Display System Drives in Specific Order in QTreeView

[owais_blore]

I have a treeview where I am displaying all system drives using QFileSystemModel. I am looking for much better approach where a tree view can display Local Drives in one section, Removable Drive in another and so on.

Here is the code:

pSystemPrimaryModel = new QFileSystemModel(this); 
    /* Sets the directory that is being watched by the model to currentPath by installing
       a file system watcher on it. */
    pSystemPrimaryModel->setRootPath(QDir::currentPath());
    pSystemPrimaryModel->setFilter( QDir::AllDirs | QDir::NoDotAndDotDot );   
    // Sets the model for the view to present.
    ui->PrimTreeView->setModel(pSystemPrimaryModel);    
    // Regard less how many columns you can do this using for:
    for(int nCount = nColCount; nCount < pSystemPrimaryModel->columnCount(); nCount++)
       ui->PrimTreeView->hideColumn(nCount);

pSystemPrimaryModel = new QFileSystemModel(this); 
    /* Sets the directory that is being watched by the model to currentPath by installing
       a file system watcher on it. */
    pSystemPrimaryModel->setRootPath(QDir::currentPath());
    pSystemPrimaryModel->setFilter( QDir::AllDirs | QDir::NoDotAndDotDot );   
    // Sets the model for the view to present.
    ui->PrimTreeView->setModel(pSystemPrimaryModel);    
    // Regard less how many columns you can do this using for:
    for(int nCount = nColCount; nCount < pSystemPrimaryModel->columnCount(); nCount++)
       ui->PrimTreeView->hideColumn(nCount);

To copy to clipboard, switch view to plain text mode 

It gives me the following:

I want to display it like the second picture shown above. How can that be achieved?
