146 /* Try to determine if the application is a foreground Cocoa application.
147 In Jaguar, itÕs possible to mix Cocoa in a primarily Carbon application,
148 but we don't support such hybrids because the menu items we add depend
149 on Cocoa dispatch mechanisms.
150
151 The CPS 'flavor' mechanism (isCarbon, isCocoa) is broken in Mac OS X
152 10.1.2 through 10.1.5 and possibly earlier, reporting that all Cocoa apps
153 are Carbon apps. So we use some code extracted from otool to check
154 whether the application links to the Foundation, AppKit or Cocoa
155 frameworks. This problem is fixed in Jaguar, except that certain CFM
156 Carbon apps are reported to be Cocoa apps (Drop Drawers is one example).
157 Conversely, the appIsCocoa: code works on _most_ applications, but
158 Jaguar always correctly identifies Cocoa apps as isCocoa.
159
160 So, our checks go like this:
161 Is the application background-only?
162 Is the application Cocoa or Carbon according to the CPS flavor?
163 If it's Cocoa, is it a CFM app? If so, CPS is lying to us.
164 If it's "Carbon", does it link to AppKit, Foundation or Cocoa?
165 If so, it's really a Cocoa app. If not, it's a Carbon app.
166
167 Be careful not to call appIsCocoa: on a Classic application, you will
168 crash.
