomly out of the group, via a random number function. The issue is I cannot reference the items in the array by a number, I get an error. So when I try to get myArray(5) it doesn't work.
How can I work around this so I can grab a random item in my string array?
I've got a subclass of AdvancedDataGrid showing a tree-like data structure. How can I, given the index returned by calculateDropIndex, get the item at that index? After reading through reams of code, it seems like the least terrible way is:
var oldSelectedIndex:int = this.selectedIndex; var mouseOverIndex:int = this.calculateDropIndex(event); this.selectedItem = mouseOverIndex; var item:* = this.selectedItem; this.selectedIndex = oldSelectedIndex;
The other option seems to be tinkering around with the iterator property... But, judging by the way I've seen it used, that will get pretty harry pretty quickly too. So, how can I get the item at a particular index in an advanced datagrid without going insane?
I'm doing a drag and drop operation on a tree using some help from Adobe's quick Starts:[URL]
The code suggested is roughly this:
var dropTarget:Tree = Tree(evt.currentTarget); var i:int = dropTarget.calculateDropIndex(evt); myTree.selectedIndex = i;
[Code].....
EDIT: I forgot to post that my current workaround is setting the selectedIndex = -1 after I get my node:XML. I'm afraid that if something bogs on the processor the user may see it select then deselect.
I've been trying yo convert Lee 3D carousel tut to AS3 and it pretty much there apart from one thing. I took Lee's as2 carousel 2 and applied what I know to convert it to AS3. I couldn't work out how to re-index each item properly. When the last item in the XML should appear under an item to it's left or right it does not due to numbers being rounded from the scaleX value being too close and causing the same number to be generated from more than one item therefore last item to be processed ending up on top. I've tried a few alternatives, but nothing has worked so far. Hopefully that makes to sense to someone.
If you download the files from Lee's tutorial http:[url].... open the fla, change the publish settings to Flash Player 9+ and AS3, remove all existing AS code, check the library item linkage as I've capitalized everything and add the following to the root timeline.The code causing the problem is this in the function mover:
i see that theres the array.push and array.unshift, but thats just the beginning and the end of the array. how would i go about inserting an item(s) into an array at the desired index?
I have a label inside a repeater (rptInfos), and I have an arraycollection (Texts) that has the translations. The "Texts" content is changing when I change the language, and normally I use {Texts.getItemAt(219}} for example when I need a translated text. But in the repeater I have a translateable column, so I want to use it like this:
<s:Label text="{Texts.getItemAt(rptInfos.currentItem.DictID as int)}" />
but it says "Syntax error: expected a definition keyword (such as function) after attribute , not target".I wanted to translate it in the labels creationComplete event, but than I can forget about binding, so only when reloaded can I have the content to update.
I am trying to get the index of an item in a List object on a mouse roll over event (please keep in mind this is not the selectedIndex I need). Heres the code I am currently using: list.addEventListener(ListEvent.ITEM_ROLL_OVER, onItemRollOver); function onItemRollOver(e:Event):void { var itemInfo:Number = 0;
/*This is where I need the Index Number of Item being Rolled over instead of Selected Item*/ itemInfo = list.selectedIndex; txt_Display.text = 'Item Index #: ' + itemInfo; play(); }
I'm trying to get an absolutely positioned DIV to display in front of a Flash object; I can get this to work in every browser except Chrome.There are a couple of similar questions on here, but nothing pertaining to a problem with Chrome specifically. I've tried several of the suggested solutions, such as setting the 'wmode' param to 'transparent', and setting z-indexes for both the flash object and the div, but nothing seems to work.URL...There is some green text: "Click here to begin", which should appear in front of the Street View panorama. In Chrome, you can see that the DIV appears in the correct position, but is then obliterated by the Flash object.
I change an item in Spark List. The item then moves to a different index in the list since I keep the List's dataProvider sorted. However, the selectedIndex stays where the item used to be. I want the List's selectedIndex to still be on the item that changed.
i have a few filters on a sprite. on mouse over i would like to access one of the filters in the filters array, but i'm having a bit of trouble trying to accomplish this.
I need to insert string in another string in specific index. var str1:String = "A"; var str2:String = "LoremIpsum"; I need str2 to be "LoremAIpsum", insert str1 in index 5 in str2.
I would like to edit a cell by the row and column indexes so essentially do the following:
advDataGrid[2][3] = "Dogs"
so that I am setting the data grid row 2 and column 3 to Dogs. I cannot for the life of me figure out how to do this!
Side note: I need this because I am trying to allow the user to copy a section of an excel file to a section of an AdvancedDataGrid like Google Docs does. I am using this idea to do it: [URL]
how to get the X and Y coordinates of a character in a string based on index? I find it odd that I can get the exact letter and index by clicking a character in a text field, but I haven't found anything in code that can get those coordinates without a user click. Seems like they would have to know the x,y of the individual indexs to be able to tell you what letter you're clicking based on your own mouse coordinates.
I am making a dragable map and there are few thing on top of the map(UI). When the map is double clicked it enables drag. But it's changing the index position, basically, it going over the UI. what's the easiest way to control the index position of the map? The click and drag event is controlled in mapZoom class.
this.addEventListener(MouseEvent.MOUSE_DOWN, enableDrag); public function enableDrag(e:MouseEvent):void { this.startDrag(); }
I have a combobox that displays a list of items from an array (we'll call this Array1). Of course, an item can be selected, and the user is displayed a small output describing the item that was selected.
I created another array that contains the URL for items in the above array, Array1. How can I get the index value of a selected item from Array1? Here is the code I used:
[Code]...
For example, if I selecte FontsForFlash, Flash outputs Fonts for Flash in the Output Window. How can I display the array position of Fonts for Flash instead of the name Fonts for Flash?
I have battling for weeks over how to put a flash file on my frontpage. I want to know where to put the flass file.below is the script for the index.php of my page
I want the selectedIndex to remain the same. So, if I delete item 2, the next in the list should be selected. The problem is that if I delete item 2, item 3 will be selected and I have no idea why.
I'm writing a game with Flash CS5/AS 3.0 that tries to simulate depth of field by drawing all the relevant Movie Clips based on their Y position in ascending order, i.e. things lower on the stage overlap things higher on the stage. A MovieClip with a Y position of 10 would therefore need to have a lower index compared to a MovieClip with a Y position of 20, so the second one gets drawn on top of the first.
I wrote a quick and dirty function just to test this. During the trace, I've noticed that the truck's index hits 0 when I go near the top of the stage, but if I go too far up it will completely disappear from the stage. Trace then starts generating this error:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. at flash.display::DisplayObjectContainer/getChildIndex() at EICT::Game/ReorganizeDisplayIndexes()
I'm trying to build a function that finds max-value in array of numbers and returns index position of the value (in AS.3.0)I already have this.....but it is not helping me finding the index number.[code]
