Method selectAll() from QListView does not work properly

[Lykurg]

Use QAbstractItemModel::removeColumn() to remove non needed columns. It will save memory and provides better performance.

I dont know how to use it; especially what to give as a second argument, QModelIndex. I'm pretty sure it cant be be a single item from the model, but dont have any ideas. Can you explain me it a bit more accurately or simply write a small piece of code which will remove single column?

thanks in advance

I see right know that QFileSystemModel does not reimp removecolumns, so you can't use it. Then you have to use the selection options.

Thanks, used selectedRows() and it's working fine
