[Qt-interest] FileFilter

[Predrag Manojlovic]

Hi,

Yes i tried that but that is bad approach. Here is explanation:

If user type name without extension, dialog won't warn for overwrite if
file with extension exists. He will check if file without extension
exists. So, if i modify file name after dialog returns by adding
extension I must check again if file with new name exists and redisplay
Save dialog again or something.

That looks bad in application and makes people confused. In almost all
windows systems (Win, X11, osx) is possible to force extension natively
so i guess such flag is missing here.

Main problem is checking for overwrite.

Any solution for this?

Regards
Predrag
