HI,
I have just purchased Ohanaware’s excellent “RetinaKit”.
Does anyone know how (or if it is even possible) to retinaize the actual application icons?
I am talking about the 512, 256, 128, 48, 32, and 16 icons which are dragged into the IDE when setting the app’s icon and mask.
I can’t seem to work out how to do it.
Thank you all in advance.
Unfortunately, Xojo is not able to handle this directly. You will need to create an .icns file that contains all the different sizes and resolutions yourself. I believe the icons need to be named specifically for the system to recognize the retina icons.

It will be nice if/when Xojo ever supports this directly.
Oops! Forgot to mention that you can either do the tweaking yourself for the OS to see your new icons, or use something like AppWrapper to automate the process for you.
So this is not possible with RetinaKit?
I know of, but am unfamiliar with RetinaKit, so I can’t answer this.
Scott,
If I create all the icons and name them as in your screenshot, am I right in presuming that I them simply paste the .icns file into the icon square in the finder’s GET INFO window?
Also, any good software recommendations for creating the.icns file?
Thank you.
The Retina Kit is source code you use in your application to display retina graphics (including in OS controls).
App Wrapper or App Wrapper Mini feature an icon editor that will build Retina ICNS files from either a single image or separate images. You can also use App Wrapper or AWM to insert the Retina icon into your application at build time too.
