I am trying to build qtvirtualkeyboard plugin following this instructions with arrow-key-navigation option enabled. But I don't understand how to enable it in the right way. I have tried to add
CONFIG += arrow-key-navigation
into qtvirtualkeyboard.pro without any success. When I add
DEFINES += QT_VIRTUALKEYBOARD_ARROW_KEY_NAVIGATION
into src/virtualkeyboard/virtualkeyboard.pro it works, but I think this is the wrong way.
The sources should be pristine and you shouldn't be touching them. Delete the decompressed sources, and reinstall them.
The configuration options are passed to qmake, on the command line. E.g., assuming an out-of-source build (the only sane way!):
qmake /path/to/qtvirtualkeyboard.pro CONFIG+=arrow-key-navigation
These options can be specified in Qt Creator's build settings: there's a place to add qmake command line options to.
