SDL_ShowOpenFolderDialog - Man Page

Defined in SDL3/SDL_dialog.h

#include "SDL3/SDL.h"

void SDL_ShowOpenFolderDialog(SDL_DialogFileCallback callback, void *userdata, SDL_Window *window, const char *default_location, bool allow_many);

This is an asynchronous function; it will return immediately, and the result will be passed to the callback.

The callback will be invoked with a null-terminated list of files the user chose. The list will be empty if the user canceled the dialog, and it will be NULL if an error occurred.

Note that the callback may be called from a different thread than the one the function was invoked on.

Depending on the platform, the user may be allowed to input paths that don't yet exist.

On Linux, dialogs may require XDG Portals, which requires DBus, which requires an event-handling loop. Apps that do not use SDL to handle events should add a call to SDL_PumpEvents
in their main loop.

callback

a function pointer to be invoked when the user selects a file and accepts, or cancels the dialog, or an error occurs.

userdata

an optional pointer to pass extra data to the callback when it will be invoked.

window

the window that the dialog should be modal for, may be NULL. Not all platforms support this option.

default_location

the default folder or file to start the dialog at, may be NULL. Not all platforms support this option.

allow_many

if non-zero, the user will be allowed to select multiple entries. Not all platforms support this option.

This function should be called only from the main thread. The callback may be invoked from the same thread or from a different one, depending on the OS's constraints.

This function is available since SDL 3.2.0.
