package ExampleViewer.form;

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

import ExampleViewer.data.IExampleContentProvider;


public class TextField extends Field {

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

	/* (non-Javadoc)

	 */
	public  void readFromContent(IExampleContentProvider content) {
		String newText = (String )content.getElement(getId());
		if (newText != null)
			((Text )_control).setText(newText);
	}

	/* (non-Javadoc)
	 * @see com.ibm.eworkplaces.pim.ui.docedit.form.IField#setData(java.lang.Object)
	 */
	public void writeToContent(IExampleContentProvider content) {
		String	newText = ((Text )_control).getText(); 						
		content.setElement(getId(), newText);
