Split screen function not working properly

The split screen functionality in Code View mode of the AppDesigner does not work properly: The right side stays empty when chosing Left/Right (empty lower half for Top/Bottom) and doesn't show any code at all, no line numbering is indicated on that side:

I am using 2023b in the current release 6. When switching back to 2023a, the issue doesn't appear.

Can I fix this from my side? Thanks for your support.

Hi Martin,

I too faced the same issue in the R2023b, while using the split screen functionality in Code View mode of the AppDesigner.

Below is a workaround to resolve the issue,

• Go to the Code view of the App Designer of your project
• Select any of the Split screen view in the "Code View", either "Left/Right" or "Top/Bottom". As mentioned, the Split screen appears with a Blank view.
• Switch to "Design View", and then switch back to "Code View", and the code populates in both screens.

That's an easy fix I could have found on my own - thanks a lot!

I'm glad I found this comment. It works. I was pulling my hair out trying to figure out what was wrong with the split screen. :)

I hope Mathworks fixes this.
