FDT vs Flex Builder features compare

Panel — Thu, 23 Apr 2009 10:09:56 +0000

I was working with Flex Builder for a long time and recently decided to try FDT (Development Tool for Flash). I’ll review features new for me and features missing from Flex perspective. This comparison will focus the differences and only for pure Actionscipt 3 coding (no MXML).

Feature	Flex Builder 3	FDT 3
Debugging
Displaying xml structure in Debugger panel
Ability to highlight changed variable value		No
Displaying private class members in Debugger panel	No	Yes
Coding & Refactoring
Code templates	No	Yes
Advanced code formatter	No	Yes
Ability to compile project with errors	No	Yes
Hinting language key words	No	Yes
Ability to add new method, by typing it’s name on object instance	No	Yes
Change package name when moving classes between packages	No	Yes
Hinting package path (crtl+space to fill full package path)	Yes	No
Unused import management	Remove unused imports	High light as warning
Automatic imports, comments flooding	No	Yes
Validate embed resources (path, internal symbols)	When project is saved (better)	When project is compiled
Advanced syntax checking	No	Yes
Syntax checking	on save	on t he fly
Replace Phrase in whole project	No	Yes
Ability to run application in standalone debug player	Yes	Yes
Create constructor when creating new class	Always	Only if class extends another class
Displaying package structure
General
Profiler	Yes	No
Stability	Unstable – I can’t even say how many times I got ‘internal build error’ and have to restart Flex.	Very stable
Speed	FDT is a little bit slower (ex. It takes a little bit longer to display list of variables in debugger panel, etc.)

As we can see above each application have it’s own cons and pros. Both of them have nice unique features. Definitely the best choice would be just to mix of both. At the moment FDT is my choose, mainly because of templates support and stability although I regret it cannot display xml data in debugger view the way Flex does.

Flex builder running applications in Projector (Standalone FlashPlayer)

Panel — Wed, 18 Feb 2009 16:52:48 +0000

Personally I don’t like to run/debug/profile applications in browser. Sometimes few tabs are opened in browser, sometimes browser may even crash. Projector or Standalone FlashPlayer is desktop application allowing you to run swf files. There is a way to use projector to run/debug/profile your Flex projects (projects created in flex – flex project or actionscript project, etc..).

I have tested this on windows but on mac it should be the same.

First of all you have to download projector from Adobe webside. Sine it will be also used to debug applications you should download debug version – Projector content debugger (EXE)

http://www.adobe.com/support/flashplayer/downloads.html

Then you have to download projector exe file somewhere to your hdd. After you save projector exe you’ll have to ‘register’ it into system registry by simply running it (it will register path to default application witch will be used to open swf files). Now each time you’ll run swf file it will be launched in this specified projector, so make sure you won’t move this projector file. You can use this ‘relation’ ex for changing projector versions witch will be used to run/debug/profile your project.

Now go to Flex and create new project. Go to Run menu -> Run -> other

Double click on Flex Application to create new run configuration. Select newly created configuration and Uncheck use defaults. Now just change .html extension to .swf in all 3 paths (Debug, Profile, Run) and click Apply.

Now each time you’ll run/debug/profile you project it will be launched in projector. The downside is you’ll have to change those settings separate for each project.

There is a Bug (on Windows Vista) – sometimes after clicking on configuration you won’t see right window content. There isn’t 100% working solution, but there are few things you can try.

Try to change width by dragging ‘center separator’ (try to open whole run configuration window few times and drag).

Try to run Flex in Compatibility mode right click on FlexBuilder.exe (default path is C:\Program Files\Adobe\Flex Builder 3) , select properties, go to compatibility tab, select run program in compatibility mode, and choose Windows XP
Try to disable visual themes for Flex (compatibility tab as above)

Watch Full HD movies on you laptop

Yes – it’s true you can watch Full HD movies on relatively week mobile pc. You just have to download Windows 7 Beta 1 (expires on August 1, 2009).

Windows 7 Beta Customer Preview Program

My configurration is Intel Core 2 Duo T5250 – 1.5GHz with Intel 965 Graphic Card (It also works on Intel Core 2 U7500 1,06 GHz). Movies work fluently without any problems.

I have just installed Vista Codec Package 5.09

Debug Flash/SWF connections

Panel — Wed, 03 Dec 2008 09:05:26 +0000

Debugging conections is all about to see what http requests where made, what data was sent/recieved…

Webside

Here you have two options:

Local proxy server. Basically you configure your browser to use proxy for default Internet connection and all requests goes thought proxy to Internet. There is nice free proxy server called Fiddler. If you do not want your proxy run all time, you should have possibility to change connection setting quickly (proxy / no proxy). There is FireFox add on called FoxyProxy witch allows you to switch between different proxies. If configured correctly it allow you to disable/enadle proxy by one mouse click on FireFox statusBar.

FireFox addons – my favorite is Firebug. Make sure cache in FireFox is disabled (becouse when file is cached you won’t see any connections).

Desktop

Lately I have discovered that Flash CS3 is using system settings for Internet connection. It means that you if you change system proxy (control panel -> internet settings -> connection -> Lan Settings -> proxy) for your proxy server flash CS3 will use tour proxy and you’ll be able to review all connection made from your application.

Generate Actionscript 3 code with Eclipse Monkey (Flex Builder)

Panel — Sun, 01 Jun 2008 17:45:15 +0000

Writing getters, setters, handler functions and even consts takes time. After working for a while I got feeling that this process can be automated. Lately I have discovered Eclipse plugin called Dash (thanks to eokyere). It contains Eclipse Monkey witch s a dynamic scripting tool. Scripts (written in Javascript) can be used to generate Actionscript code directly inside FlexBuilder. Unfortunately it will work only with Actionscript projects (won’t work with Flex projects).

Watch quick demo

Instalation

Inside FlexBuilder to to Help-> Software Updates-> Find and Install
Search new features to install
Add New Remote Site (enter name and url (http://download.eclipse.org/technology/dash/update)
Click finish to check for updates and install Eclipse Monkey
Restart Flex Builder
You should see Script menu
File -> New -> Other… -> General -> Project
Enter project name ex. Eclipse Monkey Scripts & click Finish
Create script folder inside this project and copy scripts
Now all scripts should be available in Scripts menu – if not select Eclipse Monkey Scripts project and press F5 (or right click on project -> refreash) to refresh it

Scripts

As you have seen on the video I have already created few scripts for Generate Event Handlers, Generate Properties and Generate Consts. I also have two scripts from Konstantin Kovalev blog.

Bug in addChild method

Panel — Sat, 31 May 2008 14:08:56 +0000

Yesterday I have discovered that addChild method of DisplayObject is not working as expected. While adding new child to displayList it ignores override for width/height getters.

It can be very confusing. Imagine you have image gallery witch displays images in row. Now you wanna mask 3 of them to make only 3 of them visible at time and create some scroll. If you are using some advanced layout system (let’s say you wanna center your image gallery) natural step it to override get width/get height properties, so mask size will be returned instead.

Here is Code Sample
