View source for FAQ How do I inform the user of a problem?

Warnings and errors can be reported to the user by using an <tt>ErrorDialog</tt>.
Here is a very simple example of an Error dialog displaying a warning message:
<pre>
   IStatus warning = new Status(IStatus.WARNING, 
      ExamplesPlugin.ID, 1, "You have been warned.", null);
   ErrorDialog.openError(window.getShell(), 
      "This is your final warning", null, warning);
</pre>



The <tt>null</tt> parameter to the status constructor is for supplying an exception
object.  The exception object is not used by the Error dialog, so we&#146;ll leave it blank
in this case.  If you&#146;re creating a status object for another purpose, such as logging,
you&#146;ll want to supply the exception, if there is one.  The <tt>openError</tt> method
has parameters for a title and a message, but both of these parameters are optional.  If you don&#146;t
supply a title, the method will use the generic '''Problems Occurred''' message.  If
you don&#146;t supply a message, the method will take the message from the supplied status object.
