[Qt-interest] userdata and qtcombobox items

[cbruner at quadro.net]

I'm sure there must be a way to do this properly. I'm trying to pass 
around a const pointer to an instance using a combobox, so the item in 
the combobox is matched to my pointer.



class myclass {..}

...

const myclass *mc = ....
ui->comboBox->addItem(QIcon(":/images/in.bmp"),a,mc);


...

const myclass *mc = ui->comboBox->itemData(index);


Can this be done in a proper way.  I've looked at Qvarients, and 
Qmetatype and qusertypes docs, but what I need is an example.
