auto checkox fresh in qtreeview problem.

Didnt emit dataChanged work for you ?

Also try calling view->update();

solved by emit dataChanged signal for every model item that change check state.

oh,it does not solved, there must be something wrong, though i have emit every datachange signal for every change item, qtreeview doesn't refresh well.
may be i don't have write the right code, but it seems beyond my brain now.
i have attach a test demo.

[yj_yulin]

my compile info: qt 4.6.2 on win xp sp3 with vs2008.
it doesn't use any windows special, it should compile everywhere that qt supported.

[yj_yulin]

when compile with qt 4.7 beta1, the same effect as 4.6.2.

[yj_yulin]

seems solved by rewrite method
//-------------------------------------------------
void TorgTreeModel::emitDataChanged( TorgTreeItem* item )
{
TorgTreeItem* parent_item = getOrgItem(item->parent_org_id);
emit dataChanged(createIndex(item->row(),0,parent_item),createIndex(item->row(),1,parent_item));

qDebug() << "datachange" << item->org_full_name;
}
