SWT/JFace在窗口中打开新的窗口

打开提示/警告窗口:

dButton.addSelectionListener(new SelectionListener() {
			@Override
			public void widgetSelected(SelectionEvent e) {
					MessageDialog.openInformation(getShell(), "提示/警告标题","提示/警告内容");
				}		
			}
			
			@Override
			public void widgetDefaultSelected(SelectionEvent e) {
				// TODO Auto-generated method stub
				
			}
		});

打开新窗口:

button.addSelectionListener(new SelectionAdapter() {
			@Override
			public void widgetSelected(SelectionEvent e) {
				Shell shell1=new Shell();
				shell1.setText("新窗口");
				GridLayout gridLayout=new GridLayout(2, false);
				shell1.setLayout(gridLayout);
			
				Label label2 = new Label(shell1, SWT.NONE);
				label2.setLayoutData(new GridData(SWT.BEGINNING, SWT.CENTER, false, false));
				label2.setText("欢迎观看新窗口");

				Button button=new Button(shell1, SWT.PUSH);
				button.setText("这是一个按钮");
				
				shell1.open();
			}
});

注意SelectionListener()与SelectionAdapter()之间的区别
