Sort the System Drives in QTreeView using QSortFilterProxyModel

[Stoned Jesus]

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

Here is the code:
@pSystemPrimaryModel = new QFileSystemModel(this);
pSystemPrimaryModel->setRootPath(QDir::currentPath());
pSystemPrimaryModel->setFilter( QDir::AllDirs | QDir::NoDotAndDotDot );

// Sets the model for the view to present.
ui->PrimTreeView->setModel(pSystemPrimaryModel);

// Just Display NAME and hide other Columns
for(int nCount = 1; nCount < pSystemPrimaryModel->columnCount(); nCount++)
ui->PrimTreeView->hideColumn(nCount);@

This basically gives me all the drives as follows:
@Name:

• C:
• New Volume(D:)
• New Volume(E:)
• SD_Card(F:)
• Transcend Drive(G:) @

Using hideColumn() I have hidden all the header(Except Name) which gets displayed when QTreeView is used i.e. Name, Type, Size etc.

My Requirement:

1. What I basically want to achieve is this:
   @+ Local Folder
   +C:
   +New Volume(D:)
   +New Volume(E:)

• Removable Drives
  +SD_Card(F:)
  +Transcend Drive(G:)@

Basically separate the local drives and external ones. I have come across QSortFilterProxyModel which looks like it sorts the drive order. But I have no clue how to use that.

2. I want to remove the header in QTreeView. Since Name is visible in my output, I want to hide it. It would be helpful if you could guide me :)
