Earlier this year I created a Hardware company with a friend to supply to our GSM community and beyond. One of our first products is the SIMtrace Hardware (CC Licensed, actually it should work with any Smartcard). Today I had to wait a bit and decided to convert the CLI application that talks to the firmware to a GUI application. I did this by running the CLI part in a QThread and using QMetaObject::invokeMethod to callback to my GUI.

I started off creating the Qt application with VIM and a browser to help me to remember some function names. After a while I had enough of this and used Qt Creator and enjoyed the auto completion, it had no problem reading our C header files of libosmocore and provided auto completion for these too. Once again I am amazed how nice Qt Creator is and how little code I needed to create the below.
