You are calling the setTabOrder too early. The widgets already exist at this point but are not yet 'setup'.

Try to drop your code sequence into init() after the call to


Make sure to replace 'qq' with a simple 'q' at this point. It is the same thing and provided by Q_Q(KCur ...).

In setupUi (it's the generated code from the Qt-Designer ui file), the taborder will be setup according to the instructions made in Qt-Designer and since they are executed *after* the ctor - where you try to setup the order - they will override what you have done. 

You can find this generated file in the build directory as


Hope this helps. I know, it's not obvious if you have little knowledge about the underlying (Qt-) mechanisms.
