What I found interesting is that it looks like this native GUI could also be used under JavaFX's mobile profile and, most importantly, that the authors created a <a href="http://javafx.com/samples/ProjectManager/src/DataHandler.fx.html">mock data access layer</a> (accessing only in-memory collections) leaving room for easily plugging in my favorite (JavaFX compatible) object persistence engine: <a href="http://developer.db4o.com/">db4o</a> =)<br /><br />With the help of Dama (my wife) we changed the <a href="http://javafx.com/samples/ProjectManager/src/DataHandler.fx.html">original data handler</a> to include db4o and wanted to share this sample with you. We used db4o v7.9 which is accessed straight from JavaFX (if you want to learn more about the limitations of db4o under JavaFX I suggest you read Patrick's blog post <a href="http://developer.db4o.com/blogs/community/archive/2009/03/20/db4o-with-javafx.aspx">'db4o with JavaFX'</a>).<br /><br />If you want to use db4o in your JavaFX application you're adviced to reuse <span style="FONT-WEIGHT: bold">Db4oFX.fx</span> (available in the download bundle below) to save yourself some time (it's a sort of JavaFX API to db4o) which in turn uses <span style="FONT-STYLE: italic">Reflex.java</span> (for some reflection magic). The data handler for this application (which benefits from these utility classes) is called <span style="FONT-STYLE: italic">DataHandler.fx</span>.<br /><br />Thanks to Praveen Mohan &amp; Elancheran for sharing the original sample.<br /><br /><a href="http://developer.db4o.com/ProjectSpaces/view.aspx/JavaFXDemo/ProjectManager.Zip">Download Sample</a><br /></span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8355370-6831041477251903987?l=planetgerman.blogspot.com' alt='' /></div><img src="http://feeds.feedburner.com/~r/PlanetGerman/~4/Akbd80TLIAU" height="1" width="1"/>German Viscusohttp://www.blogger.com/profile/05542920325440015442noreply@blogger.com1http://planetgerman.blogspot.com/2009/07/project-management-system-using-javafx.htmltag:blogger.com,1999:blog-8355370.post-88113535478801443962009-04-07T21:55:00.003-03:002009-04-07T22:06:59.603-03:002009-04-07T22:06:59.603-03:00I just run into a second nasty experience with Twitter.
