[SOLVED] How to programattically select row in QTreeView?

[TOMATO_QT]

I have a simple image browser app with a QTreeView backed by a QFileSystemModel instance. The user is able select a directory using a QFileDialog. I have it working but I would like to automatically select the first item in the new directory.

I've searched around and tried many bits of code without success. I am able to set the QTreeView selection through a button press (as well of course as clicking on the QTreeView).

My code is below. The console output from the qDebug statement:

idx row 0 0
first row 0 0

idx is the selected directory index, and I don't know how to tell the treeView to select the first item within the directory.

Am I doing something obviously wrong? Any help appreciated as I've been stuck on this a while.
Setup: OSX 10.7.5 - Qt 5.1 - desktop app.

void DirBrowser::loadDirectory(const QString& dirPath)
{
    imageDirectoryPath = dirPath;
    saveSettings();
    QModelIndex idx = dirmodel->setRootPath(imageDirectoryPath);
    myTreeView->setRootIndex(idx);
    myTreeView->setCurrentIndex(idx);
 
    QModelIndex first = myTreeView->currentIndex();
 
    qDebug() << "idx" << "row" << idx.row() << idx.column();
    qDebug() << "first" << "row" << first.row() << first.column();
 
    myTreeView->selectionModel()->select(first, 
              QItemSelectionModel::ClearAndSelect | QItemSelectionModel::Rows);
 
}

void DirBrowser::loadDirectory(const QString& dirPath)
{
    imageDirectoryPath = dirPath;
    saveSettings();
    QModelIndex idx = dirmodel->setRootPath(imageDirectoryPath);
    myTreeView->setRootIndex(idx);
    myTreeView->setCurrentIndex(idx);
 
    QModelIndex first = myTreeView->currentIndex();
    
    qDebug() << "idx" << "row" << idx.row() << idx.column();
    qDebug() << "first" << "row" << first.row() << first.column();

    myTreeView->selectionModel()->select(first, 
              QItemSelectionModel::ClearAndSelect | QItemSelectionModel::Rows);

}
