[Interest] Qt 5 and filesystem

[Jason H]

If the OS supports a standard dialog, then QML should provide access to it. It's just that simple.
Who is to say that iOS and other mobile OSs won't provide a standard interface? It is a travesty that they don't. They've been able to avoid it because the disparity between mobile and desktop has been very tangible. But we are in a post-PC world. We are converging iOS with OSX, Windows with Metro, Android with the Atrix lapdock, Ubuntu on Phone is one use case that is likely to be the future. For these convergences, it will be nescessary for the platform to provide a consistent interface that is or replicated the standard dialogs of the PC era. As mobile becomes more of a content creator, we'll need to move data between apps, and the filesystem or file-system derived service is likely to be that mechanism. Similar for apps that want to print. 

Currently, I too want to make a QML application that I can ask the user for a local file. Functionally, I don't care what it looks like. I just want a filename to operate on. Treeview, cloud view, I don't care. But I need that component. On Desktop it'll be a common dialog. Remember back in the day when people didn't use common dialogs and everyone made their own? Then MS improved them and then your application looked dated and limited in function? Common dialog support prevents that from happening. 

At some level, I don't care if it uses ItemViews, especially when no common dialog yet exists. But if the platform has one, then I very much want to use it. That alone is reason to keep the Proxy stuff in Qt5.

It seems they'll be here for a long time, however this discussion looks very similar to ideas of an itemviews-ng project (https://blog.qt.digia.com/blog/2008/10/24/itemviews-the-next-generation/). I didn't look quite close at this project and i wonder - is it used in qt5 somehow in QML world, or does QML still uses QAbstractItemModel and friends?

(Not to mention that the Finder *still* lacks a "File Cut" (CMD + X) operation, even though the menu entry is there (greyed out), probably since OS X 10.0)

My bet is that it uses QAbstractItemModel and friends. iirc the
itemviews-ng project was "alive" before there was any QML idea and was
based on QWidgets, still.
But we're drifting quite a bit here. The question was for filesystem
stuff in Qt.
