[Pyobjc-dev] Proper way to call NSDivideRect?

[Michael M. <mic...@gm...>]

Hi, I wanted to call NSDivideRect, which returns two NSRects by reference:

FOUNDATION_EXPORT void NSDivideRect(NSRect inRect, NSRect *slice,
NSRect *rem, CGFloat amount, NSRectEdge edge);

I followed the online docs for how to treat out params in calls, and
came up with this:

  lowerEdgeRect, ignoreme = NSDivideRect(self.currentCellFrame(), 1.0,
lowerRectEdge)

This worked with no complaints on 10.4, but on 10.5 with system
python, I get this:

/Users/mmccrack/Products/Debug/Incoming.app/Contents/Resources/ActionSearchResultsWindowController.py:143:
DeprecationWarning: Not all arguments to an Objective-C function are
present
  lowerEdgeRect, ignored = NSDivideRect(self.currentCellFrame(), 1.0,
lowerRectEdge)

It still works, but the warning bothers me. What's going on there?

Thanks,
-mike

  Try this: use None in place of the pass-by-reference arguments; IIRC  
it's killed this error for me recently. I'm guessing that the bridge  
likes to have all arguments in order now, using None as a placeholder  
for pass-by-reference arguments.

   lowerEdgeRect, ignoreme = NSDivideRect(self.currentCellFrame(),  
None, None, lowerRectEdge)

Experts?  :)

I'll confirm that that does seem to quiet it.

To the admins, then - how can I help with documentation updates?
