Actionscript :: Flex : Ensure That Events All Travel Down One Object Tree, Regardless Of Target?
Mar 5, 2011
I have numerous objects, many of them are stored within other objects (and overlap in physical space). As I zoom into an object, it begins to fade away. At the moment it begins to fade, I load in the child object (or create a child object if one doesn't exist). I want to turn off the parent object's ability to respond to most events. The exception is the scroll wheel, which needs to be sent to both objects simultaneously so that the parent can continue to fade out as I zoom farther in. Try as I might, I can't find a way to tell Flex "hey, for right now dispatch these types of events ONLY to this object." I either end up with event dispatch stack overflows from trying to manually redirect the events, or I get events that don't activate at the correct time or on the correct object. What can I do?
I have a tree with nodes , and a delete button , first user select the node and click this delete button , I want this node to be removed from the tree , Its not XML , every node in tree is of type Object
{label:'folder',children:[{label:'file1'}]}
I tried delete myTree.selectedItem (but compiler wont let me do it) also tried myTree.selectedItem = null (just unselects the item)and also how can I access reference to parent object of myTree.selectedItem ?
I have an AdvancedDataGrid tree with a ArrayCollection as its dataprovider. Now, for instance, i drag a leaf from one node to another node. To catch the event I'm adding a Listener to dragComplete.
[Code]...
My Problem: I want to know the new node where the leaf was dropped. Actually i would have expected that in the event there is a property like dropParent. This is not the case.
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?
and theres probably a simple solution but i dont know. I have an object travel at a constant speed across the stage area from left to right, How do i stop it at the Right side of the stage??
I have a simple object defined by an object literal, and have a couple functions assigned to this object. Inside the functions, I try to access global variables, and it only gets undefined. The Flex debugger tells me the variables are just right up the scope tree.Yes, I know I can access Thing by using 'this', that doesn't solve my scope issue though.Project Flex Compiler Settings: Flex SDK 3.4, Require Flash Player 10.x.Example:
Since there is no way that you can make the flash object transparent, there needs to be some other means by which you can match the background. I thought of maybe creating a ActionScript/Javascript bridge, but I wonder if this is the route to take.
By default, the iconFunction of List and Tree return only Class as the icon, which is for embeded images or iconUtility kindly provided by this site http:[url]...... It works very well with pre-created images.But what I really want is to accept a completely runtime generate sprite object, similar to what is done by Legend, with the color changes according to what the current status. I assume I could do something to make the ListBase to accept icon argument other than Class.
I am working on Air application,i had a problem on Tree control.Iam adding nodes for the tree dynamically, while adding nodes to the tree i am setting Tree.selectedItem as present added node. after that i need to fire Tree.itemClick event handler method also.how can i call event handler method as a common method. in Flex3
whats the best least buggiest way to ensure that on mouse over, the moused over object is the last child of the parent, and will appear in front of everything else?
I am using an component, and currently have a dataProvider working that is anArrayCollection (have a separate question about how to make this an XML file... but I digress).Variable declaration looks like this:
[Bindable] private var _dpImageList : ArrayCollection = new ArrayCollection([ {"location" : "path/to/image1.jpg"},
I am having trouble wiring up an event listener to a fl.transitions.Transition.
Is it possible to somehow view all the events an object fires? That way I could check I am using the correct event (and possible view better ones to use).
I'm trying to recreate a UI for an application that my company makes in order to create an in-depth training companion to the application. One of the features is a weird tree view that works quite different from any tree view component I've ever seen, so I decided to create my own version of it as the Flash AS2 Tree Component doesn't have the functionality, and I haven't found any Tree Component for sale or download that works like that either. At first glance it seems like a standard Tree, except that it behaves differently if you click on the icon for each node than if you click on the label.
Some labels are links, some nodes can have 2 different labels, each with their own link, and most nodes have a second label underneath the label next to the icon (these don't have events assigned to them; they're just a quick way to view information). So anyway, I set up an XML file with all the information that I need (the easy part), but populating the whole thing, making sure each subnode can properly exist within each parentnode while allowing me to open and close them has been a real challenge.
Basically, I decided to use a whole bunch of loops to go through the nodes in the XML, but my lack of experience in using them is kicking my rear end. Basically, I need some code that can evaluate all the nodes in the XML and sort them within the proper hierarchies and then create all the clips in the stage to add the mouse events for opening, closing, and handling the links (which do not direct to the same event as when the icon next to that link is clicked).
i have made a list control. i want to display the name of the objects in it in a text control box
the code i am using here is
public function add(event:MouseEvent):void { var str:String; str = mylistcontrol.dataProvider.getItemAt(0).toString();
[Code]....
The problem with this code is i am using index value of 0. however i want to display the name of object on which i have clicked or which is highlighted.
Few users of my Flex 4.6 web application are complaining, that the mx.controls.PopUpButton at the right bottom corner of it sometimes opens a List underneath it and is thus unusable (I can't reproduce that myself - probably an unlucky combination of their Flash player and/or font size setting?)
How could I ensure, that the popUp component (in my case it is a spark.components.List) always opens above the PopUpButton?
I suspect, that I should create a skin based on mx.skins.halo.PopUpButtonSkin and assign it to my PopUpButton? And I probably should use the PopUpPosition.ABOVE constant together with the PopUpAnchor?
I have prepared a screenshot and a simple Text.mxml:
I still can't reproduce the bug myself, my users aren't very helpful (mostly older folks, playing my card game). I've searched in Adobe JIRA, but couldn't find such a bug.
I wonder, if there is a way to short-circuit that method to enforce opening the popUp above the PopUpButton.
Or if I should put the _list into some container...
When code changes for allItems the item disapears from screen as expected but still sits in memory! I know this by a function inside a compoenent that has "trace" so the trace output still displays even after the component disappears from screen. How do I ensure that the element is deleted when it's reference is deleted? Will using List-based component to display items instead of "Repeator" solve the problem (it requires significant refactoring of my code so I'm asking before trying it out)

If I want to align things vertically in a container, I'll use verticalAlign="middle", but this doesn't exactly solve the problem of truly aligning text vertically. Text is always too high vertically, so in the past, I've just adjusted paddingTop and paddingBottom to compensate, but that doesn't work as the font for _sans differs from operating system to operating system.
Given the following layout code, you'll see the problem:
What happens is pretty clear. The horizontal line gets aligned to the exact middle of the box, but the text is offset by some arbitrary amount. I assume that this is because of the text baseline alignment or something. Is there a way to fix this regardless of the font size and face? I'd like to have the line essentially go right through the middle of the text, ignoring the extra space possibly needed for below the logical line of text (ie: ignore the bottom part of "g's" and "j's" when laying things out).
Is it possible to define the target of a MouseOver event being sent to a method if it is being triggered by code and not an actual mouse event? By typecasting a string as a mouse event the receiving function is sent an acceptable value required by it to run. It will then go about executing it's tasks but if it has references to the target property an error is thrown because only the event type was sent to the function and none of it's properties.
ActionScript Code: private function myFunction(event:MouseEvent):void { trace(event.target.name); } myFunction(new MouseEvent("mouseOver"));
Resulting error: Error #1009: Cannot access a property or method of a null object reference. Is there a way to send the target information along with the event when triggering a method in this way?
Is it possible to get the target/origin of errors and error events when using UncaughtErrorEvent.UNCAUGHT_ERROR ?
I am logging runtime errors of users using a complex flash app and would like to know where things are failing. The target of the UncaughtErrorEvent is tracing as LoaderInfo (which is, I assume, because it is also kicking out the UncaughtErrorEvent) and the target of the ErrorEvent is null.
i am trying to do a simple blackboard on mouse down, start drawing on mouse move, if drawing, draw line on mouse up, stop drawing i set the listeners on a simple clip with a rectangle. if i dont fill the rectangle, the mouse events wont fall into the rectangle, but if i fill the rectangle, it will paint behind the rectangle, so anyway i wont see any succesfull results. what i did was create another sprite and paint within it; something like
i need to make for a community a flash tree structure,everytime a user posts a message i must generate more tree brances and Tree Leaves..i include a image..
Can I move a Flash object within the DOM without it reloading? I am developing a simple video chat application. Whenever I move a flash object within the dom tree, it resets itself. I have multiple streams which are aligned horizontally. Every stream is a different flash object. When someone enlarges a single Flash object, I need to move it to the top.
Whenever I move it to the top, that particular video resets itself, and you wait for a couple of second to get the stream back. I am currently simply prepending the same list item to the same parent. This is a very important feature and any kind of solution which doesn't require flash to reset itself is acceptable. (Except creating a parent flash container which has all the streams within it.)
I am trying to traverse object tree in AFL (adobe flash lite) engine, to check if there are memory leaks in an event driven application (AS3). The idea is to get object tree dump before and after an event processing and check the object tree dump difference for memory leaks.I believe MMgc is the GC for AFL, I am unable to get a dump of object tree, can anyone help me to point out where in code I can get the alive object info in tamarin.
