Time-delaying Cairngorm Commands Execution

Posted by Harry Vikatos | July 8, 2008 | Comment

In cases where data are edited in a Flex client and subsequently have to be saved on a server, one has to manage the frequency of those server calls.

One way of doing this, is adding an extra step, for the user to save the changes made. So image you have an editable data grid, presenting some objects you want to persist on your server. User edits data but then has to press the ‘Save’ button for the changes to be saved. This way you can aggregate all your changes into one server call, instead of making a call for […] Continue Reading…

Passpack DESKTOP With Adobe AIR

Posted by Sravan | July 8, 2008 | 2 Comments

Adobe AIR is slowly becoming a choice even for “serious” applications. Passpack, the online password manager, has recently launched two offline versions — Passpack DESKTOP and Passpack Offline. I have only tried to use the former because it is built with AIR. The other version is essentially the same wrt features.

There are two things that I don’t like about PassPack DESKTOP: the CAPS being more in number than small letters in its name, and the absence of offline help pages. There are two things that I like about the software: its perception of the strength of a password, and […] Continue Reading…

Adobe Suppressing Little Helper Like Apple Did

Posted by Charles | July 7, 2008 | 6 Comments

I’m surprised, puzzled and concerned by Adobe’s act to go after its freelancing technology evangelist by hinting trademark infringement. This happened to an Adobe AIR promoter FreshAIRapps.com, an Adobe AIR application showcase blog by James Whittaker. Apparently, Adobe is not happy about Whittaker’s use of the name “AIR” on hist domain name. According to Adobe:
Adobe® AIR™” is a trademark of Adobe that may not be used by others except under a written license from Adobe. You may not incorporate the Adobe AIR trademark, or any other Adobe trademark, in whole or in part, in the title of your Developer […] Continue Reading…

Flash on 64-bit OSs

Posted by Sravan | July 7, 2008 | 5 Comments

Long ago, people belonging to the Linux community filed a petition to Macromedia, Inc. through PetitionOnline requesting them to release 64 bit Linux Flash and Shockwave players.

In a technote affecting Flash Player 9, Adobe addressed the issue a few months back: Adobe is working on Flash Player support for 64-bit platforms as part of our ongoing commitment to the cross-platform compatibility of Flash Player. We have not yet announced timing or release dates.

Tinic Uro, an Adobe engineer working on Flash Player, once mentioned that “it is not a question of ‘recompiling’ the source code, there is lots of generic […] Continue Reading…

One Year of Flex Camps

Posted by Sravan | July 4, 2008 | Comment

I wish all Americans a Happy Independence Day. Let us hope that the economy woes will soon vanish.

Last July, the Adobe Flex people conducted their first Flex Camp in San Francisco. Ever since there have been several camps held even outside USA: Romania, Italy, Canada, Singapore, Portugal, Poland.

Every Flex Camp is filled with talks, presentations, and products demos. These camps are hosted by Adobe and attended by experts of the Flex community — inside and outside Adobe — and offer everybody a fun-filled chance to learn, network, and gain exposure. Often, there are also hands on events conducted to […] Continue Reading…

b.Tween Bridges Gap Between Adobe and Apple

Posted by Sravan | July 3, 2008 | Comment

Adobe Flash Player is not yet on Apple iPhone. But Flash Lite apps can now be ported to iPhone or iPod Touch.

Thomas Joos from Boulevart and Emanuele Cipolloni from Barefootsoft have successfully ported a Flash Lite project, the “Rock Werchter Mobile Guide”, to the iPhone taking advantage of all the oppurtunities the iphone UI has to offer.

Below is the cool video demo of the final result.

They used b.Tween, which in turn uses eyeGT, for porting the app. eyeGT, or Enhance Your Experience Graphical Toolkit, is a highly efficient graphic renderer, capable of handling vector graphics and bitmaps. b.Tween is […] Continue Reading…

Enhanced search string ComboBox

Posted by Harry Vikatos | July 3, 2008 | 5 Comments

The standard behaviour of the Flex framework combobox, is to adjust its selected option as the user types in characters. However values are looked up only by the first character, i.e. user types in ‘a’ and the first option starting with ‘a’ is selected. He then types ‘b’ and the first option starting with ‘b’ is selected.

Now this may be good enough for short lists of options, but is probably insufficient for longer lists and for intensive data entry, where forcing the user to switch from the keyboard to the mouse makes the process inefficient.

Ideally one would like the combo box jumping its selection […] Continue Reading…

Mozilla Prism Apps aren’t RIAs

Posted by Sravan | July 2, 2008 | 2 Comments

Apart from Adobe, Microsoft and Sun, even Mozilla took notice of the surge in RIAs. It started a project called WebRunner long ago, with a goal “to identify and facilitate the development of enhancements that bring the advantages of desktop apps to the web platform,” and later renamed it as Prism towards the end of last year.

‘Prism’ is a better name that explains the project’s intentions. The below picture will show you what I mean.

Using Prism, you can create your own web apps and add them to your desktop. They will function as stand-alone applications. With Firefox 3 still […] Continue Reading…

The illusive itemRenderer

Posted by Harry Vikatos | July 2, 2008 | 3 Comments

The item renderer is a powerful concept in Flex, that enables custom implementations of data presentation and input within controls like Lists, DataGrids and Charts. In our last post, we saw how a custom item renderer can be used within a bubble chart to enable interactivity. We showcased that using a chart with one data point. That was intentional as there was a bug that starts showing once we add multiple data points.

See the below flex app, demonstrating buggy behaviour:

As the user drags one of the bubbles, the other one occasionally jumps close to […] Continue Reading…
