Inserting QStandardItems to the child rows and columns in QStandardItemModel

[ru_core]

Hi all!
There is code which helps to build the tree (picturied lower)


#include <QtGui>

int main(int argc, char** argv)
{
QApplication app(argc, argv);
QStandardItemModel model(5, 3);

for (int nTopRow = 0; nTopRow < 5; ++nTopRow) {
QModelIndex index = model.index(nTopRow, 0);
model.setData(index, "item" + QString::number(nTopRow + 1));

model.insertRows(0, 4, index);
model.insertColumns(0, 3, index);
for (int nRow = 0; nRow < 4; ++nRow) {
for (int nCol = 0; nCol < 3; ++nCol) {
QString strPos = QString("%1,%2").arg(nRow).arg(nCol);
model.setData(model.index(nRow, nCol, index), strPos);
}
}
}

QTreeView treeView;
treeView.setModel(&model);
treeView.show();

return app.exec();
}

My task is to insert QStandardItems in the child rows and columns.
tried

void QStandardItemModel::setItem ( int row, int column, QStandardItem * item )
but but the model did not change the count of its rows and columns after new rows and colums have been inserted

do you have any ideas?
Thank you

Where is your code calling setItem()?

Where is your code calling setItem()?

I just tried to insert it, but have no ideas how to set the Items to the inserted rows
