Re: custom options during save in a document app

Hi Fred & Nikolaus,

thank you for your suggestions, they were mostly overlapping, so I was 
confident it was the best way!

by searching on the web I found another important method to override:
- (NSString *)fileTypeFromLastRunSavePanel

which is very important if the new accessory view changes the filetype. 
I found no other way to "set it", since setFileType doesn't work.

I have one problem though: the file extension.

Previously, i was running this in saveDocumentAs (thus "before")
    filepath = [[filepath stringByDeletingPathExtension] 
stringByAppendingString: @".tiff"];
    [self setFileName:filepath];
    [self setFileType: @"tiff"];

that's easy, since I only have one filetype, I could preset the 
extension and normalize it before opening the panel. I may have many 
extensions, because PRICE is "editor" of only TIFF files (or, in the 
future JPEG and a few others) but "opens" all file types supported by GUI.

The best would be that on the change of the filetype popup (don't try 
that on GNUstep yet or, if, substitute PRWindow.gorm file with 
PRWindow.nib, there is a strange bug affecting only gorm).

How can I set the filename with the filepanel running? The filetype is 
not a problem since it gets "set" later cleanly with the method 
mentioned above.
