"Flex Library Project"

Just a terminological note - "Flex Library Project" should be renamed to just "Library Project". It has nothing to do with Flex Framework. You can create non-flex libraries. Now as Flex Builder has become Flash Builder, it is even more illogical.

Pavel,
Good point. Can you please file a bug/enhancement at http://bugs.adobe.com/flex.
Thanks,

How do I apply programmatic skins for completely custom drawn components of a Flex library project?

Hello folks,
I am looking for best practices advice when (1) creating
custom components and (2) styling and skinning.
I already know how to skin a component part of the Flex
framework. I can make a class extending ProgrammaticSkin and have
my component skinned using CSS to link the component with the
reference to my custom class.
However what about those cases when you are completely
creating a component from scratch?
Imagine a "Freehand Drawing Canvas" component that allows the
user to draw on it and has some buttons to set color styles, line
styles, etc., or imagine a "Screen Flow Gallery" component that
displays visual objects in a fashion similar to Cover Flow in the
Mac.
In many components I am aware you may reuse other components
part of the Flex framework but I am trying to picture an scenario
where you would need to draw everything yourself because there just
isn't something to base it upon so you will end up drawing it from
scratch.
To learn how instead of building one of those components I
mentioned previously I decided to start with something simple that
would illustrate this like a LiteButton component that will behave
just like the Flex mx.controls.Button but will extend UIComponent
and be completely custom drawn.
The component will have a default look and will also be
style-able and skin-able. I will provide styles for users of the
component to modify and regarding skinning anyone can create a
custom ProgrammaticSkin adding its own drawing logic and link it to
the component via CSS with the ClassReference applied to the skin
selector.
So far so good and it's clear what I want to achieve. I
actually know how to do most of the stuff here but I have one
single problem.
Here is my question, where should I put my custom drawing
logic? If I do it in the updateDisplayList inside the class
extending UIComponent it works, however I thought that it would be
a better practice to do it using programmatic skins, that way I
could provide different skin themes for my component set.
The problem is that I can't make the programmatic work in
this scenario. I tried instantiating the custom programmatic skin
during the updateDisplayList of the LiteButton component and adding
it to my display object via addChild but that didn't do anything. I
also tried creating a "default.css" stylesheet and tried to use
ClassReference as I would normally do to skin an already existing
component (or composite component as well) but that didn't do
anything either.
So how do I apply programmatic skins for completely custom
drawn components of my Flex library project?
I could do it inside the updateDisplayList of the LiteButton
class extending UIComponent but again I would like to provide
different theme sets for my components so it makes sense using
programmatic skins.

This may help with that

These aren't mutually exclusive. When you provide a skin with
a
TypeSelector, you have to add it to the display list
somewhere, and this is
typically done in updateDisplayList or addChildren. I prefer
to do it in
updateDisplayList, because you can then change it if the
style changes.

Exactly what did you do?

I've never had any problem using an approach similar to
this...but I will
say that I couldn't see any advantage in creating a
default.css style sheet,
since it's not really default in the way that the one that
comes with Flex
is. It's much more obvious to anyone using your component
what's going on
there if you create a style sheet where they're likely to
spot it.

It seems like your approach is fine, but maybe you've made a
mistake in your
implementation.

You might want to consider also adding an instance of
HaloBorder to your
component. That brings a lot of functionality with it.

Include xml data file in Flex Library Project

Hi all,
i've got a Flex Library Project in which I include some
assets, as css files and some xml data files too. They are located
in my project root, under /assets/css and /assets/data. Once
compiled, if I use my library in other projects, the css styles
from the css under /assets/css apply, but the xml data files are
not found.Both are checked in the Flex Library Build Path window of
the project's properties.
There's any reason why the xml files are not included? Or
should I reference them in some other way... In my library project
I'm doing: ' theHTTPService.url = "assets/data/data_file.xml" '
thanks in advance,
Marc

Hi Greg, thanks for answering.
Yes, that's what I'd like to know also... I mark it to be
added to the library, but how can I be sure if it's in the final
.swc? Are they browseable somehow?
thanks,
Marc

Flex Library Project(SWC) with css and image assets

HI,
I want to create a flex library project with images and css. I shall use that swc with other flex applications. I wand to use those css and images from the swc. Is it possible? Can you please explain in detail.
Thanks
Nirmal

Right... but how do I reference that CSS outside of the
Libray Project?
All I want my library project to be is a CSS and images
Then I want to include that library project in my main
project, and have the main project call the CSS file inside the
library project

Error in application: custom component Localization in flex library project

Hi!
I created custom component in flex library project and I created resource bundle for it. Now it all compiles, but when I add the component to other project I get an error: Unable to resolve resource bundle "Guestbook" for locale "en_US".
So can someone help me with this?

Where are your resource bundles located in relation to your Flex project src folder?
You may need to add the path to the bundles using Project - Properties - Flex Build Path and then add the parent folder to the resource bundles.
If this post answers your question or helps, please mark it as such.

What's the difference between action script library project and flex library project

i see a new project named actionscript library project. what's the difference?

In ActionScript Library Project, there is no MXML support and Flex related libraries will not be added by default. Otherwise both are similar.

I can't tell from the description whether these are compile time problems or runtime problems, but you could try checking that your Flex project is marked as a 10.0 or later project, and that when you run the SWF you are running it in a 10.0 or later Player.
In the FlashBuilder, there is a section in the project preferences for "ActionScript (Flex) compile". Make sure that the minimum player is 10.0 or later. If you are using Flex Builder 3, this can be done by turning on the HTML wrapper option, and setting the minimum player there.

Cannot compile Library project in Flash builder 4: Unable to locate specified base class

I am migrating from Flex builder 3 to Flash builder 4, during that process I found that Flash builder could'nt compile Flex Library projects which contains components in the form of mxml files. Compiler throws "Unable to locate specified base class".
I have narrowed it down to by creating a flex library project named test library, below its screenshot with its package structure
ControlA is based on componentA
when i compile this project, mxml compiler throws this error
Unable to locate specified base class 'components.componentA' for component class 'ControlA'.
I cannot upload project code because file uploads are disabled on this forum so I am going to paste the code for both componentA and controlA
componentA
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:local="*" width="400" height="300">
</mx:Canvas>
ControlA
<?xml version="1.0" encoding="utf-8"?>
<components:componentA xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:components="components.*" width="400" height="300">
</components:componentA>
To further test it, I have made another library project with same package structure using pure AS3, and it compiled without errors

It might be this happens and other errors if you forget to Run Flash Builder 4.5 Buritto and startup the other version FB4.
It uses the same project listings and that can be confusing since you're not expecting the old version to be aware of new Buritto (MobileApplications) projects you added (thinking) only to the BETA version installed elseware no doubt.
Well it might not be your problem but worthy of noting for other's I'm sure.
Otherwise you've double checked you're using SDK 4.5 Hero with it too! right?

Sharing code between Flex and AIR versions using library project

Hello everyone,
I'm developing an application that has both Flex and AIR versions. In order to share code between these apps, I created a library project and added all my code there. Now I've set the library project as a dependency for both Flex and AIR projects. Since there are some components that use the DataService object, I've added fds.swc and fds_rb.swc and fiber_rb.swc modules to the libs directory of the library project. No compile errors. Now, if I try to run my Flex application, I'm getting this error:
Variable mx.data::LocalStoreFactory is not defined.
I know that this error comes up when playerfds.swc is not present in the path. But that is not the case here. I have added playerfds.swc, fds.swc and related lib files to the build path.
If I go back and add the playerfds.swc file to the original library project, the error no longer appears. This is not a proper solution for me, since I need to share this project with AIR version also, and I cannot have both playerfds.swc and airfds.swc in the same project.. Has anyone faced an issue like this before?? What am I doing wrong??

Flex mobile project as a library for Objective-c project?

We have a objective-c app for ios already,
now we have to add a rtmp based feature(I write that with a flex mobile project).
is there any way to compile the flex mobile project as a objective-c library ,so that the objective-c developer can make that work on ios device?
Please help me ,Thanks!

Usually, people include the objective-c libraries in their AIR applications, using native extensions. However, if you just want rtmp streaming in your native iOS app using flash and not the UI, you may want to use the AV Foundation framework, instead of a flex mobile project.
You may find some useful information and links in this article to achieve it: http://www.adobe.com/devnet/adobe-media-server/articles/streaming-video-ios.html

Create library (swc) in Flash Builder 4 / Flex Project (not in a Library Project)

I want to create a swc file to use it in an other project. I can't use the Flash 4 Library Project to do this, because in a Library Project I
haven't the possibility to use data/services, which I need for my library. After click on "data / services" I get the message "This view is only for Flex-Projects available".
Has anyone a solution for my problem?
Thanks for your help.

Connect to PHP in FB4 is used when you have a PHP Class and you want to use that in FB, for example Employee.php and it has a Employee class and various methods in that like create, update, get, delete.
However, if you have exposed your functionality in PHP as a HTTP URL (i.e. it is not a class), then you should be using HTTPService from the data menu.
So if your file is login.php and is accessible as a URL, then using the HTTPService and enter the URL.
Does this help?

Status Update - don't know if this is a bug, design flaw, install problem or my misunderstanding.
I got it to work by first changing my Flex library to 4.5.0 - still didn't work with current
app and update mxml files using "2.6" for their namespace versions. But I did at least
get the popup error number 16815 - indicating an error in the update version namespace.
By leaving my application namespace version at "2.6" and changing the update version to "2.5" ... bingo!
I got my new update installed autiomatically.
Is this how it's supposed to work - or are my runtimes mixed up?
Will this work the same using the Flex 4.5.1 SDK? I'll find out shortly
Hope this helps others.

Bug with swc folders and library projects?

Hi guys, hope someone can help here. We are just in the
process of starting a fairly large flex project and we were trying
to work out a solution so that I as a designer can view and edit
custom components with visual styles applied.
Now I know that you aren't meant to add a style tag into the
component but it was working for me and I could at least preview
the styles in 'design mode'.
The problem arises though when you have a large project with
shared assets across projects. I had 3 projects set up in my
workspace:
Project 1: Library project with css files, swc and graphics
Project 2: Library project with components for Project 3
Application
Project 3: Application project
What I did was to add a external source folder to Project 2
& 3 both of which was Project 1. So far so good, the css loaded
into my application from Project 1 and I could view my styles in my
custom componants in Project 2
But, I needed to add swc files for custom buttons etc in my
application. So, I thought I would just add an swc folder source to
my build path in both my Project 2 & 3 which referenced an swc
folder in Project 1. Well, it did work and I could view everything
fine but (and here is the main problem) this corrupts the
workspace. Once Flex has closed and tries to reopen my workspace it
hangs, same if I change workspace in Flex from another workspace to
this one.
Can anyone help? Is this a flex bug?
TIA
Steve
