Hi,I'm currently working on a save dialog for my application (currently testing in Ubuntu). The dialog is in accept mode QFileDialog::AcceptSave and a default suffix of "txt" is set. I've noticed something that appears to be strange when the file provided exists as follows (assuming a file "text.txt" exists for the following): 1. If I select the existing file "text.txt" and click save, I am presented with the overwrite question dialog. 2. If I type "text.txt" as the file name and click save, I am presented with the overwrite question dialog. 3. If I type "text" as the file name (without the suffix), I am not presented with the overwrite question dialog and the dialog returns the filename "text.txt" where the default suffix has been added. Number (3) above is concerning. If the dialog returns a filename, I would assume the user has accepted overwriting it, but this doesn't appear to be the case. I assume this isn't intentional and is probably a bug?
Likely, but it requires some investigation on where the bug actually lies.First and foremost, are you using the native (GTK?) file dialog or the Qt one? You can try setting QFileDialog::DontUseNativeDialog and see if it makes a difference.
There are pretty much these cases:A) Native, returning "text.txt" to Qt without showing the overwrite confirmation dialog. A minimal check is in order within Qt to verify that it's opening the native file dialog correctly (with/without any option that would cause such behaviour). This should result in either a bug report against Qt, or a bug report against GTK.
B) Native, returning "text" to Qt which then appends the file extension. Qt bug.
C) Non-native. Qt bug.So, if it is a Qt bug, please report it on the bugtracker. This is obviously a P0, silent data loss.
