Re: [udig-devel] fileFormat extension point

[Jody Garnett <jody.garnett@xxxxxxxxx>]

I will say "yes" - but we may need to think through what you would expect.

But we may need to figure out how ... the SWT File open dialog is really focused on using a set of strings which it uses to filter the files. Indeed each platform has a very different file open dialog - on windows it only shows my files that match one of the available extensions; on mac it shows me all the files ... but the ones that do not match are greyed out.

So if we can review what SWT (or JFace) offers and sort out a way to recognise folders we can add to the fileFormat extension point.
