Save file dialog: Cannot set default file name

[GameParrot]

Currently, there is not a way to set the default file name of a save file dialog. Would it be possible to add a property for the default file name?

Which platform have you tested on? Normally, SDL_PROP_FILE_DIALOG_LOCATION_STRING or the location argument should allow providing a default file name, like /path/to/folder/file.ext should open the dialog at /path/to/folder/ and prefill file.ext. #13007 found that the XDG Portal implementation didn't do that already and provided an implementation; if another platform misses that, it should be fixed.

If SDL_PROP_FILE_DIALOG_LOCATION_STRING is set to just file.ext should it just set the name and keep the default location

Which platform have you tested on? This is the expected behavior on all platforms. I just double-checked with Windows and it's the observed behavior; only the Linux implementation (XDG Portals) have a known bug that will be fixed with #13007. If there's another platform that doesn't work as you wrote, please send the details so I can work on a fix.

I think it might not be implemented properly on macOS
Can confirm it is broken on linux
