25 | * File dialog support. | ||
26 | * | ||
27 | * SDL offers file dialogs, to let users select files with native GUI | ||
28 | * interfaces. There are "open" dialogs, "save" dialogs, and folder selection | ||
29 | * dialogs. The app can control some details, such as filtering to specific | ||
30 | * files, or whether multiple files can be selected by the user. | ||
31 | * | ||
32 | * Note that launching a file dialog is a non-blocking operation; control | ||
33 | * returns to the app immediately, and a callback is called later (possibly in | ||
34 | * another thread) when the user makes a choice. | ||
