GWT + AppEngine : Space Map Explore

I try to create a huge space map using GWT.

Here is my first try :

You can use mouse wheel to zoom in or out, and drag and drop to move.

I have encounter some performance issues but I think I fix it :D

Create a MP3 Player for iPhone and Android Using GWT and Titanium

Titanium is a tool provide by appcelerator.com, which allow you to transform web application into native iPhone or Android App. I try to play around a little and I create a MP3 Player in GWT, which can be export on iPhone or Android.

Here is the code (See how it's simple) :

public class Player extends Composite implements ClickHandler

{

private VerticalPanel _vpanel;

private HorizontalPanel _hPanel;

private TextBox _box;

private Button _play;

private Button _stop;

private Sound _sound;

public Player()

{

this._hPanel = new HorizontalPanel();

this._box = new TextBox();

this._play = new Button();

this._play.addClickHandler(this);

this._play.setHTML("Play !");

this._hPanel.add(this._play);

this._stop = new Button();

this._stop.addClickHandler(this);

this._stop.setHTML("Stop !");

this._hPanel.add(this._stop);

this._vpanel = new VerticalPanel();

this._vpanel.add(this._box);

this._vpanel.add(this._hPanel);

initWidget(this._vpanel);

this._sound = null;

}

public void onClick(ClickEvent event)

{

if (event.getSource() == this._play)

{

this._sound = new Sound(this._box.getValue());

this._sound.play();

}

if (event.getSource() == this._stop)

{

if (this._sound != null)

{

this._sound.pause();

}

}

}

}
