Dabo 0.8.3 Released

We've gotten good feedback from a number of you - it feels like the number of people trying out Dabo is growing. From now on we'll try to keep to a 5-week point release cycle. But once you download and install a point release, you can always use the new Web Update feature to stay updated. The changes in 0.8.3 can be seen in the change log . Enjoy!

Dabo Runtime Engine For Windows 0.7.1 Released

I've just posted an update to the Runtime Engine that fixes some pathing issues that could arise in a few situations - thanks to Joe Brown for helping me work this out. Otherwise the contents are the same as the 0.7 release.

As usual, you can grab it from the Download Page, or via FTP at ftp://dabodev.com/dabo/win.

Dabo Runtime Engine For Windows 0.7 Released

The Dabo Runtime Engine for Windows is a self-contained environment that allows you to run Dabo on Windows without having to first install all of the requirements. It comes with its own version of Python 2.4.4, wxPython 2.6.3.3, and all of the other modules used in Dabo.

The Dabo Runtime Engine is designed for people who are curious about Dabo, but who don't want the bother of installing all the required modules just to see what Dabo can do. It doesn't change any Windows Registry settings, so it will not affect any existing applications on your machine.

This version installs several shortcuts that allow you to simple double-click an icon to run the desired file. Such shortcuts include the AppWizard, Class Designer and Report Designer, as well as several of the demo applications, including the new DaboDemo application, which allows you to see the demo and the code behind it. You can then modify that code to see how your changes affect the output.

The Dabo Runtime Engine comes in two versions: the regular version that just runs the applications, and the Console version that display a command line window containing the application output and debuggng information. They are otherwise identical.

You can download either version, along with all other things Dabo, from: the Dabo Download Page.

Dabo IDE 0.7 Released

We are pleased to announce the release of DaboIDE 0.7. This will eventually be a true Integrated Development Environment, but currently contains a few key tools that aren't yet integrated. Nonetheless, you can visually design your GUI forms and controls, including adding code to methods, assigning property values, and laying out the form elements using the Class Designer. You can design custom reports using the Report Designer. You can build a full-featured application for very easily using the App Wizard.

We'd also like to announce the new 0.7.1 bugfix release of Dabo and DaboDemo. Get all this from the download page.

Dabo Demo 0.7 Released

This version introduces a new demo application written in Dabo that demonstrates various Dabo UI classes. You can see the objects in action, and the view/modify the code that instantiated the objects. This is based on the excellent demo application framework in wxPython, but rewritten in Dabo code. Oh, and minesweeper is faster. :)

Finally! Dabo 0.7!

It's been a busy year for Paul and Ed, but somehow they've managed, with the help of a growing number of users and contributors, to keep the ball rolling and end up with the next incremental release. There have been lots of enhancements and bugfixes (see the ChangeLog), and we are proud of what we've created. You can get the latest release from the download page. Enjoy!

Warning: Current Dabo Not Compatible With wxPython 2.7

We weren't worried about wxPython 2.7 introducing properties, because we knew it would be a while until wxPython 2.8 (the stable release that would go in all the distributions and application developers would use) came into the wild. However, the good folks over at wxWidgets have decided to turbo charge the effort to get wx2.8 out the door so it can be included in the next release of Apple's OS X. The upshot: wxWidgets 2.7 only just appeared on the scene, yet 2.8 is just around the corner, and current Dabo does not work with it, because of the way property definitions work in Python mix-in classes. Basically, some of wxPython's properties are trumping Dabo's, even though Dabo should be the subclass and thus trump everything.

No worries, though. We know how to proceed, but have decided to wait until after the first release of Dabo-0.7. Once we have the fix in 0.8, we'll backport it to the Dabo-0.7 stable version. So, just be patient for now and keep using wxPython 2.6.x with Dabo.

New Stable Release (0.6.6s)

We've uploaded a new stable release, the first since April. Get it from the usual download page. However, stay tuned: hopefully next week we'll be rolling out Dabo-0.7 as the new stable release, and starting development on Dabo-0.8. Ed's been doing most of the work on this, but Paul's been benefitting from the ever-increasing power of the Dabo system in developing several client applications. Thanks as always to everyone asking questions and contributing to the Dabo vision.

Installing Dabo Requirements on WinXP

I just installed a fresh copy of WinXP on a new VM, and wanted to set it up for Dabo development. So I went through the required steps to get all the packages installed, and documented all the necessary URLs. Wow, things have improved on the installation front in the 2 years since I last set up a Windows machine! Every package has a binary installer, making setting up pretty painless. It's documented on this Wiki Page.

Screencast: Populating a Grid Using Business Objects

In response to a question posted on the Dabo Forum on OpenTech, I've put together a screencast that shows how to create a grid using the Class Designer, and then populate it using business objects to get the data. It's about 10.5 minutes long, and the file size is about 10MB, so please be patient if it takes a while to download.

Dabo Runtime Engine For Windows 0.6.4 Released

This is a minor update to the Runtime Engine. Besides containing the latest version of the Dabo libraries, it also fixes some problems with ReportLab that was preventing the ReportDesigner from running. Just run the Uninstall for the old version, and install this, and you should be good to go.

Dabo-0.6.4 and DaboIDE-0.5.5 Released

The AppWizard's table selection page isn't so hokey anymore, allowing one click to toggle the checkbox values. Fixed some unicode problems in dEditor and in saving data back to a database. Fixed a fast cpu problem in the Class Designer. We'd like to thank everyone that is contributing to Dabo by asking questions, submitting issues to the tracker, or just engaging us in discussion.

Dabo-0.6.2 and DaboIDE-0.5.2 Released

We've begun a stable/dev branch strategy for Dabo; currently, the stable branch is 0.6.x and the dev branch is 0.7a. When we find bugs, we'll backport to the stable branch after fixing the dev branch, and then roll out a new point release when we feel it is appropriate. Anyway, the new releases are available as always from the download page.

Dabo 0.6 Released

Grab the latest from the Download Page. Dabo is really shaping up, and it has been a while since the last release, 0.5.1 back in January. There are too many things to list here, but you can always check the ChangeLog file in the root of the Dabo distribution to see what has changed. Also, Ed has summarized the changes here.

In addition to what we've improved in Dabo, we can't forget to mention the Dabo Class Designer, and Dabo Report Designer. Both of these visual design tools are really coming together, and can be found in the DaboIDE repository, which got bumped from version 0.4 to 0.5 today as well. Coming soon will be a graphical menu designer, and coming down the pipe will be an integration of these design tools into an Integrated Development Environment.

RSS Feeds for Source Code Updates.

There is a new service, courtesy of http://www.repocaster.com/, that generates RSS feeds from Subversion repositories. I've registered 3 of the Dabo repositories: the main framework, the IDE code, and the Demo code. The RSS URLs are:

Framework: http://www.repocaster.com/main/get_feed/17

IDE: http://www.repocaster.com/main/get_feed/18

Demo: http://www.repocaster.com/main/get_feed/19

The service isn't completed yet, but I like the idea. If you have an RSS reader, you can add these links and keep up with all the latest changes in Dabo!

Saved Classes and Inheritance in the UI

The Dabo Designer now supports component classes that can be used in multiple forms, with full inheritance maintained. This allows you to not only re-use some useful components, but to have updates to those components automatically appear in the designs that use them.

Let's say you created a 'mover' control: one that moves items between two lists. This can be handy in lots of forms, so you save it as a class. Later on you need to create another form that needs a mover, so you add an instance of your mover class to this new design surface. It will simply work as expected. But now suppose that a few weeks later, after you've used this class in dozens of forms, you discover a bug in your mover code. No problem: just fix the bug in your class, and all the forms that use your mover are also fixed!

Screencast: Dabo Report Designer Overview

I've just posted a new screencast that goes through the basics of designing reports. It takes a quick report as generated by a datanav application, and modifies it to provide grouping and subtotaling. Along the way, the viewer should get a good feeling about the capabilities of the report designer as it stands now.

Running time is 23 minutes.

Screencast: Dabo Report Designer Overview, Part Two

I've continued where I left off at the end of my last screencast, and posted part two. This one is only 10 minutes long and has better audio compression, so it should be a lighter download. And, your feedback has resulted in some better features in the Report Designer.

Suggestions for PyCon Talk

As most of you know, I'll be doing a session at this month's PyCon entitled 'The State of Dabo'. My goal is to both educate people about what Dabo can do, as well as impress them with its power. What I'd like to know is what was it about Dabo that first made you consider taking a good look at it; what first made you think "Wow, this could really be useful!". I only have a 30-minute session, which yields about 20 minutes to show stuff, so I obviously can't show everything. Your suggestions will help me focus on what might impress the folks at the session who have never seen Dabo before.

Dabo Runtime for Windows

The DaboRuntime for Windows has been updated to version 0.3. The runtime comes with a full copy of the Dabo framework, as well as the Demo and IDE files, and allows you to run any of these on a Windows machines without having to install Python, wxPython, the database modules, etc. The framework code is no longer built into the runtime, so you can update the framework as we continue to improve it.

Runtime Installer for Linux?

I haven't updated this page in a while, and didn't want anyone to think that we haven't been working hard on Dabo. Currently the big project is figuring out just how to create a completely self-contained runtime distribution on Linux. It's easy if everyone is using Fedora, since that's what we're running on our development machines, but much tougher if we want to support older machines. I'm making progress, so perhaps in the next week or so I'll have some good news. Keep your fingers crossed!

Visual Designer Update

Work continues on the Visual Designer; the property sheet is working well, and the visual layout of controls using sizers is also coming along nicely. We're also able to save the design to an editable XML format, although this is still open to modification. Next up is to create a floating palette to replace the clunky context menu for adding controls.

Dabo Runtime Engine

An updated Dabo Runtime Engine for Windows has been released. The Runtime Engine allows those of you who don't want to install all of the pre-requisites for Dabo to try it out. It comes as a simple Windows installer program, allowing for easy install/uninstall. This version contains Python 2.4.1 and wxPython 2.6.0, as well as an updatable installation of the Dabo Framework. It also includes support for both MySQL and Firebird databases. You can grab it from our Download Page.
