[Gambas-bugtracker] Bug #2364: Missing Filter Index Property in the SaveFile Dialog

Claus DIETRICH reported a new bug.

Summary
-------

Missing Filter Index Property in the SaveFile Dialog

Type             : Request
Priority         : Medium
Gambas version   : 3.15
Product          : Unknown


Description
-----------

I wanted to access the selected filter of a SaveFile-dialog which is an element of the filter array. This is indispensable if something like this is required:
Dialog.Filter = ["*.pdf", "PDF File", "*.pdf", "searchable PDF File"]
Since the processing of normal PDF and a searchable PDF is completely different, I need no know what the user selected in the filter-combo of the SaveFile-dialog. Since I couldn't find any function which allows this (please inform me if I missed one) I hereby request to add a Filter-Index, i.e. like available in Visual Basic 6 and .Net.

My proposal:

Adding the Property Index to the "Filter"-array as follows:
 
Dialog.Filter.Index  (Determines which filter shall be used as default or returns the index of the selected filter)

This may also apply to the OpenFile-dialog.

Best regards
Claus
