Navigate through qlistview items with shortcuts

This forum doesn't work like "Hey, I need a function, could you guys code it for me?" so let's put it this way: what did you try so far?

This forum doesn't work like "Hey, I need a function, could you guys code it for me?" so let's put it this way: what did you try so far?

I'm sorry if I give this impression, but the problem is that I haven't found in the documentation an hypothetically QListViewItemIterator (as in qt3); there is a QListIterator but it not seems usable in my case. My listview is using as model a QSqlTableModel but i have not found in its documentation an iterator or so.

Searching in the forum I have found this discussion, but QItemSelectionModel has

select( const QModelIndex &, QItemSelectionModel::SelectionFlags )

select( const QModelIndex &, QItemSelectionModel::SelectionFlags )

To copy to clipboard, switch view to plain text mode 

which should work but i don't know how retrieve next/previous QModelIndex of the selected item.

See QModelIndex::sibling().

Thanks jpn, sibling was what I need (I'm italian so sometimes i don't understand the use of a function from its name: I had no idea of what was simling; after you pointed me to it I have recovered a thesaurus to get the meaning of that word and discovered that it was the function I was searching for).

Now the final code:

void MainDialog::showPreviuosTitle()
{
	QModelIndex mi = listView->currentIndex();
	if(mi.row() > 0) {
		listView->setCurrentIndex(mi.sibling(mi.row()-1,mi.column()));
		viewTitle(listView->currentIndex());
	}
}
 
void MainDialog::showNextTitle()
{
	QModelIndex mi = listView->currentIndex();
	if(mi.row() < listView->model()->rowCount() - 1) {
		listView->setCurrentIndex(mi.sibling(mi.row()+1,mi.column()));
		viewTitle(listView->currentIndex());
	}
}

void MainDialog::showPreviuosTitle()
{
	QModelIndex mi = listView->currentIndex();
	if(mi.row() > 0) {
		listView->setCurrentIndex(mi.sibling(mi.row()-1,mi.column()));
		viewTitle(listView->currentIndex());
	}
}

void MainDialog::showNextTitle()
{
	QModelIndex mi = listView->currentIndex();
	if(mi.row() < listView->model()->rowCount() - 1) {
		listView->setCurrentIndex(mi.sibling(mi.row()+1,mi.column()));
		viewTitle(listView->currentIndex());
	}
}
