QNX Screen Environment

The QNX screen composited window system provides the ability for multiple applications to render content to a display at the same time and to have that content merged together.


By default (0), the screen composition manager does not deliver input events to an application that has fully transparent pixel content. This corresponds to the default QNX screen input setting of SCREEN_SENSITIVITY_TEST. Setting the SB_SENSITIVITY option to 1 any touch input received on the applications display area will be delivered to the application regardless of if the pixels were transparent or not. This corresponds to the QNX screen input setting of SCREEN_SENSITIVITY_ALWAYS.
