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：
