I'm not sure where this question belongs: here or in the "Compiler/IDE forum". But will post here, since it is more close describe my issue.
From here
However, my understanding is that on OSX/Xcode the bitmap file name should be "open@2", to be properly used with HighDPI/Retina display.Of course, this code relies on actually having the resources with the corresponding names (i.e. open_NxN) in MSW .rc file or Mac application bundle and open_NxN_png arrays being defined in the program code, e.g. by including a file generated with bin2c (see wxBITMAP_PNG_FROM_DATA()), on the other platforms.
Will that code work OK there? Is it going to map the file name appropriately?
I don't have Retina Mac, so can't test it...
Thank you.
