Create a button with the label 'Browse...'
When the user clicks on the button, execute the following command:
result = dialog_pickfile()
If the returned value is not the null string (''), then a valid filename
was selected. See the online help for the keywords supported by
dialog_pickfile.
There is also a file selector compound widget (cw_filesel) that you
could use, but I prefer dialog_pickfile.
Cheers,
Liam.
