Wireshark · Wireshark-dev: [Wireshark-dev] File extension is missing on Linux when WiresharkFileDialog::getSaveFileName/QFileDi

[Jirka Novak <j.novak@xxxxxxxxxxxx>]

Hi,

  I noticed that when I would like to save e.g. diagram exports with
Wireshark (not main dialog Save/Save As), it offers me e.g. .pdf, .ps
and other extensions in save dialog. When I write just name of file and
commit the dialog, created file has correct content (PDF, PS, ...), but
filename is missing extension.
  I tested it and it happens just on Linux, but on every Linux I tested
- multiple distributions from past years. On MAC or Windows it works fine.

  I checked the code and it looks that
WiresharkFileDialog::getSaveFileName calls QFileDialog::getSaveFileName
and it returns just name without extension. I tested it with
QFileDialog::DontUseNativeDialog flag too, but same results.
  Then I compared it with CaptureFileDialog and there is method which
checks whether file extension is there and then adds it if it is missing.
  Therefore it looks like Qt feature and some parts of Wireshark code
are aware of it and fix it and some do not.

  Should I try to modify WiresharkFileDialog to handle it for all cases?
