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.
