Qt4 : QListView : programmatically selecting an item
Message 1 in thread
Hi,
With Qt4, I'm using a QListView, displaying a QStringListModel.
Once the model has been set to the view, I want to programmatically select
one of the displayed items, but I didn't find any methods like
'setCurrentItem' or 'selectItem'...
How can I do that ?
Thanks for your help,
Jerome

There's QAbstractItemView::setCurrentIndex. You will need to get a
QModelIndex pointing to the model entry you want to be selected. With a
QStringListModel, this should be as easy as model->index(row, 0), where
row is the position of the string in the string list.

Selections are outsorced to QItemSelectionModel; see
QAbstractItemView::selectionModel(). BTW, this is a FAQ; you may want to
save time by searching the archives of this list...
