The simplest way to achieve this in Java is using Action by extending AbstractAction . The methods you need to call to update your application are invalidate() , validate() or repaint() .
EXIT_ON_CLOSE (defined in JFrame) : Exit the application using the System exit method. Use this only in applications. might still be useful: You can use setVisible(false) on your JFrame if you want to display the same frame again. Otherwise call dispose() to remove all of the native screen resources.
Use anything for setDefaultCloseOperation excepting EXIT_ON_CLOSE . Then, for the cancel button, just dispose() the window. If the application has another running thread, it won't exit. You can also hide a window by calling setVisible(false) .
Try
SwingUtilities.updateComponentTreeUI(frame); If it still doesn't work then after completing the above step try
frame.invalidate(); frame.validate(); frame.repaint(); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
