Many aspects of the UI for mobile applications differ significantly from traditional PowerBuilder best practices. How you layout controls on the window, the size of the window, controls, and other visual objects, and how the user expects to interact with your application are fundamentally different for mobile devices.
Please carefully read Best Practices in Mobile UI Design & Development Guide, including the Window subsection. We have compiled valuable tips and suggestions that will help you develop user-friendly mobile applications.
Once you have a good understanding of Best Practices in Mobile UI Design & Development Guide, we strongly recommend using the formula in the section called “Unit conversion” in Mobile UI Design & Development Guide to properly size the application windows and controls to display appropriate on the mobile device.
