[flexcoders] Challenge in Migrating to HTML5 from FLEX.
Hi Team, I have a question on migration from FLEX to HTML5. This question may be little out of the discussion in here; It would be great if someone help me out. I have a java server side application. It had a class that exposed a bundle of routines that are needed for the flex front end to drive the backend. I connect this class using with blazeds and get access to all the routines within and able to work just fine. It worked like a charm and everyone was happy till date. Now, I have a parallel requirement to build a HTML5 equivalent front end that does the same. I am asked to provide a estimate and possible frameworks that can be used with ease. Can someone put down any views if they have. Thanks. Scenario. Java back end remains the same – Build an interactive HTML5 webpage just looking similar to my current flash version - there is a submit_button() java routine which I have to call when a button on HTML page is clicked – Web server used is Jetty – Please Comment! Thanks!! Cheers, Venkat.
Re: [flexcoders] Timed Progress bar for 2 minutes.
My application will try to connect to a java framework, which in turn calls some scripts to execute on a server. If it is a firmware update script that is called, it will typically wait for 2-3 minutes before the update on the server is complete. So I have to keep user understand that process is going on (or else, they may think the system is hanged or not responding with 2 minutes of spinning), to provide some understandably, I am thinking of static pooling a progress bar for 2-3 (standard time which we know) minutes that looks more user friendly. What say? Cheers, Venkat. From: Paul Andrews p...@ipauland.com To: flexcoders@yahoogroups.com Sent: Tuesday, January 10, 2012 4:13 AM Subject: Re: [flexcoders] Timed Progress bar for 2 minutes.

A spinning animation might suit you better, keep it spinning until the load is done. It would just look like the application had hung. As Rick suggested, two minutes is a very long time. What is it that takes two minutes to be ready? If it's a database query, I'd suggest sorting out the server, because two minutes is a ridiculous amount of time to be waiting for a result. It really looks like your application has a fundamental problem.

[flexcoders] Flex to HTML5 Conversion tool?
Hi Group, I have a quick question. I have a web application that was developed using 100% flex (AS included). Now to be on the safe side we want to evaluate the options of converting the same on to HTML5. Do any one know of any tools that can help in the process of converting from flex (developed) to html5 version? Your help will be greatly appreciated. Cheers, Venkat.
[flexcoders] Calling flex from JavaScript wrapper
Hi Team,
I have a question
about calling a flex method from JS.
The
scenario is, if the user closes the window without logging off, I detect the
window close from JS and call the appropriate logoff mechanism which is mapped
originally for log out button.
JS code
SCRIPT LANGUAGE=JavaScript
window.onbeforeunload = clean_up;
function clean_up()
{
var flex = document.${application} || window.${application};
flex.myFlexFunction();
}
And in the
Flex application I code –
import flash.external.ExternalInterface;
ExternalInterface.addCallback(myFlexFunction,cleanUp);
public function cleanUp():void{
//do the dirty work
.
This codes
are taken from http://board.flashkit.com/board/showthread.php?t=748226
But I find
no action being detected. My html wrapper for the application has no visual
elements. The whole functioning of the application is entirely in flex. The
HTML is just a wrapper for it.
Its not
working for me. Any views?
Cheers,
Venkat.

[flexcoders] Bar Graph basic doubt!
Hi Group, I have a basic doubt on bar graphs in flex. For a bar graph I bind the data provider with an array collection. This array collection will be populated dynamically with the values 0,1 or 2. So the bar graph is showing fine, but the interval lines are at 0, 0.2,0.4,0.6,0.8,1,1.2,1.4,1.6,1.8,2 meaning: at intervals of .2. I want it to be only integers, meaning: 0,1,2 that’s it. How do I do it? Please help. Thanks Best Regards, Venkat.
Re: [flexcoders] Module Structuring
You can actually use the module unload and load of the module loader class on a single event. In the vent handler of the click you just figure out the child element of the module loader class and if it is not null just unload it and continue to load the module of choice in the newt line in the same function. It works! Skinning with modules: You are having the whole of skinning within the module compiled swf, so I believe on on unload everything is reset. basically it don't exist from a VM stand point of view.

Re: [flexcoders] Array to XML?
Hi,
My situation is I have a heavy array, named source.
Source has elements in the order [CA,12,25,35,40,
WA,23,43,54,65,
FL,26,46,14,69,
TX,03,83,55,15,
IL,21,49,84,95]
So basically the source array elements are in the order of: A state name then
four properties and then again a state name and four properties and so on.
I can’t hard code anything other than first one is a state name and will have 4
properties. The values in properties are dynamic.
I want to display this in the form of a tree in flex. Can I do it. If so,
please help. Thanks.

Venkat Maddali.

From another point of view… “A” could be thought of as an array… an object

Likewise, “B” could be thought of as another array.
