Yes, refer to the setFilterMask() method
The sytnax differs on mac and Windows. Off the top of my head, on the Mac, it takes
four character type codes, such as "TEXT". On the PC, it takes a name and an
extension, such as "Text Files, *.txt".
So it would be something like this for text files (untested off the top of my head)
fileObj = new (xtra "fileio")
if the platform contains "Windows" then
setFilterMask (fileObj, "Text Files, *.txt"
else
setFilterMask (fileObj, "TEXT")
end if
displayOpen (fileObj, whatever...)
Don't forget to set the file type using setFinderInfo as I recall) if you are writing
out your files on the Mac. Otherwise, when you set the filter mask, you won't be able
to see the files you've previously written (i.e. they won't appear in the dialog box
if they have the wrong type)
If you can't figure it out, let me know. Many more details are in the External Files
chapter in Lingo in a Nutshell.
