al_create_...ile_dialog(3) Library Functions Manual al_create_...ile_dialog(3) NAME al_create_native_file_dialog - Allegro 5 API SYNOPSIS #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) DESCRIPTION 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 sepa- rator (this should be the common case). * title: Title of the dialog. * patterns: A string containing newline separated sets of patterns to match. A pattern is either a shell-style glob pattern (e.g. "*.txt") or a MIME type (e.g. "image/png"). Not all platforms support both (and some don't even support globs), so a portable solution is to specify a MIME type and simple style globs which Allegro will pick from to match what the platform supports (e.g. do "image/png;*.png"). Multiple patterns are separated using a semicolon. If the platform does not provide support for patterns, this parameter is ignored. Here are some example patterns: * "*.txt" - defines a single filter, matching *.txt files. * "*.txt;*.md" - like above, but matching two types of files. * "Text files (*.txt, *.md) *.txt;*.md" - like above, but with a custom description (separated from the patterns using a space). * "Text files *.txt\nPNG images image/png;*.png" - defines two filters, with the second filter using a MIME type and extension at the same time. Note: Windows does not support MIME types. Android supports only MIME types. Instead of file patterns, MacOS supports extensions, so match- ing based on filename beyond file type does not work. Allegro will parse your file pattern to try to extract the file extension. MacOS also supports MIME types, which behave more predictably. MacOS does not support detailed descriptions or multiple pattern sets, Allegro will strip the detailed descriptions and concatenate all patterns into one list. * 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 exam- ple 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(3) to display it, and from which you then can query the results using al_get_native_file_dialog_count(3) and al_get_native_file_dialog_path(3). When you are done, call al_destroy_native_file_dialog(3) on it. If a dialog window could not be created then this function returns NULL. Allegro reference manual al_create_...ile_dialog(3)
