How can i set QStandardItem in the row which have parents?
For example:

I need set item here, but there is no functions which would allow to do it.
There is to functions to set item:
setItem ( int row, int column, QStandardItem * item )
setItem ( int row, QStandardItem * item )
But they dont have parent argument

I don't understand your problem.
If you want to set a tree with 3 levels , you just have to do :

@QStandardItemModel *model = new QStandardItemModel;
QStandardItem * level0 = new QStandardItem("level 0");
QStandardItem * level1 = new QStandardItem("level 1");
QStandardItem * level2 = new QStandardItem("level 2");

level1->appendRow(level2);
level0->appendRow(level1);

model->appendRow(level0);@

And , then because everything are pointers, you can set items directly

Otherwise, maybe you want to set items by clicking on it .

From the view ( treeview, listview...) get the the index by using the signals :
@void clicked ( const QModelIndex & index )@

Then, get the standardItem from the index and change it as you want !
@QStandardItem * itemFromIndex ( const QModelIndex & index ) const@

If I understand correctly, there is no analog of QStandardItemModel::setItem() (which applies for tables) in the context of a tree structure. If I want to fully change an item at a given position in my tree, first I have to cut the branch beneath the parent (removeRow()) and second, graft there the new item (insertRow()). Am I wrong?

Second thought: please forget, forgive or delete this post, the answers above are clear.
