How to Profile QtQuick applications on Freescale i.MX 6 with vAnalyzer
Quick overview of profiling tools QtQuick is often used to create UIs for embedded devices. One SoC that is quite popular at the moment is the i.MX 6 board from Freescale, with its Vivante GC2000 or GC880 3D GPU. Performance on such a device matters, users expect a fluid interaction. With the QML Profiler, Qt […]
Qt Input Method – In Depth
What is an Input Method and what do we need it for? To answer that question, let’s see what Wikipedia says: “An input method (or input method editor, commonly abbreviated IME) is an operating system component or program that allows any data, such as keyboard strokes or mouse movements, to be received as input.
