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.

Marshalling of DateTimes into QVariant isn't implemented yet, but (#_new QVariant DateTime) should work with the following patch: https://github.com/stassats/commonqt/commit/96daa6894111090ff0a52648fd1a730d...
