Eclipse插件开发：SWT之MenuExample

该例子演示了SWT界面下的Menu(菜单)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.widgets.Display;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.MenuItem;
import org.eclipse.swt.widgets.Shell;
public class MenuExample {

public static void main(String[] args) {

Display display = new Display();

final Shell shell = new Shell(display);

shell.setText("Menu Example");

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

Menu bar = new Menu(shell, SWT.BAR);

shell.setMenuBar(bar);

MenuItem fileMenu = new MenuItem(bar, SWT.CASCADE);

fileMenu.setText("&File");

Menu subMenu = new Menu(shell, SWT.DROP_DOWN);

fileMenu.setMenu(subMenu);

MenuItem selectItem = new MenuItem(subMenu, SWT.NULL);

selectItem.setText("&Select Me Now\tCtrl+S");

selectItem.setAccelerator(SWT.CTRL + 'S');

selectItem.addSelectionListener(new SelectionAdapter() {

public void widgetSelected(SelectionEvent event) {

System.out.println("I was selected!");

}

});

//MenuItem sep = new MenuItem(subMenu, SWT.SEPARATOR);

MenuItem exitItem = new MenuItem(subMenu, SWT.NULL);

exitItem.setText("&Exit");

exitItem.addSelectionListener(new SelectionAdapter() {

public void widgetSelected(SelectionEvent event) {

shell.dispose();

}

});

shell.open();

while (!shell.isDisposed()) {

if (!display.readAndDispatch())

display.sleep();

}

display.dispose();

}

}
