Flash :: Getting Mouse Events From UIComponent Child In A Spark View Does Not Work
Nov 3, 2011
I have a custom UIComponent that is basically just this:
public class WhiteboardUIComponent extends UIComponent
{
public function WhiteboardUIComponent() {
super();
[Code]....
This is absolutely the simplest that I could make the example. The s:View is gobbling up my mouse events - if I add a handler in the MXML to the View, I get mouse events just fine. When adding a handler programmatically in my subclass' constructor, I get nothing. I thought maybe the layout was wrong, so I explicitly set the dimensions of my UIComponent and stuck it in a border just to be sure it was where it was supposed to be - same deal.

I have an AS 3 class that extends UIComponent. In that class I dynamically add several sprites, that are also AS 3 classes that
extend from Sprite.So, in my UIComponent extended class, I added these listeners:
this.addEventListener(MouseEvent.MOUSE_DOWN,mouseDownHandler);
this.addEventListener(MouseEvent.MOUSE_MOVE,onMouseMoveHandler);
this.addEventListener(MouseEvent.MOUSE_UP,mouseUpHandler);
I added trace messages inside each of these event handler functions. The problem is that, whenever I try to dispatch these events starting from one of the children sprites from the UIComponent (let's say I click one of the sprites and the mouseDown event starts) the sequence works perfect. However when I try to do the same in the "blank" area of the UIComponent (which is just a
graphics.beginFill(0xffffff);
graphics.drawRect(0,0,this.width,this.height);
.graphics.endFill();) nothing happens. The events are never
"listen" by the UIComponent.
Actually if I run the app and click on the white area, the trace messages are ok, it triggers the mouseDown event, but only one time. I a click again, nothing happens.I tried adding another sprite, to have this one holding all the other sprites, and tried to add the listeners to it...same effect. I can't get that UIComponent to listen and react, only it's children sprites...
What I'm trying to implement at the end is a multiple drag selection of the children items of the UIComponent, but I have to be able to start the drag selection from any point in the screen.

I have a base ShapeContainer(UIComponent). I add a uicomponent which has mouse down listener to ShapeContainer. the listener works great. When I add a simple sprite(draw square) on the ShapeContainer, The listener does not work any more. In the code, if I comment below line, The event listener works fine.

I'm drawing an arrow as a <s:Path> and I need to get notified when the mouse is over it. How can I do that?
The arrow is an element of a Group container.
I tried registering for MOUSE_OVER events for both the container and the arrow and none seem to fire...

I have some code that gets fired on these mouse events:
button.addEventListener(MouseEvent.MOUSE_UP, function(e:MouseEvent) { ...
button.addEventListener(MouseEvent.MOUSE_OVER, function(e:MouseEvent) { ...
button.addEventListener(MouseEvent.MOUSE_OUT, function(e:MouseEvent) { ...
They all work in all browsers, except for Chrome, where MOUSE_OVER and MOUSE_OUT trigger the events, but MOUSE_UP does not trigger the event. I also tried CLICK, same story.I would suspect that there is some sort of interfering layer or offset in the Chrome rendering, but then wouldn't the other mouse events not register as well?

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 am trying to capture mouse events in flash while the mouse is being held down. The intention is to keep reciving events as long as the mouse is pressed, even if the cursor leaves the flash element. That's the behavior I get on all browsers other than IE, which only fires events while the cursor is inside the stage.
I'm pretty sure I've seen such "well behaved" flash applets work in IE before.

I am working on a drag and drop feature for the sparkScroller. This is sort of how my layout looks:
<mx:Canvas>
<s:Scroller id="items" .. />
<mx:Box id="dummyRow" visible="false" />
<s:View id="touchView" visible="false" />
</mx:Canvas>
So when you hold your finger over a row in the items Scroller for more than a 30 seconds, the touchView becomes visible so does the dummyRow. The dummyRow gets populated to look like the row which you held your finger over.
So the touchView has the event handlers for moving your fingers and places the dummyRow where your finger is. The problem I am having is even though the touchView is reacting to my move events, the scroller still keeps reacting to my move events as well even though it's a sub layer. Because I started on the scroller it still keeps track!
How can I remove focus / tracking from the scroller?

having an issue with some mouse events I have. If you go here you can see what I mean.When you mouse over one of the thumbnail images, a title pops up. If you click one of the thumbnails, the group shifts to the right. (This is making room for what I'm working on right now, it's not just random ) If you then navigate to "About" or "Contact" then back to "Works" neither the mouseovers nor the clicking on the thumbnails works.That middle section is one object called "images" with three frames, each labeled and then navigated to inside the buttons with gotoAndStop(frame#).Here is my code for the buttons and mouseovers:
Code:

I have several sprites nested in containers. Let's say, that there are six containers (each represented by a Sprite) nested. I use the mouseChildren = false property on the container at depth 3, so the containers that lie deeper cannot receive mouse events. But still, I want that the container at depth 6 can receive mouse events

I have a _parent movieclip that receives mouse events and I want the clips inside the _parent clip (child clips) to receive mouse events also, but because of the _parent's mouse event handlers, the child clips are "interfered" with, or not received....how do I make it so both the _parent and the child clips can receive mouse events?

I have an external .swf that I'm loading into a main one. The external one has actionscripting which reacts to the mouse. When exported on it's own, the scripting works fine but when loaded into the main one, nothing works. There are no references to the _root in the external swf either.

I am using a List component inside an itemRenderer. The main user interaction involves dragging an item from the List in one renderer and dropping it in another. My problem: When the data object is updated I want the Lists' height to be modified according to the number of objects in the dataprovider(dp), which is passed to the List from the data object. Now I have tried to invalidate the display of the List, refresh its dp and have tried putting this line assets.length > 0 ? assetList.percentHeight = 100 : assetList.height = 10; in other event handlers, such as dragdrop handlers, collection event handlers for the dp etc. I have also tried refreshing the dp for the List component that is using this renderer. The view does eventually get updated but only if I resize the list, or use the scroller or when I begin dragging a new List item but never after the drop.

I'm building a mobile AIR app using Flash Builder 4.5. The initial view in my views package is TestHomeView.mxml. I want to refer to it in one of my .as classes elsewhere in the app, and I'm not sure how to do that.
Theoretically I should be able to add an "id" attribute to TestHomeView.mxml, but FB gives me an error: "id is not allowed on the root tag of a component". The root tag is s:view.
The reason I need to do this is that within another class I make various calculations and then need to pass an array of values to a component in my view class. So in SomeOtherActionScriptClass.as I first assemble the array, myArray, and then in that class I want to do this:
myViewComponent.viewArray = myArray;
If I'm going to do that, I also need to import the view class into the .as class, which strikes me as weird. So is there a simple way to do what I want, or do I have to dispatch a custom event which contains the array, and listen for it in the view class?
EDIT - Based on the below MVC suggestion I did the following in model:
[Bindable]
public class Model
{
private static var myModel:Model;//doesn't let me name it 'model' because
[code].....
But it is coming back null. It isn't null when I put a breakpoint in the Model class, but when I try to access it from the view class, it's null. The model itself isn't null, but that variable is.

Right now all the sounds (78 of them) on my guitar play using the roll_over event but that doesn't give the user much control over what sound is played.
The actionscript im using to play my sounds is this;
for(var i:uint = 0; i < buttonArray.length; i++){
buttonArray[i].addEventListener(MouseEvent.ROLL_OVER, buttonRolledOver);
}
[Code]....
What i want to do is only play a sound with the roll_over event when the left click is held down.

In the Spark DataGrid the default row height is about 22 px. I would like to set the default row height to 18 pixels and I can do this easily enough with the rowHeight property but what happens is when the rowHeight is set to anything less than 22 px the bottom area of the text in each row is cut off. It seems that the default grid itemrenderer or grid label has a min height set to it. Since I have multiple columns and want to have shorter rows but not have the bottom of the text cut off in each row how would I do this?

Just wanted to ask if there is any advantage for either using mouse click event or touch tap events, when writing apps for mobiles or tablets (for the iphone especially)?
I know that both of them should work fine, but in term of performance, is anyone better? Are there any things I should be aware of when choosing either?
By the way am using actionscript3 to implement the app.

I have an animation that I want to start when clicking on the flash window. However, I've also have some buttons on the stage. If I add an event listener for MouseEvent.CLICK on the stage, then it 'eats up' the events and the buttons don't work.
I've tried some tricks, by adding some invisible buttons on top of the real ones, and use the MOUSE_OVER event to selectively enable/disable the mouseEnabled flag for the stage, but didn't work because it complains that the property or method doesn't exist (which I find odd).

We are building an interface for a game. The interface has a tabbed menu at the bottom of the screen, with each tab displaying different aspects of an object (called a node). When you click on one of these parts, it becomes the focus, and we download it's details in XML, including all it's sub-nodes and parent nodes and then update the tab display accordingly, or at least that's what we'd like to happen.
What we have:
MainInterface.mxml
<s:Application...
<fx:Script>
<![CDATA[
public var currentNode:Node = new Node();
[Code] .....
We tried adding an event listener for "selectNode" to the dashBoard:SkinnableContainer you see see above, but it didn't seem to want to take. We suspect this is because dashBoard is from a spark component and the dispatcher for "selectNode" is on of our own custom components, but we weren't sure... in any case that's what the code assist seemed to indicate as we had to write it in by hand. We're not sure how to pick up the Events in FlashBuilder 4's debugger, so we're having trouble working out where it's going wrong.
Basically, when someone clicks on the label of a child or parent node (that is displayed by the itemRenderer), we want a URLRequest sent to our website, with the url specific to the node clicked on. We then want a URLLoader listening for the return which will update public variable 'currentNode' when xmlDownloaded is called by the loader. If you could clarify how the click event should be dispatched, what should be listening for it then sending the URLRequest and where the URLLoader that is listening for the xml data to return should be that would solve our problems.

I am writing a flex application and I have two Spark TextAreas. I want to create an EventListener so that when the user clicks on a text area, the text inside the TextArea is cleared:
this.addEventListener(FocusEvent.FOCUS_IN, onFocusIn);
private function onFocusIn(ev:FocusEvent):void {
if (this._showsCaption) {
[Code]....
Currently I can implement this with a Spark TextInput, but when I click on the TextArea, the focusIn event never fires and the onFocusIn() handler is never called.

I have a bunch of potential random strings for recvStream.play("randomstring");then i have a timer checking every 5 seconds on a function that runs an event listener:
recvStream.addEventListener(NetStatusEvent.NET_STATUS,
netConnectionHandler);
then im thinking in a switch statement i can use it to check if it's an active stream or not to either have it search for another stream that should be active or stop the timer and let it play.
// i was thinking this would verify it's playing and then that's it
case "NetStream.Play.Start" :
trace("ITS PLAYING YOU SHOULD SEE SOMETHING");[code].....
//I also tried NetStream.Play.StreamNotFound instead of NetStream.Buffer.Empty didn't work either.But it really doesn't work like that. Is there something else I should be using instead of NetStream.Buffer.Empty ? Or something else all together? I'm using Actionscript 3 in Flash CS5 and I'm using Cirrus RTMFP

i have a question about the mouse down / mouse move events in Flash. I've developed a small intreractive that requires mouse co-ordinates to be captured when the mouse is down and when the mouse is moved anywhere on the screen. It was working fine like this until recently when I checked my interactive in Safari and it no longer recieves mouse co-ordinate information when the mouse cursor leaves the Flash interactive stage area.However, it still works fine in Firefox. Is there anything I can do to get this functionality back when using it in Safari?
