[Qt-interest] QPlainTextEdit Ctrl+K shortcut under Windows

[Roland Krause]

Well, I hate to have to reply to my own post but I dug into the issue a bit and was wondering whether there is 
a clean way to change the standard QKeyBindings for QKeySequence::DeleteEndOfLine to get "Ctrl+K" to delete to the end of the line under Windows, i.e. short of changing the source code in the Qt libraries "qkeysequence.cpp" file. 

QKeySequence allows access to a QKeySequencePrivate * via its public data_ptr() function but accessing that is no
good because one has to include qkeysequence_p.h which is as I understand a "no no". And when I try it anyway I end up with two unresolved symbols: QKeySequencePrivate::keyBindings and QKeySequencePrivate::numbderOfkeyBindings which as I understand result from the declaration of the QKeySequencePrivate class at build time of the Qt library. 

Does anybody have a suggestion what to try now?

I'd be greatful for any ideas.

Thanks,
Roland
