How to make checked and disabled a QTreeWidgetItem

[jlbrd]

Hi,
I want to set checked AND disabled an QTreeWidgetItem on QTreeWidget but :

If I use :
QTreeWidgetItem *item = new QTreeWidgetItem(itemParent, "myText");
item->setCheckState(0, Qt::Checked );
item->setFlags( Qt::ItemIsUserCheckable | Qt::ItemIsEnabled );
Item is checked but not disabled

and if I use :
QTreeWidgetItem *item = new QTreeWidgetItem(itemParent, "myText");
item->setCheckState(0, Qt::Checked );
item->setFlags( Qt::ItemIsUserCheckable | Qt::ItemIsSelectable );
Item is disabled but not checked

Thanks
