Hi,
I sort of ported one of the Qt4 Tutorials on Models to commonqt, because I want to get to know both Qt4 MVC stuff and commonqt a bit. I more or less just wrote the C++ Code in Lisp syntax. However, there is an error with the bit of code that calls setData (I attached the relevant code):
No applicable method setData found on #<QStandardItemModel 0x00886620> with arguments (#<QModelIndex 0x007817A0> #<QDateTime 0x00889540>) [Condition of type SIMPLE-ERROR]
I tried wrapping the QDateTime object in a QVariant, but that doesn't help, I get a similar error:
No applicable method setData found on #<QStandardItemModel 0x008894D0> with arguments (#<QModelIndex 0x0088A130> #<QVariant 0x0088A2E0>) [Condition of type SIMPLE-ERROR]
Qt Documentation says setData expects a QVariant& as the last parameter, but I have no clue how to make one of these. Also, setData works fine with strings.
I use sbcl 1.0.40.0.debian on Debian Squeeze, amd64 and the latest commonqt installed via quicklisp (20110320-git).
Can anybody help me? I'd like to understand where this problem comes from.
Thanks a lot, Olaf Merkert
