سؤال
QTableWidget have a method to search for a row with user data?
Something like:
//set user data
row->setData(0, Qt::UserRole, "ID001");
//find row by user data
int rowIndex = table->findByData("ID001");
المحلول
You can use QAbstractItemModel::match()
QAbstractItemModel *model = table->model();
QModelIndexList matches = model->match( model->index(0,0), Qt::UserRole, "ID001" )
foreach( const QModelIndex &index, matches )
{
QTableWidgetItem *item = table->item( index.row(), index.column() )
// Do something with your new-found item ...
}
