Qt - QFileSystemModel doesn't support the network paths and external drives?
In Qt, the QFileSystemModel
class is primarily designed to work with local file systems. It may not directly support network paths or external drives out of the box.
However, you can implement support for network paths and external drives by subclassing QFileSystemModel
and overriding certain functions. Here's an example of how you can extend QFileSystemModel
to support network paths:
cpp#include <QFileSystemModel>
class NetworkFileSystemModel : public QFileSystemModel
{
public:
explicit NetworkFileSystemModel(QObject *parent = nullptr)
: QFileSystemModel(parent)
{
}
QVariant data(const QModelIndex &index, int role) const override
{
if (role == Qt::DisplayRole && index.isValid()) {
QString path = filePath(index);
if (path.startsWith("//")) {
// Network path, remove the leading slashes
return QVariant(path.mid(2));
}
}
return QFileSystemModel::data(index, role);
}
};
In the example above, the data()
function is overridden to modify the displayed name of network paths by removing the leading slashes. You can then use the NetworkFileSystemModel
class instead of QFileSystemModel
to display network paths correctly.
For handling external drives, you can also extend QFileSystemModel
and override the appropriate functions to detect and handle external drive paths differently.
Keep in mind that this is just a basic example, and you may need to customize it further based on your specific requirements and the behavior you want to achieve.
Remember to include the appropriate header files and adjust the implementation according to your project's needs.
