Swing - How to close a form from inside? How to close the form without affecting the parent form?
提问by Bick
I am creating a form in Swing toolkit.
When I want to close it, I go to the JFrame and set it to visible false.
Since the frame creates a Java class of the form, I can easily do it from outside.
我正在 Swing 工具包中创建一个表单。
当我想关闭它时，我转到 JFrame 并将其设置为可见的 false。
由于框架创建了表单的 Java 类，因此我可以轻松地从外部完成。
When I have a cancel button I usually send a listener inside the form that calls the outer:
当我有一个取消按钮时，我通常会在调用外部的表单内发送一个侦听器：
Jframe.setVisible (false)
Is there a better way ?
有没有更好的办法 ？

The SwingUtilitiesclass provide a method to get the window ancestor of a given component.
You can gat the parent Window and call setVisibleor disposeor perhaps only an event.
本SwingUtilities类提供一个方法来获得一个给定的组件的窗口祖先。您可以打开父窗口并调用setVisible或dispose仅调用一个事件。
Window window = SwingUtilities.getWindowAncestor(this);
window.setVisible( false );
// OR
window.dispose();
// OR
WindowListener[] windowListeners = window.getWindowListeners();
windowListeners[0].windowClosing( null );
