QTableView: how do I correctly create a QModelIndex?
I'm trying to enter edit mode on a specific cell like this:
void MainWindow::on_addButton_released() {
tm->addRow();
tableView->scrollToBott开发者_StackOverflowom();
int ec=tm->firstWritableColumn();
int r=tm->rowCount(QModelIndex());
QModelIndex id = tm->index(r, ec, QModelIndex());
tableView->setCurrentIndex(id);
tableView->edit(id);
qDebug() << "row:" << r << " col:" << ec << "index:" << id;
}
My model creates an index like this:
QModelIndex TableModel::index(int row,int column,QModelIndex parent) const {
Q_UNUSED(parent);
return createIndex(row,column,0);
}
The debug output looks like this:
row: 9 col: 1 index: QModelIndex(9,1,0x0,TableModel(0xbf3f50) )
I'm fairly sure that the index is somehow invalid as setCurrentIndex()
doesn't seem to be working.
OMG! ground swallow me up!
row numbers start with row 0, I needed to do
int r=tm->rowCount(QModelIndex())-1;
QModelIndex id=tm->index(r,ec,QModelIndex());
