I want to know when the data has been added to a chart so I can use localToData() to draw on the chart. If I do this immediately after setting the dataProvider the chart has not yet updated, so the the call to localToData will not return the correct values. Is there an event I can subscribe to so I know the chart has drawn the data in the dataProvider?
View 2 RepliesCan event listeners only be added to the class which dispatched the event? I ask because I want to have the logic for the listener on the main class, and the action is dispatched on click from a thumb which is instantiated in a scroller class. Kinda like this:
ActionScript Code:
pseudo code:
class main {
main() {
[code]....
This doesn't work. Why can't the main class listen for an event on the thumb class?
I have this slight problem with the event ADDED_TO_STAGE. The listener is launched twice so I figured the event is dispatched twice.
Here is my .fla code :
var section:SectionStructure = new SectionStructure("xml/list.xml")
addChild(section)
The Section Structure code :
[...]
mainHolder = new MovieClip;
mainHolder.addEventListener(Event.ADDED_TO_STAGE, displayObjects);
addChild(mainHolder);
} private function displayObjects(pEvent:Event):void {
mainHolder.addChild(sectionMenu);
}
[Code] .....
The output panel displays "test A" once and "test B" twice. I fixed the problem by adding this little line on the opening of the function createButtons :
menuHolder.removeEventListener(Event.ADDED_TO_STAGE, createButtons);
I read here and there that the event ADDED_TO_STAGE is dispatched when children are added but my problem remains even when I comment everything below this line :
trace("test B");
I have a Line Series Chart in Flex with values from 0 to 90. I would like to set the background of the chart in such a way that, 0 - 30 is in green, 31 - 60 is in red and 61 - 90 is in blue.
View 2 RepliesI have a line chart with a column chart as a secondary series. When I roll over the line, the datatips appear. However, if I move the mouse to a spot where a column appears while still on the line, the data tip item appears for the line AND the column. How do I get it so that I only show datatips for the line but not the column?

I want to show the second line series underneath the first one, however with this code they are appearing sequentially. Not sure how to make sure they are overlayed! I followed some code I saw for combining charts.. not sure what to do.

<mx:series>

The new series name appear on the chart, but the data doest, and the chart always remains blank.
I'm testing some event dispatch code in a Flex app, using FlexUnit's addAsync method for testing that events are dispatched. Great so far, I can ensure that at least one event was fired. However, I want to be a bit more detailed; I want to ensure that exactly the set of events I'm expecting are dispatched. Is there a useful test pattern (or, even, different test framework -- I'm flexible!) to accomplish this?I tried this code, but it doesn't seem to get invoked the second time:[code]
View 2 RepliesI want a chart that has several separate series running in rows across. They are largely separate charts and should not overlap, but all share the same horizontal datetimeaxis. They don't share the same y-axis, however and that's where I'm getting stuck.I have tried having a linechart series and then a plotchart series, but it will only allow a single <mx:series> per chart without having them inside the same series which as far as I can tell will place the charts on top of each other in the z-axis. I can stack them and have them completely separate charts, but it was proving to be somewhat irritating having them align correctly.
Is there any reasonable way of combining multiple charts into one like this? Basically having rows in a table where each row is a different chart but the columns are consistent. or am I going to be best served just by stacking separate ones? an illustration of what i'm going for is here: http:[url]........

I am trying to determine what events I need to wait for in a test in order to ensure that my custom component has updated all of its properties. I was using VALUE_COMMIT, but for some reason that isn't working out for me. I want some easy mechanism for tracing every event dispatched from a component. Is this possible?

I am currently working with a drawing tool for a mapping API, and every time I double-click the mouse a map service will perform a measurement and display the length of the line that I am drawing.
I want to mimic this double-click manually by dispatching a MouseEvent.DOUBLE_CLICK, but the map service is not listening to this default Flex event. I suspect that the API has created a custom MapMouseEvent or something like it that is being dispatched when a user double-clicks the mouse.
Is there a way to determine which event is being dispatched when I double-click the mouse?

View 9 RepliesThe app I want to build is an interactive map for a site I'm designing. In a nut shell, students looking to enter an exchange program should be able to use the map-image (as in, an actual 'map of the world') to preview possible destinations (I've attached an image of the two basic states to clarify).
After an introductory animation, I want a mouse-over to trigger a function that populates the map-image with a series of buttons. I need the buttons to be distributed according to information in an XML file (ie. x/y coords, some information text, and an animation to load upon being clicked). I want each button to call a mouse-over function that loads info data from an XML field and place it in a dynamic text field at the top. Then, I want each button, when clicked, to call a function that animates replacing the map-image with an image of the corresponding travel destination. Finally, I want a button on each image that will clear that image from the stage and call the function that populates the map so the process can start again.
I'm working out of a couple of books on AS3, but I'm a little hazy on how I ought to be constructing this thing. So here's the first place I've run aground: After the intro animation, I want the user to mouse-over the stage and have a second animation play (clearing away the introductory text), and I want the conclusion of the clearing animation to immediately call the map-populate function; but I don't want a mouse-over to have any effect until the introductory animation is finished. Is there an event dispatched automatically at the end of an animation? What is the event listener class?
I'm not sure if I should be storing each of these animations in an independent .fla file or if I should create them on all one timeline and have the program redirect to specific frames.
i have a question to ask about asynchronous key controls This was what i did
[Code]...
and i checked with [URL]...?newspage=6249 and it looked more or less the same, so why is it that when i move my character and when i hold down a key, it just keeps on listerning to that keypress event listener, instead of just executing the other event. So say, i tap left and after which i tap right, it will work just fine, but if i hold left and tap right, the event listerner will still be listening to the left key. So, i was wondering could anyone point me in a direction as to how should i make my code stop listening to an event as soon as another event has been dispatched?
I am looking for an event which is fired (if any) after a chart is rendered (visible in UI) in Flash, we are using Flex SDK 3.0. We have to capture the screenshot after the chart is rendered, current implementation adds a huge delay in update_complete event callback, this is slowing down the whole job of generating images. I tried to use EXIT_FRAME event, but this doesn't seem to serve the purpose.

View 1 RepliesI have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.

Let's say you have a guestbook in where you constantly update the data pulled from a .txt file, but when someone posts a comment and press the SUBMIT button, you'd like that the data is updated at that moment to make it display faster, but since an already dispatched event is coming to update the data of your guestbook WITHOUT the newly posted comment, a flicker might occur, so you would then like to stop that data from being transferred to your Flash file and rather dispatch a new event to load new data with your recently posted comment. Or maybe you just want to know how to stop an event from any class, either way, you've come to the right place.
Let's use that guestbook as our example. Instead of using an onEnterFrame to constantly update the data, I'd use LoadVars' onData event to retrieve the data, but when that data has been transferred, dispatch another onData event, and make this keep going in a loop:
ActionScript Code:
function updateGuestbook(){
loadData = new LoadVars();
loadData.onData = function(data){
[code]...
and then I have this button to submit my comment to the guestbook (keeping it simple):
ActionScript Code:
submit_btn.onRelease = function(){
loadVariablesNum("somefile.php", 0, "POST");
updateGuestbook();
}
so I call the updateGuestbook function, which will fire another event to load new data, but another event has probably already been fired off already with the old data, and this will cause the guestbook to nudge a bit, flicker, if you know what I mean, because first the old data will load, then right after that, a few milliseconds later, the new data will load, and this will be visible to the eye, and will probably not look good.What you can do, is to stop the previous event, delete it, to stop its data from being received by Flash. To do this, simply use this:
ActionScript Code:
delete loadData.onData;
to delete that event, just as simple as that.
ActionScript Code:
submit_btn.onRelease = function(){
loadVariablesNum("somefile.php", 0, "POST");

How would I check if an event has already been dispatched or not?
Is it as simple as checking the "target" property if it's null or not? Or are there cases when the target will be null, but it still has already been dispatched?
