Important features running here are states, setters, constraints, mouse kernel, input text (still a bug there with default width of
the underlying Flash textfield object)
The Webtop team has been hard at work and has just released a preview of the new Laszlo Calendar on gowebtop.com. You can read more on their blog, but it is definitely worth checking out to see what is possible in OpenLaszlo.
I’ve opened a discussion on the project forums about how to improve how we distribute information about the project and updating the project blog. If you read this blog (live or via RSS), your opinion is solicited on how I can make this better for you. Please visit:
If you’re trying to get the most out of OpenLaszlo, consider taking one of our training classes on OpenLaszlo. We’ve just scheduled sessions here in San Mateo for both OpenLaszlo Fundamentals and our Building OpenLaszlo Applications classes. Sessions in Toronto and Hyderabad are also being scheduled.
There is a new utility checked into trunk, which is a command line interface to build SOLO deployment zip archives.
You invoke it via the “lzdeploy” script, which is in
WEB-INF/lps/server/bin/lzdeploy
It take the following arguments, and produces an output file by default in the same directory as the app
resides. So for example if it is invoked on a relative path to an app in directory “test/foo/hello.lzx”
lzdeploy –runtime=dhtml test/foo/hello.lzx
it will produce a zip file, test/foo/hello.lzx.zip. This is basically the same routine that is run by the SOLO deploy ‘wizard’ jsp
script, but can be run from the command line, without needing to use the browser and LPS server.
Options:
-D<name>=<value>
Set the name/var property to value (See Compiler.getProperties).
-D<name>
Short for -Dname=true.
–wrapperonly
Only emit html wrapper page.
–runtime=[swf7|swf8|swf9|dhtml]
Compile to swf7, swf8, swf9, dhtml
–output pathname
The name of the output file to write.
–title titlestring
The title of the application to use in the wrapper.
-v
Write progress information to standard output.
–help
Prints this message.
Work is underway to to extend the compiler to know how to emit a singleton classes for views which declare methods or constraints. This is needed to support the unique feature of the LZX language which allows you to program an instance as if it were a full-fledged class.
There is also a simple debugger area, where you can type arbitrary javascript expressions, which are compiled at the LPS server and executed interactively, in a similar manner to the SWF8 debugger. The port of the full SWF8 debugger is planned.
Work remaining to be done includes porting the LFC data-handler classes, and supporting the media playback APIs in the swf9 LFC kernel.
According to Tony, Developers face many architecture choices when building Web applications. The target client is often a key factor when deciding which development platform to use.
OpenLaszlo can help you clear this hurdle by delivering a runtime that runs on all browsers. OpenLaszlo provides a platform for building rich Internet applications that may mimic desktop application functionality. Here’s a closer look at OpenLaszlo’s features, architecture, language, and development environment.
Interview with David Temkin posted on a new Cinematic Interface weblog. (I’ve kicked off the blog with this interview, but the design team at Laszlo plans to chime in with more insights.)
David talks about the origins of the term and has a good definition of what we mean by the “cinematic user experience:”
An interface where two things are going on: one is that you have objects on the screen that are manipulable and respond to commands with motion; and the second piece is that motion actually tells a story about the role of those objects within the overall application and the role of those objects and those transitions within the task that you are trying to complete. Just as in a movie, a director seeks to cue the viewer from what was going on to what is happening next. In a movie, the camera might move, with a pan, or a zoom… (read more)
OpenLaszlo 4.0.10 is a is the latest version of OpenLaszlo and contains many bug fixes, enhancements, and other changes from previous versions. OpenLaszlo 4.0.10 is the first release of the code base that contains significant changes for DHTML support. In addition, the documentation effort, while not complete yet, has been significantly updated to include new features, such as explicit replication and data API.
If you are using an earlier version, we recommending upgrading to 4.0.10, which is the recommended release for swf development. Support for applications to DHTML remains at “beta” level; it will be fully supported with OL 4.1.
The list of changes is significant. To see the complete list, please refer to the Release Notes
For every release, we rely on the OpenLaszlo community to help ensure the quality of the platform release and to determine its future direction. To propose or participate in discussion of new features, see the wiki. We encourage you to report any problems, and to make suggestions for enhancements, through our JIRA bug tracking system.
OpenLaszlo 4.0.9 is a bug fix release. For a detailed list of the bugs fixed, see the Release Notes. OpenLaszlo 4.0.9 is the recommended release for swf development. You can download it here.
OpenLaszlo 4.0.9 fixes the following bug:
[LPP-5368] - Can’t have query string with queryType=”POST”
