mx.preloaders.Preloader - Guide de référence du langage ActionSc

Recently during some framework development we needed to create a custom preloader that played nicely with the main Application. Implementing this functionality will be covered in a later post, but for time being this entry is intended to illustrate in detail what is going on during the load process. Preloading in Flex 3 can either be very easy or very complicated depending on the level of control you require. Obviously vanilla applications can use the default system and need no extra work, but implementing custom preloaders that have more complex functionality (visually or behind the scenes) can take a little while the first time round. The classes involved Firstly, due to the slightly confusing naming conventions used in the classes involved with preloading a few definitions are useful:

This article is written more than 2 years ago and it still receives a lot of interest. Technology has changed a lot in the last two years - Flex 3 transformed to Flex 4, etc. So I think, this article now needs a working sample demonstrating the approach below is still working. I’m not going to define and discuss what a RIA is, but I rather stress here on one very important aspect of rich internet applications and in particularly saving time . Time is money (or opportunities for pleasures and entertainment), having more time is having more money (or opportunities for pleasures and entertainment), so that’s where ‘rich’ comes from. http://npacemo.com/wordpress/2008/07/06/flex-application-bootstrapping-totally-custom-preloader/

Of course Flex's Loading animation is excellent, I think. but looking at the default animation day by day, I want to get some fresh air, so I decide to know how to draw it myself. Here is a single sample: //customize preloader //mxml file <?

volia je pense avoir compris qq truc (il est tps ) alors je vous en fait part , car ca peut servir . pour modifier le preloder j'ai décider de de faire une sousclasse de DownloadProgressBar on peut aussi par implementation de l'interface IPreloaderDisplay (d'apres mes lecture cela serait plus propre que d'ajouter d'overrider des methodes de DownloadProgressBar). mais bon par simplicité j'ai choisi la methode sous classe de DownloadProgressBar. en fait tout reside ds une bonne comprehension de la POO et de ces avantages ainsi que d'une bonne connaissance des classes et interfaces du framework (flex ). la solution que j'ai choisie est overrider la methode: createChildren() et setProgress(completed:Number, total:Number) de DownloadProgressBar pour pouvoir ajouter mes composants graphique et c'est tout ca fonctionne et j'affiche pdt le download le % et j'ai compris. http://www.flexx.fr/forum/topic1531.html#p5966

Flex Preloader: Créer un Preloader personnalisé - Adobe Flex Tut

http://www.flex-tutorial.fr/2008/05/29/flex-preloader-creer-un-preloader-personnalise/ Par défaut, toutes les applications Flex utilisent un preloader standard avec une barre de progression (progress bar) pendant que l’application elle-même se télécharge. Le chargement standard comprend tous les aspects du préchargement, y compris les shared libraries, les polices, et toutes les classes utilisées dans les modules. Enfin, il s’occupe de l’initialisation de l’application Flex. Si vous créez une application RIA pour un certain client, tous les détails compteront.
The application containers support an application preloader that uses a download progress bar to show the download and initialization progress of an application SWF file. By default, the application preloader is enabled. The preloader tracks how many bytes have been downloaded and continually updates the progress bar. The download progress bar displays information about two different phases of the application: the download phase and the initialization phase. The application container’s creationComplete event dismisses the preloader. Flex includes two download progress bar classes: the SparkDownloadProgressBar (Spark) and the DownloadProgressBar (MX). http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7e3c.html#WS2db454920e96a9e51e63e3d11c0bf62d75-7fee
