In Flex it is now possible to use the -define compiler option to do all sorts of cool stuff.In my program, I am using the option such that some of my code is excluded by blocks like this:
CONFIG::FACEBOOK{
//Some code
}
And this is working well.How do I get a similar behaviour with MXML?I want to do the same thing, but omitting/including MXML tags in this way, not blocks of AS code.
Does MXML get compiled down to as3 and then converted to flash bytecode? Also, is there a significant performance penalty to compiling mxml vs compiling as3?
View 3 RepliesI am trying to set some public static constants on a class conditionally by passing variables to the compiler e.g. -define=CONFIG::ENVIRONMENT,'testing_server'
[Code]...
Obviously this means I have to tinker with long command line setting each time. I thought my initial approach was possible given the documentation and various tutorials I have read.
how can I do the following in a Flex project?[code]then flash builder gives me a compile error:1018: Duplicate class definition: Main
View 2 RepliesI am trying to build an application which has a flex front-end and a php back-end. I am struggling to do something with this application which I couldn't figure out a way to do. I would want my flex application to show a view based on an MXML it recieves from the server as a response to some interaction in the flex application. for example, lets say there are two buttons on the current view and if i press the first button, it will load one mxml/as3 from the server, and when i click the other, it will load a different mxml. How do you think i can tackle this situation? how to do this as i've been banging my head on the wall trying to figure out a way.
View 3 RepliesIn AS3 you can pass a constant to the compiler -define+=CONFIG::DEBUG,true And use it for conditional compilation like so:
CONFIG::DEBUG {trace("This only gets compiled when debug is true.");}
I'm looking for something like #ifndef so I can negate the value of debug and use it to conditionally add release code. The only solution I've found so far was in the conditional compilation documentation at adobe and since my debug and release configurations are mutually exclusive I don't like the idea of having both DEBUG and RELEASE constants.
Also, this format works, but I'm assuming that it's running the check at runtime which is not what I want:
if (CONFIG::DEBUG) {
//debug stuff
}
else {

Is there a way to compile SWC files in different targets (Debug vs. Release) similarly how you can compile a SWF file with the AS3 Conditional Compiler constants?
This link shows how SWF files can be compiled with predefined compiler constants:[URL]..
But I need to know how to achieve this with SWC files instead.
Note: I'm using FlashDevelop (Windows 7) to create the SWC (if that's any help to refine the answer).
I have to work with a .fla file. I would like to rewrite this file in AS3. Is it possible?
I mean, I would get a .swf file as result of compilation of mxml file in Flash Builder 4 IDE, not Flash CS5 (I don't know CS5, I'm a newbie) . Main target is getting a .swf file by compilation of mxml file, not fla file. Could you explain in detail how this code works? For example what's TXT ? Is it a inputText? Where is this variable defined?
Now I 'm linking .fla file ....

I am working on a custom Flex 4 component which is an aggregation of two existing flex components. I would like to be able to specify my own custom properties for the component as well as access the existing public subcomponent properties via MXML. For instance I might want to adjust the font color or style for the label and text input. toy component which aggregates both a label and a text input:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

View 3 RepliesIt seems it isn't possible at runtime to change styling defined in CSS files, ex.: colors. This is seemingly because the CSS files are compiled into SWF. Is it possible to externalize styling information in CSS (or any other format) without compiling it to SWF file so that it can be changed easily at runtime just as normal CSS can be changed when it is used in HTML.

Is there any way to speed up MXMLC compiles using Flextasks in Ant in Eclipse. Compared to FDT and Flex Builder's in-built compilation, it is painfully slow.

View 1 RepliesI'm having an odd problem that isn't mission critical since I can use the command line with no probs.In my earlier post http:[url]... I had problems getting the web compiler to work.Now that it's working I use this in a browser to compile: http:[url]...
and I get this error as a result:

Everything is legit and the most recommended solution is that the namespaces aren't correct. I've checked those and they're fine. Other answers I've come across relate to external components causing a problem but as you can see, I'm not using an external component.Here's the kicker. If I do a compile via command line:
mxmlc topsight.mxml
it compiles perfectly.Specs are still the same from the prior post and I'm using the Flex 3 SDK.Not sure if this would help but I did the download from http:[url]... and I clicked on the Open Source Flex SDK - Milestone 3.3
Is there a simple way to report the time necessary to compile an applcation in Flash Builder (in the Console or an external file) ?
I want to compare the average compilation time between the usual Flex compiler and HFCD (HellFire Compiler Daemon) for a given project.
I'm building a Flex/AIR application that connects to a remote server, the URL of which changes depending on the environment (development/production, and possibly others). For now, this URL parameter is hardcoded in my root application MXML file but it means I have to change it everytime I build my app for a different environment.Is there a way to externalize such a parameter so that when Flash Builder automatically builds my app (in development mode), it uses the development URL
View 1 RepliesI have a web application written in Flex and I'm trying to build an AIR application from the same code base using conditional compilation.
In the AIR application, I need to have import statements such as the following: import flash.data.SQLConnection; import flash.filesystem.File; but I cannot have these import statements in the web application because they are AIR only classes.
[Code]...
and similar approach to include web or AIR specific functions during compilation. The approach seems to have worked so far The only place I have run across issues is in my Cairngorm's model locator. If I put CONFIG::desktopMode around import statements in Cairngorm's model locator, it starts giving "Uncaught exception in compiler" or "1131 classes must not be nested" error. I'm not sure how to address this error!
A Flex components values are initlized by init methord. In an application flow, How to refresh a mxml component data value ; as init is callled at the start up it self only.
eg. of mxml componet may be as simple as button label or text as complex as repeater whose data provider is a web service ( means a fresh quesy should be made to pull the data and refresh the dataprovider of repeater )
suppose i have 3 buttons(for example say, productin, marketing, sales ) on my main.mxml..once i click on one button it should take me to abc.mxml page with production data, once again if i click on second button it should take me to the same abc.mxml but with marketing data. same as for 3rd button also, how can i achieve this ?
View 2 RepliesI moved from using the Flex Builder 3 IDE to Flash Builder a couple weeks ago and have noticed a ridiculous jump in compile times with the same project. It almost seems like every time I build it does a clean build. The project I am working with is pretty big, but when it takes more than 4 mins to build, something is wrong. I tried adding more memory to eclipse and all the tricks I could find on the web but the compile time never really changed. I am running under Windows 7 32bit, and I get the same performance from the plugin and stand alone version of the IDE.
View 2 RepliesI've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?
This is a project I'm working on for a simple demo tutorial application in Flex. I am using mxml pages.

first one shows playheadtime of videodisplay and another is also used for same purpose. the difference is that when we are in add mode(decided from a flag variable) both should show current playheadtime using binding. but when we are in edit mode(again decided from flag) the latter label should remain static, to be more specific, the value retrived from database.how can I do that using actionscript.
