"We are not using directfb library or any of its API in our Qt application. Rather we have set QWS_DISPLAY = directfb which is to use directfb as the driver for the framebuffer to which we are directing our Qt application output. I think we have some problem in the directfb code. I am using Directfb-1.4.14. May be we are not using the directfb properly." -- ** _________________________ Pravinkumar Chavan Software Engineer +919867107370 En Route Media Pvt. Ltd. ** *_________________________* * *
