I refactored a project because it weighted 22MB.
So, I deleted all images / icons and loaded them at need time (run time).
The project is now < 250KB.
So far, so good, I added two icon files (.icns) with a script and the one for the application appears once I build the application.
But… how do I set the Custom Icon to the Custom file ?
This is for old Xojo users because the project is running on 2015r1.
Nota: when the icon was set in the FileType entry, the document does not have that icon.
I searched in the local documentation, but failed to get info. I do not found that the application icon file must be named “App.icns”… but this I remember.
Conclusion: when you stop using a knowledge, it slowly disappear (faster when you’re an oldster).
