I'm porting a small application to OS X (on a somewhat painful virtual machine setup) and was wondering whether someone knows how to fill in the some of the missing parts in the code below to make the EditorGadget selection handling more cross-platform. Unfortunately, I have no clue about Cocoa.
I'm posting the incomplete code (assembled from various posts here) because perhaps someone else might it useful. Code: Select all
