Dear reader,

I'm using a javax.swing.JFileChooser to browse my harddisk.
I want to issue a warning message when the user presses the 'open'-button
without actually selecting a file.
The JFileChooser treads this as if the 'Cancel'-button was pressed. So, now
the warning also appears when the user presses the 'Cancel'-button.
What should I do?
How can I detect which button was actually pressed?

I'm looking forward to your reply.

Thank you in advance.
