A First look at JavaFX Scene Builder Tool

It was just announced in JavaOne Japan that the JavaFX SceneBuilder Tool Beta is available for Download. Immediately I downloaded the tool and made a few tests and it's really a great tool. You should also try since it's available for Linux, Mac and Windows. The tool in entirely in JavaFX and you can preview the changes in a minute. In the following screenshot you can have a look of the appearance of the tool when you open it.
You can create application simply dragging and dropping the controls on left side to the center. Depending the control you selected you will be able to modify its properties on right side pane.
There are lines that help you positioning components and aligning them. It makes easy create well known layouts such as Form Layouts.
A cool and useful feature is the preview. You fan preview your application and there's no delay, the tool makes the preview immediately. Much better than spend time compiling and recompiling source code.
Finally you can export the page to a FXML file and use it in your application. The tool is amazing! It's been neither 1 hour it was released and I finished a simple application with it. Of course I noticed a few small bugs while using the new JavaFX app, but they are very small bugs if you consider that the tool is still in beta phase. Now JavaFX has all the keys to success: Open Source, easy, flexible, good tools, multi-platform, big and crescent community and, soon, multi-device, and me. Yeah, I'm back to have fun with JavaFX after a few months away.

Creating custom Work Item Handler in BPM Suite/jBPM 6

Hi all! In this post I am going to share my experience creating a work item handler for BPM Suite 6.0.3 (which is very similar to jbpm as explained in a previous post ). The Hello World Work Item Handler Let's create a really simple WorkItemHandler just to print "Hello World" in the console. Of course you can implement more feature and make it receive parameters, access database, web services, etc. But in this post we will keep it simple. Really simple. First thing to do is to create a maven project for my WorkItemHandler. Here's the pom.xml of my Maven project: Notice that we are importing jbpm dependency so we can find the java interface that is used to create work item handlers. Now we can start coding. Let's create a class name HelloWorkItemHandler in package org.jugvale.jbpm, here is the simple code: Now we can build our project and go to BPM Suite to configure it so we can use this workitem. Registering the WorkItemHandler UPDATE...

Simplest JavaFX ComboBox autocomplete

Based on this Brazilian community post , I've created a sample Combobox auto complete. What it basically does is: When user type with the combobox selected, it will work on a temporary string to store the typed text; Each key typed leads to the combobox to be showed and updated If backspace is type, we update the filter Each key typed shows the combo box items, when the combobox is hidden, the filter is cleaned and the tooltip is hidden:   The class code and a sample application is below. I also added the source to my personal github , sent me PR to improve it and there are a lot of things to improve, like space and accents support.

Dancing lights with Arduino - The idea

I have been having fun with Arduino these days! In this article I am going to show how did I use an electret mic with Arduino to create a Dancing Lights circuit. Dancing Lights   I used to be an eletronician before starting the IT college. I had my own electronics maintenance office to fix television, radios, etc. In my free time I used to create electronic projects to sell and I made a few "reais" selling a version of Dancing lights, but it was too limited: it simply animated lamps using a relay in the output of a 4017 CMOS IC. The circuit was a decimal counter  controlled by a 555. 4017 decimal counter. Source in the image When I met Arduino a few years ago, I was skeptical because I said: I can do this with IC, why should I use a microcontroller. I thought that Arduino was for kids. But now my pride is gone and I am having a lot of fun with Arduino :-) The implementation of Dancing Lights with Arduino uses an electret mic to capture the sound and light leds...
