New Nokia S60 Touch Enabled Emulator

Few days ago Nokia has released new version of Symbian S60 emulator. It has many improvements but what is really important touch screen support is one of it. We should see first device from Nokia based on this OS soon (Nokia 5800) but before it is aviliable on the market everyone can try it by installing S60 Platform SDKs for Symbian OS. This platform has implementation of Java ME and it was really interesting to see how Nokia deals with touch enabled MIDP components. I have to say I'm positively surprised. All MIDP components are "touch-enabled" and what is very important easy to use. Also I really like Look and Feel of these components. I've made a few test and it looks like all components are big enough to operate them using fingers so no need for stylus :). First screenshoot shows MIDP UI in Landscape mode. All changeable/editable elements of this UI can be operate using touch screen.

Second screenshot shows same UI in "normal" mode.

Application based on Canvas in landscape mode.

One annoying thing about this platforms is strange keypad in applications which use Canvas. I understand that most of the current Java ME apps based on canvas does not support touch screen but on the other hand it is very ugly and breaks composition of the UI. I hope it is possible to switch this keypad off somehow if support for touch screen is available in particular application. If you'd like to try this new cool platform with Netbeans Mobility all you have to do is to add it to the list of Java Platforms in Netbeans using "Tools > Java Platforms > Java ME MIDP" then point folder with installed S60 Platform SDK and you ready to go.

Overview of the Visual Designer Components

In Netbeans Mobility 6 we have introduced new components like File Browser, SMS Composer or new SVG Components. They all well documented in the tutorials and documentation but I've noticed that MIDP related components don't have any overview or description in Mobility documentation (which could be a problem for less experienced Java ME developers). Thats why I've created simply overview of the Mobility Visual Designer components which is available here:

Mobility Components Overview

We also have few old (NetBeans Mobility 5.x) tutorials which are still valid for version 6. If you try to run examples from this tutorials please change Java ME platform from WTK 2.2 to WTK 2.5.2 and also screen shots show old version of Mobility but most important thing which is components API is unchanged.
