Eclipse插件开发:SWT之ButtonExample

    该例子演示了SWT界面下的Button构建及监听事件。

    代码如下:


    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.Button;
    import org.eclipse.swt.widgets.Display;
    import org.eclipse.swt.widgets.Shell;
    
    public class ButtonExample {
    	public static void main(String[] args) {
    		Display display = new Display();
    		Shell shell = new Shell(display);
    		shell.setText("Button Example");
    		shell.setBounds(100, 100, 200, 100);
    		shell.setLayout(new FillLayout());
    		final Button button = new Button(shell, SWT.PUSH);
    		button.setText("Click Me Now");
    		button.addSelectionListener(new SelectionAdapter() {
    			public void widgetSelected(SelectionEvent event) {
    				button.setText("I Was Clicked");
    			}
    		});
    		shell.open();
    		while (!shell.isDisposed()) {
    			if (!display.readAndDispatch())
    				display.sleep();
    		}
    		display.dispose();
    	}
    
    }

    运行效果:
