My JOptionPane code is as follows:

selectedSiteName = JOptionPane.showInputDialog("Enter the name of the new site:");

This renders out an input with a textbox and an OK and Cancel button. I need to detect if Cancel was clicked.

Cheers.

Check if selectedSiteName == null .
This will be the case if the user clicks Cancel or closes the dialog.
