hi the following will work

QFileSystemModel::setRootPath( "c:\\" )

QFileSystemModel::setRootPath( "c:\\" )

To copy to clipboard, switch view to plain text mode 

hope it helps

Set the path to whatever QDesktopServices::storageLocation() returns for QDesktopServices::DesktopLocation.

I did just as you said but still the application starts from the drivers path (on windows) not the desktop path


I used the following code

m_pFileSystemModel = new QFileSystemModel;
QString dir = QDesktopServices::storageLocation(QDesktopServices::DesktopLocation);
m_pFileSystemModel->setRootPath(dir);
ui->treeView->setModel(m_pFileSystemModel);

m_pFileSystemModel = new QFileSystemModel;
QString dir = QDesktopServices::storageLocation(QDesktopServices::DesktopLocation);
m_pFileSystemModel->setRootPath(dir);
ui->treeView->setModel(m_pFileSystemModel);

To copy to clipboard, switch view to plain text mode 

but i want it to be like this photo

The problem is the second picture does not show the true model of the filesystem.

What does line #2 of your snippet return?

[mismael85]

the second picture is not Qt application it is a visual basic application and i want to make one like it with Qt.
Line #2 returns "C:\Users\mismael\Desktop"

I know. What I say is that it is not a model of your file system.

Line #2 returns "C:\Users\mismael\Desktop"

And when you set it as the root path of your model it still shows some other directory? Make sure you didn't make any mistakes (e.g. read the root path of the model back to see if it is set to the right location). Note - it will not make the dialog show things such as "libraries", "control panel" and stuff as they are artificial entities that are not part of the file system. If you want the exact same output, use native means to get it.

have you done with this?
recently i need my tree to run like the native CMFCShellTreeCtrl either.
if you can mail any tips to my email: seak04#gmail.com will be graceful.
