Qt - Selecting multiple folders/directories using a dialog

I want to achieve something like the following:

Where I can select multiple folders across multiple drives and retrieve the folder paths of those selected. Qt only has a crude multi-folder selection feature, but it does not support selected folders from other drives etc.

Can anyone guide me on how to create such a dialog? Better yet, does any one have any sample code I could use 开发者_运维知识库(this is an extension to an old project, and I'd much rather save my time and not re-invent the wheel!)

Thanks

You can use QFileSystemModel for represent filesystem on QTreeView. This example explains how to do that.

For checkbox issue, according to this list archives:

The simplest way to do this (I can think of, at least) is to subclass QDirModel and override flags, data and setData:

flags should add Qt::ItemIsUserCheckable to the returned flags data should return the Qt::CheckState of the queried index if the role parameter is Qt::CheckStateRole setData should store the check state of the index

Or, even better, this should work with a QProxyModel pretty much the same way (after all, "favor object composition over class inheritance").

Note that QDirModel class is obsolete. You may not use that on newer Qt versions. I recommend to use QFileSystemModel.
