Pär Sikö


Pär is a java developer, working primarily with Android but with a long and happy history that includes J2ME, Swing and JavaFX.

He’s been working with Java since it’s inception and tried everything from architecture and large enterprise systems to mobile devices.

As a developer Pär is curious and thorough and knows the importance of pixels and colors. Curious to learn new things, growing as a human being in the process, and happy to teach and inspire others about it. Thorough to ensure that the quality is on par with expectations and, perhaps most importantly, to really understand something makes it so much easier and fun to work with. Pixels and Colors have never been as important as it is today, everything is measured by it’s looks, and Pär’s focus on making beautiful applications is a deliberate strategy that has paid off numerous times.

Pär has been a busy speaker for the last couple of years, presenting on the international stage.

He was awarded with a ‘JavaOne Rock Star’ for his presentation in San Francisco 2011. For Pär, the key success factor in a presentation is mixing good content with a big portion of humour and he wishes that more people would dare to step away from boring bullet lists and do something new and creative when presenting.

Presentation I:

Java FX Introduction

Language: EN

Swing has been a great retainer for years, but with today’s focus on rich user interfaces, many Java applications can benefit from using JavaFX instead. The question is, how do you manage that when you’re stuck with a an old Swing front end? This presentation starts with a typical Swing application and replaces parts of it with a shiny new JavaFX interface. During this transformation event listeners are replaced by JavaFX bindings, hardcoded color constants are replaced by style sheets and instead of the limited HTML support in Swing, the JavaFX WebView component is used to display formatted content. After this presentation the audience will have a thorough understanding of how JavaFX can replace all or parts of a Swing user interface.

Presenation II:

JavaFX Mashups

Language: EN

A mix of content or functionality from two or more Web-based services has become known as a mashup. This presentation takes the mashup concept one step further by mixing Web content and scripts with a JavaFX program, effectively blurring the line between Web and application. This is made possible by the powerful WebView component of JavaFX. The session shows how to display Web content in a JavaFX application and how to set up two-way communications between the Java code and JavaScript code run in WebView. It includes several cool and creative examples based on this technique.
