Posted in Declarative UI, Dev Loop, Embedded, Graphics, Performance, Qt Quick

Qt Quick-based user interfaces have traditionally been requiring OpenGL, quite unsurprisingly, since the foundation of it all, the Qt Quick 2 scenegraph, is designed exclusively with OpenGL ES 2.0 (the top of the line for mobile/embedded at the time) in mind. As you may have heard, the graphics API story is a bit more inclusive […]

Qt on the NVIDIA Jetson TX1 – Device Creation Style

Published Thursday November 10th, 2016 | 4 Comments on Qt on the NVIDIA Jetson TX1 – Device Creation Style
Posted in Dev Loop, Embedded, OpenGL, QPA, Qt, Qt Quick

NVIDIA’s Jetson line of development platforms is not new to Qt; a while ago we already talked about how to utilize OpenGL and CUDA in Qt applications on the Jetson TK1. Since then, most of Qt’s focus has been on the bigger brothers, namely the automotive-oriented DRIVE CX and PX systems. However, this does not […]

Qt Graphics with Multiple Displays on Embedded Linux

Published Monday September 19th, 2016 | 8 Comments on Qt Graphics with Multiple Displays on Embedded Linux
Posted in Automotive, Dev Loop, Embedded, Graphics, OpenGL, QPA, Qt Quick

Creating devices with multiple screens is not new to Qt. Those using Qt for Embedded in the Qt 4 times may remember configuration steps like this. The story got significantly more complicated with Qt 5’s focus on hardware accelerated rendering, so now it is time to take a look at where we are today with […]

Creating Certified Medical Devices with Qt

Published Wednesday September 7th, 2016 | 1 Comment on Creating Certified Medical Devices with Qt
Posted in Biz Circuit, Embedded, Medical

Many modern medical devices provide a graphical interface to the user. In dialysis machines, for example, touch screen interfaces to set up the treatment parameters and to monitor the treatment progress are commonplace. Qt is a viable technical solution to implement those interfaces, so it is used in quite a number of medical devices. When […]
