IDE :: ScrollBar - Binding Controls To Layers
Mar 16, 2010
I am trying to build a flash project, where I've added a number of Datagrids to a layer and I am using masking to show only a part of the layer. And I have added custom scroll bars to scroll through the layer, so far so good. Now when I am using the scroll bar the layer seems to scroll perfectly fine but the controls on the layer are just static. Is there a way to bind these controls to the layer and scroll the entire layer with the controls. I am new to flash.

I'm working (for my sins) on a Flex 3.3 project, which unfortunately cannot be upgraded to a newer SDK version at this stage, and have hit an issue with the custom hierarchical tree class (subclassing mx.controls.Tree) we're using. Excuse the spelling; the previous developer had a fear of dictionaries...
public class HierachyTree extends Tree
public function HierachyTree()
{[code].....
I'm using a solution somewhere between these two methods (basically, implementing ITreeDataDescriptor) in order to add live text filtering to the component, and it's working so far:
public class HierachyTreeFilteredDataDescriptor implements ITreeDataDescriptor
{
private var filter:Function[code]..........
The issue is that (with tree:HierachyTree) neither tree.maxVerticalScrollPosition nor the protected property tree.verticalScrollBar .maxScrollPosition updates when the search string is changed.I've tried calling invalidateList() and invalidateDisplayList() on tree — and calling invalidateDisplayList() and invalidateSize() on tree.verticalScrollBar — to no avail.

Is it possible to specify MXML-esque "binding strings" in ActionScript?For example, I want to be able to do something like:

Is it possible to add layers, re-order layers, move movieclips from layer to layer or specify which layer a duplicate movieclip appears on at runtime with AS3?I am aware of the depth properties and the functions associated with that but it would be easier to have a concept of a layer because I am dealing with masks.I have a nasty feeling I'm gonna be told that layers don't really exist within an swf and that depths and setmask are all there is to work with.

how I would convert this vertical scrollbar into a horizontal scrollbar
heres the code:
onClipEvent (load) {
diff_y = bound_box._height-scroller._height;
bounds = bound_box.getBounds(this);
top = bounds.yMin+(scroller._height/2);
bottom = bounds.yMax-(scroller._height/2);

My application uses fx tag in which it loads some xml. I want to create the xml name by binding, but I get an error that Data binding expressions not supported with attributes processed at compile time.
<fx:XML id="{xml_props}" />

I'm currently looking at ways to externalise all text in my flash applications into external xml files (for translation purposes). Basically, all copy in these applications has to be in two languages (English and Welsh).
At the moment, I'm just looking at a structure whereby the name of each TextField instance is the same as a field in the XML, which then has two fields (<english> & <welsh>) inside with the relevant text. The XML will be loaded in and then looped through applying the text to the textfield of the same name in the current language. There will obviously need to be some error-handling with regards making sure the names match up but this can only be done at run-time.
This seems a bit, I dunno.. lose? Is there are way of creating a better structure or system that'll be a bit less reliant on accurately naming various things so they match?

I actually got it to show up in the dynamic text box, but its also displaying my xml and css tags(The XML file structure). I know the xml and css files both work after testing them in my browser. My XML file only has one node. Below is my AS3 code:
Code:
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onLoadXML);
loader.load(new URLRequest("content.xml"));
function onLoadXML(e:Event):void {
var xml:XML = new XML(e.target.data);
//trace(xml)
textBox.text = e.target.data
}
I just need it to read the content and follow the css code that's been attached to it.

I'm trying to make a td game for fun and I need to make function to build towers and if I want to build the second tower it changes the first one... But I thought if i could change the name of the first tower's name when it builds to other var and it should be fine, but the problem is that those 2 towers will shoot together or something, so is there a way to bind functions to movieclips that are created with actionscript (addChild(Name))?

first one shows playheadtime of videodisplay and another is also used for same purpose. the difference is that when we are in add mode(decided from a flag variable) both should show current playheadtime using binding. but when we are in edit mode(again decided from flag) the latter label should remain static, to be more specific, the value retrived from database.how can I do that using actionscript. I tried ChangeWathcer but I found it a bit tricky. Is there any other simpler way or am I missing something. following is my code.
private function init():void
{
if (queFlag == 'a')

I want to load key/values configuration pairs stored in XML file. To bind a collection of data i know i need to use the ArrayList class, but the problem is that i want to be able to bind the loaded values using their corresponding keys and not by their indexes in the ArrayList object. For example i want to be able to do this :
[Code]...
So the question is how to bind the key/value pairs loaded form XML. I don't want to go manually set variables, i want to bind them so when they are loaded the are set automatically. Did anyone had to do something like that ?

I have a datagrid that gets its data from a webservice.When data from the webservice is retrived it calls the following function:
private function onListReg():void
{
arrRegOld = WSAutoreg.list.lastResult as ArrayCollection;
arrReg = WSAutoreg.list.lastResult as ArrayCollection;
[code].....
The intent is when I hit a update button, it compares arrRegOld with arrReg and see if any values have changes. The problem is whenever I change values on the Datagrid it changes on both the dataProvider and on both ArrayCollections.What should I do so that the binding applies only to one ArrayCollection?

I'm having some troubles with binding data. I have an application that contains a viewstack of components. Let's say I have comp1, comp2 and comp3 inside the viewstack. Each component, has its own data class --> comp1Data.as, comp2Data.as and comp3Data.as. All values in each component are binded to the corresponding data in it's data object.
A click in a control in comp1 leads to comp3, the same goes for comp2. Clicking a control in comp2 leads to comp3. When going from comp1 to comp3, comp3Data.as is initialized and and comp3 displays the binded values. When going from comp2 to comp3, comp3Data.as is also initialized but the binded values are not displayed...

I am using flex SDK 3.5. I have model.as and in it i have an ArrayCollection (name it arr_mod) which is Bindable.
From my mxml i link to this arr_mod in three places:
1) in DataGrid i set dataprovider={arr_mode} ...
2) in Button i add new item to the arr_mod this way: mx:Button .. click = "{arr_mod.addItem(new Item)}"
3) in textBox i want to add mx:TextBox text="{mySpecialCounterFunc(arr_mod)}"
note that in the Script of mxml arr_mod is Bindable as well as in the class definition in model.as
The problem is, that when clicking on button, mySpecialCounterFunc is not called! it should be called, since i use {} and this should listen to changes in arr_mod (a change that was made in the button should cause a new item to be added.. and than the listener to respond). While The DataGrid is updated correctly! By the way, if i change arr_mod to simple String or Int it works.. i.e. mySpecialCounterFunc is called Why??

I'd like to add a derived property to flex:[code]However, derived won't update when I change a or b.Is there a better (faster) way to make derived update than giving a and b setter methods which invalidate it?added keyword "get".This makes more sense now, I hope.

I have created a really simple example for what I am trying to achieve, which you can see below.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" horizontalAlign="center" verticalAlign="middle" initialize="init()">
[Code]....
So it is important for me to bind to the children().
Is this possible and if not, does anyone know how I will get round this issue?

I've been kinda stuck in trying to organize data and bind them to a Repeater in one my applications.What I did at first, was to save an array of arrays, so that I could've accessed any value very easily. But then I realized that I needed to bind them to a Repeater, so I had to switch to an ArrayCollection of arrays. But the Binding issues weren't solved, since there are still arrays (not bindable) inside the ArrayCollection.Below an example of what I want to do:
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable] public var arr:ArrayCollection = new ArrayCollection(
[code]....
the traces show that the array size changes, but the repeater doesn't update.

I have several components where I want to enable buttons based on passing a username to a function. I want to dynamically bind the "enabled" property on a button so that if the "somethingChanged" event fires, a button may become enabled or disabled. But, I'm not sure where to fire the "somethingChanged" event. It's possible that I may need to fire the "somethingChanged" event from several places in the application. Is this possible with a bound static function?
EventManager.as
public class EventManager():void {
[Bindable(event="somethingChanged")]
public static function hasAccess(myVal:String):Boolean {
}}
