QDirModel's index overloaded function

[psih128]

Hi

There is an issue with QDirModel that has been puzzling me for quite some time. There is a public function in this class with the following signature:

QModelIndex index(const QString &path, int column = 0) const;

QModelIndex index(const QString &path, int column = 0) const;

To copy to clipboard, switch view to plain text mode 

I have another class that inherits QDirModel:

class MyDirModel : public QDirModel {
}

class MyDirModel : public QDirModel {
}

To copy to clipboard, switch view to plain text mode 

now when I do something like in this:

MyDirModel model;
QModelIndex index = model.index(QString("/Users/anton"), 0);

MyDirModel model;
QModelIndex index = model.index(QString("/Users/anton"), 0);

To copy to clipboard, switch view to plain text mode 

it would give compilation error:

no matching function for call to 'MyDirModel::index(QString, int)'

no matching function for call to 'MyDirModel::index(QString, int)'

To copy to clipboard, switch view to plain text mode 

To workaround this I usually do something like this:

MyDirModel *model;
qobject_cast<QDirModel *>(model)->index(QString('..."), 0);

MyDirModel *model;
qobject_cast<QDirModel *>(model)->index(QString('..."), 0);

To copy to clipboard, switch view to plain text mode 

What's the trick here?

I'm on Qt 4.6 under Mac. Not sure if it's reproducible on Windows

Thanks
Anton

Does your sub-class re-implement the other QDirModel::index (the one that takes int row, int column, const QModelIndex& parent), or declare some other member function named “index”?

If so, that declaration hides all inherited functions by the same name. In that case, you could add:

using QDirModel::index;

using QDirModel::index;

To copy to clipboard, switch view to plain text mode 

to the definition of your derived class to allow overload resolution of the name “index” to include member functions from QDirModel.
