It has been a few months since my last update about the Windows Embedded Compact (WEC) port of Qt. But as I promised last time, I have been working on the WEC2013 support for Qt. Not only because it’s the new embedded platform from Microsoft, but also because Qt wants to adopt more C++11 in […]
How to use static analysis to improve performance
It’s usually said “only improve performance where a profiler tells you to“. I don’t completely agree. Take a big C++ library like Qt: can you profile all classes and all code paths ? It would take a couple of years to accomplish and analyse the results. It’s expensive: It usually only happens if the speed-up […]

Qt Input Method – Virtual Keyboard Implementing an out-of-process virtual keyboard for text input in Qt apps
In the last episode of this blog series we learned about the overall concepts of input methods in Qt, with a look behind the scenes to see how a key press event from the native windowing system travels through the Qt input stack until it appears on screen inside a QLineEdit. In that context, the input method […]
Qt and KDAB at CppCon 2015

I have fond memories of watching GoingNative 2012 in a live stream with some colleagues of mine in our office in Berlin. But, over the years, […]

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. In […]
