Sort System Drives via QSortFilterProxyModel

[owais_blore]

I just want to know which function of QSortFilterProxyModel class is used to sort the local and removable drives in system. Basically I am working on a app where I am using treeview and I need to sort them in a order.

Here is the code:

pSystemPrimaryModel = new QFileSystemModel(this);    
pSystemPrimaryModel->setRootPath(QDir::currentPath());
 
QSortFilterProxyModel *proxyModel = new QSortFilterProxyModel(this);
proxyModel->setSourceModel(pSystemPrimaryModel);
proxyModel->setDynamicSortFilter(false);
 
// Set the QFileSystemModel model of QTreeView to display drives
ui->PrimTreeView->setModel(proxyModel);

pSystemPrimaryModel = new QFileSystemModel(this);    
pSystemPrimaryModel->setRootPath(QDir::currentPath());

QSortFilterProxyModel *proxyModel = new QSortFilterProxyModel(this);
proxyModel->setSourceModel(pSystemPrimaryModel);
proxyModel->setDynamicSortFilter(false);

// Set the QFileSystemModel model of QTreeView to display drives
ui->PrimTreeView->setModel(proxyModel);

This displays drives in a regular manner as follows:

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

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