利用 java SWT 实现MVC功能

package ExampleViewer.form;

import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Control;

import ExampleViewer.data.IExampleContentProvider;




public class CheckField extends Field {

	/**
	 * @param control
	 * @param id
	 */
	public CheckField(Control control, int id) {
		super(control, id);
	}

	/* (non-Javadoc)

	 */
	public  void readFromContent(IExampleContentProvider content) {
		boolean check = ((Boolean)content.getElement(getId())).booleanValue();
		((Button)_control).setSelection(check);
	}

	/* (non-Javadoc)
