@VRonin yes - it's a list of QObject*
each entry describes a File:

Folder, File Type (Image, Video, PDF, ...) Path Name (obsolet for iOS Photos) entries (if Folder) ...
and I'm constructing the collection per ex. from PHFetchResult *smartAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeAlbumRegular options:nil];

@ekkescorner @jpnurmi reminds me that there's a problem if you're using multi-line Text inside Flickable.
just tested.
He's right: as long as the TextArea has focus if you try to scroll the selection will be changed instead of scrolling the page.
If you're outside the field scrolling works well

I'll create a bugreport on this soon.
my workaround: I'm placing a small button (w icon) besides the field to toggle word-selection-mode. just tested. this works.

In most cases my TextFields are single line text where selection works well so I can live with this.
