Profiling QtQuick HMI Performance on Embedded Linux - Video
30 August 2017
QtQuick is a popular choice for creating HMIs for embedded devices. The hardware on these devices often is constrained and less performant than their desktop equivalents, this requires extra care from software developers in delivering a fluid user experience. KDAB is regularly involved with improving the performance of QtQuick HMIs on such devices for their customers.
In this demonstration, we will show how to profile and optimize the performance of a QtQuick speedometer, an example taken from an actual embedded project running on an i.MX6 board. We will show how to identify the performance bottleneck with the QML profiler in QtCreator, followed by pointing out possible solutions and then choosing the best one.(Voice by Wieland Hagen)
