Creating Rich Clients with Apache Pivot

Sun, 19 May 2013 00:00:00 +0200

Apache Pivot is a modern framework to create rich clients as desktop applications or to run in a web browser.

It offers nice GUI elements, supports XML/WTKX templates, data bindings, JVM scripting languages and much more.

In the following short examples I’m going to create a desktop application to open a file browser, select a file and output the selected file’s name, first using a programmatic approach to create the user interface, and afterwards using XML/WTKX templates.

Today we’re going to take a look at Google’s App Inventor feature that offers programming-novices a nice possibility to enter the fabulous world of Android App programming without deeper knowledge of the API or complex SDK installations.

So lets build some stuff ..

Prerequisites

Java 6 JDK
App Inventors Extras Software
A Google App Inventor Beta Account – request one here

What we are going to build

We are building a simple GUI with a Textbox and a button
A click on the button starts an event that queries the acceleration sensor for coordinates
If the sensor is active and enabled then the coordinates are displayed in the text box
