如何在Swing中获取JWindow的父容器?

问题描述

我有一个JFrame，并在初始化时从该帧调用JDialog.在对话框中有一个JButton，单击按钮时将打开一个新的JWindow.

I have one JFrame and calling a JDialog from that frame while initializing. In the dialog have a JButton, when clicking on the button a new JWindow opens.

我可以在主框架中固定窗口的位置吗?如何从JWindow扩展类访问父容器(扩展为JFrame)?

Can I fix the position of window in the main frame? How to access the parent container (JFrame extended) from JWindow extended class?

推荐答案

使用 SwingUtilities.getWindowAncestor ，如果在JWindow类中，则将其引用为this，如果没有，则将对象放在里面:

Use SwingUtilities.getWindowAncestor, if inside the JWindow class, refer it as this, if no, simply put object inside:

JFrame topFrame = (JFrame) SwingUtilities.getWindowAncestor(this);

JFrame topFrame = (JFrame) SwingUtilities.getWindowAncestor(myJWindow);
