FileDialog from Spec

In Pharo 4.
I'm writing a ui in spec and I want to be able to select and open a file on a button click.
I can see one example in polymorph but I don't know if that can be used from spec.
Or am I missing something obvious?
 

I just want to call a dialog on a button click.

What approach do I take with the Polymorph one?
Do I have to open a Polymorph window which then calls the dialog or can I bake the Polymorph dialog into my spec window?

Hi Jeff,
Here is an example to bring up the file dialog answering a file reference.

| reference |
reference := UIManager default
  fileSave: 'Save as?'
  extensions: #('pdf' 'png' 'stuff')
  path: Smalltalk imageDirectory.

For other examples see MorphicUIManager where methods start with file*

Best regards,
Henrik

Thanks! That worked like a charm.
