Hi,

You need to use Text.setMessage().
Take a look at this example snippet -- http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/org. eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet309 .java

It is used typically used with SWT.SEARCH, but Text.setMessage() works for all Text widgets with SWT.SINGLE style.

i made a search text widget like this:


package br.com.germantech.widgets;

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.ModifyEvent;
import org.eclipse.swt.events.ModifyListener;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Text;

public abstract class SearchText extends Text implements ModifyListener{

	public SearchText(Composite parent) {
		super(parent, SWT.SEARCH | SWT.ICON_SEARCH | SWT.ICON_CANCEL);
		setMessage("Buscar...");
		addModifyListener(this);
	}

	@Override
	public void modifyText(ModifyEvent e) {
		doModify();
	}

	@Override
	protected void checkSubclass() {
		//hacker!
	}
	
	@Override
	protected void checkWidget() {
		//hacker!
	}
	
	public abstract void doModify();
	
}

You should not subclass SWT-Widgets, don't blame anybody if your code
gets broken one day.
