Is it possible to have a different set of toolbar graphics for Windows and Mac programmatically? .. on account windows doesn't scale at all. Thanks Windows.
Maybe I don't understand the challenge, but if you do want to use the same images for your toolbar buttons for both Mac & Windows, I think this does work, providing you setup your images correctly.
I'm using Xojo 2019r1.1 and my current project has a toolbar and the images look and scale the same on Mac & Windows 10 (whether 100, 150 or 200%).
In my case, I added some images ("Insert" menu > "Image"), then added three sized *.png images for my icons, starting at 32x32 (@1), then 64x64 (@2) and 96x96 (@3). These sized versions should be accurate for each size (true 32x32, 64x64 & 96x96 representation of the image), and not a rescaled version of the same original image that you've resized yourself in an image editor - if that makes sense?
Then from the Toolbar Inspector, I selected my images from the "Icon" drop-down for each of the buttons. When I run the app, the appropriate image should show for the given screen scaling.
The only annoying difference I found with the Toolbar is that Windows doesn't support the Flexible Space feature. But I can live with that.
Or is this a problem for older versions of Windows than 10?
I hope some of this helps.
