The iControlPad didn’t work in keyboard mode with Symbian devices, so I decided to make my own support library for it. The iControlPad is working on SPP mode as default, and that mode support also the analog nubs, so I decided to write support for it. You can get the support library from GitHub: https://github.com/Summeli/iCP4Qt Integrating [...]

Fast blit with OpenGl ES and Qt
In my previous post I wrote about blit with opengl es 2.0 texture upload. However I noticed that using just Qt’s QGLWidget and implementing only the paintEvent is as fast as the texture upload with pure OpenGL ES API. I guess that QGLWidget is making the drawing via OpenGL, since the performance seems to be [...]
Fast Blit with OpenGL ES 2.0 and texture uploading
OpenGL ES 2.0 is fully shader based, which means you can’t draw any geometry without having the appropriate shaders loaded and bound. This means there is more setup code required to render than there was in OpenGL ES 1.1 with fixed pipeline. Setting up the OpenGL ES 2.0 pipeline. The actual drawing is done in [...]
Building Symbian Projects with QtSDK
All new Symbian SDKs are now distributed inside the new QtSDK, so that should be my primary build environment. The new QtSDK also includes an updated version of GCCE (4.x), and new sbsv2 build, which is a lot better than the old symbian abld-build. With this tutorial you can still build your old symbian projects [...]

The good news is that you can write your own style, and use it in your own application. Here’s a [...]
