I have a QStandardItemModel, which I display in q QTreeView. Works fine.

To highlight relevant rows I want to highlight some of them: Therefore I have a QStringList with the names of the QStandItem* s to be highlighted.

QStringList namesToBeHighlighted = getNames();

QModelIndex in = myModel->index(0, 0);

if ( in.isValid() ) 

 for (int curIndex = 0; curIndex < myModel->rowCount(in); ++curIndex) 

 QModelIndex si = myModel->index(curIndex, 0, in);
 QStandardItem *curItem = myModel->itemFromIndex(si);

 if (curItem) 
 QString curItemName = curItem->text();

 if ( namesToBeHighlighted.contains(curItem->text()) ) 
 curItem->setFont(highlightFont);
 
 else curItem->setFont(unHighlightFont);
 
 

My Model has following structure:

Level_1

+--> Level_11

+--> Level_12

+--> Level_13

Level_2

+--> Level_21

+--> Level_22

+--> Level_23

...

Here, it iterates trough Levels 11, 12 and 13 then it stops.

I hope it helps you:

void forEach(QAbstractItemModel* model, QModelIndex parent = QModelIndex()) 
 for(int r = 0; r < model->rowCount(parent); ++r) 
 QModelIndex index = model->index(r, 0, parent);
 QVariant name = model->data(index);
 qDebug() << name;
 // here is your applicable code
 if( model->hasChildren(index) ) 
 forEach(model, index);
 
 


QStandardItemModel model;
 QStandardItem* parentItem = model.invisibleRootItem();
 for (int i = 0; i < 4; ++i) 
 QStandardItem *item = new QStandardItem(QString("item %0").arg(i));
 for (int j = 0; j < 5; ++j) 
 item->appendRow(new QStandardItem(QString("item %0%1").arg(i).arg(j)));
 
 parentItem->appendRow(item);
 parentItem = item;
 
forEach(&model);
