主题:应用程序运行不对?
一应用程序:
/**@author WangJinTao,MengQingChang 2006
*/
package event;
import org.eclipse.swt.widgets.*;
import org.eclipse.swt.*;
import org.eclipse.swt.events.*;
import org.eclipse.jface.dialogs.*;
public class ListenerExample {
public static void main(String[] args) {
final Display display = Display.getDefault();
final Shell shell = new Shell();
shell.setSize(200, 120);
shell.setText("监听器实例");
Button button = new Button(shell, SWT.PUSH);
button.setBounds(35, 25, 120, 25);
button.setText("确定");
button.addSelectionListener(new SelectionListener() {
public void widgetSelected(SelectionEvent e) {
MessageDialog.openInformation(shell, null, "HelloWorld!!");
}
public void widgetDefaultSelected(SelectionEvent e) {
}
});
shell.open();
shell.layout();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
}
}
运行结果应该是:
出现一窗口,点击确定.出现一对话框.
而实际上呢是:
出现一窗口,点击确定按钮,程序结束,窗口也消失(任务栏上不显示),在控制台上出现以下语句:
