关闭JPanel的父元素

Question

是否可以关闭组件的父元素..可能是来自JPanel的JFrame / JInternalFrame？如果是的话怎么做？

Answer 1

这将对您有所帮助：

SwingUtilities.windowForComponent(panel).dispose();

或

SwingUtilities.windowForComponent(panel).setVisible(false);

Answer 2

this answer的修改版

public class CustomPanel extends JPanel {

  private JFrame parent; //Need to pass this reference somehow, constructor or otherwise

  public void closeJFrame() {
    WindowEvent winEvent = new WindowEvent(parent, WindowEvent.WINDOW_CLOSING);
    Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(winEvent );
  }
}
