#include <allegro5/allegro_native_dialog.h> ALLEGRO_FILECHOOSER *al_create_native_file_dialog( char const *initial_path, char const *title, char const *patterns, int mode)
Creates a new native file dialog. You should only have one such dialog opened at a time. Parameters: · initial_path: The initial search path and filename. Can be NULL. To start with a blank file name the string should end with a directory separator (this should be the common case). · title: Title of the dialog. · patterns: A list of semi-colon separated patterns to match. This should not contain any whitespace characters. If a pattern contains the '/' character, then it is treated as a MIME type (e.g. 'image/png'). Not all platforms support file patterns. If the native dialog does not provide support, this parameter is ignored. · mode: 0, or a combination of the following flags: ALLEGRO_FILECHOOSER_FILE_MUST_EXIST If supported by the native dialog, it will not allow entering new names, but just allow existing files to be selected. Else it is ignored. ALLEGRO_FILECHOOSER_SAVE If the native dialog system has a different dialog for saving (for example one which allows creating new directories), it is used. Else it is ignored. ALLEGRO_FILECHOOSER_FOLDER If there is support for a separate dialog to select a folder instead of a file, it will be used. ALLEGRO_FILECHOOSER_PICTURES If a different dialog is available for selecting pictures, it is used. Else it is ignored. ALLEGRO_FILECHOOSER_SHOW_HIDDEN If the platform supports it, also hidden files will be shown. ALLEGRO_FILECHOOSER_MULTIPLE If supported, allow selecting multiple files. Returns: A handle to the dialog which you can pass to al_show_native_file_dialog(3alleg5) to display it, and from which you then can query the results using al_get_native_file_dialog_count(3alleg5) and al_get_native_file_dialog_path(3alleg5). When you are done, call al_destroy_native_file_dialog(3alleg5) on it. If a dialog window could not be created then this function returns NULL.
