Preloading components

I'm trying to preload a component but I'm not having any
success. I dragged a datagrid onto frame 3, checked "export for
actionscript", unchecked "export in first frame" and exported my
classes to frame 2. Everything works great (frame 1 < 3KB) until
I give the datagrid (or any component for that matter) an instance
name. Then frame 1 jumps to 32KB and frame 2 is < 3KB. Any
ideas?

If I understand you correctly, it's not instantiated through
code. I dragged an instance of the component to the stage on frame
3 and gave it an instance name in the properties menu.

Preloading Components Breaks Them

I am creating a Flash presentation that uses quite a few
components (UIScrollbar, Checkbox, RadioButton, Button,
ScrollPane). Now because I want to be able to have a preloader that
works properly, I have changed my Publish Settings to set "export
frame for classes" to frame 6 (The frame after the preloader). I
have also gone to each of the components in my library, opened the
linkage settings, and unchecked the "Export in First Frame"
checkbox.
Now when I test my movie, the components do not work. For
instance, the UIScrollbar does not display the Arrow buttons (nor
does it work at all), and the scrollpane's dimensions are not what
I have set them to be in the movie. If I revert the settings back
to export on first frame and export frame for classes back to 1,
everything works fine.
Anyone have any ideas?

I took advice from another forum and decided to separate my
preloader and presentation into two different SWFs.
For those who may be interested, I used the MovieClipLoader
class to load my movie into a container clip in the preloader. I
had to adjust my preloader which was using the getBytesLoaded and
getBytesTotal to use the class's function onLoadProgress to animate
the progress bar.
I also had to go through and adjust buttons that referred to
movie clips on the root layer. Because I loaded the clip into
another movie, those clips were no longer on the _root layer. They
were on the _root.containerMC clip layer.
After these adjustments, everything worked fine. I can also
reuse my preloader for any other presentations for which I might
need a preloader. Thanks for the help.

Preloader help

can someone please help me out setting up my preloader... ive
got my main scene and scene 2 which is for my preloader... im just
looking to use one of the preloader components-- i dont want to
make one.... ive created a layer in scene 2 and placed the
preloader there---now how do i script it to go from scene 2 to my
movie...ive ooked at the tutorial's and it still confuses me...
again ive got scene 2 for my preloader and scene 1 which is my main
movie...
im looking to use not only a progress bar component... but
possibly a byte's loaded as well if that is possible...if that's to
much of an issue then ill just use the progress bar component..
ive got multiple progress bar components:
the byte's preloader set
a customizable load bar component
fr16 preload component
the flash ui components set
and the loader component from kirupa.com
im just looking to place the script...if you've got a sample
file please let me know; so, i can download and take it apart to
understand how it work's...
trey
if by chance you do a sample file-- either post it here or
email me @ [email protected]
thanks for your help...

Thanks for the assistance. I managed to get it figured out.
Corrected the target paths (listed below):
stop();
_root.holder_mc.loadingBar._xscale = 1;
var loadingCall:Number = setInterval(preloadSite, 50);
function preloadSite():Void {
var siteLoaded:Number = _root.holder_mc.getBytesLoaded();
var siteTotal:Number = _root.holder_mc.getBytesTotal();
var percentage:Number = Math.round(siteLoaded/siteTotal*100);
_root.holder_mc.loadingBar._xscale = percentage;
_root.holder_mc.percentClip.percentDisplay.text = percentage
+ "%";
trace("Percentage is Working");
_root.holder_mc.percentClip._x =
_root.holder_mc.loadingBar._x + _root.holder_mc.loadingBar._width;
_root.holder_mc.bytesDisplay.text = "loaded " + siteLoaded +
" of " + siteTotal + " bytes";
trace("Site Loaded is Working");
if (siteLoaded >= siteTotal) {
clearInterval(loadingCall);
gotoAndStop(5);
Text field was visible, font just needed to be embedded. As a
note I placed a dynamic text box that spec'd _sans as the font with
the 'use device fonts' option picked. I had to respec a different
font and embed it into the swf.
Thanks again for the assistance!

Preloader in Flex Components

Hi,
Is it possible to have preloader in flex components. For
example if we have a datagrid which fetches values from xml on load
thn how can i put the preloader in that datagrid. Please suggest.
Regards,
Naveen

Hi savz,
You can do the following...Try to embed the custom swf cursor in a variable and write a function in the preInitialize event of the main mxml application i.e; on the root tag <mx:Application preInitialize="onPreinitialize()"> </mx:Application>
[Embed(source='assets/swf/Preloader.swf')]
[Bindable]private var customCursor:Class;
private function onPreinitialize():void
StyleManager.getStyleDeclaration("CursorManager").setStyle("busyCursor",customCursor);
That's it you can go with it...As and when the busyCursor is true your customCursir is shown overriding the default busy curso symbol.
Please kindly mark the answer if it helped you..:)
Thanks,

PreLoader for V2 Components

I am using a large number of V2 components in an application.
I have created MovieClips that contain the V2 components and
written classes that I attach to these MovieClips. The classes
contain a fair amount of code to retrieve data from the web,
perform calculations on it, format it, and then place it in the V2
components for presentation.
When I test the application on my machine (i.e. no
downloading required over the internet) nothing appears until all
of the calculations in the classes are done, which takes about 15
to 20 seconds.
My question: Is there a way to have the calculations run in
the "background" while I provide an animation to amuse the visitor
until all of the calculations are done. Then I would present V2
rich MovieClips populated with all of the data.
I tried loading all of the V2 Rich MovieClips with _visible
set to false. Then, once all calculations were done I made the
clips visible. Although this works, as far as displaying the
Movieclips quickly with all of the calculated data, I still can't
provide a simple animation while the calculations are going on. The
animation stops while the calculations and formatting in the
attached MovieClip classes are being performed.
Can anyone point me to a tutorial that might address my
problem. Or am I just up against the wall on this one? It seems
every time I try to use V2 components I run into this problem even
without the linked classes. I've tried loading the class files in
frames other than the first frame, but it doesn't seem to make a
difference.

I don't think you can put a pre-loader on streaming video.
Although I'm not an expert. I would suggest a couple things though.
1. That quicktime is way to large. If you expect anyone to
wait for it, you're probably expecting too much. I've been waiting
for 5min now and nothing.
Solution: Have a smaller version of the file, and a link to
the high rez. That way, they get something, and can "download" the
high rez if desired.
2. You said you wanted to keep the QT higher resolution.
Well, Flash was built for internet bandwidth. You could convert to
FLV while maintaining high resolution. Do some testing and go with
what looks the best.
You could also mess with the frame rate. Cut the frames in
half, while maintaining resolution, and change audio to mono. That
should cut your file size down quite a bit.
3. If the above solutions don't work for you, try a having it
load in the background. You could have the site load first, and set
the parameters of the FLV playback to "Autoplay = False"

JavaFX - Image preloading problem

Hi,
I try to use ImageView and face some problems with image preloading.
Here is the code related to the component that has problems. The component extends CustomNode.
in class attributes declaration:
var imgNodes: ImageView[];
// list of url of images to display
public-init var imgs: String[];
in create function:
for(indice in [0..batch]){
var view= ImageView{
fitWidth:100
fitHeight:100
translateX: (110 * indice)
preserveRatio: true
cursor: Cursor.HAND
insert view into imgNodes;
on an image loading function:
for(indice in [0..batch]){
imgNodes[indice].image = Image{
width: 100
height: 100
url: imgs[firstItem+indice]
preserveRatio: true
backgroundLoading: true
with backgroundLoading set to true, the images are not displayed. When setting it to false, the images appear. So the urls passed to Image are ok.
If I display the fields error and progress of the Image components, both have the value 0.
I have other components that use preloading and they are working great before showing the problematic component. After, preloading does not work anymore.
It looks like as if the thread used to preload images is blocked.
Can anyone help me with it?
Thanks in advance for your help

Flex components not compatible with iOS/ADT packager?

I've been struggling hard and long to export a simple Hello World project to my iPhone with AIR 2.6. After a lot if reading on different blogs and sites I've gotten as far as packaging my debug swf to an IPA with ADT. The app starts on my iPhone but freezes during the preloader. If I change my main file to a strict AS3 file extending a Sprite it runs fine. Haven't been able to get startTouchDrag to work but I don't know if that has something to do with this problem.
I've tried:
Compiling with Flex 3.5, 4.0 and 4.1 (all merged with AIR 2.6 ofcourse)
I've tried setting the project to Flex 3 compatible (when using 4.0 and 4.1)
I've tried using MX components only.
Am I banging my head against a wall here or is it possible to package Flex applications or do they need to be strict AS3?

Hi Jeffrey
Thank you for replying! I will try Burrito when I get the chance.
I'm using iOS 4.3 on an iPhone 3GS so that shouldn't be a problem. I package with the AIR 2.6 adt and the swf is compiled in FB4 using Flex 4.1 merged with Air 2.6. I changed the main mxml file to an AS3 and now it runs on my iPhone but I can't get the TouchEvents to work. I get true when I trace Multitouch.supportsTouchEvents but I get no events when listening for TOUCH_BEGIN or TOUCH_TAP on either stage or a sprite. I've also added -target-player=11 as and additional compiler argument in FB4 (from Cantrell blog).
Is there something I might need to add to my adt packaging?
C:\AdobeAIRSDK\bin\adt -package -target ipa-test -provisioning-profile HelloWorld.mobileprovision -storetype pkcs12 -keystore rs.p12 -storepass XXXXXX ./HelloWorld.ipa ./bin-debug/HelloWorld-app.xml -C ./bin-debug HelloWorld.swf -C ./bin-debug assets
Should there be any files in the assets folder that I'm missing or anything special in the main-app.xml file?

Text not displaying on components

I have one swf file where im using the default textInput and
button components. Just so the user can enter a zip code and click
submit. When i publish that swf, everything looks fine. The problem
is that i am loading that swf into a master swf and when i view it
through the master swf, it displays the components without text.
The submit button is blank, it should say 'submit' on it, and no
characters display when you type into the textInput component. I am
able to type characters and submit the form, but i can't see what
im typing. I've tried messing with embedding fonts in the child swf
as well as the master to no avail. If anyone has any suggestions,
they would be greatly appreciated.

Here's how to talk to your dynamic text box. Where you put
this bit depends
on how you are building the preloader, but since you say the
progress bar
works fine, I'll assume you know what you're doing there and
will be able to
get this in the right spot.
// variable that calculates a number for the percent loaded
preloaded = Math.floor((loadedBytes/totalBytes)*100);
// this line is talking to a dynamic text box named
"percentage_txt" that is
inside a movieClip named "preloader_mc" on the root timeline
// depending on your setup the path may be different, but
make sure
everything on the way to the text box is named
_root.preloader_mc.percentage_txt.text = preloaded + "%";
// You've probably left out the ".text = " bit. Just a guess,
but that's
the bit I always find
// I've left out when I'm having trouble with dynamic text.
// Also make sure your text color is not set to the same
color as your
background. Duh.
Good luck.

Preloader Not Displaying In Simulate Download - White Screen

Hello:
I followed a tutorial on gotoandlearn.com and followed it to a "T," yet cannot troubleshoot this myself. I built a simple preloader in AS2, but when I simulate the download for a Flash website in Adobe Flash CS4, all I see is a white screen, then it continues to the website. I previewed the bandwidth profile and I can see that it's working it's preloading magic; I just can't see the animation.
I looked through numerous forums and I am not using an components that are exported to the first frame -- at least that I know of. Has anyone experienced the same issue?
My set up is the following (from Lee's tutorial):
First Keyframe (action):
var amountloaded:Number = _root.getBytesLoaded()/_root.getBytesTotal();
preload._width = amountLoaded * 190;
loadText.text = Math.round(amountLoaded * 100) + "%";
Second Keyframe (action):
if(_root.getBytesLoaded() == _root.getBytesTotal()) {
gotoAndPlay(3);
else {
gotoAndPlay(1);
Third Keyframe:
stop();
Any thoughts? Thanks!

I'm still seeing a white screen
I changed my code as you said to:
Keyframe 1 (actions):
var amountloaded:Number = _root.getBytesLoaded()/_root.getBytesTotal();
preload._width = amountLoaded * 190;
loadText.text = Math.round(amountLoaded * 100) + "%";
Keyframe 3 (actions):
if(_root.getBytesLoaded() == _root.getBytesTotal()) {
gotoAndPlay(5);
else {
gotoAndPlay(1);
Keyframe 5 (actions):
stop();
Also, what's NaN%? I'm not able to view the progress bar at all, because all I see is white, but I navigated through my site and accidentally returned to frame 1, and the progress bar read "NaN%."

Preloader problem

Dear,
i have a problem in my preloader, i have 2 scenes, first one
the preloader and the another is the content of the site ( 10
frames )
the preloader start showing the loader in 56% not from 0% so
the user have to wait from 0% to 56% with blank stage.
even though, if i used the same preload but in only 1 frame
in the content scene its will work great.
i don't load anything from external movies, all my content in
one scene...
Thanks a lot...
my code:

Oh. You have so many things wrong with this project.
First unless you are publishing to Flash 5 you shouldn't be
using onClipEvents(). That was a style of coding that went out in
2001 when Flash 6 was introduced and has a lot of drawbacks and no
advantages. (Well unless you need to publish to Flash 5!) Here is a
really good blog on the issue:
http://www.quip.net/blog/2006/flash/museum-pieces-on-and-onclipevent
Okay the next issue is that you really shouldn't use scenes.
They were a great tool to help timeline animators organize their
content. But when you start to use code it starts to breakdown.
There are several tricky little problems that crop up when you
start using code that moves the playhead and scenes. So it is
better to not put them on scenes. Instead just put your first
"scene" on frame one. And then maybe move over to frame 100 and
start your second "scene." When you publish your swf all the scenes
are strung together in one long timeline and the "scenes" are gone
per se.
Next issue is the one you actually are asking about. All the
content in frame 1 (the actual frame one after all the scenes are
strung together) must be loaded before any code on that screen can
start to execute.
So if you have any components, even if they are only in the
library and you aren't using them, will put a lot of content into
frame 1. If you have a bunch of library assets set to export for
actionscript those usually are in frame one as well.
Otherwise, you can go to the publish settings and switch to
the flash tab. There is a check box for generate a size report.
When you publish you will also get a text file that shows you how
much content is in your file and where it is.

Preloader Delay

I noticed in the manual that the preloader for Flex apps have
a 700 millisecond delay. This isn't very significant... but you can
see the screen flash my not-yet-formatted components on the screen
during this time. Is there a way to adjust the delay to 0?

Another way to solve this issue would be to go to the Publish
Settings, click on Settings next to ActionScript 2.0 and set the
export frame for classes to 2.

Preloader not working when image scroller present

Hi:
I designed a .fla that involves a large panoramic image that
I stitched together in PhotoShop, then imported into the library
and made into a movie clip, I then have the movie clip of the
panoramic load into an image scroller (the one in the components
library) on the main timeline so you get the sense you are panning
through the photo. Within the movie clip of the panoramic there are
buttons in it that then call other movie clips to load another
movie clip on top of the image scroller.
code attached to the buttons is:
on(release){
_root.attachMovie("myMovie", "screen",1);
_root.screen._x =10;
_root.screen._y =425;
My issue is the file is so large that I have made created a
preloader.
If I load the movie clip of the panoramic directly onto the
timeline the preloader works fine...
When I try to load the imagescroller that calls the movie
clip my preloader does not work at all...
Does anyone have any ideas?
I will gladly supply you with any code you may need.
Thank you
Janalese

Thank you for your information. It worked great as far as...I
could build a preloader and have the movie show up on the screen as
I wanted. Now for problem number two that has developed...
The MovieClipLoader that calls external .swf file. This is a
movie that has an image scroll bar that calls a movie clip that
scrolls a panoramic photo. Within that movie clip of the panoramic
I have buttons that then call other movie clips from the library
using
on(release){
_root.attachMovie("myModelScroll", "screen",1);
_root.screen._x =10;
_root.screen._y =425;
This is an example of what I am doing
I have a panoramic shot that is in an image scroller, that
panoramic is of a group of buildings each building has a button
next to it. Those buttons then call up another movie clip from the
library using the attachMovie clip to show another mini movie clip
of what the building looks like inside, and what the purpose is.
Issue:
The buttons within the movie clip that is loaded into the
image scroller fail to work. If I just load the .swf files into the
browser it works just fine...
but the issue is I have a huge file with an image scroller so
I need a progress bar and a MovieClipLoader function.
How do I now get the other code attached to the buttons
within the movie clip that says attachMovieClip to work within the
context.
I am so baffelled as to why it won't work...
Here is the code to my preloader and movieClipLoader
My actionScript skills are very limited so any help is
greatly appreciated but needs to be supplied in simple language.
Thank you very much

Preload works in firefox, not in ie

Hi all,
i create a swf called preload that load an external swf, it
works only with firefox and not in ie.
This is the code in preload.swf:
import mx.controls.Loader;
import mx.controls.ProgressBar;
this.createClassObject(ProgressBar,"my_pb",998);
this.createClassObject(Loader,"my_ldr",999);
my_pb.move(350,300);
my_ldr.move(0,0);
my_pb.source = "my_ldr";
var loadListener:Object = new Object();
loadListener.progress = function(eventObj){
// eventObj.target è il componente che ha generato
l'evento progress,
// ovvero, il loader.
my_pb.setProgress(my_ldr.bytesLoaded, my_ldr.bytesTotal); //
Visualizza l'avanzamento.
my_ldr.addEventListener("progress",loadListener);
my_ldr.scaleContent = false;
my_ldr.contentPath = "/files/movie.swf"+"?cvc=" + cvc;
where cvc, is a session coookie.
I have to do this preload, because movie.swf contain some
component that load an application in a flash media server.
Someone can help me?
thank you a lot.

I test your preloader, work fine with opera and ie , maybe
the problem is in your ie.Because here everything work good
:)

Flash builder 4.5 + mobile apps + mx components : error#1014

Hi everyone,
I found about the capabilities of Flex/Air a few weeks ago and I started experimenting. I'm interested in the mobile apps in particular.
I downloaded the final release of Flash Builder and started to "code" a few things (I am fairly new to ActionScript too).
The thing is I have errors when launching the mobile apps on an emulator or on my Desire HD.
Typical example is this app from Ryan Stewart : http://blog.digitalbackcountry.com/2011/03/slides-and-assets-from-adobe-refresh/
I tried to run his CollaborationMobile App (as I want to work with LCCS) onto a device emulator thanks to Flash Builder but I get the following errors :
VerifyError: Error #1014: Class mx.containers::Canvas could not be found.

Create cool preloader without flash?

Hi all,
Is there a way I can graphically design a preloader with just AI en Flex?
I've found tutorials online using Flash and pure AS3 to create preloaders, but it'd be very convenient if I could use Flash Builder and create a Preloader.mxml with some simple .FXG graphs.
Or maybe there's a way to generate a standard PreloaderSkin.mxml with FlashBuilder which I can use as a template?
Thanks!

Hi,
I had a bit of a play with preloaders, this is what I found.
1. A flex based preloader is no value as it won't work until the framework components are loaded, even if you start to add the needed libraries into a flex swc the file size becomes very large very quickly which defeats the whole purpose of a preloader.
2. Preloaders are happy to be constructed with any elements available in the flashplayer so you don't need a preformed flash based swc or swf as a preloader.
3. Its Easy to write actionscript preloader's in flex.
4. A preloader generator wouldn't be that hard to make maybe an air app with a visual designer that generates the requires actionscript file.
I am going to play with the visual designer idea after experimenting with preloaders that use a config file for 'skinning'.
