```
public abstract class UserQuestionException
extends java.io.IOException
```
Exception that is thrown when the process is about to perform some action that requires user confirmation. It can be useful when there is a call to a method which cannot open a dialog, but still would like to ask the user a question. It can raise this exception and higher level parts of the system can/should catch it and present a dialog to the user and if the user agrees reinvoke the action again.
The getLocalizedMessage method should return the user question, which will be shown to the user in a dialog with OK, Cancel options and if the user chooses OK, method ex.confirmed () will be called.
Since version 8.29 one can just catch the exception and report it to the infrastructure of any NetBeans Platform based application (for example via Exceptions.printStackTrace(java.lang.Throwable)) and the question dialog will be displayed automatically.
