---|
176 | In Jaguar, itÕs possible to mix Cocoa in a primarily Carbon application, |
---|
177 | but we don't support such hybrids because the menu items we add depend |
---|
178 | on Cocoa dispatch mechanisms. |
---|
179 | |
---|
180 | The CPS 'flavor' mechanism (isCarbon, isCocoa) is broken in Mac OS X |
---|
181 | 10.1.2 through 10.1.5 and possibly earlier, reporting that all Cocoa apps |
---|
182 | are Carbon apps. So we use some code extracted from otool to check |
---|
183 | whether the application links to the Foundation, AppKit or Cocoa |
---|
184 | frameworks. This problem is fixed in Jaguar, except that certain CFM |
---|
185 | Carbon apps are reported to be Cocoa apps (Drop Drawers is one example). |
---|
186 | Conversely, the appIsCocoa: code works on _most_ applications, but |
---|
187 | Jaguar always correctly identifies Cocoa apps as isCocoa. |
---|
188 | |
---|
189 | So, our checks go like this: |
---|
190 | Is the application background-only? |
---|
191 | Is the application Cocoa or Carbon according to the CPS flavor? |
---|
192 | If it's Cocoa, is it a CFM app? If so, CPS is lying to us. |
---|
193 | If it's "Carbon", does it link to AppKit, Foundation or Cocoa? |
---|
194 | If so, it's really a Cocoa app. If not, it's a Carbon app. |
---|
195 | |
---|
196 | Be careful not to call appIsCocoa: on a Classic application, you will |
---|
197 | crash. |
