Re: [Pyobjc-dev] Modify wrapper or loadBundleFunctions syntax

Thank you, that seemed to work.
By the way, the bug is right there under your nose:
<arg type='{CGPoint=ff}' type64='{CGPoint=**ff**}' />
Change the second ff into dd and it's done.
Should I submit a patch or bug report somewhere?
Groeten,
Pepijn de Vos
