[Swixat-devel] new version of MemoryStatus

[JP <pet...@ro...>]

I like the idea of the MemoryStatus widget, but don't care for its
implementation. Here's a new version that extends JProgressBar.
Obviously, it's better at conforming to whatever your look-and-feel is,
and the code is cleaner and simpler. Let me know if you guys like it.
If so, I'll replace the current MemoryStatus with this one.

-----------

public class MemoryBar extends JProgressBar implements ActionListener {

	private Timer timer;

	public MemoryBar() {
		super();
		setStringPainted(true);
	}

	/**
	 * called by timer
	 */
	public void actionPerformed(ActionEvent evt) {
		Runtime runtime = Runtime.getRuntime();
		int freeMemory = (int) (runtime.freeMemory() / 1024L / 1024);
		int totalMemory = (int) (runtime.totalMemory() / 1024L / 1024);
		int usedMemory = totalMemory - freeMemory;
		setMaximum(totalMemory);
		setValue(usedMemory);
		setString(usedMemory + "M of " + totalMemory + "M");
	}

	/**
	 * Adds a feature to the Notify attribute of the MemoryStatus object
	 */
	public void addNotify() {
		super.addNotify();
		timer = new Timer(2000, this);
		timer.start();
	}

	public void removeNotify() {
		timer.stop();
		super.removeNotify();
	}

}
