QStandardItem setCheckable(true) dosn't save checkbox state

[umen242]

i have simple QStandardItemModel that holds the date to show in QTreeview
when i set one off the columns with :
@items.insert(1,new QStandardItem());
items.at(1)->setCheckable(true);
m_model->insertRow(0,items);@

then i check the checkbox , and close the QDialog that holds the Qtreeview .
when i open the QDialog box again the state dosn't saved . i dont build it again , all the other columns that are text
are saved in the view .
what im doing wrong , i dont what to loop and save the states over and over .

you need set check state by dafault.

@
void QStandardItem::setCheckState ( Qt::CheckState state )
@

this is just only say that user can change state
@
void QStandardItem::setCheckable ( bool checkable )
