qt - QML FileDialog nameFilters case sensitive on Linux? -

-

the following code correctly display *.ext , *.ext files on windows , mac. it not display *.ext (and of course *.ext, *.ext, *.ext...) files on linux. what's mistake? 

import qtquick 2.3 import qtquick.dialogs 1.1  filedialog {   title: "please choose file"   namefilters: [ "scene files (*.ext)" ]   selectmultiple: true }

the linux file system case sensitive, , why won't return *.ext files.

the following should work:

namefilters: [ "scene files (*.ext *.ext)" ]
