How to select several cells from a QTableWidget?

[xtingray]

Hi,

I need to select an specific range of cell items in a QTableWidget object directly from my code. My input is a list with the cell coordinates (int column. int row) that makes part of the selection. Example of input: [0, 1] [0, 2] [0, 3]

Any hint?

PS: I found this piece of code and I wonder if there's a way to create my own QItemSelection object, assigning the items I want to select. Is it possible?

QItemSelection selectedItems = tableView->selectionModel()->selection();
tableView->selectionModel()->clearSelection();
tableView->selectionModel()->select(selectedItems, QItemSelectionModel::Select);

Have You read the QItemSelectionModel reference page?
It seems to be what You need.

void selectIndexes(const QModelIndexList& indexes){
tableWidget->selectionModel()->clearSelection();
for(auto& singleIdx : indexes)
tableWidget->selectionModel(singleIdx , QItemSelectionModel::Select);
}

I know I 'm in the right direction, but there is a point where I got stuck: if I can instance items of the QModelIndex class using the coords I already have, I can solve my problem easily as in the example you suggest... but how?

Checking the QModelIndex method s, there is no set actions of any kind. How can I define a QModelIndex with the cell position (column, row), i.e. (0,1)? I have been reading the view/model documentation but I must confess I am lost about this specific topic :(

easy!
tableWidget->model()->index(row,column);

Don't forget to set :

void setSelectionMode(QAbstractItemView::SelectionMode mode)
setSelectionBehavior(QAbstractItemView::SelectRows);
