There are a number of things done automatically to simplify UI development for mobile. First, all PowerBuilder UI controls are rendered as touch-friendly mobile UI controls. Second, mouse movements are automatically mapped to mobile gestures, for example tap to click, swipe to scroll, pinch to zoom, and so on. Third, automatic UI-resizing APIs are provided to dynamically scale your screen, or simply go with our fixed settings for automatic scaling. And finally, APIs are provided to give you control over how the UI is presented, for example limiting to particular device type (e.g. tablets) and locking screen orientation (e.g. landscape).
