如何关闭Jframe而不关闭其他框架Netbeans

Question

So when I click on X button the whole program closes but i only want to close the frame which I want to close i am using Net beans. I can't figure it out Google says to add closing event but as i see the X button is already there. What to do?

Answer 1

I am creating a program for inventory management where i have 3-4 frames

An application should only have a single JFrame.

If you need child windows then use a JDialog . When you close a dialog is does not close the main JFrame.

However, for information regarding a JFrame check out the setDefaultCloseOperation(...) method. The default is to "hide" the frame. So if your application is exiting then that means you are probably using the System.exit(...) method somewhere in your code which you should not be doing.

Answer 2

在我要关闭的Jframe的属性中发现defaultCloseOperation设置为EXIT_ON_CLOSE，我将其设置为Dispose。
