Extending a save panel

I want to add popup button to my save panel so that I can save file in
different formats. When the document is created I don't know what
format the user will want to save it in. So, I want to allow them to
choose from the pop up.

So, I added an NSPopUpButton to the panel using prepareSavePanel. I
thought I could use setTarget and SetAction to catch the changes in the
pop up. It builds OK and the pop up is there but when I used SetAction
the pop up is disabled, otherwise it looks OK.

I think maybe I'm going about this all wrong. Can someone tell me the
right way to do it ? Here some snippets from MyDocument.m:

- (void)setDSCFileMode:(id)sender
{
   int val = [sender intValue];
} // setDSCFileMode

- (BOOL)prepareSavePanel:(NSSavePanel *)savePanel
{
   NSPopUpButton*    saveModeButton;    // mode to save file in (Mac or Windows)
   NSRect bRect = {0, 0, 130, 30};

   saveModeButton = [[NSPopUpButton alloc] initWithFrame:bRect
pullsDown:NO];
   [saveModeButton addItemWithTitle:@"Mac OS"];
   [saveModeButton addItemWithTitle:@"Windows"];

   [saveModeButton setTarget: self];
   SEL tellMeAboutIt = @selector(setDSCFileMode);
   [saveModeButton setAction: tellMeAboutIt];
   
   [savePanel setAccessoryView: saveModeButton];
   return YES;
} // prepareSavePanel
