There was a discussion about that topic two weeks ago on the qt mailing list. I installed the package under Win7 /qt and win32 widgets + Lazarus 1.5 trunk. Its working for me so far, but with qt the keyboard keys CTRL+C / CTRL+V / CTRL+X and the [Delete] key are not working. Can I post these issues here or should it stay separately in the QT mailing list?
Best regards
