How to get parent of selected item in TreeView?

[caduel]

QTreeWidgetItem *item = treeWidget->currentItem();
value = item->data();
QTreeWidgetItem *item_parent = item->parent();
if (item_parent) ....

QTreeWidgetItem *item = treeWidget->currentItem();
value = item->data();
QTreeWidgetItem *item_parent = item->parent();
if (item_parent) ....

To copy to clipboard, switch view to plain text mode 

I suggest not to use the "DisplayRole" here.
I would add a custom role for each item that contains the QDate so you don't have to build up dates from displayed data. Maybe another role that tells you if it is a year/month/day item.
(You just have to figure out how you represent months and so on (a QDate can't have a day value of 0.)

Huh, thank you very much! I just didn't saw this method.

And also thanks for suggestion, I'll think about it.
