Parent Window Closing when Closing Child Window

Question

I have an application that creates a new window (let's call it Cuprins) when a button of the same name is pressed. The problem I have is that when I close the new window, it also closes the main one. Is there anyway to make the main window not close when closing the Cuprins window?

See [The Use of Multiple JFrames, Good/Bad Practice?](http://stackoverflow.com/a/9554657/418556) (But see also `JFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE)` as seen in [this answer](http://stackoverflow.com/questions/7143287/how-to-best-position-swing-guis/7143398#7143398) for the immediate 'fix'.) — Andrew Thompson, Dec 31 '12 at 15:19

Check what's the default close operation. Set it to "dispose on close" or "do nothing on close"

The newly opened window should use dispose on close to dispose the frame, or setVisible(false) to hide it temporarily.

Just use this line while you creating child window.

myFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

Usage example :

AddLeagues addLeague = new AddLeagues(); //Child View
addLeague.setVisible(true);
myFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
