I just wanted to know how to to implement badges like in the mail app from osx to my application without using PxSourceList : http://grab.by/nJ66
My app is developed with rubymotion for os x.
Thanks in advance.
As far as I know they are not available "out of the box"... PXSourceList has the best implementation of badges I have seen. Either use PXSourceList or look at the source code for it and be inspired to how it should be done.
