Actionscript 3 :: Flex Tree With Infinite Parents And Children?
May 17, 2010
I am working on a tree component and I am having a bit of the issue with populating the data-provider for this tree.The data that I get back from my database is a simple array of value objects. Each value object has 2 properties. ObjectID and ParentID. For parents the ParentID is null and for children the ParentID is the ObjectID of the parent.
Essentially the tree should look something like this:
Parent1
Child1
Child1

I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?

ok, my Digital arts class is making a flash project, and im like the only one actually making a game, so im pretty much alone. i got a lot of help from the people on the AS3 forum, but im pretty sure that my question is too easy to put there. so, i have an array, and it basicly puts a spike on the screen at a random Y, and moves it across the screen, but, when i hit a spike, and ti goes to the you lose screen, the loop keeps adding children, and putting them on the screen, is it possible to just say stop adding children, and go to the next frame? i have a break, but when i stop colliding with the spike in the next frame, the spikes start coming again. also, can i totally reset the movie? cause when i just go to frame 1, the array plays itself ontop of itself and it gets twice as hard

I have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down.. i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?

Okay, here is the relevant files for a game I am making and their structure: -Stage -->MainMenu.as --> NewGame.as --> beachArea -->barrel.as.................................................. ......-->player.as.................................................. ......--> pistolBullet.asSo, am trying to detect when a bullet hits a barrel. I was going to use the hitTestObject() functionI got as far as trying to actually access the properties of an instance of barrel from the pistolBullet.as and seem to be a little confused as to my findings.. Can anyone explain to me why the last trace function returns undefined?pistolBullet.as:
Code:
trace("pistolBullet.parent: " + this.parent);
trace("pistolBullet.parent.beachArea: " + MovieClip(this.parent).beachArea);

This may well just be because it can't be done but here goes.Does anyone know of a way that I can make a MoviecClip "visible=false" whilst stopping just one of its children's, children's, children...etc from also going invisible.I am aware that it can be done by setting them all individually but this will take a lot of code (and I like tidy code...and I'm lazy), and I am reluctant to use a loop as it will interrupt the animation that is going on at the time.

I have added an event handler for itemOpening event for the tree component inside the handler basically ido myTree.selectedItem = event.item ; and then add the new data inside myTree.selectedItem.children.push(newData); But It do not show simultaneously instead I have to close , open the branch again to see the new data. I think I need to refresh something after adding new data but dont know what? below is the code but without the declaration , script tag etc

I have a tree with a dataprovider which takes the following form:
<details name="Cars">
<contact_person>aaaa</contact_person>
<list>
[Code].....
That is I want to hide the contact_person and list nodes.Deleting the nodes from the dataprovider cannot be done.So what i did was to create a custom tree data descriptor by extending DefaultDataDescriptor.Then override the getChildren method and applied a filterfunction to the collection returned by super.getChildren.The problem is when i hide the 'list' node I cannot have the child nodes to show up.So is there any way I can hide 'list' but show the children of 'node'?

Seeing as I don't have too much formal education Flash/OOP in general, this is just one of those thing I can't seem to quite deal with gracefully. All I'm trying to do is to be able to load/reset my an instance of my game's main class (not the first class that gets pulled up by Flash, but the one that actually has games logic in it), which of course extends MovieClip. It took me a while before I could even make an instance in it, because it would silently crashed when I would try to do so, and what didn't help was that the output window stopped working, and I had to completely reinstall flash. As far as I remember I simply fixed it by taking out the "stage." from any of the lines of codes that had it.

I'm trying to build a menu system which populates itself by parsing labels from the Flash timeline. As well I have a requirement to keep this all within one FLA file... so no classes or XML files. After 2 days I'm pretty close here, but have a problem with mouse_out's. I'd like to be able to move my cursor up and down the popped-up sub menu, but as soon as my cursor leaves the first sub button it triggers the mouse_out function.
I want the mouse_out to trigger only when the cursor leaves the entire sub-menu, not it's children. I believe this is a traditional problem and there's solutions but after 1.5 days of tuts and threads I haven't been able to manage it. I think I may just have to tweak how I deal with the submenu array.

I'm working on a web app built in Flash AS3. At a high level - the app has a main screen, and several "modal dialog"-type screens that pop-up to manage various user interactions. (This is a similar pattern I use in most of the apps I develop...) Typically - when the user clicks a UI control on the dialog screen (e.g., button, text box, slider bar, etc.) - the main screen needs to react, or manage the consequences. It seems like there are two general ways to handle this: Have the dialog screen dispatch events that the main screen listens for Allow the dialog screen to call functions in the main screen when those controls are clicked (which requires that the dialog screen maintain a reference to the main screen, and that the functions in the main screen are public)
In general - I understand that one of the key benefits of the first method is that the dialog screen isn't so tightly coupled; it's only responsibility is to broadcast the event. This would allow me to more easily use the dialog class in other contexts, or applications. But for many RIAs I develop - a particular screen is SO SPECIFIC to the the application that there's no chance I'd ever reuse it in another application. So, the "easy re-use" benefit is minimal. So - if you eliminate that benefit - which method is actually better? (More performant, less resource-intensive?) For example - if I use events, then Flash needs to manage many listeners for events that may never occur. So - it might be more efficient if the dialog window could call a function in the main screen directly, instead of dispatching an event.

At the moment, I came across this problem where I have to work with many swf files.The problem is I'm using addChild() & loader to navigate between each swf. It doesn't seem to be a problem at first, but after numerous times of clicking back and forth, the flash player starts running slow.So I've came to a conclusion that eventhough new swf are added every time I clicked, but the parent swf still remained at the back which is overlapped by the child.

I want to basically copy an xml object I have created, take the children from a specified node and make a new xml object from them and put this new xml into the tree component. Can you see what is wrong with this?

i did the tutorial but something is wrong cuz when i created my own little sliding thingy and i put my mouse so it slides left or right on the right side it cuts off a bit when going infinite.I think its something to do with the positioning of my menu because its not on x=0 its on x=120.8 and i was trying to work out how to fix it but i'm stuck...and when i move the menu to x=0 it works nicely.

I have a Canvas which has many components inside it and those again, have many components inside them.
getChildren() returns only the top level children. What is the best way to retrieve all the children (children of children of children and so on).
Well, I sorta know how to do this by iterating through the children, but the code is really messy. I'd prefer to use a nice recursive function. Has anyone written this before? Or is there a Util class to do this?

I want to access a webservice:getMonitorData() , on creationcomplete and returns an array, in an infinite loop so that the getIndex0.text is updated each time.Flex is not able to handle an infinite loop and gives a timeout error 1502. If I run the for loop until i<2000 or so it works fine.How can replace the loop so that my webservice is accessed continiously and the result is shown in getIndex0.text.This is how my application looks like:

I'm new to Flex/ActionScript (.NET/Java has been my main playground so far).I'm trying to build a Flex app that has a list that is meant to look and behave like an infinite list (of items - which can be any object). The idea is that the user should be able to scroll up or down and never reach the end of the list in either direction.
An example would be a list of numbers. Scrolling up will show negative numbers; scrolling down will show positive ones. Now, my list is a simple Flex Spark list (using Flex Hero).It is bound to a data provider that is an ArrayList.My initial idea was to listen to the scroll event and add/remove items as needed. However, in the current build of Flex Hero, there is a bug that doesn't raise scroll events for vertical scrollbars sometimes (http:url].....).So, I'm using the workaround suggested in the link above (i.e listening to the propertyChanged event of the list's scroller's viewport. The event though only gives me the current verticalScrollPosition. And it looks like the default spark list supports smooth scrolling and raises the event many times before the list scrolling comes to a standstill (it is a nice visual effect).Now, I need to :
Figure out whether it is scrolling up or down (how do I do that?)
Figure out which items are visible. I can get this from:
list.dataGroup.getItemIndicesInView()
Add/remove items as needed, so that the user can scroll up and down forever, never reaching the end of the list in either direction.
I've tried the following code but it doesn't work. (comments in code).
import mx.collections.ArrayList;
import mx.core.INavigatorContent;
import mx.events.FlexEvent;[code].....

I have a intro to a picture of a tree which has buttons on it. The intro is an embedded flv video (not using the FLV component). The video starts on frame one and runs to frame 2. The tree is on frame 3.When I click a button on the tree, it runs the respective frames then returns to the tree. When the tree appears, the sound of the video is playing in the background.How can I make this stop?
Code:
stop();
MovieClip(lion_mov).stop();
//video Mouse Click[code].....
Frame 3 just includes all the mouse clicks for the tree.

I have a group for which I want to enable horizontal scrolling. Vertically the group should be as wide as possible (100%).
[Code]...
Now if I start the application the MyComp-component is about 200px wide and starts to expand its width to infinity. This is like some transition or animation and I don't know how to stop it. Setting something like maxWidth would solve the issue, but I don't want to set explicit values.

I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.
