How can i select a row at startup

[kosasker]

i want to select a treeview row at startup

QModelIndex index= new QModelIndex(1,0,void ????, model);
ui->treeView->setRootIndex(index);

QModelIndex index= new QModelIndex(1,0,void ????, model);
ui->treeView->setRootIndex(index);

To copy to clipboard, switch view to plain text mode 

i dont know how can i do it... i just want to select a row at startup... please help!!!

Edit:

I cant understand model/view arch. logic... i read local help files, looked at samples too...

I can get index of the selected items, but i cant store them (in textfile or registry) Gone a be crazy...

Also i tried to give row and coloumn numbers manually, but i cant do it. if i can select it manually on start up, my problem will be solved... Please help...

You can't create model indexes by yourself. Only the model can create an index.

QModelIndex index = model->index(1, 0); // row = 1, column = 0, top-level item (invalid parent)
ui->treeView->setModel(model);
ui->treeView->selectionModel()->select(index);

QModelIndex index = model->index(1, 0); // row = 1, column = 0, top-level item (invalid parent)
ui->treeView->setModel(model);
ui->treeView->selectionModel()->select(index);
