Eclipse插件开发：SWT之ListExample

该例子演示了SWT界面下的List(单选列表）构建及监听。

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.List;
import org.eclipse.swt.widgets.Shell;
public class ListExample {

public static void main(String[] args) {

Display display = new Display();

Shell shell = new Shell(display);

shell.setText("List Example");

shell.setBounds(100, 100, 200, 100);

shell.setLayout(new FillLayout());

final List list = new List(shell, SWT.SINGLE);

list.setItems(new String[] { "First", "Second", "Third" });

list.addSelectionListener(new SelectionAdapter() {

public void widgetSelected(SelectionEvent event) {

String[] selected = list.getSelection();

if (selected.length > 0)

System.out.println("Selected: " + selected[0]);

}
		public void widgetDefaultSelected(SelectionEvent event) {
			String[] selected = list.getSelection();
			if (selected.length > 0)
				System.out.println("Default Selected: " + selected[0]);
		}
	});
	shell.open();
	while (!shell.isDisposed()) {
		if (!display.readAndDispatch())
			display.sleep();
	}
	display.dispose();
}

}
