Hello!

I'm having a work with QTreeWidget and I found a problem here in locating an item on it by one of its texts. The idea is the following:

I created a QTreeWidget and I decided to read from a txt file some columns and create items and sub-items in the QTreeWidget with the data collected in the txt. The idea is that in each line of the txt there are some parameters base on date values (02/12/2011, e.g.). The algorithm is supposed to do a research in the QTreeWidget each time a new line is read in the txt and see if there is already an item related to that date. If there is not, a new item is created with that new date and the rest of the line data is used to create a child on that item. By the other hand, if an item with that date already exists, than instead of creating a new item with that date and a child with the rest, the algorithm should create only the child under the already existing item.

But I'm having difficulties in creating a search mechanism to see if there is already an item related to that date. Everything else I already have. I tested the function QList<QTreeWidgetItem *> QTreeWidget::findItems ( const QString & text, Qt::MatchFlags flags, int column = 0 ) const (p.s.: where is the button for Qt functions and classes?), but its not working. By the moment, here is what I have:

Qt Code: 
  1. void AlarmManagment::readExistingAlarms()
  2. {
  3.         v_rewr->openRead2("./Config/Alarms.txt");
  4.  
  5. name:   leituraall = v_rewr->Read();
  6.  
  7.         vr_data = leituraall.section('\t',0,0);
  8.         vr_semana = leituraall.section('\t',1,1);
  9.         vr_hora = leituraall.section('\t',2,2);
  10.         vr_smalldescription = leituraall.section('\t',3,3);
  11.  
  12.         if (!vector_String1.contains(vr_data))
  13.         {
  14.             vector_String1.push_back(vr_data);
  15.             addRoot(vr_data, vr_semana, vr_hora, vr_smalldescription);
  16.             qDebug() << "Item normal sendo colocado: " << vr_data;
  17.         }
  18.         else
  19.         {
  20.             a = ui->Listofalarms->findItems(vr_data,Qt::MatchExactly,1);
  21.             qDebug() << "item ja exite: " << vr_data;
  22.             addChild(a.front(),vr_semana,vr_hora,vr_smalldescription);
  23.         }
  24.  
  25.         if (!v_rewr->attheEnd())    goto name;
  26. }
  27.  
  28. void AlarmManagment::addRoot(QString data, QString semana, QString hora, QString smadesc)
  29. {
  30.     QTreeWidgetItem *itm = new QTreeWidgetItem(ui->Listofalarms);
  31.     itm->setText(0,data);
  32.  
  34.     itm2->setText(0,semana);
  35.     itm2->setText(1,hora);
  36.     itm2->setText(2,smadesc);
  37.  
  38.     itm->addChild(itm2);
  39. }
  40.  
  41. void AlarmManagment::addChild(QTreeWidgetItem *parent, QString sem, QString hour, QString smaldescription)
  42. {
  44.     itm2->setText(0,sem);
  45.     itm2->setText(1,hour);
  46.     itm2->setText(2,smaldescription);
  47.  
  48.     parent->addChild(itm2);
  49. }

while:
Qt Code: 
  1. QList<QTreeWidgetItem *> a;

I'm having problems in dealing with this QList of QTreeWidgetItem in terms of finding the item that has the date in question.
