I am working on my first Adobe Flex application, and have a code section that appears to be running very slowly (but it does function properly!). CC_Output is a text control, all the other controls are checkboxes (CC, CC_Duration, etc.)[code]
View 3 RepliesI am wanting this to improve the initial download speed of the page. I have already added a Poster Frame to video's, however it still seems to be loading the video file and just autoplaying. Is there a way to NOT load the video file until the person hits play? This is the AS3 script I used...
import fl.video.VideoEvent;
myPoster.addEventListener(MouseEvent.CLICK, playMovie);
function showPosterFrame(event:Event):void { myPoster.visible = true;}
function hidePosterFrame(event:Event):void { myPoster.visible = false;}
function playMovie(event:MouseEvent):void { myVideo.play();}

View 3 RepliesI am working on a flex application. The application occupies 100% of the browser screen, but it is slow to load. How should I improve the performance, what are the best techniques one should follow for improving the performance of a flex App. I did try some stuff though, I am not using relative layout instead i am using absolute layout and putting the buttons/images etc at exact places in a Canvas, still i feel it is slow. Can I profile the App or flex code to see where exactly the app is taking the maximum time to execute.
View 3 RepliesI am using the Open source PurePDF library in my Flex AIR application. The problem is performance:It takes 100% CPU usage and too long to generate a PDF.
I have done some analysis on it and find that the text writing in pdf is expensive. That's why I need to know how I can improve the performance. Are there any fonts for which pdf generation is less expensive, or is there some setting or tip that can make this process somewhat better in terms of performance? secondly in case of images the ImageElement generation is very expensive when writing that element to PDF. Is there any way to reduce the processing?
I found a way to reduce the ImageElement generation processing by resizing the image using flex and by then passing the small image's bitmap data to the image element. It works fine, and i have reduced the time of execution to a good extent. is there any way to tell PDF to work in chunks or divide the work in such a way that it may take more time to complete but won't block the GUI while the PDF is being generated?

View 1 RepliesBackground: I am using SQLite database in my flex application. Size of the database is 4 MB and have 5 tables which are
table 1 have 2500 records
table 2 have 8700 records
table 3 have 3000 records
table 4 have 5000 records
table 5 have 2000 records.
Problem: Whenever I run a select query on any table, it takes around (approx 50 seconds) to fetch data from database tables. This has made the application quite slow and unresponsive while it fetches the data from the table.
How can i improve the performance of the SQLite database so that the time taken to fetch the data from the tables is reduced?
Multiple axis creation via MXML works fine:
http:[url]...
But when I'm trying dynamically create horizontal and vertical axis then I'm getting extra axes. I believe this is Adobe bug. How I can fix this behavior?
<?xml version="1.0" encoding="utf-8"?>
<s:Application
minHeight="600"[code].....
I have some shared code between an Adobe AIR App and an Adobe Flex App.
On one line of this code, the program must behave differently depending on if it is running within the Air runtime, or the Flex runtime.
How can I programmatically detect the difference?
For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?
View 1 RepliesI want to add an animated .gif file to my movie. So I created a new symbol and then imported the .gif file to the stage. This created the symbol containing the animated .gif.I dragged the symbol onto the scene where I want it. However, the animation seems to play at a different speed (fps) than normal. So I changed the fps of the symbol (at bottom of Timeline where it says "fps"). But for some reason this changes the fps of the rest of the entire movie.
View 3 RepliesI'm tweening a movieclip from startX to finishX. The value of startX varies but finishX is a constant. But as the startX increases in value the animation appears to be quicker. How do I adjust the speed of the tween to ensure a consistant speed regardless of the value of startX?

View 2 RepliesI'm using the SpinnerList component in a flex mobile application, the spinner turn too fast for my need, is it any way to reduces its speed.
There is many answer regarding the speed of the mouse wheel but no answer concerning the spinner itself.
I have a movie clip on my scene which has a speed applied to it making it move across the screen. This is duplicated when it reaches the other end of the screen.On my scene I have some action script which is acting as a timer. After a set time I want it to increase the speed of the movie clips, making the game become "harder". I seem to be able to manipulate the alpha of my movie clips but can't seem to trigger the speed increase.If i use a setInterval it seems to trigger the speed increase but it does it each time the movie clip is duplicated (so the delay resets, it does not change once and apply throughout)However, where I am changing the alpha I cannot seem to change the speed.

View 9 RepliesI'm using a lineseries chart, but it gets fairly slow to re-render when I add a new point when the total # of points is ~1200 points. Granted, this is running on a fairly slow PC (~600 MHz). Reading the Flex documentation on how to speed up rendering (turning off dropshadows, turning off filterData, etc...) doesnt seem to help. I bound my chart to an ArrayCollection (rather than the array I used before which I manually updated) and it doesnt seem to be any faster. Adobe's documentation seems to have me believe that the Chart looks only at what changed since the last time it was updated, but i'm only adding one point!
If their info is correct, why does it take significantly longer (5 seconds) to update one point when I have ~1200 points then when I only have 2 points (instantaneous)? FYI - When I add a new point to my ArrayCollection, I have to do a "AC.refresh()" to get the DataBinding to pick up the new data.

I have a component extending a Spark List, and when I scroll using the mouse wheel it scrolls too much in one go. I have tried looking for the handler that deals with mouse wheel scrolling in the List class and VerticalLayout class to override but I cannot find it.
