validateUserInterfaceItem (NSDocumentController implementation)

[DELHAISE Thierry]

Hi the list,

I'm developping a Desktop GUI app based on 
NSDocumentController/NSDocument implementation.

The current implementation of NSDocumentController (in 
gnustep-gui(trunk) revision 26587 ) is :

- (BOOL)validateUserInterfaceItem:(id <NSValidatedUserInterfaceItem>)anItem
{
 // FIXME
 return YES;
}

Should the implementation could be :

call NSDocument "validateUserInterfaceItem", and return the return value.

Second , how [[NSDocumentController instance] 
validateUserInterfaceItem:sender] get called ?

Thanks in advance for suggestions.
