Yes, correct, that is my assumption so far ;) Backed up by the statement "Yes, if you look at the Qt source code it is evident that only the static functions uses native file dialogs. It is not possible to get native dialogs any other way, unfortunately..." (http://stackoverflow.com/questions/2609119/qt-qfiledialog-native-dialogs-only-with-static-functions)

Off course I must admit that a) I did not look at the Qt sources myself and b) whether that also applies to the Mac Qt sources...

I will have this evening ;) And off course I'll let the list know of my findings.

...with the emphasis on *native* file dialogs yes.
 
But off course I agree with you, I would also be very surprised to see on Qt/Mac that native sheet-style file dialogs are not possible! So my hope is also that at least on Mac I get the native dialog with

  QFileDialog *fd = new QFileDialog(...);
  fd->open(...);

Well, let's say "native dialog" instead of "native looking", to make sure we are referring to the same thing ;)

Anyway, that's what I am going to find out tonight.


But at least on Windows you would agree so far that it is not possible to create "Window modal" *native* dialogs ("Window modal": only the parent widget is blocked, not the entire application), right? Unless I am overseeing the obvious here...

Thanks,
