Flex :: Tree Space Default Event Listener?
Oct 7, 2010I have noticed that when I select tree node if space is clicked the selected node gets opened... how could I remove this event?

printableInvoice.addEventListener(batchGenerated, printableInvoice_batchGeneratedHandler);Results in this error: 1120: Access of undefined property batchGenerated. I have tried it as FlexEvent.batchGenerated and FlashEvent.batchGenerated.
The MetaData and function that dispatches the even in the component printableInvoice is all right. It I instantiate printableInvoice as an mxml component instead of via action-script it well let put a tag into the mxml line: batchGenerated="someFunction()
I have a Tree component that's used as a navigation menu between different 'pages'. When the user clicks a certain option in the menu, I switch the 'page' by switching between State components in my application. The thing is that when the user indeed clicks an option in the menu, I want to perform a validation of some of the information in a certain component. If the validation fails, I show an alert, and I'd like to prevent the navigation to the other page. One part of this is simply not changing the currentState of the document, but the tree component still goes on with the change event, and the result is page A still being shown on the screen, whereas the selected option in the tree is page B (to which the user wanted to navigate, but failed since some of the information wasn't valid).
I tried to figure out how I can cancel the change event on the tree component itself. The thoughts I had didn't quite fit nicely:
I searched for a slightly different event (such as 'changing' or 'startChange') on which I can call the stopPropagation() method (since the regular 'change' event is not cancelable), but none exists for the Tree component.
I also thought about always saving the current option that's selected in the Tree component by myself, and when the validation fails, I will set the Tree's selectedItem to that saved option. That's also ugly because such an action will raise another change event on the Tree, thus another change to the States components, and another population of the page in which I'm already at. That's something I really don't want to do.
I also though about using a different component, such as Menu (and I also found an implementation of a vertical Menu), but that doesn't even seem to help. The same problem will exist there.
There must be a best-practice for preventing a change process to commit!
i'm creating a reusable flex tree component. And i would like to stick in the itemclick funtion. So that when a user clicks anywhere on one of the tree's Branches. the branch expands.My problem is that i don't know how i can get the listener function to fire.What i would like to do is create the tree completely in as3. (no mxml). Normaly i set the itemClick on tree in the mxml. but i want to do this in as3. My component has alot more functions in it but i have deleted them so that it becomes easier to read. I Thought if i override the createChilderen function and add the eventlistener in there, that i would work. But no luck.
this is my code;
package
{
import mx.controls.Tree;
import mx.controls.listClasses.IListItemRenderer;

i have a tree component that dispatches an itemOpen event. When the black triangle next to the yellow folder is clicked, that folder opens to expose its children.
Is there anyway to know the index of the open folder? there is a rowIndex property in the target property of the openItem event that stores the index but it is not accessible.
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?

View 4 RepliesI got a reference to an arrayCollection and add event listener like this:
collection.addEventListener(CollectionEvent.COLLECTION_CHANGE, onCollectionChange);
That's fine. Now some other component does have the same reference and is adding items to and removing items from that collection.
Each time the handler is called:
private function onProjectPersonsChange(event:Event):void {
if (event.kind == CollectionEventKind.ADD) {
//do something
} else if (event.kind == CollectionEventKind.REMOVE) {

Why the removed item is not in 'items'?
In our app, I am periodically noticing that a particular event handler is not firing. 99% of the time, it works fine, but, every so often, it just dies. How can I find out whats happening? Is the DispatchEvent() not happening/working somehow? Is my listener still listening? Did something else catch the event, and not pass it along so that the 'right' listener can get to it ?
Here's a little bit of the code...
Thats a somewhat pruned down version of what the real code is, but I don't think I trimmed out anything important. The key, as I see it is that we fire up the params dialog, then start to listen for the closed event. Then, we show the param dialogs close function. What happens when it fails is that the trace message "caught close event.." is never generated, and, consequently, the closeHandler is not getting called at all.
let's say that i have this button which is called "Click_Here" and i added an event listener to it in some class file in order for it to run the event handler in a different one .. so it will be like this
classfile1.as
Click_Here.addEventListner(MouseEvent.CLICK , buttonClicked ) ;
classfile2.as
public function buttonClicked (e:MouseEvent){ trace ("hello");}
We have a flex application that connects to a proxy server which handles authentication. If the authentication has timeout out the proxy server returns a json formatted error string. What I would like to do is inspect every URLRequest response and check if there's an error message and display it in the flex client then redirect back to login screen.
So I'm wondering if its possible to create an event listener to all URLRequests in a global fashion. Without having to search through the project and add some method to each URLRequest.

I know I can create a custom event and associate data with it and retrieve it in respective Event Listener. But What I am interested to know is, is there a short method (without having to extend Alert Event Class) to associate parameters to its alert Listener.
View 2 RepliesI want to add an event listener to each component inside a repeater, but don't know how. Here's some code I have tried:
<mx:Repeater id="rp" dataProvider="{dataProvider}" width="100%">
<mx:Button id="attach" creationComplete="addListeners(attach[rp.currentIndex])"/>
</mx:Repeater>
This doesn't work. creationComplete is not called until the repeater has finished instead of (as I expected) when the creation of the button is complete. I'm not sure how to accomplish this.
BTW - I also tried placing the creationComplete on the parent component to the repeater, but it would only be called the first time the component was rendered (the data inside the repeater sometimes changes) so that didn't work.
it's possible to change the default key (space bar key) to execute the action of the focused element in the stage?If you ever worked with the Focus Manager you've possibly seen that when you press the space bar the focused item is "executed".Can you disable that "executor" or can you change the space key with the enter key?
View 2 RepliesI am writing a web application that will serve as a configuration for a random data generator that I have written in Java.The values that I set in this application will write to xml. The xml data is updated by a file called simulationParams.as and that file is added to each child in the "viewStack" so that when I change any of those values the simulationConfig file will be automatically updated.The problem is that when I press the randomizeBtn the proper events are fired and the listeners grab those events.My problem exists when I uncheck the randomize button.For some reason an event is triggered or the listener isnt listening so that when I uncheck randomizeBtn the values go back to their last position or value on the slider. Ex. if my initial value is 0 then press randomize the slider will go to 100. The config file updates and all is well.When I uncheck the randomizeBtn, the sliders value goes back 0 but the config file isnt update.The same thing happens when I press the useDefaultBtn for both selected/unselected, nothing gets updated.[code]

View 4 RepliesI have a tab navigator defined in MXML, with two tabs.In each tab, I have some buttons. I have used ActionScript to add event listeners to all the buttons, and they work for the buttons that are visible (and in the currently "active" tab) when I load my Flex 4.5 AIR application.However, I get an AIR error for the event listeners attached to the buttons in the second tab.Here's the crucial part of the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.
View 1 RepliesI'm trying to add an event listener to my air application that would prevent the "ActionScript error" window from appearing, so I can handle the error within my application.I was able to find a little information about this from adobe. I'm just not sure what I should be listening for.
View 3 RepliesI have a flex tree that worked perfectly fine when we set the defaultLeafIcon={null} and the folderClosedIcon and folderOpenIcon to {null}. We decided to put the icons back in and took out the nulls. Now they show up fine, but if you click on the icon instead of the label or the rest of the row, it seems to change the selected item, shows the highlight around the new item, but doesn't dispatch the ItemClick event. This makes it really hard to know that the tree's selected item has changed!
The weird part is that once you have clicked on the icon once and it looked like the selectedItem changed (or at least it applied that style), if you click the same icon again, it will actually fire the itemClick event. if you click any other icon, it does the same thing again, switching the selectedItem and styling that row, but not firing the itemClick event.
I have multiple items in my app that I would like the user to click on.Some items are completely different classes.The classes dispatch events and then when the events are captured, some modifications are done to the transform properties of a loosely coupled display object.I want two separate classes to dispatch the same type of event, since I already have an image class that draws images based on a given url... I want the classes to dispatch the events, but then I think I want the difference to be detected when the event comes along... i.e., I would like to recognize the 'origin' or 'sub-type' of the event. Some sort of if/then logic would suffice.
View 1 RepliesI am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
View 3 Repliesif I have an event listerner (mouse, keyboard, enterframe,....event) that is being triggered, and when it finishes its event, something that is able to detect the finished event listener and fire out another sets of event.
It works more like MOTION_FINISH in TweenEvent, but it is only available for TweenEvent only, what if I want to detect a mousclick, keyboard, enterframe or even touch event?
