Starting with the new NetBeans Platform CRUD Application Tutorial, I ended up with a slightly more complex application. Here, there's also an OutlineView, which has its own Node, with Children that are added via a LookupListener on the Children object: Note that the viewer and the editor are in 2 separate modules. As a result, whenever an item is selected in the explorer view, it is (1) shown in the text fields, (2) added to the OutlineView, and (3) shown in the Properties...

This tutorial shows you how to integrate a MySQL database into a NetBeans Platform application. We start by exploring a MySQL database, for which we create an entity class. However, note that these instructions are not applicable to MySQL only. Rather, they are relevant to any relational database supported by NetBeans IDE. Next, we wrap the entity class into a module, together with modules for the related JPA JARS. Once the above modules are part of our application, we create...

Today I completed the coding of a CRUD application on top of the NetBeans Platform, using data retrieved/stored via MySQL and EclipseLink: Next week, I will create the 2nd (and final) part of the screencast on this topic. In the first part, the viewer is described (i.e., the tree structure in the left part of the application above), while the second part will focus on all the editing functionality, which includes a 'Refresh' action on the root node. Interestingly, perhaps,...

The original question asked by John on the mailing list was about dragging an item from a palette and dropping it in a BeanTreeView. So, after following the previous two blog entries on this topic (here and here), I reimplemented the scenario to use a Palette instead. Note that a Palette only works if it is created for a TopComponent that is in the "editor" position (read about that in German here), as is the case below: I drag the palette item and then I hold down the Ctrl...

The great Liang Ye, Chinese translator of "Rich Client Programming: Plugging into the NetBeans Platform" sent me the translated book this week. I was very impressed to be able to flip through the book and see texts such as the following: The picture above was taken by Ruth. The book is autographed by Liang himself, dedicated to Jaroslav Tulach, Tim Boudreau, and myself. I showed it to Jaroslav two days ago and he was very impressed too. Next time I see Tim I hope I'll have...

Let's extend the example from yesterday to support a drop of the Node onto a BeanTreeView instead of our TopComponent. In the end, we'll have two TopComponents, like this: When you hold down the Ctrl key and drag a Node from the list of boy names, you can drop it onto a name in the list of girl names, which will cause the boy name to be added to the list of girl names: Do the following: Take the steps outlined in yesterday's blog entry. That's the starting point for the steps...

The question of the day comes from someone only known as John, who wants to drag an item from the Palette into an explorer view, such as the BeanTreeView. Well, I don't have the complete answer yet, but the first steps, which might end up providing the beginning of the end for John. At the end of this blog entry, you'll be able to drag a Node from a BeanTreeView (which could be a Node anywhere, such as in a Palette) into a TopComponent, where the drop results in the change to...

Lest this feat pass by unnoticed, Heiko's 400 page "NetBeans Platform 6: Rich Client Entwicklung mit Java" has been translated into English... in the space of one month. (Update: It has also been published and released!) Traditionally, book translations take a very long time because the initial enthusiasm with which the translators begin falters as the time-space-continuum intersects with it. Putting it more prosaically: "one tends to get bogged down". That, in a nutshell, is...
