QTreeWidget problem!!

[mcenatie]

Hi,

I'm working on an instant messenger application.
I have a class Contact subclassing QTreeWidgetItem and a class with a QTreeWidget attributes. I want to add a Contact in the QTreeWidget with the method addTopLevelItem ( QTreeWidgetItem * item ) ! But when I make that, no contact appears in the QTreeWidget!
So what can I do to paint the contacts?
Is it the good way? Maybe I can use the model-view-controller ! But in this case I don't know how to use my data with the model (in trolltech examples data are only QString whereas my data are Contact)!
Thanks for your help....

Did you set the number of columns for QTreeWidget?

Hello,

did you create your toplevel QTreeWidgetItem with the QTreeWidget as root (item = new QTreeWidgetItem (_treeWidget) ?
