[Qt-interest] Selecting multiple files on different locations using QFileDialog

[hi]

Hi Andre,

I think you might be displaying tree view where 'List view' or 'Detail
view' show the content, right? But in this case it would be displaying
only currently dir's tree view and when you switch over to other dir
it would have flushed the previous selection.

Thank you.
