Add new row in QTreeView (Using QFileSystemModel to populate TreeView and QSortFilterProxy model to filter folder)

Hello,

I am using a QFileSystemModel to populate QTreeView and QSortFilterProxyModel to filter folder so that QTreeView show only specific directory. Now I want to add a new row pointing another folder in my QTreeView.
CODE:

"MyProxy.h"

class MyProxy : public QSortFilterProxyModel
{
    Q_OBJECT
-------------------
};

"MyProxy.cpp"

#include "myproxy.h"

MyProxy::MyProxy()
{

}

bool MyProxy::filterAcceptsRow(int source_row, const QModelIndex &source_parent) const
{
    //filter folders
}

"mainwindow.cpp"

#include "myproxy.h"
................
  button=new QPushButton;
   button->setText("Click");


    connect(button,SIGNAL(clicked(bool)),this,SLOT(work()));

    dir=new QFileSystemModel;
    messagesTableWidget=new QTreeView;
    model=new MyProxy;    

void MainWindow::work()
{
    QString folderpath = QFileDialog::getExistingDirectory(this, tr("Open Directory"),
                                                  "/home",
                                                  QFileDialog::ShowDirsOnly
                                                  | QFileDialog::DontResolveSymlinks);

QDir* direct = new QDir(folderpath);
direct->setPath(folderpath);
direct->cdUp();

dir->setRootPath(direc->path());
dir->setFilter(QDir::NoDotAndDotDot |QDir::AllDirs);

model->setSourceModel(dir);
messagesTableWidget->setModel(model);

     messagesTableWidget->setRootIndex(model->mapFromSource(dir->index(direc->path())));
}

So I am using a QFileDialog to select a folder and QDir::cdUp() for parent folder. Now I am using proxy model to filter my folder.

Finally my treeview shows root folder. Now I want to add a row showing another folder in my Qtreeview.

Any Suggestions?
Thanks

Hi,

Apply the same filter you are using for your single folder version except that this time rather than using a QString you should keep a QStringList of the folders you want to show and use that.
