NAME
SDL_HINT_FILE_DIALOG_DRIVER - A variable that specifies a dialog backend to use.
SYNOPSIS
#include <SDL3/SDL_hints.h>
#define SDL_HINT_FILE_DIALOG_DRIVER "SDL_FILE_DIALOG_DRIVER"
DESCRIPTION
By default, SDL will try all available dialog backends in a reasonable order until it finds one that can
work, but this hint allows the app or user to force a specific target.
If the specified target does not exist or is not available, the dialog-related function calls will fail.
This hint currently only applies to platforms using the generic "Unix" dialog implementation, but may be
extended to more platforms in the future. Note that some Unix and Unix-like platforms have their own
implementation, such as macOS and Haiku.
The variable can be set to the following values:
• NULL: Select automatically (default, all platforms)
• "portal": Use XDG Portals through DBus (Unix only)
• "zenity": Use the Zenity program (Unix only)
More options may be added in the future.
This hint can be set anytime.
AVAILABILITY
This hint is available since SDL 3.2.0.
